262 The XML Files: Development of XML/XSL Applications Using WebSphere Studio
11.3 Developing the customer registration sample
We are going to reuse customer registration sample code that we developed in
previous chapter. In order to develop this application, modify CustomerXSL
servlet and XSLs:
Re-generate all related files from customer bean.
Modify the CustomerXSL servlet to allow storage and retrieval of customer
data.
11.3.1 Adding the libraries to the project
You need to add two libraries to your project. Use the property window of the
project. Two variables are defined in Application Developer. To add the jars to the
classpath, use add variable button, and add XMLTOSQL and SQLTOXML. For
your information, the jars are located under the following directories:
XMLToSQL plugins\com.ibm.etools.sqltoxml_5.0.0\jars\xmltosql.jar
SQLToXML plugins\com.ibm.etools.sqltoxml_5.0.0\jars\sqltoxml.jar
11.3.2 XML Document format
One thing to be aware of is that the XML format is not compatible with our
customerXSL. The following XML is a sample that the libraries accept:
<SQLResult>
<Customer>
<firstname>firstname</firstname>
<lastname>lastname</lastname>
<email>email</email>
<membership>membership</membership>
</Customer>
</SQLResult>
The document root is typically SQLResult. And the first child, in this case,
Customer, is used as a table name, afterwards each column should follow
(Figure 11-6).
