Calling a Java class containing a Scala call

Guys,

I have a test program which inturn calls a Java class and in this Java class, I call a Scala class (or object, whatever it means in Scala). When I try to run my Test class, I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: scala/ScalaObject

Initially I though it might be due to the SCALA_HOME not being set. But I have set it and still get to see this error. Any idea as to why this is not executing?

Ok. Got this to work. Added the scala-library.jar to the classpath in the java command line option.
