i tried to create a login page using JDBC realm but did not works.
My steps :
- Create database, user and group table
- Create connection pool and data source, custom realm.
- Add security roles mapping, login constraint, security constraint and
security roles.- Create login jsp and login servlet
I can ping the connection pool during creation.
What is the minimal configuration require to perform the above task ?
My Code :
create table login
(
username varchar(128) NOT NULL CONSTRAINT usernamePk primary key,
password varchar(128) NOT NULL
);
insert into Login values('peterwkc', '1234');
create table grouptable
(
username varchar(128) NOT NULL,
groupid varchar(128) NOT NULL,
CONSTRAINT GROUP_PK PRIMARY KEY(username, groupid),
CONSTRAINT USER_FK FOREIGN KEY(username) REFERENCES Login (username)
ON DELETE CASCADE ON UPDATE RESTRICT
);

I follow this tutorial.

Questions :
1. Why my code does not working ?
Please help.
Thanks.
If you followed the tutorial, Glassfish expects to find MD5 hashes of the passwords in
usertable. But you inserted1234. You will either have to insert the MD5 hash of1234which is:81dc9bdb52d04dc20036dbd8313ed055or you could tell Glassfish to use plain passwords, but I don’t know what to put in theDigestthen.HTH
EDIT
In the tutorial the realm name is
securitybut in your web.xml it is namedLoginEDIT 2
There is even more wrong:
To use the automatic login mechanism of Glassfish the form in your Login.jsp should have
action="j_security_check"and the names for user and password should bej_usernameandj_passwordrespectively.Also see Matt Handy’s answer and comment and provide some more details (such as error message or so). Otherwise it’s very difficult to help if you just say “It doesn’t work”
