Hello,
i have a problem throwing a custom exception in a web method - the stacktrace lead me to a NPE in
I use JBoss 4.2.2 GA and JBossWS 3.0.5 native.
In the web service class i defined 2 methods, which are just throwing a custom exception -
one method without parameters and one with 1 input parameter:
{code}
@Stateless
@WebService
@WebContext(contextRoot = ConfigConstants.CONTEXT_ROOT,
authMethod = ConfigConstants.AUTH_METHOD,
transportGuarantee = ConfigConstants.TRANSPORT_GUARANTEE,
secureWSDLAccess = ConfigConstants.SECURE_WSDL_ACCESS)
@SOAPBinding(style= SOAPBinding.Style.RPC)
@RolesAllowed({ConfigConstants.ROLE_USI_USER})
@SecurityDomain(ConfigConstants.SECURITY_DOMAIN)
public class TestServer
{
@WebMethod
@WebResult(name = "companyList")
public CompanyList getAvailabeCompanyList() throws SystemException
{
if(true) throw new SystemException("getAvailabeCompanyList ");
return null;
}
@WebMethod
@WebResult(name = "companyList2")
public CompanyList getAvailabeCompanyList2(
@WebParam(name = "str") String str
) throws SystemException
{
if(true) throw new SystemException("getAvailabeCompanyList2 " + str);
return null;
}
}
{code}
When i call the methods, the one with an input parameter (getAvailabeCompanyList2) correctly throws the exception,
but the method without input parameter fails with the following stacktrace:
{noformat}

{noformat}
instead of the custom exception.
For the other method, its the supposed one:
{noformat}

So here the questions:
- Do i have an error in the code ?
- Is this a bug ?
- If yes, is it known or even fixed ?
Any hint or solution is welcome.
Best regards,
Timo
