AXIS 2 Sample web service with maven and eclipse
  1. Create meven project in eclipse

  1. Create Calculator Service Class

    • Create new package name as com.ruks.services
    • Create Caculator.java class inside the package.
    • Copy the below code to Caculator.java
        package com.ruks.serivces;

        public class Calculator {

            private static Calculator cal;
            private int X=1;
            private int Y=2;
            private int Result;

            private Calculator(){

            }

            public static Calculator getCal(){
                if(cal==null){
                    cal=new Calculator();
                }
                return cal;
            }

            public void setX(int x){
                this.X=x;
        //		System.out.println("set x: "+CalculatorService.X+" = "+x);
            }
            public void setY(int y){
                this.Y=y;
        //		System.out.println("set y: "+CalculatorService.Y+" = "+y);
            }
            public int getSum(){
                this.Result=this.X+this.Y;
        //		System.out.println("GET result: "+this.Result);
                return this.Result;
            }
        }

    
    • Create CaculatorService.java class inside the package.
    • Copy the code below to CaculatorService.java
        package com.ruks.serivces;

        public class CalculatorService {

            Calculator cal;

            public CalculatorService() {
                cal=Calculator.getCal();
            }

            public void setX(int x){
                cal.setX(x);
        //		System.out.println("set x: "+CalculatorService.X+" = "+x);
            }
            public void setY(int y){
                cal.setY(y);
        //		System.out.println("set y: "+CalculatorService.Y+" = "+y);
            }
            public int getSum(){
                return cal.getSum();
            }
        }


  
  1. Create service.xml file

    • Add a xml file to main/resources as service.xml
    • Add the this to the service.xml
        <?xml version="1.0" encoding="UTF-8"?>
        <service name="CalculatorService">

            <description>
                Simple Calculator Implemantain
            </description>

            <parameter name="ServiceClass">com.ruks.serivces.CalculatorService</parameter>

            <operation name="setX" mep="http://www.w3.org/ns/wsdl/in-out" namespace="http://serivces.ruks.com/xsd">
                <actionMapping>http://serivces.ruks.com/xsd/setX</actionMapping>;
                <messageReceiver class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />;
            </operation>;

            <operation name="setY" mep="http://www.w3.org/ns/wsdl/in-out" namespace="http://serivces.ruks.com/xsd">;
                <actionMapping>;http://serivces.ruks.com/xsd/setY</actionMapping>;
                <messageReceiver class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />;
            </operation>;

            <operation name="getSum" mep="http://www.w3.org/ns/wsdl/in-out" namespace="http://serivces.ruks.com/xsd">;
                <actionMapping>;http://serivces.ruks.com/xsd/getSum</actionMapping>;
                <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />;
            </operation>;

        </service>;
    
  1. Edit the pom.xml

    • add the axis2-java2wsdl-maven-plugin
        <plugin>
            <groupId>org.apache.axis2</groupId>
            <artifactId>axis2-java2wsdl-maven-plugin</artifactId>
            <configuration>
                <className>com.ruks.services.CalculatorService</className>
                <outputFileName>${project.build.directory}/CalculatorService.wsdl</outputFileName>
            </configuration>
            <executions>
                <execution>

                        <goal>java2wsdl</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    
    • add the axis2-aar-maven-plugin
        <plugin>
            <groupId>org.apache.axis2</groupId>
            <artifactId>axis2-aar-maven-plugin</artifactId>

                <wsdlFile>${project.build.directory}/CalculatorService.wsdl</wsdlFile>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>aar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
  
  1. Build the achive

  • Execute maven goal clean package to create aar achive
  • appropriate wsdl file and aar file will be created in the target directory
  1. Deploy the web service

  • Copy the Caculator.aar and paste to apache-tomcat/webapps/axis2/WEB-INF/services
  • Start the tomcat
  1. Verify the Service

    • Start the SoapUI
    • Navigate to http://localhost:8080/axis2/services/listServices
    • Make sure CalculatorService is listed
    • Click the CalculatorService and you get the WSDL URL
    • copy WSDL URL
    • Create new SoapUI soap Project
    • Add the URL to initial WSDL text box
    • Select the Soap Binding
    • Set the SetX request as below
        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.ruks.com">
           <soapenv:Header/>
           <soapenv:Body>
              <ser:setX>
                 <!--Optional:-->
                 <ser:x>10</ser:x>
              </ser:setX>
           </soapenv:Body>
        </soapenv:Envelope>
    
    • Set the SetY request as below
        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.ruks.com">
           <soapenv:Header/>
           <soapenv:Body>
              <ser:setY>
                 <!--Optional:-->
                 <ser:y>20</ser:y>
              </ser:setY>
           </soapenv:Body>
        </soapenv:Envelope>
    
    • Run the getSum request to see output
        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
           <soapenv:Body>
              <ns:getSumResponse xmlns:ns="http://services.ruks.com">
                 <ns:return>30</ns:return>
              </ns:getSumResponse>
           </soapenv:Body>
        </soapenv:Envelope>
