I have been trying to implement a context listener that will allow me to have different repositories for each web application that is deployed. I was using several examples that I googled and keep getting java Verify errors. When tailoring it down line by line I finally got the following: java.lang.LinkageError: loader constraints violated when linking org/apache/log4j/Level class at org.apache.log4j.spi.WebAppRepositorySelector.init(WebAppRepositorySelector.java:36) at biz.ormia.util.logging.ContextRepositoryListener.contextInitialized(ContextRepositoryListener.java:40 I intend to post more detailed code and such but I was wondering what is the appropriate forum to post this question to for the best response? OS: OSX 10.5 (on intel mac) jboss: 4.2.1 GA & 5.0.1 GA Thanks, steve View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228783#...
