Hi, I downloaded the source-zip-package from jboss.org. to be sure, that the source is compiled an run by jdk1.5 i added the following lines to the build.bat and run.bat to assure that it is compiled and run by my jdk 1.5 | set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_15 | set PATH=%JAVA_HOME%\bin;%PATH% | when i start jboss i get the following log output | =============================================================================== | | JBoss Bootstrap Environment | | JBOSS_HOME: D:\ProgramFiles\jboss-4.2.3.GA-src\build\output\jboss-4.2.3.GA | | JAVA: C:\Program Files\Java\jdk1.5.0_15\bin\java | | JAVA_OPTS: -Dprogram.name=run.bat -server -Xms128m -Xmx512m -Dsun.rmi.dgc.cl | ent.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 | | CLASSPATH: C:\Program Files\Java\jdk1.5.0_15\lib\tools.jar;D:\ProgramFiles\jb | ss-4.2.3.GA-src\build\output\jboss-4.2.3.GA\bin\run.jar | | =============================================================================== for my understanding it is started by a jdk 1.5. i also tried to compile the source with a java 1.6 jdk. doing this i get warning messages in the build log althoug the build seem to work (last log message: success). but i also get the same error when i start the jdk 1.6 compiled jboss. so at the moment i am pretty helpless...
