In the following steps you will be creating and/or configuring Spring beans in a Spring context file. A basic knowledge of Spring and the Spring Framework is required.

To complete the following task, you will need the following beans:

A XML schema filterbean for the applicable document types.
A link definitionbean for each of the link types to extract.

Open or create a new Spring context file.

Create an XLink extractorbean. Reference an existing XML schema filterto specify the document types for which the extractor applies.

<bean id="xhtml.xlink.extractor" parent="xlink.rdf.extractor.link.abstract">
  <property name="xmlSchemaFilter" ref="samples.dtd.xhtml" />
  <property name="linkDefinitions">
    <list>
      <ref bean="xhtml.linkDefinition.href" />
      <ref bean="xhtml.linkDefinition.img" />
    </list>
  </property>
</bean>

Restart the application server for your changes to take effect.
