Hi,

I got the same problem. Just wonder whether you have solved it or not?

Could anyone out there please help us know how to solve this?

Many thanks,
Van

[vanho]

Hi,

Not sure if this is the solution for this problem. But when I changed to use
jdk1.5.0 instead of j2sdk1.4.x, the exceptions disappeared.

Cheers,
Van

[kukeltje]

what appserver are you using and what version of jBPM?

[vanho]

Hi,

I'm using the lastest JBoss and jBPM versions, i.e. JBoss 4.0.4 CR2
and jBPM 3.1.

I had a similar problem, and was able to make it go away by putting the Xerces .jar files in my classpath. I think it has something to do with validating XML parsers, and the JDK 1.4.x doesn't support those features (or something like that).

[jtigger]

The SAX2 parser that comes with the JDK 1.4.x (crimson) does not support XMLSchema (it uses DTDs for document structure). jBPM defines JPDL in XML Schemas, not DTDs, so you need a parser that supports .xsd.

The exception being thrown is saying, "you're trying to set a SAX parser property and the current XML reader doesn't grok that property". In this case, the property is "http://java.sun.com/xml/jaxp/properties/schemaLanguage"

Xerces's parser DOES support XMLSchema. When you toss in the Xerces JAR (I'm using 2.8.0), the JDK quietly defers to the included parser.

In JDK 1.5, Xerces is used as the parser in the JAXP default implementation. So, in JDK 1.5 XML Schemas are supported out-of-the-box.

Hello to all,
I have to re-open this thread again, because I got the exception even so I'm using jdk 1.6. I want to post my Exception:

so now my question. Can I resolve the problem if I use a new xerces-j api(2.9.2)? And if so, how can I use this instead of the classes contained in the jdk1.6? I tried to add the xml-apis.jar(xerces-j 2.9.1) to my classpath but it didn't help. Or can I do something with that 'jbpm.cfg.xml' mentioned in the [info] above?
hope you can help me.

overriding xml parses is a jdk issue (search for 'xml and parser and endorsed' on the internet
