ClassCastException

Hi,
I am trying to query a Xindice database within a .jsp page through the 
use of a Java Bean.  Within Tomcat I am getting 
"java.lang.ClassCastException: 
org.apache.xindice.client.xmldb.embed.DatabaseImpl".  The following code 
is in my Bean:
          String driver = 
"org.apache.xindice.client.xmldb.embed.DatabaseImpl";
          Class c = Class.forName(driver);
          Database database = (Database) c.newInstance();   << Line 
creating the exception
          DatabaseManager.registerDatabase(database);

Any thoughts?

Thanks,
Ben McCann
