I purchased a license to JExpress, but whenever I try to build a project from the command line, or using a make tool such as Ant from Apache's Jakarta project, I get the message: Error: 5001: Your evaluation period has expired.

Set the working directory, or the JVM's initial directory, to the installation directory of JExpress.
Applies to
4.1 and earlier
unattended build, evaluation expired, make tools, Ant from Apache's Jakarta project
