[OT] Re: Displaying mulitpage results
By using good frameworks like iBATIS (which has great support for pagination and dynamic queries) and design patterns pertinent to the requirement, the code in the layers you can be kept to a minimum. The web application at workeffort.dev.java.net does all kinds of pagination, ordering sorting etc from the database. The methods for pagination in the struts actions is a few lines and the service layer method call is a one liner. There is no code bloat if you take the time to design the different layers appropriately. Now that I remember, I think one of the major pain points for doing paging/sorting at the DB level with Hibernate and Struts together was needing to make a second query with count(*) to figure out how many total rows/pages there are. If Hibernate gave you back a paginated results object that implemented Collection (and size() works), which I think iBATIS does, it would be cleaner. Lazy-paginated collections may require the open session in view pattern to actually fetch the results from within a JSP page. I'm not that fond of this personally (hangs onto db resources during potentially slow output rendering/transmission) but it seems to be the widespread accepted practice. -- Bill -- Bill Schneider Chief Architect Vecna Technologies 5004 Lehigh Rd., Suite B College Park, MD 20740 [EMAIL PROTECTED] t: 301-864-7253 x1140 f: 301-699-3180 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Displaying mulitpage results
Check out the datagrid library at http://jakarta.apache.org/taglibs/sandbox/doc/datagrid-doc/intro.html If all you are looking for is pagination, sorting and ordering from the database this is a good fit. It does not have all the bells and whistles displaytag has, but is a simple and clean implementation. The biggest issue I have with the stock displaytag is, you have to stick the whole query result somewhere (generally in the users session) to do pagination. A very bad idea in my opinion. It's not a bad idea, it's a tradeoff: if you want native DB pagination (e.g., limit/offset in PostgreSQL, TOP xx in SQL Server, etc.) you either have to couple your UI components directly to the database, or you have to handle pagination at each and every layer in a multi-tier design (Struts Actions, business logic/session beans, DAOs/entity home interfaces, etc.) Neither choice is particularly appealing for the common case. My feeling is that, if you can't afford to pull all the results into memory at once, pagination probably is not the right UI design anyway. How meaningful is it to allow the user to jump to page 87 of 439? You should look at pagination strictly as a UI construct, to optimize *client* side performance rather than server-side (i.e., to avoid scrolling and downloading long HTML over a possibly slow dialup link). Then, in exceptional cases, you can always break abstraction and couple your UI directly to the DB (with JSTL sql tags, for instance) for server-side performance tuning when you really need it. -- Bill -- Bill Schneider Chief Architect Vecna Technologies, Inc. 5004 Lehigh Road, Suite B College Park, MD 20740 [EMAIL PROTECTED] t: 301-864-7594 f: 301-699-3180 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Displaying mulitpage results - Néstor
Hello Néstor, I'm quite happy using your taglib. I got only one problem: How can I get an index for the rows which are created. In Struts you would have something like this: logic:iterate id=element name=hvaList indexId=index There I could easily tell which row some data belongs to by usign the index above. How can I do the same thing in Datagrid? cheers, Peter Néstor Boscán schrieb: Hi Antony 1) Expose two more variables to access first page and last page ( like nextUrlVar). You can use the pages variable and get the first and last page elements to get the first page and the last page. But It may be interesting to put two aditional variables. 2) A way to specify the maximum number of page links on the page. For example if a query returns 500 records and the page size is 10 instead of showing 50 page links, limit them to a certain number. With the pages variable you can use the data anyway you like.
