Resolution

SAP libraries are probably missing.

Download them from internet.

Example on Linux :

* Copy the connector library sapjco3.jar to ${CORE_LOCAL}/java/lib/ext
* Copy an additional library sapidoc3.jar to ${CORE_LOCAL}/java/lib/ext
* Copy the shared library libsapjco3.so to ${CORE_LOCAL}/load
* Add the following entry to CLASSPATH in ${CORE_LOCAL}/config/environment.dat:  ${CORE_LOCAL}/java/lib/sapjco3.jar:${CORE_LOCAL}/java/lib/sapidoc3.jar
