Cisco Unified JTAPI Installation

This chapter describes how to install and configure the Cisco Unified JavaTelephonyAPI (JTAPI) client software for Cisco Unified Communications Manager.

Overview

The Cisco Java Telephony API (JTAPI) implementation comprises Java classes that reside on all client machines that run JTAPI applications. Installation of the Cisco Unified JTAPI client must take place before these applications can function correctly. Make sure that the Cisco Unified JTAPI classes are installed wherever JTAPI applications run, whether on Cisco Unified Communications Manager Administration, a separate machine, or both.

Supported JVM Versions for Cisco Unified Communications Manager Administration

For a detailed breakdown of supported JVM versions for this release of Cisco Unified Communications Manager, see https://developer.cisco.com/site/jtapi/documents/cisco-unified-jtapi-supported-jvm-versions/.


Note

If you have upgraded from Cisco Unified Communications Manager Administration 4.x to 5.0 or later, you must upgrade the JTAPI client software on any application server or client workstation on which JTAPI applications are installed. If you do not upgrade the JTAPI client, your application fails to initialize.

Upgraded JTAPI client software does not work with previous releases of Cisco Unified Communications Manager.

Required Software

Cisco JTAPI requires the following software:

  • Cisco Unified Communications Manager

  • Supported Operating System Platform

Installing the Cisco Unified JTAPI Software

You can install the Cisco Unified JTAPI software in these modes:

  • Silent Install Invocation

  • Command Line Invocation

  • End User Installation

The installer temporarily installs a Java Runtime Environment (JRE) version and uses it for its operation. The system removes the JRE during the uninstall process.


Note

Distribution of the JRE with the Cisco Unified JTAPI Installer occurs in accordance with an agreement between Oracle/SunMicrosystems, Inc., and Cisco Systems, Inc.

Silent Install Invocation

Applications can bundle the JTAPI Installer along with their installation by using a silent install invocation of the JTAPI Installer.

Applications that run the JTAPI Installer in silent mode can use the following commands:

  • Linux (32-bit) platforms—CiscoJTAPIClient-linux –silent

  • Windows (32-bit) platforms—CiscoJTAPIClient.exe –silent

For Cisco Unified Communications Manager 8.6(1) and later, for 64 bit installer on a 64 bit Operating System (OS), the applications can use the following commands:

  • Windows platforms—CiscoJTAPIx64-Windows.exe -i silent

  • Linux RedHat platforms—CiscoJTAPIx64-Linux.bin -i silent

TFTP settings can be passed during a silent install with the following command (For Windows and Linux):

  • CiscoJTAPIx64-Windows.exe - silent -DKEY_TFTPIP = "IP address"

When you are performing a fresh install or an upgrade/downgrade, the JTAPI Installer automatically detects the destination folders and performs a silent install. The installer places the JTAPI Sample Applications and the JAR Files in the appropriate folders that are specified during installation or in the default folders during a silent install. However, if a previous version is present, the JTAPI Installer does not know the application path, so it creates the default folders, Lib and JTAPITools, and installs the applications in those folders.

For Windows clients, the JTAPI Installer also updates the registry with the new install information. For Linux versions, it creates the file jtapiver.ini in the users home directory.


Note

When using Windows 7 and Windows 2008 Server, you must disable the User Access Control (UAC) service for the silent installation process to succeed.

Command Line Invocation

To run the JTAPI Installer interactively from the command line, enter one of the following commands from the command prompt:

  • Linux (32 bit) platforms—CiscoJTAPIClient-linux.bin –console

  • Windows (32 bit) platforms—CiscoJTAPIClient.exe -console

For Cisco Unified Communications Manager 8.6(1) and later, for 64 bit installer on a 64 bit OS, use the following commands:

Windows (64 bit) platforms—CiscoJTAPIx64-Windows.exe -i console

Linux (64 bit) platforms—CiscoJTAPIx64-Linux.bin -i console

For more information on supported platforms for JTAPI, see Supported Platforms.

The command line mode is helpful for installing JTAPI in systems that do not have GUI support, such as Linux systems. A character-based menu, where the user is asked to provide a series of inputs based on the install time conditions, guides the entire installation procedure. All installation parameters are available during the console mode installation.

You will find that the command line mode is helpful for installing JTAPI in systems that do not have GUI support, such as Linux systems. A character-based menu, where the user is asked to provide a series of inputs based on the install time conditions, guides the entire installation procedure. This mode also provides all the other options that the GUI-based installer provides.


Note

If you perform a reinstall/upgrade/downgrade on Linux in console mode and select the option for ‘Uninstall Current Version’, the client is uninstalled but the screen does not display a progress indicator. Once the uninstall is complete, you are notified through the console panel and the installer exits.

End User Installation

The JTAPI Installer uses a Java Foundation Classes (JFC) swing interface for the end user interface. Theinstall procedure asks the user to provide a series of information and checks.

The installer creates and installs uninstallers on the target system, under the folder "_uninst." You can find this folder under the JTAPI application path, which is normally C:\Program Files\JTAPITools for Windows and $HOME/.jtapi/bin for Linux. You can invoke the uninstaller by using this path.

A log file that is named ismpInstall.txt (orismpUninstall.txt) in the folder from which the installer/uninstaller is executed stores all details about the installation procedure. You can also use this file to check for any errors that may occur because it contains the entire list of traces of the various events that occur during client installation.

For Cisco Unified Communications Manager 8.6(1) and later, JTAPI Client supports installations on 64 bit platforms. The installer created using the InstallAnywhere tool installs JTAPI tools and applications under the default folder C:\Program Files\Cisco\JTAPI64Tools\ for Windows. For Linux, JTAPI tools and applications are installed at $HOME/.jtapi64/. The uninstaller is located in the same directory under the _uninstaller directory. The library files (jtapi.jar, jtracing.jar and updater.jar) are installed in the lib folder under the parent directory.

A log file, InstallLog_stout.txt/ InstallLog_sterr.txt is created under the user home directory, like in Windows C:\Documents and Settings\Administrator. It stores all details about the installation procedure. You can also use this file to check errors because it contains the entire list of traces of the various events that occur during product installation.

OS Platform Check

You cannot install a 64-bit JTAPI client on a 32-bit OS. If you attempt this, the following error screen will pop-up to abort the installation[ windows platform].

Installation will abort on Linux platform as well, with a similar error.

Install operations supported/not supported:

  1. Installation of 32-bit JTAPI client on 64-bit OS is supported. Installation will be successful. Installer will run under WOW64, that is, all files/folders/registry of WOW64 settings will be used.

  2. Installation of 64-bit JTAPI client on 32-bit OS is not supported. Installation will fail with the error message: Windows error 193 occurred while loading JVM.

  3. Installation of 32-bit JTAPI client on 32-bit OS is supported. Installation will proceed successfully( Normal installation)

  4. Installation of 64-bit JTAPI client on 64-bit OS is supported. Installation will proceed successfully( Normal installation)

Installation Procedures

Linux Platforms

Cisco Unified JTAPI supports multiple languages for the installation and JTAPI Preferences user interface.

The Cisco Unified JTAPIInstaller installs the following items on the local disk drive:

  • JTAPI java classes in $HOME/.jtapi/lib

  • JTAPI Preferences in $HOME/.jtapi/bin

  • JTAPI sample applications (makecall, jtrace) in $HOME/.jtapi/bin

  • JTAPI documentation in $HOME/.jtapi/bin/doc

Applicable from 8.6 release:

For 64-bit JTAPI Installer on 64-bit OS:

  • JTAPI java classes in $HOME/.jtapi64/lib

  • JTAPI Preferences in $HOME/.jtapi64/bin

  • JTAPI sample applications (makecall, jtrace) in $HOME/.jtapi64/bin

  • JTAPI documentation in $HOME/.jtapi64/bin/doc

Perform the following steps to install the Cisco Unified JTAPI software on a Linux platform:

  1. Log in to the computer where you want to install the Cisco Unified JTAPI client software.

  2. Locate the appropriate ISMP/IA installer and launch it:

Applicable from 8.6 release::

For 64-bit JTAPI Installer on 64-bit OS,

  • CiscoJTAPIx64-Linux.bin - for Linux OS

  1. Log in to the computer where you want to install the Cisco Unified JTAPI client software.

  2. Locate the appropriate ISMP/IA installer and launch it:

  3. Follow the instructions that the Cisco Unified JTAPI Installer presents.

Verifying Linux Installation

To ensure that the JTAPI installation has been done properly, perform the following steps:

Procedure

Step 1

Check that the .jtapiver.ini file is created in the $HOME directory.

Step 2

Check that the JTAPI Program files and documentation are present under the folder $HOME/.jtapi/bin.

Look for the makecall, jtrace, Locale_files, and doc folders.

Step 3

Check that the JTAPI Library is present under the folder $HOME/.jtapi/lib.

Look for the jtapi.jar, jtracing.jar, and updater.jar files.

Step 4

After ensuring that jtapi.jar is present in the classpath, run the following command from the command line prompt of $HOME/.jtapi/bin ./_jvm/bin/java:

com.cisco.services.jtprefs.jtprefsFrame

The JTAPI Preferences dialog box appears.

Note

 

In the absence of the JTPrefs application, you can generate the jtapi.ini file by entering:

< jview | java > CiscoJtapiVersion -parms

This command generates a jtapi.ini file in the current directory.

For Cisco Unified Communications Manager 8.6(1) and later, for 64 bit installer on a 64 bit OS, the default install directory is $HOME/.jtapi64/.

After installation, CLASSPATH is updated with the location of jtapi.jar. For linux a file .jtapiver.ini is updated with the install location in user home directory. For classpath changes to take effect, you need to log off and login again.

During installation, you can choose a different folder than $HOME to install JTAPI. In this case, the system creates a folder called .jtapi within the specified folder and creates the bin and lib folders within that folder for copying the corresponding files. For example, if you choose the folder name /home/jtapiuser, the folder structure would be

/home/jtapiuser/.jtapi/bin (for 32 bit installers)—Contains the makecall, jtrace, Locale_files, and doc folders.

or

/home/jtapiuser/.jtapi64/bin (for 64 bit installers)

/home/jtapiuser/.jtapi/lib(for 32 bit installers)—Contains the jtapi.jar, jtracing.jar, and updater.jar files

or

/home/jtapiuser/.jtapi64/lib (for 64 bit installers)

In this case, run the command at Step4 from the /home/jtapiuser/.jtapi/bin folder (for 32 bit installer) or /home/jtapiuser/.jtapi64/bin folder (for 64 bit installer).

Windows Platforms

Cisco Unified JTAPI supports multiple languages for the installation and JTAPI Preferences user interface.

Verifying Windows Installation

To verify the JTAPI Windows installation, you can use the makecall application that allows you to place a call via JTAPI. Perform the following steps to use the makecall application.

Procedure

Step 1

From the Windows command line, navigate to the directory where you installed Cisco Unified JTAPI Tools. By default, this directory is C:\ProgramFiles\JTAPITools (for 32 bit installers) and C:\ProgramFiles\JTAPI64Tools (for 64 bit installers).

Step 2

Execute the following command:

java CiscoJtapiVersion

Step 3

Execute the following command:

java makecall <server name> <login> <password> 1000 <phone1> <phone2>

Note

 

The server name variable specifies the hostname or IP address of the Cisco Unified Communications Manager (for example, 192.168.1.100 or Subscriber2).

The phone1 and phone2 variables designate directory numbers of IP phones or virtual phones that the user controls according to the user configuration. Refer to the chapter ‘Directory Number Configuration’ in Cisco Unified Communications Manager Administration Guide for details.

For the login and password variables, use the user ID and password that you configured in the Cisco Unified Communications Manager User Configuration window.

Determining the Current JTAPI Version

To determine the JTAPI version number from the installer, use one of the following commands:

  • CiscoJtapiVersion.exe - silent -W newversion.check = ”1” -goto showversion

  • CiscoJtapiClient-linux.bin -silent -W newversion.check = ”1” -goto showversion

For Cisco Unified Communications Manager 8.6(1) and later, for 64 bit JTAPI Installer on 64 bit OS, use one of the following commands;

  • CiscoJTAPIx64-Windows.exe -i silent -DKEY_VERSION_TEXT = "1"

  • CiscoJTAPIx64-Linux.bin -i silent -DKEY_VERSION_TEXT = "1"

These commands create a file called "jtapiversion.txt" in the folder where you execute the command. This file contains the JTAPI version in the format A.B(C.D)-E.

When a previous JTAPI version is present in the system and an upgrade is made to the current version of JTAPI, the installer invokes the uninstaller of the previous release. If you want to invoke the previous uninstaller in silent mode on a Windows system, use the command 

CiscoJtapiClient.exe -silent -W newversion.silent = ”1”

If it is installed, you can also use the JTAPI Preferences user interface utility tool to verify the installed JTAPI version.

Procedure

Step 1

Choose Start > Programs > CiscoJTAPI > JTAPI. The following menu displays:

Step 2

Select the "ReadMe" file. This file identifies the currently installed version of Cisco Unified JTAPI.

Using Cisco Unified CM JTAPI

The following section describes the program group and program elements created by the installation of Cisco JTAPI.

Security Tab

The following figure illustrates the Security tab of the preferences application.

Figure 5. Security Tab


Administrators need to configure the User Name, Instance ID, Authorization Code, TFTP Server IP-Address, and CAPF Server IP-Address parameters through the JTAPI Preferences application before invoking the JTAPI API or JTAPI Preferences to download/install certificates on the application server.

You can use JTAPI Preferences to configure security profiles for one or more User Name/Instance ID pairs. If an application user has previously configured a security profile for a User Name/Instance ID pair, the security profile automatically populates when the user enters the User Name/Instance ID and clicks any of the other edit boxes.

Apart from the GUI that is provided through JTAPI Preferences, an application can also install a client certificate by calling the interface that is provided at CiscoJtapiProperties. When Interface UpdateCertificate is called, the JTAPI client connects to the TFTP server to download the CTL file and extract certificates to the given certificate path. It then connects to the CAPF server to download the client certificate and installs it into the given certificate path.

The jtapi.ini files store user security records in comma separated value (CSV) format. Semicolons separate individual records. An example of a users security record is as follows:

SecurityProperty = user, 123, 12345, 172.19.242.37, 3804, 172.19.242.37, 69, .\\, true, false;<next record>; …

Administering User Information for JTAPI Applications

The JTAPI application requires that users be given the privilege to control one or more devices. Follow the procedures for adding an application user and assigning devices to an application user in the "Application user setup" chapter of the Cisco Unified Communications Manager Administration Guide before using the JTAPI application. The list of devices that are assigned to the user represents the phones that the user needs to control from the application (for example, make calls and answer calls).

Fields in the jtapi.ini File

Applications that run in non-GUI-based platforms, where the JTAPI Preferences application cannot be invoked, can write their own jtapi.ini file and place it along with jtapi.jar based on the values that are provided here. JTAPI will make use of these values.

Applications should ensure that they provide valid data as described in the following table. Applications are responsible for errors that are caused in JTAPI behavior due to improper jtapi.ini file values.

TracePath

.

NA

NA

This field specifies the path name to which the trace files are written. When the path is not specified, JTAPI makes the application path as the default.

FileNameExtension

log

NA

NA

This field specifies a numerical index that is appended to the file base name to indicate the order in which the files are created. For example, if you enter jtapiTrace in the File Name Base field and log in the File Name Extension field, the trace files would rotate between jtapiTrace01.log, jtapiTrace02.log, and jtapiTrace10.log. If the File Name Base and File Name Extension fields are left blank, Cisco Unified JTAPI picks the trace files names as CiscoJtapi01.log, CiscoJtapi02.log, and so on.

SyslogCollector

FALSE

NA

NA

This field specifies you to direct the traces to a specific path and folder in the system. No fewer than two log files and no more than 99 files can exist. Cisco Unified JTAPI rotates through the log files in numerical order, and returns to the first log file after filling the last. Log files increase in size in 1-megabyte increments.

TraceFileSize

1048576

1048576

NP

This field allows you to specify the maximum size of log files to be written.

UseAlarmService

0

10

NP

This field specifies the time in seconds that JTAPI will wait for a response for the Provider Open Request. The default is 10 seconds.

JtapiPostConditionTimeout

15

10

20

JTAPI has post conditions for events, and if the post condition is not met before a timeout, JTAPI will throw exceptions. Use this field to set the timeout value of such conditions.

ApplicationPriority

2

NA

NA

This field prioritizes multiple provider open requests. Currently, JTAPI only sends a default value.

SecurityTraceEnabled

FALSE

NA

NA

This field enables tracing for security-related messages.

You can enable (or disable) tracing for certificate install operations by selecting this check box and selecting the desired trace level.

AlarmServicePort

1444

NP

NP

This field is used for sending alarms to a different server. Users can select the alarm server host name and port on which the service is running, and JTAPI will send the alarms to the specified server and port.

This field specifies the time, in seconds, that JTAPI will retry opening a connection to the Cisco Unified Communications Manager cluster in case of system failure.

QueueStatsEnabled

FALSE

NA

NA

This field is used by JTAPI to log the max queue depth over the specified number of messages that are queued to JTAPI main event thread. In other words, for every x messages processed, JTAPI logs a DEBUGGING level trace that reports the maximum queue depth over that interval, where x represents the number of messages that are specified in Queue Size Threshold.

FileNameBase

CiscoJtapi

NA

NA

This field specifies a value to create the trace file name.

PeriodicWakeupEnabled

FALSE

NA

NA

This field enables (or disables) a heartbeat in the internal message queue that JTAPI uses. If JTAPI has not received a message in the time that is defined in PeriodicWakeupInterval, it causes the thread to wake up and creates a log event.

JTAPINotificationPort

2789

1

NP

This field specifies the Port through which the JTAPI parameter changes are communicated to JTAPI applications during runtime.

PeriodicWakeupInterval

50

NP

NP

This field allows you to define a time of inactivity in the JTAPI internal message thread. If JTAPI does not received a message during this time, the thread wakes up and logs an event.

QueueSizeThreshold

25

10

NP

This field allows you to specify the number of messages that define the time over which JTAPI will report the maximum queue depth.

UseSystemDotOut

FALSE

NA

NA

This field is used to display traces on the console.

UseSameDirectory

1

NA

NA

This field allows you to specify whether the same folder name must be used for each instance of an application.

When this option is enabled, JTAPI traces the log files to the same directory. In this case, successive instances of a JTAPI application will restart the log files, starting at index 01.

When this option is disabled, each instance of the application, whether successive or simultaneous, will cause the trace files to be placed in a new folder sequential to the last folder that was written. Cisco Unified JTAPI detects the last folder in the trace path and automatically increments the numeric index.
