Thanks for the catch, Bernhard. Committed to the Beta4.0 branch in
r4928. Upcoming to trunk.

The tests are certainly one location. The intent is that:

  http://trac.openmicroscopy.org.uk/omero/wiki/OmeroClients

should be the starting point for anyone wanting to write an OMERO
client. It's a lot, though, and so any suggestions are welcome.

>From that page, several examples from:

  http://trac.openmicroscopy.org.uk/omero/browser/trunk/examples

are linked. The least of which are in C++. However, once you get a
feeling for one language, they are all nearly identical, so comparing
between Java, Python, and C++ will probably also help.

And of course, always feel free to ask. If the mailing list isn't
conducive to the type of help you need, you might either create a wiki
page where we can gather examples, or you can start a thread on the
forums: http://openmicroscopy.org./community

Cheers,

P.S. note the slice documentation at:

  http://hudson.openmicroscopy.org.uk/job/OMERO/javadoc/slice2html/omero.html

is undergoing improvement. Comments welcome.
