[jboss-dev] obtain server connection vs jboss-logging

Hallo, Hope I use the right list. I'm creating a connection to JBoss AS as part of JBASM-3. See below for code and exception. I can workaround it by setting "org.jboss.logging.Logger.pluginClass" to "logging.JDK14LoggerPlugin". But as server manager could be running in any environment I guess blindly setting this system property is not desirable. Any other ways I can fix that? Actually the code works but the exception is visible to the user. Code like: ctx=new InitialContext(properties); MBeanServerConnection connection = (MBeanServerConnection) ctx.lookup("jmx/rmi/RMIAdaptor"); connection.invoke("jboss.system/type/Server", "shutdown",null,null); *outputs* an exception: [server:stop] Shutting down server: profileservice [server:stop] java.lang.NoClassDefFoundError: org/apache/log4j/Priority [server:stop] at java.lang.Class.getDeclaredConstructors0(Native Method) [server:stop] at java.lang.Class.privateGetDeclaredConstructors(Class.java:235 7) [server:stop] at java.lang.Class.getConstructor0(Class.java:2671) [server:stop] at java.lang.Class.newInstance0(Class.java:321) [server:stop] at java.lang.Class.newInstance(Class.java:303) [server:stop] at org.jboss.logging.Logger.getDelegatePlugin(Logger.java:312) [server:stop] at org.jboss.logging.Logger.<init>(Logger.java:78) [server:stop] at org.jboss.logging.Logger.getLogger(Logger.java:291) [server:stop] at org.jnp.interfaces.NamingContext.<clinit>(NamingContext.java: 162) [server:stop] at org.jnp.interfaces.NamingContextFactory.getInitialContext(Nam ingContextFactory.java:55) ... Thanks much, Aleksandar
