One thing I shouldn’t skip is the controller for the search results page, the page within which we will build our table. Since only the item jjmesa is actually needed for our purpose, the implementation is simple: With this, no onClick method will be generated for the column header, preventing users from accidentally causing a mess.

With this, no filtering row or icons will be generated above the column header and the highlighting feature will be turned off. Post as a guest Name.

The key is in the variable resultswhich now holds the entire text of the table generated by the JMesa TableFacade when we called its render method. That’s all there is to it! Since the details of table creation are encapulated in a factory, this is uncluttered: Some code in the project has been refactored from the way it appears in the article.

This is not a JavaBean property method, so we cannot directly point the TableFacade at it. You should also take a look at the preference page if you want to change the default nmesa structure. I won’t bother with package declarations, imports, or code not relevant to the point at hand; the complete code is available for download in the form of an Eclipse project.

Putting It All Together We’ll refactor out reusable code once more in writing a Factory to encapsulate building our customized table, starting with an abstract class: Also, defaults rarely exercise every feature, and this one is no exception.

Over a million developers have joined DZone.

Another thing I noticed that DisplayTag lacked was that when the user decides to export the table into a CSV or Excel file, the user is only allowed to export the data on the screen and not the entire result passed to the name attribute on the display: But recently I discovered an open-source Java library called JMesa that provides another way.

Note that we’ve also left off the pk column as per requirements. Now that the apache commons BeanUtils 1.

This is just one more branch on the decision tree we saw in the previous controller: So how do we leverage Ajax to help us? I have recently fallen in like with Spring MVC and so will use tutoriao to build a simple site with a few pages.
