Am testing activiti inside the eclipse. Am going some where wrong in this but i dnt know what is that can any body help me in resolving this.

[frederikherema1]

What is the error-message shown?

Maybe a syntax-error here ( sourceRef-'thestart', should be '='):

<sequenceFlow id='flow1' sourceRef-'thestart' targetRef='ReviewPurchaseRequest' />

I don't see any activiti in your stack trace.  Are you sure this problem is activiti related?

[jagadeesh]

what is meant by stack trace?? i dnt know abt it.?

expalin me in clear steps how to create a process and run the process..?

[brsilver]

I am not an Activiti user (yet) but I can see that your code is not even well-formed xml, much less BPMN schema-valid. It had extra tags, missing tags, missing quote signs; did the graphical editor create that code?  Yikes. Also the process nodes need to be enclosed in the process element, and everything needs to be enclosed in definitions element. I fixed it up in external xml editor, so it is now well-formed and schema-valid.  But it is still not good BPMN.  You need a gateway somewhere and a sequence flow to Revise Purchase Request; right now there is no path into that task.

Hi Bruce,

This is certainly not XML produced by the graphical editor / Activiti Designer.
That XML is ofcourse well-formed.
It looks like handwritten XML.

Best regards,

[jagadeesh]

Yes it is hand written XML .what is the next step need to be done?? Please advice.

[frederikherema1]

You should make sure your XML-syntax is valid and it should conform to the XSD schema's. If you're using eclipse, all error will be shown in the XML-editor.
