[Db-torque Wiki] Update of "UsingAntForV311" by bdc34
Dear Wiki user,
You have subscribed to a wiki page or wiki category on "Db-torque Wiki" for change notification.
The following page has been changed by bdc34:
http://wiki.apache.org/db-torque/UsingAntForV311
New page:
= Using Ant to build Torque v3.1.1 =
== Justification and Goals ==
bdc34: I am unfamiliar with Maven but I wanted to use Torque to build
java objects for an existing MySQL db schema. After attempting
to use maven, and failing, I used ant and configuration files
from torque 3.1 to build torque 3.1.1. This is not a suggested procedure and you should
us maven if you can.
The first step was configuring Torque 3.1.1 to use ant.
Next the schema.xml needed to be generated using the ant target jdbc.
Then the java objects could be built.
This was done an an winxp box with cygwin.
== java and ant ==
I had nothing in jre/lib/ext. When I started there was something in that dir tha confused ant. I used jdk1.4.2 and ant 1.6.1.
== downloading torque ==
download torque-gen.3.1.1.zip and unzip to dir $TORQ3_1_1
download torque-gen.3.1.zip and unzip to dir $TORQ3_1
== Copy 3.1 config files to 3.1.1 ==
We need the v3.1 config files from $TORQ3_1 in the $TORQ3_1_1 directory.
These include:{{{
$TORQ3_1/build-torque.xml
$TORQ3_1/build.properties
$TORQ3_1/commons-logging.properties
$TORQ3_1/default.properties
$TORQ3_1/simplelog.propertes}}}
== Edit build-torque.xml ==
The class path of the $TORQ3_1/build-torque.xml, which was just
copied to $TORQ3_1_1/build-torque.xml needs to
be corrected to use jars in $TORQ3_1_1/

== Set build.properties ==
I used this:{{{
# The name of the project Torque will generate code for.
torque.project = vitro
# The target database platform.
torque.database = mysql
# The target package to put the generated classes in.
torque.targetPackage = edu.cornell.mannlib.vitro
# The JDBC URL that Torque can use to create db's
torque.database.createUrl = jdbc:mysql://localhost/junkCreateURL
# The JDBC URL that will be used to create tables in your database.
torque.database.buildUrl = jdbc:mysql://localhost/junkBuildURL
# The JDBC URL that will be used to access your database.
torque.database.url = jdbc:mysql://localhost/vivo3
# The JDBC database driver to use when connecting to your database.
torque.database.driver = org.gjt.mm.mysql.Driver
# The administrative username that has sufficient privileges to create
# and drop databases and tables that Torque executes at generation time.
torque.database.user =XXXyourUserXXX
# The administrative password for the supplied username.
torque.database.password =XXXyoupasswdXXX
# The hostname or IP address of your database server.
torque.database.host =localhost
# The location of the your *-schema.xml files (see below).
#torque.schema.dir = ./schema}}}
= Preparing the build dir =
== unpack the velocity templates from v3.1.1 ==
The Maven based v3.1.1 build pulls the velocity templates out
of the torque-gen.3.1.1.jar but the v3.1 build-torque.xml looks for them in
directories. We need to unpack the v3.1.1 jar and copy the
velocity template directories to $TORQ3_1_1/templates
unzip torque-gen.3.1.1.jar and move ./bla/bla/*.vm dir tree
to ./templates/bla/bla/*.vm
There may be a way to set build.properties so that the jar's
templates get used but I didn't look too hard for it.
== get the jar files for $TORQ3_1_1/ ==
The v3.1.1 zip comes with many jars that you need but here is the list I
ended up using. I had to add the ant.jar (ant v1.6.1). Also you need
to add a jdbc driver such as mysql-connector-java-3.0.16-ga-bin.jar.
This is what I had in my $TORQ3_1_1/lib:
{{{

= Running torque =
I was interested in generating a schema.xml from an existing database and
then generating java object to access that.
These ant commands should be run from the $TORQ3_1_1 directory
== Run the ant target to build the schema.xml form an existing db. ==
Run the command:
{{{ant -f build-torque.xml jdbc}}}
This will generate $TORQ3_1_1/schema/schema.xml
== Making the java objects ==
Torque expects to find your schema file at
$TORQ3_1_1/schema/${torque.project}-schema.xml but it puts the
schema that it generates at $TORQ3_1_1/schema/schema.xml
Move $TORQ3_1_1/schema/schema.xml to $TORQ3_1_1/schema/vitro-schema.xml
== Build the java db access objects ==
Run the command:
{{{ant -f build-torque.xml torque}}}
See the results:
{{{find . -name "*.java"}}}
= Final Notes =
These instructions have not been tested. I just took notes as I foolishly stumbled around and finally got this to work. Please add comments and corrections.
