How to set parameter to invoke EJB
My EJB Business interface is as follows:

public interface HelloWorldBI{
String sayHello(int num, String s) throws IOException;
}
My servicemix.xml is as follows:

My EjbHttpBridge.java is as follows:
-----------------------------------
public class EjbHttpBridge extends TransformComponentSupport implements
MessageExchangeListener{
protected boolean transform(MessageExchange exchange, NormalizedMessage
in, NormalizedMessage out) throws MessagingException {
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange01.
exchange.getService() = " + exchange.getService());
NormalizedMessage copyMessage = exchange.createMessage();
getMessageTransformer().transform(exchange, in, copyMessage);
Source content = copyMessage.getContent();
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange02.
content = " + content);
String contentString = null;
if (content instanceof DOMSource){
contentString = node2XML(((DOMSource) content).getNode());
System.out.println("EjbHttpBridge(" + name +
").onMessageExchange03. contentString = " + contentString);
}
QName qName = new QName("http://servicemix.apache.org/demo/",
"jsrEjbEP");
InOut inOut = createInOutExchange(qName, null, null);
NormalizedMessage normalizedMessageIn = inOut.createMessage();
normalizedMessageIn.setContent(new StringSource(contentString));
inOut.setInMessage(normalizedMessageIn);
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange04.
End");
sendSync(inOut);
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange05.
End");
NormalizedMessage normalizedMessageOut = inOut.getOutMessage();
NormalizedMessage copyReturnMessage = exchange.createMessage();
getMessageTransformer().transform(exchange, normalizedMessageOut,
copyReturnMessage);
Source contentReturn = copyReturnMessage.getContent();
String contentReturnString = null;
if (contentReturn instanceof DOMSource){
contentReturnString = node2XML(((DOMSource)
contentReturn).getNode());
System.out.println("EjbHttpBridge(" + name +
").onMessageExchange06. contentReturnString = " + contentReturnString);
}
out.setContent(new StringSource(contentReturnString));
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange07.
End");
return true;
}
}
My contentString is as follows:
-------------------------------
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

<intVal xsi:type="xsd:int">4</intVal>
<string xsi:type="xsd:string">A</string>
</m:sayHello>
</env:Body>
</env:Envelope>
Things are fine, and I get contentReturnString as follows:
----------------------------------------------------------
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<result xsi:type="xsd:string">This message brought to you by the
letter A and the number 4</result>
</m:sayHelloResponse>
</env:Body>
</env:Envelope>
My servicemix console is as follows:
------------------------------------
EjbHttpBridge(1).onMessageExchange01. exchange.getService() =

EjbHttpBridge(1).onMessageExchange02. content =

EjbHttpBridge(1).onMessageExchange07. End
***************************************************
Now, I change my EjbHttpBridge.java as follows:
-----------------------------------------------
public class EjbHttpBridge extends TransformComponentSupport implements
MessageExchangeListener{
protected boolean transform(MessageExchange exchange, NormalizedMessage
in, NormalizedMessage out) throws MessagingException {
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange01.
exchange.getService() = " + exchange.getService());
QName qName = new QName("http://servicemix.apache.org/demo/",
"jsrEjbEP");
InOut inOut = createInOutExchange(qName, null, null);
NormalizedMessage normalizedMessageIn = inOut.createMessage();
//normalizedMessageIn.setContent(new StringSource(contentString));
normalizedMessageIn.setProperty("intVal", new Integer(1));
normalizedMessageIn.setProperty("string", "a");
inOut.setInMessage(normalizedMessageIn);
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange04.
End");
sendSync(inOut);
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange05.
End");
NormalizedMessage normalizedMessageOut = inOut.getOutMessage();
String result = (String) normalizedMessageOut.getProperty("result");
System.out.println("EjbHttpBridge(" + name + ").result = " +
result);
out.setContent(new StringSource(result));
System.out.println("EjbHttpBridge(" + name + ").onMessageExchange07.
End");
return true;
}
}
Note:

Now my aim is to EXPLICITELY SET parameters to invoke EJB.

NB:

My XML message here is just to trigger the flow, and not for EJB as
parameters. This note is just to avoid confusion.
MY QUERY:
---------
I have seen http://www.nabble.com/Passing+parameters-t1679729.html. Still I
have doubt how to explicitely set parameters and/or operations to invoke an
EJB.

Re: How to set parameter to invoke EJB
Posted by Guillaume Nodet <gn...@gmail.com>.
If you are trying to send parameters using properties, it will not work,
because the jsr181 component does not handle properties, just the xml
content.
The NullPointerException is due to the fact that you do not set a valid
content
in the input message (this is mandatory).
If you want to send parameters to your EJB programmatically, you will have
to build the xml request manually.
Another way would be to use a java proxy for your EJB business interface
that would send request on the JBI bus. See
org.apache.servicemix.jsr181.xfire.JbiProxy.
Cheers,
Guillaume Nodet
