Axis2 Http Header

[ethan james]

Hi All,

I am new to Axis2 and Webservices. Would someone know how to add key-valye in http header using axis 2 generated stubs?
I was looking for a method like httpheader in stub._getServiceClient() but cant find one.

Any help is appreciated,

Thanks

[shivendra tripathi]

Try adding it in message context. I tried code mentioned below and was able to see http headers in TCP monitor.

   
MessageContext mc = new MessageContext();
		mc.setEnvelope(getEnvelope());
		res.addMessageContext(mc);
		List headers = new ArrayList();  
	      headers.add(new Header("http_header1","value1"));
	      headers.add(new Header("http_header2","value2"));
	      mc.setProperty(HTTPConstants.HTTP_HEADERS, headers);

 

[ethan james]

res.addMessageContext(mc)

Sorry for my ignorance, but what actually
is "res"?

[shivendra tripathi]

res is referring to OperationContext, though it's not a good naming convention. I would have referred it with oc

[ethan james]

Hi Shivendra,

I did something like:

OperationContext operationContext = stub._getServiceClient().getLastOperationContext();
MessageContext mc = new MessageContext();
mc.setEnvelope(mc.getEnvelope()); // where to retrieve the getEnvelope()?
operationContext.addMessageContext(mc);

List headers = new ArrayList();
headers.add(new Header("http_header1", "value1"));
headers.add(new Header("http_header2", "value2"));
mc.setProperty(HTTPConstants.HTTP_HEADERS, headers);
operationContext.addMessageContext(mc);

This is from the client side, but its throwing an error, am i doing something wrong?

Thanks

[shivendra tripathi]

I can help you only if you can post the stack trace of the error.

[ethan james]

Hi Shivendra,


OperationContext operationContext = stub._getServiceClient().getLastOperationContext();
MessageContext mc = new MessageContext();
mc.setEnvelope(mc.getEnvelope());
operationContext.addMessageContext(mc); // this line throws java.lang.NullPointerException


INFO [org.apache.axis2.deployment.ModuleDeployer] Deploying module: metadataExchange-1.5 - file:/home/developer1/Desktop/lib/mex-1.5.jar
java.lang.NullPointerException


Hope you can help.

Thanks

[shivendra tripathi]

Can you provide your stub code and complete stack trace of the error? And some details about what are you trying to do? If you are doing wsdl2java please provide your wsdl.

Thanks

Hi Shivendra,

I am trying to put username/password into Http, though it might not be the correct implementation, just want to know that it can be done.

This is my server code:


import java.util.Map;
import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.handler.MessageContext;
import org.jboss.seam.annotations.Name;

@Stateless
@Name(value="HelloWorldAuthenticateImpl")
@WebService
public class HelloWorldAuthenticateImpl implements HelloWorldAuthenticate {

@Resource
WebServiceContext context;

@WebMethod
public String greeting(String name) {
if (!authenticated())
return null;
return "Welcome, " + name;
}


private WebServiceContext getContext() {
return context;
}


private boolean authenticated() {

MessageContext mCtx = getContext().getMessageContext();
Map httpHeaders = (Map) ((Map<String, Object>) mCtx).get(MessageContext.HTTP_REQUEST_HEADERS);
List uList = (List) httpHeaders.get("username");
List pList = (List) httpHeaders.get("password");

if (uList.contains("myusername") && pList.contains("mypassword"))
return true;

return false;
}
}

This is my client code:


import java.rmi.RemoteException;
import java.util.ArrayList;
import java.util.List;
import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.context.OperationContext;
import org.apache.axis2.transport.http.HTTPConstants;
import org.apache.commons.httpclient.Header;

public class HelloWorldTest {

public static void main(String[] args) throws Exception {

try {
HelloWorldAuthenticateImplServiceStub stub =
new HelloWorldAuthenticateImplServiceStub();
getGreeting(stub);

}
catch (Exception e) {
e.printStackTrace();
}
}

public static void getGreeting(HelloWorldAuthenticateImplServiceStub stub)
throws AxisFault {
HelloWorldAuthenticateImplServiceStub.GreetingE req =
new HelloWorldAuthenticateImplServiceStub.GreetingE();

HelloWorldAuthenticateImplServiceStub.Greeting param =
new HelloWorldAuthenticateImplServiceStub.Greeting();
param.setArg0("ETHAN");

req.setGreeting(param);

HelloWorldAuthenticateImplServiceStub.GreetingResponseE res = null;

OperationContext operationContext = stub._getServiceClient().getLastOperationContext();
MessageContext mc = new MessageContext();
mc.setEnvelope(mc.getEnvelope());

List headers = new ArrayList();
headers.add(new Header("username", "myusername"));
headers.add(new Header("password", "mypassword"));
mc.setProperty(HTTPConstants.HTTP_HEADERS, headers);
operationContext.addMessageContext(mc);

try {
res = stub.greeting(req);
}
catch (RemoteException e) {
e.printStackTrace();
}
HelloWorldAuthenticateImplServiceStub.GreetingResponse greeting =
res.getGreetingResponse();
System.out.println(greeting.get_return());
}
}

And this is my wsdl:

I asked for your stub code because following line is creating problem.

 OperationContext operationContext = stub._getServiceClient().getLastOperationContext();    

And since getLastOperationContext() is not part of axis API my assumption is, we need to make some changes in this. As name suggest it return you the last OperationContext but if this is your fist operation then what? I guess it will return null and that is what happening here. It will be good if you post your stub and code related to creation of operation context.

I didn't find implementation of

 OperationContext operationContext = stub._getServiceClient().getLastOperationContext()   

_getServiceClient() and getLastOperationContext() in the code you posted. Which I was interested to see.

[Ulf Dittmer]

Ethan,
nobody is going to read through all that code. Firstly, it's much too much - you probably need to remove at least 90% of it to make it more palatable to people. Secondly, being unformatted, it's essentially unreadable - please UseCodeTags. If you edit your post to address these two issues you have a much better chance that someone will try to understand it.

[Claude Coulombe]

Greetings,

=> to add SOAP headers to WS using stub generated by Axis2

MyGeneratedStub clientStub = new MyGeneratedStub(...);
ServiceClient serviceClient = clientStub._getServiceClient();
QName qname = new QName("namespaceURI","localPart","prefix");
serviceClient.addStringHeader(qname, "value");

=> to add HTTP header to the WS request using stub generated by Axis2

You need well defined MessageContext (not null) so you could modify the stub code (for instance MyGeneratedStub.java) using addHttpHeader method

this.addHttpHeader(_messageContext, "Your header name", "Your header value");
