You generally don't want a singleton that has instance members, otherwise you might end up with threading issues. Use the ThreadLocal as your repository of information, since you're already doing that. I recommend a method that fetches the variable from the ThreadLocal. That way, you can add logic that checks for null and throws an exception if it's missing... since I assume that the presence of the ThreadLocal data is essential. This way, your error checking won't clutter each of the methods that will actually be /using/ that data. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGfs/09CaO5/Lv0PARAhhxAJ93d6rQMrZozGJy6tg4Wclda5/+zgCfZBAi 5W7N37Izfp4L3jGYlrlCtZ0= =zLdP -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
