RE: NullPointerException in tcpmon

[Samir Shaikh]

try another port, 1234 might be unusable in your environment.. usually a
port number 8000+ is a better guess.

Subject: NullPointerException in tcpmon


Hi,

after running tcpmon without any problems for some weeks now, i am getting
this weird NPE. Can anyone help me tracing this? I dont know where to look
for.
This NPE is triggered after i say "add" in the first dialog. I defined port
1234
as "Listen Port#" and 127.0.0.1 and 8080 has Target.

I am using 1.4.2_02 and %AXISCLASSPATH% was supplied when calling tcpmon.

Thanks.
