The value for the useBean class attribute com.company.product.thing is invalid

[Julie Larson]

Hello,

I'm sorry to pester the whole world, but a search turns up no more
meaningful information that I haven't explored already.

I'm using Tomcat 5.0.24 and encountering a maddening problem.

Is there any known cure for this?

I'm using all public constructors that take no arguments.

The package path is correct in the WEB-INF classes folder and in the
jar as well.

Thank you for any additional suggestions that might help!

Not sure if it is the same issue but I had the same problem when
moving to JBoss with Tomcat. I found an option in the web.xml file
called errorOnUseBeanInvalidClassAttribute which defaults to true. Set
this to eb false and it stops jasper from throwing the Exception if
the class is not a bean.
