javac error when running a Play app deployed with Jenkins

[Pramod]

Hi,
I am using Play 1.2.3 with the play-scala module. I am deploying to a
remote machine using Jenkins and SSH. The application starts but I get
this error when trying to load a page. It works fine if I login to the
remote machine manually, cd to the application directory, and run
"play start" on the command line! I have tried exporting JAVA_HOME and
setting $PATH correctly. That didn't help.

Internal Server Error (500) for request GET /

Hi,

You need to install a JDK
