Portlet - Apache Pluto - Hello World Portlet

This is document just for documenting the steps for the helloworld sample which i did for learning pluto.

 

It takes two night for me succesfully deployed a helloworld in apache pluto portal server, i learned lots of thing in recently two night in learning using pluto even how the portlet should be configured in order to get it working in apache pluto.

 

so, below the steps for deploying a helloworld in apache pluto.

 

1. we should have successfully installed apache pluto open source portal server in our local.

 

2. create a helloword portleot application and its strcuture like below:

 

\---ch1_HelloWorld
    |   build-pluto.xml
    |   build.properties
    +---lib
    |       junit-4.7.jar
    |       portlet-api_2.0_spec-1.0.jar
    +---src
    |   \---chapter01
    |       \---code
    |           \---listing
    |                   HelloWorldPortlet.java
    \---WEB-INF
        |   portlet.xml
        |   web.xml
        \---jsp
        \---lib

 

 

 

3. let's start for each files mentioned in above structure

 

3.1 file chapter01.code.listing.HelloWorldPortlet

 

package chapter01.code.listing;

import java.io.IOException;
import java.io.PrintWriter;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

public class HelloWorldPortlet extends GenericPortlet {
	protected void doEdit(RenderRequest request, RenderResponse response)throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("You're now in Edit mode.");
	}

	protected void doHelp(RenderRequest request, RenderResponse response)throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("You're now in Help mode.");
	}

	protected void doView(RenderRequest request, RenderResponse response)throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("Hello world! You're in View mode.");
	}
}

</portlet-app>

 

 

3.4 file build.properties

 

pluto.portal.home=G:/Environment/Portal/pluto-2.0.3

 

 

3.5 file build-pluto.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<project name="HelloWorldPortlet" default="rebuild" basedir=".">

	</target>
	
	<target name="build.jar" depends="compile">

		<delete dir="${dir.classes}" failοnerrοr="false" />
		<delete dir="${dir.driver}" failοnerrοr="false"/>
	</target>
	
</project>

 

 

4. after we have those code in the portlet project, we can successfully generate one portlet war application file HelloWorldPortlet.war.

 

5. we have to copy the HelloWorldPortlet.war file into <pluto_home>\PlutoDomain directory.

 

6. next, we have to create a file 'hello.xml' for deploy this portlet application under <pluto_home>\conf\Catalina\localhost

 

 

hello.xml

 

 

<Context path="hello" docBase="../PlutoDomain/HelloWorldPortlet.war" crossContext="true"></Context>

 

 

7. then, we have to configure the HelloWorldPortlet in pluto-portal-driver-config.xml in order to get it shown on the pluto portlet page; 

 

     file <pluto-portal-driver-config.xml> path: <pluto_home>\webapps\pluto\WEB-INF\pluto-portal-driver-config.xm

   <render-config default="About Apache Pluto">
    <page name="About Apache Pluto" uri="/WEB-INF/themes/pluto-default-theme.jsp">
      <portlet context="/pluto" name="AboutPortlet"/>
      <portlet context="/testsuite" name="TestPortlet1"/>
      <portlet context="/hello" name="HelloWorldPortlet"/>
    </page>
    <page name="Test Page" uri="/WEB-INF/themes/pluto-default-theme.jsp">

      <portlet context="/testsuite" name="TestPortlet2"/>
      <portlet context="/hello" name="HelloWorldPortlet"/>
    </page>

      <portlet context="/hello" name="HelloWorldPortlet"/>
    </page>
  </render-config>
</pluto-portal-driver>

 

 

8. after we done all above steps, then, start the pluto portal server, the helloworld portlet application will looks like below:
