Create of BPMN XML failed - where is log file

[vreznikov]

Hi,
I've created a process in Modeler. An attempt to deploy my process in activiti-explorer failed with a blink of an error message "Create of BPMN XML failed".
I cannot find any meaningful error messages in the tomcat log files and I don't see any activiti specific log files as well. Where can I find any information about what was wrong in my process. I was trying export bpmn20.xml file but it failed with "parsing" error. again there is no information about where my problem is.
I need to create a demo (sort of PoC) and this is a show stopper…  
Vladi.

What is your logging config? What is activiti's log level? (Try to set it to debug).  But still there should be message in the log in case of failure. I did not have problem with error finding.
Another possibility is to debug it. (but try to find logs first)

Martin,

Thank you for the prompt reply.
I used DEBUG mode for log4j but it gave me no information at all.
Tomcat-stdout had the following

This is on attempt  to export the model. 

It looks like an attempt to deploy that model has no error messages in the log files at all.

I do understand that building/debugging activiti might produce some information however this is not an option for us. The idea is that business analyst is building models in Modeler and deploy them. Business analysts are not java developers…

Any further idea?

You could share the process model (export it instead of deploying it) on the forum. A declared edge seems to be missing, but we can only know what is causing this if we can see the xml.
