I've been receiving an error when I try to access a Java
object, more specifically a constant in a Java object. What's
frustrating is that this error occurs on one ColdFusion server but
not on another. As far as I can tell there is no major difference
between these two CF servers. The constant in question is an object
itself, though this doesn't matter as calling a method in the
object yields the same result.
What I'm hoping to get from this forum is some idea of why
this error might be occurring. That is, what the error means. The
exception.log message has me baffled, but perhaps other people have
dealt with a similar error. Below is the stack trace (with some
pieces of data removed for security's sake). Note that the
NoClassDefFoundError cannot be referring to my Java object, as the
constant I'm referring to is quite clearly there. Also note that
the Java object has a unique name and wouldn't be confused with
another class on the server (I've tried changing its name, but
still got the same result).
