Visual Web Application and JPA

Today I want to point to a couple of articles Contributed by Winston Prakash, maintained by Beth Stearns about Visual Web Pack in NetBeans 6 and the more useful option to use JPA to bind component.
Now instead bind a table ind a DB with a VWP table component and edit directly to the DB you can obtain data as entities and put it in the visual table component.

Visual diff

Today, via the Core Dump neighbor I found meld.
I usually work with NetBeans or Eclipse. Both needs you have open one or more projects to compare its files. I was looking for a tool like the 'diff' command line tool but more user friendly.

I think meld is it (and it is included as a package in Ubuntu).

Coloring nodes

NetBeans brings platform developers a way to improve node labels using simplified subset of HTML tags.
You can see it in action here in the nodes API tutorial.

Supposing you have a subclass of Node or AbstractNode classes, the only thing you need to do is override the getHtmlDisplayName() method.

public String getHtmlDisplayName() {
String name;

if(updateState) {
name = "Name";
} else {
name = "RED Name";

return name;

This peace of code returns the name of the node depending on the 'updateState' attribute. If something is wrong then the name is rendered in red.

Also, the 'updateState' can change in any moment, then only you need to do is to fire that display node name has changed with:

fireDisplayNameChange(oldName, newName);

Take in account that the old and new names must be different. If not, the fire method won't have any effect.
