Needs Opinoin regarding JCA Framework from ERP proffesionals?
Hi,
I have read in the docs that the JCA framework will enable our application to get integrated with the already existing EPR (Siebal,PeopleSoft etc).I have not worked on these giant ERP pakages but have an idea about the webbased ERP and CRM systems.I wanted to know how the adapters defined for particular Appserver will connect to the already existing ERP's and what does this mean?
As per my understanding these giant names like SAP,Siebal,PeopleSoft does have the database and the bussiness logic which will fit for the company using it,I mean the SAP implementor would have configured the ERP after undestanding the bussiness needs of the Company.
Now once we say that the JCA framework will connect to the ERP does it mean we will be able to get the data already present in these ERP and the frontend have to be developed again(I mean all the JSP) for making it web (browser-user agent ) enabled...
Hope to get the corrections on this from the professionals
regards vicky

You can write your own JCA resources, wrapping the ERP code yourself or buy a JCA resource from the ERP vendor. To quote from J2EE Connector Architecture and Enterprise Application Integration, Sun Press - " software vendors like PeopleSoft, Siebel, SAP, and many others are working to deliver standard JCA adapters for their enterprise suites", so they may or may not be on the market already.
Theoretically, a JCA resource adapter should work on any app server.
As for redeveloping the front end, I'm afraid I don't know, but I'm sure someone else will.

I did not undestand by this,what do you mean by writing JCA resources?
As per my logical understanding these giant ERP packages will be configured as per the company needs and they may be having there own database,so if I require the data available in the ERP package I should be able to get the connectivity to its database.Is JCA Adapters used for getting the data from the ERP data repository or some thing of that sort.

How you will define the adapter to the layman?
Thanks for reply....

Probably meant a JCA compliant resource adapter implementation.

Whereas I'm sure the links stevew2 provided cover the answer to these questions, here it is in layman's terms...
A JCA compliant resource adapter is simply an implementation of interfaces that allow J2EE applications to have access to data in an EIS (ERP systems are an example of an EIS). You can write your own RA, or they can be implemented and distributed by the ERP vendor. Once you have installed the adapter, your J2EE applications can have access to the data stored in the ERP, similar to the way they could use JDBC to access data in a database.
