[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: Issue with the JBoss HelloWorldIPC portlet
This is the portlet I threw together. There are many other pages and windows deployed.
Only the PageLinkWindow and its parent are printed. Exceptions are thrown for every other
node the code attempts to access, but they don't propogate into the portlet doView
method. They are just printed to console.
Output:: context
| -DemoPortal: portal
| --ipc: page
| ---PageLinkWindow: window
Portlet code:
import java.io.IOException;

| StringBuffer html = new StringBuffer();
|
| PortalNode baseNode = request.getPortalNode();
| while (baseNode.getParent() != null)
| baseNode = baseNode.getParent();
|
| list(html, baseNode);
| listchildren(html, baseNode, 1);
|
| response.getWriter().write(html.toString());
| }

pn.getChildren();
