tomcat 4.01 with jboss 2.4.4 and a webapplication using xalan/xerces
hi hi,
Even after reading the docs (
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html)
and mailing list archive (
http://marc.theaimsgroup.com/?l=tomcat-user&r=1&w=2)
I am still stuck with the following problem:
We are currently using jboss-2.4.4 with tomcat-3.2.3 and I am trying to
upgrade to tomcat 4.0.1 as we need its newer jsp features. Our
application is using jsp together with a custom xsl-tag-library based on
xalan/xerces. JBoss itself is using xerces as its xml-parser (for
configs) in our setup. I plugged it in using JAXP.
Now when I am trying to access any jsp which is using the xsl-taglibrary
(which uses xalan/xerces) under tomcat 4.0.1 I get:
-------------- snip ---------------
type Exception report
message Internal Server Error
description The server encountered an internal error (Internal Server
Error) that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Servlet.init() for servlet jsp threw
exception
...
root cause
java.lang.ClassCastException:
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
at
javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:103)
...
-------------- snip ---------------
I guess the issue is somehow related to the fact that jboss is not
starting tomcat separately but using it as an own service and thus
tomcat inherits the classpath. The classpath in turn contains
../lib/xml-apis.jar:../lib/xerces.jar:../lib/xalan.jar
I've read about the issuses with xerces and tried to copy the xerces.jar
included with tomcat 4.0.1 (size 1808883 bytes) over all location of
mine; still it happens.
Now I am running out of ideas.

My bet would be that you're running Tomcat on a JRE instead on a JDK, and it can't find the Java compiler (which is necessary for compiling JSPs).

Tomcat on QNX with the J9VM !
Posted by Thai DANG <th...@nextenso.com>.
Hi all
I tried to start TOMCAT with the J9VM (oti). All seems to work fine
(servlet, internal web server of Tomcat) except the JSP page. Did
someone experienced such trouble ?
Many thanks.

Hi again,
I did more tests and I am getting more and more sure that this is whats
called a bug (please enlighten me if I am wrong). I don't care which
xerces.jar tomcat is using, but if I have one in my
"<webapp>/WEB-INF/lib/" I definitely want to use this one (as written
below, I've even tried to use the same). As I am getting class cast
exceptions, I belived TCs classloader has some problem.
