does jboss treecache need log4j-1.2.9.jar

[sreepraveen_2000]

we are using jboss treecache with hibernate 3.0, my question is does treecache need log4j-1.2.9.jar (is it mandatory). when ever we remove the log4j-1.2.9.jar from classpath it throws java.lang.NoClassDefFoundError exception.

Unless you don't use log4j (e.g. use the JDK logger), this JAR is not mandatory.

Actually, TreeCache extends ServiceMBeanSupport, and that imports log4j's NDC class. So, log4j is required. Removing the the tie to ServiceMBeanSupport is on the JBossCache roadmap; this would remove the log4j dependency. I also think it would be good to abstract away the NDC usage in ServiceMBeanSupport so there is no static link to log4j.

Oh s**t ! Can we create a JIRA issue to remove the dependency on NDC ?

Yes, there should be no explicit log4j dependencies in the core services/apis.
