Re: QuartzPlugIn for struts manual scheduling

[Ram]

Under the jgs-struts src

src\java\com\jgsullivan\struts\plugins\QuartzPlugIn.java

If you look in this source code PLUGIN_KEY is the key in the application
context. Using this you can access the scheduler .

Hope this helps.

 I am attaching the source here for your reference
