1:48 p.m.
I was finally able to piece together the relevant pieces of documentation to make a simple
Struts application work as a portlet in JBoss Portal 2.6.1. (JBoss AS 4.0.5)
Here are the relevant configuration files. You should be able to create the rest, as it is
just a simple HelloWorld type Struts app.
1.In web.xml, change Struts ActionServlet entry from:
org.apache.struts.action.ActionServlet
to:
org.apache.portals.bridges.struts.PortletServlet
2.Download the struts portal bridge jar from:
http://portals.apache.org/bridges/download.html
(Note that you must extract the jar from the downloaded archive file)
and place it in the /WEB-INF directory OR the server's /lib directory
3.Create the following descriptor files, and place them in the /WEB-INF directory of the
project:
portlet.xml:

| </render-context>
| <portlet-url-type default="action">
| <action path="/login.do"/>
| <action path="/testStrutsPortlet.do"/>
| </portlet-url-type>
| </config>
|
|
4.Unzip the struts portal bridge jar into a directory and extract the struts portal
specific .tld files from the tld directory. Put them in your WEB-INF directory (These
files are important because they will rewrite the URLs to access the portal)
Sample JSPs that import the TLDs:
login.jsp:
|
| <?xml version="1.0" encoding="UTF-8" ?>
| <%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles"
%>
| <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
| <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"
%>
| <%@ taglib uri="/WEB-INF/struts-portlet-html.tld" prefix="html"
%>
|
| <%@ page language="java" contentType="text/html;
charset=UTF-8"
| pageEncoding="UTF-8"%>
|
| <portlet:defineObjects/>
|
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
| <html xmlns="http://www.w3.org/1999/xhtml">
| <head>
| <meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />
| <title>Results</title>
| </head>
| <body>
|
| <html:form styleId="testForm" action="/testStrutsPortlet.do"
method="POST">
| <table>
| <tr><td><label>User:</label></td>
| <td><html:text property="user"
size="15"/></td>
| </tr>
| <tr><td><label>Password:</label></td>
| <td><html:password property="pwd"
size="15"/></td>
| </tr>
| <tr><td><html:submit
value="Search"/></td></tr>
| </table>
| </html:form>
|
|
| </body>
| </html>
|
|
results.jsp:
|
| <?xml version="1.0" encoding="UTF-8" ?>
| <%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles"
%>
| <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
| <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"
%>
| <%@ taglib uri="/WEB-INF/struts-portlet-html.tld" prefix="html"
%>
|
| <%@ page language="java" contentType="text/html;
charset=UTF-8"
| pageEncoding="UTF-8"%>
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
|
| <bean:define id="input_form" name="test_form"/>
|
| <html xmlns="http://www.w3.org/1999/xhtml">
| <head>
| <meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />
| <title>Response</title>
| </head>
| <body>
|
| <h3>Hello, <bean:write name="input_form"
property="user"/>. I am Brainiac.</h3>
|
| </body>
| </html>
|
|
In this example, login.jsp is set up to be the target forward of the first action called
in the app (it's the first JSP shown as a portlet). results.jsp is associated with the
forward that handles the response (/testStrutsPortlet.do). Note the the <init-param>
tags are the reason the login page is displayed.
This is just a bare bones example. The config files and .tlds are the keys to get it
working.
