| /** |
| * WebAppMarshaller |
| * |
| * An implementation of the AbstractJBossMarshaller code that is just |
| * enough to provide a ContextClassResolver that will use the Thread Context Classloader |
| * in order to deserialize session attribute classes. |
| * |
| * This is necessary because the standard infinispan marshaller (GenericJBossMarshaller) uses the |
| * classloader of the loader that loaded itself. When using the infinispan module in Jetty, all of |
| * the infinispan classes will be on the container classpath. That means that the GenericJBossMarshaller |
| * returns the container classloader which is unable to load any webapp classes. This class ensures |
| * that it is always the webapp's classloader that will be used. |
| * |
| * In order to use this class, you should put a hotrod-client.properties file into the |
| * ${jetty.base}/resources directory that contains this line: |
| * |
| * infinispan.client.hotrod.marshaller=org.eclipse.jetty.session.infinispan.WebAppMarshaller |
| * |
| * You will also need to add the following lines to a context xml file for your webapp to |
| * permit the webapp's classloader to see the org.eclipse.jetty.session.infinispan classes for |
| * the deserialization to work correctly: |
| * |
| * <Call name="prependServerClass"> |
| * <Arg>-org.eclipse.jetty.session.infinispan.</Arg> |
| * </Call> |
