Create site programmatically in Liferay

Create site programmatically in Liferay

This code does creates a site and adds site template to it...

1. It will reaad site name from portal-ext.properties file
2. It will get the site template already created from browser and then add this template to our newly created site.
3. It will get logo from the class path -WEB-INF/mylogo.png
4. It will place logo to our site..

Adding tags programatically after blog entry added in Blogs portlet

Adding tags programatically after blog entry added in Blogs portlet

1. create a hook and add portal properties.

2. In portal properties write the portall property as given below:

value.object.listener.com.liferay.portlet.blogs.model.BlogsEntry=com.test.liferay.portlet.blogs.NewBlogEntryListener

    we are doing for  blog content , so we need to create listener for BlogsEntry model.

3. create the above class -NewBlogEntryListener in the package as mentioned above:

4. Write the code below:

NewBlogEntryListener.java

-------------------------------------- (The below code is for creating tags  and also for sending mail when a blog entry created)

package com.test.liferay.portlet.blogs;

Interportlet Communication using Public Render Parameters

Interportlet Communication using Public Render Parameters

Create two portlets named as PortletA and PortletB with classes PortletActionA, PortletActionB.

IN PortletA , do below things:
-----------------------------------
portlet.xml --> IN portlet configuration mention the below line :
<supported-public-render-parameter>firstName</supported-public-render-parameter>

after ending the portlet tag give the below lines:
 <public-render-parameter>
        <identifier>firstName</identifier>
          <qname xmlns:x="http://sun.com/params">x:firstName</qname>
    </public-render-parameter>
  

Repeat the above thing in PortletB also...


In Portlet A:-

PortletActionA Class:-

set the render parameter as below like:
public void portletAActionURL(ActionRequest actionRequest, ActionResponse actionResponse){

System.out.println("portletA callign");

actionResponse.setRenderParameter("firstName", "devi");
}


In PortletB :-


doview() method write below code:

String firstname =renderRequest.getParameter("firstName");

System.out.println("firstname == "+firstname);
renderRequest.setAttribute("firstname", firstname);



Then u will observe the value in your jsp as

renderRequest.getAttribute("firstName") and print this..

Global class loader and Portal class loader

What is meant by Global Class Loader, Portal Class Loader?

Global class Loader : is tomcat/lib and tomcat/lib/ext folders jar files.
Portal class Loader : tomcat/webapps/root/web-inf/lib folder  jar files
(ex: D:\workspace\liferay-developer-studio\liferay-portal-6.2-ee-sp3\tomcat-7.0.42\webapps\ROOT\WEB-INF\lib)

Global class loader jars are available to all the portlet. Make sure when adding any jars in your portal class lader check whether it is exist in global class loader or not. Viceversa for Global class loader.
In this way you can avoid ClassCastException .

In Hook portlet --> If you override portal jsp , you can get portal and global class loaders. But you can't get jars loaded in this HOOK..
