Question

I’ve got the following java code, which is giving the error below:

import java.io.File;
import java.io.FileOutputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import org.dbunit.database.DatabaseConnection;
import org.dbunit.database.IDatabaseConnection;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.xml.FlatXmlDataSet;

public class export {
    public static void main(String[] args) throws Exception {
        // database connection
        Class.forName("net.sourceforge.jtds.jdbc.Driver");
        Connection jdbcConnection = DriverManager.getConnection(
            "jdbc:jtds:sqlserver://localhost:1433/exampleDB", "sa", "vista1");
        IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);

        // full database export
        IDataSet fullDataSet = connection.createDataSet();
        FlatXmlDataSet.write(fullDataSet, new FileOutputStream("full.xml"));
    }
}

Error:

$ java export

Exception in thread "main" java.lang.NoClassDefFoundError: org/dbunit/database/IDatabaseConnection

Could not find the main class: export.  Program will exit.

The name of the java file being compiled is export.java and the name of the compiled file is export.class, and I’ve put the dbunit-2.4.8.jar and jtds-1.2.5.jar files in to the same folder as export.java and export.class; and I’m compiling export.java with the following cmd:

$ javac -cp "dbunit-2.4.8.jar;jtds-1.2.5.jar" export.java

Any idea what I’m doing wrong?

Answer 1

I’m using this on an oracle database and it works fine ^^

IDatabaseConnection connection = new DatabaseConnection(jdbcConnection, "SCHEMA_OF_YOUR_DB");
