Q:

Spring WS unavailable upon requesting connection

I've got a Spring WS which I'm able to call successfully for 2 requests.  Here is the output: 
2011-07-20 18:25:33,743 DEBUG [org.springframework.ws.client.core. WebServiceTemplate] -    Opening [org.springframework.ws.transport.http. HttpUrlConnection@1696452] to         [http://mymachine:8080/test-service/HistoryService]

But when making a request call to a newly created method, I get an error that Service is not available, although the service is available for other (originally present) method calls.  The output is: 
2011-07-20 18:25:53,166 DEBUG [org.springframework.ws.client.core. WebServiceTemplate] - Opening [org.springframework.ws.transport.http. HttpUrlConnection@1f2e95f] to [http://mymachine:8080/test-service/HistoryService]

Please suggest.

Managed to get this issue resolved.  The problem was that the WAR file that I was deploying in the Tomcat (webapps folder) did not contain the latest code changes and the main project POM file.  
To include the MAVEN directories, in Eclipse IDE, 
Right click on the WS project --> Properties --> Java EE Module Dependencies --> check the Maven Dependencies checkbox.  Then rebuild your project and re-deploy the WAR file in Tomcat.  This will now include the POM file along with other MAVEN Dependencies.
