java.lang.NoClassDefFoundError: sun/swing/plaf/synth/SynthUI

Question

I am using Seaglass Look and Feel for my Java Swings code. But I keep getting this error.

    Exception in thread \"main\" java.lang.NoClassDefFoundError: s         


        

Answer 1

The best way to test the compatibility is to check whether the code is working with Java 6 (If you are using any IDE like eclipse of Intellij they have the option of compiling file with lower Java version).

From the error it seems that at run-time it is not able to find the Class, or the path where it is located. You can try java -cp to specify the path.
