## Java CLASSPATH environment variable

The Berkeley DB Java class files are now packaged as jar files. In the 4.0 release, the `CLASSPATH` environment variable must change to include at least the `db.jar` file. It can optionally include the `dbexamples.jar` file if you want to run the examples. For example, on UNIX:

    export CLASSPATH="/usr/local/BerkeleyDB.4.8/lib/db.jar: \
    /usr/local/BerkeleyDB.4.8/lib/dbexamples.jar"

For example, on Windows:

    set CLASSPATH="D:\db\build_windows\Release\db.jar;
    D:\db\build_windows\Release\dbexamples.jar"

For more information on Java configuration, see the Berkeley DB Installation and Build Guide. .
