Tomcat issue with custom JAASLogin module

[Suresh Bab]

Hi ,

I had written a custom login module using JAAS and deployed the application in Tomcat server.

I am getting exception like , ( Sample is the name of the config file )

How are you specifying the login.config to your JAAS.

[Suresh Bab]

Hi Rahul,

This is my login.config file,

JAASLoginModule{
com.<<<****>>>.customLogin.SampleJAASLoginModule
required
debug=true;
}

i had solved the previous error but know i am getting another exception like,

javax.security.auth.login.LoginException: unable to find LoginModule class: com.<<*********>>.customLogin.SampleJAASLoginModule
at javax.security.auth.login.LoginContext.invoke(LoginContext.java:711)
at javax.security.auth.login.LoginContext.access$000(LoginContext.java:129)

Hi ,

I went thorugh the LoginContext class of rt.jar and found that it is not able to load the SampleJAASLoginModule class.

Can any one tell me how i can solve this class loader exception i.e class not found exception.

I had even set the classpath of that particular file but still the same problem persists.

Thanks,
Suresh
