Including JSP without repeating code

My webproject has multiple processes, which use JSP files which are included into the index.jsp by a view ID. For example index.jsp?id=4 includes the work_4.jsp file which has speficic code for that proces.
The problem is that I use a javabean which handles my select queries. Index.jsp uses this bean for displaying some buttons which are stored inside a MySQL database.
In the work_4.jsp which is included, I have to use the bean to get data. The problem is that i need to define the bean again, as well as the import of the class itself.
Is there a way to use the bean from the index.jsp inside the included work_4.jsp without redefining the javabean?
<%@
   // index.jsp
   import "queryhandler"
%>
   <jsp:useBean id="queryBean" class="queryhandler" scope="session">
     <jsp:setProperty name="queryBean" property="SQLString"/>
     <jsp:setProperty name="queryBean" property="SQLLabelMax"/>
   </jsp:useBean>
   <jsp:include page="work_4.jsp" flush="true" />
<%@
   // work_4.jsp
   import "queryhandler"
%>
   <jsp:useBean id="queryBean" class="queryhandler" scope="session">
     <jsp:setProperty name="queryBean" property="SQLString"/>
     <jsp:setProperty name="queryBean" property="SQLLabelMax"/>
   </jsp:useBean>
   ... some code ...Now I want work_4.jsp to look something like this.
<%
   // work_4.jsp
%>
   <jsp:setProperty name="queryBean" property="SQLString"/>
   <jsp:setProperty name="queryBean" property="SQLLabelMax"/>
   ... some code ...

I'm not sure if this is quite what you want but I tried the following and it works for me without the full jsp:useBean declaration in the included file. You don't need the import statement as long as the full package statement is in the "class" param of the useBean tag. I just stuck my bean in the WEB-INF/classes, so there's no package.

<jsp:include page="testinclude.jsp" flush="true" />
</body>
</html>
testinclude.jsp:
<jsp:useBean id="testBean" class="TestBean" scope="session" />
<jsp:getProperty name="testBean" property="firstName"/>
<jsp:getProperty name="testBean" property="lastName"/>

Repeater fails using {container.item} context within included JSP pages

Greetings,
I'm using Bea Workshop 8.1.2 and netui's based framework.
I'm experiencing a problem relating to the use of jsp:insert tags as a way of templating the code as to make it more maintainable and cost effective.
The problem arises when using repeaters and then binding a <netui> tag with a "container.item" context inside the included jsp page.
Example:
On a PageController we define on its scope a rather simple data structure:
public String[] array={"Item1","Item2","Item3"}
The associated index is as follows:
index.jsp
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<netui:label value="{container.item}"/><br>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
This works as expected, it prints the data in the array list. Fine.
Now, with the <jsp:insert> tag usage, we get two files index.jsp and body.jsp:
index.html
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<jsp:include page="body.jsp" flush="true"/>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
body.jsp
<netui:html>
<netui:label value="{container.item}"/>
<netui:label value="{pageFlow.array[0]}"/>
</netui:html>
With this example the {container.item} tag fails with this exception:
"Caught exception when evaluating expression "{container.item}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: com.bea.wlw.netui.script.xscript.IllegalContextStateException: The Tag "com.bea.wlw.netui.tags.html.Label@cb5dce" does not have a valid parent of type DataAccessProvider. The expression "container["item"]" requires a parent of this type."
BUT - and here is my problem with this - the label tag with {pageFlow.array[0]} PRINTS THE DESIRED ELEMENT.
Also, on an extended example with a <form> tag around the main index html and the array structure inside a FormData class, {actionForm.array[0]} ALSO PRINTS THE DESIRED ELEMENT.
Only {container.item} gloriously fails with an exception complaining about IllegalContextStateException.
This is a total nonorthogonal behaviour, the features do not work as expected and indeed, with the importance of repeaters for netui's development, this preclude us from the minimum standard for structured web application design.
Does anyone have any clue about this behaviour? If not a fix, at least an explanation...
Thanks in advance.

Passing javascript values to jsp without refreshing the page

Hi,
How do u pass a value of a javascript variable to the jsp without refreshing the page ?
For example, a file called test.jsp in which a javascript variable x contains value 254. I need to pass the value of x to a method declared in test.jsp(same page).

Hi Mona,
when i say refresh i do mean a blink of the browser.
This is a small example i wrote to show you how you can pass javascript varables to JSP variables. If you don't want the refresh to be seen by the user just include this code in a hidden frame on a page and instead of refreshing the entire page, refresh the hidden frame.
i have to say, i didn't test the code so i don't guarantee it's flawless.
if you need an more detailed example just tell me, i'll create one, but it won't be for today :)
<html>
<head>
<title>Log in to the system</title>
</head>
<body>
<script>
//we retrieve the parameter 'user' from the URL
<%
String username = request.getParameter("user");
%>
var user = "<%= username%>";
//check if there is a username in the URL
if(user=="null")
//there is no username so we log the person in as a guest
user="guest";
//we refresh the page and set the user parameter to 'guest'
//the parameter now contains the javascript variable 'user'.
//The parameter can be read by the JSP (see the top op this script).
//This way we gave the javascript variabele to the JSP variable
location="login.jsp?user="+user;
else if(user=="guest")
{ alert("Welcome "+user+", I hope you like this site"); }
else
{ alert("Welcome "+user+", I'm glad to see you again"); }
</script>
</body>
</html>

Include jsp versus seperate class/bean versus taglib

Hi friends,
I am working on Servlet/JSP project. There are large no. of jsp pages. A common set of methods get repeated in all the jsp pages. Now my concen is to separate out the methods in a file and then use it in jsp page.
Kindly suggest me the right path to follow, taking into consideration that we take up the optimized solution and performance-wise also feasible.
Whether I should go for
1. Using 'include jsp'
2. using 'taglib'
3. creating a seperate utility class with the required methods and 'import' it in the JSP pages.
Kindly reply ASAP.
Thanks in advance.
Regards.

I would suggest you should go for user defined tags.
This would ensure that the business functionality is isolated from your web objects and it would be modular to maintain.
Using simple classes will add java code to your JSP pages, which makes them less readable.
Apart from that implicit object creation by the Servlet/JSP engine(which are instantiating and garbage collecting the taglib objects) will be more efficient.
Hope this helps
regards
Ravi

Passing parameters to included JSP files using JSF

I have included JSP, which I use in many other JSP files. I want to display message in this included JSP which depends on the information in JSP files which include this JSP. How can I do this without using scriptlets?

I have one included page in one jsp page(mother page). I have included it by jsp:include tag. The included page consists of two inputText. I need to pass the parameters of the mother page together with the parameters in the included page in the backingBean of the mother page. Hope this one is clearer.
The code snippet in the mother page looks like this
<jsp:include page="/pages/ps/sample_rep2.jsp"/>.
In the sample_rep2.jsp, I have two inputText. How can I pass this in the backingBean of the motherpage.
The sample_rep2.jsp is the included page here. The sample_rep2.jsp looks like this:

Use classes in JSP without jsp:useBean

hi
i want to instantiate my own classes within a jsp.
the classes are in web-inf/classes/chat/
there is one main class which is used all over the app, so i use it with the jsp:useBean and scope on application.
The messages are saved in objects of the class Message. now i want to use this class in my JSP without useBean.
Is this possible without extra setting the classpath?!
I get the error because the interpreter searchs in a package from tomcat itself..
Thanks a lot and rgds
Ruven

I think you can use any class in your jsp file without the <jsp:useBean>, this implies that you have to declare your class in the ordinary way i.e
<% MyClass c = new MyClass() ;
//other code
%>
the important thing is to use the page directive's import attribute i.e include this line in your jsp page
<%@ page import="mypackage.inner.MyClass" %> the web containers when sees this line will assume that you have the following directory structure in your web application ( /mywebapps/web-inf/classes/mypackage.inner/* )
I hope this helps

How to call a class file in a jsp without deploying anything in j2ee

Hi,
I am new in J2EE. I have some jsps, which I configured using web.properties(documentroot=c:/jsp/). I am able to get
those pages by the web browser. I have some import statements in some jsps, now I
am trying to access those page but it is failing, it says
org.apache.jasper.JasperException: Unable to compile class for
JSPD:\j2sdkee1.3\repository\pradip\web\_0002fLogin_0002ejspLogin_jsp_0.java:1:
Class com.gui.UPMGuiGlobalConstants not found in import.
import com.gui.UPMGuiGlobalConstants;
Actually I have not deployed any class file or jsps.. Now my question is can I access
these jsps without deploying anything, like can I put my .jar file in any j2ee
directory(like lib or anywhere else, I already tried after putting in /lib) and restart the
j2ee and use it. So how can I call a class file from a jsp without any kind of
deployment?
Please send me the reply as soon as possible.
Regds,
Pradip

After you put the jar containing the class to import into the WEB-INF/lib directory, you still need to include it in the jsp.
Putting the jar into the lib dir, will make it available to the vm, but as in any other java class, you still need to import it into the class, that the jsp will be compiled into.
And you do that by putting
<%@page import="com.gui.UPMGuiGlobalConstants" %>somewhere near the top of your jsp. (well you don't need to put it there, but it good style ;)
That should do it.

Get site id in WCS jsp without using ics.SQL

Hi,
Is there a way i can get siteId of my current site in JSP without using ics.SQL tags and getting it from publication table
We are trying to implemet a lucene search for loading assets present in current site only.
Thanks in advance for your help.

Use the below code to get it.

How to access a variable from a dynamically included JSP page

I have a jsp (say main.jsp) using the following in its code :
<jsp:include page="menu.jsp" flush="true" />
I have a variable in menu.jsp which I would like to use in my main.jsp.
How do I get the value of the variable defined in menu.jsp ?
I called this variable in menu.jsp, Public, but this didnot help me use the value of that variable in main.jsp
Any help is highly appreciated.. thnks a lot

I do notice the variable var1 has the value populated - in menu.jsp - (from View -->
Source in the browser) but for some reason not able to use it in main.jspI'm not quite sure of the way your jsps are structured from your code snippet but I think there is something to be aware of here that may be part of your problem, namely the difference between the include directive and the include action.
You are currently using the include action, this treats the included resource as a dynamic object - i.e. a request is sent to that resource and the resulting response is included in your page. So when you think of what there is no java variable actually included - you'll just get the resulting HTML that is generated by menu.jsp
The include directive, as in <%@include file=�menu.jsp � %>, on the other hand treats the resource as a static object. This means the actual bytes in the included resource are inserted into the including jsp and then the result of that is compiled and processed, effectively you are cutting and pasting the menu.jsp into your calling jsp. In this case the variable would be available to the calling jsp.
However this approach does bring other difficulties that may break your current code, you'll just have to try it and see what happens.
Hope that's relevant to your problem,
Matt

Custom tag in included JSP page cause exception (WLS 5.1 SP 9)

Included JSP files not seeing JavaScript in main JSP file

Hi All,
I have a JSP page that defines a JavaScript block in it's HEAD block and then includes multiple JSP pages in it's BODY block. Calling a JavaScript function from any of the included JSP pages is met with the following JavaScript error:
JavaScript Error: [unknown origin]:
showBatchDetail is not defined.
I'm not sure what is wrong here since the JSP is generating on the server side and everything is fine by the time it gets to the client side. The entire client side file should be seeing the JavaScript block that was included in the main file.
Any help here would be much appreciated.
Steph.
Some barebones code appears below:
Main.jsp
<HTML>
<HEAD>
<TITLE>UNIT INFO</TITLE>
<SCRIPT LANGUAGE="JavaScript">
function showBatchDetail(batchKey)
var url = "/pditools/html/SfmReports/ShowBatchDetail.jsp"
+ "?batchKey=" + batchKey;
document.location = url;
</SCRIPT>
</HEAD>
<BODY>
<%@include file="ShowBatchSummary.jsp"%>
<%@include file="ShowUnitDefects.jsp"%>
<%@include file="ShowUnitHistory.jsp"%>
</BODY>
</HTML>
ShowBatchSummary.jsp
<TABLE>
<TR>
<TD>
BATCH SUMMARY
<A TARGET="_blank" HREF="JavaScript:showBatchDetail(1000);">(Batch Detail)</A>
</TD>
</TR>
<TR>
Show some data ...
</TR>
</TABLE>

The problem is not about include but about link use
----ShowBatchSummary.jsp----
<TABLE>
<TR>
<TD>
BATCH SUMMARY
<A TARGET="_blank" HREF="#" onclick="JavaScript:showBatchDetail(1000);">(Batch Detail)</A>
</TD>
</TR>
<TR>
Show some data ...
</TR>
</TABLE>
-------end of ShowBatchSummary.jsp--------

How we can use jsf tags in included jsp enclosed in subview tags

Hello everybody,
I am developing web app by using jsf. I am including a jsp page "header.jsp" into another jsp page "main.jsp". The header.jsp page is enclosed in jsf subview tag on main.jsp page. The header.jsp contains some static html code and some jsf tags like "outputText". When i added tag library url in header.jsp then my app was not even not initiating and i was getting following exception
ERROR [UIComponentTag] Faces context not found. getResponseWriter will fail. Check if the FacesServlet has been initialized at all in your web.xml.
16:22:16,890 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at javax.faces.webapp.UIComponentTag.setupResponseWriter(UIComponentTag.java:929)
at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:310)
....Now i removed jsf tag library url from included jsp "header.jsp" so now my app is running but only static html data is being displayed but the value in the jsf tag "outputText" is not being printed in the browser
kindly help me. i would be very thankful....

Your question has nothing to do with Sun Java System Directory Server.

Include external html trough code in a custom tag

Hi,
I have a custom tag. The component class (say MyComponentUI) for my custom component extends UIComponentBase.
I want to include an external html page, which url is formed using the content of an attribute of my tag (for example, the "value" attribute), through the MyComponentUI code.
Can anyone give me some help ?
Pietro

That's actually the same result as you get with a normal include - The method I suggested is a dynamic include similar to the <jsp:include> tag, not the <%@ include %> tag.
When you use a dynamic include, the included page is compiled and 'invoked' as serarately, and the result is what gets included, not the actual source. To get the behaviour you want would require an include directive (the <%@ include %> tag) which I don't think has an equivalence you can use inside a custom tag.
What you can do is pass attributes from the tag class like this:
pageContext.setAttribute(<name>, <object>, pageContext.REQUEST_SCOPE);
and then remove them after the include using pageContext.removeAttribute.
I'm not certain, but this implies that if you declare your variables with a <jsp:usebean> tag with request scope, instead of normal Java variable declarations, you should be able to use them in the page included by the custom tag.
*** in the jsp ***
<jsp:useBean id="myVar" scope="request" class="java.lang.String" />
<% myVar = "Something"; %>
// Now call the tag which uses the pageContext.include() mehtod.
*** end ***
*** in the include ***
<jsp:useBean id="myVar" scope="request" class="java.lang.String" />
<%= myVar + " something else" %>
*** end ***
Let me know if it works.

Proc*C/C++ suport for include files without .h extensions

We have written code C++ code which is Standard C++ ver 5.0 compilant. In this version of C++ compiler the files are without .h extensions. For example <iostream.h> is now to be reffered as <iostream>. We are facing problems in compiling this code with PCC compiler
Sample Code:
File test1.h
#ifndef TEST1H
#define TEST1H
#include<iostream>
#include<list>
class test
private:
int i;
public:
int k;
#endif
File test1.pc
#include <iostream>
#include<test1.h>
int main()
int i;
std::cout << "Enter a value :";
std::cin >> i;
std::cout << std::endl;
return 0;
When this code is compiled with Code=cpp CPP_SUFFIX=cpp PARSE=PARTIAL options we get the following errors
Pro*C/C++: Release 8.1.5.0.0 - Production on Fri Feb 1 12:46:00 2002

Error at line 4, column 9 in file test1.h
#include<list>

I guess so PCC compiler does not identify include files without .h extension.

Do you have the SUNWhea package on your system? This package contains the headers you seem to be missing. It's on the Solaris 8 CDROM 2 of 2. If you don't know how to add packages from the CDROM, look up "Adding and Removing Software After Installing Solaris 8" in the "Solaris 8 Advanced Installation Guide" on docs.sun.com.

Select with One-to-Many and Many-to-One without repeating

Hi
I have a customer who needs a report two sides left and right, but allowing for One-to-Many and Many-to-One relationships in the one report.
A little background:-
This has do do with listings on land and buildings.
One building can be built on a few pieces of land.
Similarly, there can be several buildings on one piece of land.
What is required is a listing of buildings on the left, land on the right, but without repeating the "single line entries" either left or right.
For example Building1 is on Land1 and Land2, and Building2 and Building3 are built on Land3.
We need:-
Building1 Land1
________Land2
Building2 Land3
Building3______
The ___ just used for spacing so you get the idea ;)
Essentially - a "break by" on columns on the left and right.
The Buildings and Land are in different tables, with a link table - one row for each link.
Any ideas?
Thanks
Mike

To jitu.jk - first, this is not in SQL*Plus - its a report in APEX - second, I see no way to break on the left and the right in the same select.
Maybe there is a way.
To Etbin
This is a very inovative solution - I've tried it out and the result is:-
BUILDING LAND
_____Land 4
_____Land 3
_____Land 5
Building 2 Land 4
Building 3 Land 1
_____Land 4
Building 4 Land 4
Building 5 Land 3
_____Land 4
(The underscores I put in for spacing - not perfect but you get the idea - hard whe you write the reply in a fixed space font and it's displayed in the forum in variable space font!! ;)
9 rows selected.
This is not quite the desired result - in your list of associations, we have Building1 associated with Land 3,4, and 5.
So for Building 1 we should have:-
Building 1 Land 3
________Land 4
________Land 5..........
But your result doesn't include Building 1 at all.
The other requirement is that no building or land is ever repeated - so I came up with the concept of "groups".
Starting with one building - I find all pieces of land that are associated - listing them on the right (without repeating the building.
I then find any other buildings asociated with any of the land records that the first building was associated with.
These are listed on the left - without repeating the land records on the right.
This group is given a unique identifier of the minimum association ID (my associations have ID's).
This all done, I use the unique ID as a break column ans summarise additional columns (area, value etc) below each group.
Because of the summaries - adding area and value etc, I can't have any building or land duplicated as I would then "double count" the area, value etc.
Maybe you method can be made to work with some tweaking.
Very clever indeed - forums need great answers like this - it keeps us going.
Thanks again
Mike
