Scenario 6: Installing/porting JCo to other operating systems

Porting to other platforms
JCo performs wonderfully well on many UNIX-like and UNIX-flavored platforms. This installation is somewhat simpler, but seems to confuse most people not familiar with a UNIX environment. Should you encounter one of the previous installation exceptions there are only two things you need to check:

- Appropriate environment variable points to JCo installation directory: Depending on the platform, the name of the environment variable will be LD_LIBRARY_PATH (Linux, Sun Solaris, HP Tru64), LIBPATH (IBM AIX), SHLIB_PATH (HP-UX,) or DYLD_LIBRARY_PATH (Mac OS X). This variable should be set to the directory in which you installed the JCo connector. If you are running JCo within an application server, ensure that the application server can "see" OS-level environment variables.

- CLASSPATH contains sapjco.jar: The CLASSPATH environment variable must contain an explicit listing that points to both the directory and sapjco.jar filename. Again, ensure that the CLASSPATH variable is also configured appropriately within your Java application server.
