Read through the code, ran some example stuff. What I'm doing in my implementation is fine.

No, that can't be the issue.

I'll go look into that.

In JNDIRealm authenticate(String, String) gets a DirContext and calls authenticate(DirContext, String, String). Your code snippet which I assume overrides, authenticate(DirContext, String, String) which calls super.authenticate(String, String). Then ... super.authenticate(String, String) calls authenticate(DirContext, String, String) which you had overridden which is indirect recursion. -Tim Hart, Justin wrote: > Ok, why? > > What am I doing that should cause a stack overflow? > > Justin > > -----Original Message----- > From: Tim Funk [mailto:[EMAIL PROTECTED] > Sent: Monday, November 24, 2003 7:26 PM > To: Tomcat Users List > Subject: Re: Extending JNDIRealm > > > Odd, based on what I see so far, I would expect it to crash with a > StackOverFlow exception. > > -Tim > > Hart, Justin wrote: > >>Whoops, the code is actually as follows... >> >>No sure what's going on with this code...
