<h1>Code Listing For Axis2SampleDocLitService Service</h1>

<h2>Server:</h2>

<h3>echoString</h3>

<p>Locate the following code segment in "Axis2SampleDocLitServiceSkeleton.java".<br>
</p>
<source><pre>public org.apache.axis2.userguide.xsd.EchoStringReturnDocument 
        echoString(org.apache.axis2.userguide.xsd.EchoStringParamDocument param4 ){
        //Todo: fill this with the necessary business logic
        throw new  java.lang.UnsupportedOperationException();
   }
</pre></source>

<p>Then complete the code by adding the business logic as shown below:</p>
<source>
<pre>public org.apache.axis2.userguide.xsd.EchoStringReturnDocument 
       echoString(org.apache.axis2.userguide.xsd.EchoStringParamDocument param4) throws Exception {
       //Use the factory to create the output document
       org.apache.axis2.userguide.xsd.EchoStringReturnDocument retDoc = 
           org.apache.axis2.userguide.xsd.EchoStringReturnDocument.Factory.newInstance();
      //send the string back.
      retDoc.setEchoStringReturn(param4.getEchoStringParam());
      return retDoc;
  }</pre>
</source>

<h3>echoStringArray</h3>

<p>The code segment for echoStringArray is shown below:</p>
<source>
<pre>public org.apache.axis2.userguide.xsd.EchoStringArrayReturnDocument 
      echoStringArray(org.apache.axis2.userguide.xsd.EchoStringArrayParamDocument param0) throws Exception {
      //Use the factory to create the output document.
     org.apache.axis2.userguide.xsd.EchoStringArrayReturnDocument retDoc = 
     org.apache.axis2.userguide.xsd.EchoStringArrayReturnDocument.Factory.newInstance();
     //Get the String array from the input parameters.
     String[] inParams = param0.getEchoStringArrayParam().getStringArray();
     org.apache.axis2.userguide.xsd.ArrayOfstringLiteral retParams =
            org.apache.axis2.userguide.xsd.ArrayOfstringLiteral.Factory.newInstance();
     //Set the input parameters to the output parameters for echoing.
     for (int i = 0; i &lt; inParams.length; i++) {
         retParams.addString(inParams[i]);<br>     }
     //return the output document.
    retDoc.setEchoStringArrayReturn(retParams);
    return retDoc;
   }</pre>
</source>

<h3>echoStruct</h3>

<p>The code segment for echoStruct is shown below:</p>
<source><pre>
  public org.apache.axis2.userguide.xsd.EchoStructReturnDocument 
        echoStruct(org.apache.axis2.userguide.xsd.EchoStructParamDocument param2) throws Exception {
        //Use the factory to create the output document.
        org.apache.axis2.userguide.xsd.EchoStructReturnDocument retDoc =
        org.apache.axis2.userguide.xsd.EchoStructReturnDocument.Factory.newInstance();
        //Get the SOAPStrcut from the incoming parameters
        org.apache.axis2.userguide.xsd.SOAPStruct inStruct = param2.getEchoStructParam();
        //Struct for the sending back
        org.apache.axis2.userguide.xsd.SOAPStruct outStruct =
                org.apache.axis2.userguide.xsd.SOAPStruct.Factory.newInstance();
        //Fill the outgoing struct
        outStruct.setVarFloat(inStruct.getVarFloat());
        outStruct.setVarInt(inStruct.getVarInt());
        outStruct.setVarString(inStruct.getVarString());
        //Set the outgoing document.
        retDoc.setEchoStructReturn(outStruct);
        return retDoc;
    }
</pre></source>

<h2>Client:</h2>

<h3>Client for echoString Operation</h3>

<p>The following code fragment shows the necessary code for utilizing the
echoString operation of the Axis2SampleDocLitService that we have already
deployed. The code is very simple to understand and the explanations are in
the form of comments.</p>
<source><pre>     try {
                      org.apache.axis2.userguide.Axis2SampleDocLitServiceStub stub 
                        = new org.apache.axis2.userguide.Axis2SampleDocLitServiceStub(null,
                           "http://localhost:8080/axis2/services/Axis2SampleDocLitService");
                      //Create the request document to be sent.
                      org.apache.axis2.userguide.xsd.EchoStringParamDocument reqDoc =
                          org.apache.axis2.userguide.xsd.EchoStringParamDocument.Factory.newInstance();
                      reqDoc.setEchoStringParam("Axis2 Echo");
                      //invokes the Web service.
                      org.apache.axis2.userguide.xsd.EchoStringReturnDocument resDoc = 
                                        stub.echoString(reqDoc);
                      System.out.println(resDoc.getEchoStringReturn());
                      } catch (java.rmi.RemoteException e) {
                       e.printStackTrace();
                      }
</pre></source>

<p>Similarly the following code fragments show client side code for
echoStringArray operation and echoStruct operation respectively.</p>
