How to register a QueryExecuterFactory in jasper reports in java

Question

Hi,

I implemented JRQueryExecuter and want to use it in a report. Using iReport I managed to register and use the executer.

Now I want to use it in a java application, but I can't find any resources how to register the factory.

I thought it's enough to have the implementation in the classpath, but I get the following exception:

Caused by: net.sf.jasperreports.engine.JRException: No query executer factory class registered for tmql queries.
at net.sf.jasperreports.engine.query.DefaultQueryExecuterFactoryBundle.getQueryExecuterFactory(DefaultQueryExecuterFactoryBundle.java:80)
at net.sf.jasperreports.engine.util.JRQueryExecuterUtils.getQueryExecuterFactory(JRQueryExecuterUtils.java:57)
at net.sf.jasperreports.engine.design.JRDesignDataset.queryLanguageChanged(JRDesignDataset.java:1006)

Can anybody give me a hint?

regards Hannes

The documentation suggests to set a property:

JasperReport jasperReport = <...>
jasperReport.setProperty(JRQueryExecuterFactory.QUERY_EXECUTER_FACTORY_PREFIX + "<query language>", "<value>");

Does that work?
