1-See on
http://www-106.ibm.com/developerworks/java/library/j-ejb1022.html
for pattern business delegate.
2-You must declare your EJB Local or remote or both interface in your
web.xml,
Like this foo example:
#ejb-ref
# ejb-ref-name
# ejb/fr.artal.FooHome
#/ejb-ref-name
#ejb-ref-type
# Session
#/ejb-ref-type
#home
# fr.artal.FooHome
#/home
#remote
# fr.artal.Foo
#/remote
#ejb-link
# FooEJB
#/ejb-link
# /ejb-ref
3-Call your delegate interface, in your action class:
import org.apache.struts.action.Action;
#Public class FooAction extends Action
#{
# //~ Static fields/initializers
-
#
# public static final String ID = ID;
# public static final String NAME = NAME;
#
# //~ Methods
# protected ActionForward execute(
# ActionMapping mapping,
# ActionForm form,
# HttpServletRequest request,
# HttpServletResponse response)
# throws Exception {
#
# Integer id = null;
# FooData fooData = null;
#
# if (form != null)
# {
# // using the form displayed in the view to get
the foo id
# String id =
(String)PropertyUtils.getSimpleProperty(form, id);
#
#
# // using business delegate pattern to interface
with EJB session
# FooDelegate FooDelegate = new FooDelegate();
#
#
# fooData = FooDelegate.getFoo(id);
# }
# if (fooData != null)
# {
# // set the request attribute
# String name = fooData .getName();
#
# request.setAttribute(ID, id);
# request.setAttribute(NAME, name);
# }
# }
#}
4- you can now, use the request object to display all the foo fields in
your view(JSP)
Example foo data:
#%@ taglib uri=/WEB-INF/struts-bean.tld prefix=bean %
#%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %
#
#html:html
#head/head
#body
#
#table width=500
# border=0 cellspacing=0 cellpadding=0
# tr
# tdFoo:/td
# /tr
# tr
# td Id: %= request.getAttribute(ID) %/td
# /tr
# tr
# tdnbsp;/td
# /tr
# tr
# td Name: %= request.getAttribute(NAME) %/td
# /tr
# tr
# tdnbsp;/td
# /tr
#/table
#/body
#/html:html

Need Help : DispatchAction and html:image without javascript.
Hello All, I request you to suggest solution for the following problem. I want to use LookupDispatchAction or DispatchAction class so that the framework can call my action class methods when user preses any button in the JSP page. If I use html:submit buttons the value (which is equal to method name) with it gets submitted and used to call appropriate method in the action class. I am using html:image for buttons. The problem with it is the value for these buttons doesn't get submitted and framework cannot understand the method name. Does that mean if I use html:image then I cannot use DispatchAction or LookupDispatchAction Class. Or If I want to use these classes then I cannot use graphical buttons? can anybody tell me how can I use these classes with html:image ? The main thing is, We don't want to use any peace of javascript code. Thanks in advance. Shashank S. Dixit Associate Software Consultant. Datamatics Ltd. SDF-1, SEEPZ, Andheri,Mumbai
Re: Need Help : DispatchAction and html:image without javascript.
Hello Martin Thanks for your help, I found out the code for ImageButtonDispatchAction and it would be useful for me. Regards, Shashank S. Dixit Associate Software Consultant. Datamatics Ltd. SDF-1, SEEPZ, Andheri,Mumbai - Original Message - From: Martin Naskovski To: Shashank Dixit Cc: Struts Users Mailing List Sent: Thursday, July 24, 2003 12:51 PM Subject: Re: Need Help : DispatchAction and html:image without javascript. Shashank, look for ImageButtonDispatchAction.java in the archives of 'struts-user'. The image buttons get submitted as property.x and property.y. Even if you didn't use the above named file that one of struts' users created, you can easily extend the DispatchAction (look at the source code for Struts on how to do this properly) to look through the HTTP ParameterMap, and look for parameters named *.x or *.y, either using regex or just parse them using the java tokenizer. You only need to find one, either .x or .y, to confirm a button push on the form. ImageButtonDispatchAction (already existing in the archives) already does this, except through the ActionMapping in struts-config.xml you specify what the button names on the form are in the 'parameter' attribute. Doing that, cuts down the time it'll take you to look through the HTTP parameter map. Hope this helps.

Re: Design question: Confirm action after validation ?
Hello Adam I have one doubt. You have base action class for all your subaction classes. What is the responsibility of this base action class. Do your base action class checks which button is clicked? If there are say 10 buttons in one form (say, GO, ADD, SAVE, NEXT, etc) are there 10 if statements in your class. Or it is sub action class resposibility to check this.? are there 10 or (any no) of if statements in subaction classes.? How to eliminate those if statements? any idea?

About Value Object
Hello All I am designing a framework using struts which involvs support for EJB too. I got one prob of sending value objects to app servr and taking it back. I am creating value objects from FORM beans and then sending it to AppServer.

Where is the place for it? If I want to retrieve value in JSP page in Html FORM then What is I create RESULT OBJECT as a part of FORM beans. Can anybody suggest something on this.

Re: site root going straight to a .do
Hi Simon We specify welcome file in web.xml file and not in struts-config.xml.

Subject: RE: Struts Validation Question
What does your action mapping look like in the struts-config? Also, I
believe, by the time you are in the action validation will already be
performed (once you have it working properly). So you don't have a call
to
validate() or anything to do with validation in the action.

Subject: Struts Validation Question
I've been trying to make validator work with our application. However,
I've
not been
very successful. Here is what I did. Please let me know if I missed
anything.
I've created a form with firstName and LastName fields. The validator
should
see if that the form is not empty. Howver, when I don't fill in and
submit,
I get
to the next page. I don't see the validator checking for errors and
reporting.
I followed the guidelines in http://www.onjava.com/lpt/a/2912
1) Put the commons-validator.jar,jakarta-oro.jar and the struts.jar in the
lib folder
2) Put the validator-rules.xml file in the web-inf directory.
3) created the validator.xml file in the web-inf directory and put the
following in the
validation.xml file:
form-validation
!-- == Default Language Form Definitions
=
--
formset
form name=com.gdm.form.FBOrder
field property=firstName
depends=required,minlength
arg0 key=orderForm.firstname.displayname/
arg1 name=minlength key=${var:minlength}
resource=false/
var
var-nameminLength/var-name
var-value5/var-value
/var
/field
/form
/formset
/form-validation
4) Created the ActionForm class and extended it from validator.form
5) Called the ((FBOrder)form).validate(..) method from the action class
6) Created the following code in struts-config.xml
plug-in className=org.apache.struts.validator.ValidatorPlugIn
set-property
property=pathnames vaue=/WEB-INF/validator-rules.xml,
/WEB-INF/validation.xml /
/plug-in
7) put the following code in the jsp page.
logic:messagesPresent
bean:message key=errors.header/
ul
html:messages id=error
libean:write name=error//li
/html:messages
/ulhr
/logic:messagesPresent
7) Put the following in the applicationresources.properties file.
button.cancel=Cancel
button.confirm=Confirm
button.reset=Reset
button.save=Save
# Errors
errors.footer=
errors.header=h3font color=redValidation Error/font/h3You must
correct the following error(s) before proceeding:
