Download some sample Java code for your BAPI programming efforts.

The attached ZIP file includes Java proxies generated with VisualAge for Java (VAJ), a demo implementation using VAJ proxies, Java proxies generated with SAP Assistant, a demo implementation using SAP Assistant proxies, and VAJ Access Builder for SAP R/3 runtime libraries.

The zip files should be extracted to the same location. RFC library (required for a connection to R/3) is not included. You can obtain RFC library by downloading and installing SAP Automation V4.5A. However, you will need SAP Automation V4.5A for the demo application anyway. Please make sure to back up an existing librfc32.dll file before copying librfc32.dll to your system directory. SAP Automation 4.5A is now available as a patched and fixed version. The patch file mentioned in readme.txt will no longer be required. While it is no longer available for download from SAP Labs, SAP Automation is included on (older) installation CDs such as the mySAP GUI 4.6D CD. For further information, please refer to the included readme.txt file.
