Subject RE: Still problems to create Ant task
Date Mon, 16 Oct 2006 08:24:11 GMT

Hi Andrus.

I realized that it only works if I add the cayenne.jar to the $CLASSPATH
outside of ant. 

Other wise cayenne cannot find the adapter, but the ant task always
finds it. 

I have added a few lines to you example to instantiate the Adapter, and
they never fail. 

Object obj= null;
try{
	obj =
Class.forName("org.apache.cayenne.dba.oracle.OracleAdapter")
		.newInstance();
}catch(Exception e){
	throw new BuildException(e);
}


I send an example attached. 
I assume you have cayenne.jar in your classpath.  

If you run ant in the AntExample folder it should work (in your
environment should only complain about not been able to connect to the
DB) 

If you execute the ClearClasspath batch file (or just remove cayenne.jar
for your $CLASSPATH) and then run ant again, it would say that it cannot
find the adapter. 


Is it there any way to avoid it. I would rather been able to fully
configure the working environment from within ant. 

Thanks again for your help.

Cheers

Felipe

I just created a small test project and it seems to work just fine.  
The jar path includes cayenne.jar, task.jar and driver.jar.

Andrus

public class TestTask extends Task {

	protected File cayenneProject;

	public void setCayenneProject(File cayenneProject) {
		this.cayenneProject = cayenneProject;
	}

	public void execute() throws BuildException {
		Configuration c = new FileConfiguration(cayenneProject);
		Configuration.initializeSharedConfiguration(c);

		DataNode node = (DataNode)
c.getDomain().getDataNodes().iterator()
				.next();
		DataMap map = (DataMap)
c.getDomain().getDataMaps().iterator().next();

		DbGenerator gen = new DbGenerator(node.getAdapter(),
map);
		try {
			gen.runGenerator(node.getDataSource());
		} catch (Exception e) {
			throw new BuildException(e);
		}
	}
}


<project name="test" default="d">

	<path id="lib.path">
		<fileset dir="lib" includes="*.jar" />
	</path>

	<target name="d">
		<taskdef name="x" classname="test.TestTask"
classpathref="lib.path"/>
		<x cayenneProject="src/cayenne.xml"/>
	</target>
</project>
