Null pointer for axis2/tomcat example where the service interface/operation takes no parameters -----------------------------------------------------------------------------------------------
Key: TUSCANY-372 URL: http://issues.apache.org/jira/browse/TUSCANY-372 Project: Tuscany Type: Bug Components: Java SCA Axis Binding Versions: Java-M1 Environment: Fedora Core 5 Reporter: Simon Laws Priority: Minor This is based on a check out from last week so I will give it a go on the latest release but lest I forget the details. I have an example (attached) which simply calls a remote component via axis2/web services. The implemented operation takes no parameters and causes a null pointers exception down in the Axis code on the server side where the request message is being unpacked [1]. I copied the example and changed the operation signature to include a single string parameter (also included) and all was well. Nothing else, as far as I can tell, changed between the two versions of the sample.
