StAXSource exception in 5.12 default war

[tiesebarrell]

I downloaded the default distribution of the explorer war for the 5.12 release, but there seems to be a problem when deploying process definitions. The demo processes and other processes all fail to deploy because of a StAXSource error:

(snippet)
Can't transform a Source of type javax.xml.transform.stax.StAXSource
at org.activiti.bpmn.converter.BpmnXMLConverter.validateModel(BpmnXMLConverter.java:173)
at org.activiti.bpmn.converter.BpmnXMLConverter.convertToBpmnModel(BpmnXMLConverter.java:198)

The full stacktrace is below for a simple process. I'm using Tomcat 7.0.37 on Windows and JDK 1.7.0_02. The 5.11 war file deploys without a problem on the same Tomcat instance.

Has anybody else run into this?

We run into the same problem when integrate the activiti engine 5.12 into a JBoss 6.1 Application server.

JBoss Server is using the jre build in SAXParserFactoryImpl, which seem not to be compatible to a StAXSource. We are using the JDK 1.6.0_41.

DocumentBuilderFactory implementation: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl loaded from: Java Runtime
SAXParserFactory implementation: org.apache.xerces.jaxp.SAXParserFactoryImpl loaded from: Java Runtime
XPathFactory implementation: org.apache.xpath.jaxp.XPathFactoryImpl loaded from: jboss-6.1.0/common/lib/xalan.jar/
TransformerFactory implementation: org.apache.xalan.processor.TransformerFactoryImpl loaded from: jboss-6.1.0/common/lib/xalan.jar/

We had the same problem when upgrading Activiti (in Apache Syncope) from 5.11 to 5.12: everything fine with JDK 7, exception with JDK 6.

We solved by adding xercesImpl 2.10.0 as JAR dependency.

Hi,

Yes there's an error in the Explorer for JDK 6, we are working on fixing it.
It's the xalan.jar file that's causing these issues.
We'll release an updated distribution this week.

Best regards,

[ryanberg1]

Has this been resolved? Has the distribution been updated? I recently upgraded to 5.12 and I am still experiencing this issue.

EDIT: It appears that the nexus repo has not been updated since this was reported (based on the timestamps). But, from looking in Github, it appears this has been fixed in the 5.13 branch. Is there a patch for the 5.12 release?

Thank you.
-Ryan

[tiesebarrell]

AFAIK, yes. I believe the releases were replaced in Nexus. Try deleting local copies you might have and pull them back in using Maven.

[ryanberg1]

Thanks.  I was looking at the wrong nexus repo.  I was looking at:

https://maven.alfresco.com/nexus/content/repositories/activiti/ 

Instead of:

https://maven.alfresco.com/nexus/content/repositories/activiti-releases/

[yulinqiu]

The same problem happened when Using Jdk7 And Tomcat 7.0 to deploy Activity 5.15.

Should I upgraded to Jdk8 ?

[jbarrez]

No, we also use jdk 7 and tomcat 7.

When do you get the error and what are you doing to cause it?
