Forgot to give my environment: =============================================================================== JBoss Bootstrap Environment JBOSS_HOME: C:\jboss-4.0.5.GA\bin\\.. JAVA: c:\java\j2sdk1.4.2_11\\bin\java JAVA_OPTS: -Dprogram.name=run.bat -server -Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 CLASSPATH: c:\java\j2sdk1.4.2_11\\lib\tools.jar;C:\jboss-4.0.5.GA\bin\\run.jar =============================================================================== Testing on OS X with Java 1.5 was ok...at least I saw only LDAP errors, because I didn't change the conf-file yet. Is Java 1.5 a prerequisite!? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990000#...
