Creating Java proxy classes using Apache Axis

You can use the Apache Axis WSDL2Java tool to convert a LiveCycle service into Java proxy classes. These classes enable you to invoke LiveCycle service operations. Using Apache Ant, you can generate Axis library files from a service WSDL. You can download Apache Axis at the URL http://ws.apache.org/axis/ .

You can generate Axis Java library files by performing the following steps:

1. Install Apache Ant on the client computer. It is available at http://ant.apache.org/bindownload.cgi .

   • Add the bin directory to your class path.

   • Set the ANT_HOME environment variable to the directory where you installed Ant.

2. Install Apache Axis 1.4 on the client computer. It is available at http://ws.apache.org/axis/ .

3. Set up the class path to use the Axis JAR files in your web service client, as described in the Axis installation instructions at http://ws.apache.org/axis/java/install.html .

4. Use the Apache WSDL2Java tool in Axis to generate Java proxy classes. Create an Ant build script to accomplish this task. The following script is a sample Ant build script named build.xml:

   <?xml version="1.0"?> 
   <project name="axis-wsdl2java"> 
    
   <path id="axis.classpath"> 
   <fileset dir="C:\axis-1_4\lib" > 
       <include name="**/*.jar" /> 
   </fileset> 
   </path> 
    
   <taskdef resource="axis-tasks.properties" classpathref="axis.classpath" /> 
    
   <target name="encryption-wsdl2java-client" description="task"> 
   <axis-wsdl2java 
       output="C:\JavaFiles" 
       testcase="false" 
       serverside="false" 
       verbose="true" 
       username="administrator" 
       password="password" 
       url="http://localhost:8080/soap/services/EncryptionService?wsdl&amp;lc_version=9.0.1" > 
   </axis-wsdl2java> 
   </target> 
    
   </project>

   Within this Ant build script, notice that the url property is set to reference the Encryption service WSDL running on localhost. The username and password properties must be set to a valid AEM forms user name and password.

5. Create a BAT file to execute the Ant build script. The following command can be located within a BAT file that is responsible for executing the Ant build script:

   ant -buildfile "build.xml" encryption-wsdl2java-client

   The JAVA files are written to the C:\JavaFiles folder as specified by the output property. To successfully invoke the LiveCycle service, import these JAVA files into your class path.

   By default, these files belong to a Java package named com.adobe.idp.services . It is recommended that you place these JAVA files into a JAR file. Then import the JAR file into your client application’s class path.

   Note: There are different ways to put .JAVA files into a JAR. One way is using a Java IDE like Eclipse. Create a Java project and create a com.adobe.idp.services package (all .JAVA files belong to this package). Next import all the .JAVA files into the package. Finally, export the project as a JAR file.

6. Amend the URL in the EncryptionServiceLocator class to specify the encoding type. For example, to use base64, specify ?blob=base64 to ensure that the BLOB object returns binary data. That is, in the EncryptionServiceLocator class, locate the following line of code:

   http://localhost:8080/soap/services/EncryptionService;

   and change it to:

   http://localhost:8080/soap/services/EncryptionService?blob=base64;

7. Add the following Axis JAR files to your Java project’s class path:

   • activation.jar

   • axis.jar

   • commons-codec-1.3.jar

   • commons-collections-3.1.jar

   • commons-discovery.jar

   • commons-logging.jar

   • dom3-xml-apis-2.5.0.jar

   • jai_imageio.jar

   • jaxen-1.1-beta-9.jar

   • jaxrpc.jar

   • log4j.jar

   • mail.jar

   • saaj.jar

   • wsdl4j.jar

   • xalan.jar

   • xbean.jar

   • xercesImpl.jar

   These JAR files are in the [install directory] /Adobe/LiveCycle9/sdk/lib/thirdparty directory.
