[Axis2] synchronous dual channel blocking service invocation failed with error "Unable to engage module : addressing"

[Ashish Soni]

Hi,

I am trying to write "synchronous dual channel blocking service
invocation." client code.

While running the code i am getting the error:
"org.apache.axis2.AxisFault: Unable to engage module : addressing

value.addChild(factory.createOMText(value, "Ashish Soni"));
method.addChild(value);

Options options = new Options();
options.setTo(targetEPR);
options.setUseSeparateListener(true);
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);

client.engageModule(Constants.MODULE_ADDRESSING);
client.setOptions(options);
OMElement result = client.sendReceive(method);

StringWriter writer = new StringWriter();

axisFault.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
try {

} catch (AxisFault axisFault) {

}
}
}

Is any specific setup is required to run the client code.

Did you engage the addressing module at the client and at the server?

The second thing is to then think about how a server can call back the proper client.
This information must go to the server on initial call and that is why addressing is needed on either side.

Make sure you have addressing module in the class path or create client
with client side repository.
