First of all, system is running now :) Thank you! Now i will check out my first portlet and then lets see how we can integrate our old Supervisory Controls & MES application in this mighty JBoss stuff :) MaxPermSize is configured, but in run.conf - and this file is never used in a windows system, so its missing in run.bat. run.bat has to be updated with set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -XX:MaxPermSize=256m and it would be a good configuration hint if you add set JAVA_OPTS=%JAVA_OPTS% -Dhttp.proxyHost={proxy ip} -Dhttp.proxyPort={proxy port} -DproxySet=true View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185614#...
