Question

我目前正尝试将一些数据导出，转换并加载到数据库，以便稍后进行一些分析。但是，在运行应用程序时，它会给我一个错误！

以下是代码：

import org.pentaho.di.core.KettleEnvironment;
import org.pentaho.di.core.exception.KettleException;
import org.pentaho.di.trans.Trans;
import org.pentaho.di.trans.TransMeta;

public class HelloWorldTest
{
    public static void main(String args[])
    {
        try {
            KettleEnvironment.init();
            TransMeta metaData = new TransMeta("try.ktr");
            Trans trans = new Trans( metaData );
            trans.execute( null );
            trans.waitUntilFinished();
            if ( trans.getErrors() > 0 ) {
                System.out.print( "Error Executing transformation" );
            }
        } catch( KettleException e ) {
            e.printStackTrace();
        }
    }
}

以下是错误：
