Regarding Message Inflow of JCA 1.5

[yogs]

Hi,

I'm new to JCA and i read the JCA 1.5 specification. It says that JCA 1.5 supports Message Inflow(i mean it supports to invoke EJB from EIS via resource adapter). Now i wants to clear one thing. That is,
is it possible to return the data from EJB to calling point of EIS?.

If not, please suggest me an alternate way to achieve this using JCA 1.5 .

Because according our requirements of EAI, EIS is expecting result after calling EJB(which is in application server).

Thanks in advance.

No, inflow is for one-way communication. JCA is about making EIS resouces available to J2EE components, not the other way around. For that the EIS integration would use the standard J2EE client apis.

If you read the spec, you will see that the message interface can be anything you like
including having a return value
e.g.

public interface MyMessageListener
{
ReturnType onRequest(MyRequest request);
}

Also with jca 1.5 it is possible for a resource adapter to invoke either directly
or using the workmanager (if you want transaction inflow) on an EJB (e.g. an SLSB)

NOTE: Being a newbie does not excuse you from reading the specs before posting
frivilous questions. We are not here so you don't have to do your own work.

Hi,

Here is a good example of inbound resource adapter.

I have executed it and it works fine.

Here is another for outbound resource adapter.

Hope this helps.

Thanks
