JSF tags not showing

I am new to JSF, but my JSF tags do not appear in the xhtml file, I tried all possible solutions, but the problem is not solved.

my web.xml

<?xml version="1.0" encoding="UTF-8"?> <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"> <display-name>JSFProject</display-name> <welcome-file-list> <welcome-file>JSFProject/index.html</welcome-file> <welcome-file>JSFProject/index.htm</welcome-file> <welcome-file>JSFProject/index.jsp</welcome-file> <welcome-file>JSFProject/default.html</welcome-file> <welcome-file>JSFProject/default.htm</welcome-file> <welcome-file>JSFProject/default.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping> </web-app>

my example.xhtml

 <?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Example</title> </head> <body> <h:form> Some random data: <h:inputText/><br/> <!-- Textfield ignored --> Some other data: <h:inputText/><br/> <!-- Textfield ignored --> </h:form> </body> </html>

I spent 3 days figuring out the problem, any help would be appreciated

Symbols for JSF components that are not parsed at all indicate that FacesServlet not running. This will happen when the request URL does not match the url-pattern FacesServlet , as defined in web.xml . This would mean that the actual url-pattern for the FacesServlet not *.xhtml at all. You study and edit the correct web.xml , which do you think you are? Is web.xml right deployed using webapp in servletcontainer?

I had the same problem, I fixed it by updating below: Martin mentioned above. Thank you

web.xml

 <context-param> <param-name>javax.faces.DEFAULT_SUFFIX</param-name> <param-value>.xhtml</param-value> </context-param> <context-param> <param-name>javax.faces.application.CONFIG_FILES</param-name> <param-value>/WEB-INF/faces-config.xml</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.faces</url-pattern> </servlet-mapping>

faces-config.xml

 <application> <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> </application>

Try:

 <?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Example</title> </head> <body> <f:view> <h:form> Some random data: <h:inputText/><br/> <!-- Textfield ignored --> Some other data: <h:inputText/><br/> <!-- Textfield ignored --> </h:form> </f:view> </body> </html>

I have included the JSF tag <f:view>

Man, you did not set the javax.faces.DEFAULT_SUFFIX context javax.faces.DEFAULT_SUFFIX . The default value for jsf is jsp , so jsf will look for example.jsp instead of example.xhtml . Basically, jsf replaces the extension of the resource requested with javax.faces.DEFAULT_SUFFIX .

Use the following and it will work:

 <context-param> <param-name>javax.faces.DEFAULT_SUFFIX</param-name> <param-value>.xhtml</param-value> </context-param>

Do you have face-config.xml that declares Facelets as a view handler?

 <?xml version="1.0"?> <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_1_2.xsd" version="1.2"> <application> <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> </application> </faces-config>

Remember the javax.faces.DEFAULT_SUFFIX parameter, which must be set to .xhtml, as described above.

Add the following to your web-inf / lib file:

JSF-api-2.0.9.jar JSF-Facelets-1.1.14.jar JSF-osusch-2.0.4-b09.jar JSTL-1.2.jar

without jsf-facelets * .jar, you cannot display the jsf view.

And, following the example of your web.xml:

  <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/jsf/*</url-pattern> <url-pattern>*.xhtml</url-pattern> </servlet-mapping>

Without more than two url templates, tomcat will not be able to display the .xhtml file correctly.

And, faces-config.xml:

 <?xml version="1.0" encoding="UTF-8"?> <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"> </faces-config>
