Stupid person question about EOAdaptor and Class Cast Exception and error message

I have just installed the EXExtensions, ERJars, and ERJavaMail  
frameworks to resolve an e-mail problem. E-mail now works. So far so  
good. But  now I'm getting an error on a save where previously things  
had run smoothly. My chief problem is that I don't know how to read  
the log to locate where my class cast exception is.

Does anyone know where this is directing me to look in my java files,  
WebObjects Builder files or EOModel?
