Service Builder in Plugin SDK

Service Builder in PluginSDK (Lifera 5.2)

1. Create a portlet > create calculatedeductible “Calculate Deductible”
2. Create portlet-ext.xml and place it in root folder of liferay ie Liferay-Portal folder which contains workspace and tomcat etc.

##MySql

jdbc.default.driverClassName=com.mysql.jdbc.Driver

jdbc.default.url=jdbc:mysql://localhost/lportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

jdbc.default.username=lportal

jdbc.default.password=lportal

3. Create service.xml in WEB-INF folder as below.

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 5.2.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_5_2_0.dtd">

<service-builder package-path="com.plugin.Deductible">

<author>Harshal Shah</author>

<namespace>calculate</namespace>

<entity name="Deductible" local-service="true" remote-service="false">

<column name="productId" type="long" primary="true" />

<column name="make" type="String" primary="true"/>

<column name="model" type="String" primary="true" />

<column name="deductible" type="long" />

<order by="asc">

<order-column name="make" />

</order>

</entity>

</service-builder>

4. Now double click on build.xml>build services target of that portlet…by now you know what I mean .
5. Modify portlet.xml to

<?xml version="1.0"?>

<portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" version="2.0" 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">

</portlet-app>

Here we have modified portlet-class since we want to include the edit and view modes also added <portlet-mode>

6. Create a class Calculate Portlet which implements different modes. Create this package under the source folder under WEB-INF.

package com.plugin.Deductible.controller;

import com.plugin.Deductible.action.CalculateLocalServiceUtil;

import java.io.IOException;

import javax.portlet.ActionRequest;

import javax.portlet.ActionResponse;

import javax.portlet.GenericPortlet;

import javax.portlet.PortletException;

import javax.portlet.PortletMode;

import javax.portlet.PortletPreferences;

import javax.portlet.PortletRequestDispatcher;

import javax.portlet.PortletURL;

import javax.portlet.RenderRequest;

import javax.portlet.RenderResponse;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

public class CalculatePortlet extends GenericPortlet {

public void init() throws PortletException {

editJSP = getInitParameter("edit-jsp");

viewJSP = getInitParameter("view-jsp");

}

public void doEdit(RenderRequest renderRequest,

RenderResponse renderResponse) throws IOException, PortletException {

renderResponse.setContentType("text/html");

PortletURL addName = renderResponse.createActionURL();

addName.setParameter("addName", "addName");

renderRequest.setAttribute("addNameUrl", addName.toString());

include(editJSP, renderRequest, renderResponse);

}

public void doView(RenderRequest renderRequest,

RenderResponse renderResponse) throws IOException, PortletException {

include(viewJSP, renderRequest, renderResponse);

}

public void processAction(ActionRequest actionRequest,

ActionResponse actionResponse) throws IOException, PortletException {

String addName = actionRequest.getParameter("addName");

if (addName != null) {

try {

String make = actionRequest.getParameter("Make");

String model = actionRequest.getParameter("Model");

String deductible = actionRequest.getParameter("Deductible");

long ded=0;

if (make!=null && model!=null && deductible != null ) {

System.out.println(deductible);

Thread.sleep(5000);

try{

ded = Long.parseLong(deductible);}

catch(NumberFormatException e){

System.out.println("deductible is not a number");

actionResponse.setPortletMode(PortletMode.VIEW);

}

CalculateLocalServiceUtil.addProduct(make, model, ded);

}

Thread.sleep(5000);

} catch (Exception e) {

e.printStackTrace();

}

actionResponse.setPortletMode(PortletMode.VIEW);

}

}

protected void include(String path, RenderRequest renderRequest,

RenderResponse renderResponse) throws IOException, PortletException {

PortletRequestDispatcher portletRequestDispatcher = getPortletContext()

.getRequestDispatcher(path);

if (portletRequestDispatcher == null) {

_log.error(path + " is not a valid include");

} else {

portletRequestDispatcher.include(renderRequest, renderResponse);

}

}

protected String editJSP;

protected String viewJSP;

private static Log _log = LogFactory.getLog(CalculatePortlet.class);

}

7. Now different modes are set we will implement the wrapper for the service builder classess.

Create CalculateLocalService Util under WEB-INF action folder

package com.plugin.Deductible.action;

import com.plugin.Deductible.service.DeductibleLocalServiceUtil;

import java.util.List;

import com.plugin.Deductible.service.persistence.DeductiblePK;

import com.plugin.Deductible.service.impl.DeductibleLocalServiceImpl;

import com.plugin.Deductible.model.Deductible;

import com.plugin.Deductible.service.persistence.DeductiblePersistence;

import java.util.List;

import com.plugin.Deductible.service.base.DeductibleLocalServiceBaseImpl;

import java.util.Date;

import java.util.List;

import javax.portlet.ActionRequest;

import javax.transaction.Transaction;

import com.liferay.counter.service.CounterLocalServiceUtil;

import com.liferay.portal.PortalException;

import com.liferay.portal.SystemException;

import com.liferay.portal.kernel.util.WebKeys;

import com.liferay.portal.model.User;

import com.liferay.portal.service.UserLocalServiceUtil;

import com.liferay.portal.theme.ThemeDisplay;

public class CalculateLocalServiceUtil {

public static Deductible addProduct(String make,String model,long deductible) throws SystemException,

PortalException {

DeductiblePK dPk = new DeductiblePK();

try {

long productId = CounterLocalServiceUtil.increment(Deductible.class

.getName());

dPk.setProductId(productId);

dPk.setMake(make);

dPk.setModel(model);

Deductible product = DeductibleLocalServiceUtil

.createDeductible(dPk);

DeductibleLocalServiceUtil.updateDeductible(product, false);

return product;

} catch (Exception e) {

System.out.println("Junk piece of crap..Caught you");

}

return null;

}

public static List<Deductible> getAllProducts() throws SystemException,

PortalException {

try {

int end = DeductibleLocalServiceUtil.getDeductiblesCount();

return DeductibleLocalServiceUtil.getDeductibles(0,end);

} catch (Exception e) {

System.out.println("Junk piece of crap..Caught you");

}

return null;

}

}

8. Now create the jsp’s under docroot.

View.jsp;

<%@ include file="init.jsp" %>

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

<portlet:defineObjects />

<%

List products =(List)CalculateLocalServiceUtil.getAllProducts();

Deductible product =null;%>

<table style="border: lpx solid #CCC; width; 100%;padding:5px;">

<tr>

<td style="color: #12558E;">Make</td>

<td style="color: #12558E;"> Model</td>

<td style="color: #12558E;"> Deductible</td>

</tr>

<%System.out.println("In view.jsp"); %>

<c:if test="<%=products!=null %>">

<% for (int i=0; i<products.size(); i++ ){

product=(Deductible)products.get(i);

%>

<tr>

<td><%=product.getMake() %></td>

<td> <%=product.getModel() %></td>

<td> <%=product.getDeductible() %></td>

</tr>

<%}%>

</c:if>

</table>

Edit.jsp:

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

<jsp:useBean class="java.lang.String" id="addNameUrl" scope="request" />

<portlet:defineObjects />

<form

id = "<portlet:namespace />addForm"

action="<%=addNameUrl %>"

method="post">

<table>

<tr>

<td>Make:</td>

<td><input type="text" name="Make"></td>

<td>Model:</td>

<td> <input type="text" name="Model"></td>

<td>Deductible:</td>

<td> <input type="text" name="Deductible"></td>

</tr>

</table>

<input type="submit" id="nameButton" title="Add Name" value="Add Name">

</form>

Init.jsp:

<%@ page import="java.io.Serializable" %>

<%@ page import="java.io.StringReader" %>

9. Compile, deploy from ant target and start the tomcat.
