java.lang.OutOfMemoryError: Java heap space on Tomcat 6
I have generated a project using QWicket. I ran the build on Tomcat 6 and the
initial user registration and user authentication worked fine. I added a
simple form and insert those values into the database using Spring +
Hibernate. While submitting the form, the values are getting inserted into
the database. But during the navigation part, the application times out with
the following error
I modified the QWicket generated code to use Wicket 1.3 beta 3 build.
Root cause:
java.lang.OutOfMemoryError: Java heap space
Complete stack:
org.apache.wicket.WicketRuntimeException: Method onFormSubmitted of
interface org.apache.wicket.markup.html.form.IFormSubmitListener targeted at
component [MarkupContainer [Component id = trip, page =
com.tripos.page.NewTripPage, path = 3:trip.NewTripPage$NewTripForm,
isVisible = true, isVersioned = true]] threw an exception

at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:261)
The environment is Tomcat 6 running on OS X Tiger on Mac Mini with 512 MB
ram. I added Java_OPTS to have JAVA_OPTS="-Xms512m -Xmx512m".
Is this problem because of insufficient memory?

If youre only running a simple form, and dont have 1000's of users it
should be fine, something else must be wrong.
Might be your parameters.
A guy on this
thread(http://forum.java.sun.com/thread.jspa?threadID=326216) said:
"Don't set the maximum memory to above 70% of the physical memory of the
box or it will grind to a halt. The JVM needs all of the heap to be in
physical memory all the time."
You can adjust heap by lowering your parameters, try with 128 in both
instead.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
JVM starts with -Xms amount of memory for the heap (storing objects
etc.) and can grow to a maximum of -Xmx amount of memory.

It is probably a good idea to profile your application. With 512 MB
you should typically be able to serve a couple of thousand concurrent
sessions without problems with Wicket 1.3.
