Coldfusion JRun Error

I'm getting this error message: (Unsupported major.minor version 49.0)

I'm following the instructions on this page: http://blog.webdh.com/index.cfm/2009/2/4/Update-your-Twitter-status-from-ColdFusion-using-a-JSP-tag-library and using the same example for updating Twitter status as used on the page.

After doing a google search on this error message, it looks like it's something to do with the version of Java on the server and how the Jar file was complied (which I don't have any control over to change). What can I do on my server to make this work? What are the site-wide implications of a change (ie, it's a 50,000+ page site with millions of viewers per month and I don't want to mess up the whole site!)

I'm new to Coldfusion libraries, JSPs, APIs, and the like, so a very basic explanation would be very much appreciated.

That's correct.  Recompiling the source or changing your jvm settings is the only way to make it work AFAIK.   If you can't recompile, that leaves changing your jvm settings - which should not be undertaken lightly as it many have unforeseen affects and/or complications.

So take SidFishes' advice - don't mess with it.  Try the CFC he mentioned instead.

No problem ... especially as SidFishes already did the hard work ;-)
