[EJB/JBoss] - (Urgent)Query regarding HttpRouter/JBR-provider - jboss-user

Sunday, 6 April 2008

Hi,

I am writing an application in JBossESB.
Environement:
=========
JBoss Application Server -4.2.2.GA
JbossESB 4.2.1GA

I am using jbr-provider for http protocol support. I have to route the http request to a
servlet from JBossESB. To achieve this I have written below configuration. Regarding the
component used in the configuration I have few questions:

Question 1:
=======
Does HttpRouter supports only OneWay communication? As per the java code of HttpRouter
class (Line No 113) the message returned by the class is always null. How can I get the
response back sent by the URL called?

Question2:
=======

It seems that jbr-provider have support for the data sent by Http POST method only as the
body of message is null in case of GET request and Exception is thrown. 
Is so what is the way to handle data sent by GET Request?
Exception is given below:

Question:
=======
Is there any other router class to invoke a request to a Servlet in RequestResponse mep?
