Subject Re: Tomcat 4.0.3 Testing
Date Wed, 12 Jun 2002 12:03:17 GMT
Well, no dice moving to 4.0.4 beta3 or to 4.1.3 beta.
I've tested all of these, the classloader problem
still exists. (Note, I was able to get 4.0.4 beta3
Windows install to work but, as I deploy on Linux,
this isn't an option)

I did finally manage to figure out a spread of Jars
and classes to get it to work on any of them.  But,
bottom line, it would be a lot easier with consistent
logging!  It didnít help that Tomcat doesnít reliably
log errors either.  The very first that is need is a
try catch on the doGet and doPost that wraps the
entire method block, catches Throwable, logs it at
Error or Fatal levels and re-throws it.

Details I used to get it to work.

1)	Move the jaxrpc.jar to a higher level in the
classloaders such as common/lib or shared/lib.  This
is to get around the ClassNotFoundException on class
2)	Extract all the files from tt-bytecode.jar and
rebuild the jar.  This is to get around a
SecurityException package com.techtrader (Funny, Iím
not even running a SecurityManager)
3)	Extract the classes from jaxrpc.jar and put the
classes under WEB-INF/classes. This is to get around
the NoSuchMethodError (Yes, Error not Exception) on
the call in
org.apache.axis.deployment.wsdd.WSDDDeployment to
tm.setSupportedEncodings(new String[]
{encodingStyle}); tm is of type interface
org.apache.axis.encoding.TypeMapping which extends
javax.xml.rpc.encoding.TypeMapping.  The requirement
for the method setSupportedEncodings is in javax
version and Tomcat doesnít see it for some reason. 
Note, extracting these still requires the jaxrpc.jar
to be in a higher classloader, if you remove it the
Exception described in 1 reoccurs.

After I did this, it successfully ran on Tomcat 4.0.3
on Linux, 4.0.3 on Win2K, 4.0.4b3 on Win2k and 4.1.3b
on Win2k
