JRE version in Cisco IP Communicator

                   JRE is included with the Cisco IP Communicator installation. Is there any reference info with the JRE version that comes with certain versions of IP communicator? And can you explain how it verifies, and/or upgrads the version of JRE that exists on the client PC when IP Communicator installs? We are not sure if it is affecting the latest JRE updates that are pushed to our laptop PCs. Thanks.

JRE version in Cisco IP Communicator

Hi George,

You can check the relase notes of each IPC version to find out the JRE versions.

JRE version in Cisco IP Communicator

Thanks Anand, but I have searched through the release notes and don't see any reference to the JRE version for IPC. Am I missing it smewhere, or is there any other reference? Also, do you know what action the IPC installation takes if it detects that the existing JRE is a previous version, or a newer version compared to the install version? Thanks, George

JRE version in Cisco IP Communicator

Hi George,

Apologies, these release notes were referring to some Security vulnerabilities with some specific JRE versions.

You can check the currently runing JRE version using:

This cannot be verified from UI, but you can verify from command-line (see command and output below).

C:\Program Files\Cisco Systems\Cisco IP Communicator\JRE\bin\java.exe" -version java version "1.4.2_19" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_19-b04) Java HotSpot(TM) Client VM (build 1.4.2_19-b04, mixed mode)

Not sure about the second part of this query, will let others to comment on that.

Thanks,

Re: JRE version in Cisco IP Communicator

The version of Java in CIPC is very old. Is there a way to update the JRE version in use? Jabber continues to not be an option for us as it does not support multi line which is a requirement in our environment.

 

We are forced to continue to use and support CIPC but the JRE is very old. When attempting to update the JRE folder with a new version of java, files are LOCKED in windows.
