Abends in JSP with “Unable to find a value for "reason" in object of class "java.lang.String" using operator "." “ ( I believe I'm getting this because my “histDB” object is null ? Does any one see my problem in the code ? Thanks

Code in Servlet:

You're asking us about some JSP code, but you haven't posted that code. Which makes it a bit difficult...

Anyway the error is saying "You asked me to evaluate the getReason() method on a String". You wouldn't get this error if you tried to evaluate it on a null reference, the JSP processor would just ignore that. So look at your code and find out why you attached ".reason" to a variable which is a String and not a ViewHistDB object.
