Pragmatic approach to Java EE WebService.

• Make sure all WebServices you expose confirms to WS-I Basic profile guidelines.
• How do I make sure my WebService is WS-I Basic profile compliant?
• Read "Basic Profile 1.1 Test Assertions".
• Use a test tool like "WS-I Analyze WSDL" in Oracle JDeveloper to test your WSDL before publishing it.
• Use only "document/literal wrapper" style for your WebServices.
• Do not define your types inline in the WSDL, always define it externally and import it in the WSDL.
• Faults are important part of your service definition so always define meaningful faults for every operation.
• Do not define fault types inline in the WSDL, always define faults externally and import it in the WSDL.
