I want to have multiple JDBC-connections (to mySQL databse) in my servlet.
For each servlet I use:
After establishing JDBC connection to SocialNetwork DataBase, I use insert, and update queries to add/update the records on my userInfo db.
i want the same JDBC connection to use in another servlet[userLogin] in the same application/package.
Is there a way I can create another connection servler/class and import it and use it in all other Httpservlets responsible for registering a new user , checking records, updating records etc..in the same SocialNetwork Db but different tables??
The 'UserLogin' servlet checks two records userName and Password in 'registredUser' table when the user logs-in through a login.jsp page with userName and password.
I am getting input parameters onto the UserLogin servlet from Login.jsp as below
How should i go about checking name and password in terms of sql queries- right now I am trying to use
to make it clear I have 2 tables[ registredUser and UserInfo.
RegistredUser has these colums- UserId, userName, Password, Age and city. user Id is PK and AI.
UserInfo has userId, userName and Password. User Id is PK and AI in this table too.
How can i establish a relation between userID in two different tables and check/authenticate the userName and password??
