I solved this problem using PY4J.

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

I have tried this: net.sf.jasperreports.engine.util.JRProperties.setProperty("net.sf.jasperreports.xpath.executer.factory", "net.sf.jasperreports.engine.util.xml.XalanXPathExecuterFactory"); but i still receive the following error: net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRRuntimeException: No query executer factory registered for the 'xPath' language.

hi! I know that normaly the setting about the xpath factory is configured by the jasperreports.properties file. but is there also a way to set the xpath factory in the code? The setting (or better the property) is: net.sf.jasperreports.xpath.executer.factory=net.sf.jasperreports.engine.util.xml.JaxenXPathExecuterFactory

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

Hi! I have problems getting the xmldatasource sample project running with Jython.

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!

Hi Lucian A perfect answer. Thank you! ps. this thread can be considered as [solved].

Hi! Im evaluating a suitable report engine for my project. The JasperReport library looks promizing. I've read that it is possible to feed the data from different data sources and to set "some" data via parameter. In my case I'd like to prevent the report library to access the database directly. I have a centralised business layer. The report engine gets "executed" from this layer. I also would like to feed the data from the business layer. So is it possible to bring all data to the JasperReport library as parameters? thank you!
