Re: Unsupported major.minor version 48.0

[Adam Greene]

Why are you using Eclipse, any particular reason, because you could use Forte for Java.  That's what I use and it has kicking JSP / Servlet support (especially in the 4.0 Early Access Version, just have to ignore an exception when it starts up). ----- Original Message ----- From: Newman, Scott To: [EMAIL PROTECTED] Sent: Friday, April 12, 2002 1:17 PM Subject: RE: Unsupported major.minor version 48.0 I made sure that everything was blown away under tomcat, and both jdk's.  I don't have cocoon installed.  The only thing I really have is tomcat and axis.  I'm starting to think it's the eclipse ide marking the classes as the wrong version.  I have it set to use the 1.3 jdk (the only one on here now), as well as making the classes 1.3 compatible and the source 1.3 compatible, but nothing seems to work.  This is driving me nuts.  I've made sure to rebuild the classes under the new settings, but to no avail.  I'm almost positive it's eclipse now.    Aaaarrrrgggg!!!!   -----Original Message----- From: Adam Greene [mailto:[EMAIL PROTECTED]] Sent: 12 April, 2002 11:16 AM To: [EMAIL PROTECTED] Subject: Re: Unsupported major.minor version 48.0   Make sure that you have deleted the files from your work directory under tomcat (they are simply compiled jsps so it shouldn't matter, but you never know), make sure that you do not have a newer copy of the tools.jar in your path (you will get that if you have Cocoon installed as well (like I did)). ----- Original Message ----- From: Newman, Scott To: [EMAIL PROTECTED] Sent: Friday, April 12, 2002 1:03 PM Subject: RE: Unsupported major.minor version 48.0   Does anyone know how in the name of all that's holy do I stop this error from occurring?  I've upgraded from tomcat 4.0.3 to 4.0.4-b2, unistalled jdk1.4, unistalled and re-installed 1.3.1_02 and nothing makes it go away.    Help me, cause I'm stoopid.

It mystified me, so I'm avoiding 1.3.1_03 in favor of either 1.3.1_02 or 1.4.0.  I'd sure be interested in what's up with this, as well!   -- Ivan   "Newman, Scott" <[EMAIL PROTECTED]> 04/11/2002

anyone get this error?  It seems that I don't really get it until I include a utility library that I made that gets included into the class that is called via axis.     Here's the trace:
