howto do dynamic inlude of functions in jsp

Mark asked
Last Modified: 2012-05-08
I want to call a function that returns a value which I will embed in my jsp output via <%=scIdMinLen()%>. Simple enough so far. I want to include this function's source at runtime. Also simple enough. The included file is shown below in the Code Snippet section and I can include it with:
<%@ include file="OH/stateFunctions.inc"%>

The tricky part is I want to include a different source depending on what state I am processing. I've tried the following:

<jsp:include page="<%=stateCD + \"/stateFunctions.inc\"%>" />

This syntax works fine if the file contains html, but for the source shown in Code Snippet I get:

An error occurred at line: 180 in the jsp file: /newCase.jsp
The method scIdMinLen() is undefined for the type newCase_jsp

How can I do this?

// Functions for Ohio
private Integer scIdMinLen()
    return 6;
private Integer scIdMaxLen()
    return 6;
