NullPointerException in RPCMessageReceiver

["Kumar, Lokesh" <lk...@informatica.com>]

Hi all,

 

I have trying to fix a web service that I generated using Eclipse
Service Archiver plug-in. Whenever I try to run the operations of my web
service, I see the following errors on my Apache geronimo's log where it
is deployed -

 

java.lang.NullPointerException

I found some related mail exchanges done in this group a while back -
http://marc.info/?l=axis-user&m=116248489917125&w=2 which made me
suspect that I am getting null pointer exception because the arguments
of my operation is an array of string. However, when I removed that
operation with another that takes only string or an int, I receive the
same error.

 

I would appreciate if someone could tell me where to look to debug this
issue.
