Heiko-

Glad to hear it.  We'll look forward to your input on new features,
etc.

You can download both from the Unidata software downloads page:

http://my.unidata.ucar.edu/modules.php?name=Downloads

You'll need to set up an account first.

Unfortunately, our javadoc's are not complete either.  There is
a preliminary developer's guide in the /ucar/unidata/apps/example/docs
directory when you unpack the source. That might be a starting place.
In the next few months, we hope to improve the docs.  

The Javadoc is available online from the link on the IDV homepage:

Okay.  For a while, we had a mistake in our WebStart JNLP file that
was not loading Java 3D on Linux.  This is probably what happened
to set your default to 2D.

To do the same thing through WebStart:

1) save the JNLP file at 
http://www.unidata.ucar.edu/projects/metapps/webstart/IDV/idv.jnlp
to your own system.

2) Edit it and change the following:

       <application-desc main-class="ucar.unidata.idv.DefaultIdv"/>

to:

       <application-desc main-class="ucar.unidata.idv.DefaultIdv">
            <argument>-sitepath</argument>
            <argument>"your path here"</argument>
        </application>

where "your path here" would point to the sitepath directory
that you set up as per my previous e-mail.

Put this jnlp file on your web server, make a page with a link,
and it should "just work". ;-)

You'll have to configure your web server to handle the JNLP MIME type.
Each Web server has a specific way in which to add MIME types. For
example, for the Apache Web server you must add the following line to
the .mime.types configuration file:

 application/x-java-jnlp-file JNLP

Check the documentation for the specifics of your Web server.

I'm making good progress on the color bar and hope to have something
preliminary at least by January.
