Hi Abhishek,

We got the similar problem while the installation of the wM 6.0. This can be resolved by adding the following,

export JAVA_COMPILER=none

in the .profile file of the wM user that runs the installer, so that its abailable whenever the webM user runs the installer.

This problem occurs due to the Installer requirement of compiler being turned off.

I hope this should resolve your problem.

Thanks,
Navin
