I did not able to find out reason behind it .

2. jsf-impl-2.0.3.jar
3. jstl-1.0.2.jar
4. primefaces-3.4.jar

"My JSP 'index.jsp' starting page"? Please block/ignore/throwaway that tutorial you're reading now. It's only completely confusing you and teaching you bad practices.
As to your list of libraries:
Folloing are the library I included into web-inf/lib
- jsf-api-2.0.3.jar
- jsf-impl-2.0.3.jar
- jstl-1.0.2.jar
- primefaces-3.4.jar
First of all, the JSTL version is wrong. It should be at least JSTL 1.1 or preferably 1.2. The EL (expression language, those ${}
/#{}
) things would otherwise fail to work. Remove jstl-1.0.2.jar and put jstl-1.2.jar in place.
Further it looks okay. It only surprises me that you've more than 2 years old JSF API/impl versions while you've a fairly recent (less than 2 weeks) PrimeFaces version. I'd align those JSF API/impl versions as well to be the latest available. It's currently already at 2.1.13 (note: it's now composed of only one JAR file javax.faces.jar instead of two JAR files).
As to your web.xml
:
<web-app version="2.5" 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-app_2_5.xsd">
This is declared conform Servlet 2.5 spec which is over 6 years old already. Are you sure that you're running such an outdated container? Given the presence of the JSF and JSTL libraries, I assume that you're using Tomcat. The current Tomcat version, 7.x, exist more than 2 years already and is Servlet 3.0 compatible. You should declare your web.xml
to match the highest supported version of the target container.
<web-app version="3.0" 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-app_3_0.xsd">
Further, those javax.faces.STATE_SAVING_METHOD
and javax.faces.DEFAULT_SUFFIX
entries represent the default values already. Just get rid of them to minimize noise.
As to your login.xhtml
:
<h:Form>
<h:PanelGrid columns="2" cellpadding="2">
Tag names are case sensitive. The <h:Form>
and <h:PanelGrid>
doesn't exist at all. It are <h:form>
and <h:panelGrid>
.
<CENTER>
While not immediately a problem, but this HTML element is deprecated since 1998 in favor of CSS. Also, seeing it in uppercased flavor instead of <center>
, which is very typical for pre-90's HTML style, doesn't give me the impression that you're reading the most recent and right books/tutorials to learn web development. You should assure that your learning resources are up to date.
As to your index.jsp
: this is completely useless. Remove it altogether. Just change your web.xml
from
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
to
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>login.xhtml</welcome-file>
</welcome-file-list>
and this way login.xhtml
will show up as "home page" when you access /
in your webbrowser. Note that you shouldn't and don't need *.jsf
URL pattern anymore.
