In my case, I got this Exception when I was trying to test the webservice by accessing the wsdl on the browser...
I am new to Webservice practicals...
I saw this in JBoss console log:
09:57:29,366 INFO [AxisService] WSDD published to: C:\jboss-4.0.3SP1\server\default\data\wsdl\project.ear\projectWeb.war\ProjectService.wsdd
09:57:29,382 INFO [AxisService] Web Service deployed: http://dell-ramba:8080/mlo/ProjectWS
So I tried placing the following URLs on the browser to access the wsdl
http://dell-ramba:8080/mlo/ProjectWS
http://dell-ramba:8080/mlo/ProjectWS.wsdl
Both failed. Second one gave the above mentioned exception...
Then my colleague asked me to try (a ? instead of .)
http://dell-ramba:8080/mlo/ProjectWS?wsdl
Then it brought me the wsdl xml....
