Connection reuse/sharing with Java web app and EP?

[ChrisSolomon]

Is it possible for a Java web application (not Webdynpro based) that is to be used in the portal to "poll" the open connections a user has to backend systems and then use an open connection if one is found that meets the need? If so, what APIs/Classes are exposed in the portal to allow this? Any short example code of doing this?

Thanks in advance!

Hallo.

In my NWDS I develop an application that I will deploy on EP 7.4 and I want to use a “JCO RFC Destination” that I define from the portal to an ABAP backend.

How could I do this in the java code?

I always find example on “Jco connector” standalone (sapjco 2.x and 3.x) but no example if I want to use a  “JCo RFC Provider: JCo RFC Destinations”

Could you help me?

Thanks a lot for your help.

How about the SAP System Connector, i am guessing this is pretty much what you need, see:

For clarification...this will NOT be a Webdynpro application. So then, will this still work? Is this something as simple as using the Pool Manager of the JCO? Would this have the same result?

Hi,

JCO Destinations can be used in webdynpro and java application because Destination service is a generic service hosted on the EP server.

In the approach suggested by Markova the SAP system will be created in System Administrator-> System Configuration -> Landscape configuration and the system can be used in the portal applications and j2ee applications.

Hope that helps.

Hi,

Destination service can be used to connect to the backend systems. The RFC destinations should be configured in the Webdynpro destination area.
