RE: design question
Hi! From here: http://displaytag.sourceforge.net/11/tut_sources.html --- cut --- From a db? Displaytag will never support retrieving data from a db directly. Displaytag is here to help you in displaying data, not to retrieve them. Anyway, there are a couple of easy methods to get records from a db and display them using displaytag: --- cut --- -Original Message- From: fea jabi [mailto:[EMAIL PROTECTED] Sent: Monday, January 30, 2006 7:29 PM To: user@struts.apache.org Subject: RE: design question can anyone help me understand this?

For each row in the table I created an Object. I am creating instances of this Object and making a List which is getting displayed in the JSP. I was told that instead of creating Object and creating instances, one can directly use the result set got from the DB and iterate thru it to fill the tables. Which one is more efficient way to do? Is the second approach better? if so why? Thanks. _ Express yourself instantly with MSN Messenger!

RE: using an action form if no input from page
Hi! I would say you can use ActionForm as a bean to pass values from your action to your JSP. AFAIK ActionForm is just a bean with some convenience methods. Andrey -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, January 27, 2006 10:50 PM To: user@struts.apache.org Subject: using an action form if no input from page My question concerns jsp pages that provide a read only view of data. In other words, there won't be a form submitted from the page. Is there a compelling reason to use an action form in these cases. I've just been using tags such as c:out with my own beans put in scope. I've noticed that some people use the ActionForm and jsp form tags to do this same data transfer. That's strikes me as using the forms not necessarily in the way they were meant to be. But I'll admit to not being entirely clear on what seems to be a simple topic, actionForms that is. Any recommendations, with pros and cons. ___ Join Excite! - http://www.excite.com The most personalized portal on the Web! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Dispatch Action Error
Hi! As I can see from your trace, you are using DispatchAction and in some moments wrong method name is passed to this action. In the trace you've presented the method name is empty. 1. Action[/notes] does not contain method named 2. java.lang.NoSuchMethodException: com.vrs.crm.actions.NotesAction.( See, no method name after dot? I would recommend to add debug info in getMethodName() method and log path to see what's actually coming.
