Re: [udig-devel] Custom App Tutorial 
Thanks Ruben:

Since we have last spoke I put the docs into the public repository:
- http://svn.refractions.net/udig/docs/trunk/

I will see about updating the typo now.
As for the osgi.parentClassloader=ext I make a point of trying to cover it; especially at the end when talking about adding a "jre" to your custom app. 

I suspect I need to include a picture.

To Jody,
Thank you for your reply and sorry for the long time it has taken to get 
back to you. I will follow up on the other issues I had next week.
After following the custom app tutorial, I had a custom app that worked fine but did not load images. When checking the VM arguments, I saw that it was shorter than the arguments for the udig.product. Unfortunately I did not write down what the custom.product arguments were before I changed them (so 
I do not know if they included -Dosgi.parentClassloader=ext).

Since the udig.product application works with images, I used its VM
arguments for the custom app and everything worked fine. Once things worked 
I did not explore any further, and so do not know what
doNotLoadResourcesPlugin does.

Also note, I previously (11/23/2009,
http://lists.refractions.net/pipermail/udig-devel/2009-November/016520.html ) sent an email with some other errata in the custom app tutorial. I think most of those have been fixed (but did not take detailed notes on my last run through), but I still ran into the typo I described on page 19 in the 
most recent custom app tutorial.

Yeah questions - I am going to make an RC3 next week so
documentation changes / feedback is well timed.

Custom App tutorial (custom.product)
-------------------

My first attempt at this (using 1.2 RC2 on windows) produced an

application

that could not open images. It turned out I needed to change the Run
Configuration / Arguments / VM arguments to:

-Xmx386M -Dosgi.parentClassloader=ext

-Dorg.eclipse.emf.ecore.plugin.EcorePl

ugin.doNotLoadResourcesPlugin=true

This is the same as for udig.product. I haven't done any

further research as

to what the exact problem was (gdal libraries not being found

presumably),

I know about the -Dosgi.parentClassloader=ext one - we need that
so that geotools can see the JRE extensions (Java Advanced
Imaging and Java ImageIO). By default osgi is very protective and
does not allow access to JRE extensions!

I am not sure about the doNotLoadResourcesPlugin one? Where id
you find that?

Finally you should not have to change the arguments; it should be
defined as part of your custom "product" as per the workbook
instructions.

One of the bonus workbook instructions describes how you should
package a "jre" folder in your produced custom application (in
order to not be effected by whatever java your user has installer).

FInally we have move the Custom App Tutorial into the public svn:
- http://svn.refractions.net/udig/docs/trunk/devel/

Formally it was hiding with the commercial training materials in
a private repository for academics or people taking a course.
