Running the Table With JMesa. Again, we implement the functionality for jmrsa as two classes, the first a generic decorator with an additional template method: OK, we played around with some of JMesa’s images and CSS style sheets to make it fit in with our color scheme, but that really shouldn’t count. What would work would be to use the align and valign attributes of the cell.

The Decorator and Template patterns, however, come jmeea the rescue. Ex;ort allows the user to change the number of rows displayed. What’s not to like? For instance to create an HTML table with every feature available can be accomplished in four lines of code:. When this attribute is set, JMesa uses the Memento design pattern to save the state of its tables. This is just one more branch on the decision tree we saw in the previous controller:.

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. Note that we’ve also left off the pk column as per requirements.

We’ll also need a bit of new code in the search results page in the project, this is actually a different search results page, as you, oh expodt reader, have already noticed:. With this, jmmesa filtering row or icons will be generated above the column header and the highlighting feature will be turned off. How can we do that?

We’ll use a Spring MessageSource to supply something a little easier on the eyes at runtime. The application-specific concrete class, after all this, can be pretty simple: Our tools We’ve got automatic conversion jmessa to convert C to VB.

TableFacade is going to send itself messages passed as parameters in the request more on xeport in a moment. Something to Display Another thing we need before we can build a table is jmesaa to show in it.

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: Creating tables with JMesa is very easy. As we have already seen, a CellEditor is needed to change a cell’s displayed value.

Making a column actually, we need to have an HtmlColumn, but most columns qualify unsortable is very simple:. 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. Also you can compress javascript and compress css and generate sql connection strings.

We’ll start with pretty much the simplest functionality we can:. All we need do is add an arbitrary value to the column properties list:. Its getValue method is passed the item to be displayed, the property to be called, and the current row count. But it’s the page we need. Normally, we’d get them from a persistence service; for now, we’ll just create them in memory: All that iterative logic simply looks incomprehensible to me. The pages are not fancy, and I am going to skip most of the setup.

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.

One more change in jmesa-servlet. 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. For instance to create an HTML table with every feature available can be accomplished in four lines of code: Users accustomed to active, Javascript-assisted widgets don’t respond to tables that just lie there.

Making a row we need an HtmlRow unfilterable and unhighlighted is just as simple as making a column unsortable:.

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

I just updated one of our internal sites to use the feature throughout and it occurred to me that this may be a hidden feature to many developers.

Note that we delegate the messy work of actually rendering the toolbar to the JMesa superclass. There will be edit and delete jemsa to link to, of course, but these are not of interest here and are completely trivial in the Eclipse project.

We continue by introducing a more user-friendly value into the format column. Source Code Commits User-Friendly Format Column We continue by introducing a more user-friendly value into the format column.
