Process Definition XML Validation Problems

[caleb.powell1]

Hi,

we are trying to parse a very simple process definition xml file. We are using the following environment:

-jbpm 3.2.2ga
-XercesImpl 2.2.1 paser on the Classpath
-Java 1.4.2_13

When we attempt to load the xml, the validation is failing. We suspect that there is nothing wrong with our xml file, and in fact, the problem lies with the xsd. This is the xml we are trying to parse:

<process-definition xmlns="urn:jbpm.org:jpdl-3.2">
<start-state>
<transition to='s' />
</start-state>
<state name='s'>
<transition to='end' />
</state>
<end-state name='end' />
</process-definition>

We get the following exception from jBPM:

org.jbpm.jpdl.JpdlException: [[ERROR] line 366: cos-ct-extends.1.4.2.2.2.2.1: Error for type '#AnonType_assignment'. The content type of a derived type and that of its base must both be mixed or element-only., [ERROR] line 1: cvc-complex-type.4: Attribute 'name' must appear on element 'process-definition'.]
at org.jbpm.jpdl.xml.JpdlXmlReader.readProcessDefinition(JpdlXmlReader.java:172)
at org.jbpm.graph.def.ProcessDefinition.parseXmlString(ProcessDefinition.java:151)

We've seen this problem posted before with no responses. Does anyone know why this is happening? Is it a problem with the xsd or are we doing something wrong?

Thanks,

Caleb

As is is written in the exception, you must add a name to the process definition.

form the todo example:

<process-definition
 name="todo"
 xmlns="urn:jbpm.org:jpdl-3.1"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="urn:jbpm.org:jpdl-3.1 http://jbpm.org/xsd/jpdl-3.1.xsd"
 >

at least, add the name="[a name here]" and the validation should pass

Hi Phong,

thanks for your reply. I added the name attribute as well as the other attributes and validation still doesn't pass:

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="urn:jbpm.org:jpdl-3.1 http://jbpm.org/xsd/jpdl-3.2.xsd"
 name='todo'>
 <start-state name='a'>
 <transition to='s'/>
 </start-state>
 <state name='s'>
 <transition to='end'/>
 </state>
 <end-state name='end'/>
</process-definition>

Any other ideas? Can anyone else reproduce this problem?

n.b. For the record, we were actually trying to parse a much more complicated process definition and resorted to a simpler version to try and figure out what was going wrong. I omitted the name in the simple version. Thanks for pointing that out.

your schemalocation is wrong. There is a urn:jbpm.org:jpdl-3.1 in there which should be 3.2

[caleb.powell1]

Hi kukeltje,

thanks for catching that. I made the change to the following;

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="urn:jbpm.org:jpdl-3.2 http://jbpm.org/xsd/jpdl-3.2.xsd" name='todo'>

But it still hasn't resolved our issue. I will try a different version of the xercesImpl.

Regards,

Caleb

I upgraded the xercesImpl library to 2.4.0 and it resolved the problem. Thanks to everyone for your help.
