Display tag is one of the best free open source libraries for showing data in tabular format in a J2EE application using jsp, struts or spring. Display tag is my favorite solution for displaying any tabular data because of its inherent capability on paging and sorting.

In this article, we will see some important points to note while using display tag in jsp. Though this library is very stable and rich in functionality still there are some subtle things which matter and if you don’t know you could potentially waste hours to fix those things.
These are the points I found out while I was using displaytag in my project and I have listed those down here for benefits of all. I have outlined all the examples based upon task I had to perform and due to those tasks, I discovered and get myself familiar with display tag. In many scenarios, we need to show two separate tables in one jsp page. We can do this by using two tags easily but the catch is that sorting will not work as expected.
When you sort one table, the second table will automatically sort or vice-versa. To make two tables independent of each other for functionality like exporting and sorting you need to provide “uid” attribute to table tag as shown below.
Display tag library – Displaytag tutorial
I ddisplaytag found this when I tutodial sorting issue on display tag. There was a bug in one of our jsp which shows data using displatag, with each paging request it was reloading data which was making it slow.
Then we thought to filter out displaytag paging request and upon looking the pattern of displaytag paging request we found that it always starts with “d-“, so by using this information you can filter out display tags paging request.
Since we were using spring it was even easier as shown in below. Many times we require reference of current row while rendering display tag data into a jsp page. In our case we need to get something from currentRow and then get Something from another Map whose key was value retrieved from current row, to implement this, of course, we some how need a reference of the current row in display tag. After looking tutoria, and displaytag. Name of variable would be the value of “id” attribute, this would be much clear by seeing below displayttag In Below example, I am showing date in “yyyy-MM-dd” format.
You can also implement your own table decorator or column decorator but I found displaygag option easy dis;laytag ready to use. Here is an example of a sortable column in display tag.
Some time we need to make a particular columns value as link may be to show another set of data related to that value. If you want to pass value as request parameter you can do that by using another attribute called “paramId”, which would become name of request parameter. Here is an example of making a link and passing the value as the request parameter in display tags.
Values on this column will appear as link and when user click on the link it will append a request parameter “symbol” e. If you want that your table data is by default sorted based upon a particular column when displayed then you need to defaine a column name displaytxg default sorting and an order e.
This will display table which would be sorted on the first column in descending order. This was the issue we found once we done with our displaytag jsp. That was not the desirable action for us.
Upon looking around we found that display tag by default sort only current page data dispalytag you can override this behavior by providing a displaytag. This was an important piece of information which we are not aware until we hit by above-mentioned the issue.
Later we found that we can use displaytag. Another good behavior we discoved was showing empty table if provided list is null or empty.
