You can't really do that. A .vm file requires a "context" which is provided by the code behind it. You can't just take a .vm and render it from elsewhere because the context for it won't be there in your code. You can, of course, create your own context for a .vm file provided elsewhere, but you might as well just copy the .vm into your own plugin as you're already doing all the rest of the work.

but why jira webwork1 module type can do that.

It can't - it's providing a context and reusing a file. It's not rendering it without a context as you seem to be trying.

you are right, thanks.

The jar plugin is a simple zip archive. Unzip the plugin you want to get vm from and copy vm into your plugin. Then render that according to your needs. Please note that you should provide needed variables to that vm file to render it. Also please note that there might be some license issues that will not allow to do that legally.

Yup, as I said, copy it into your own code.

currently, when i call render function, velocity tell me can't find the resource file. i known why raise this error, because of not using the right classloader, so classloader can't find the resource in current bundle. but anyone can help me to resolve the question.
