This is my memo for quick reference to install SAP Java Connector 3(SAP Jco3) on tomcat in linux system.

I use RHEL5,tomcat6,sapjco3. Here are simple step.

1. Check your java version, SAP Jco3 require JRE 1.5 or 1.6

2. Download latest SAP Java Connector from select package that match your hardware. In my case,package for linux on intel x86 is sapjco3-linuxx86_64-x.x.x.tgz

3. extract file to sapjco-installation-path like /opt/sapjco3

4. add your sapjco-installation-path to environment variable LD_LIBRARY_PATH.

5. add your sapjco-installation-path/sapjco3.jar to environment variable CLASSPATH.

restart tomcat. That's it.

If you migrate from sapjco2 to sapjco3 you have to adapt your code by read this migration guide:
