Web Services Deployment Issue, Liferay 5.2EE + Tomcat 6.0

[Alex Belt, modificado hace 11 años.]

Hi Everyone,

I'm developing a web service for our Liferay installation. I used the Service Builder to create the classes, and modified the interface as described here:
http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/Web+services+-+Manage+Users,+Organizations,+User+Groups,+and+Roles+via+SOAP

I've built the service and the wsdd and deployed the altered tunnel-web war file to the Tomcat server, and when I try to view the available services, I get this message:

[EXCEPTIONS:400] Exception:

The code I've written contains an addUser method, along with 3 other methods that I want to expose as a web service. I've verified the interfaces and various *Impl classes contain the method signatures, and the server-config.wsdd contains the method definitions. It's finding the definitions in the wsdd but not in the code. I've tried separately building the portal-impl and portal-service jars without any success.

Does anyone have any ideas what might be causing this error?

Thanks,
Alex


Edit: Found the problem - turned out there was a mismatch in the method names in the classes and the wsdd. Changed the casing and it works fine.
