Re: [jetty-users] Unable to find LoginModule class, how to solve it?


I just recently setup a JAAS setup using the same tutorial as you did:

I remember I've had the same exception and I did resolve it by starting from scratch and recreating all config files. So I don't know exactly what my problem was.

However could you please paste:

- All JAAS config files you've created
- The commandline you use to start jetty
- jetty-plus.xml
- web.xml

It's crucial that you don't have any typos in the loginModuleNames, etc. as described in the tutorial.

I tried to deploy my login module to ${jetty_home/lib, but not succeed.

Your help is appreciated.
