Hello I have the following setup: Ubuntu Server 8.0.4.1 vmware image with 512MB RAM Sun Java JRE build 1.6.0_07-b06 JBoss 4.2.2.GA Im am running one Grails web application on the server. Whenever I run the report generation functionality of my application I get an out of memory exception (out of perm space :-( ) This application worked when running under Jetty. Is Java 6 recommended for JBoss 4.2.2.GA??? Should I use Java 5 instead? What do you think could be my problem? Thank you View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4220792#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
