exception while trying Axis Deployment Tutorial

[gaurav abbi]

hi all,
i'm following a tutorial
wss4j
to get some knowledge about wss4j.jar.
i've already installed axis on my tomcat and able to call the various services.
but when i follow the procedure mentioned here and try to invoke the client
i get the following error.

E:\gaurav\official\devlopment\webServices\wss4jLearning>java samples.stock.clien

i tried googling for this, but not able to find anything relevant.

please tell me if its some configuration issue as it seems to me or there's something else is wrong.

Adding to this, i also want to understand the way wss4j works in making web services secure as i'm going to use it in my project. any urls,tutorials or book names will be really helpful as i'm not able to get a clear picture of this.

The code 502 seems to be SC_BAD_GATEWAY - that says to me that either your address was bad or the service was not running and your SOAP message never got interpreted. I suspect all those client side exceptions were due to not getting a SOAP message back from the server.

The best thing to do now is use TCPMON or something similar to capture the actual text sent and retrieved - that usually results in an "AHA" moment.
