<%# page language="java" contentType="text/html; charset=US-ASCII"
pageEncoding="US-ASCII"%>

<body>
<h2>Hi There!</h2>
<br/>
<h3>Date=<%= new Date() %>

</html>
On the line where I am creating Date object, Eclipse is giving error as
Syntax error on token ")", delete this token
My Eclipse version is:
Eclipse Java EE IDE for Web Developers.
Version: Kepler Release
Build id: 20130614-0229
problem got solved when I added jsp-api.jar into build path of the project.

Please help me to fix it?
I recently solved this using the instructions from this site. Assuming you are using Eclipse: Right click on your project, select “Properties” -> “Project Facets” -> “Runtimes” , select your runtime container. Done, rebuild and refresh your project. See the link for screenshots.
Alternatively, I found this other solution as well. The class in question is from jsp-api.jar, so I added it as a provided dependency to my build. In maven this looks like this. Note that a 'provided' scope means not to bundle it in the WAR as it is expected to be provided by the container (e.g. Tomcat)
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.1</version>
<scope>provided</scope>
</dependency>
I am trying to use JSF Facelet template/Facelet template client first time. I am creating template and template client with Netbeans 7.2.1. When I run that created JSF project and call http://localhost:8080/jpaweb/template.xhtml I can see template style, but when I call client template http://localhost:8080/jpaweb/client.xhtml I see plain text without style. Both files are in the same directory and created by Netbeans wizard. Please, help me with this issue.

If you have Netbeans creating JSF project and JSF template and template client will get you this result. I tried in Netbeans 1.7.0 also. Same problem.
Edit: I run page not like http://localhost:8080/jpaweb/client.xhtml but likehttp://localhost:8080/jpaweb/faces/client.xhtml it worked. There is no "faces" directory in my project. Do we have to add "faces" to all JSF links?
Edit 2: I think netbeans auto-configures that all jsf files are kept in faces directory even there is no such directory in my project. And in Project properties -> Frameworks -> JavaServer Faces -> Configuration there is field JSF Servlet URL Pattern with value assigned /faces/*. I think that means one must call jsf files as if it is in faces directory. Trying to force it work as it appears in my project was a mistake :)
Solved. Changed value of Project properties -> Frameworks -> JavaServer Faces -> Configuration -> JSF Servlet URL Pattern from /faces/* to *.xhtml, and that worked OK.
Your client.xhtml content file is not properly composed. Don't include html tags, as JSF doesn't parse anything out from ui:composition tags here.
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="./template.xhtml">
<ui:define name="top">
Welcome, to my website
</ui:define>
<ui:define name="left">
My links
</ui:define>
<ui:define name="content">
This page is created for testing
</ui:define>
</ui:composition>
I tested with your template and it works.
i have a dynamic web application in eclipse using jsf . i created a jsp page with 'new java server faces(jsf) page(xhtml)' template and want to show just a h:inputText but when i run my app in tomcat the inputText doesn't show up .
when i use 'new java server faces(jsf) page(html)' template i wont have any problem but i have to use xhtml in my project .
i'm using eclipse indigo sr2 3.7.2 - myfaces 2.0.14 - tomcat 7.0.29
my jars : commons-beanutils-1.8.3 - commons-codec-1.3 - commons-collections-3.2 - commons-digester-1.8 - commons-logging-1.1.1 - jstl-api-1.2 - jstl-impl-1.2 - myfaces-api-2.0.14 - myfaces-bundle-2.0.14 - myfaces-impl-2.0.14

<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
thanx for your attention
I was working in Netbeans IDE and switched to Eclipse.
I created a simple JSF 2.0 based using wizard in eclipse. The complete file is this.
index.jsp
<%# page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%# taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%# taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<f:view>
<h1>Hi, This is my JSF 2. Applicaiton</h1>
<br />
Click <h:link outcome="UserLogin">here</h:link> to go to login
</f:view>
</body>
</html>
When I deploted this app in tomcat 7.0 server, I am getting the following error message,
org.apache.jasper.JasperException: /index.jsp(14,6) No tag "link" defined in tag library imported with prefix "h"
In my IDE also I can see the
Help appreciated.
The <h:link> was new in JSF 2.0 and didn't exist in JSF 1.x. This error can thus have the following causes:
You've actually JSF 1.x libraries in your /WEB-INF/lib, not JSF 2.0 libraries.
Your faces-config.xml is declared as JSF 1.x instead of JSF 2.0. Ensure that it is declared conform JSF 2.0 spec.
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
A few quick questions:
Where is your JSF library located?
I think you meant more after:In my
IDE also I can see the which leads
into.
Eclipse is usually pretty good
at being able to find your tag
libraries. Is it complaining about
the use of these libraries in your
jsp editor page?
Let us know some more info about your setup first.
I'll throw out the obvious solution: You've lost the reference to your JSF jar(jsf-impl.jar). Including it in your Tomcat lib folder should fix it.
I'm in the middle of this problem too, I would like to find some solution, but I don't manage. As I found you are at the same step like me.
If you use facelets then you are able to see that tag, instead if you use normal "JSF" it gives the error as you mentioned.
You could try this procedure to solve your problem.
Try to understand how to configure facelets on your web app. For example for my webapp files that ends with *.xhtml are processed by facelets engine.
Rename file to *.xhtml.
Prepend this
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
and
<html
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets">
instead of normal html.
Remove any of the directive
<%# taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%# taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
Detailed instructions can be found here: http://wiki.apache.org/myfaces/MigrateFromJspToFacelets
Then you should be able to process h:link.
I have this simple JSP page in Eclipse and the first line in the file is:
Eclipse however, puts a yellow warning icon before this line with the following tooltip message:
Multiple annotations found at this
line:
- Line breakpoint:index.jsp [line: 1]
- Tag (jsp:directive.page) should be an empty-element tag.
Does anyone know why this is?
UPDATE:
This is my full source script. This is basically the template that Eclipse generates for me when I create a new JSP file based on the XHTML template. I only slightly modified the content to make it do something 'use full'.
I'm using Eclipse 3.4 (eclipse-jee-ganymede-SR1-linux-gtk.tar.gz) on Ubuntu 8.10 with the Geronimo 2.1 plug-in (I don't think that matters though). I had this same problem with every version of Eclipse I've used so far (3.0 and up)
<%# page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<jsp:useBean id="datetime" class="java.util.Date" />
<html>
<head>
<title>Hello Geronimo</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div>
<h1>Hello Apache Geronimo!!!</h1>on ${datetime}
</div>
</body>
</html>
It's an oddity of the DOM validation that happens in the editor even for JSP files, reported in bug 248963 for another situation.
It's expected to be resolved in WTP 3.0.4 & Ganymede SR2.
So what eclipse and WTP version are you using ?
Can you check if this is still the case when you add the following line just beneath the initial jsp declaration:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
as mentioned in bug 257258 (also fixed in WTP 3.0.4 & Ganymede SR2): before WTP3.0.4, this doctype was enough to not show your warning:
