Well for starters: Unless your persisting form objects, it really doesn't matter what type they are declared as. Typically you want this to be something the JSP/HTML can handle. I'd be curious to know what happens if you try to pass a value back for a Timestamp OR a Date object in an <html:hidden> tag. Bet it won't work...
What I think you care about is that your Business Object Model follows the iBatis guidelines. And as far as issue one goes, LA! (Youre preaching to the choir). You want those fields put into the objects youre going to throw into iBatis as easily as possible. If you can validate your DateStrings, BeanUtils can do the job with by registering the appropriate converter. My choice however is FormDef, precisely because of reason #1 (I use Hibernate with it) http://formdef.dev.java.net -----Original Message----- From: Mark Bennett [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 22, 2005 3:46 PM To: Struts Users Mailing List Subject: RE: java.util.Date vs java.sql.Timestamp 1) save typing: casting, try/catch blocks, library calls 2) using iBatis and following the adivice of Clinton Begin in the manual: * The use of java.sql.Timestamp is discouraged.

Usually the big deal is how it winds up in the business object and there are tools for that. FormDef does a really nice job, especially if you have to deal with international date formats. -----Original Message----- From: Mark Bennett [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 22, 2005 3:27 PM To: Struts Users Mailing List Subject: RE: java.util.Date vs java.sql.Timestamp Thanks for the reply, but unless I can get it to work with java.util.Date I will stick with the java.util.Timestamp because THIS DOES WORK implicitly without having to use SimpleDateFormat or any try/catch blocks. <html:hidden name="myBean" property="myRecord.myDate"/> <!-- modify with date picker tag --> public setMyDate(Timestamp myDate) { this.myDate = myDate; } public Timestamp getMyDate() { return this.myDate; } Using this I can round round trip the date as Timestamp using only basic getters and setters. But I would PREFER it was java.util.Date which I can't get to work.
