[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - PermGen error

[oneworld95]

We're getting this error when we redeploy a Seam application: 

2009-07-02 10:11:30,745 WARN  [org.jboss.system.ServiceController] Problem starting service jboss.web.deployment:war=forms_new_employee.war,id=-1855897005
  | java.lang.OutOfMemoryError: PermGen space
  | ....
  | 2009-07-02 10:11:59,745 ERROR [STDERR] java.lang.OutOfMemoryError: PermGen space
