Environment: Apache Tomcat 5.0.24, JDK 1.4.2, Apache Axis 1.2RC3 I am using the ProxyService provided in the samples package as a starting point for implementing my own ProxyService class that would act as a proxy for web services. Using this design, I am able to connect to some services that happen to reside on the same axis server as the proxy service but having some issues when I try to connect to external services - e.g. http://www.xignite.com/xInsider.asmx?WSDL. Please note that the client seems to be working just fine (simply change binding address in the code to the endpoint URL) if I bypass the proxy. The exception I am getting indicates that its not even reaching the endpoint (note 404 error) - I did ensure that I am able to manually access the URL for both the service address as well as the WSDL file. Any pointers to resolving this issue is much appreciated.
I am first appending the exception I am getting and then the rest of my code. Thanks, -Arun **************************************************************************************** EXCEPTION
