Axis and Tomcat - java.lang.NullPointerException

Hi there,
 
In my webapplication axis is used to connect webservices. If the
axis.jar is 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?

RE: Axis and Tomcat - java.lang.NullPointerException

Posted by Srivani Ausula <Sr...@Sun.COM>.
Assuming the problem could be at common-discovery I posted here. Getting some pointers from tomcat-users-list but the issue is not yet resolved.If I am able to solve the problem I would definitely post the solution.
 
Thanks,
A Srivani.

Of course, it could be a bug in commons-discovery as that dominates
the stack trace. Did you find a solution on the Axis list?

Re: Axis and Tomcat - java.lang.NullPointerException

Posted by Martin van den Bemt <ml...@mvdb.net>.
The lack of response is probably coming from the fact that this issue has nothing to do with 
commons, so it's better to ask this on the tomcat-user list or axis user list..

RE: Axis and Tomcat - java.lang.NullPointerException

Posted by Srivani Ausula <Sr...@Sun.COM>.
Hi,
 
Does anyone came across the below issue? 
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.
 
After debugging the tomcat source(org.apache.catalina.loader.WebAppClassLoader.java), found that when the application is redeployed, axis.jar is available but it is not able to load 'org.apache.axis.EngineConfigurationFactory' class which is invoked from org.apache.axis.Service' constructor to get AxisEngine. Thus resulting Null pointer Exception.
 
Any pointers to solve the problem?Is it possible not to package axis.jar with my application?
 
Thanks in advance......
 
- A Srivani.

Hi there,

In my webapplication axis is used to connect webservices. If the
axis.jar is 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?
