Its not necessarily saying the method doesn't exist, it is saying it
doesn't exist with the arguments and/or argument TYPEs you are giving it.
Look at the types in the dump of the method you mentioned and try to
javacast() your values to match those types when passing them in.
example: opendesign(javacast('string',thisfile), javacast('int',0))
...assuming that it is actually expecting a simple string and int.
If that doesn't work, try posting the method dump or (if you have it) a
working.NET example of how it is used.
