The best approach is to use a database-specific extension (since paging is not part of SQL standard syntax). I use PostgreSQL which has very nice and easy paging support (using LIMIT and OFFSET keywords). I've tried to do it once before using Oracle but had some trouble (as I recall the rownum didn't work as intuitively as you would hope or expect). The fallback position is to load the whole resultset into memory and store it as a session variable. This is a bad practice if the resultset can be large (a thousand rows or more for example).

Re: Struts design advice requested please.
Not enough detail for a full opinon, but this type of app is what EJB's are designed to handle at the EIS layer of the J2EE architecture. HTH - Original Message - From: Alex Colic [EMAIL PROTECTED] To: Struts [EMAIL PROTECTED] Sent: Thursday, January 10, 2002 9:20 AM Subject: Struts design advice requested please. Hi, I have been using Struts now for about a year and I really like it. It has saved me a lot of time and made my apps quite stable. I have just been placed on another large struts project. It will be pushing struts to the limit. A quick question on design. What I am going to do is a bit difficult to explain. This app is going to be used by users to input inventory data into two different databases, an AS400 and an Oracle/SQL database. The user will enter essentially the same type of inventory data into each system, but, there are differences between the two. Part of the project plan is that through a config switch, parameter etc, I will be telling struts if we are working with an AS400 system or an Oracle/SQL system and then the guy will slightly change, just the addition or deletion of a gui element. Example of required elements entered by the users in a form. AS400 ORACLE/SQL employeeID employeeID storeroom storeroom location location location type bin Number My question revolves around the form bean. I though about making a form bean that includes all the properties that are required by the Inventory object for the AS400 and the ORACLE/SQL system. This would make one large generic form bean. Then I thought about making an abstract class that includes all the common elements amongst the object and from there I would extend and create an AS400 inventory form or an Oracle/SQL inventory form. If I go this way then how do I set up the Struts.xml file to use the specific inventory form, if it could be one of two? I hope what I am trying to convey is making sense. Depending on a config setting I think I should be using one of two form beans, not known until run time. Any help in setting up the above is appreciated.

Re: Misunderstood newbie
To implement a screen of the particular Use Case, the following artifacts should be created: 1.Action class handles logic of that particular screen, errors and, probably, validation. 2.ActionForm class stores and validates the data presented on the screen. 3.BusinessDelegate class is responsible for finding and performing inter-tier method call of the Stateless Session EJB façade object that resides on the business tier. The value objects facilitate the interaction between BusinessDelegate and UseCase Façade. See the description of Business Delegate pattern at http://developer.java.sun.com/developer/restricted/patterns/BusinessDelegate .html. See the description of ValueObject pattern at http://developer.java.sun.com/developer/restricted/patterns/ValueObject.html . 4.Use Case Façade is Stateless Session EJB, which sits on the business tier and implements system-wise business methods that perform the logic of Use Case. See the Session Façade pattern at http://developer.java.sun.com/developer/restricted/patterns/SessionFacade.ht ml 5.JSP Page represents view in the MVC pattern. It should contain only HTML code and all the logic should be encapsulated into the Struts JSP Tags.

I made a very minimal example maybe you can figure out with

I just have to jsps and one Action the link on the first jsp
fires the action, which simply forwards to the second jsp.
I deploy with the command:
silvercmd deploywar localhost eTest TestWar.war -f deployWAR.xml

Deployment looks good and there are no exceptions. :-)
Afterwards i go to:

So far so good .. i can see the Link and if i move my mouse over
the link i see in the statusbar that:
http://localhost/eTest/testapp/testAction.do
is to be fired ok i do it and then ..
1. IExplorer : Error 400 Bad Request
2. Netscape: Invalid path /testAction was requested
Maybe it´s a bug in the Ag373 version?
ok . Thanks in advance if you find the time to look at my problem

I was referring to the struts example application, the one that comes with struts. Not your test application! If you cannot get it to work, you are deploying it improperly or you have a DTD access problem as Jeff mentioned. Once you have take the small step of getting the example app the one with struts to work you should be able to see by comparison why your test app does not work.

RE: Help with Struts and EJBS..
1) No, but it will work. Look at previous posts on how to properly
implement.
2) Your form should have get and set methods?
3) Collection
4) None that I am aware of.

Subject: Help with Struts and EJBS..
Hi,
I need some serious help.
I am a novice Java and Struts developer.
I am trying to develope a prototype that will work with backend EJBS..
I have an CustomerSearchForm, Form bean and action bean
my Action class is below.
Questions?
1) Is this the appropriate way to call EJBS (in an action class)??
2) How do I get what is returned from the EJB back into my actionform bean?
3) If I want a list of matching customers retruned...what is the best format
for these to be returned from the EJB so that I can
forward to another jsp and show them.. Currently the EJB is returning a
string.
4) Is there any sample applications out there that I can look at that use
EJBs?
Thanks in advance for ANY help.
Beth.
public ActionForward perform
(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
{
ActionForward fwdAction = null;
CustomerSearchForm searchForm = (CustomerSearchForm) form;
try {
// Get an InitialContext
Properties initProps = new Properties();
initProps.put (Context.INITIAL_CONTEXT_FACTORY,
weblogic.jndi.WLInitialContextFactory);
initProps.put(Context.PROVIDER_URL,
t3://yshen:7001);
Context ctx = new InitialContext(initProps);
Object home = (CustomerFacadeHome)
ctx.lookup(sov/CustomerFacade);
CustomerFacadeHome customerFacadeHome = (CustomerFacadeHome)
PortableRemoteObject.narrow
(home, CustomerFacadeHome.class);
CustomerFacade facade = (CustomerFacade)
PortableRemoteObject.narrow
(customerFacadeHome.create(), CustomerFacade.class);
String[] found = facade.findCustomer
(searchForm.getCustomerName (),
searchForm.getSsn (), searchForm.getAlphaKey (),
searchForm.getBank ());
for (int i=0; ifound.length; i++) {
System.out.println (\t[ + i + ]\t + found[i]);
}
fwdAction = mapping.findForward (success);
} catch (Exception e) {
e.printStackTrace ();

McClanahan Sent: None To: [EMAIL PROTECTED] Subject: RE: STRUTS and EJB On Thu, 23 Aug 2001, Juha Paananen wrote: I also agree on that stuff that has references to STRUTS should not be transmitted to the EJB level. The problem here is simply that I would not want to make another, exactly similar (except extends ActionForm), class for transporting the information to the EJB. Of course, I can do that, but I don't like the idea. My question is, is this inheritance of ActionForm really necessary in Struts design? Yes, it is ... and it is designed precisely to keep you from doing what you're trying to do :-). More seriously, an ActionForm exists primarily to save the server-side state of an HTML input form, in a fashion that it can be reproduced *exactly* the way the user entered it even if they make mistakes. For that reason, you will typically use String properties in an ActionForm, even for integer and date properties in the underlying EJBs. Further, the properties that exist on an ActionForm should match what is on the HTML form, which is *not* always (or even often, in my experience) exactly the same as the contents of a particular value object from a particular EJB. Think of an ActionForm as part of the view layer (in MVC terms), while a value object is part of the model layer, and it will make a lot more sense. Craig McClanahan
