How to change to syntheticaOrangeMetallic Look and Feel?

i want to change syntheticaBlueMoon to syntheticaOrangeMetallic from javasoft.

i did copy the syntheticaOrangeMetallic.jar to build/lib/dist , and import it in /spark/src/java/org/jivesoftware/ with " de.javasoft.plaf.synthetica.SyntheticaOrangeMetallicLookAndFeel". but after i built ant and startup it. the look and feel return error and use winxp look and feel instead.

how to solve this problem?

if cannot , how can i change look and feel from blueMoon to OrangeMetallic (or another look and feel)??


here is the error message when start spark

the problem is solve.

the look and feel of metaliclookandfeel error is because of the synthetica.jar version is outdated.

the latest version of synthetica.jar is 2.72
