HOBLink JWT 3.1 - Restrictions, Recommendations and Fixes

1. Restricted functionality

Clipboard-Sharing under Linux can cause problems for some JVM's. The Easy Print function, due to an error in the Apple JVM (MRJ) cannot be used on a MAC with OS 9 or older. HOBLink JWT is no longer supported for Mac OS 9 or older.

Requirements:
Java Virtual Machine version 1.1 or up (for some platforms, this can be installed with JWT 3.1)
64 MB RAM
150 MHz Pentium (or comparable processor from another manufacturer) or up.

Attention: If you have any trouble installing JWT 3.1 without a JVM (installation is interrupted, "Checksum Error in Release File"), please install JWT 3.1 with a JVM.

For the optimal operation of HOBLink JWT, we recommend the following Java Virtual Machines:

Platform

JVM (download current version)

Windows

Java 1.1.8 from SUN (http://java.sun.com/products/archive/j2se-eol.html )

Java 1.3 from SUN (http://java.sun.com/j2ee/1.3/download.html )
MS jview Version 5.00.3167 or up (http://www.microsoft.com/mscorp/java/ )

Linux/Unix

Java 1.3 form IBM ( )

NOT Java 1.3 from SUN

NOT Java 1.2 from Blackdown

Macintosh

MRJ 2.2.3 or up ( http://www.apple.com/java )

Alternative

Note regarding EasyPrint:

If you have problems with the Easy Print function, please install the current printer driver on the client before trying anything else.
Diskettes or CDs delivered with a printer often contain obsolescent drivers. Usually, up-to-date drivers a can be downloaded from the manufacturer's Website.

For OS/2, you can find the most printer drivers at IBM: http://service5.boulder.ibm.com/2bcprod.nsf

3. Windows Terminal Server

SP4 should be installed on Windows 2000 Terminal Servers.

The fixes are cumulative, i.e., you only have to install the latest one.
