Webservice with Oracle Weblogic 10.rG3 error with boolean and integer

I'm doing a few tests in weblogic to create webservices. Everything was ok, until I tried to add an Integer and a Boolean variable.

When trying to test my webservice via weblogic server, the following error appears:

[Server CodecHandler] Failed to encode fault -> beans.controls.imoveis.impl.ImovelImpl.setVagagaragem(java.lang.Boolean)

I had "solved" the Integer problem, by changing variables and database types to String. Since that isn't what I want, I tried solving this issu开发者_StackOverflow中文版e, though, with no success. In my service's xsd, the types are set as xs:boolean and xs:int. In Postgres database, it's the same, Boolean and Integer for columns types. I tried a few changes, but no matter what I do, I keep getting this error.

Does anybody knows what is happening here?
