Really Really Tough Bug in JSP

[ajt111]

***************WARNING***************
The following code is not good.
It is a result of 3-4 developers over 2-3 years.
I have now been assigned the task of "fixing" it.
*************************************

I will attach all files that I mention in this post.
I am pretty much at a loss as to what is causing this error.
Any help would be greatly appreciated!!
This project uses hibernate and JSP along with JSP.

This is where you should star:
submission-admin-resolve.jsp line 45 has this tag:

<t:htmlTag value="div" rendered="#{AdminSubmissionBean.isAdmin}">
			<s:gridEditor id="grid-slave2"
				rows="#{AdminSubmissionBean.rowsSlave2}"
				columns="#{AdminSubmissionBean.columnsSlave2}"
				values="#{AdminSubmissionBean.valuesSlave}"
				rowGroups="#{AdminSubmissionBean.rowGroupsSlave2}"
				fieldTypes="#{AdminSubmissionBean.fieldTypesSlave}" />
		</t:htmlTag>

which produces this error:

The query run to retrieve data from the table for the bean AdminSubmissionBean contains a request for a column called pur which is not on the table in the database or simply the SQL syntax was wrong.
If you did not write any queries then a property in one of your entities is marked as a persistable property (called pur) but the table mapping to that entity does not contain that column.
