Calling a WebSphere Web Service over a Destination

Question

Hi there,
we have installed SAP CE 7.1 SP3 on machine1 and created a destination to another SAP server, called machine2, which we use as web space and save our WSDLs, e.g. machine2:50000/wsdl/MyService.wsdl.
MyService is a small dummy service created with WebSphere Service and works fine. It does not need any security details! This service runs on machine3 and its endpoint is machine3:9060/MyServiceWeb/services/MyServiceSOAP.
So I tried to invoke this service in the WSNavigator on machine1 by entering directly the url. This works.
But if I select the service over the logical destination and then try to invoke it, I get the following error message:
RemoteException: Invalid Response code (404). Server <http://machine2:50000/MyServiceWeb/services/MyServiceSOAP> returned message <Not Found>.
But the correct result is returned, too.
The definition of the destination is as following:
Type: WSDL
Name: MyService
URL: http://machine2:50000/wsdl/MyService.wsdl
System: Java
System Name:
Host Name:
Also a HTTP Authentication is entered with User ID/Password (Basic).
Another interesting point is that I found this error in the log file:
com.sap.engine.services.wssec.srt.protocols.AbstractSecurityProtocol # Authentication method is sapsp:HTTPBasic, but no user or password is specified.
But I can swear that this input is entered. The provided user has administrative rights for machine2.
I hope you can help me!
Thanks,
Felix

Hi Anthony,
If you are using a proper ssl certificate signed by one of the ssl certificate vendors, whose CAs are in the java root keystore, you donot need to do anything special.
However, if you are using a test ssl certificate generated within your organization, you would have to add it to the keystore of the JRE which runs the BPEL engine, otherwise you would usually get an error similar to "java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target". More information on adding the custom certificate to a JRE root keystore can be found in this article.
Hope this helps,
