If anybody have solution, pls let me know …Thanks in Adavnce…

It sounds like you’'re using the wrong JDK version to run the application. Is JDK 1.5 installed on your machine and set as the default JVM?

When you launch using the launcher – is there anything in the error logs?



Thanks…I am using JDK version 1.4… This may be the problem…but i havn’'t seen any prerequites in installation guide…

After starting Jive server I am hitting “Launch Admin” Button…

JDK 1.5 is required, as outlined int the installation guide:

In order to install Jive Messenger, you’'ll need a server environment that meets the following requirements:

  • JDK 1.5 or later. You can check your java version by typing “java -version” at the command line. See http://java.sun.com for Java on your platform or download a Jive Messenger installer with bundled JVM for your operating system.

  • A supported database with a robust JDBC 2.0 compliant driver. Supported databases and recommended JDBC drivers are detailed in the database documentation below. Alternatively, you can use the embedded database.
