PlotWS software

[Kim L. G. <kim...@gm...>]

Hi all,
  I've been using the open source PlotWS software.

http://www.soton.ac.uk/~ghydflex/plotws/ :

"PlotWS provides a graph generation WebService. It is implemented as a
wrapper around gnuplot and exposes a subset of gnuplot's
functionality. The Web Service layer is implemented using Apache AXIS."


Below, I like to share some steps I took to get the PlotWS software
working on my Red Hat 9.0 system. Hopefully, they could be of help to others.

1) Modify GraphSoapBindingImpl.java and change
exe.run(exeGnuPlot + " \"" + cmdsFile + "\"", _tempDir, null);
to
exe.run(exeGnuPlot + " " + cmdsFile, _tempDir, null);

2) After deploying PlotWS.war, make sure that the gnuplot executable
has execute permissions. e.g.:
chmod +x PlotWS/WEB-INF/exe/gnuplot

Perhaps, PlotWS could be added to the links page,
http://www.gnuplot.info/links.html under Java (where it says " Version
for Java and others: please contribute.")
