9.3. ClassLoading VFS

These examples provide an implementation of the ClassLoaderPolicy that uses a JBoss Virtual File System project to load classes and resources. You can use this idea directly or in combination with a classloading framework.

Optionally, you can set up your modules inside the Microcontainer configuration.

Example 9.14. Classloading Module Deployer

<deployment xmlns="urn:jboss:bean-deployer:2.0">

  <classloader name="anys-classloader" xmlns="urn:jboss:classloader:1.0" import-all="true" domain="Anys" parent-domain="DefaultDomain">
    <capabilities>
      <package name="org.jboss.test.deployers.vfs.reflect.support.web"/>
    </capabilities>
    <root>${jboss.tests.url}</root>
  </classloader>

  <bean name="AnyServlet" class="org.jboss.test.deployers.vfs.reflect.support.web.AnyServlet">
    <classloader><inject bean="anys-classloader:0.0.0"/></classloader>
  </bean>

</deployment>

<deployment xmlns="urn:jboss:bean-deployer:2.0">

  <classloader name="anys-classloader" xmlns="urn:jboss:classloader:1.0" import-all="true" domain="Anys" parent-domain="DefaultDomain">
    <capabilities>
      <package name="org.jboss.test.deployers.vfs.reflect.support.web"/>
    </capabilities>
    <root>${jboss.tests.url}</root>
  </classloader>

  <bean name="AnyServlet" class="org.jboss.test.deployers.vfs.reflect.support.web.AnyServlet">
    <classloader><inject bean="anys-classloader:0.0.0"/></classloader>
  </bean>

</deployment>

The VFSClassLoaderFactory class transforms the XML deployer into a VFSClassLoaderPolicyModule, which then creates the actual ClassLoader instance. You can then directly use this new ClassLoader instance with your beans.

Note

VFSClassLoaderFactory extends ClassLoadingMetaData, so all examples pertaining to ClassLoadingMetaData apply in this case as well.
