Whenever you see: "(Unsupported major.minor version 48.0)"
It is because you have a class (or library in this case) that has been compiled with a newer version of the JDK than you are running it with.
What version are you starting Websphere with? If you can upgrade it to 1.5 it should work... (maybe even 1.4? depends on which version they compiled displaytag with)

Hi, I'm new to this list and I'm trying to get the 1.1 version of the
displaytag library to run and having some troubles. I'm using Websphere
5.0 which uses J2ee v1.3 and have the jar file copied to my WEB-INF/lib
folder and here is my entry from my web.xml:
<taglib>
<taglib-uri>http://displaytag.sf.net</taglib-uri>
<taglib-location>/WEB-INF/lib/displaytag- 1.1.jar</taglib-location>
</taglib>
Here is my tag description in my jsp page:
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
When I compile/run my application I receive a "unknown tag
(display:table)" and I get the following output:
"Error 500: LinkageError while defining class:
org.displaytag.tags.TableTagExtraInfo Could not be defined due to:
org/displaytag/tags/TableTagExtraInfo (Unsupported major.minor version
48.0) This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class that
has an incompatible method signature........"
And then it proceeds to the output dump. I have updated all the
libraries listed in the dependencies page, but still no luck.
Any help and/or pointers to get this working would be greatly
appreciated...
Thanks
