Java Code Sinppet: JAX-WS & MTOM

To enable MTOM (Message Transmission Optimization Mechanism) there are several things need to be done and in a nutshell

1. add the MTOM annotation on the services class

@javax.xml.ws.soap.MTOM
    @WebService(serviceName =

2. Following table list the relationship between MIME type and java type

MIME type          Java type
image/gif          java.awt.Image
image/jpeg          java.awt.Image
text/plain          java.lang.String
text/xml          javax.xml.transform.Source
application/xml  javax.xml.transform.Source
*/*                  javax.activation.DataHandler

3. Edit the WSDL to and list the correct mime type which will change the schema from

<xs:sequence>
    <xs:element name="return" type="xs:base64Binary" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>

to

<xs:sequence>
    <xs:element name="return" type="xs:base64Binary" minOccurs="0" maxOccurs="unbounded" 
xmime:expectedContentTypes="image/jpeg" xmlns:xmime="http://www.w3.org/2005/05/xmlmime"/>
</xs:sequence>

4. Make the container use the edited WSDL than generated one

@WebService(serviceName = ...., wsdlLocation="WEB-INF/wsdl/edited.wsdl")

5. Deploy the new service

for more info netbeans tutorial pages 1, page 2, page 3



To do the above without any modification to wsdl (using annotation on the java class)

1. Set the @MTOM as above on the service

@MTOM
@WebService
public class NewWebService {

2. Annotate the data type on the web method as follows

@WebMethod
public void setImage(@XmlMimeType("image/gif")Image img){

3. Can also annotate a return type

@WebMethod
public @XmlMimeType("image/gif")Image getImage( String name){

4. All kind of data types could be used

@WebMethod
public @XmlMimeType("*/*")Image getFiles

Java Code Sinppet: OWL Demo with SWRL

In the classpath :

protege.jar

and every jar in the

Protege_3.4\plugins\edu.stanford.smi.protegex.owl

directory

public class OWLDemo {

    public static void main(String[] args)  {
        try {
            String uri = "file:///C:/MSC/project/old/travel.owl";
//            String uri = "http://localhost:8080/owl/travel.owl";
            OWLModel owlModel = ProtegeOWL.createJenaOWLModelFromURI(uri);
            OWLNamedClass classs= owlModel.getOWLNamedClass("Trade_Association");

            Collection c =  classs.getNamedSubclasses();
            Iterator itr = c.iterator();
            
            while(itr.hasNext()){
                OWLNamedClass cc = (OWLNamedClass) itr.next();
                System.out.println(cc.getNestedBrowserText());
                System.out.println(cc.getName());
            }

           SWRLFactory factory = new SWRLFactory(owlModel);
           // factory.replaceImps(owlModel); // to run the same query again uncomment
           SWRLImp imp = factory.createImp("Query-2", "Use_Inconjunction_With(?x, ?y) -> sqwrl:select(?x, ?y)");

           SWRLRuleEngineBridge bridge = BridgeFactory.createBridge("SWRLJessBridge", owlModel);
           bridge.infer();
           SQWRLResult result = bridge.getSQWRLResult("Query-2");
                    while (result.hasNext()) {
                      System.out.println("X: " + result.getObjectValue("?y").getIndividualName());
                      System.out.println("Y: " + result.getObjectValue("?x").getIndividualName());

                      result.next();
                    } 

        } catch (Exception ex) {
            
        }

    }

}
