jBPM 4.1 - Spring Problem

nilspreusker Sep 24, 2009 6:47 AM

Hi,

I'm trying to integrate jBPM 4.1 with an existing spring 2.5.5 app and I'm getting the following exceptions:

1) Error creating bean with name 'jbpmConfiguration' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.jbpm.pvm.internal.cfg.SpringConfiguration]: Constructor threw exception; nested exception is java.lang.ExceptionInInitializerError

2) couldn't parse xml document : org.w3c.dom.DOMException: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified.

I've been trying to figure out what is causing this, but got completely stuck at this point. I'm assuming that something is wrong with my jbpm.cfg.xml, but the same exception occurs with an empty jbpm.cfg.xml or any other config I've tested (and I've used working ones from a jBPM 4 projects).
Maybe someone has seen this before? Here is the whole stack trace:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jbpmConfiguration' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.jbpm.pvm.internal.cfg.SpringConfiguration]: Constructor threw exception; nested exception is java.lang.ExceptionInInitializerError

Unfortunately the exceptions are missing crucial bits of information ("INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified", file, location and character could be displayed here).

Anyway, this is my jbpm.cfg.xml:

Nils,

This clearly is related to the xml parser that is used. There has been a previous post in this area in the forum afaik. Please try to find that article and see if it solves your problem as well (it is not jBPM related)

Roland, thanks for the quick reply! I upgraded to Xerces 2.9.1, which didn't immediately solve the issue, but gave a clearer error message. The next problem was that I had a dependency conflict between jaxb-impl-1.0.4 and JAXB 2.0... I posted details about resolving this on my blog at http://www.nilspreusker.de/2009/09/24/maven-dependency-conflicts/.

Cheers, Nils
