RE: Please help... (EJBs and Log4j)

Hi Gareth,

 

Maybe you're running into ClassLoader problems. J2EE product vendors often have

multiple classloaders at work (esp. if they support servlets and dynamic reloading like

BEA's WebLogic). Careful attention to classpaths usually fixes most problems.

 

If you're using BEA's products see the FAQs and newgroup archives online

online (search for ClassLoader).

Subject: Please help... (EJBs and Log4j)

Hi all,

 

    I have been using Log4j for a short while and have now started to introduce it to my EJB development however I am getting an exception when calling PropertyConfigurator with a property file loaded from the system. Here's the exception I'm getting:

 

log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable to a "org.apache.log4j.Appender" object.
Exception: org.apache.log4j.RollingFileAppender
java.lang.ClassCastException: org.apache.log4j.RollingFileAppender
 at org.apache.log4j.PropertyConfigurator.parseAppender(PropertyConfigurator.java:574)
 at org.apache.log4j.PropertyConfigurator.parseCategory(PropertyConfigurator.java:555)
 at org.apache.log4j.PropertyConfigurator.configureRootCategory(PropertyConfigurator.java:462)
 at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:388)
 at org.apache.log4j.PropertyConfigurator.configure(PropertyConfigurator.java:332)

 

The property file is being loaded ok, but as soon as the property object if passed to the PropertyConfigurator it bombs with the above exception.

The same code works fine outside of an EJB. Has anybody used log4j with EJBs and can help.

 

Thanks in advance.

 

Best Regards,

 

Gareth Powell
