i am sorry, i don't know jca too much.
but i think the below code may be a little help to you.

package org.xfree.url;

try {

con.setDoOutput(true);
BufferedReader reader =3D new BufferedReader(new InputStreamReader(

Hi again,
Since I did not receive any reply I thought to send another email with the =
additional re-search I did. Basically from the diagram on slide five (5) of=
the presentation 'Java=E2=84=A2 EE Connectors Demystified' by Binod P.G, G=
eorge Tharakan, Sivakumar Thyagarajan it is clear that a custom connector s=
hould be able to invoke a deployed servlet.
Having said that I still cannot understand how this can be done. In the doc=
ument 'J2EE=E2=84=A2 Connector Architecture Specification' there is a whole=
chapter on how to invoke an EJB (Chapter 13) however I cannot find anythin=
g about Servlet Invokation. I also downloaded the Servlet Specification doc=
ument but cannot really map the two together (probabbly due to my little kn=
owledge about the subject). I have also checked how the Http Connector of T=
omcat works and here I found out that the Tomcat when loaded the Http Conne=
ctor will provide an Adapter in order to invoke Servlets however do not kno=
w if this is also the case for a JEE Application Server, nor do I know if I=
have to set some extra configuration to have such an object available.
Thanks and Regards,
Simon J. Aquilina

Subject: Is it possible for an inbound connector to invoke servlet?

Hi,
I am not sure if this is the right place to ask this question. My question =
is related to inbound connectors. From what I can understand an application=
server will start a Resource Adapter (RA). Then when a Message Driven Bean=
(MDB) is deployed the related RA are informed. The RA would then create an=
Endpoint Consumer. When a message is received from an EIS the Endpoint Con=
sumer will call a method from the MDB.=20
Now my plan was to develop something similar to the http protocol. The Ente=
rprise Information System (EIS) makes a request, the request is processed, =
and a response is returned in XML (or format understood by the EIS). Becaus=
e of this similarity I was wondering; Is it possible that an inbound connec=
tor invokes a deployed servlet?=20
Thanks and Regards,
Simon J.
