Adding custom Window Property

[d.haslinger]

Hello!

I've written a custom portlet that displays the content of an html file from the filesystem.
The location of this file is set by a custom property called "content", which value contains the path to the html file.

Currently I'm setting this property manually directly in the portal.

In the doView() method of the portlet, i receive the properties with:

PortalNode node = Navigation.getCurrentNode();
Map props = node.getProperties();

This works fine, but the problem is that I do not want to add the content property manually each time, I want to add it directly in the code, like:

PortalNode node = Navigation.getCurrentNode();
Map props = node.getProperties();

if(!props.containsKey("content")){
 props.put("content", "/html/file.html");
}

But this throws a java.lang.UnsupportedOperationException.

Can any one please help me with this?

Thanks a lot in advance,
Daniel

Tho code to retrieve the window properties does not need an active UserTransaction but the code to write them does.

Your options:

1. You can configure in jboss-portlet that your portlet need a transaction and then JBP will always wrap your portlet code in a transaction.

2. Lookup and begin a UserTransaction on your own exactly when you need it

the second is preferable.
