[udig-devel] Udig and webstart

[Johan C. de Koning]

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.

Bye

Johan de Koning
