I thought I'd have a nice surprise and release the new widgets and a PDF viewer...

But I just learned the hard way that PBP-1.0 doesn't just mean AWT with all the widgets torn out. Some of the supplied classes have been gutted of methods as well.

java.awt.Shape for example is but a pale shadow of the full AWT version.. The PDF Viewer was kind of expecting to have a full Graphics2D environment to implement Postscript upon.

You can get the PBP-1.0 Java Doc here: http://javashoplm.sun.com/ECom/docs/...actionId=noreg

Another gotcha for you other java developers out there: java.io.File's createTempFile/createNewFile. The System.getProperty("java.io.tmpdir") is set to a non-functional value. But even after dealing with that I was getting no love at all from createNewFile. I had to do my own file creation calls via new File("name of temp file") and feed that to an OutputStream constructor to get a file I could write to.

I also discovered that Runtime.getRuntime().totalMemory() and Runtime.getRuntime().freeMemory() return roughly 128MB of memory. Looks like something else iRex needs to tweak.
