Subject RE: newbie's questions help pls
Date Thu, 13 Nov 2003 18:25:30 GMT
Yeah I have a schema definition. And now when I run ant ant -f
build-torque.xml

I get the following exception:

I was following the instructions given in an article given on Torque site.

Come on guys, is there no place where someone can learn to use the Torque
3.1

All tutorials and even that article
(http://www.developer.com/java/article.php/10922_1457081_2) refers to
earlier versions of torque

Hi Cloves,
Thanks for your reply. Here's what is going on with me. I modified the
build.properties and ran the ant -f build-torque.xml and it did generate
some sql stuff but didn't generate any java classes. All I got in the
src/java folder is a file named "report.bookstore.om.generation"

I just copied the stuff for build.properties given in the examples on apache
and modified that to put my database information.

But I got no java classes and Ant console gives no errors.

Any ideas ?

Thanks

Vikas

Hi Vikas

I assume the recommended distribution of Torque is the 3.1 release. I've
downloaded both torque-3.1.zip and torque-gen-3.1.zip. The tutorial you
mentioned seems to be a bit outdated. Extract torque-gen-3.1.zip to a
folder, edit build.properties to point to your database and create the db
schema definition XML in the schema folder. Run 'ant -f build-torque.xml'
and your classes will be generated.
Then, extract torque-3.1.zip, and use the JARs on the /lib folder to run an
example using the classes you generated.

Subject: newbie's questions regarding tutorials


Hi Everybody,

This is my first hr into torque and I was trying to go thru the tutorials on
the website. I would appreciate a little guidance regarding the following:

1. At http://db.apache.org/torque/tutorial/step1.html they tell you to get a
distribution of torque. I need to know which version of torque is
recommended.

2. On the same page they say " After you have obtained your copy of the
Torque, you can either unpack the jar-----". I downloaded the torque-3.1.zip
and its lib directory it does have torque jar but no source in it. So do I
have to download the zip with the source and build it in my IDE and proceed
or what ? unjarring to get class files doesn't make much sense. So what do
those instructions imply when they say that unjar and obtain a specified
directory structure.

Maybe I'm asking some stupid question but I'm kinda confused how to proceed.

Please guide

Thanks

Vikas
