Class loading issues with Cocoon 2.1.7 and WebLogic 8.1 SP4
I've tried to gather as much as I could from the mail archives and the
wiki, but I'm not having much success. The application is based on
Cocoon 2.1.7 and needs to run on WebLogic 8.1 SP4. I have the
following in web.xml:
<servlet-class>org.apache.cocoon.servlet.ParanoidCocoonServlet</servlet-class>
And the following in weblogic.xml:
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
I get the following from the server's stdout:
CLASSPATH=C:\oracle\jdbc\10.1.0.2.0\ojdbc14.jar;C:\jdk1.4.2\lib\tools.jar;C:\bea8\WEBLOG~1\server\lib\weblogic_sp.jar;C:\bea8\WEBLOG~1\server\lib\weblogic.jar;C:\bea8\WEBLOG~1\server\lib\webservices.jar
...
Cocoon: init
Cocoon: Adding class library
file:/C:/work/dotech/realnet/trunk/build/cocoon/webapp/WEB-INF/lib/activation.jar
...
Cocoon: Adding class library

Cocoon: Loading servlet class org.apache.cocoon.servlet.CocoonServlet
Cocoon: init
...
java.runtime.version = 1.4.2_08-b03
...
os.name = Windows XP
...
org.xml.sax.driver = weblogic.apache.xerces.parsers.SAXParser
org.xml.sax.parser = weblogic.xml.jaxp.RegistryParser
...
There didn't appear to be any "javax.xml.parsers.*" system properties
set. When I make an initial request to the app, I get the following
exception:
java.lang.RuntimeException: java.lang.ClassCastException

at org.apache.cocoon.servlet.ParanoidCocoonServlet.service(ParanoidCocoonServlet.java:316)
...
There are no JAXP-related JAR files installed in the endorsed dir.
Just for kicks, I tried running JRockit 1.4.2_05-b04 instead of Sun's
JVM and got a similar error:
java.lang.RuntimeException: java.lang.ClassCastException: inv1

at org.apache.cocoon.servlet.ParanoidCocoonServlet.service(Ljavax.servlet.ServletRequest;Ljavax.servlet.ServletResponse;)V(ParanoidCocoonServlet.java:316)
I'm about out of ideas at this point, so any suggestions are certainly
welcome. Thanks!

Hmmm, looking at the source code, you should be right, but my experience was different. Maybe, I got
it all wrong..
Sorry,

Hm, that's not really true though is it? It just tries to load a class
itself before delegating to its parent.

Hi,
Keep in mind that the ParanoidCocoonServlet is *really* paranoid. It simply doesn't load anything
that comes from outsite the web application. Make sure you have _all_ necesary jars in web-inf/lib/...
Cheers,
Geert
