Using KnowledgeTree SOAP Services from Java apps

Jan 21, 2010

I'm making a front-end to KnowledgeTree using the ZK Ajax framework so I eventually dipped my fingers into KT's web service integration from a Java app. My previous SOAP projects involved a Tcl client and a Google gadget using the javascript/php combo.

KnowledgeTree's wiki article on Web Service integration using JavaBeanshell interpreter to execute the Java code, I also modified the tester client application accordingly.

What's needed:
has been most helpful. Since I'm doing my development work on Windows, I've adapted the procedures slightly. And since ZK uses the

The proxy classes were generated using the WSDL2Java utility provided by the Apache Axis. I'm providing the packaged ktws.jar available for download here. To generate the proxy classes yourself, you would need the Java Compiler and not just the JRE. Here's the batch file to generate the jar package.

set CP=axis-1_4/lib/axis.jar;axis-1_4/lib/commons-discovery-0.2.jar
set CP=%CP%;axis-1_4/lib/commons-logging-1.0.4.jar;axis-1_4/lib/jaxrpc.jar
set CP=%CP%;axis-1_4/lib/log4j-1.2.8.jar;axis-1_4/lib/saaj.jar
set CP=%CP%;axis-1_4/lib/wsdl4j-1.5.1.jar
java -cp %CP% org.apache.axis.wsdl.WSDL2Java -c T1 -p com.pipoltek.ktws http://docs.pipoltek.com/ktwebservice/webservice.php?wsdl
"%JAVA_HOME%\bin\javac" -d . -classpath %CP% com/pipoltek/ktws/*.java
"%JAVA_HOME%\bin\jar" cvf ktws.jar .\com\pipoltek\ktws\*.class

Here's the Beanshell script to execute a login via SOAP.

/*
filename: ktsoaptest.bsh
to run, type from the command-line:
java -cp bsh-2.0b4.jar bsh.Interpreter ktsoaptest.bsh
*/

// add axis classes
addClassPath ("./axis-1_4/lib/axis.jar");
addClassPath ("./axis-1_4/lib/axis-ant.jar");
addClassPath ("./axis-1_4/lib/jaxrpc.jar");
addClassPath ("./axis-1_4/lib/commons-logging-1.0.4.jar");

addClassPath ("./axis-1_4/lib/saaj.jar");

// knowledgetree proxy classes
addClassPath ("./ktws.jar");

// others
addClassPath ("./lib/activation.jar");
addClassPath ("./lib/mail.jar");

import com.pipoltek.ktws.KnowledgeTreeBindingStub;
import com.pipoltek.ktws.Kt_response;
import com.pipoltek.ktws.Kt_folder_contents;
import com.pipoltek.ktws.Kt_workflow_transitions_response;
import org.apache.axis.client.Service;
import java.net.URL;
import com.pipoltek.ktws.Kt_folder_item;

URL url = new URL("http://kt352c.pipoltek.com/ktwebservice/webservice.php");

KnowledgeTreeBindingStub stub = new KnowledgeTreeBindingStub(url, new Service());

System.out.println("Logging into KnowledgeTree");
Kt_response response = stub.login("rexjun","cabanilla","127.0.0.1");

int status_code=response.getStatus_code();
String session;
if (status_code == 0) {
session = response.getMessage();
System.out.println("Session: " + session);
} else {
System.out.println("Status Code: " + status_code);
System.out.println("Session: " + response.getMessage());
return;
}

I'll be using this piece of code to invoke SOAP services from my ZK app. More on this later..
