This is how I understand your problem .... While trying to display some data on JSP you are getting a collection not found error.
Are you using struts taglib ?
To nail down the problem .. try to find the line ... which if removed from jsp resolved the error ... then post that line ... I have a feeling that (if you have logic:iterate) the collection used is coming up as null ... try initializiting it as new ArrayList or similar ... alternatively try if its not null by using logic tag or simpler still a scriptlet (to debug)...
do post the line which if removed resolves the error.

Struts is a presentation-oriented framework. Struts classes should not be coded to connect directly to a relational database. Correct usage of Struts is the application of the Model View Controller design pattern. Struts provides a skeleton (supporting classes) for the View and a Http-based Controller.
A Model application contains the code that connects to a relational database.
