Does the servlet could exist with axis???

[Bo1]

I made a servlet using Lucent MiLife to report the subscriber's
position and using MS mappoint to query and return map. When I test
the servlet separately: firstly I test the servlet with only Luncent
MiLife---it works very well
secondly I make a applet to test the mappoint code---it also works
very well
Then I integrate the mappoint codes to the servlet---but it generate a
lot of errors as follow:

I posted this problem to mappoint newsgroup, but I get a reply that
this problem might be relative with axis/soap. Is there conflict
between servlet and axis? How to solve these errors?
Thanks!

Just an idea:
I had a similar problem (not with MiLife...) when using two different XML
parsers in the tomcat. If you use e.g. Xerces in your HelloWorld servlet
(stored in <catalina-home>/webapps/HelloWorld/Web-Inf/lib) then Xerces is
loaded first. The exception says that Axis is started with Crimson as XML
parser (usually stored in <catalina-home>/common/endorsed)
In my projects I replaced the jars in the endorsed folder and everything
worked well after that.
