Connecting to SAP via JCO

[Steve Winer]

I am trying to connec to SAP using the JCO.createClient method and I can't get past this error:
java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
/home/sxw29/jco/libsapjcorfc.so: ld.so.1: /vol/java/1.3.1/jre/../bin/../bin/sparc/native_threads/java: fatal: librfccm.so: open failed: No such file or directory
I am setting the java.library.path system property during server startup to point to directories with libsapjcorfc.so and librfccm.so. I am also pointing to /usr/lib to have ld.so.1 in the path as well, but I still get the above error. Does this error indicate that ld.so.1 or librfccm.so can't be found? Any ideas why not if they are in the path?

what you need is a shared libraray
it is like
---> means direction of calling
java ---> shared libraray( either .dll or .so)---> ABAP
you need include this .so file
and set library path
