How to use the J2SE Adapter Engine:
The J2SE AE aka “Adapter Engine (Java SE)” is still supported and being maintained by SAP. You can use it if you need a light-weight middleware component on any system close to database, JMS queue, WebService or NFS filesystem.
Mainly it is used to solve the UNIX-Windows NFS dilemma (you want to access a network drive but your PI/PO installation is in UNIX).
Another network/security use case is to install it into the DMZ and use the J2SE AE as a reverse proxy (application gateway) for inbound communication from the internet.
Here you go:
- Get J2SE software from SAP (Service Marketplace Alias /swdc -> Support Packages and Patches-> Browse -> SAP NetWeaver and complementary products -> SAP NetWeaver -> SAP NETWEAVER 7.4 -> Entry by Component -> PI Adapter Engine (Java SE) => Downoad XI CONNECTIVITY SE 7.40
- Download JRE (e.g. from http://www.oracle.com/technetwork/java/index.html according to the required version) – Java 7 works fine
- Install JRE and extract AE archive into file system (only archive com.sap.xi.techadapters.sda is needed)
- Copy file servlet.jar (can be downloaded e.g. from http://www.java2s.com/Code/Jar/s/Downloadservletjar.htm) into extracted folder tech_adapter
- Install Service under Windows/Unix (use admin rights “run as administrator” when executing the script)
- Start the Admin UI from Browser with default port 8200 and user sap password init
- Configure the channels you need and communicate via HTTP(S) to your PI/PO integration server
Btw: This approach basically exists since XI 2.0 and is still valid for PI/PO 7.5! See the official documentation: SAP Help.
