1. System Os: Win2000 (or XP) JAVA_HOME points to JDK 1.5 2. JBOSS: downloaded and unzipped: jboss-portal-2.6.2.GA-bundled.zip 3. The IPC example is from: http://anonsvn.jboss.org/repos/portletswap/portlets/2_4/bundles/HelloWorl... 4. running jboss with run.bat - 0.0.0.0 5. deployed (unmodified) helloworldipcportlet.sar into an unmodified server/default/deploy dir under JBOSS_HOME 6. The IPC tab appeared on my default portal 8. The HelloWorldPortletA on the IPC page was empty 9. Looking into the server log I saw that HelloWorldPortletA doView() throws a NullPointer 10. After modifing the HelloWorldPortletA.java code to write everthing it does immediately: | protected void doView(JBossRenderRequest req, JBossRenderResponse resp) throws IOException, PortletException | { | try | { | resp.setContentType("text/html"); | StringBuffer html = new StringBuffer(); | resp.getWriter().write("strinbuff created"); | // link to a page | html.append("<-- Page Linking --><br/>"); | PortalNode thisNode = req.getPortalNode().getParent(); // will return this Page as a node. | resp.getWriter().write("parent got: "+thisNode); | PortalNode linkToNode = thisNode.resolve("../default"); | resp.getWriter().write("linktonode resolved: "+linkToNode); | I observed that linkToNode is null. What can I do to make the example work? (I need IPC, is there any other way?) Thank you, John View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106945#...
