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.

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: It provides color striping of table rows and onMouseOver row highlighting.

Of course, we need instances of this domain object. 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: Again, a single line of code will do all we need:.

The select we’ve already mentioned. Normally, we’d get them from a persistence expport for now, we’ll just create them explrt memory: Its getValue method is passed the item to be displayed, the property to be called, and the current row count.

JMesa requires JDK 1. The application-specific concrete class, after all this, can be pretty simple:. Since the details of table creation are encapulated in a factory, this is uncluttered: 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:. Per user request the javadocs are now online as well! Edit and Delete Columns Now we’ll add columns containing links to edit and delete pages for HelloWorld items.


Exporf not write for us? Expotr CoreContext has many uses; our immediate purpose for it is to retrieve a value configured in the jmesa. NET and Java programmers. Making a column actually, we need to have an HtmlColumn, ecport most columns qualify unsortable is very simple: The code to reorganize the toolbar is quite straightforward; while we’re at it, we need to include icons for the various output formats:.

The pages are not fancy, and I am going to skip most of the setup. 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. 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.

Each HelloWorld item produces a formatted string within its toString method. Isn’t that the sort of thing Ajax is supposed to help us avoid?

But it would be awfully nice if the images could be centered within the column, something notoriously difficult to achieve with CSS style sheets. It usually comes down to something like this:.

eexport But it’s the page we need. 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. One thing I shouldn’t skip is the controller for dxport search results page, the page within which we will build our table.


It’s still better than scriptlets or custom tag libraries both of which were, to be sure, phenomenal in their timebut it’s an undigestible mass, and even if I do step through it line by line and understand what it does, I’m still left with just a table.

In fact, we’ll learn even more if we put this page in a context. When this attribute is set, JMesa uses the Memento design pattern dxport save the state of its tables.

But recently I discovered an open-source Java library called JMesa that provides another way. Conclusion Now I don’t have to like tables: Of course, we’ll need a column into which to put the results. All that iterative logic simply looks incomprehensible to me. You can find out more by reading the recipestutorialsand examples. To fully customize this table is just as easy. Over a million developers have joined DZone.

Let’s start with some requirements: The table automagically paginates itself. There was a deprecated method JMesa was using that has now been removed in the lastest jQuery library. Tables typically present a lot of information in a compact space, making user overload a problem worthy of attention. We supply it with the set of items and with which JavaBean property of those items we want displayed in each column. The simplicity and unusual syntax of the latter code come courtesy of the jQuery Ajax library, which is thoughtfully used by JMesa: That’s really all there is to it!
