title: netbeans IDE: how to delete data source
body: <p>I have a Java Web application that contains a Persistence unit. In this persistence unit I can select an existing data source or create a new data source. When I run this web application on the build in glassfish server, the data source is created on the build in glassfish server. Also a connection pool is created.</p>
  
  <p>I can delete the data source and / or connection pool on the build in glassfish server. This does not delete the data source from the Netbeans IDE. When I run the web application again, the data sources and connection pools are recreated. </p>
  
  <p>How can I delete the data source and connection pools in the netbeans IDE? I can't find this functionality anywhere. </p>
  
  <p>I want to delete the existing data sources and connection pools because I have an problem with a new data source / connection pool. To make sure that there is no mix up happening somewhere between the data sources / connection pools I want to remove the old ones that I am not using anymore. </p>
