    EXCEPTION: Error in use of ManagedConnectionPool

    krake Newbie

      Hello,

      Using jboss 3.0.6 and Oracle 8..1.7.

      I have the datasource working and wrote a small .jsp page and watched the datasource work. I then implemented login authentication with the DatabaseServerLoginModule using the same datasource. This again works fine (only the right users can get in as listed in the DB).

      However, when I use the two together I get the following exception:

      EXCEPTION: Error in use of ManagedConnectionPool: matchManagedConnection failed with subject: null and ConnectionRequestInfo: org.jboss.resource.adapter.jdbc.local.LocalConnectionRequestInfo@552d3bec; - nested throwable: (javax.resource.ResourceException: Error in use of ManagedConnectionPool: matchManagedConnection failed with subject: null and ConnectionRequestInfo: org.jboss.resource.adapter.jdbc.local.LocalConnectionRequestInfo@552d3bec)

      The basic scenario is, user logs into my DB test .jsp page and the error shows up. If I wait a few minutes I can get the conneciton on the .jsp page to work. I have also had the login authentication fail with the same error when I've tried to open a new browser (and force a new authentication) after the test .jsp page has run successfully (not always consistent though).

      Any insite you can give to what might be going wrong would be helpful. I'm mainly wondering if the datasouce pooling is set up right, but it could be a race condition though I don't understand how.

      try {
      c = dataSource.getConnection("xxxx","xxxx");
      if (c == null) {
      %> Connection is null <%
      }
      DatabaseMetaData dbmd = c.getMetaData();
      rs = dbmd.getTables(null,null,"%",null);
      ResultSetMetaData rsmd = rs.getMetaData();
      int columnCount = rsmd.getColumnCount();

      rs.close();
      }
      if (c != null) {
      if (!c.isClosed()) {
      c.close();
      }
      }
      c = null;
      }
