Hi!
          I had the same problem, and a found the solution in the Tomcat docs: c:Foreach needs that you put your vector object in the pagecontext.
                    <%@ page contentType="text/html; charset=iso-8859-2" import="java.util.Vector" %>
          <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
          <html>
          <body>
              <% Vector v = new Vector();
               v.add("One"); v.add("Two"); v.add("Three"); v.add("Four");
               pageContext.setAttribute("vector", v);
              %>
              <h3>Iterating over a Vector</h3>
              <c:forEach items="${vector}" var="item" >
               <c:out value="${item}" />
              </c:forEach>
          </body>
          </html>
                              Hope it helps.

Weblogic8.1 SP4 support JSTL

i want to that weblogic8.1 is compatible with jsp2.0 feature like EL [Expression Language] and Filter
Regds
Amit Verma

To the question in your title: Yes, but only JSTL 1.0
To the question in your post: No weblogic 8.1sp4 is not JSP 2.0
But since EL works in JSTL 1.0 too you can use EL in all JSTL 1.0 tags
You also can use ExpressionEvaluatorManager to incorparate EL in your own custom tags.

The jstl use error in the weblogic!!

I am attempting to deploy the example petstore in the weblogic8.1.7,but I found a error :when the server handle sidebar.jsp, a exception occurs: can not find the property "local" setter method. I am very attonished in this exception, but there is no exception in the sun application server. Finally, I download the source code about jstl. I trace the tag class which deal with the tag c:set, and found a odd question in the class the target attribute of this tag such as <c:set value="en_US" target="${catalog}" property="locale"/> donot tansfer to the java bean instance which id is catalog,but is directly as a string.Additionally in the web.xml, I had added such as words: <taglib>
<taglib-uri>http://java.sun.com/jstl/core_rt</taglib-uri>
<taglib-location>/WEB-INF/c-rt.tld</taglib-location>
</taglib>
I had been afflicted by this question for serveral days, and sincerely look forward to your solution.

thanks for your reply,but i am sorry that I have deleted tld file from web-inf and remove the tag "taglib" in the web.xml, additionally, I change all jsp file --give the the correct uri to import the taglib <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %> ,finally restart the server, but the result is that the EL syntax is still invalid. I sincerely hope that I can get a help from again.

Hw can i get arabic support in oracleAS using jstl: showing '?????' symbols

Hello All,
I am using OracleAS for portal deployment and portlets UI constructed by using jstl.
i have used spring portlet jstl for the jsp pages.
when i am trying to change the language, it is showing '?????' symbols.
I have used correct unicode. i tested in pluto portal server. when i deployed in oracleAS,
for english not a problem. for arabic it is showing as '????'.
i have used this code to get arabic in pluto. same code i used. i am getting error.
<c:set target="${pageContext.response}" property="characterEncoding" value="UTF-8" />
<fmt:setLocale value="ar" />
<fmt:requestEncoding value="UTF-8" />
i know it is not setting charector encoding.
i tried some other too like:
<head>
<META http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
</head>
and
<%@ page pageEncoding="UTF-8" %>
No improvement. please help me out of this.
how can i get arabic support in oracle AS by using jstl?
Thanks,
Arun

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.

Is there a logic:match equivalent for JSTL?

In a search page I execute a query which returns an array of objects (All objects are of the same object type and are cast to Object[]) and each object has many attributes. I tried using <logic:iterate>, but I was never successful in having it display any results. I believe this had something to do with the entire array being passed via session scope instead of just one record and me not specifying it properly with <logic:iterate>. I was able to successfully use <c:forEach> and it worked right away. I stuck with using that because of its "just works" ability in addition to using a lot of other JSTL code. However, one of the attributes that is being printed out needs to be parsed and is of the form "Yxxx". <logic:match> covers this very nicely, but when I specify it in the below code it is not able to find my variable in any scope.
<c:forEach var="myResults" items="${sessionScope.result}" varStatus="status">
    <logic:match parameter='${myResults}' property='pin' value='Y'>
        <c:out value="Preeti"/>
    </logic:match>
</c:forEach>I have done several google searches, but I haven't found a JSTL equivalent for <logic:match>. If there is one could someone please tell me what it is? In addition, although <logic:match> is great I still need to print out a substring of that attribute. Could someone tell me how to do that? If this is not possible could someone please tell me if its possible to use <logic:iterate> with an array of objects like I was attempting to do initially so that I could use <logic:match> at least?
Thanks to all of you for your time.

Yes you can use the logic:iterate tag. I think you have to specify the type of the exposed variable though. I prefer the forEach loop.
I think you are using the wrong attribute in the logic:match tag. You should be using the "name" attribute rather than "parameter"
Parameter attribute refers you to a request parameter, and I pretty sure you don't want that.
So given the collection of objects in the session attribute "result"
This should loop through them all, and see if they start with the letter 'Y'
<c:forEach var="myResults" items="${sessionScope.result}" varStatus="status">
    <logic:match name='myResults' property='pin' value='Y'>
        <c:out value="Preeti"/>
    </logic:match>
</c:forEach>As for the latter bit, are you using a JSP2 container and JSTL1.1? It would appear so seeing as you are trying to use EL expressions in the logic:match tag.
If so, you could make use of the JSTL function library:
<c:forEach var="myResults" items="${sessionScope.result}" varStatus="status">
   <c:if test='${fn:startsWith(myResults.pin, "Y")}'>
      <c:out value="${fn:substring(myResults.pin, 1, -1)}"/>
    </c:if>
</c:forEach>And I've just spotted a very cool function in there: substringAfter
<c:forEach var="myResults" items="${sessionScope.result}" varStatus="status">
      <c:out value='${fn:substringAfter(myResults.pin, 'Y')}'/>
</c:forEach>Cheers,

Accessing JSTL values from JSP

I've run into a problem I'm not sure has a solution. Could be bad design on my part, or just a poor imagination. If this has been answered previously, please point me to the post.
I am using some JSTL to do a SQL query and displaying the records in a select box:
<sql:query var="aResults" sql="select * from TYPE_STATE_LIST where tslAllowable=1" />
<c:forEach var="oRecord" items="${aResults.rows}">
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
</c:forEach>I want to be able to reset their selection to the value they entered when the form is refreshed, though. I'm trying to figure out how to grab the oRecord value from the JSTL and use it in a JSP IF statement:
<% if( oRecord.tslID==request.getParameter("state") ) { %>
<option selected value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } else { %>
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } %>I thought about using the JSTL <c:choose> tag instead, but then how would I access the previous value with request.getParameter()?
Any suggestions?

${param.state}It's better if you place the sql query into a class rather than display it in the jsp, it's more flexible and programmable.

Calendar in JSTL

Hi ,
I am using JSTL in JSP and there is an If statement which says
if (Calendar.get(Calendar.YEAR)!=2000){
do some thing
I need to know how to write that if condition in JSTL.

Jstl c:if test

I have put a string in my request:
pageContext.getRequest().setAttribute("photoAccountmanager", "SUCCESS");
How can I retrieve the string in jstl? The next statement doesn't work:
<c:if test="${request.photoAccountmanager == 'SUCCESS'}" >
</c:if>

The proper EL way of retrieving from a particular scope is to use the Scope's map (requestScope for requests, sessionScope for sessions, applicationScope for application).
<c:if test="${requestScope.photoAccountmanager == \"SUCCESS\"}">
Note, that as long as there is no fear of having a variable of the same name in a different scope, specifying the scope is not necessary:
<c:if test="${photoAccountmanager == \"SUCCESS\"}">
Also not the escaped double quotes rather than single quotes. Not positive this is necessary, but I think it is the correct way to do it.
Finally, if trouble still persists, try using
<c:if test="${requestScope.photoAccountmanager eq \"SUCCESS\"}">

Using HashMap's ContainsKey() in JSTL

Can we use HashMap's containsKey() in JSTL <c:if > statement
I tried with the sample
<html:select property="Type" multiple = "true" size = "3">
<option value='<c:out value="${key}"/>'
<c:if test="${requestScope.test.containsKey(key)}">
selected
</c:if>
<c:out value="${value}"/></option>
</html:select >
When i executed the above code i encountered JSP Error
Can any one please let me know the correct code

You can't call java methods from JSTL. It uses the EL - not java.
However there is a solution.
You access maps using the square brackets [ ] notation.
ie ${test[key]}
is the same as test.get(key)
try
<c:if test="${ not empty test[key] }"/>
However seeing as you are using the struts tags, doesn't that automatically take care of this for you? Why don't you use the struts tags for the options list as well as the select? Just a thought :-)
Cheers,

Two if condition in JSTL

can I use and in if statement in JSTL, I f I want to change the following code to JSTL , what should I do
if (!(Tassistant.equals("on"))&& (!TassistantStart.equals("dd/mm/yyyy"))&& (!TassistantUntill.equals("dd/mm/yyyy")))
do I have to use ? can I use and to connection then I don't need that much close </c:if>
<c:if test="${found.tassistant!='on'}"> }<c:if test="${found.tassistant!='dd/mm/yyyy'}"> </c:if> </c:if>
Thnak you!

You can just use the same operators in EL.
And in the future, please choose forum carefully. Posting a very simple question at a wrong forum doesn't let you overcome as smart.

Help needed on Servlets and JSTL

Hi
I am using tomcat 5.5 and JDK 1.5. What are the softwares I have to download for compiling servlets and creating JSTL ?. Help needed.
Thanks
IndyaRaja

I tried compling servlet, but it is raising error
that coul not find package javax.servletWhat I did not mention... you need to add those JARs in the Classpath explicitly. You will find them in %TOMCAT_HOME%\common\lib. You atleast need to add servlet-api.jar to your Classpath. :)

Help needed to run JSTL 1.1 in Tomcat 6.0.16

Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below

Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />

Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:

{color:#0000ff}url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>{color}
{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

Can you help me??
And also, is the "pageContext.setAttribute()" method the correct way to select output as i did, or do u know a better one?
Thanks a lot, bye.

Use the brace notation.

Question regarding JSTL and function calls

Hello
I'm quite new to JSTL and I'm having a problem accessing a function when I want to pass argument to that function.
Im using MVC where my M (model.jsp) can be accest from my V (view.jsp) by doing ${model.(parameter/some function) }
in my M I have a couple of getMethods() (example: getThisInfo() ) and som control methods like "isSomethingValid(arg1)"
my question is lets say I want to access my "isSomethingValid(arg1)" and arg1 should be the value of "getThisInfo()" I thought I could do like
${model.somethingValid($model.thisInfo)} but it isnt working I get:
"Unable to parse EL function ${model.somethingValid(model.thisInfo)}"
I know that the syntax above is a mix of scriptlet and JSTL but I dont know how to or if its even possible to achieve this?
Thanks for helping me!
Best Regards/DS

By default, EL can only access getters and setters on objects.
It can not execute general methods on an object.
You can define function libraries that call static methods
You have to write the method as static, and then declare it in a tld.
public boolean checkValid(Model m, Info i){ ...}
and then you could invoke it something like
<%@ taglib uri="myfunctionstaglib" prefix="myfunctions" %>
${myfunctions:checkValid(model, model.thisInfo)}

JSTL 1.0 on Weblogic8.1
