You can add this to the JAVA_OPTS line in either run.bat (Windows) or run.conf (Unix/Linux) in the bin directory. For example (the following change in run.conf should be all on one line): JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000" -Djavax.xml.transform.TransformerFactory=org.apache.xalan.xsltc.trax.SmartTransformerFactoryImpl View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044469#...
