Ah, I think you just need to add the directory containing the
test.class file to your classpath. Assuming it's in the current
directory:
java -cp tagsoup-1.1.3.jar:jdom.jar:jaxen-1.1.1.jar:js.jar:. test
For example, I did the following simple case:
[rhino] cat test.js
java.lang.System.out.println("hello, world");
[rhino] java -classpath js.jar org.mozilla.javascript.tools.jsc.Main
test.js
[rhino] java -classpath js.jar:. test
hello, world
--N
