A Final Word

In this column we continued our series on Web services. In this column we practiced ideas and techniques we brought to you previously in this series. We showed you how to call (consume) the Add and IsPrime Web services with the DHTML webservice behavior. We explained how to implement the consumers on the same page, as well as separately. We described the details of each function call. Notice that we did not implement extensive error handling. You can find out how to handle errors in Column 105, Web Services, Part X: Consuming the StockQuote.

In this column you have learned:

• How to write a multiple-service consumer
• How to script a multiple-service consumer
• How to consume the Add Web service
• How to consume the IsPrime Web service

You can download all of the files shown here (add.html, isprime.html, and webservice.htc) directly from this zipped file.
