help with torque generator
Hi everybody,
I'm currently working on a large application project that will extend
one existing system that uses OJB. One of our main problems now is that
we can't use the xdoclet plugin anymore on the classes. We now have to
use a secondary XML file that is somewhat similar to the
project_schema.xml file.
As I don't have that much experience with Torque, I would like to add a
few questions.
>From the torque.jar file, it's possible to see that the generator uses
vm files to create the external documents. What exact format are those
vm files in? Is there any documentation on how I can extend, or create a
new vm file?
Is there anyway to have those vm files outside the torque package? I
tried copying some of the files to my project, so that I can then change
them, and I changed the torque-build.xml file, but I couldn't get it to
work (Resource not found - control.vm file).
Thanks a lot, guys!
I know this is not the dev list, but probably the developers check this
list, so congratulations to all you, for the great project!

I already modified those terrific vm templates to generate PHP-OO code.
Bogdan have pushed up a torque-app looking like Phpmyadmin and others
but on top of Torque and on the basis of your tables.
I think a repository for Torque and Velocity template would be a nice
project...
you can find some code sample and an IDE for extending Torque's
templates at http://www.devaki.org/nextobjects/

They are Velocity files (http://jakarta.apache.org/velocity)
Yes, you can add more vm templates to your project.
What makes life easier when editing the Velocity/Java jumble: I use an
editor (on the PC) called UltraEdit, for which I have a code colouring
for Velocity files.

Yes, I've done it. You have to change the torque-build.xml. You also
have to understand how the Torque people used Control.vm: this is the
template from which the generation of the actual code is controlled.
Control.vm, as it is, expects the other vm files to be in the same
directory.
The other thing you have to be aware of is that the schema.xml file is
expected in a certain location (generator\schema); in my Ant build I
copy my schema file from the project directory to this Torque directory.
You could also make the Torque generator directory tree part of your
project.
I am generating a whole lot of additional code based on the schema file.
I found it was really worth my while understanding the Velocity templates.

Yes, this is possible. The .vm files are _in_ the torque-gen.jar. If
you want to change or expand these, best would be to get the torque
source (the files are in src/generator/src/templates/) and rebuilt the
jar.

It should be possible. There are settings for the ant-tasks to load
the templates from a directory and not from the classpath. Sorry,
can't recall on the spot which these are.
