the reason is that AXIS C++ client sends HTTP 1.1 request and support in clinet for chunked is then assumed by server (tomcat)::More Data......
Using the tcpmon application, I was able to grab all of the data being swapped between the client and server.
For some reason, Axis (server, java) returns the returns the response "chunked" for the C++ Client but not for the Java client.
POST /file_manager/services/EchoCaps HTTP/1.1
alek
I assume the delay is due to the connection not closing correctly. The C++ app probaly returns after the connection times out???
Again, any help is appreciated -Ben

Hello,
I've used the WSDL2Ws tool that ships with Axis C++ to create a simple client for a java webservice running on axis/tomcat. The webservice method takes a string as it's only argument and returns the same string but in upper case.
The c++ method that gets generated has an extra input parameter, has a return type of void, and doesn't seem to work.
I tried commenting out the line with the second "m_pCall->AddParameter.." statement. This improved things a bit. I can now see that a call is being made. I determined this with a System.out.println statement on the server which shows that the string is being passed from the c++ client to the webservice.
After that, the app just hangs for about 10 seconds and returns with the following message:
execution break m_MsgSize == 0, so return NULL Press any key to continue
Is Axis C++ interoperable with Axis Java?. Do I need to tweak the WSDL to get this to work?
If the WSDL2Ws tool isn't generating the proper c++ code, does anyone know where there is an example of a working c++ client that calls an echoString type of webservice that I can use as a template?
Any help would be greatly appreciated.
