drop down list
Hi all In a List box if particular option has to be selected(say the 3rd one in a list of 5). Normally selected word has to be placed inside the relevant option tag option selected . In struts the very first option shows as the selected one on the browser. But if you need to show the 3rd option as slelected in the list how do we do that in struts? thanks a lot in advance Mahesh -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

So for example, say the drop-down list is a choice between a, b and c, and the property is called 'choice', and you want c to be the default, then you just make sure that the default value of choice in your form bean is c. If you need me to clarify further, email me and I'll send you some code to show what I mean.

Re: Velocity-Tools / Struts

Design question on loading form data
Hello!
If i want to fill a form with data (from, say a database) before showing
it to the user: Can this be done in reset() method of the form, or should
it be in the perform() method of the action class?
I think that doing it in the reset() method produces the cleanest code.
This can be done in quite a dynamic way too, since the reset method has
access to the http request and the mapping. It can use these to get info
on what (if any) item to load from the database.
Short example:
---
I have an action called editOrder and a form called orderForm.
In the reset method of the form:
reset(mapping,request) {
// check mapping, the form might be used by other actions
// that don't want our little featue
if (mapping.getType.equals(editOrder) {
int orderId = request.getInt(orderId);
OrderData order = db.loadOrder(orderId);
this.orderName = order.getName();
this.orderSize = order.getSize();
// .. and so on
}
}
---
Any suggestions or thoughts around this way of doing things? Looks nice to
me,
but I'd sure like to know if there is something nasty that I've missed here.

It may be different than what you expect, but in my opinion it is original and will be useful. It is kinda like lab work. For example -- the first chapter is called a warm-up and asks the user some questions and asks the user to set up tomcat PostGreSQL etc. This is useful for me. For example -- I know java, tomcat, struts to a certain degree and the warmup makes sure I know a certain level before continuuing. However database stuff I have never had time for and so it became clear that in order to continue I would have to download some stuff and do some reading etc. It seems that as the chapters progress you get to learn a little bit more of the puzzle. I think it comes down to how you learn. I learn through application and not much through listening. I am not sure if this is true of everyone. So far I am impressed by this book and plan on using it to further my knowledge in areas I consider weak. It is different than every book out there that I know of however and so make take some adjustment. This is not an endorsement, just my 2 cents. Sandeep __ Do You Yahoo!?

Design Help Needed - Routing to common transformer JSP
I've figured out a pretty slick (I think) way to use XSL have one page that changes the look and feel of my entire application. Basically, I put all my XML JSP's in a pages directory - and all they really contain is title, heading, and form elements (populated by bean:write and html:form). All layout is controlled by a CSS stylesheet (I'm only supporting standards-compliant browsers - and client agrees ;). So my rough solution at this point is to route all requests for JSP's to a JSP (with the same name in the / directory). So I have a JSP Transformer for each JSP XML page. I'd like to just have one page that does the transformation. However, there's GOT to be an easier way. You would think it would be easy to create a URL-mapping for this - or something like that. I would like it would be easy to create a url-pattern of *.jsx that would route to a htmlTransform.jsp page. Is this the best way? I really like the idea of using JSP's to get messages and form values - seems pretty easy. If there is a way of using a servlet in place of the htmlTransform.jsp - that might be a good idea...

Re: Design question on loading form data
Subject: Re: Design question on loading form data
From: Vic Cekvenich [EMAIL PROTECTED]
===
Here is sample pseudo code illustrating for one approach in
action/perform. Call for the model bean to populate in the action's
perform. Maybe the code of that retrieval and anything else having to do
with data is in the model bean. I sometimes use the FormBean, with
getters and setters, and put a retrieve, update, insert, delete methods
in the bean, so model is in one place, should there be any bugs.
Also, you can create such a bean, and test it in just a normal servlet,
before putting it in Struts. You could also test or use that bean anyplace.
package app;
public class NameLstAct extends baseAct {
public ActionForward mperform( ActionMapping mapping,
ActionForm form,HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// if list
sf=(SearchFrm)session.getAttribute(SearchFrm); // get the arguments
String fn= sf.getFstName();
String ln= sf.getLstName();
NameLstFrm nl = new NameLstFrm(); // make the Form Bean
nl.dbCon(); // ask bean to get a connection from the pool
// get us a list of names; based on retrieval argments
nl.retrieve(fn,ln);
//obviously, the FormBean has the SQL command coded in the above method
nl.dbDisCon(); // we do not need the connection no more
return(mapping.findForward(nameLstPg));
// if save
// {nl.validate(); nl.update(); ... }
// if delete {nl.delete(); ...}
// if new/insert {nl.inset(); ...}
}// perform Act
} // end of code.
