First of all, all Java solutions under OS/2 are using IBM's Java Runtime. You have to download and install it separately. The installation is only possible with an installed Navigator + Feature Installer! So get this parts first!
All these applications are available at Software Choice.
Sun's HotJava browser uses also IBM's Java Runtime, so you have to get and
install IBM's runtime first!
This configuration is working very well, but it is a very tricky installation!
