How to get started ?
Hi All! I have been trying to get something going with Struts, but am having no go. I am not an expert @ JSP/Servlets but am decent at programming in Java. I have written a few servlets and am getting started with JSP. All the same, I want to get something going with STRUTS. I have seen the doco on the website, but it's not helping me much. I want to see an example of a SIMPLE MVC app where someone can point and say "That's the MODEL, that's the VIEW and that's the CONTROLLER". I understand that I may lack some fundamental knowledge, but can someone please point me to a good starting point ?

RE: ejb's and tomcat
Hi Ajay ! Apache Tomcat does not include an EJB container. You may want to try OpenEJB Container System (http://www.openejb.org) as a plugin to Tomcat and deploy EJBs. Another option would be to use JBoss(http://www.jboss.org) which includes the EJB Container.

RE: ejb's and tomcat
Hi Andrew, Mark, and ALL! The CMP2.x spec allows declaring EJBs as local objects. The advantage of the local EJB objects is that they don't get serialized/deserialized(I think) and pass-by-reference and not by-value. Effectively, If you use a LocalEJB, you have the flexibitly of making the REMOTE with very few changes to code. People, please correct me if I am wrong. Kunal -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED] Sent: Wednesday, 8 October 2003 21:20 To: Struts Users Mailing List Subject: RE: ejb's and tomcat Nonsense! In the same way acronyms look great on resumes, they also look just super on product brochures. If you use EJBs you can proudly proclaim that your application is "based on J2EE EJB technology"! This is useful for impressing clueless manager types even if EJBs confer no actual technical advantage (and often many disadvantages) to what your trying to do. btw: afaik its not just distributed stuff but also transaction type stuff its good for (but lets face it - most dbs do enough in that regards for most apps transaction needs already) -Original Message- From: Mark Galbreath [mailto:[EMAIL PROTECTED] Sent: Wednesday, 8 October 2003 19:04 To: Struts Users Mailing List Subject: RE: ejb's and tomcat If you are asking these questions, you probably should not be using EJB. The ONLY reason to use EJB is if you are developing a distributed application; anything else is overkill. If you simply need data persistence, use JDBC and use DAO, or one of the persistence frameworks: Ibatus, Hibernate, or Kodo-JDO.

HOW and WHERE do I call my EJB from
Hi All !
I am trying to start out with struts.
I have successfully deployed an EJB in JBOSS and want to call it from my
Struts-based web app.
My current setup:
ActionForm: GetSearchCriteriaForm extends
org.apache.struts.action.ActionForm
Action: SearchAction extends org.apache.struts.action.Action
SearchAction.execute( ... )
{
String vehicleID =
((au.com.carsales.carsales.GetSearchCriteriaForm)form).getVehicleID();
request.setAttribute( "vehicleID", vehicleID );
return( mapping.findForward("searchUsedCars" ) );
}
Effectively (from the code above), I have a form, from where the user
enters the vehicleID and set it as a session attribute.
Now, I want to call my UsedVehicleEJB's findByPrimaryKey() method with
the vehicleID as the parameter.
My Questions:
=
1. Should I call my EJB from the execute method and set the attributes
of the UsedVehicleEJB as session variables?
1.1 Can I make the entire EJB a session variable?
2. Should I be using the bean tag library in my view
"searchUsedCars.jsp" to call my EJB ?
What I think:
=
Given that the view should be independent of the model, I should not
call the EJB from "searchUsedCars.jsp" and hence, I should call the EJB
from the execute method.
Please comment.
TIA,
Kunal

RE: Newbie
Hi Gaurav ! Perhaps you should get started by reading "Read Me First - A path for newbies" available @ http://jakarta.apache.org/struts/resources/1st.html I would also recommend StrutsStudio from http://www.exadel.com to start with as a tool and look at the struts-config file it generates. StrutsStudio provides a good visual representation of the struts-config file. To understand the MVC architecture, I recommend reading the Struts API comments, which are greatly useful. These are available @ http://jakarta.apache.org/struts/api/index.html The classes that you should look at are "Action", "ActionForm", and "ActionServlet" to begin with.

Hi Andy ! If you follow the "Read Me First - A path for newbies", it'll get you on to JSPs, Servlets and the lot. It has some good links to "pre-requisites" also.

Hi all, I have a strong Perl/CGI background, but my JSP/Servlet/J2EE experience is related only to what I did in college. My job entails C development, but I really want to get more into this J2EE stuff. It's so much more enjoyable than this C work I am doing, but I can't seem to get my foot in the door. In looking for a J2EE development job, I keep hearing that I need more experience, which is perfectly understandable. But, I can't get experience without getting a job doing it first. My question is, how do I get my foot in the door so I can split my boring job and do what I really want to do? Do I need to go full tilt and get a certification or something like that? Any ideas would be most helpful. Even more helpful would be a J2EE job in the Chicago area where I could develop my professional career in this area. Thanks very much!

Application Module Configuration
Hi All! I am attempting to setup an application module named "my-module" as follows. However, whenever I send a request as http://127.0.0.1/my-app/my-module/action/index/ I get a 404 page returned. Now, when I send a request to the default module, i.e. http://127.0.0.1/my-app/action/index/ the appropriate jsp page is displayed. Also, when I just do http://127.0.0.1/my-app/my-module/action/, I still get a 404 error, whilst, from my understanding, I should get a 400 error. The following is the additional configuration I have added for my new application module. === web.xml === ... config /WEB-INF/struts-config.xml config/my-module /WEB-INF/struts-config-my-module.xml ... ... === web.xml === Is there anything else that I need to do ?
