I have problems getting the xmldatasource sample project running with Jython.
This is my code:
#!/usr/bin/jython
"""
- cd buildEnv/xmldatasource; ant javac
- cd buildEnv/xmldatasource/build/classes; jar -cf xmldatasource.jar XmlDataSourceApp.class
- copy buildEnv/xmldatasource/build/classes/xmldatasource.jar to deploy/lib/xmldatasource.jar

import XmlDataSourceApp
from java import util
import java.io as javaio
properties = util.Properties()
propertiesfis =javaio.FileInputStream("jasperreports.properties")
properties.load(propertiesfis)
javaObj = XmlDataSourceApp()
javaObj.fill()
As you see, all the dependencies should be load. When i try to call the fill() method, i receive the following error:
l
og4j:WARN No appenders could be found for logger (net.sf.jasperreports.extensions.ExtensionsEnvironment).
log4j:WARN Please initialize the log4j system properly.

I run this code simply with jython java.py.
I think the code isnt work but I dont know how to set the properties correctly. According to the sample project, the property must be set as the following:
net.sf.jasperreports.xpath.executer.factory=net.sf.jasperreports.engine.util.xml.JaxenXPathExecuterFactory
But what if I use Jython?
I solved the problem of the java properties using PY4J instead of Jython.
