Hi
The problem still exist after I manually deleted both
myproject/war/myproject and
myproject/war/WEB-INF/classes directories.
I have JDK 1.5 and JRE 1.5 and 1.6 installed on my Windows:
C:\Program Files\Java\jdk1.5.0_18 (JAVA_HOME)
C:\Program Files\Java\jre1.5.0_18
C:\Program Files\Java\jre6
I'm using JDK 1.5 for development, and jre1.5.0_18 is the only Installed JRE
configured in Eclipse.
The JRE 1.6 is merely used for Google Chrome.
Can I safely tell that all Eclipse, GWT and Jetty are running on Java 1.5?
