run another java application

Question

Hello.

I have got a Ubuntu server running JIRA.

Now I want run on the same server another JAVA application, but I would like use the same JAVA installartion that comes with JIRA.

My other application requires set JAVA_HOME.

Does someone knows where is the JIRA JAVA_HOME directory?

Thanks.

Hi Manel,

You need to "export" the variable as export JAVA_HOME=<PATH_TO_JVM>, however I think the best way for you to handle this situation is to have multiple Operating System users, one for each application, and then you can specify the JAVA_HOME variable for each user in their bash profiles so that they run at startup, as described here: http://www.cyberciti.biz/faq/linux-unix-set-java_home-path-variable/

This allows you to make each Operating System user responsible for a different application and will allow you to specify two different JAVA_HOME variables for the two different applications. I think that using the same JVM for both applications is doomed to failure and I believe the most likely reason JIRA isn't starting up is because of this conflict so using two separate users and two separate JVMs is the solution here.

All the best,
John

Thanks for the answers.

I check where is my JAVA_HOME and the other environment paths that the error shows me, I tried to point the variables to the paths that I think that must point, but the application doesn't run.

Look this image:

Does someone knows what could I do? What paths should I change?

thanks again.
