using maven 1.0.2 : 1. get the maven torque plugin 3.2 2. call the goal torque:jdbc with the correct properties see http://db.apache.org/torque/releases/torque-3.2/generator/properties-reference.html 3. call the goal torque:om with the correct properties.
you can find some documentation at http://db.apache.org/torque/releases/torque-3.2/maven-plugin/index.html and http://db.apache.org/torque/releases/torque-3.2/generator/properties-reference.html Ragards Raphaël 2006/2/8, Liu, Richard <[EMAIL PROTECTED]>: > > Hi, Dave: > > Thanks a lot for your answer. > > In your answer, you said that "Torque can reverse-engineer a database > and create the corresponding schema file, from which it can then > generate the Java source code necessary to use the database within a > Java program." > > > Do you have a step guide in terms of how could I really do what you > said above? or please tell me where can I find an example of the above > ? > > > > Thanks > > > Richard Liu > > > > > -----Original Message----- > From: Dave Newton [mailto:[EMAIL PROTECTED] > Sent: Tuesday, February 07, 2006 5:37 PM > To: Apache Torque Users List > Subject: Re: A few general questions of Torque 3.2 > > Liu, Richard wrote: > > > Am I right? > > Short answer: no. > > > 1) Given an XML Schema in an XSD file (or DTD > > file), generate a database schema that represents the XML Schema > > defined in the XSD > > > The schema is defined in an XML file. > > XSD and DTD are ways of defining what a valid XML file looks like. > > 2) Generate source code that can parse XML > > documents and insert (update and delete) the data into the generated > > database schema > > > No; Torque takes the schema as defined in an XML file and creates > classes that map data in the database to Java objects. > > 1) Generate source code that can extract data > > stored in the database schema and create an XML file that conforms to > > the XML schema defined in the XSD > > > I'm not even sure what you mean by this; to me it sounds like the same > thing in #3 belo > > 2) Generate queries to extract data from the > > database and create an XML document that conforms to the XML Schema > > defined in the XSD file > > > Briefly: Torque uses an XML file to define database tables and the > relationships between them.
