Post Subject : Tutorial on J2EE using JBOSS-4.x, Eclipse-3.x, Lomboz-3.x and
PostgreSQL-8.x on Windows XP
Ref. 1 : Tutorial for building J2EE Applications using JBOSS and ECLIPSE
http://www.tusc.com.au/tutorial/html/chap8.html (Chapter 8 : Web
Clients - Servlet & JSP)
Ref. 2 : Tutorial on J2EE using JBOSS, ECLIPSE and Lomboz (Forum on Ref. 1)
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=36910
Ref. 3 : Environment in use ;
- Windows XP SP2
- J2SDK 1.4.2_08
- Eclipse 3.0.2
- JBoss 4.0.2
- Lomboz 3.0.1 + emf-sdo-runtime-2.0.0
- PostgreSQL 8.0.3 (= DefaultDS)
Followings are some notes on Chapter 8 (Servlet & JSP) in Ref. 1
* The notes cover creations of a Servlet named AccessController and a JSP named
showItems.
* Task numbers are based on Ref. 1
* No change has been made to the server definition file
(jboss402postgres.server) thus far.
Task 1 : Create AccessController Servlet
- on completion of AccessController, "super.init(config);" is added in "init()"
method. No need to hide it.
public void init(ServletConfig config) throws ServletException {
| super.init(config);
| //TODO Method stub generated by Lomboz
| }
- in "web.xml", DTD is not shown at the top.
- it seems the file without dtd works normally. If any trouble, add DTD like
below and see;
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN"
| "http://java.sun.com/dtd/web-app_2_3.dtd";>
Task 2 : Add a business method to StoreAccess Bean named getAllItems()
: (as per the steps in Ref. 1)
Task 6 : Implement the processRequest method
Task 7 : Deploy the AccessController Servlet
- on completion of deployment, following message is shown in the console.
:
| 21:55:39,015 INFO [TomcatDeployer] deploy, ctxPath=/OnlineStore,
warUrl=file:/C:/jboss-4.0.2/server/postgres/tmp/deploy/tmp41196OnlineStore-exp.war/
Task 8 : Test the AccessController Servlet
(as per the steps in Ref. 1)
Task 9 : Create a JSP named showItems
: (as per the steps in Ref. 1)
Task 13 : Test the showItems.jsp page
=== Correction ===
- At the end of JBoss startup every time, an error message followed by others
on MBeans are shown as below.
- It seems there is no influence on the functions of beans up to this point,
i.e. end of Chapter 8.

- The messages can be eliminated with following corrections.
= remove ".bak" from "/jboss-4.0.2/server/postgres/deploy/jms.bak" to activate
the "jms" folder. (ref. Step 11 in the first post of this thread)
= put ".bak" to hajndi-jms-ds.xml under "/postgres/deploy/jms" to disable.
- "jms-ra.rar" is only one active file in "/postgres/deploy/jms" folder as a
result.
