java.lang.UnsatisfiedLinkError: no jvb in java.library.path

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.

java.library.path is where java finds system-dependent things like .dll
files on Windows and .so files on *nix boxes.

Caliber seems to have a need for a file called jvb.dll on Windows.
You'll need to find it, and then set your java.library.path to point to
a directory that contains that file.

I'd be surprised if this isn't in the Caliber SDK docs...

This is a VERY common problem with the Caliber SDK. Probably 20% of the
posts in that forum are about this problem.

In JBuilder, go to the runtime configurations window. Choose the
configuration you will use to run your Caliber SDK app and hit Edit. In the
VM parameters text box, enter something like this:

-Djava.library.path="C:\Program Files\Borland\CaliberRM SDK 6.5\lib"

Of course, the actual path will depend on where your jvb.dll file is.

You will need to do this for every application that might use a different
runtime configuration.

BTW, I didn't know how to set this in JBuilder until Lori told me the other
day.

Lori,

Count yourself surprised: I've never spotted anything in the Caliber SDK
that mentions how to fix this error or configure JBuilder to work with
Caliber. The ST manuals are much better in this regard.

Since the .dll's go with class libraries, it would be nice of JBuilder XI
let you set these things when you configure a library, rather than with each
configuration that uses the library.

You should make a RFE on Quality Central for this. It sounds useful.
There are more libraries out there than CaliberRM which have associated
DLL (or .so) components.

You need to add the following to your project property in the JBuilder runtime parameters:

-Djava.library.path="C:\Program Files\Borland\CaliberRM SDK 7\lib"

or wherever the jvb.dll resides on your machine.

HTH,

David
