Exception in thread "main" Could not find the main class: com.sun.tools.javac.Main. Prog



Cause of the error :

Could not create the Java virtual machine.

Error occurred during initialization of VM

Could not reserve enough space for object heap

Resolution:
Change the parameter heap value in the server.xml file to 1024m to 256m.

please execute the following steps:

1. In server.xml (from ORACLE_HOME\j2ee\home\config\) find the following setting:

2. Change it to a lower value (ex. 256M):

3. Restart oc4j

It works now.

If you see issues again with the same jdk1.6 file then try coping the jdk1.5 file and then restart the services.

Thanks,
