Note: Oracle Java 8 does not have a separate permanent generation space any more. The -XX:(Max)PermSize option makes no difference (the JVM will ignore it, so it can still be present). If you see java.lang.OutOfMemoryError: PermGen space errors, you need to increase java.lang.outofmemoryerror permgen space tomcat the permanent generation space available to Eclipse. PermGen is the permanent generation of objects in the VM (Class names, internalized strings, objects that will never get garbage-collected). An easy, if somewhat memory-hungry fix is to enlarge the maximum space for these objects by adding -XX:MaxPermSize=128M as an argument to the JVM when starting Eclipse. The recommended way to do this is via your eclipse.ini file. Alternatively, you can invoke the Eclipse executable with command-line arguments directly, as in eclipse [normal arguments] -vmargs -XX:PermSize=64M -XX:MaxPermSize=128M [more VM args] Note: The arguments after -vmargs are directly passed to the VM. Run java -X for the list of options your VM accepts. Options starting with -X are implementation-specific and may not be applicable to all JVMs (although they do work with the Sun/Oracle JVMs). Eclipse and Sun VMs on Windows Eclipse 3.3 and above supports an argument to the launcher: --launcher.XXMaxPermSize. On Windows, Eclipse ships with the following lines in the eclipse.ini file: --launcher.XXMaxPermSize 256m With the above arguments, if the VM being used is a Sun VM and there is not already a -XX:MaxPermSize= VM argument, then the launch

Tomcat is run in its own JVM instance, so you'll need that separately. Assuming you use WTP to start your Tomcat instance, you need to go to your Server configuration, click "Open launch configuration" and there (on the "Arguments" tab) edit/add the VM arguments to include the desired -XX:MaxPermSize argument. share|improve this answer answered Oct 24 '11 at 15:52 Joachim Sauer 184k35394501 3 adding the argument to the end of the variables, right: -Dcatalina.base="C:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0" -Dcatalina.home="D:\apache-tomcat-7.0.22" -Dwtp.deploy="C:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps" -Djava.endorsed.dirs="D:\apache-tomcat-7.0.22\e
