user and password refer Username and Password that used to connect to the SQL Server.

databaseName=Northwind refers to the database name you want to connect to.

localhost:1433 refers to connect to SQL Server at localhost port 1433 (default port).Class.forName(“.SQLServerDriver”) means load the SQL Server driver.("Class Not Found Exception: "+ cE.toString()) "databaseName=Northwind user=sa password=123456 " Ĭonnection con = DriverManager.getConnection(connectionUrl) String connectionUrl = "jdbc:sqlserver://localhost:1433 " + Now I will connect to my SQL Server on local machine, the Northwind database(a sample database in SQL Server 2000).I’m going to use Connection and DriverMapper Classes so I need to import libraries.

Let continue from the project just created in previous step, in main.java. Assume that I have SQL Server 2000 running on local machine.

#NETBEANS COULD NOT FIND OR LOAD MAIN CLASS HOW TO#

I going to show how to connect to SQL Server. If you delete the file without delete a link from the project, the project will show error about missing library. May be in the same directory that keep common library files. Note: You should keep sqljdbc.jar in the directory that you won’t delete it (ex. New Window appears, browse to the file ‘sqljdbc.jar’ and click Open.And on right side in Compile tab, click Add JAR/Folder. The Categories on left side, select Libraries. In Projects window, right click the project name and select Properties.I will show by create New Java Application Project called TestSQL and add ‘sqljdbc.jar’ that just get from previous step to the project’s library.

#NETBEANS COULD NOT FIND OR LOAD MAIN CLASS DRIVER#

Add JDBC Driver to the project on NetBeans.

You can find more informations about JDBC Driver at \Microsoft SQL Server 2005 JDBC Driver\sqljdbc_1.1\enu\help\default.htm.

Then, you’ll see the folder that you’ve just extracted ( \Microsoft SQL Server 2005 JDBC Driver\sqljdbc_1.1\enu\ ), the file ‘sqljdbc.jar’ which is the library that will be added to the library in NetBeans later.

Double-click sqljdbc_.101_enu.exe to extract it.

(The file name may differs depends on the version if you’ve downloaded from the Official Site.)

#NETBEANS COULD NOT FIND OR LOAD MAIN CLASS DOWNLOAD#

Download Microsoft SQL Server 2005 JDBC Driver, name ‘sqljdbc_.101_enu.exe’.

NetBeans with JRE (Java Runtime Environment) version 1.4 or later.

To get latest version, visit Microsoft SQL Server 2005 JDBC Driver. The last part is about problems and how to fix them.

#NETBEANS COULD NOT FIND OR LOAD MAIN CLASS UPDATE#

For instance, send querys as SELECT, INSERT, UPDATE to the database. This part show how to perform some basic operations from NetBeans with SQL Server. In this example, I use SQL Server 2000 SP4 and NetBeans IDE 5.5 Public class RoA_ extends part which you’re reading shows about how to establish a connection between NetBeans and SQL Server. Here is my Package contents:Īnd this is the beginning of the java file: package exec-maven-plugin:1.2.1:exec (default-cli) RoA_ -Ī Maven project implementing an ImageJ 1.x plugin. Phase execution is skipped and output directories of dependency projects (with Compile on Save turned on) will be used instead of their jar artifacts. Running NetBeans Compile On Save execution.

I think my pom.xml file is a mess, but I don’t have a clear idea on how to fix it. Look above for specific messages explaining why the rule failed.
