Dev Naga commented on TILES-276:
--------------------------------
Thank you so much Antonio.
I have downloaded the AddListAttributeTag and PutListAttributeTag java files
from svn and compiled it using Java5(by changing the project facets in
preferences) and copied the compiled version of those files into the classes
folder under its corresponding package. I got the following unsupported version
error occurs. Did i do anything wrong in it? Wont retrotranslator help here.
And I feel difficult to checkout each file from the svn repository. Can I have
the compiled version of jar file, please?
Error 500: LinkageError while defining class:

org/apache/tiles/jsp/taglib/PutListAttributeTag (Unsupported major.minor
version 49.0) 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. Dumping the current context classloader
