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

How to call the form bean value on jsp withthe help of jstl tag

hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstl

You use the jstl core:if or core:choose combined with the EL:
<c:if test="${empty users.userListForm}">
NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

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.

Is the jstl tag libray loaded in the appsserver?
Can you use jdbc connection like
DataSource ds = ic.lookup("java:comp/env/jdbc/myDB");
Connection con = ds.getConnection();
DataSource ds = (DataSource) org.apache.derby.jdbc.ClientDataSource()
ds.setPort(1521);
ds.setHost("localhost");
ds.setUser("APP")
ds.setPassword("APP");
Connection con = ds.getConnection();

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"%>

<title>Insert title here</title>
</head>
<body>
<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>
          <th>Type</th>
     </tr>
     <tr>
          <c:foreach items="${requestScope.users}" var="user">
               <td><c:out value="${user.id}" /></td>
               <td><c:out value="${user.name}" /></td>
               <td><c:out value="${user.email}" /></td>
               <td><c:out value="${user.type}" /></td>
          </c:foreach>
     </tr>
</table>This i get as result page...
ID      Name      e-Mail      TypeFinally, this is the code of showUsers.jsp...

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"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"

          <servlet-name>MyServlet</servlet-name>
          <servlet-class>src.MyServlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>MyServlet</servlet-name>
          <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?

Problem trying to run compile jsp containing JSTL tags

Hi,
I am facing a problem regarding compiling jsp containing JSTL tags.
Can anybody help me out?

Yes it is giving an error when i try to compile the jsp.
And it's giving error on the include of the taglib in the jsp as
C:\dev\ppdev\DOMA\jspcompile\WEB-INF\jstl\c-rt.tld" is an invalid archive file!
Actually we are not using th default entry for taglib. Instead we have made an entry in the web.xml. Like this
<taglib>
<taglib-uri>/WEB-INF/c.tld</taglib-uri>
<taglib-location>/WEB-INF/jstl/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/c-rt.tld</taglib-uri>
<taglib-location>/WEB-INF/jstl/c-rt.tld</taglib-location>
</taglib>
And using this uri in the jsp page like this
<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/c-rt.tld" prefix="c_rt" %>
And when we try to compie the jsp its giving the error.
C:\dev\ppdev\DOMA\jspcompile\WEB-INF\jstl\c-rt.tld" is an invalid archive file!
I would appreciate your help and update me if any more information is required.

Jstl tags to display System date.

Hi there,
Please let me know how to how to display system date on jsp page using jstl.
I dont know much about jstl, and i was till now using java code in jsp instead of jstl.
Since using java in jsp is considered a bad programing these days, I dont want to use java
to display the date.
Can anyone help me switch to jstl tags.
Please help me with the date issue.

[This will help you|http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/index.html] learn what JSTL tags are available. Once you get that it should be relatively easy to figure out what you nee. If you have questions on a particular tag then a [Google search almost always|http://www.google.com/search?q=jstl+fmt%3AformatDate] brings up example usage.

JSP Compilation Problems With JSTL tags

My JSP worked well when I used JSP expressions, scriptlets, .... I tried to use JSTL instead and encountered some compilation problems. I am unable to see my mistakes and need help:
Problme #1:
int offset = 0;
try
   <c:set var="offset" value="${requestScope.offset}" />
catch ( Exception e )
    // do nothing
}The above code has two compilation errors:
Generated servlet error:
[javac] Compiling 1 source file
illegal start of expression
<c:set var="offset" value="${requestScope.offset}" />
^
Generated servlet error:
';' expected
<c:set var="offset" value="${requestScope.offset}" />
^
Problem #2:
<c:set var="threadBean" value="${requestScope.ThreadBean}" />
int threadID_int = ParamUtil.getParameterInt( request, "thread" );
<c:if test="${threadBean.threadID} != threadID_int">
    throw new AssertionException( "The two threadID are not the same." );
</c:if>Generated servlet error:
illegal start of expression
<c:if test="${threadBean.threadID != threadID_int}">
^

I have deleted the Java code around the JSTL tags. Now, what is wrong with this <c:if test=" ... "> tag? It seems that I have problems to get JSTL tags right.

<c:if test="${attachBean.attachMimeType.startsWith('image/')}">

Comparision btw Struts and JSTL tags

Hi,
Is there any article or helpful information that any body have come across that have good comparision between struts and JSTL tags? I am trying to find similar JSTL tags to my struts application.
Any help in this regard is appreciated.
Thanks,
-jon

You can't use JSTL to replace struts completely. The struts tags and the JSTL tags have some overlap in the logic, control flow and formatting bits, but there is a lot that struts does that JSTL doesn't (the input controls).
Struts-el was a bridge between Struts and JSTL for JSP1.2 containers.
It has a very limited use nowadays. Most applications should be being written in J2EE1.4 (Servlet 2.4/JSP2.0), and thus the requirement for the struts-el tags is not there - the container understands EL without special tags required.
As I said before you should only use Struts-EL if
- You are stuck with a J2EE1.3 (Servlet2.3/JSP1.2) container
- You want to use EL with struts.
For myself, I prefer using the EL expression like ${expr} rather than older <%= expr %>, but it comes down to personal preference.

JSTL tags where executing?

Hello,
I just started using JSTL tags and I would like to know where they are executed, is it at the browser of the user or at the server? The reason I am asking is that I need to know, if the user do not have Java platform install, he will still have the fuctionality of JSTL tags?
I cannot find this information in any documentation so any help would be great.

good issue.
i also have some doubt about JSTL.
when use write
<form:form name="myForm" command name="Email">
<table>
   <tr>
        <td>
                 <c:out value="${Email.fromId}"/>
        </td>
   </tr>
</table>
</form:form>see if fromId is private member of Email class then also we able use it in the JSP page. according to Java concept we can use private variable with the class scope only.
so how come we are able to use that one in JSP page.
Thanks,
-Ravi.
