JSP how to retrieve a return value from an include?

hi!!!

i'm including an jsp-site
with <jsp:include page="mypage.jsp" flush="true"/>

how can i get some values from this include???
that means: i'm processing something in the include and want to return it to the site where i include it...

how can i manage this, or how can i solve this problem in different way?

i'm running jsp on tomcat 3.21

thx ahead s.

You can use session variables. Use this in the include JSP:

request.getSession().setAttribute("yourVariableName", yourValue);

And use this in the JSP after <jsp:include page="mypage.jsp" flush="true"/>:

yourValue = request.getSession().getAttribute("yourVariableName");

Good luck!

I think you can use:
<%@ include file=File %> or <jsp:directive.include file=File %>

Dear cheeky

S_B will want to use a dynamic include (<jsp:include>), because he wants to do some processing in the page and return some results back to the calling page. So, the question is not whether to use dynamic or static includes, but how to return some values back to the calling page.

>or how can i solve this problem in different way?

I thought implied that he might want to use a different approach.

A different approach would be to write a bean and use it in the calling page.

Instantiating the bean:

<jsp:usebean id="myName" class="YourBeanClass" />

Getting a property value from the bean and inserting it
into the text:

<jsp:getProperty name="myName" property="myValue" />

cheekycj

How would the included file see the bean using jsp:include? or the calling jsp see any beans used by the jsp:include file?

CJ

dnoelpp

No, no, the bean is used instead of the included page.

cheekycj

OK. Yup, that would work.

Creating convenience methods on beans (to do what your JSP include was doing) is definitely an option too.

thx a lot for the answers...
even if they don't hit my needs 100% i'm sure i can use them otherwise...

(i'm, not able to use beans because this will be processed in a different framework and a few other things which deny beans...)
