Betreff: Multi-threaded soap call issue.
Hello,
We have a web service running on IBM Websphere.
It seems to be working fine and multiple clients are able to access it. I
have a strange problem though.
When a multi-threaded client program invokes it (having around 50 threads
and making multiple calls on the same thread), then
sometimes I get a "java -- no signature match" exception. When i looks at
the input call, it seems to be that the parameters of 3 - 4
calls are present in the same call (the same parameters are repeated over
and over for the single call)
My question is this.
1. Does soap have some limitation with multi-threading?
2. Is there some setting i need to have in websphere to overcome this?
Please let me know. Any help would be appreciated.
Regards,
Srikanth
