[solved]Running JasperReport demo/samples/xmldatasource with Jython

[evaluat0r]

Hi! 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:

log4j:WARN No appenders could be found for logger (net.sf.jasperreports.extensions.ExtensionsEnvironment).

log4j:WARN Please initialize the log4j system properly.

Traceback (innermost last):

net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRRuntimeException: No query executer factory registered for the 'xPath' language.

 

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 how if using Jython?

 

thank you!

 

[evaluat0r]

Is it possible to register the xpath factory in this code?

[evaluat0r]

hi!

i found a way to solve this problem using PY4J instead of Jython.

cheerio!
