Peter,
Many thanks for your help, here are my findings:
In your first example you suggested:
<script language="jython">
import org.apache.tools.ant.taskdefs.Mkdir as Mkdir
import java.io.File as File
testDir=File('./build/weblogic92/test')
mkdir = Mkdir()
mkdir.setDir(testDir) <-- Upto here it works
mkdir.execute()
</script>
A call to execute leads to a NullPointerException
Your second suggestion works!
<script language="jython">
import org.apache.tools.ant.taskdefs.Mkdir as Mkdir
import java.io.File as File
mkdir = project.createTask("mkdir")
mkdir.dir = File("createme")
mkdir.execute()
</script>
This code can also be run using my preferred form of calling an external
.py script:
<script language="jython" src="tools/jython/antCallTest2.py"/>
antCallTest2.py
import org.apache.tools.ant.taskdefs.Mkdir as Mkdir
import java.io.File as File
mkdir = project.createTask("mkdir")
mkdir.dir = File("createme")
mkdir.execute()
Thanks again, you have streamlined my weblogic build process greatly :)
Cheers,
Hoos

I normally use project.createTask() even though it does not support
presets.
example:
<project name="j">
<macrodef name="x">
<attribute name="y"/>
<sequential>
<echo>y is @{y}</echo>
</sequential>
</macrodef>
<script language="jython">
import java.io.File as File
d = project.createTask("delete")
d.dir = File("createme")
d.quiet = 1
d.execute()
mkdir = project.createTask("mkdir")
mkdir.dir = File("createme")
mkdir.execute()
</script>
<script language="jython">
x = project.createTask("x")
x.setDynamicAttribute("y", "abc")
x.execute()
</script>
</project>
outputs:
Buildfile: jython.xml
[delete] Deleting directory C:\work\a\createme
[mkdir] Created dir: C:\work\a\createme
[echo] y is abc
BUILD SUCCESSFUL
Total time: 1 second
