Re: JCA on Web server

Hi,

1. JCA is a specification for building a connector for any ERP, while JCO is
SAP specific API for communication with SAP. You can use JCO to communicate
with SAP but if you want to use JCA, you have to select a resource adapter
implementating the JCA specification.

2. JCA task about manage and non-manage environment both. So, a JCA adapter
can be used in a web server also.

3. Best practice is to use manage environment ie using JCA adapter deployed
in an application server.

4. You will get examples with the adapter component that you want to use.

Regards.
Manish.

Subject: JCA on Web server


To anyone who may advice:
    I am currently evaluating the feasibility of integration between a web-
based application (written in JSP and running on Jakarta Tomcat) and SAP
system, in which, I will only want to 'download' data from SAP.
    I have searched in the Internet and found that there are few
architectures that could help me in achieving the objective. However, I am
confused and would like anyone who may advice to clear my following doubts:
1) What is the differences between J2EE Connector Architecture (JCA) and SAP
Java Connector (JCO)?
2) Does J2EE Connector Architecture really need to be implemented on an
application server? In order words, can I achieve the above objective by
using JCA but still running the system on web- server (particularly Jakarta-
Tomcat)
3) What is the best practice to develop such a system (to achieve the above
objective)?
4) Any good examples/ references (including source code/ demo page) that I
could refer to?
     Thanks.
