Double @include error

["Shun, Vadim" <VS...@newcorp.com>]

Hi,

I am using Tomcat 3.1 on Windows 2000 (hmm!).
I attempted to include the same JSP twice and received an error.
Something like 

1.jsp:
Some HTML
<%@ include file="OptionMonth.jsp">
Some other HTML
<%@ include file="OptionMonth.jsp"> 
Some HTML

Here Tomcat kicked the following error error:
"org.apache.jasper.compiler.ParseException: Seen file \jsp\OptionMonth.jsp
already, maybe this is a recursive include?!"
The exception is kicked by PushFile function.

I opened JSP 1.1 spec and could not find anything that would require a
container to prevent duplicate includes. To me it looks like it might be
container implementation fault, which probably uses included file as a key
into the Hashtable. 

Or am I wrong and there is some good reason not to include the file twice?
In my case, I just had some long information which appears in several
places.
Do I have an alternative except taglibs to achieve this?

Thanks,

yes that's correct the reason is that <%@ include file="filename" %> works
like #include in c++ it just pastes the file into the jsp before it is
compiled.
