Workflow exception

Gururaj Aug 09, 2012

We migrated jira data from jira 3.10 to jira 5.1.0. I am getting an exception when trying to resolving an issue.

On the UI I am getting "Could not load validator class"

I have two questions:

1. Do I have to install any plugin?

2. If I have to install any plugin, will it work in OnDemand environment?

Thank you for answer.

1. It looks like you are missing a plugin, yes. Might be worth looking at the xml for the workflow and digging out the validator class name - pop that into the marketplace or google and you should be able to identify which plugin provides it

2. You can't install plugins in OnDemand - see but that does list the plugins that ARE available, and it might be that your validator is in one of them.

Thank you for the reply. From the exception I know it is opensymphony workflow. Not sure whether it is still supported on OnDemand.

Evrything will be opensymphony workflow. Look at the workflow XML and find the actual validator class as Nic suggested.

Thanks Jobin and Nic. I will check and I will let you know.

I think you'll find that it is Opensymphony that is running the workflow actions, and your workflow will have "please use class xx.yy.zz to validate this transition", and that class will not be opensymphony based.

In other words, I think you've read the error message as "opensymphony is missing a class", when what it's really trying to tell you is "opensymphony is trying to call some class outside itself, and that is not there"

By far the easiest way to see this is to open the xml for your workflow in a plain text editor.
