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 files. +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 + +build:start: + +torque:init: + +torque:jdbc: + [torque-jdbc-transform] Torque - JDBCToXMLSchema starting + [torque-jdbc-transform] Your DB settings are: + [torque-jdbc-transform] driver : com.microsoft.jdbc.sqlserver.SQLServerDriver + [torque-jdbc-transform] URL : jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=MyDatabase + [torque-jdbc-transform] user : dbusername + [torque-jdbc-transform] schema : % + [torque-jdbc-transform] DB driver sucessfuly instantiated + [torque-jdbc-transform] DB connection established + [torque-jdbc-transform] Getting table list... + [torque-jdbc-transform] Building column/table map... + [torque-jdbc-transform] Processing table: dtproperties + +... you should see each table and view in your database listed here ... + + [torque-jdbc-transform] Processing table: tblAccount + [torque-jdbc-transform] Processing table: tblAllocation + [torque-jdbc-transform] Processing table: vwWatchList + [torque-jdbc-transform] C:\dev\torque/src/schema/schema.xml + [torque-jdbc-transform] Torque - JDBCToXMLSchema finished +BUILD SUCCESSFUL +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.
