Cool, but have you seen the one posted by Joe on dwr mailing list a few time ago? It doesn't reload the page when you sort or filter data! ajax+dwr+Joe rulez;)

I spent yesterday trying some tests, in a few situations, putting an eXtremeComponents table in the same tile jsp's as a displaytag table, sharing the same collection. So far it appears that there are a few issues we have, with displaytag, that the eXtremeComponents table appears better on. One is the export filters and old WebLogic servers. For some reason, when a table is in a Tile, or just inserted by a jsp:include or even a RequestDispatcher.forward(), on an old WebLogic server where we have to deploy some external web applications, the displaytag ResponseOverrideFilter is prevented from working, by WebLogic. For some reason, when there is output from an included jsp in the response, it seems that WebLogic won't let the Filter get the Response and alter it. I think WebLogic is being too paranoid and disallowing something that is perfectly normal under j2ee (and I've seen other complaints around the web about pretty much the same thing, with no resolutions), servlet, jsp specs, but in the meantime we need a workaround. Previously we actually had to write extra jsp pages, to get around this. When a displaytag table, in a Tile, needed to provide exports, we had to disable the displaytag's actual "export" attribute, and instead provide a link to a version of the table, in a new jsp, that directly set the response content type (e.g. to Excel). Yet the ExportFilter of the eXtremeComponents table works fine in the exact same situation. I still haven't studied the code enough to see what the difference is. But in a test web app deployed on the old WebLogic server version, in a tile, with both a displaytag table and an eXtremeComponents table, with the export set to true for both tables, and both export Filters mapped to the test url, the displaytag one fails due to the filter response problem with WebLogic, but the eXtremeComponents export works fine. Also the eXtremeComponents offers PDF export out of the box, which is nice.

Something that neither the displaytag table nor the eXtremeComponents table appear to do out of the box, without some hacking, is:

Display a column of integer numbers, so that, say, 9 precedes 1000, and so 9 is formatted as "___9" (leading blanks, and/or right justified, whichever), but so that they are still integers internally, and if used as parameters on links, they go as the right integer values e.g. "9" and not "___9".

Seems that with displaytag we need to write a table filter and mess with comparators, or with eXtremeComponents we need to subclass the sorter and formatter (to mess with comparators) and provide them as "callbacks".

But with eXtremeComponents they do handle dates and currency out of the box, re correct sorting and formatting, so why not integers?

(perhaps because the underlying NumberFormat/DecimalFormat, in java.text, do not have a way of specifying an integer "format" string indicating right-justified with leading blanks, e.g. so given 9 and 1000, the 9 is formatted as "___9" to align with, and sort before, the "1000"?)

I created the eXtremeComponents, and I just wanted to say thanks for posting the eXtremeTable on your site. It is fun seeing my image posted somewhere else on the web. I also thought I would reply back to some of the posts.

I created eXtremeTable because I wanted a tag that was very customizable without sacrificing any performance. It took me a very long time and tons of refactoring, but I finally accomplished it and thought other people may enjoy it as well. The eXtremeTable is so flexible. If it does not do what you need you can just Implement the correct Interface and plug it in.

I never really thought about it, but I guess it does seem odd that this tag just kind of appeared out of nowhere. It has actually been in development for some time and for the people that have used it, it does not seem new at all. I only waited so long to tell other people because I wanted to be able to make it the best it could be. I have refactored and redesigned the eXtremeTable over and over getting to where I am completely happy with it. I guess that is a long way of saying that there is no fear of this becoming abandonware. I just wanted people to know that.

I also saw one person post that that the eXtremeTable has performance problems. I wish he would have elaborated because I encourage people to profile the tag and report their findings. The eXtremeTable is so lean and performs so well it barely shows up on a profiler.

Vicky raised a good point about having to use the count(*) to get the total row numbers when using the 'limit' feature. I'm still not sure what to call it, but I guess limit, or paging, or something like that is fitting. Anyway, the total is only used for display to the end user. In the eXtremeTable's terminology it is used in the View (HtmlView). In eXtremeTable views are pluggable so if you did not want to include the total then you would just have to modify the View and plug in your implementation. You can really make the eXtremeTable look however you want. Even with that though, after this next release, it is my plan to dissect the default View (HtmlView) and pull out what would be the common functionality between different potential views to make implementing your own custom table view even easier.

So, anyway, I sincerely hope people enjoy using the eXtremeTable as much as I have. It has been a lot of fun meeting and helping people at the eXtremeComponent forums!

I have been using the display tag for a while now and custom column functionality can be achieved using a table decorator. The decorator is very useful in getting things done. I used the table decorator to have check boxes displayed as a coloumn on the search result display table and tied the functionality of deleting the particular line item onclick. Its nice to have such tags and I will be trying extremetable, thanks Jeff for all your hardwork.

Yo estoy usando DisplayTag y he empezado a tener problemas cuando manejo las ventas de cada mes de un año, para alrededor de 13,000 articulos, matriz de 13,000 renglones * 14 columnas. Alguien ha usado eXtremeComponents para un volumen de datos similar con buenos resultados? I´m read english but no writing very well. Excuse me.

The link on sourceforge to eXtremeComponents is https://sourceforge.net/project/showfiles.php?group_id=108168.

Currently the http://extremecomponents.org site is down. My hosting company (http://lunarpages.com/) did not want me to use the Spring Framework anymore and just shut me down. I am pretty disgusted as I was not taking up any resources, and they just did it out of ignorance of what the Spring Framework is. I found a hosting company (http://eapps.com/) that I like even more and will be paying for a better plan. I get my own JVM and even have root access to my slice of the server. Unfortunately there is nothing I can do except wait for my account to be set up, the DNS to take effect, ect...

I have been working on some really nice changes the past week though. I plan on releasing another milestone this month that is more or less a code refactoring that will make working with the eXtremeTable even easier. Especially people using the Pagination feature are going to love the new way of interacting with the eXtremeTable!

Hi, Can anyone give me a full idea of how to implement extremecomponents using struts framework. Regards, Jyoti
