Hi A Srivani,
I this is not a problem with tomcat, instead it is a problem with your
deployment.
You are putting commons-discovery.jar, and this JAR file is storing a
reference to the webapp classloader.
When the app is reloaded, the old webapp classloader gets invalidated,
and a new one is created.
but since you put the the JAR in shared/lib that instance doesn't get
reloaded, and is now holding a reference to the wrong classloader.
This is simple a deployment problem, the correct way to deploy it is to
have it in WEB-INF/lib or fix the commons-discovery code.

Hi Maarten,
Thanks for your reply. I tried by keeping axis.jar in common/lib
directory
of tomcat, but it didn't work for me. BTW, in my jdk library there is no
axis.jar. Could you please suggest me any other way of solving the
problem.
Thanks,
A Srivani.

he,
i had the same problem...what i did was removing axis.jar from my jdk
libary
directory and put it just in common/lib directory of tomcat (not in
WE-INF-lib). SO in fact its there once on my server, and then it works
great.

Hi there,
http://www.mail-archive.com/users@tomcat.apache.org/msg07773.html
I am facing similar problem as in above link.
In my webapplication axis is used to connect webservices. If the
axis.jaris
in WEB-INF/lib I can reload my app and everything is fine.
But when I moved axis.jar to CATALINA_HOME/shared/lib to shrink the size
of
my war file I get a NullPointerException (stack trace follows) when the
application has been reloaded and I try to connect to a service. The
application runs fine until I try to connect to a webservice. What could
be
the reason for this?
I surfed the forums related to the problem and found that some are
suggesting to make reloadable=true in server.xml.But it is not possible
for
me.
Thanks in advance.....
A Srivani.
