title: Multiple applications having c3p0 configuration gives warning
body: <p>Hi<br>
  I have two web application under one tomcat. Both are using hibernate 3.2.1 and c3p0 0.9.1.2. While the second application gets deployed, I always get the following warning message.<br>
  Tomcat: <strong>apache-tomcat-6.0.28</strong></p>
  
  <blockquote>
    <p>WARN 2010-11-06 19:04:37,270 A C3P0Registry mbean is already registered. This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources.</p>
  </blockquote>
  
  <p>Please help in this regard.</p>
  
  <p>Thanks in advance<br>
