Chris, Thanks for offering to help. Since you've already got a
working Geronimo webapp that uses Dojo in GERONIMO-1823 I would love
to see how this idea holds up. How about moving the Dojo library from
your webapp into separate webapp available at the context root "/dojo"
and then adjusting your webapp to point at it? Depending on how you
referenced Dojo in your scripts and html you may have to include a
line like:
dojo.setModulePrefix("dojo", "/dojo");
after you load dojo.js. I also figured out a way to dynamically load
dojo.js from a javascript file (instead of html) if you that would
help.
To start the Dojo webapp and make its resources available you would
also need to add a line to your webapps geronimo-web.xml like
<dependencies>
<dependency>
<groupId>dojo</groupId>
<artifactId>dojo-toolkit</artifactId>
<type>war</type>
</dependency>
Does that sound reasonable? Feel free to take this idea and run with
it, get creative, etc :-)
Best wishes,
Paul

This is a good idea Paul. I'm not exactly sure how you
would implement it but let me know if I can help with
anything (testing, dev, docs, etc.). This will
definitely help those who wanted to develop Ajax
enabled apps in G. Also nice to have is if we can find
a way to do the same thing for DWR if it's possible.
Cheers,
chris
