Jboss 4.2.1 GA java.lang.OutOfMemoryError: PermGen space

I am using Jboss 4.2.1 GA in my windows7 system. When I run my application I am getting the following error.

2015-03-10 10:33:22,413 ERROR [STDERR] Exception in thread "Thread-30"

when I search it in google, I found the following changes in run.conf file.

  ## -*- shell-script -*- ######################################################

Still I am getting the same error. I don't know what is the issue. Help me. Thanks..

Various IDEs with specify JAVA_OPTS, especially when in debug mode, so a more robust development solution is to add MaxPermSize to all startup configurations.

if [ "x$JAVA_OPTS" = "x" ]; then
   JAVA_OPTS="-Xms256m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -XX:PermSize=128m -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled "
fi

# Sample JPDA settings for remote socket debuging
#JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"

# Sample JPDA settings for shared memory debugging 
#JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_shmem,server=y,suspend=n,address=jboss"

# Enforce larger MaxPermSize
JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=1024m"
