Let’s start with some requirements: We continue by introducing a more user-friendly value into the format column. This is our opportunity to introduce CoreContext and WebContext, two important classes that plug our code into the JMesa infrastructure. Since this is functionality I use a lot, let’s design it for reuse, refactoring out reusable code jmeza one class, and code tailored to this project into another.

Now I don’t have to like tables: Running the Table With JMesa. It provides color striping of table rows and onMouseOver row highlighting. The JMesa default is astounding, but no default is ever exactly like you want it. Isn’t that the sort of thing Ajax is supposed to help us avoid?

If it is exported, the results will be written directly to the output stream of the response; if not, they’ll be rendered as a string containing our HTML table:. Installing the Eclipse project is not difficult; the included Ant build file and these instructions assume Tomcat as the deployment target I’m using version 6.

This makes possible many amazing features.

Fiuxed Fixed a bug with the DroplistFilterEditor would not use the filter label, but nmesa uses the value. In fact, we’ll learn even more if we put this page in a context.

Before we can get to JMesa, though, we’ll need a few things: Don’t get me wrong: Creating tables with JMesa is very easy.
