Expose Soap Web Service From Liferay Custom Portlet Plugin

Exposing soap web service for a custom plugin

STEPS:

Step 1: Create one portlet plugin project, name: SoapExposer, after appending suffix of portlet plugin project full name of project will be SoapExposer-portlet.
Create one portlet name: Exposer, inside created project.

Step 2:Create service.xml,define entity  as shown in below screen.

In service defintion don't forget to make remote-service="true",

Once we  make remote-service="true" in service.xml and after building service we will get EmployeeManageServiceImpl.java

Now build service.

Step 3: Paste below code in view.jsp

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

<%@page import="javax.portlet.PortletURL"%>

<portlet:defineObjects />

<p style="border:1px solid green;">ADD Employee Details</p>

<%

PortletURL addEmployeeDetailURL = renderResponse.createActionURL();

addEmployeeDetailURL.setParameter(actionRequest.ACTION_NAME,"addEmployeeDetail");

%>

 <form action="<%=addEmployeeDetailURL.toString()%>"  method="POST">

<b>Employee First Name</b><br/>

<input  type="text" name="<portlet:namespace/>employeeFirstName" /><br/>

<b>Employee Last Name</b><br/>

<input  type="text" name="<portlet:namespace/>employeeLastName" /><br/>

<b>Employee Age</b><br/>

<input  type="text" name="<portlet:namespace/>employeeAge" /><br/>

<b>Employee Number</b><br/>

<input  type="text" name="<portlet:namespace/>employeeNumber" /><br/>

<br/>

<input type="submit" value="AddEmployeeDetails"/>

</form>

Step 4: Paste below code in portlet controller: Exposer.java

package com.test;

import java.io.IOException;

import javax.portlet.ActionRequest;

import javax.portlet.ActionResponse;

import javax.portlet.PortletException;

import com.liferay.counter.service.CounterLocalServiceUtil;

import com.liferay.portal.kernel.exception.SystemException;

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

import com.liferay.util.bridges.mvc.MVCPortlet;

import com.slayer.model.EmployeeManage;

import com.slayer.model.impl.EmployeeManageImpl;

import com.slayer.service.EmployeeManageLocalServiceUtil;

/**

 * Portlet implementation class Exposer

 */

public class Exposer extends MVCPortlet {

//Adding employee details

public void addEmployeeDetail(ActionRequest actionRequest,

ActionResponse actionResponse) throws IOException, PortletException {

       

System.out.println("inside addEmployeeDetail method...");

String employeeFirstName = ParamUtil.getString(actionRequest, "employeeFirstName");

String employeeLastName = ParamUtil.getString(actionRequest, "employeeLastName");

int employeeAge = ParamUtil.getInteger(actionRequest, "employeeAge");

String employeeNumber = ParamUtil.getString(actionRequest, "employeeNumber");

//Instanciate an empty object of type EmployeeManageImpl

EmployeeManage employeeManage = new EmployeeManageImpl();

//Generate a unique primary key to be set

long employeeId = 01;

try {

employeeId = CounterLocalServiceUtil.increment();

} catch (SystemException e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

//set the field for this object

employeeManage.setEmployeeId(employeeId);

employeeManage.setEmpFirstName(employeeFirstName);

employeeManage.setEmpLastName(employeeLastName);

employeeManage.setEmpAge(employeeAge);

employeeManage.setEmpNumber(employeeNumber);

//called service layer API to save the object

try {

EmployeeManageLocalServiceUtil.addEmployeeManage(employeeManage);

System.out.println("New employee detail added successfully...");

actionResponse.setRenderParameter("jspPage", "/html/exposer/view.jsp");

} catch (SystemException e) {

System.out.println("something happened wrong while adding new employee detail");

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

Step 5: Paste below java code in EmployeeManageServiceImpl.java and then build service once again.

public List<EmployeeManage>  getlistOfEmployee()

{

List<EmployeeManage> employeeList = null;

try {

employeeList = employeeManageLocalService.getEmployeeManages(-1, -1);

} catch (SystemException e) {

return employeeList; 

}

public EmployeeManage getEmployeeDetailBasedOnEmpId(long employeeId){

EmployeeManage employeeDetails = null;

} catch (PortalException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SystemException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return employeeDetails;

}

}

Step 6: Now by using build wsdd we will expose this service to outside world. By doing this a new file 'server-config.wsdd' will get generate inside WEB-INF. This is the web service deployment descriptor that contains information about the web services that we are exposing.

Follow below screen.

Step 7: Now deploy portlet and add on portal page for adding employee data.
As shown in below screen.

Step 8: hit below url on browser, follow below screen                                                                                                           http://localhost:8080/SoapExposer-portlet/api/axis

Below is the soap wsdl generated file.
