Java stack and ICM


Does the Java stack always receive requests via web protocols?

Can it receive requests via DIAG as the ABAP stack does?

When the Java stack receives web requests, does it always go through the ICM first, or can the dispatcher receive web requests directly?

In a configuration where there is a Java stack and an ABAP stack configured, is the ICM always required to differentiate between ABAP web requests and Java web requests?

Kind regards,

Hello Peter,

1. java communication is working via http or https. as far as I know, that's it.

2. java can recieve requests from an ABAP system if you have a gateway in between - in case you have a standalone java system, you need to install a standalone gateway or use a gateway of an ABAP system.

3. java goes through ICM if it's part of a double stack installation. if you have a java only system, there's no ICM it could use, but if you have a double stack system, you'll definetly need the ICM.

hope that helps.

Best regards
