create strut portlet in liferay

Create a Struts Portlet in Liferay

Step 1)Create a struts portlet

Step 2) put this jar file into the lib folder

commons-digester-1.8.jar

portals-bridges-common-1.0.jar

portals-bridges-struts-1.2.7-1.0.jar

Step 3) open liferay-plugin-package.properties file ,here you can add portal dependencies jar file

portal-dependency-jars=\

antlr2.jar,\

antlr3.jar,\

aopalliance.jar,\

asm-commons.jar,\

commons-beanutils.jar,\

commons-codec.jar,\

asm-util.jar,\

asm-xml.jar,\

asm.jar,\

struts-el.jar,\

struts.jar,\

commons-validator.jar

portal-dependency-tlds=\

liferay-portlet.tld,\

struts-bean-el.tld,\

struts-bean.tld,\

struts-html-el.tld,\

struts-html.tld,\

struts-logic-el.tld,\

struts-logic.tld,\

struts-tiles-el.tld,\

struts-tiles.tld,\

struts-nested.tld

Step 4)Edit the web.xml file

<servlet>

<servlet-name>PortletActionServlet</servlet-name>

<servlet-class>com.liferay.util.bridges.struts.LiferayPortletServlet</servlet-class>

<init-param>

<param-name>config</param-name>

<param-value>/WEB-INF/struts-config.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>PortletActionServlet</servlet-name>

<url-pattern>/portlet_action/*</url-pattern>

</servlet-mapping>

Step 5) Edit the Portlet.xml file

Change the <portlet-class> tag

<portlet-class>org.apache.portals.bridges.struts.StrutsPortlet</portlet-class>

<init-param>

<name>ServletContextProvider</name>

<value>com.liferay.util.bridges.struts.LiferayServletContextProviderWrapper</value>

</init-param>

<init-param>

<name>ViewPage</name>

<value>/portlet_action/struts-exercise/addname</value>

</init-param>

<init-param>

<name>EditPage</name>

<value>/portlet_action/struts-exercise/edit</value>

</init-param>

Step 6) Create StrutsSimple-config.xml

<?xml version="1.0"?>

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<struts-config>

<!-- Forms Beans -->

<form-beans>

<form-bean name="addNameForm" type="com.test.form.AddNameForm" />

</form-beans>

<!-- Action Mappings -->

<action-mappings>

<action path="/struts-exercise/view" forward="/html/strutsdemo/view.jsp" />

<action path="/struts-exercise/addname" type="com.test.action.AddNameAction" name="addNameForm" scope="request" validate="true" input="/html/strutsdemo/edit.jsp">

<forward name="/struts-exercise/addname/success" path="/html/strutsdemo/view.jsp" redirect="true" />

</action>

<action path="/struts-exercise/edit" forward="/html/strutsdemo/edit.jsp"/>

</action-mappings>

<!-- Custom Request Processor -->

<!-- <controller processorClass="org.apache.portals.bridges.struts.PortletTilesRequestProcessor" />

-->

<!-- Message Resources -->

<message-resources parameter="content.test.Language" />

</struts-config>

Step 7)create a portlet class called AddNameAction under src/com/test/action,

package com.test.action;

import com.test.form.AddNameForm;

import javax.portlet.ActionRequest;

import javax.portlet.ActionResponse;

import javax.portlet.PortletMode;

import javax.portlet.PortletPreferences;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

public class AddNameAction extends Action {

public ActionForward execute(

ActionMapping mapping, ActionForm form, HttpServletRequest req,

HttpServletResponse res)

throws Exception {

System.out.println("AddNameAction class!!!!!!!!!!!!!");

ActionRequest aReq = (ActionRequest) req.getAttribute("javax.portlet.request");

ActionResponse aRes = (ActionResponse) req.getAttribute("javax.portlet.response");

PortletPreferences prefs = aReq.getPreferences();

String userName = ((AddNameForm)form).getUserName();

prefs.setValue("name",userName);

prefs.store();

aRes.setPortletMode( PortletMode.VIEW );

return mapping.findForward("/struts-exercise/addname/success");

}

}

Step 8)create a portlet class called AddNameForm under src/com/test/form

package com.test.form;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionMessage;

public class AddNameForm extends ActionForm {

private static final long serialVersionUID = 1L;

private String userName;

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public void reset(ActionMapping mapping, HttpServletRequest req) {

userName = null;

}

public ActionErrors validate(

ActionMapping mapping, HttpServletRequest req) {

ActionErrors errors = new ActionErrors();

if ((userName == null) || (userName.length() < 1)) {

errors.add(

"userName", new ActionMessage("error.lastName.required"));

}

System.out.println("AddNameForm class!!!!!!!!!!!!!");

return errors;

}

public String toString() {

return userName;

}

}

Step 9)Create a view.jsp file under docroot/html/strutsdemo folder ,put this code into the view.jsp file

view.jsp

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>

<%@ taglib uri="http://portals.apache.org/bridges/struts/tags-portlet-html" prefix="html" %>

<%@ taglib uri="http://portals.apache.org/bridges/struts/tags-portlet-html" prefix="html" %>

<%@page import="javax.portlet.PortletPreferences"%>

<portlet:defineObjects />

<p>This is the Struts portlet.</p>

<%

PortletPreferences prefs = renderRequest.getPreferences();

String username = (String)prefs.getValue("name", "");

%>

<p>Hello <%=username%>!</p>

<html:link page="/portlet_action/struts-exercise/edit">Back to Edit Mode</html:link>

Step 10)create edit.jsp file under docroot/html/strutsdemo folder

edit.jsp

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>

<%@ taglib uri="http://portals.apache.org/bridges/struts/tags-portlet-html" prefix="html" %>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags-nested" prefix="nested" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<portlet:defineObjects />

<p>The Portlet is in Edit Mode.</p>

<html:form action="/struts-exercise/addname" method="post">

<table>

<tr>

<td>Name:</td>

<td><html:text name="addNameForm" property="userName"/></td>

</tr>

</table>

<html:submit>Add Name</html:submit>

</html:form>

<html:link page="/portlet_action/struts-exercise/view">Back to View Mode</html:link>

Step 11)deploy and run your portlet

It will look like this

Enter Name and click on Add Name

It will display view.jsp
