Utilizes Jmesa feature as an underlying mechanism so serves managing representation of data in tabular form, filter,sort, paginate, export your. – The Export represents the export type that the user invoked. What you need to do is check to see if an export is being done. If so then just let JMesa output to the response. There are no filters to set up. You can find out.

For instance to create an HTML table with every feature available can be accomplished in four lines of code: The results show only the j,esa containing Einstein’s name in the last name column. Per user request the javadocs are now online as well! Join the DZone community and get the full member experience. You will have noticed the images in the table toolbar. ImageCellEditor encapsulates the general process of setting up an image with a link, and includes a method that will let subclasses override the default processing of the link:.

We continue by introducing a more user-friendly value into the format column. JMesa now has Spring and Struts2 integration in the 2. We’ll also need a bit of new code in the jmeda results page in the project, this is actually a different search results page, as you, oh sharp-eyed reader, have already noticed: As similar questions get posted on the groups I will exoprt those questions and answers to the Recipes page.

The ability to customize is critical. Also, defaults rarely exercise every feature, and jmeea one is no exception. Developer Fusion – The global developer community for. Columns are typically sorted by property value, but we just added a column that corresponds to no property, that displays the output of the toString method.

It usually comes down to something like this:. One line that might pass by unnoticed in all this, however, is really quite something:. There will be edit and delete pages to link to, of course, but these are not of interest here and are completely trivial in the Eclipse project.


This is more or less a call to the community that want Maven support. Unfortunately, the HtmlCellRenderer sub-interface that comes with JMesa has no method for adding attributes.

When this attribute is set, JMesa uses the Memento design pattern to save the state of its tables. Making a column actually, we need to have an HtmlColumn, but most columns qualify unsortable is very simple: There is some support for Maven in that you can pull the jar from my site.

It was tested with Tomcat 6, but should work with any servlet container. Edit and Delete Columns Now we’ll add columns containing links to edit and delete pages exporr HelloWorld items. Since only the item itself is actually needed for our purpose, the implementation is simple:.

Just to be clear, while Spring dependency injection and utilities are woven into the code below, JMesa does not depend upon Spring. To see the live examples just download the example war file and place it in your servlet container.

Re: how can i do export? – Jeff Johnston – – MarkMail

Brought to you in partnership with Red Hat. The simplicity and unusual syntax of the latter code come courtesy of the jQuery Ajax library, which is thoughtfully used by JMesa: The controller, of course, needs to interpret this new request correctly.

Asynchronous and Event-Based Application Design. This has a lot of code note the abstract methodsin part because I know I usually want edit and delete columns.

Running the Table With JMesa

Many more lines of code will be needed to enable them to do jmeas things like paginating through long lists of items, sorting by column values, and the like. The select we’ve already mentioned. It would be great to have more Locales supported out of the box.

Don’t get me wrong: Putting It All Together We’ll refactor out reusable code once more in writing a Factory to encapsulate expirt our customized table, starting with an abstract class: What you will find here is a carefully thought out API that is very easy to use and can be modified for your own needs.

The application-specific concrete class, after all this, can be pretty simple:. Over a million developers have joined DZone.

With this, no filtering row or icons will be generated above the column header and the highlighting feature will be turned off. The table looks and acts just as it did, except now it refreshes without resubmitting the form each jmexa.

If your Locale is not currently supported you should consider taking some time to create a messages file and send it to me. Of course, this means that the getValue method of the ToStringCellEditor will always be passed a bogus property value, but since the editor doesn’t use it, that’s no problem. As complex as jmrsa might seem, it’s actually the easiest part of the process. For page organization, not so much. And every bit of this came for free: This makes the page cleaner, gives me more functionality out-of-box, and enables me to nix at least some of the languages I’d otherwise have to fuss with.

The pages are not fancy, and I am going to skip most of the setup. Making a column actually, we need to have an HtmlColumn, but most columns qualify unsortable is very exporr.

xeport If the user clicked on the nmesa of that column, he or she would wind up with a very ugly NullPointerException message.

JMesa is a dynamic HTML table that allows you to filter, sort, paginate, export and edit your data however you need to. 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. Since 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.

Another epxort we need before we can build a table is something to show in it. We’ll use a Spring MessageSource to supply something a little easier on the eyes at runtime.
