-== Installing release 3.1 ==
-
-Note that the tutorial is in serious need of updating.  It is based on Torque 3.0 which did
not include the separated runtime and generation components nor the Torque maven plugin. 
See TutorialErrata for details.
-
- * Basic install of torque and testing of example included in the tutorial 
-
-   * Download torque-3.1.zip and torque-gen-3.1.zip
-
-Extract the zips, you will now have <your_installation_path>/torque-3.1 folder and
<your_installation_path>/torque-gen-3.1 folder
-
-   * Merge the  folders and files from one folder into another (so you now have everything
under one folder)
-
-Edit build.properties (3 changes primarily -- torque.project ,  torque.database and the database
connection related setting.)
-
-   * Create a project-schema.xml file under <your_installation_path>/schema folder
(you can copy the example given in the tutorials)
-
-   * From the <your_installation_path> execute ant as follows
-{{{
-     ant -f build-torque.xml
-     ant -f build-torque.xml create-db
-     ant -f build-torque.xml id-table-init-sql
-     ant -f build-torque.xml insert-sql
-}}}
-
-
-   * At the completion of the above steps you might notice the id-table is not populated
even if the sql is executed.  Work around for this problem is to update your build-torque.ml
file as follows
-
-{{{
-Add the line 
-<replace file="${torque.sql.dir}/sqldb.map" token="id-table-schema.sql=@DATABASE_DEFAULT@"
value="id-table-schema.sql=${database.name}" />
-after the target tag "insert-sql" and before the target tag <torque-sql-exec ..../>

-A follow-up to Stuart's note (hmmm, maybe time-stamps would be useful? It's hard to know
how long ago people left this info.)[[BR]]
-I  was also trying to extract the schema.xml file from an existing database, and kept getting
a file that had no table/column information in it.  I found [http://www.mail-archive.com/torque-user@db.apache.org/msg02396.html
this post] describing my problem; it turns out at least for postgresql 7.3.4 (which I'm using)
you need the schema name to be set, so adding ''torque.database.schema = public'' was the
missing link.  Contrary to the docs, it's not just for Oracle and it doesn't have to be upper-case.

- 1#2. My problem turned out to be fairly simple to fix.  When I was browsing the site I didn't
find any references to what column types were allowed.  I mistakenly put LONG and BOOLEAN
in.  This causes the build to fail without any information on what went wrong or where.  After
I changed my types to BIGINT and BIT everything worked correctly.  Below I am including the
available types that I have found.

-From the dtd, your list is right, except you missed BOOLEANINT and BOOLEANCHAR. Since I haven't
test these types yet, I just report they are perfectly acceptable types from the DTD.

 This is somewhat related to the problem encountered by Pete. Received a 'generator.parse'
error using the default target from Ant.
 
 The problem turned out to be from a datatype in the source Oracle schema. Used the torque
'jdbc' task and the resulting xxx-schema.xml file had an empty type attribute for any columns
which were defined as Timestamps in the source Oracle schema. Modified the original ddl to
change all Oracle 'Timestamp' columns over to the type 'Date'. Once I rebuilt the schema in
Oracle, re-ran the torque jdbc task, torque's default (main) task worked fine.

 = Installing from CVS =
 
-I did go through the following steps to build torque from CVS
-
- 1. Download Torque from CVS. See http://db.apache.org/torque/cvs-usage.html for instructions.
+See: [http://db.apache.org/torque-31/developer-guide.html#Building Building]
 
- 2. Download and install maven (http://maven.apache.org/start/download.html). I used maven
1.0-rc3 on Windows. Don't forget to set the environment variable MAVEN_HOME to the appropriate
directory and to add the maven binary directory to the environment variable PATH.
+Some further hints:
 
- 3. Build torque: Run "maven jar" from the torque root diretory. Maven now downloads some
jar files. In the end, it complains about not being able to download jdbc-2.0.jar and jndi-1.2.1.jar.
As far as I know, jdbc 2.0 is contained in J2SE 1.4 and should therefore not be needed separately
if J2SE1.4.x is used, so I commented the jdbc dependency in project.xml in torque's root directory.
Another solution would probably be to download thew jdbc-2.0 optional package from http://java.sun.com/products/jdbc/download.html,
but I did not try it. Then download jndi-1_2_1.zip from http://java.sun.com/products/jndi/downloads/index.html,
unpack it, copy the file lib/jndi.jar into the directory .maven/repository/jndi/jars in your
home diretory and rename it to jndi-1.2.1.jar. Then run "maven jar" again. This will download
some more jar files, and build the library torque/torque-3.2-dev.jar. To generate the documentation,
run "maven site:generate". The documentation will be generated in target/docs.
+ 1. When you install Maven, don't forget to set the environment variable MAVEN_HOME to the
appropriate directory and to add the maven binary directory to the environment variable PATH.
 
- 4. Build the Torque Generator: change into the directory src/generator and run "maven jar".
It will download some jar files and build the library src/generator/target/torque-gen-3.2-dev.jar.
Again, the documentation will be generated by running "maven site:generate". The documentation
for the generator will be generated in src/generator/target/docs.
+ 2. If/when Maven complains about not being able to download jdbc-2.0.jar and jndi-1.2.1.jar
you will need to download these manually and install them in your local Maven repository.
jndi-1_2_1.zip is available from http://java.sun.com/products/jndi/downloads/ - copy the file
lib/jndi.jar into the directory .maven/repository/jndi/jars in your home diretory and rename
it to jndi-1.2.1.jar.  Do same for other jars.
 
- 5. Build the Maven plugin(see also http://db.apache.org/torque/maven-howto.html): change
into the directory src/generator and run "maven plugin:install". Maven complains about not
being able to download torque-gen-3.2-dev.jar. But as this file was already created, it can
be copied from src/generator/target/torque-gen-3.2-dev.jar to the .maven/repository/torque/jars
in the home directory of the user. Running "maven plugin:install" again seemed to create the
plugin.
