Include Servlet in JSP


Web tier: servlets, JSP, Web frameworks: Include Servlet in JSP

  1. Include Servlet in JSP (4 messages)

    I wish to include a file in JSP, but the file is result from database query.
    Therefore, i would like to call a servlet in JSP using the following tag:
    <%@ include file="XXX" %>

    However, the result came out with the following exception:
     generated the following parse exception: org.apache.jasper.compiler.CompileException:
     Bad file argument to include

    You may suggest that i straightfowardly include another jsp file and inside that jsp
    file call the database to get the data and present it. However, i wish to it in separate
    tier (business tier) in my servlet and business class. I feel weird when my JSP creating
    connection to the database because it suppose to be the presentation layer.

  2. Include Servlet in JSP[ Go to top ]


    I don't think you can (or should) include a servlet in a JSP. You can do either of 2 things:

    - use the servlet directly (without the JSP)
    - from within the JSP, call a Java-class which responses with the desired data to display, eg:
     <%= someClass.someMethod(someArg) %>
  3. Include Servlet in JSP[ Go to top ]

    You should use <jsp:include page="XXX"/> instead of <%@ include file="XXX" %>. The latter just means merging before compilation, which apparently not what you want to do. 'jsp:include' actually includes response from XXX into 'parent' JSP response.

    Thanks for the through explanation.
    I had solved my problem.

    why don't you have the servlet do the DB call and then forward on to the JSP instead of including the Servlet call in JSP. That would be more of a MVC II paradigm.
