Generate Java proxy for RFC

85 Views

Hi

I'm new - sorry if this is a simple question.

I'm developing a jsp on Oracle Application server, and I want to call a function in R/3 which i've written in ABAP. I tried using JCo with the sapjcorfc.dll and sapjco.jar. Works fine in development environment, but in production I get "sapjcorfc.dll already loaded in another classloader" error. To solve this I found a note saying that generating a proxy should be the solution. So I downloaded SAP NetWeaver in order to get the Development studio, and the tried to follow these instructions:

which leads to:

First step is to Choose:

File -> New -> Other -> SAP Connectivity -> SAP Enterprise Connector

BUT - i don't get an option called SAP Connectivity. I've browsed all menus and can't find anything that has to do with proxy generation.

Any help will be appreciated.
