Handler to add HTTP headers to HTTP request not invoked when using Axis Client API

Question

I am using the Axis API to access Axis HTTP server. The documentation of the API can be found here.

I am using the following code to add handlers to the server.

Answer 1

Okie. This should do the trick :

1 - Create a wsdd file (say /tmp/test.wsdd) containing this :

2 - Ensure all axis libs are in your class path and then run :

java org.apache.axis.utils.Admin client /tmp/test.wsdd

3 - Step 2 will generate a client-config.wsdd. Copy this to your project and ensure it will be in the class path when the project is run.

4 - ALL webservice calls (via Http transport) will route via the TestHandler1 class

Here is my TestHandler1 class (a slight modification of ur handler to access the MIME headers) :

package axistest;

import javax.xml.namespace.QName;
import javax.xml.soap.MimeHeaders;
import org.apache.axis.AxisFault;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;

public class TestHandler1 extends BasicHandler {

@Override
public void init() {
    System.out.println("init called");
    super.init();
    System.out.println("init called");
}

@Override
public void cleanup() {
    super.cleanup();
    System.out.println("cleanup called");
}

@Override
public void invoke(MessageContext mc) throws AxisFault {
    System.out.println("invoke called");
    System.out.println("=----------------------------------=");
    MimeHeaders mimeHeaders = mc.getMessage().getMimeHeaders();
    mimeHeaders.addHeader("X-Test", "Hello");
    System.out.println("Headers : \n " + mimeHeaders);
}

public QName[] getHeaders() {
    System.out.println("getHeaders");
    return new QName[1];
}

}

when I run this on my box, I see that these handler methods are being invoked :

- Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.
init called
init called
invoke called
=----------------------------------=
Headers : 
 org.apache.axis.message.MimeHeaders@761eec35
