<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> | |

<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 <?xml version="1.0"?> | |
2 <project name="CodegenExample" default="main" basedir="."> | |
3 | |
4 <path id="example.classpath"> | |
5 <fileset dir="classes"> | |
6 <include name="**/*.jar" /> | |
7 </fileset> | |
8 </path> | |
9 | |
10 <target name="declare" > | |
11 <taskdef name="codegen" | |
12 classname="org.apache.axis2.tool.ant.AntCodegenTask" | |
13 classpathref="example.classpath"/> | |
15 </target> | |
16 | |
17 <target name="main" depends="declare"> | |
18 <codegen | |
19 wsdlfilename="C:\test\wsdl\CombinedService.wsdl" | |
20 output="C:\output" | |
21 serverside="true" | |
22 generateservicexml="true"/> | |
23 </target> | |
24 | |
25 </project></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>>ant</code> or <code>>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 (>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>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 | |

import login.types.WebLoginElementDocument; | |
import login.types.WebLoginElementDocument.*; | |

public class LoginServiceSkeleton { | |

ReturnWebLoginElement retElement = ReturnWebLoginElement.Factory.newInstance(); | |
retElement.setWebUserNameElement("joe sixpack"); | |
retElement.setSoapSessionIdElement("some_random_string"); | |
System.out.println("validate retElement: " + retElement.validate()); | |

<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 (>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 (>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' (>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> | |
