Hi All,

I have a header.jsp, viewBankInfo.jsp and footer.jsp.

header.jsp - has conn object in the scriplet <%Connection conn = DBMgr.getConnection(); %>
footer.jsp - should be able to close the conn "conn.close()"

ViewBankInfo.jsp - includes both header and footer.  I want to use "conn"  object in

<%@ include file="header.jsp"%>

conn.executeStmt();

<%@ include file="footer.jsp"%>

The problem is that viewBankInfo.jsp doesn't recognise variable declared in header.jsp. Isn't "include" directive allows us to use variables declared in including or included pages ?



Help would be greatly appreciated
Thanks
Dasari

How about placing the 'conn' object into the current HTTP request as setAttribute("conn", conn);
and calling getAttribute("conn") in your footer.jsp

Hi

Thanks for the quick response. There might be many variables that we want to use in across the pages. so i am not sure if we want to put all of them in the request object. But shouldn't the include option already gives us access to the variable. When the jsp is compiled into servlet it is compiled by including all the pages into one page. So the variables should be available.

ideally speaking include file should be working and you should be able to use the variable out there..
can you post the headr.jsp and bankinfo.jsp so that we can look in to it?
what is the exception you are getting while compiling??

it definitley should be <%@ include file="header.jsp"%>.

here are 3 files :-
header.jsp:
<%int i=0;%>
<%=i%>

footer.jsp:
<%=++i%>

and page.jsp
<%@ include file="header.jsp"%>
<%=++i%>
<%@ include file="footer.jsp"%>

the output is:-
0 1 2

you problem is likely to the syntax - I can have a look if you want.
what server are you using?
