Apache XML-RPC Client for Java

[Janni Duerr]

Hi Everybody,

I'm having some trouble using the Bugzilla Webservice APIs with the Apache XML-RPC Client for Java.
Bugzilla with the extention Testopia is running perfectly on localhost on a win7 system and i managed to login and execute some methods like "Bug.get" via XML-RPC. Executing other methods always thows one and the same java.lang.ClassCastExeption though, and i can't figure out what the problem is.

Does anyone have an idea what is wrong? I thought it might be a problem with the method parameters but i can't fix it. The Java sourcecode is below.
Help is greatly apreciated.

Hello,

I'm having same problem. You able to resolve this?

I see this issue maybe in libraries. Since in debug mode this method
not returned values and show message error, do you understand me?
I changed Xerces library for Apache Xerces, and error messages now is
it:

If you have a solution, that's great.

[Luciano]

Hey Janni,

Try use this server like a test https://landfill.bugzilla.org/bugzilla-3.0-branch/xmlrpc.cgi
I tried and works, so that's problem maybe in my bugzilla server
configuration, ok?

[Janni Duerr]

Tried that.
I successfully connected to "http://landfill.bugzilla.org./testopia2/xml.rpc.cgi"  since i am trying to remotely call Testopia related methods too. I get the same ClassCastException as i described in the first email. So the configuration of my server shouldn't be the reason. Since the installed Bugzilla version on the landfill server is  3.0  instead of 3.2.5 as on my server. it helped me to find out that the Exception is thrown if you remotely call a method doesn't exist. the "Bug.get" method in 3.2.5 is named "Bug.get_bugs" in 3.0

But still, calling "TestCase.get" throws this Exception. I tried "Testopia.Testcase.get", "testcase.get" and others.

If anyone knows what the problem is, this should be fairly easy to solve.
Some help, please

-Janni

I solved the problem. For future reference:

Anyone encountering this ClassCastExeption make sure that the name of the method you are trying to call via XML-RPC is spelled correctly, including case sensivity and Bugzilla version differences. Also, when trying to call Testopia methods (or of other extentions i guess) the URL you tell your XML-RPC client to connect to might not the same as for Bugzilla methods.
i.e. where Bugzilla methods can be executed connecting to http://<yourServerURL>/xmlrpc.cgi , Testopia methods have to be executed connecting to http://<yourServerURL>/tr_xmlrpc.cgi
