taglib not working
I am trying to get my first taglib to work in my webapps:
Tomcat 5.5\webapps\myfirst
I keep getting error message when I pull up my servlet that is calling my jsp:
org.apache.jasper.JasperException:
The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
Here is my jsp:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<c:forEach var="city" items="${requestScope.city}">
......
</c:forEach>
</table>
</body>
</html>
I am not sure if I need to add some sort of taglib info in my web.xml or what I need to do to get taglib to work?
You require extra library files over the standard Tomcat ones to run the JSTL.
Specifically standard.jar and jstl.jar need to be in the WEB-INF/lib directory.
You can get them from here:
http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html
http://jakarta.apache.org/site/downloads/downloads_taglibs-standard.cgi
In web.xml add these entries ...
<taglib>
<taglib-uri>c.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
make sure that you have extracted the tlds in the mentioned path.
In your jsp add this line
<%@ taglib uri="c.tld" prefix="c" %>
You can download the tag libraries from the links evnafets has mentioned.

No that's not required. Just specify the uri attribute in your jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
And place standard.jar and jstl.jar in WEB-INF/lib. The container will auto discover the tag library and the tlds at runtime. The uri resolves to the uri attribute of the tag library tld.
ram.
Thanks I downloaded what you suggested in my web-lib (Tomcat 5.5\webapps\test\WEB-INF), the taglib part I think is working but now I get just the variables showing on the jsp but no errors on the page:
Customer List Id First Name Last Name Address
${customer.id} ${customer.firstName} ${customer.lastName} ${customer.address}
I tried this:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
and this:
<%@ taglib uri="c.tld" prefix="c" %>
It should show the customer values but for some reason it not showing.
hi
do one thing you change in web.xml as follows u should mention the version
u just do one thing copy the following and paste in web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<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" version="2.4">
i hope it will work because the expression language will work this version effectively

It still gives the same output. It doenst seem to want to show the variable values.
Here is my web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<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" version="2.4">
<description>Configuration file for website</description>
<servlet>
<servlet-name>Tester</servlet-name>
<servlet-class>Tester</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Tester</servlet-name>
<url-pattern>/Tester.soccer</url-pattern>
</servlet-mapping>
<servlet>

</web-app>
My taglib line:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I'll assume standard.jar and jstl.jar are in place, that means in your WEB-INF/lib directory. Try two things, if you're using Tomcat 5.5.x:
change this:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
into this
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
an then, (don't laugh I'm serious) change the string "version=2.4" to the beggining of web-app tag. This strange exchange, saved me from this very same problem. I must admit I could not believe it ( i read this solution on this forum) untill I saw it worked.
So, it would be like this: (version first) . Just give it a try and you'll see.
<web-app version="2.4" 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">
hi Mr.oaklandar
You just send what is your output .
in your web.xml where is
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
you should specify the location of the tld file either above or with out mentioning in
web.xml as follows
<@taglib uri="/WEB-INF/c.tld" prefix="core">
try this dont forget to mention the version in web.xml
try this it may help u
let me know what are getting the out pue
write clearly i may help u

Thanks it now works great.
Do I have to load extra library files for every web app where I have to put library files in each WEB-INF for each web project?
For example if I have it now working in my test webapp I would have to do the same with anotherProject by loading all the library files in the anotherProject WEB-INF folder?
C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\test\WEB-INF
C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\anotherProject\WEB-INF
hi
You can do one thing u can direcly place the jar files in
C:/ProgramFiles/Tomcat5.5/commons/lib
in this one u can place all the jar files which will use to your projects because
these jar files automatically loaded when the server stats
i hope it may help u
Cheers,
