Re: NullPointerException urgent!

Fri, 02 Apr 2004 08:38:10 -0800

Thank you.
This time, I tried to call to the method searchPerson with a pre-fixed value.(no change to pass null parameter)
But, sill have the error.
I believe that there have been no change in programs or others related to my web service.
There may be a change for others sharing a computer to modify some setting, I guess.
Thus, Is there other case for the NullPointerException?
Thanks for your help!

Hi there
 
From your stack trace it looks like the error is happening here:
 
OpenDBLPClient.OpenDBLPBindingStub.searchPerson(OpenDBLPBindingStub.java:484)
 
Do you call your web service directly from your JSP (through a service singleton)..
Check the stub and line number 484, to see if there, by chance, is some of the parameters to searchPerson method that can be null and is not handled..
 
This is, in my opinion, an application error, nothing Axis specific...Let me know your results.

Subject: NullPointerException urgent!

Hi,
I built a web service via Axis.
Current I got this error.
When I try the system a few days ago, it was okay.
But, now it gives me the error even though I didn't modify anything.
I am working on public computer which my collegues share so I am thinking that something is modified by others.
Anyway,
Could anyone tell me what can cause this NullPoninterException?
I will try anything if it is suspious.
Thank you!
