[JBoss Portal] - IPC - unable to get example to work
by JohnnyTheHun
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
