RE: This hopefully is a simple question that has been dealt with
Have you looked at the validator that comes with struts 1.1 beta? You can look at validator.xml and validator-rules.xml in the blank application's WEB-INF. It's for input though, as opposed to output. I haven't heard of anything similar for output. -Original Message- From: Vladimir Levin [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 28, 2002 10:48 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: This hopefully is a simple question that has been dealt with I haven't found the solution I will use yet to solve this problem in my own project, so advice would definitely be helpful.

What is the best way to deal with this situation? I could of course maybe have my business logic return me a Collection of EmployeeForm beans instead and inside the EmployeeForm beans there would be methods like setBirthDateDate( Date date ) that would take a java.util.Date and format it into a String and then call the EmployeeForm setBrithDate( String date ).

Does this tag exist architecture [was] This hopefully is a simple question that has been dealt with
On Friday, March 29, 2002, 11:19:25 AM, Maturo, Larry wrote: ML We define a separate bean that mirrors our ML EmployeeBean, but has string fields. We then ML get a list of EmployeeBeans and manually convert ML them to a list of EmployeeStringBeans. :-) It's ML a pain, but it works. Note that we only populate ML the fields we actually plan on displaying, since ML it is pointless to populate the other fields. Thanks for your feedback Larry. (By the way nice job on that AthensGroup paper on Struts if you wrote it). Currently I already have an EmployeeForm bean (all String fields) and an EmployeeBean (Strings, ints, etc.). The business tier does the DB query and returns an ArrayList of EmployeeBeans. Now the question becomes what next in order to iterate through this list and display the EmployeeBean fields in a nice way (ie. proper date format, currency format, etc.) ?... I'm assuming from your reply that you might have extra logic somewhere that will take that ArrayList of EmployeeBeans and loop through the list and populate a new List of EmployeeForm beans. In this step calls will be made to make sure the Strings in each EmployeeForm object are correctly formatted. I see how this idea will work, although it seems a shame that you have a perfectly good ArrayList of Employee objects and now you are iterating through it just to populate another ArrayList of Employee objects with all String fields. Before I looked into Struts I didn't see the big deal of iterating though this list of regular EmployeeBean objects and then where formatting was needed just call my helper util class to change the format. For example: %= RickUtils.displayDateAsString( bean.getBirthDate() ) % I know, everyone says the above it bad because you now have scriplets in your JSP code. Still, though, this seems to make more sense to me than to going through the overhead of looping through possibly a large ArrayList of beans in order to just populate a similar ArrayList with just String fields. I suppose I will go the later route in order to maintain the Struts architecture of perfectly clean JSP pages. Being new to struts and new to using tags, would it be that difficult to create a tag that when passed a double it new to spit out a display in some currency format or if it received a Date it would display it in the proper format. I noticed there is a tag library out there for display dates, but ideally I would like one tag that would just pick up the datatype and if datatype is double display this way, if Date display this way. Does a tag library like the above already exist? Thanks again for your feedback. I'm posting this to the list as well for any other ideas. ML There is a utility in Struts to help with this, but ML I have never used it, since it always seemed like ML learning to use it was more work than doing it ML manually.
