Patch to make Velocity work on JDK 1.1

[Andy Carlson <an...@hotmail.com>]

Hi all,

A few months back I was working on a project which was constrained to use 
JDK 1.1 due to support issues with a legacy access library. I wanted to use 
Velocity but found that it required the JDK 1.2 collections (hmm... shouldnt 
these prerequisites be documented? - I digress)

After unsuccessfully looking for suitable alternatives, I decided to patch 
Velocity to work on JDK 1.1 using the Sun Infobus collections library. I've 
just dug my patch out again and updated it to Velocity 1.2 RC3. The result 
is attached in a zip file. It would be nice if this patch could be made 
available on the Velocity site.

The zip file includes a 'howto' document which should explain most things 
about the patch.

The following parts of Velocity are NOT supported:-
- JarResourceLoader
- Anakia
- Texen
- Use of the Avalon logging package (i.e. you must use Log4J)
- the ClassLoader change test (but this might be fixable)

The Velocity library patching is done entirely using ANT, so you can see 
exactly what is being done by inspecting build.xml.

The changes needed to the unit tests are somewhat beyond the capabilities of 
ANT's <replace> task, so extra files need to be unpacked over the Velocity 
originals if you want to run the test suite.

Some of the patches could probably be merged back into the main sources 
without causing problems.

I'm not sure if this list allows attachments, but I suspect I'm about to 
find out.

Regards,
Andy

Got the attachment :)

Will take a look _ I think that for the first go, this is something for the
contrib section of the site.  I assume that you will just have to chase the
releases and update if need be?

And I think it states in the README.txt that Java 2 is required.

jakarta-velocity/README.txt

REQUIREMENTS
------------
The Java 2 SDK is required to build Velocity.

That should probably be modified to say "build/run", but I think that the
intent of JDK1.2 is pretty clear. :-)

Oh yea, it also says it here in the first sentence:

<http://jakarta.apache.org/velocity/install.html>

Velocity runs on a variety of platforms that have installed the Java 2
Virtual Machine. The J2SDK is required for users who want to compile
Velocity from its source code.
