FAIL - Application at context path /Hello could not be started

I'm trying to deploy new web application in Tomcat 6.0, but whenever I click on start button, I repeatedly getting FAIL - Application at context path /Hello could not be started. Other deployed application running fine, whenever I click on start button. But why not this application?

web-xml:

 <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">

<servlet>
<servlet-name>j_security_check</servlet-name>
<servlet-class>EmailHander</servlet-class>
</servlet>

<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/fail_login.html</form-error-page>
</form-login-config>
</login-config>
<web-app>

This is what Exception I'm getting in catalina log file:

Jan 23, 2010 6:49:31 PM org.apache.catalina.startup.ContextConfig applicationWebConfig

The java version used by Tomcat must be correct. The version that is 8.5 uses 1.8 java.

1st Reason could be the ending tag of your application's web.xml file which could not have been closed properly.

web.xml might be ending with <web-app>, but must end with </web-app>

2nd Reason which worked in my case could be the lib folder of your tomcat must contain the supporting jar file of your database.

ojdbc on case of Oracle or sqljdbc in case of SqlServer

I've had the same problem, was missing a slash in servlet url in web.xml

replace

<servlet-mapping>
    <servlet-name>jsonservice</servlet-name>
    <url-pattern>jsonservice</url-pattern>
</servlet-mapping>

with

<servlet-mapping>
    <servlet-name>jsonservice</servlet-name>
    <url-pattern>/jsonservice</url-pattern>
</servlet-mapping>

You need to close the XML with </web-app>, not with <web-app>.

Your web.xml ends with <web-app>, but must end with </web-app>

Which by the way is almost literally what the exception tells you.

Is EmailHandler really the full name of your servlet class, i.e. it's not in a package like com.something.EmailHandler? It has to be fully-qualified in web.xml.
