I have been successfully using JDK 1.3 and JRE 1.3 with WSAD 5.1.2. Now I have to add few jar files which are built with JDK 1.4 and including them in my project throws errors like "missing type org.ietf.jgss.GSSManager" . I did install J2SDK 1.4 on my machine but how do I force WSAD to build my project using J2SDK 1.4.
I tried following options 1. set up new JRE directory in Window -> Prefernces -> installed JREs. and selected it. 2. Go to Window -> Prefernces -> Compiler and set following values : Compiler complice level - 1.4 Generated .Class file compatibility - 1.3 source compatibility 1.3 ( Note: new files are jar files and not the source , so I kept it 1.3 in this setting) 3. Go to project properties and repeat step# 2
