in addition i am also using all the jar files in lib and a struts-html.tld. Please...Please help me...!!

Adding commons-beanutils jar to your classpath may resolve the issue.

you did not add input in action mapping ..in struts-config.xml input="/insert.jsp"

try this

< action path="/insert" type="com.cac.struts.InsertAction" 
        name="insertForm" scope="request" validate="false" input="/insert.jsp">

ok

Probably you made entries in web.xml first and later you added the required jars especially commons-beanutils.jar. Simply delete the contents of web.xml and rewrite them.

Please make sure you have included following jars in your project

  1. antlr-2.7.6.jar
  2. commons-beanutils-1.7.0.jar
  3. commons-chain-1.2.jar
  4. commons-collections-3.1.jar
  5. commons-digester-2.0.jar
  6. commons-fileupload-1.2.2.jar
  7. commons-io-2.0.1.jar
  8. commons-lang-2.5.jar
  9. commons-logging-1.1.1.jar
  10. commons-logging-api-1.1.jar
  11. commons-validator-1.3.1.jar
  12. dom4j-1.6.1.jar
  13. hibernate-jpa-2.0-api-1.0.1.Final.jar
  14. hibernate3.jar
  15. javassist-3.12.0.GA.jar
  16. jstl-api-1.2.jar
  17. jstl-impl-1.2.jar
  18. jta-1.1.jar
  19. mysql-connector-java-5.1.17-bin.jar
  20. ognl-3.0.1.jar
  21. slf4j-api-1.6.1.jar
  22. slf4j-log4j12-1.6.2.jar
  23. spring-beans-2.5.6.jar
  24. spring-context-2.5.6.jar
  25. spring-core-2.5.6.jar
  26. spring-test-2.5.6.jar
  27. spring-web-2.5.6.jar
  28. struts2-core-2.2.3.1.jar
  29. xwork-core-2.2.3.1.jar

If still face problem please download following sample project from google code

http://struts-workspace-setup.googlecode.com/svn/trunk/

You missed mapping in web.xml, it should be like this:

<web-app>
    <servlet>
        <servlet-name>one</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>one</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
</web-app>

Also rename struts-config.html to struts-config.xml.
