You could try pulling the classes out of the Ptolemy II 2.0-beta
release tree and using those, but I'm not sure if there is
a change that particularly addresses the issue you are having.
Below are the changes:
--start--
The changes between ptplot5.1p3 and ptplot5.2
* David French: added removeLegend()
* John Olmstead, Edward A. Lee: rotate Y axis label
* Christopher Hylands: Use .plt and .xml as default extensions when
opening or saving as, use plot.xml as a default name
* Roger Schwenke, Christopher Hylands: Add better documentation
about how to use Log axes.
* Alberto Gobbi, Christopher Hylands:
Fix for <dataset name= ... connected=...> to PlotMLParser.java
The changes between ptplot5.1p2 and ptplot5.1p3
* Ross Beyer: Problems with Solaris installation.
* Laurent Etur: Scale the printout to fit the page
--end--
We don't have a servlet set up locally, so I can't directly test your
set up. Alberto Gobbi contributed some servlet code, which we have
not tested, but you can find at
http://ptolemy.eecs.berkeley.edu/java/ptplot/ptolemy-plot-servlet.tar.gz

I don't know of anything else out there for servlets, but I'm sure
that there must be something.
