Link view.jsp to processAction

[lucky singh, modificado hace 11 años.]

I am new to liferay. I have view.jsp,on form submit it should link to action class.
I have done following so far:
Have created “New Liferay Plug-in Project” with “Custom portlet class”and define portlet class as-CommentPortlet.
My view.jsp

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui" %>  
<%@ page import="javax.portlet.PortletPreferences" %>
<%@page import="javax.portlet.PortletURL"%>
<%@page import="javax.portlet.ActionRequest"%>

<portlet:defineobjects />
&lt;%
PortletPreferences prefs = renderRequest.getPreferences();
String greeting = (String)prefs.getValue(
    "greeting", "This is a discussion forum:");
%&gt;

&lt;%
PortletURL viewCommentURL = renderResponse.createActionURL();
viewCommentURL.setParameter(
ActionRequest.ACTION_NAME, "processAction");
%&gt;

	<portlet:renderurl var="viewCommentURL"> 
	<portlet:param name="jspPage" value="/html/commentportlet/view.jsp" /> 
	</portlet:renderurl>
<form name="<portlet:namespace/>fm" method="POST" action="<%=
	viewCommentURL.toString() %>">
	<fieldset>
	<legend>&lt;%= greeting %&gt;</legend>
		       Name:<input type="text" name="<portlet:namespace/>username"><br>
		Add comment:<input type="text" name="<portlet:namespace/>usercommenr">

			<br><input type="submit" value="Add" size="10" ">
		
	</fieldset>
</form>

My portlet.xml:

<portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" version="2.0">

		</security-role-ref>
		<security-role-ref>
			<role-name>user</role-name>
		</security-role-ref>
	</portlet>
</portlet-app>

My portlet class-with processAction

package com.test.comment;

import java.io.IOException;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletException;

//import com.liferay.portal.kernel.util.ParamUtil;
import com.liferay.util.bridges.mvc.MVCPortlet;

/**
 * Portlet implementation class CommentPortlet
 */
public class CommentPortlet extends MVCPortlet {
    public void processAction(
            ActionRequest actionRequest, ActionResponse actionResponse)
        throws IOException, PortletException {
    	
    	//String name = ParamUtil.getString(actionRequest, "username");
    	//String comment = ParamUtil.getString(actionRequest, "usercommenr");
    	//System.out.println("Your inputs ==> " + name + ", " + comment);
    	System.out.println("Inside Processaction...");
    }

}

I see "CommentPortlet is temporarily unavailable". Please suggest how to use processAction.

Hi,

if you're getting such error messages you should look at the console logs of your server to get more info why this error occurred.

use this form submit

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme"%>


<%@ page import="javax.portlet.*"%>
<%@ page import="com.liferay.portal.service.UserLocalServiceUtil" %>
<%@ page import="com.liferay.portal.model.Organization" %>
<%@ page import="com.liferay.portal.model.User" %>
<portlet:defineObjects />
<liferay-theme:defineObjects />

This is the <b>GroupCreationPortlet</b> portlet in View mode.

<form method="POST" action="<portlet:actionURL/>">
<input type="text" name="ownertarget"/>
<input type="submit" value="edit"/>
</form>

Hi Lucky,

Use <portlet:actionURL> instead of <portlet:renderURL>

renderURL will call render method while actionURL will call processAction() method of the portlet.
