376 Getting Started with IBM Data Studio for DB2 Only the maximum number of result sets returned is known, which forces Data Studio to assign a very generic result set definition represented by the anonymousResultSetType, as shown in Listing E.6. Listing E.6 – The anonymousResultSetType You can see the reference to the anonymousResultSetType in the XML schema definition for the PRODUCT_CATALOG stored procedure response message, as shown in Listing E.5. Listing E.5 – Reference to the anonymousResultSetType The generic result set information can cause problems with web service clients that rely on the message schema provided with the WSDL file – as you could see in Chapter 10 with the Web Services Explorer, where the result set content was not displayed correctly (Figure 10.25). Data Studio provides a way to circumvent this problem, but your stored procedure must match the criteria that it always returns the same number of result sets with the same metadata information for every possible invocation. If this is the case, you can add a more detailed result set XML schema. Follow these steps to add the additional result set information for thePRODUCT_CATALOG procedure: 1. From the Data Project Explorer, right-click the PRODUCT_CATALOG operation and select Edit to open the Edit Operation window. 2. Click Next to open the Generate XML Schema for Stored procedure page, then click Generate, as shown in Figure E.9.
Appendix E – Advanced topics for developing data web services 377 Figure E.9 – Generate XML schema for stored procedure 3. You will be prompted for input parameters in case the procedure has one or more input parameters defined. Use Irons as the value for thePRODUCT_TYPE parameter, as shown in Figure E.10. Figure E.10 – Provide stored procedure input parameter 4. Click Finish and re-deploy your web service. If compare the result from the Web Services Explorer shown in Figure E.11 with that shown in Figure 8.25, you can see that the response is now displayed correctly.
