Subject: Mac OS X: ImageIO causes crashes when loading
Java applets in Firefox, Camino, Opera - msg#00071
We have found that installing the Java extension JAI-ImageIO, used by
gvSIG, causes crashes when a Java applet is loaded in Firefox, Opera,
Camino and possibly other web browsers (but NOT Safari, Webkit and
those based on their same engine).
JAI-ImageIO is installed by gvSIG on OS X in its first run, in such a
way that it is available for the user running gvSIG; it does not
affect other users in the computer.
To uninstall JAI-ImageIO, one only needs to delete the file
"jai_imageio.jar" that can be found in: user's Home directory ->
Library -> Java -> Extensions.
The same thing can be done just by pasting this in a Terminal.app
window:
rm ~/Library/Java/jai_imageio.jar
We have found a way to avoid installing this file, so future gvSIG
versions won't install it and will offer to instead delete it.
To GeoTools users: there is a possibility that jai_imageio.jar is
needed by Geotools too, so deleting the file can cause GeoTools to
stop working. You'll have to ask them for suggestions.
For those wanting more details:
Since the advent of Safari, Apple has cared a lot more of supporting
Java in its web browser than in the rest. In fact, current browsers
that do not use Safari's engine (like Firefox, Camino and Opera) have
serious trouble adequately supporting Java, since the standard ways in
other platforms do not work in OS X.
So those browsers use the open source Java Embedding Plugin
(javaplugin.sourceforge.net), which handles the dirty work of
interacting with the Apple JVM.
JAI-ImageIO is not supported in OS X (in fact there is no distribution
for OS X). For gvSIG we have managed to get the basic functionality,
but, as seen, unexpected and difficult problems do pop up. In this
case, the Java Embedded Plugin crashes, and with it, the browser that
is using it.
Luckily, we have found a way to sidestep the problem: we'll use JAI-
ImageIO not as an extension, but included in the Classpath. That's
what we will do on future gvSIG versions.

gvSIG Mobile (pilot) released.
Hello everybody and sorry for the cross-posting.
It gives us great pleasure to announce that the pilot application
awarded the development contract for the gvSIG Mobile application by the
Regional Ministry of Infrastructure and Transport is available. gvSIG
Mobile is a smaller version of gvSIG which has been adapted for use in
mobile devices. It supports shapefiles, ECW, WMS and images and is able
to make use of GPS systems. Currently, only the visualization of layers
and the generation of GPS tracklogs/waypoints are supported. There is an
extension for gvSIG Desktop available too which allows cartographic
information to be exported from gvSIG Desktop to gvSIG Mobile.
Both gvSIG Mobile and the syncronization extension are available at
gvSIG website http://www.gvsig.gva.es
We hope it's really useful for you and don't hesitate to send us any
comment.
Kind regards.
The gvSIG team.

Some bugs
Hi all,
I'm new to this list and fairly new to the gvSIG program, although I
have been using it a lot over the past few weeks and I think it is a
really excellent program.
Although not of critical importance, I would like to contribute to
making gvSIG a better program by reporting the following bugs that I
have found in it (v1.1.2, WinXP). I hope someone could help me with these:
1. An inexplicable change in font size occurs when I move the text of a
selected annotation point. This happens in the annotation layer, and
occurred whilst I was editing a project containing nine SHP layers.
2. In the map editor, a change in the fill colour (xxxx pattern) of the
polygon rings from the Buffer GeoProcess occurs upon selecting 1:1 zoom
of the A3-sized map. The colour of the fill pattern changes from pink
(the colour it should be) to grey, and this re-occurs sporadically when
zooming to different levels.
3. Also in the map editor, the size and spatial layout of objects change
upon returning to the map window after having been in the view window.
However, upon clicking on 1:1 zoom, the objects return to normal. I am
guessing because this is a problem that can be remedied by essentially
'refreshing' the view, it is not too big a deal.
Many thanks for any help,
All the best,
Rory Hill.
