java.lang.UnsatisfiedLinkError

Exception in thread "main" java.lang.UnsatisfiedLinkError: no cb in java.library.path

This exception occurs when creating a new Code4jni object with CodeBase for the Java Programming Language. The exception occurs because the CodeBase native library (DLL on Windows) cannot be found. On UNIX and other systems, it can also be caused by a version difference between the run-time libraries on the system and the run-time libraries associated with with pre-built CodeBase native libraries. In addition, the -Xbootclasspath option will cause this.

Solution (Windows)

Locate the DLL32 folder. This folder should contain one or more DLLs. Each of these DLLs represents an index file format (FoxPro, dBASE, Clipper). Select the DLL that corresponds to your preferred index format. Rename that DLL to cb.dll and place it in your the library path. To determine your library path, you can run this piece of code:

class getLibraryPath
{
   public static void main(String[] args)
   {
      String path = System.getProperty("java.library.path");
      System.out.println(path);
   }
}

Solution (UNIX and other platforms)

Locate the libcb directory. This directory should contain one or more shared libaries. Each of these shared libraries represents an index file format (FoxPro, dBASE, Clipper). Select the shared library that corresponds to your preferred index format. Rename that shared library to libcb.so (or libcb.sl on some UNIX systems, and cb on Macintosh) and place it in the library path. To determine your library path, you can run the above piece of code.

If the first solution does not resolve the exception error, you may need to rebuild the CodeBase native library. Platform-specific instructions on building the shared native library are included in the documentation installed with CodeBase for the Java Programming Language. After you have rebuilt the library, place it in the library path according to the directions in the previous paragraph.

Solution (using -Xbootclasspath)

Set the property sun.boot.library.path so that it includes the directory where the CodeBase native library is. For example, if the native library cb.dll is located in your C:\WINNT\SYSTEM32 directory, then you would run Java with the -D option to set the sun.boot.library.path property to that directory:

   java -Dsun.boot.library.path=c:\winnt\system32 ...
