Good. that's exactly what I wanted - JSR 168 out of curiosity, what exactly do you mean by "Its not J2EE 1.4 compatible"? Do you say that because it's using EJB3 which is becoming J2EE 5 compatible? Thanks PS when I ran the jems installer with jdk1.5 I saw an error like this: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.text.html.CSS$FontSize.getValue(CSS.java:1672) Jdk1.4 worked fine.
