This page addresses issues commonly encountered, while invoking a web service at runtime. Keep in mind that those issues might be also relevant when invoking web services through WS Navigator, so it is worth looking into them as well:
- The call times out
- Check if the issue is in the Web Service itself, but not in the Web Service Client
- What means "SoapFaultCode:1" error message?
- You get an exception: Logical Target sap.com/DynamicWSProxies/ABC not mapped to a physical system (SAP NetWeaver 2004 and 7.0x only)
- You get an exception: Peer certificate rejected by ChainVerifier
- The call fails due to the port number of the endpoint equals -1
- What to do if I get the exception "Cannot connect to hostname"
