JSP Tag -- Including a JSP fragment in a Java Tag file

Hi all,
I have a query regarding JSP Tag file authoring by extending the TagSupport class. I would like to know if it is possible to include a JSP file fragment inside a Java file somehow.
Specifically, I have created a simple template tag, which adds a header and footer template to the resulting HTML page.
<bc:template>
Hello World!
</bc:template>produces for example
<html><body>
Hello World!
</body></html>Now I have two JSP fragment files (head.jspf and foot.jspf), and I want to do do something like
public class HtmlTemplateTag extends TagSupport implements TryCatchFinally {
public int doStartTag() {
    // somehow include head.jspf
    return EVAL_BODY_INCLUDE;
public void doFinally() {
    // somehow include foot.jspf
}Which means, I want to execute had.jspf and foot.jspf from the Java class file. I am not sure if it is even possible. If anyone can help me with this, it would be greatly appreciated.
thanks
nilesh

Your intention is to put a header/footer on pages in your web application?
There is another way to do it - specify prelude/coda jsp fragments in web.xml
Something like the following:
<jsp-config>
<jsp-property-group>
    <url-pattern>*.jsp</url-pattern>
    <include-prelude>/WEB-INF/jspf/head.jspf</include-prelude>
    <include-coda>/WEB-INF/jspf/foot.jspf</include-coda>
</jsp-property-group>
<jsp-config>

Unable to run jsp as include using jsp:include tag

I am trying to run the basic jsp:include sample provided by Oracle in OC4J 10g. When I run the code, It seems like include file is treated as text/html and not run at all. Can somebody help me in figuring out what I am missing here..
Here is the code for main.jsp
<jsp:include page="content.jsp">
<jsp:param name="a" value="1"/>
<jsp:param name="b" value="2"/>
<jsp:param name="c" value="3"/>
</jsp:include>
Here is the code for content.jsp
<p> Included Content </p>
<p> Parameters - ${param.a}, ${param.b}, ${param.c} </p>
When I run this code in JDeveloper10g using the embedded OC4J as well as Application Server 10g, I get the following output.
Included Content
Parameters - ${param.a}, ${param.b}, ${param.c}
Note that the parameter values are not substituted properly.
Thanks in advance

Include a JSP inside another JSP

Hi SDN,
I am stuck with a problem. There is a JSP file available. In this JSP I have to add some more fields. But when I try to ad new fields I am getting a Portal Runtime Error stating that "Code Too Large". So now I thought of putting the new code in another JSP and include that JSP inside my main JSP. Here I cannot use <@include file="..."> because this finally compiles both the JSPs as one.
So I tried to use <JSP:include>. Some one please help me with how to include a JSP inside another using <JSP:include>. Here both the JSPs are having HBJ content inside.
I know that <jsp:include page="relPathOfChild.jsp"/> will include the child.jsp into my main jsp. Problem is both the JSPs are having HBJ content, so If I dont declare <hbj:content> tag inside the child jsp, it is throwing an error. But If I declare a <hbj:content> tag inside my child jsp, only child content is coming and main jsp content is not coming.
Please help me..

Hi,
This Problem is solved. Now I am able to include a child JSP inside the parent JSP. But now the problem is,

JSP Error: Include limit reached

Hi All,
I am developing on iAS 6.0 SP1 on WinNT. I have my initial index.jsp
which uses
<%@ include file=xx.jsp %> to layout the main page depending on a set of
session values.
At the moment I have about 31 such includes. But I get the following
error with that jsp.
I remember there was a limitation of 20 includes in NAS 4.0.
I feel that same limitation is with iAS.
If so is there a way to overcome this limitation?
TIA

Hi,
CALCLIMITFORMULARECURSION configuration setting is not valid for ASO cubes and only applies to BSO cubes. The equivalent configuration setting for ASO cubes is MDXLIMITFORMULARECURSION.
Syntax
MDXLIMITFORMULARECURSION TRUE | FALSE
TRUE - Imposes a limit of 31 on the number of MDX formula execution levels. The default setting is TRUE.
FALSE - Imposes no limit on the number of MDX formula execution levels.
Description
MDXLIMITFORMULARECURSION limits the number of execution levels of MDX calculated members or formulas. MDX calculated member or formula execution may be recursive (for example, a formula can refer to itself, or a calculated member can refer to itself). By default, Essbase limits the number of MDX formula execution levels, because formulas with excessive execution levels may lead to stack overflow errors and crash the server. However, setting MDXLIMITFORMULARECURSION to FALSE prevents Essbase from imposing the limitation. You can use this setting when you know that a recursive execution in a formula/calculated member will eventually terminate, and you wish to have a recursion depth greater than 31.
If an MDX formula reaches 31 execution levels and MDXLIMITFORMULARECURSION is not set, or is set to TRUE, Essbase stops processing that formula and writes
error messages in the application log. If a formula reaches 31 execution levels and MDXLIMITFORMULARECURSION is set to FALSE, Essbase continues processing that formula.
CAUTION: before setting MDXLIMITFORMULARECURSION to FALSE, be sure that the MDX formulas in the outline are not infinitely recursive; for example, be sure that formulas do not depend on each other. Infinite formula recursion may crash the server.
This is a known issue and is fixed in version 11.1.1.3.500 and you may consider upgrading Essbase.

I'm guessing that I might be missing some other jsf tag inside the jsp fragment. Any help will be greatly appreciated.

I can suggest you with the following solutions
1. try having <%out.flush();%> before and after c:import
2. try with jsp:include with flush=true
Can you reply back with which one works? I didnt try out both of them
Thanks

In custom tag, trying to include JSP page, not processing JSP tags

I am in a custom tag where one of my attributes (myIncludePage) is the name of another JSP file that I want to include. So in my custom tag doStartTag() I have:
out.println("<td>");
pageContext.include(myIncludePage);
out.println("</td>");
The included page is rendered with the custom tags in it not processed (I see my tags in the generated HTML)
How do I get the included page to be "processed"
Thanks in advance

Sorry, wrong forum, should be in the JSP forum. Hope someone can still help!

Are not interpreted JSTL tags in a JSP page including in a servlet.

Hi people,
I have a project where una page (index.jsp) includes a servlet (MyServlet), that consult a persistence class and get a List of objects (Users),
then the servlet passes the List to a Request object and includes another JSP page (showUsers.jsp). And this is conceptually correct, but don´t works, the JSTL tags are not interpreted in showUsers.jsp.
This is my code...
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

<c:out value="Show me some things index.jsp"/>
<div style="border-color:red; border:solid; padding-left:60px">
      <jsp:include flush="true" page="pepe/MyServlet"/>
</div>
</body>
</html>...and the Servlet...
public class MyServlet extends HttpServlet
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
          UserManager um = new UserManager();
          List users = um.getUsers(); //This use Hibernate to return a Users List
          request.setAttribute("users", (ArrayList) um.getUsers());
          request.getRequestDispatcher("/showUsers.jsp").forward(request, response);
}...Finally, we have the showUsers.jsp file....
<c:out value="Show me some thing showUsers.jsp"/>
<table>
     <tr>
          <th>ID</th>
          <th>Name</th>
          <th>e-Mail</th>

I assume in your web.xml, you have ''pepe/MyServlet' defined as a servlet tag and servlet map tag? Without that, I don't think your JSP will find the servlet. I'm >not sure you need it in web.xml since I never call a servlet from a JSP page.
I suggest putting System.out.println() throughout your servlet code and out.println() in your JSP pages to see exactly what is called and when.
As a general rule, JSP files are to display data only, and submit back to a servlet. The servlet does all the business logic and dispatches to the appropriate >JSP page. The JSP shouldn't have any business logic. Including the servlet looks kinda like including business logic. Actually, in a MVC design, your >presentation, control, busines, and database layers have their own isolated responsibilities.
I suggest the servlet put data as one java bean in request scope via request.setAttribute() and dispatch to the JSP page. The JSP page gets the data via ><useBean> tag. The JSTL gets the variables from the useBean tag and uses the data from there to display it. Really, this is my web.xml file...
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          <url-pattern>/pepe/MyServlet/*</url-pattern>
     </servlet-mapping>
</web-app>Regarding putting System.out.println() and out.println(), i did it and thats works.
Respect of your last comment, I am not a expert in MVC, but I understand that the view layer can make calls to the Controller layer, I am wrong?
evnafets wrote:
It's not. However thats not code, but the generated HTML.
As Balusc pointed out it's the result of running this JSP page without importing the tag library at the top.
Because the tag library is not declared, it treats the <c:forEach> and other tags as template text, and basically ignores them.
It then evaluates the ${items} attribute as an expression in template text, calling toString() on it.
Cheers,
evnafets      The file showUsers.jsp are included into the index.jsp page, that's have the header taglib. Could this works?

Include tags within a JSP block (making readable code)

I've created a page that includes segments of other pages based upon a condition passed via a parameter. Arg! Let me start over.
My code looks something like this...
<%
   String foo = request.getParameter( "action" );
   if ( foo == null ) {
%>
      <jsp:include page="error.html" flush="true" />
<%
   } else if ( foo.equals( "add" ) ) {
%>
      <jsp:include page="add_user.jsp" flush="true" />
<%
   } else if ( foo.equals( "help" ) ) {
%>
      <jsp:include page="help.html" flush="true" />
<%
   } else {
%>
      <jsp:forward page="display_status.jsp" flush="true" />
<%
%>And obviously, this is kind of hard to read. Is there a way that I can do includes and forwards within the context of the JSP block itself? I'm looking for something like...
<%
   if ( foo == null ) {
      this.include( "error.html", "true" );
   } else if ( foo.equals( "add" ) ) {
      this.include( "add_user.jsp", "true" );
   } ... else {
      this.forward( "display_status.jsp" );
%>...which should hopefully be a lot more readable.

for example
<jsp:include page="text.jsp" flush="true" />
is equivalent to
<% JspRuntimeLibrary.include(request, response, "text.jsp", out, true); %>
ugh...
There should be more simple solution.

Use var of sql:query tag into a jsp fragment code

Hi, i'm spanish and my english is not very good XD.
I need to use some data from <sql:query> tag into code jsp <% %>
EXAMPLE:
<sql:query var="variable">
</sql:query>
<% what can i do to access to "variable" here????????? %>
i need to save in session (session.setAttribute(...)) a field of the response of the query saved in "variable"
i need help!!!!, thanks!!!!!!!!

i need to save in session (session.setAttribute(...)) a field of the response of the query saved in "variable"Why do you need java code to do this? If you are using JSTL sql tags, then why not keep using JSTL tags?
<c:set var="valueToSave" value="${variable.field}" scope="session"/>EL variables are actually already stored as attributes in scope.
So to get hold of "variable" you could use <%= pageContext.findAttribute("variable") %>
and that would give you the object stored by the EL.
cheers,

Weblogic 9.1/10 not working on jsp:directive.include file="file.jspf"/

Does anyone know how to get rid of this problem? I have a jsp page including a sun java studio creator created page fragment using the tag:
<jsp:directive.include file="myHeader.jspf"/>
here myHeader.jspf is a page fragment.
after deployment, weblogic server report error as:
weblogic.servlet.jsp.CompilationException: Failed to compile JSP /Page1.jsp
Page1.jsp:15:57: Error in "C:\bea\user_projects\domains\base_domain\servers\AdminServer\tmp\_WL_user\proj\grb4mk\war\myHeader.jspf" at line 1: The encoding "null" specified in the XML prolog is unsupported.
<jsp:directive.include file="myHeader.jspf"/>
^----------------^
Any idea? I tried both weblogic 9 and 10, same error, change to
<jsp:include page="myHeader.jspf"/>
works. the question is: why not read jsp 1.2 tag? Any way to make it work with jsp:directive.include tag?
thanks in advance.
Edited by: user10243594 on Sep 10, 2008 10:22 AM

The "jsp:directive.include" tag is only valid in an well-formed XML file that specifies all the relevant namespaces. The "jsp:include" tag is used in a JSP file. I'll bet the beginning of your file shows that you don't have a valid and well-formed XML file.
If you found that "jsp:include" worked, then that confirms you have an ordinary JSP file here. Why are you trying to use the XML form? The result of "jsp:include" in a JSP file will be exactly the same as the analogous tag in an XML file.

Include directive to include a JSP file from a JAR file

I have an Eclipse project in which I have placed a JSP file in the package structure with the rest of my code. This is in fact only a code snippet page, not a full blown JSP file.
I have a second project that is a Dynamic Web Project in Eclipse that incorporates the first project as a JAR in the /WEB-INF/lib directory.
In this project I have a JSP file and I want to include the JSP file embedded in that JAR file.
How do I do that?
I'm thinking the only real solution is to rewrite the snippet portion as a custom tag.

The JSP fragment page in question is actually a HTML form page. It is a form to be used specifically by a particular servlet. That is why they are "bundled" together in the same project, in the same package structure.
I have multiple web applications that I want to include that form/servlet, so it gets added to these projects in the /WEB-INF/lib folder as a JAR library. But I don't want to recreate the form over and over again for each application. It would be nice if I could write a JSP page that wraps the fragment using an include directive to bring that fragment into the new page.
So to do that with any other fragment I would write:
<%@ include file="/WEB-INF/jsp/SOME_FORM.jsp" %>
which works great if my fragment page is in the /WEB-INF/jsp subfolder. But if I want to access the JSP fragment as it is bundled in a JAR file, this:
<%@ include file="/WEB-INF/lib/FORM.jar/SOME_FORM.jsp" %>
doesn't work so good. It's just all wrong.
I was wondering how I could just write one include statement to get what I need. There are work-arounds galore, but I thought if I could get this working it would be the simplest solution overall.

How to use Flex tag library in jsp

Hi All,
We are planning to use flex in our J2EE application in order
to show some charts. Our j2ee application is in JSP,Struts. I have
searched on google about this and found that I can include flex 3
tab library in the jsp in order to use mxml tag in the jsp. I have
written a sample program in the jsp which uses flex.
<%@ taglib uri="FlexTagLib" prefix="mm" %>
<SCRIPT LANGUAGE="JavaScript">
function showMessage() {
message.value = "Use this application wisely";
function hideMessage() {
message.value = "";
</SCRIPT>
<mm:mxml border="5" onmouseover="showMessage();"
onmouseout="hideMessage();">
</mm:mxml>
<TABLE>
<TR>
<TD><input type="text" name="message"
size="50"></TD>
</TR>
</TABLE>
I have added entry inweb.xml. See below,
<taglib>
<taglib-uri>FlexTagLib</taglib-uri>
<taglib-location>/WEB-INF/tlds/flex-bootstrap.jar</taglib-location>
</taglib>
Following are the problems that I am currently facing.
1) Could anybody let me know whether the entry of
<taglib> tag is correct in the web.xml. Is it the correct
jar(flex-bootstrap.jar) that I should include?
2) If yes, from where to download it? or
If no, what is correct jar that i should include and how?
your response will be highly appriciated as this is the major
requirement in our project?
Thanks ,
Chandan

In portlet context include a jsp from the desktop context

Hi,
I developed a portlet, and in my jsp file I want to include a jsp file which is in my portal desktop (the file is in /etc/opt/SUNWps/desktop/..).
So I want to do something like:
<c:import url="file:///etc/opt/SUNWps/desktop/mydesktop/ PortletHeader.jsp" /> Of course this doesn't work because the jsp expressions are not executed, instead the jsp tags are just displayed in the browser.
but for including a jsp with <@include file> or <c:import> or <jsp:include>, the jsp must run in its context. So actually we should do something like <c:import url="some_path" context="some_context" >.
Now, I don't know what some_context is. To what context the portal desktop runs so the jsp file can be 'executed'?
Hope someone can give me some more information about this.
Greets,
Tim

<quote>some_context <quote>
..will be the pageContext
which is the implicit object for a JSP.
or
use config object to get this context and then use
<jsp:include> or <@include file>

Including a jsp on the same page by clicking a button

Hi,
I have a jsp page where there are many controls and some buttons. If I click a buton called "Edit" I need to include a jsp page below the existing controls.
Can someone please tell me how to do that?

<a><img name="Edit" src="edit.gif" border="0"/></a>
</td>
</tr>
this is thecode which I have for buttons in my page
Thanks

Using javascript, you could wrap the included page within a DIV tag or SPAN tag that is initially not visible. Then when the user clicks the button you would make the hidden DIV or SPAN visible.
The visibility attribute can be set to visible (to see it) or hidden (to not see it). Here's a page that might shed some light:

How can I include a JSP, Maximized, and retain look and feel(WSRP)

I have created a page group and defined a root page with a certain look and feel. There are two portlets on the page. Once the user clicks on a submit button, the portlet performs some action and includes a jsp included in the EAR file. The portlet needs to maximize the UI to display the jsp correctly.
Once control returns back to the screen, the look and feel is lost and uses Oracle's default style. I have two questions:
1. From the portlet, how can I retain the look and feel of the page group when referencing "external" jsp (i.e JSPs in the deployed portal EAR file).
2. How can I "redirect" the user to the home page in a standard way? If there is not a standard way, how do I use the Oracle specific utilities to do it?
All of my JSPs are developed externally out of the scope of the Oracle Portal.
Environment - Oracle Portal 10.1.4 on Release 2 using WSRP to contact Oracle Release 3, hosted EAR file (WSRP Producer).
Thanks in advance.

Hi José,
I don't think that is possible. But you can import the css files that ep uses for its look and feel and try to give your web pages similar look and feel. The tables and other controls used in EP are totally different and are done through complex JavaScript coding instead of simple HTML tags. If you want exact lok and feel then i thin you must go for a Webdynpro based application rather then a J2EE application with JSPs.

Guru.
