Is it possible todeclare primitive variable by using JSTL tag

Hi friends..........
I have to use jstl tags in my project , so i have to know how to declare primitive variables with jstl tag. Is it possible with <c:set > jstl tag........
Hope i get the answer...........
Thanks in advance...............

JSTL variables are attributes in the page, request, session and application scopes.
As such, they can only be objects, because you can't store a primitive value as an attribute.
However you shouldn't need to declare primitive variables. You should hardly need to declare any variables.
JSTL is not a programming language. It is a language to aid the display of a JSP. Therefore most of its attention is geared towards outputting things, with a much lesser concern on setting them.

Use JSTL tags for ATG droplets and beans

Hi,
I am trying to display profile values in a JSON object in jsp.
<dsp:getvalueof var="json" bean="ProfileFormHandler.ProfileJSON"></dsp:getvalueof>
<c:out value="${json}" />
but instead of using dsp tag is there a way for accessing ProfileFormHandler using JSTL tag
Also how can we use droplets in ATG like ForEach using JSTL tags only
<dsp:droplet name="ForEach">
<dsp:param name="array" param="catalogItems.rootCategories"/>
<dsp:param name="elementName" value="categoryItem"/>

I am trying to display profile values in a JSON object in jsp.
<dsp:getvalueof var="json" bean="ProfileFormHandler.ProfileJSON"></dsp:getvalueof>
<c:out value="${json}" />
but instead of using dsp tag is there a way for accessing ProfileFormHandler using JSTL tagIn the <dsp:importbean> use var to give an EL variable name to the component you are importing.You can also set its scope attribute to page, request, session, or application with page scope being the default. You can then access it as a page scoped attribute. So this should do:
<dsp:importbean var="profileFormHandler" bean="/atg/userprofiling/ProfileFormHandler" />
<c:out value="${pageScope.profileFormHandler.ProfileJSON}" />In case you change the scope in importbean you can accordingly use pageScope, requestScope, sessionScope or applicationScope.
Also how can we use droplets in ATG like ForEach using JSTL tags only
<dsp:droplet name="ForEach">
<dsp:param name="array" param="catalogItems.rootCategories"/>
<dsp:param name="elementName" value="categoryItem"/>Any ATG droplet is nothing but a servlet which is also a Nucleus component. So essentially you want to call a servlet from JSTL which as such shouldn't be done in a well written script-less JSP. You can probably try to use the droplet as a bean and use JSTL on top of it but since ATG droplets also have different types of parameters like input, output and open so you will have to specially handle those.

Posting huge data on to JSP page using JSTL tags

Hi,
I have one application where I have to post huge data (approximately 2000 rows of data) into JSP page. I am using JSTL tags and running on Tomcat 5.
It is taking almost 20 to 25 seconds to load the entire page.
Is it the optimal time to load or it could be improved?
Please let me know.
Thanks,
--Subbu.

Hi Evnafets,
Thank you for the response.
Here are the tasks I am doing to display the data on JSP.
0. We are running on Tomcat 5 and the memory size is 1024MB (1GB).
1. Getting the data - I am not performing any database queries. The data is stored in the static cache memory. So the server side response is so quick - less than a milli second.
2. Using Java beans to pass data to the presentation layer (JSP).
3. 10 'if' conditions and 2 'for' loops and 2 'choose' statements are being used in the JSP page while displaying the data.
4. Along with the above, there are 4 javascript files are being used.
5. The jsp file size after rendering the data, is aprox. 160 kb
Hope this information helps you to understand the problem.
Thanks,
--Subbu.

Problem in using JSTL tag libs

Hi there,
I am trying to use JSTL tag libs in my web app, but i get the following error message:
org.apache.jasper.JasperException: /index.jsp(22,0) According to TLD or attribute directive in tag file, attribute test does not accept any expressions
as it might be clear i am using Tomcat and line 22 of the code for index.jsp is:
<c:if test="${user.role > 0 }">
Please help my identify whats wrong in there. I suspect that it is because of my web.xml file, but i am not sure.

Not able to use JSTL tags

Hi
I am not able to use any tag in jstl. I have tried c:out,c:forEach,c:if etc. I have done mapping in the web.xml for the c.tld. I have tried the same code in eclipse and IBM websphere and Rational also but i am getting the error
Custom tag attribute test cannot be runtime expression. value: "[${userType eq 'member'}]"
i thought that it may be something related to configuratioin problem but now I am working in IBM rational and it has support for JSP 2.0. one thing more, I read in the HeadFirst servlets and JSP book that we needn't do any mapping for tlds etc in jsp 2.0. So please elaborate more and tell me the exact reason for my problem.
I will really appreciate the guy who answers me as soon as possible.
my persona email id is [email protected]
Thanking in advance!

Custom tag attribute test cannot be runtime expression. value: "[${userType eq 'member'}]"You say you are using a JSP2.0 container?
This message usually indicates that you are using JSTL1.0 with a JSP2.0 container.
Make sure you are using JSTL1.1 (seperate download), and are importing it with the correct URI
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
(note the subtle addition of the /jsp in there to distinguish it from JSTL1.0)
As has been said, remove all those tlds and entries in web.xml.
All of the tld can be found in the META-INF directory of standard.jar.
Your web container should find them all there, provided you use the "standard URI"

Problem using JSTL tag libraries with OC4J 9.0.3

I'm using the JSTL tag libraries with OC4J 9.0.3. I'm using JDeveloper10.1.2. I put the fmt.tld and c.tld in the WEB-INF directory and I'm adding the jstl.jar and standard.jar library to the EAR file. Both tlds have:

User,
You should configure the taglibs using the project->libraries option in JDev. If that doesn't help, try adding the taglib URI mappings to web.xml as detailed [url http://forum.java.sun.com/thread.jspa?threadID=650000&messageID=3823804]here

Ok, I did a bit more experimenting, and web searching, and found you are the victim of the UTF-8 BOM bug.
Basically the java UTF-8 reader does not recognise a BOM at the start of a UTF-8 stream, and it has to be discarded manually.
For details: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4508058
Here is a 'fixed' JSP for you.

How to access variables indirectly using JSTL

Hi,
I have a variable called titleInsert pointing to a session variable someSessionVariable. The jsp has access to titleInsert but would like to output the value of someSessionVariable which is pointed to by tilesInsert.
If I have something like
<c:out value="${titleInsert}"/>
the name of the session variable is being displayed but not the value.
I tried something like
<c:out value="$${titleInsert}"/> and
<c:out value="${${titleInsert}}"/> and both resulted in JSP exceptions.
Is there a way to display the value of someSessionVariable?
Help appreicated,
Kumar

You use the implicit variable sessionScope, and the square brackets notation.
<c:out value="${sessionScope[titleInsert]}"/>Cheers,

Using JSTL tag in a custom tag

Hello,
I have created a custom tag, and I want to call the c:import tag inside the doTag method of my custom tag. Is this possible ?
Thanks in advance for any answer!

Hello,

Not in tag classes. Possible if you implement custom tags using [url http://www.onjava.com/pub/a/onjava/2004/05/12/jsp2part4.html]tag files

Could I use jstl tag in the JSP page of Creator 2 final release?

I have a JSP page used to work well in Creator 2EA2. The page
has the following code snippets:
<c:forEach items="${SessionBean1.webQuery1.details}" var="item">
                                                    <tr>
                                                        <td class="detailKey">
                                                            <c:out value="${item.key}"/>
                                                        </td>
                                                        <td class="detailValue">
                                                            <c:out value="${item.value}"/>
                                                        </td>
                                                    </tr>
                                                </c:forEach>
...Basically, it generates a table columns.
After migrating to Creator2 final release, a fatal exception is thrown
when the page is launched :
Description: An unhandled exception occurred during the execution of the web application. Please review the following stack trace for more information regarding the error.

There is something strange in the HTML for you posedt, so I cannot clearly see what you are trying to do in your JSP page. But either of the following kinds of usage would cause this kind of error:
    <h:dropDown ... items="<%= ...some Java expression ...>"/>or
    <h:dropDown ... items="${...some JSP EL expression...}"/>This is because JSF component tags allow neither Java runtime expressions nor JSP EL expressions (at least in JSF 1.1, which is what Creator 2 supports). The answer is to use a JSF EL expression instead, like this:
    <h:dropDown ... items="#{... some EL expression}"/>Craig

Fetch value from USER_SEQUENCES using JSTL tag

<sql:query var="seq_range">
select MAX_VALUE, MIN_VALUE from USER_SEQUENCES
where SEQUENCE_NAME = 'HTS_SEQ_ID_GRC11'
</sql:query>
<c:out value="***${seq_range.rows[0].MAX_VALUE}"/>
But it is showing null....
Is there is any other tag to get vlue from sequences

I assume that you simply want the Form Id to happen at the begining.
The key here is to use the varStatus to track your way during the iteration, so look up varStatus as part of the forEach for the details about how this works.
<c:forEach items="${list}" var="bean" varStatus="status">
    <c:if test="${status.index == 0}">
        <p>Form Id: ${bean.id}</p>
    </c:if>
    <p>Transaction: ${bean.transaction} Date: ${bean.date}</p>
<c:/forEach>
