As you are getting the error from Oracle side. Which means your JDBC driver is passing your connection string & credentials to the DB but the DB is rejecting due to incorrect username/password. with the error code ORA-01017
java.sql.SQLException: ORA-01017: invalid username/password; logon denied
at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:447).
So it will be best to try using some Standalone Java Program (Or some native clients like sqlplus client) to validate if your DB username & Password is correct or not? Or if it is expired? The credentials are case sensitive.
.
So we should isolate the issue first whether oyu are entering valid credentials ? Following link provides some generic tips from Oracle side: http://www.dba-oracle.com/t_ora_01017.htm
.
You can try the following Java code to validate if you are able to connect to the oracle DB . You only need to change the following code with your DB connection URL , dbUsername & dbPassword in the following line
"jdbc:oracle:thin:@host:port:sid","scott","tiger"
.
vi /tmp/JDBCVersion.java
import java.sql.*;
import oracle.jdbc.driver.*;
public class JDBCVersion {
public static void main (String args []) throws SQLException {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@host:port:sid","scott","tiger");
DatabaseMetaData meta = conn.getMetaData ();
System.out.println("JDBC driver version is " + meta.getDriverVersion());
}
}.
How to compile and run.
cd /tmp
ls -l /tmp/JDBCVersion.java
export CLASSPATH=/PATH/TO/ojdbc7.jar:.:
javac JDBCVersion.java
java JDBCVersion
.
