XML Parsers and Classloading in Tomcat
Hi,
I am having terrible trouble getting Axis up and running. I *know* my
problem must be related to class loading in Tomcat, but I cannot for the
life of me figure out what is going on, so I hope somebody here can help me.
I am running Tomcat 3.3a on a Win2000 machine, and am attempting to use Axis
Beta 1. I have followed the installation instructions as follows:
1. Copied the Axis folder from the webapps folder of my Axis download into
the TOMCAT_HOME/webapps directory.
2. Downloaded the latest Xerces 2 distribution and copied xercesImpl.jar
and xmlParserAPIs.jar into the TOMCAT_HOME/webapps/axis/WEB-INF/lib/
directory.
The contents of my tomcat lib directories are as follows:
TOMCAT_HOME/lib/container: crimson.jar, facade22.jar, jasper.jar,
tomcat_modules.jar, tomcat_util.jar, xalan.jar
TOMCAT_HOME/lib/common: connector_util.jar, core_util.jar, etomcat.jar,
jasper-runtime.jar, servlet.jar, tomcat_core.jar
TOMCAT_HOME/lib/apps: EMPTY
When I start Tomcat and point my browser to
"http://127.0.0.1:8080/axis/servlet/AdminServlet" I get the following stack
trace:
java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet

I reckon the XML parsing classes are not loaded correctly somewhere, but I
dont know how to get around this - can anybody please help me??
Thanks already,

RE: XML Parsers and Classloading in Tomcat

Still no luck!
I got rid of the xercesImpl.jar and xercesParserAPIs.jar (from Xerces 2),
and went to get xerces.jar (from Xerces 1.4.4).
I tried running the same as before with xerces.jar in
TOMCAT_HOME/lib/common, with no joy - the same exception.
I also tried putting xerces.jar in the TOMCAT_HOME/webapps/axis/WEB-INF/lib
directory and still the same exception was thrown.
Is there a setting in tomcat or something like that I should be looking for?
Thanks for your help
J

Yes, I did not see the xerces.jar file anywhere in your listing of your
Tomcat lib/common directory. Also, make sure you are using the version of
xerces that is compatible with JAXP, as mentioned in the Axis installation
guide. I had the same error - "NoSuchMethodError" being thrown from within a
different place in Axis, but it was solved when I ensured that I was using
the latest Xerces jar file.
