MarshalException calling workflow services (openkm 5.1)

Hi, I seem to be having issues with calling workflow services. If I try to do anything against workflow (like simply getting the Process Instance for example I get the following exception
Code: Select all

I am able to authenticate without a problem but as soon as I try to do anything again the workflow there is a problem... It appears to be only at the
point where a response is to be generated. The request actually doe s the work (in the instance where I send a signal to a process instance for example, the
signal is sent but the service fails to respond because of this error.

any assistance would be appreciated. I am using OpenKM 5.1 community edition
thanks
Paul

On further investigation, it seems actually as though there is an issue with having any formelements in your workflow. I have added
Code: Select all
@XmlSeeAlso({com.openkm.bean.form.FormElement.class
			,com.openkm.bean.form.Button.class
			,com.openkm.bean.form.Input.class
			,com.openkm.bean.form.Text.class
			,com.openkm.bean.form.CheckBox.class
			,com.openkm.bean.form.TextArea.class})
to the ProcessInstance class and now I at least get a response from the service (soapUI works fine after that). The issue now is that I cant seem to unmarshall the thing for some reason (even though I have generated a new client jar).
Is this a known bug in the OKMWorkflow service or am I doing something horribly wrong here. Its seems very odd that I would be the only person struggling with this.

thanks
Paul

For what I'm seeing you're accessing workflow via webservices, on which method do you got this problem ?

Hi, apologies, I thought I was being explicit with my description there.. Yes, I am calling workflow through the webservice api.
Any method that would result in a processinstance being returned will not marshall correctly if you have formelements as variables
in the workflow at all. I am simply calling getProcessInstance.

thanks

A couple of questions:

1.- Which OpenKM version are you using?

2.- Are you deploying OpenKM in the default JBoss bundle?

Please, attach a sample webservice client to test.

Anyway you should try OpenKM 6.2.0

thanks, 6.2 is not an option for us at this late stage of our developemtn lifecycle. not without serious risk.
