Hi. Building c3p0 should be as easy as editing build.properties and typing ant. Please send any feedback / questions to Steve Waldman All of the test related properties are very optional. There are various test tasks in the build file, but they are ad-hoc and unsupported. Someday I plan to get with jUnit and do real testing, but that day has not yet come. Until then, you, my dear user, are my primary testing engine. Sorry. Steve Waldman Machinery For Change, Inc.
