How to develop an IPC(inter Portlet Comunication) with PRP (Public Render Parameter)
How to develop an IPC (Inter Portlet Communication) with PRP (Public Render Parameter)
- 1. Generate Maven Project.
First one generate maven proyect with following archetype:
mvn archetype:generate
-DarchetypeGroupId=org.jboss.portletbridge.archetypes
-DarchetypeArtifactId=1.2-basic
-DarchetypeVersion=2.0.0.CR1
-DgroupId=com.intralot.portlet
-DartifactId=PltPruebaPRP
-DarchetypeRepository=http://repository.jboss.org/maven2/
- 2. Changes to realizing in the created template
After creating my template I did the following thing:
- In the pom.xml file
... <build> <defaultGoal>package</defaultGoal> <finalName>PltPruebaPRP</finalName> <sourceDirectory>src/main/java</sourceDirectory> .... </build> ... <deployer> <type>installed</type> <deployables> <deployable> <location>target/PltPruebaPRP.war</location> <pingURL>http://localhost:8080/simple-portal/</pingURL> </deployable> </deployables> </deployer>

- 3. Project’s Structure
- File MyPRPBean.java
public class MyPRPBean {
int id;
//getters y setters
}
- File MyEventHandler.java
public class MyEventHandler
implements BridgeEventHandler {
public EventNavigationResult handleEvent(FacesContext context, Event event) {
System.out.println("Evento: "+event.getName());
return null;
}
}
- File MyPRPHandler.java
public class MyPRPHandler implements BridgePublicRenderParameterHandler{
public void processUpdates(FacesContext context){
ELContext elContext = context.getELContext();
MyPRPBean bean =
(MyPRPBean) elContext.getELResolver().getValue(elContext, null, "myPRPBean");
if(null != bean){
System.out.println("processUpdates from PRPHandler: " + bean.getId());
} else {
System.out.println("evento nulo** ");
}
}
}
- File MyBean.java
public class MyBean {
private String cadena="";
//getters y setters
public String accion() {
try {
Object response = FacesContext.getCurrentInstance().getExternalContext().getRequest();
if (response instanceof StateAwareResponse) {
StateAwareResponse stateResponse = (StateAwareResponse) response;
stateResponse.setRenderParameter("id",cadena);
}
} catch (Exception e) {
}
return "actualizar";
}
}
- File /portlet1/home.xhtml
- /portlet2/home.xhtml
<h1>Hola portlet 2</h1>
<p>Parametro ingresado: #{myPRPBean.id}</p>
- Generated the Project with Maven: # mvn package
- Then the deployment, portlets don’t produce nothing, I mean that don’t produce an event in any place neither interface or console
- My question is: ¿What part of code is wrong? ¿Is posible have both portlets in .war file for separate?
