running grails application in Geronimo

Question

I am running into issues where by my grails web-app is unable to start in geronimo. These are the version I am running with - Grails version 1.3.7 - Geronimo version 2.1.1 whatever I do application fails to start with varied exceptions mostly tied to perm-gen errors

Some of the exceptions I end up getting are

09:43:27,733 ERROR [ReloadAwareAutowireCapableBeanFactory] Destroy method on bean with name 'eventTriggeringInterceptor' threw an exception
java.lang.OutOfMemoryError: PermGen space
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:616)
    at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141)
    at org.apache.geronimo.kernel.classloader.JarFileClassLoader.access$200(JarFileClassLoader.java:52)
    at org.apache.geronimo.kernel.classloader.JarFileClassLoader$6.run(JarFileClassLoader.java:308)

I really need some help here, I am stuck what to do next or how to resolve. I used

set JAVA_OPTS= -Xmx1024m -XX:MaxPermSize=256m in geronimo.bat 

but that didn't help either

Answer 1

changing the options to

set JAVA_OPTS=-verbose:gc -Xmx756m -XX:MaxPermSize=256m

did the trick for me.
