Hello,
I am working on an application to use Torque to create XML schema from the
existing database and then generate the Java OM classes from this schema on
the fly. For this I don't want to use the Maven 2 build. Hence I referred to
your JUnit case TorqueOMMojoTest.java and tried something similar like this:
private void test() throws Exception {
TorqueJDBCTransformTask task = new TorqueJDBCTransformTask();
task.setDbDriver("com.mysql.jdbc.Driver");
task.setDbUrl("jdbc:mysql://127.0.0.1:3306/pump");
task.setDbUser("user");
task.setDbPassword("password");
task.setDbSchema("pump");
task.setSameJavaName(true);
task.setOutputFile("test.xml");
task.execute();
System.out.println();
//setupContainer();
MavenProjectBuilder builder = (MavenProjectBuilder)
lookup(MavenProjectBuilder.ROLE);
* ArtifactRepositoryLayout localRepositoryLayout
= (ArtifactRepositoryLayout) lookup(
ArtifactRepositoryLayout.ROLE,
"default");
*
ArtifactRepository localRepository
= new DefaultArtifactRepository(
"local",
"file://" + getBasedir() + File.separator
+ "target/test-classes/repository",
localRepositoryLayout);
MavenProject mavenProject = builder.buildWithDependencies(
new File(
getBasedir(),
"target/test-classes/projects/TestJDBCtoXMLTransformationTask/pom.xml"),
localRepository,
null);
OMMojo ommojo = new OMMojo();
ommojo.setContextPropertiesPath(mavenProject.getBuild().getDirectory()
+ "/torque/context.om.properties");
ommojo.setOutputDir(mavenProject.getBuild().getDirectory()
+ "/generated-sources/torque");
ommojo.setSchemaDir("");
ommojo.setUseClasspath(true);
ommojo.setBasePrefix("Base");
ommojo.setSubpackageMap("map");
ommojo.setTargetPackage("torque.test");
ommojo.setSchemaIncludes("test.xml");
ommojo.setSchemaExcludes("");
ommojo.setReportFile("om.generation");
ommojo.setBaseReportFile("om.base.generation");
ommojo.execute();
}
When I run the application I get the following exception:

I could generate the *test.xml* with the schema details of the existing
database.
I know the error is because it is not able to find the "default" artifact
repository layout. If anyone can provide information about how to solve this
issue then it would be of great help.
If you can suggest other alternative way of using the Torque to do the same
then it would be great.
Thank you,
Best Regards,
Amar
