I believe currently you can only apply rules on POJO, you could use JAXB to convert from
XML to POJO but this doesn't work very well on deeply nested or complex data
structures if you wish to perform updates on the data.
XML support is something I've been pondering over as to how easy it would be to do. If
I get some free time I might put together a prototype to see how well it would work as
currently the application I'm working on does the JAXB route and it isn't great,
particular with respects to updating different fields and re-execution of rules.

Hi All,
Can you please let me know if I can apply rules on xml data using Drools or we can just
apply rules on POJO.

RE: [rules-users] Drools Guvnor installation on weblogic
________________________________
The datasource defined in the persistence unit (jta-data-source or non-jta-data-source) of
the persistence.xml maps to the JNDI name that must be configured beforehand. In your case
you need to have the datasource configured against the jdbc/testDS1 jndi name.

Vijay

Subject: [rules-users] Drools Guvnor installation on weblogic
Hi All,
I am trying to install Drools Guvnor on weblogic 10 .I have added the Guvnor WAR file and
dependent jars from Drools binaries download.
However I am getting error for datasource configuration. Do we need to configure any
datasource?
Please find error logs below
