Yep , documentation is not clear enough in all cases ..but
yes you will have to dowlonad torque-gen-3.1.zip in order to obtain the
torque peer classes generator.

You will define your database schema and generate corresponding java classes
and sql statements
inside torque-gen distribution
define your schema here:
        /torque-gen-3.1/schema/your-project-schema.xml
define your generation properties here:
        /torque-gen-3.1/build.properties
after running
        ant build-torque.xml
inside the folder
        /torque-gen-3.1/
you will have the generated files here:
        /torque-gen-3.1/src/java
        /torque-gen-3.1/src/sql

(create java project..eclipse/jbuilder/jdeveloper/or by hand:))
get java files from /torque-gen-3.1/src/java
also here you will have to aquire the jars from torque-3.1 (here it is)

to configure
torque.properties - your database props here...
log4j.properties - log4j props...

both files are provided with the torque-3.1 distribution
and somewhere in the code of your project you will have to invoke  (once -
per application)

Torque.init("the full path to the file torque.properties");

hope this helps ...

torque as an engine realizes the object2relational mapping by creating
(offline/design time) wrapper & peer classes for
each table in your database schema...that is why you first have to generate
those classes via torque-gen..

and these classes use torque engine (which is in torque-3.1.zip) that is why
you have to include torque engine jars to the project afterwards

torque-gen-3.1.zip (torque generator) is used before compile (design time)
torque-3.1.zip (torque engine) is used while compiling (and of course at
runtime :)

if there are other questions give them ..

with best regards,
bogdan

Hi, yes that's right I am talking about the torque-3.1.zip. If I've
understood you correctly that means we need to extract both the
torque-3.1.zip and torque-gen-3.1.zip archives before using the
application, right?

I don't think the tutorial guide emphasises this?.

Thanks.

Hi,
I am not sure ...but as i see in your post ..you are talking about the
torque-3.1 zip

this the torque engine ..and must be includeded (as a bunch of jars
inside your deployment infrastructure)

the folder like /schema, /templates are inside the torque-gen-3.1.zip

this is a separate zip file ..and contains the torque generator (inc
schema,templates, generation build file etc..)

Is that right that you talk about torque-3.1.zip (not
torque-gen-3.1.zip) ?


With best regards,
Bogdan

Subject: torque-3.1.zip archives


Hi,

We're investigating torque-3.1 as a strategic solution, but have noticed
that the .zip archive is missing a number of resources specifically the
/schema, /templates, build.properties and build-torque.xml directories
and files respectively.

1) Is there a reason for this since it cause confusion when using the
tutorial?.

2) We've tried the tutorial on v3.0 but class generation produces an
empty file report.bookstore.om.generation, can anyone help?

Apologise if these question have been answered before, but I can't seem
to access the mailing list archives.

Thanks.
