Hi

I have a project that uses Spring 3.0.7 and i'm trying to implelment JBPM 5.2 in it (currently using JBPM 4).

I added code to my mvc-config.xml as specified in the official user guide of JBPM 5.2 but when i run the project it throws this error:

org.xml.sax.SAXParseException : Attribute "schemaLocation" bound to namespace "http://www.w3.org/2001/XMLSchema-instance" was already specified for element "definitions".

I see it has something to do with xml's namespaces but i have no idea why it is hapenning and how to fix it.

this is the beginning of my mvc-config.xml:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

          xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p"

                    </jbpm:resources>

any help would be greatly appreciated...
