+= Maven, Torque and the torque:jdbc goal =
+If have spent some time trying to get maven to work with torque:jdbc and there seems to be
little doco on either (at least for a complete maven and torque novice). So here are the steps
I used to get it working with Microsoft SQLServer.
+ 1. Install an appropriate Java SDK 
+ 2. Add the Java SDK bin directory to your path variable so that you can type 'java' at the
command prompt and it successfully starts.
+ 3. Install Maven
+ 4. Add the Maven bin directory to your path variable so that you can type 'maven' at the
command prompt and it successfully starts.
+ 5. Use Maven to install the torque plugin as follows: (check the [Maven-howto for the latest
details on this|http://db.apache.org/torque/maven-howto.html])
+    maven plugin:download -DartifactId=maven-torque-plugin -DgroupId=torque -Dversion=3.1.1
+ 6. Create yourself a project directory (this can be anywhere you like).
+ 7. In your project directory create a project.properties file as follows:
+# -------------------------------------------------------------------
+#  T O R Q U E   S E T T I N G S
+# -------------------------------------------------------------------
+torque.project = MyDatabase
+torque.database = mssql
+torque.database.createUrl = jdbc:microsoft:sqlserver://localhost:1433
+torque.database.buildUrl = jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=MyDatabase
+torque.database.url = jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=MyDatabase
+torque.database.driver = com.microsoft.jdbc.sqlserver.SQLServerDriver
+torque.database.user = dbusername
+torque.database.password = dbpassword
+torque.database.host = localhost
+torque.database.schema = %
+'''Note''' the schema setting may be different for different database types as a hint the
following java call is made to return tables
+tableNames = conn.getMetaData().getTables(null, schema, "%", types);
+Where schema is taken from the torque.database.schema settings in the project.properties
+If when you get to the generation step and it appears to works but you have a schema.xml
file which contains no tables then its probably because the schema setting is wrong.
+ 8.#8 create a src directory under your project directory
+ 9. create a schema directory under the src directory you just created.
+ 9. Obtain the jars for your chosen databases' jdbc library. e.g. for SQL Server you need
msutil.jar, msbase.jar and mssqlserver.jar
+ 10. I had a real problem injecting these jars into the classpath, all of the normal techniques
don't work with maven. I have found some doc which says to add the jars to the torque project.xml
dependancies but I was unable to get this method to work and as soon as you update (re-install)
the torque plugin you loose your dependancies. So the hack I came up with is to copy the database
jdbc jars into the maven install. Under the maven installation directory (as of maven 1.0.2)
you will find a lib\endorsed directory. Just copy your database jars into there and all will
be well.
+ 11. run maven torque:jdbc at the command prompt making sure that your current working directory
is your project directory.
+ 12. You should seem something similar to :
+C:\dev\torque>maven torque:jdbc
+ __  __
+|  \/  |__ _Apache__ ___
+| |\/| / _` \ V / -_) ' \  ~ intelligent projects ~
+|_|  |_\__,_|\_/\___|_||_|  v. 1.0.2

+    [torque-jdbc-transform] Torque - JDBCToXMLSchema finished
+Total time: 16 seconds
+Finished at: Sat Feb 05 06:47:00 EST 2005
+ 13.#13 At the end of the above process you torque should have created a schema.xml under
your project directory src/schema/
+ 14. Check the schema.xml actually contains your databases tables. If not check the torque.database.schema
setting in your project.properties file.
+Hope this helps.
 a great hands on tutorial at http://users.volja.net/amanita1/
