java - How to check login and password from DataSource? -

any user have login/password in oracle database. have code:

connection con; statement stmt = null; string query = "select user dual"; try {     datasource = (datasource) new initialcontext().lookup("jdbc/mydatasource"); } catch (namingexception e) {     throw new exceptionininitializererror(e); } try {     system.out.println("name, password:" + name + "|" + password);     con = datasource.getconnection(name, password);     stmt = con.createstatement();     resultset rs = stmt.executequery(query);     while (rs.next()) {         system.out.println("user:" + rs.getstring("user"));     }     con.close();     return true; } catch (sqlexception ex) {     logger.getlogger(userinfoserviceoracle.class.getname()).log(level.severe, null, ex);     return false; } 

if put correct password, next user getconnection using login/password , login/password first correct user.

log:

info:   name, password:correctuser|correctpassword info:   user:correctuser info:   name, password:jhkjhkjh|khkjhkj info:   user:correctuser 

a datasource facade connection pool.

• as confirmed you. if supply incorrect password, datasource returns connection. means datasource not bothering username password supplying it.

• as pointed out others on here, datasource configured , created application server. server reads appropriate parameters (like, username/password, initial number of connection, max number of connection etc) configuration file (some xml) , creates connection (initial no. of connection) used application later.

• so when call datasource.getconnection, datasource returning already created connections. username/password supplied has no effect.
