I am trying to write a program that access Borland's Caliber RM using the
product's Java API.

I imported the relevant class libraries in JBuilder through the Project
Properties.Paths.Required
Libraries tab.

All meaningful code in the app is copied from the documentation distributed
with the Caliber RM.

I'm getting the error message java.lang.UnsatisfiedLinkError: no jvb in
java.library.path when the program gets to listProjects.

But have no idea what this error means.  The complete code and full error
message trace are below.

Thanks

The problem is that the ClassLoader cannot find the native library named
"jvb".  Where it looks depends on the host operating system.  For Windows,
it should be in the file "jvb.dll" and for Linux/Unix it should be in the
file "libjvb.so".  The directories searched are the usual ones for the
host operating system.  However, note that the "directory that contains
the program file" is the one that contains the launcher executable, not
the class file.
