I am getting this message when I run my web application. It builds fine but during deploying, It fails everytime by this error: 

SEVERE: The web application registered the JDBC driver[oracle.jdbc.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

Any help appreciated.

FYI: My pom.xml is:

      <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.1.26</version>
      </dependency>
      <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.1.26</version>
      </dependency>        

    <dependency>
        <groupId>org.primefaces.extensions</groupId>
        <artifactId>primefaces-extensions</artifactId>
        <version>1.0.0.RC1</version>
    </dependency>
    <dependency>
        <groupId>org.primefaces</groupId>
        <artifactId>primefaces</artifactId>
        <version>4.0.RC1</version>
    </dependency>

Following is full list of errors I have got in Tomcat log:

    You can't possibly see that error during deployment because it is generated during undeployment. Also, it won't stop anything working. What, exactly, is the problem you are trying to solve? – Mark Thomas Nov 11 '13 at 19:29

    Maybe this [link1](http://stackoverflow.com/questions/3320400/to-prevent-a-memory-leak-the-jdbc-driver-has-been-forcibly-unregistered) and this [link2](http://stackoverflow.com/questions/2604630/tomcat-fails-to-start-because-of-jdbc-driver-loading) can help you – danRod Nov 11 '13 at 19:31

    I am working on some project, and I was using primefaces 3.5 but wanted to upgrade it to 4.0. I have added the jar files but same project which was working fine on 3.5 with tomcat is now not deploying on it, So that is my concern at this moment. If You want I can give full error log which I got during deployment.. – user2959092 Nov 11 '13 at 19:58
  • Are you keeping the same tomcat 7? Or are you using an upgraded version (from 6 to 7)? – danRod Nov 11 '13 at 20:03
  • No I am Keeping the same Tomcat 7.0.41 – user2959092 Nov 11 '13 at 20:03
  • The error message is about JDBC library, not about PrimeFaces. Looks like something is wrong in your tomcat installation or you have removed another library in your pom. – Luiggi Mendoza Nov 11 '13 at 20:25
  • I didn't remove anything from Pom file. And, I just changed the versions of Primefaces and Primefaces extension from 3.5 to 4.0.RC1 and also jsf-api and jsf-impl to 2.1.3 – user2959092 Nov 11 '13 at 20:35
  • Weird, I have the same setup (sans the extensions) and it deploys just fine. Are you sure you don't have duplicate libraries deployed in your web application? This smells like an old version of Primefaces and PF 4.0 both existing in the application at once. BTW: you're linking to a release candidate version, use version 4.0 to link to the final version. – Gimby Nov 11 '13 at 21:21
  • I tried 4.0 too, I have double checked and In dependencies I have only Primefaces 4.0 and primefaces extension 1.0.0 that's it. If there is some other jars which are related to it then I am not sure But Yes, Its Kind of weired Its not deploying stuffs and Same stuffs is getting deployed if I use Primefaces 3.5 and Primeface extension 0.6.3. So It means, There is no issue in code which I have but may be smth I am missing here .. – user2959092 Nov 11 '13 at 21:34
