Hello, I have a question about ESS, mySAPERP 2005 and Portal. We installed on one server a mySAP ERP 2005 (only AS-ABAP) and on a second server a Portal (with AS-JAVA, XSS, EP...). Some guys told me, that I have further to install a Java-Addin on th mySAPERP 2005 Server for the ESS-Deployment. Is that true? In my opinon the whole deployment could be done in the Portal.
