Hello all,
I ran into problems with Tomcat 5.5.9. We have xercesImpl.jar in
common/endorsed, and another jar (X-Hive's XML database's xhive.jar) in
common/lib, that includes a class that is put in the xerces package
(org.apache.xerces.dom) in order to access xerceses package protected
class ObjectFactory. This works as long as the classloader is the same
for both xerces and xhive.
With older tomcats this has been works fine for years now, but with
5.5.9 an IllegalAccessException is thrown.
I wrote a test case that seems to prove the case, or at least some
difference. Basically there are two classes, testing.A and testing.B. A
creates an instance of B and accesses a method that returns the
instances classloader.
When A is in common/lib/a.jar and B in common/lib/b.jar, both Tomcats
displays the same classloaders for A and B.
When A is in common/lib/a.jar and B in common/endorsed/b.jar, Tomcat
4.1.31 displays the same classloaders for both A and B, but Tomcat 5.5.9
displays a classloader for A but null for B.
The server with Tomcat 4.1.31 runs Sun's JDK 1.5.0-b64, the one with
Tomcat 5.5.9 runs Sun's JDK 1.5.0_04-b05. It is possible for me to
upgrade the other if you think this may be an issue. The classloaders
toString() output is actually different, come to think of it...
The test files are at
http://www.index.fi/indox/download/tomcat-classloader-test.tar so you
can easily see for yourselves.
