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
);
