<h1>Code Generator Tool Guide for Command Line and Ant Task</h1>
<p>The Code Generator tool consists of a command line version and an Ant
Task. This document will list the command line references and Ant task
references. Also in detail, this document shows how to build file using
custom Ant task and invoking the Code Generator from Ant.</p>
<p>This tool is bundled with the <a

<h2>Introduction</h2>
<p>This basic tool is implemented by the WSDL2Code class and just for the
convenience in the case of Java (which would be the majority) there is
another WSDL2Java class. One can choose to run the main classes directly or
use one of the scripts to run the WSDL2Code and WSDL2Java appropriately. (the
scripts are found in the bin directory of the <a href="../../download/1_1/download.html#std-bin">Standard Binary Distribution</a>)</p>
<a name="cmdline"></a>
<h2>Command Line Version</h2>
<p>For those users who wish to use the command line version of the tool, this
section will be of value.</p>

<h2>Ant Task</h2>
<p>The code generator also comes bundled with an Ant task. The ant task is
implemented by the org.apache.axis2.tool.ant.AntCodegenTask class. Following
are the ant task attributes.</p>

<h3>Example Build File Using the Custom Ant Task</h3>
<p>Following is an example ant build file that uses the custom Ant task. You
can use any wsdl file to test the example. Replace the "CombinedService.wsdl"
with the name of your wsdl file in the following script.</p>
<pre>1 &lt;?xml version="1.0"?&gt;
2 &lt;project name="CodegenExample" default="main" basedir="."&gt;
3
4 &lt;path id="example.classpath"&gt;
5 &lt;fileset dir="classes"&gt;
6 &lt;include name="**/*.jar" /&gt;
7 &lt;/fileset&gt;
8 &lt;/path&gt;
9
10 &lt;target name="declare" &gt;
11 &lt;taskdef name="codegen"
12 classname="org.apache.axis2.tool.ant.AntCodegenTask"
13 classpathref="example.classpath"/&gt;
15 &lt;/target&gt;
16
17 &lt;target name="main" depends="declare"&gt;
18 &lt;codegen
19 wsdlfilename="C:\test\wsdl\CombinedService.wsdl"
20 output="C:\output"
21 serverside="true"
22 generateservicexml="true"/&gt;
23 &lt;/target&gt;
24
25 &lt;/project&gt;</pre>
<p>In the above build script, from line 4 to 8 it sets the classpath and
includes all the .jar files (which are listed below) into the classpath. From
line 10 to 15 it creates a target to declare a task called "codegen" and sets
the appropriate class (org.apache.axis2.tool.ant.AntCodegenTask) within the
classpath in line 12. From line 17 to 23 it creates the "main" target to
generate the code from the given wsdl. There are some arguments set form line
19 to 22. Here in line 19 it sets the location of the wsdl. In line 20 it
sets the output directory in which the code is generated. Line 21 indicates
that this build generates the server side code(skeleton) and line 22
indicates that the services.xml is also generated.</p>
<p>Notice the main target that uses the "codegen" task which will use the
org.apache.axis2.tool.ant.AntCodegenTask class and run the code generation
tool internally while passing the relevant arguments and do the proper
generation. If a user types</p>
<p><code>&gt;ant</code> or <code>&gt;ant main</code></p>
<p>it will generate the server side code and services.xml for the given WSDL
file (C:\test\wsdl\CombinedService.wsdl -in the above instance) and the
generated code will be written to the specified output path (C:\output - in
the above instance).</p>
<p>For this Ant task to work the following jars need to be in the class
path.</p>
<ul>
<li>axis2-*.jar (from the Axis2 distribution)</li>
<li>wsdl4j-1.6.2.jar or higher (The WSDL4J implementation jar. Bundled with
the Axis2 distribution)</li>
<li>stax-api-1.0.1.jar (The StAX API's that contain the
javax.xml.namespace.QName class. This jar may be replaced by any other
jar that contains the javax.xml.namespace.QName implementation. However
Axis2 uses this class from the stax-api-1.0.1.jar which comes bundled
with the Axis2 distribution)</li>
<li>commons-logging-1.1.jar, neethi-2.0.jar and XmlSchema-1.2.jar (from the
Axis2 distribution)</li>
<li>axiom-api-1.2.1.jar and axiom-impl-1.2.1.jar (from the Axis2
distribution)</li>
<li>activation-1.1.jar (from the Axis2 distribution)</li>
<li>wstx-asl-3.1.0.jar (from the Axis2 distribution)</li>
</ul>

<h3>Invoking the Code Generator From Ant</h3>
<p>Since the users may find altering their ant class path a bit daunting they
can also follow an easier technique. The code generator main class can be
invoked directly through the build file.</p>
<p>Below is an example of a full build.xml needed to run WSDL2Java and
generate the Java source files, compile the sources, and build an AAR file
ready for deployment (These are done one by one, by calling the targets in
the build file separately):</p>

<p>Place the above file, named LoginEndpoint.wsdl, in the directory 'wsdl'
which is also inside the 'bin' directory. Run the wsdl2java command via the
ant task defined above (&gt;ant wsdl2java), and there will be a directory
called 'output' created. This directory contains the WSDL2Java generated
source.</p>
<p>An important detail is that an XMLBean class file is also generated by
WSDL2Java, TypeSystemHolder.class. That file is placed into build/classes by
the above ant task and will be needed to compile the generated sources. A
frequent problem is users get an error such as:</p>
<p><em><b>ClassNotFoundException : Cannot load SchemaTypeSystem. Unable to
load class with name
schemaorg_apache_xmlbeans.system.s68C41DB812F52C975439BA10FE4FEE54.TypeSystemHolder.
Make sure the generated binary files are on the classpath.</b></em></p>
<p>The TypeSystemHolder.class generated by WSDL2Java must be placed in your
classpath in order to avoid this error.</p>
<p>The next step is to modify the generated Skeleton Java Source file - the
Web service. This file as generated returns null and needs to be updated to
contain the business logic.</p>
<p>After the WSDL2Java command runs the file LoginEndpoint.wsdl, edit the
following file:</p>
<p>output/src/org/example/types/LoginServiceSkeleton.java. You should see the
following code:</p>
<pre class="code">/**
* LoginServiceSkeleton.java
*
* This file was auto-generated from WSDL
* by the Apache Axis2 version: 1.0-RC4 Apr 28, 2006 (05:23:23 IST)
*/
package org.example.types;
/**
* LoginServiceSkeleton java skeleton for the axisService
*/
public class LoginServiceSkeleton {
/**
* Auto generated method signature
* @param param0
*/
public login.types.ReturnWebLoginElementDocument webLogin
(login.types.WebLoginElementDocument param0 )
{
//Todo fill this with the necessary business logic
throw new java.lang.UnsupportedOperationException();
}
}</pre>
<p>Replace the contents of this file with the following, which uses the
complex types generated by WSDL2Java and the example wsdl file:</p>
<pre class="code">/**
* LoginServiceSkeleton.java
*
* This file was auto-generated from WSDL
* by the Apache Axis2 version: 1.0-RC4 Apr 28, 2006 (05:23:23 IST)
*/
package org.example.types;
import login.types.ReturnWebLoginElementDocument;
import login.types.ReturnWebLoginElementDocument.*;
import login.types.WebLoginElementDocument;
import login.types.WebLoginElementDocument.*;
/**
* Auto generated java skeleton for the service by the Axis code generator
*/
public class LoginServiceSkeleton {
/**
* Auto generated method signature
* @param webLoginElementDocument changed from param0
*/
public ReturnWebLoginElementDocument webLogin
(WebLoginElementDocument webLoginElementDocument ){
//Todo fill this with the necessary business logic
System.out.println("LoginServiceSkeleton.webLogin reached successfully!");
// Get parameters passed in
WebLoginElement webLoginElement = webLoginElementDocument.getWebLoginElement();
String userName = webLoginElement.getUserNameElement();
String password = webLoginElement.getUserPasswordElement();
System.out.println("LoginServiceSkeleton.webLogin userName: " + userName);
System.out.println("LoginServiceSkeleton.webLogin password: " + password);
// input paramaters would be used here
// prepare output
ReturnWebLoginElementDocument retDoc =
ReturnWebLoginElementDocument.Factory.newInstance();
ReturnWebLoginElement retElement = ReturnWebLoginElement.Factory.newInstance();
retElement.setWebUserNameElement("joe sixpack");
retElement.setSoapSessionIdElement("some_random_string");
System.out.println("validate retElement: " + retElement.validate());
retDoc.setReturnWebLoginElement(retElement);
System.out.println("validate retDoc: " + retDoc.validate());
System.out.println("LoginServiceSkeleton.webLogin returning...");

}

<p>The next steps assume the axis2.war has been deployed and has expanded in
a servlet container.</p>
<p>Run the 'jar_wsdl' ant task from the example build.xml (&gt;ant jar_wsdl),
which generates a jar file axis2_example_wsdl.jar in the 'bin/lib' directory.
This jar will be used to compile the client, and also will be placed in the
servlet container.</p>
<p>Next, run the 'aar' ant task from the example build.xml (&gt;ant aar),
which generates the deployable axis2 Web service. Place
dist/LoginEndpoint.aar into axis2/WEB-INF/services . Place
lib/axis2_example_wsdl.jar into axis2/WEB-INF/lib . Verify the happy axis
page loaded the services correctly - there should be the service
'LoginEndpoint' with the available operation 'webLogin' displayed.</p>
<p>The last step is to create and run the client. In the src directory create
the file org.client.LoginClient.java, with the contents below:</p>
<pre class="code">package org.client;
import org.apache.axis2.AxisFault;
import login.types.ReturnWebLoginElementDocument;
import login.types.ReturnWebLoginElementDocument.*;
import login.types.WebLoginElementDocument;
import login.types.WebLoginElementDocument.*;
import org.example.types.LoginServiceStub;
/**
* Login.
*
*/
public class LoginClient {
public static void main(String[] args) {
try {
System.out.println("webLogin, firing...");
LoginServiceStub stub = new LoginServiceStub();
WebLoginElementDocument webLoginElementDocument
= WebLoginElementDocument.Factory.newInstance();
WebLoginElement webLoginElement =
WebLoginElement.Factory.newInstance();
webLoginElement.setUserNameElement("joe");
webLoginElement.setUserPasswordElement("sixpack");
webLoginElementDocument.setWebLoginElement(webLoginElement);
System.out.println("validate: " + webLoginElement.validate());
stub.webLogin(webLoginElementDocument);
ReturnWebLoginElementDocument returnWebLoginElementDocument =
stub.webLogin(webLoginElementDocument);
System.out.println("Client returned");
ReturnWebLoginElementDocument.ReturnWebLoginElement
retElement = returnWebLoginElementDocument.getReturnWebLoginElement();
System.out.println("WebUserName: " + retElement.getWebUserNameElement());
System.out.println("SOAPSessionId: " + retElement.getSoapSessionIdElement());
System.out.println("webLogin, completed!!!");
} catch (AxisFault axisFault) {
axisFault.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}</pre>
<p>Now run the ant task 'runLogin' (&gt;ant runLogin). The following output
should appear:</p>
<pre class="code">runLogin:
[echo] running the webLogin client
[java] webLogin, firing...
[java] validate: true
[java] Client returned
[java] WebUserName: joe sixpack
[java] SOAPSessionId: some_random_string
[java] webLogin, completed!!!</pre>
