I am using sqlserver with Windows authentication, with a Windows server.
I am trying to connect to a remote MS SQLSERVER on my local network using java eclipse but keep getting this error:
Error : com.microsoft.sqlserver.jdbc.SQLServerException: The port number 64038 databaseName = Data is not valid.
Here is the code:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
System.out.println("# - driver loaded");
String server = "moddbs169d.network.local\\Moddbs169d\\SQL2008";
int port = 64038;
String database = "Data";
String jdbcUrl = "jdbc:sqlserver://"+server+":"+port+" databaseName = "+database+";integratedSecurity=true";
Connection con = DriverManager.getConnection(jdbcUrl);
System.out.println("# - Connection obtained");
If all is successful it should tell me connection obtained. The local connection and name of the database are both correct, so that is not the issue. The jdbc driver is also installed and working properly.
You are missing a semicolon before the "databaseName=xxx" property.
Without the semicolon, you are setting the port number to "64038 databaseName = Data". Admittedly, the error message could have used brackets to make it a bit clearer.
See (http://msdn.microsoft.com/en-us/library/ms378428(v=sql.110).aspx) for the form of the connection URL.

I need to connect to an external database to copy data from there to my table. I have a TNS file for this external database, and I am trying to connect using JDBC like this:
try {
conn = DriverManager.getConnection("jdbc:oracle:thin:#(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=" +
host +
")(PORT=" +
port +
")))(CONNECT_DATA=(SERVICE_NAME=" +
service +
")))",
user,
password);
...
But when trying to connect, i get the error java.net.UnknownHostException (host is not recognized). I guess the problem is that this is an internal host and I don't have access to it.
How to connect to the database using TNS?
You should not need the full TNS text. The following should suffice
getConnection("jdbc:oracle:thin:myuser/mypass#//"+host+":"+port+"/"+service);
If you have a tnsnames.ora then, you can provide the TNS alias as part of your connection string. Make sure you try to login to the Oracle Database through sqlplus using the connection string present in tnsnames.ora.
// dbname_tnsalias - It is the TNS alias present in tnsnames.ora.
// TNS_ADMIN --> Absolute path where tnsnames.ora is present.
final String DB_URL="jdbc:oracle:thin:#dbname_tnsalias?TNS_ADMIN=/Users/test/";
I'm trying to connect to my Openshift MYSQL database on a database called OTA
Whenever i try to connect i get the error -
java.sql.SQLException: Access denied for user 'admin881Rhs7'#'localhost' (using password: NO)
While i'm using a password
private String ConnectionString = "jdbc:mysql://localhost:3306/OTA?"
+ "user=admin881Rhs7&password=9JDlLn1r****";
public ResultSet ExecuteSQL(String query) throws Exception {
try {
Class.forName("com.mysql.jdbc.Driver");
// setup the connection with the DB.
connect = DriverManager.getConnection(ConnectionString);
// statements allow to issue SQL queries to the database
statement = connect.createStatement();
// resultSet gets the result of the SQL query
resultSet = statement.executeQuery(query);
// writeResultSet(resultSet);
I can't seem to connect to the remote database using this connection, but I can logon onto the database using PHPMyAdmin
Note: I've tried changing "localhost" in my connection String to the IP of the server on database and doesn't work either
I've also granted my user previlages and still says (using password: NO )
Any help is appreciated , please note that this is on open-shift servers.
If you are running this app on OPENSHIFT you need to replace the localhost by MySQL server IP, you can get the IP using this command
rhc port-forward -a <mysql-gear-name>
and then used the same IP DriverManager
DriverManager.getConnection("jdbc:mysql://X.X.X.X:3306/OTA", "admin881Rhs7", "9JDlLn1r****")
I'm having trouble with my distributed application in java netbeans the program is running perfectly on the original machine where i created it. but when i build it and make a distribute folder and follow the instructions and try to run it, I got an error that localhost on port 1527 has been refused.
here is my code on my do connect function
public void DoConnect()
{
String host = "jdbc:derby://localhost:1527/KempDB";
String uName = "main";
String uPass = "admin";
try
{
con = DriverManager.getConnection(host, uName, uPass);
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
String sql = "select cv.checkvouchernumber, c.checknumber, paytoorder, bankcode, dateissued, amount from checkvoucher cv, checks c where cv.checkvouchernumber = c.checkvouchernumber and cv.checknumber = c.checknumber";
rs = stmt.executeQuery(sql);.....
..........
}
catch(SQLException err){
.......
}
so this is the code I used to connect with the database server, the database server I used is built-in with java. Its a apache derby...
like I said in the original machine where I created the program runs ok without errors but when I distribute the program to another machine there's an error refusing the connection.
How can I connect to the local machine where my database is? maybe you can help me on this.
Are the database Servers running on these machines?
Are u starting the database server programmatically?
If you try to connect a database Server with:
jdbc:derby://localhost:1527/KempDB
This Server needs to be up and running.
For your case you should use an embedded Database.
For the case your Database is already an embedded Database, then you can try using this URL:
jdbc:derby:KempDB
instead of:
jdbc:derby://localhost:1527/KempDB

I am trying to connect to HP Operations Manager Database using Java code in Eclipse IDE.
I am able to connect successfully through Microsoft SQL Server Management Studio 2008 but it fails through code.

System.out.println(url);
try{
Class.forName(driverName).newInstance();
dbConnection = DriverManager.getConnection(url,userName,password);
System.out.println(DriverManager.getDrivers());
statement = dbConnection.createStatement();
String QueryString = "select Id from openview.dbo.OV_MS_Message where OriginalServiceId like '{FaultDn[1]}'";

I have explicitly added an inbound rule in windows firewall to allow UPD traffic on 1434 port, then disabled the firewall. But I still get this error.
The credentials provided here are used for connection using Microsoft SQL Server Management Studio and it works perfectly fine. But it fails through the code.
I am not sure where I am going wrong. I am unable to establish a successful connection through the code. Please help me.
Hey Thanks all for your responses. Finally I was able to resolve the issue. The problem was with the url and auth dll. Changed the url to
"jdbc:sqlserver://10.105.219.102:1433;instance=OVOPS;DatabaseName=openview;integratedSecurity=true"
and added the location of "sqljdbc_auth.dll" in java.library.path. It worked!
Thanks again for your efforts to help me :)
It took me a while to sort this issue out, but you have to head into the SQL Server Configuration Manager application. When that's loaded, expand the [SQL Native Client 11.0 Configuration] > Client Protocols.
Enable all three (Shared Memory, TCP/IP, and Named Pipes), if they aren't already.
Then click on TCP/IP and ensure that the default port is 1433.
If you have a 32bit system or version of SQL Server installed, do the same in the SQL Native Client 11.0 Configuration (32it) menu, enabling Shared Memory, TCP/IP, and Named Pipes and setting the default port to 1433.
Then click open the [SQL Server Network Configuration] or (32bit if applicable), and select the [Protocols for "YOURSERVERNAME"].
Ensure again that Shared Memory, TCP/IP, and Named Pipes are all enabled.
Then click on the [TCP/IP] Protocol Name, then select the [IP Addresses] tab at the top of the new popup window. For IP1 ensure that Active is YES; Enabled is YES (this is No by default, even if it is Active); and set the TCP Port to 1433 (tbh I don't know if you have to do this step, but I did and it worked!!); my TCP Dynamic Ports are set to 0 and I didn't change any of the IP addresses;
I did the same thing for IP10, which has IP: 127.0.0.1, which is the local machine.
I also scrolled down to the bottom of the page, and set IPAll TCP Ports to 1433, (dynamic ports is 49163).
Then you need to Apply all changes, close the properties window, and click on SQL Server Services in SQL Server Configuration Manager, and restart all running Servers.
This should do it :D
Catch example:
String url = "jdbc:sqlserver://localhost:1433/databaseName";
String username = "user";
String password = "pass";
Connection connection = DriverManager.getConnection(url, username, password);
1433 is default port.
Dont use '\' in url.
This is probably not an answer to your question, but I hope this will help you. Here is the way how to properly return connection (mysql):
import java.sql.*;
public class ConnectToDatabase{
public Connection getConn(){
final String DBPATH="jdbc:mysql://localhost:3306/mydb";
final String DBUSER="root";
final String DBPASS="";
Connection conn=null;
try {
conn = DriverManager.getConnection(DBPATH,DBUSER,DBPASS);
} catch (SQLException e) {
e.printStackTrace();
}
return conn;
}
}
Try changing your database user password. Make sure new password doesn't have special characters.
I faced same problem and it got resolved after changing the db password.
Steps of my workaround:
I was getting sqlserverexception.java 190 error stating unable to connect to host port: 4500 which was my localhost port.
Opened Sql Server Configuration Manager -> SQL Server Network Configuration -> Protocols for MSSQLSERVER -> Enabled TCP/IP.
Checked TCP port number. It was 1433. So I changed 4500 to 1433 in my registry file.
After following above steps, I got a different error this time startingpassword for my db user(sql-test) is incorrect. I changed the password to sqltest123 and it worked.
i ran into a weird problem when connecting to mysql using java.
i'm running xampp with tomcat
i tried connecting to mysql from java. on my machine it works fine, but on a friends machine i get an error: access denied for user 'tomcat'#'localhost'
thing is - i managed to connect with the exact same info using php.
the java code for the connection is:
String url = "jdbc:mysql://localhost:3306/";
String dbName = "mta_db";
String driver = "com.mysql.jdbc.Driver";
String userName = "tomcat";
String password = "tomcat";
try {
Class.forName(driver).newInstance();
_conn = DriverManager.getConnection(url + dbName, userName, password);
} catch (Exception e) {
e.printStackTrace();
}
port is fine
any idea what could be the cause?
The error is probably on the MySQL side, that is, the tomcat user doesnt have privileges to connect from non-localhost.
For simplicities sake you can first create an account that is able to connect from anywhere, via the MySQL GRANT statement like so:
GRANT ALL ON mta_db.* to tomcat#'%' identified by 'yourpassword';
In this case the % is a wildcard for any host.
If you know the actual IPs of your connecting clients you can later crack it down, to be more security conscious.
