Setting a custom classpath in the Servoy Client

Hi,
I need to set a custom classpath on the Servoy Client side because I use some classes that aren’t in the default classpath (but are there on all Mac OS X systems).

I saw that in Servoy Client the value of the system property “java.class.path” is:

/Applications/Utilities/Java/J2SE 5.0/Java Cache Viewer.app/Contents/MacOS/lib/deploy.jar:/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Classes/.compatibility/14compatibility.jar

Who know how that classpath is composed?
I found this entry in the Java Cache Viewer’s Info.plist file, but it doesn’t perfectly match:

		<key>VMOptions</key>
		<array>
			<string>-Xbootclasspath/a:/Applications/Utilities/Java/J2SE 5.0/Java Cache Viewer.app/Contents/MacOS/lib/javaws.jar:/Applications/Utilities/Java/J2SE 5.0/Java Cache Viewer.app/Contents/MacOS/lib/deploy.jar</string>
		</array>

Is there another way to access classes outside the classpath?
TIA,
