Hi Hazma,
Here is a small demo portlet which takes events from the JSF customer portlet. To do this, you need to create a
NonFacesPortlet in the bookings portlet demo with this code:
package com.liferay.faces.demos.portlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Serializable;
import javax.portlet.EventRequest;
import javax.portlet.EventResponse;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.ProcessEvent;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import com.liferay.faces.bridge.event.EventPayloadWrapper;
import com.liferay.faces.demos.dto.Customer;
public class NonFacesPortlet extends GenericPortlet {
public NonFacesPortlet() {
System.err.println("!@#$ nfs created.");
}
@Override
@ProcessEvent(qname="{http://liferay.com/events}ipc.customerSelected")
public void processEvent(EventRequest eventRequest, EventResponse eventResponse)
throws PortletException, IOException {
Serializable value = eventRequest.getEvent().getValue();
// FACES-1465: If the payload is wrapped, then a redirect may have taken place. In any case, get the
// payload from the wrapper.
if (value instanceof EventPayloadWrapper) {
value = ((EventPayloadWrapper) value).getWrapped();
}
Customer customer = (Customer) value;
System.err.println("!@#$ customer.getName() = " + customer.getFirstName() + " " + customer.getLastName());
System.err.println(Long.toString(customer.getCustomerId()));
eventRequest.getPortletSession().setAttribute("customerId", Long.toString(customer.getCustomerId()));
}
@Override
protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
String customerId = (String) request.getPortletSession().getAttribute("customerId");
PrintWriter writer = response.getWriter();
writer.write("customerId = " + customerId);
}
}
Then add this to the bookings
portlet.xml file:
<portlet>
<portlet-name>nfp</portlet-name>
<display-name>NonFacesPortlet</display-name>
<portlet-class>com.liferay.faces.demos.portlet.NonFacesPortlet</portlet-class>
<supports>
<mime-type>text/html</mime-type>
<portlet-mode>view</portlet-mode>
</supports>
<portlet-info>
<title>nfp</title>
<short-title>nfp</short-title>
<keywords>nfp</keywords>
</portlet-info>
<supported-processing-event>
<qname xmlns:x="http://liferay.com/events">x:ipc.customerSelected</qname>
</supported-processing-event>
</portlet>
Then add this to the bookings
liferay-portlet.xml file:
<portlet>
<portlet-name>nfp</portlet-name>
<ajaxable>false</ajaxable>
</portlet>
Add
<portlet id="nfp" /> to
liferay-display.xml under the
category tag.
To allow the portal to pass events between pages, you need to add these lines to your
portal-ext.properties:
portlet.event.distribution=layout-set
layout.default.p_l_reset=false
tags.compiler.enabled=false
Then start up your server, and add the nfp portlet to a new page. Add the customers portlet to a different page and check the
Send Redirect (Liferay Only) box and select the page which nfp is on from the dropdown. Now click on a customer and you should be sent to a new page which will tell you the ID of the customer that you clicked on.
Let me know if you need any more info.
