Documentation says that
quote:
*Requires that your target system has the Java 1.4 or 5.0

When I try to compile under 1.4 I get an error
quote:
class file has wrong version 49.0, should be 48.0
which implies that the required version is 1.5 - is this correct?

The qcchart2djava and qcrtgraphjava libraries themselves are compatible with Java 1.4. Most all of the example program for the QCRTGraph utilize parametrized collections (Vector), because the use of un-parametrized collections now generates hundreds of warnings in current versions (last 3-4 years) of Eclipse. Parametrized collections are only supported under Java 1.5 and higher. The QCChart2D examples don't use collections and they should all compile and run OK.

Is this just an observation, or is there some reason you need to restrict yourself to Java 1.4?
