I know that it is probably a Websphere problem, but I'm hoping that perhaps someone
has come across this before:
When using log4j from a jsp, I have no problems. As soon as I use it from a servlet,
I get the following error:
java.lang.NoClassDefFoundError: org/apache/log4j/Category
Can anyone shed any light on why the jsp classloader has no problems, whilst the
servlet one does?
Thanks
Scott
