I'm not a big fan of Eclipse but sometimes I use it to deploy apps on Google app-engine. So today morning I woke and was all set to deploy my new python app on Google's app engine and that's when noticed the below quoted error.

An error has occurred. See the log file
/home/rupali/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1336830746877.log.

I tried running a few commands suggested by forums but they returned with an error.

 sudo update-alternatives --config java

There is only one alternative in link group java:
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java Nothing to configure.

Help me please !
