Calling external web service from within a web service

This example shows how to wirte a web service that calls another web service. Make sure that "http://www.mssoapinterop.org/asmx/simple.asmx?WSDL", is up and running before trying this sample.

Steps involved in writing this example:

Do clientgen on the external service and put the generated classes in to the WEB-INF/classes directory build.xml
Write backend java class for the web service - HelloWorldService.java
Write ant build file to compile and build the service. build.xml build-webss.xml
1. compile HelloWorldService.java to output/WEB-INF/classes
2. run autotype to generate the codecs for the non build in types
3. run source2wsdd to generate web-services.xml deployment file and WSL file
4. put the DD file in output/WEB-INF/ directory
5. run clientgen on the WSDL file to generate the client jar
6. jar up output directory as a war file
7. compile the client side code Main.java
8. deploy the applicaiton by copying the war file into the applications directory of the server
Follow the instructions here to build, run and test the service.
