Right click on the .jar files. Save these files to the : c:\j2sdk1.4.1\jre\lib\ext directory* and the c:\program files\javasoft\jre\lib\ext director*. Make sure this directory* is in the classpath as well. Add the following lines to your autoexec.bat file in Windows or to your systems variables in NT. set classpath = %classpath%;c:\j2sdk1.4.1\jre\lib;c:\j2sdk1.4.1\jre\lib\ext;.; set path = %path%;c:\j2sdk1.4.1\bin; Note: *The actual path and name of the directories may differ depending on where you installed the software!! Also, if you installed forte as well, then the path would include a directory under forte before the sdk directory.
