Re: [udig-devel] Udig and webstart
|
Jody,
I was not possible for me to response earlier but in the mean time i
have webstart working.
The main problem is the two JRE extensions. These should be installed
inside the classpath of the JRE. We found a way to solve it to create
extra libs plugins (OS specific) which are holding the extension jar and
other birary files (like ddl). I don't know if this result in a
performance penalty because still the native versions are used. I also
don't know if i am allowed to provide the extensions this way because of
the license of these two extensions? Does somebody now if this is
allowed to do, the different files are still bundles together inside the
new plugins.
BTW the normal webstart versions of the both extensions are not working
because they are installed on a different location inside the javaws
cache and are this way not available for the udig plugins. Javaws cannot
install these extensions inside the JRE. So the solution described above
is for my opinion the best.
I will try to create a wiki page about how to get webstart running for
your custom application. Hope i can create this page soon.

My impression was that java web start could also install JAI and
ImageIO extentions; I have not looked at it for some time. Worst case
senario you could uses these projects in "pure jar" form without their
DLL files ... it would be slower but would run.
Questions;
- have you accounded for the osgi settings; ie when the application is
run does OSGi have access to the boot classpath?
- you say the jars are downloaded for the extentions - where do they
go? Are they installed into the JRE?
- Would you consider writing a wiki page on how to make (say the cusom
app tutorial) available as a webstart application?
Cheers,
Jody
Hello,
A customer wants to have the udig functionality available with
webstart. Getting udig running with webstart is not the problem if
you have a jre with the extension installed. But if you don't have
the advanced imaging and image i/o the map rendering functionality
does not work. Of both extensions a webstart version is available and
added both to my jnlp file. Starting webstart these files are
downloaded but udig is still not working properly. What to do next?
