I had to overwrite a tag from a custom Tag library due to a bug inside. I copy-pasted the complete code of the class (cannot subclass, bug located in private method) in my own custom class, I created my own .tld file with a new shortname property and added the reference in my web.xml file. Then I updated my jsp-pages using the new prefix.
Now I get the following error:
Error failed to locate setter method for attribute class in tag class my.package.MyTableTag
The field it is complaining about is explicitly defined in my custom class, so I don’t understand why I get this error.
Any help would be greatly appreciated, if more information is required ask away!
Edit
I examined somewhat further and I think it should have something to do with the tei-class which is defined for the original tag (and my custom copy). But inside this class I cannot find anything that directly references a wrong class or something similar.
The application is deployed on a WAS 6.1 server and the error stacktrace starts with:

Found another workaround using a subclass instead of the copy-paste class!
