PermGen is a region of memory maintained by the JVM for things like class definitions. The default size is notoriously small for web apps, and you can easily run out, especially if you re-deploy the application multiple times without restarting the app server.
Try re-starting Tomcat rather than just re-deploying the app. If that doesn't work, add the following option to the command line for starting Tomcat: -XX:PermSize=50m This gives you a 50 meg PermGen area. Increase as necessary. jk On Wed, Dec 05, 2007 at 01:15:32PM +0000, James Perry wrote: > Checking my Tomcat's server log (catalina.out), it appears the issue is: > ERROR - [wicketcart] - Servlet.service() for servlet wicketcart > th > rew exception > java.lang.OutOfMemoryError: PermGen space > at sun.misc.Unsafe.defineClass(Native Method) > at sun.reflect.ClassDefiner.defineClass(ClassDefiner.java:45) > at > sun.reflect.MethodAccessorGenerator$1.run(MethodAccessorGenerator.jav > a:381) > at java.security.AccessController.doPrivileged(Native Method) > at > sun.reflect.MethodAccessorGenerator.generate(MethodAccessorGenerator. > java:377) > at > sun.reflect.MethodAccessorGenerator.generateSerializationConstructor( > MethodAccessorGenerator.java:95) > at > sun.reflect.ReflectionFactory.newConstructorForSerialization(Reflecti > onFactory.java:313) > at > java.io.ObjectStreamClass.getSerializableConstructor(ObjectStreamClas > s.java:1327) > at java.io.ObjectStreamClass.access$1500(ObjectStreamClass.java:52) > at java.io.ObjectStreamClass$2.run(ObjectStreamClass.java:437) > > > Any thoughts? > > On Dec 5, 2007 1:00 PM, James Perry <[EMAIL PROTECTED]> wrote: > > Bare with me.
