Hi All,
This is probably not specific to Magnolia but thought someone here
might have seen it. I am working on a Magnolia 4.1 module running w/
JDK6 and Tomcat 6 that processes XML data from a remote source. Both
the author and public side get deployed to the same instance of Tomcat.
Suppose I startup Tomcat and access a page on the author side that
executes the XML code. Everything works great. Then, I request the
same page on the public side but this time I get an error:
...

Similarly, if I request the page first on the public side and second
on the author it works the first time and gives the same error the
second time. I think this has something to do with an XML library
conflict but am not an expert in any of this. First thing I tried was
removing the xerces JARs bundled with Magnolia. This broke Magnolia
activation. Next I removed the bundled xerces JARs and placed one
copy in Tomcat's lib directory. This seems to be working but I'm
wondering if I created some new problem that I haven't triggered yet.
Anyone else run into this or know what's going on?
Tom
