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.

my advice... don't mess with it...

have a look at

http://twittercfc.riaforge.org/

it's a simple cfc which uses cfhttp and is simple to implement and is -safe-

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 ;-)
