Accessing SAP backend from j2ee without entrprise portal

Hi All,

I have a requirement which is migrating the applications hosted on tomcat server to SAP web AS and accessing the SAP ERP system from the web application.As of now i have two options one is importing the web application into NWDS and creating a webdynpro application or creating j2ee application.

<b>Now my doubt is how do i access sap ERP system from the application(I dont have any enterprise portal which should have made my job easy by creating JCO destinations and accessing them in the webdynpro application)</b>

Please let me know how to access backend from j2ee or webynpro from NWDS without Enterprise portal




Hi Bala,

As you said you're mingrating applications from tomcat to WebAS, I can safely assume you're dealing with pure J2EE applications.

Converting these applications to WebDynpro, reworking them entirely, just to access ERP system is not necessary. I'm sure that'll be a big project in itself and not suggested in business terms (unless you are just experimenting and on a learning curve).

In my opinion, if you want to stick with the existing j2ee applications with minimum coding possible to work with ERP (to call RFCs and BAPIs), the best way to go about is to use plain JCO. This api lets you make calls to RFCs and BAPIs, more like using JDBC.

Hope that's an insight.
