Hi Thad,
I have no experience with Weblogic in particular,
but it's a known phenomenon that servlet engines
sometimes botch up their custom classloaders,
especially with respect to loading non-class stuff
(i.e. resources, such as HTMLEntities.res) ... uh,
regardless of their reputation! :) You could try
moving the xerces.jar from your servlet lib
directory to the servlet engine's lib directory,
or vice versa if it's there already, so that it's
being loaded by another classloader instance. In
a pinch you could also try loading it as a Java
extension, i.e. from your JVM's lib/ext directory.
Cheers,
- Gulli

Subject: Xerces and WebLogic
We have an application that we have developed with Apache and Tomcat
(current versions 1.3.20 and 3.2.2 respectively). Among other things, the
application allows for querying a database and returning the result set in
XML, filterable with XSLT. We are using Xerces 1.4.2 and Xalan 1.2.3.
All works fine with Apache-Tomcat on Linux and Solaris; with IIS-Tomcat on
NT; and IIS-JRun 3.1 on NT. Based on a customer's request, I've been
trying it out with WebLogic 6.0 (SP2) on Solaris. In this environment,
Xerces fails.
The error I am seeing comes from inside Xerces when my servlet is
attempting to build the query result XML:
...
<Aug 6, 2001 3:32:42 PM EDT> <Error> <HTTP>
<[WebAppServletContext(4818707,emma3)] Servlet failed with Exception
java.lang.ExceptionInInitializerError: java.lang.RuntimeException: SER003
The resource [HTMLEntities.res] could not load: java.lang.RuntimeException:
SER003 The resource [HTMLEntities.res] could not be found.
HTMLEntities.res
HTMLEntities.res java.lang.RuntimeException: SER003 The resource
[HTMLEntities.res] could not be found.
HTMLEntities.res
at org.apache.xml.serialize.HTMLdtd.initialize(HTMLdtd.java:418)
at org.apache.xml.serialize.HTMLdtd.<clinit>(HTMLdtd.java:560)
at
org.apache.xml.serialize.HTMLSerializer.startElement(HTMLSerializer.java:529
)
...
I looking at the source code to HTMLdtd.java, it seems that
HTMLEntities.res is being requested correctly. HTMLEntities.res is in the
JAR file and certainly it works in enough environments that one would
expect it to work in WebLogic (*especially* given it's Rolls Royce
reputation).
Does anyone have any experience with WebLogic and Xerces? Any ideas how I
might resolve this problem or whom to turn to?
Thanks!
