Hi I'm using latest opensaml software and JBOSS 4.0.4GA.

When my war file gets loaded I get the following error:

11:56:39,296 ERROR [[/Security]] StandardWrapper.Throwable
java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z
 at org.opensaml.xml.XMLConfigurator.load(XMLConfigurator.java:122)
 at org.opensaml.Configuration.init(Configuration.java:49)

opensaml needs log4j 1.2.13. I'm not too sure of what version of log4j JBOSS includes.

I also tried to include the log4j.1.2.13.jar in my WEB-INF/lib directory but I got the following error:

11:35:05,868 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.
11:35:05,868 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.spi.ErrorHandler" was loaded by

Can anyone please help me to find a solution to the problem ?
