Error When Trying Run SQL Server Query through Netbeans

My application is building successfully but won't run the query. Here's what I've done so far:
Downloaded JDBC Driver and used to successfully create connection to database, which is showing in services tab
Added CLASSPATH variable and added C:\Program Files\Java\jre1.8.0_221\bin;C:\Program Files\Java\jdk1.8.0_221\bin;.;C:\Program Files\Java\Microsoft JDBC Driver 7.4 for SQL Server\sqljdbc_7.4\enu\mssql-jdbc-7.4.1.jre8.jar as well as my JRE and JDK bin folders and .
Run below code
import java.sql.*;
public class TestCode {
public static void main(String[] args)
{
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url = "jdbc:sqlserver://mysqlserver:1433;databaseName=mydatabase;integratedSecurity=false;";
Connection conn = DriverManager.getConnection(url, "username", "password") ;
Statement stmt = conn.createStatement();
ResultSet rs;
rs = stmt.executeQuery("SELECT TOP 10 UserID FROM dbo.Users");
while (rs.next())
{
String userID = rs.getString("UserID");
System.out.println(userID);
}
}
catch (Exception e)
{
System.err.println("Error");
System.err.println(e.getMessage());
}
}
}
The error I'm getting is:
Error
com.microsoft.sqlserver.jdbc.SQLServerDriver
Which is the just the name of my driver. I got this from right clicking on the driver, clicking customize and copying the Driver Class from this Window.

Fixed.
Needed to add JDBC driver file to project library

SQL Server conecction with jdbc eclipse

I have the following code to connect to my database in SQL Server:
public static void main (String [] args) {
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url = "jdbc:sqlserver://DESKTOP-G8057U8\\SQLEXPRESS:1433;databaseName=Vaporizadores;integratedSecurity=true;";
DBConection=DriverManager.getConnection(url);
DBStatement = DBConection.createStatement();
System.out.println("Conexion exitosa");
}catch(ClassNotFoundException | SQLException e) {
System.out.println("Conexion fallida");
}
}
when I run it I get "Conexion fallida", meaning that an exception was catched. I've tried different urls but I still can't connect to my DB. I know very little about jdbc and sql server, so it may be a stupid error.

It worked like this:
String url = "jdbc:sqlserver://DESKTOP-G8057U8;databaseName=Vaporizadores;integratedSecurity=true;";
and i added the sqljdbc_auth.dll to Java bin folder

jdbc mysql driver not found after deploying

I have developed a REST application using jersey where to connect to database(mysql) I use jdbc connection. Following is the configuration.
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
static final String DB_URL = "jdbc:mysql://localhost:3306/DBNAME";
static final String USER = "root";
static final String PASS = "********";
public List<Item> getAll() {
List<Item> results = new ArrayList<>();
try (Connection conn = (Connection) DriverManager.getConnection(DB_URL,
USER, PASS);
Statement stmt = (Statement) conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM items");) {
while (rs.next()) {
// Retrieve by column name
System.out.println(rs.getInt("ID"));
System.out.println(rs.getString("FormerCode"));
System.out.println(rs.getString("NewCode"));
results.add(new Item(rs.getInt("ID"), rs
.getString("FormerCode"), rs.getString("NewCode")));
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return results;
}
All things works when I deploy via Eclipse. But when I create the war file and deploy it manually on tomcat server it gets the exception saying there is no suitable driver.
No suitable driver found for 'jdbc:mysql://localhost:3306/DBNAME
I have included the mysql-connector jar files in both WEB-INF/lib folder and TOMCAT_HOME/lib folder. But I am still getting this error. Server is running on Ubuntu Server 14.04.
Paths where jar is added.
src/main/webapp/WEB-INF/lib
usr/share/tomcat7/lib
What seems to be the problem hence I have added the jar files to necessary locations??

Sometimes java class failed to pick driver's(mysql java connector jar file) path from lib folder. To remove this issue you can extract connector jar in following directory of your project.
src/main/webapp/WEB-INF/classes
OR
You may also compile the java file with classpath reference of mysql_java_connector.jar.

The answer was when using a DriverManager interface to create a JDBC Connection, always create an instance of your JDBC driver first in order to load it into your Classloader.
try {
// The newInstance() call is a work around for some
// broken Java implementations
Class.forName("com.mysql.jdbc.Driver").newInstance();
} catch (Exception ex) {
// handle the error
}
Thanks all.

JDBC not connecting

While the build paths are not correct I obtain “com.microsoft.sqlserver.jdbc.SQLServerDriver” from the stack trace. As they are built correctly, I obtain my printed statement “Successfully connected”. The JDBC is living within the getter/setters of the webservice as a method.
When I place the JDBC content in its own file with no builds and run as a java application I receive: “com.microsoft.sqlserver.jdbc.SQLServerDriver”
When I place the JDBC content in its own file with builds and run as a java application I receive: “Successfully connected”
When the method is called from a test file as a java application I receive: “Successfully connected”
Ex:
public static void main(String[] args) {
insert.main(args);
When the method is run as a java application on PO I receive: “Successfully connected”
When I place the method to be called under a setter (which will be invoked by the client, which will cause the jdbc to be invoked) I receive: “com.microsoft.sqlserver.jdbc.SQLServerDriver”
Would you happen to have any tips for me? I’m clueless why it will work under being invoked as an application but not via client?
public class insert{
public static void main(String[] args) {
Connection con = null;
Statement st = null;
final String DB_URL = "jdbc:jtds:sqlserver://00.00.00.00:0000/DB";
// Database credentials
final String USER = "usrname";
final String PASS = "pw";
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(DB_URL, USER, PASS);
st = con.createStatement();
System.out.println("successfully connected!");
} catch (Exception err) {
System.out.println(" " + err.getMessage ());
}
finally {
try {
con.close();
} catch (Exception e) { /* ignored */ }
try {
st.close();
} catch (Exception e) {
/* ignored */
}
}
}
}
Any tips at this point would be greatly appreciated.

The problem is that your jar misses the necessary libraries that provides com.microsoft.sqlserver.jdbc.SQLServerDriver class and others to communicate with your SQL server. You have to make sure the library is loaded and available when is being executed from tomcat. Just copy your library and drop it inside %TOMCAT_INSTALL%/lib folder, where %TOMCAT_INSTALL% is the folder where your tomcat is installed, so the library will be available for every project (war, jar, etc) that runs in your tomcat installation.

Connecting a Java application to an SQL database with Eclipse

I know this has been asked before but I really can't get this to work and as far as I can see I've followed all the steps.
I'm using Eclipse.
So I downloaded the Microsoft SQL Driver sqljdbc v4.0.
I created a new project and class. I edited the build path by adding the .jar file to the libraries.
I typed the following code:
package com.test.sql;
import java.sql.*;
public class Connect
{
public static void main (String[]args)
{
Connection con = null;
String conURL = "jdbc:sqlserver://localhost; databaseName=AnotherTestDB;";
try
{
con = DriverManager.getConnection(conURL);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
I got the following error:
java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost; databaseName=AnotherTestDB;
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.test.sql.Connect.main(Connect.java:11)
A bit more research and I was told put it in the java /lib/ext and reference it from there.
Nothing changed.
Any help?
Thanks.

Normally you need to register the driver before accessing to it:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

Try with something like this:
String DRIVER = “oracle.jdbc.driver.OracleDriver”;
String DBURL = “jdbc:oracle:thin:#jiplc0.si.ehu.es:1512:Erreala”;
String UID = “USERNAME”;
String PWD = “PASSWORD”;
Driver kontrolatzailea = (Driver) (Class.forName(DRIVER).newInstance());
DriverManager.registerDriver(kontrolatzailea);
DefaultContext test = new DefaultContext(DBURL, UID, PWD, false);
DefaultContext.setDefaultContext(test);

Thanks for the responses.
I had both the sqljdbc4.jar and sqljdbc.jar referenced. The version of Java I am using requires that I use sqljdbc4.jar but it was being overwritten by sqljdbc.jar so I removed it.
I also changed my code to this:
public static void main (String[] args)
{
try
{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://nameMyLaptop//SQLEXPRESS";
Connection con = DriverManager.getConnection(connectionUrl);
}
//Insert catches
}
Apparently I didn't have to change the code but its not giving me that error now. I'm getting a new one but that's unrelated to my question.
Thanks for your time and responses.

You have to add the SQL JDBC Driver in your project libraries. download jtds.jar and add to your libraries. And follow the code below.
public static void main (String[] args) throws Exception{
Connection conn=null;
String url="jdbc:jtds:sqlserver://YourServerIp:1433/dbName";
String username="sa";
String password="****";
String driver="net.sourceforge.jtds.jdbc.Driver";
// Step 1: Load the JDBC driver.
Class.forName(driver);
// Step 2: Establish the connection to the database.
conn= DriverManager.getConnection(url, username,
password);
}
Here you have to follow two steps......
