Source codes of my blog entries about Stripes framework written several years ago – hantsy/stripes-tutorial. and include a or a couple tags inside the header cell. It looks like something similar is being done here, in this tutorial about grouped columns. JMesa is a dynamic HTML table that allows you to filter, sort, paginate, export and edit You can find out more by reading the recipes, tutorials, and examples.

NET and Java programmers.
Installation instructions will be found at the end of this article. Tutorjal this is functionality I use a lot, let’s design it for reuse, refactoring out reusable code into one class, and code tailored to this project into another.
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. It would be great to have more Locales supported out of the box. Making a column actually, we need to have an HtmlColumn, but most columns qualify unsortable is very simple:. It provides color striping of table rows and onMouseOver row highlighting.
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.
Sreekanth Siripuram: JMESA Complete Example.
There are two parts to the solution: The results show only the row containing Einstein’s name in the last name column. And every bit of this came for free: OK, you have to include some JAR files in the library, but what did you expect, magic?
The select we’ve already mentioned. One line that might pass by unnoticed in all this, however, is really quite something:. This is basically how you would integrate Jmesa into your Stripes actionBeans. First, we’ll add a property to the messages. The whole thing seems so error-prone note to self: In the Ajax solution, it assembles parameters for the TableFacade class and sends a request for the HTML for table display, adding a parameter to indicate that it’s an Ajax request.
And the basic jsp file. The ability to customize is critical.
If the user clicked on the header of that column, he or she would wind up with a very ugly NullPointerException message. 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. To demonstrate, we’ll use the select at the top of the form to change the jmssa of rows displayed to 16, sort by first name ascending and last name descending by clicking on the first column header once and the second twiceand mouse over the third row to see the highlighting: This makes possible many amazing features.
On the very first page of the JMesa web site we find four lines of code that we can appropriate and refashion for a Spring controller: We’ll use a Spring MessageSource to supply something a little easier on the eyes at runtime.
I also released an updated war file as rutorial. When I dynamically build a jmesa table I get only jmeda header row using the bean properties label.
Quickly and easily gain access to the tools and information you need! DisplayTag was good for two out of three things I needed to solve. For instance to create an HTML table with every feature available can be accomplished in four lines of code: 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:.
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.
