java调用kettle资源库实例

wx_1021 2016-07-02 11:07:52

如题，代码中第二句就报找不到类，请大神帮忙看看是jar包不够，还是哪里有错



public static void main(String[] args) throws KettleException {

		// TODO Auto-generated method stub

		

		//初始化环境

        KettleEnvironment.init();

        //创建DB资源库

        KettleDatabaseRepository repository=new KettleDatabaseRepository();   // 报异常，说一个类找不到

        DatabaseMeta databaseMeta=new DatabaseMeta("mysql","mysql","jdbc","localhost","test","3306","root","root");

        //选择资源库

        KettleDatabaseRepositoryMeta kettleDatabaseRepositoryMeta = new KettleDatabaseRepositoryMeta("kettle_resource","kettle_resource","Transformation description",databaseMeta);

        

        repository.init(kettleDatabaseRepositoryMeta);

        //连接资源库

        repository.connect("admin","123");

        RepositoryDirectoryInterface directoryInterface=repository.loadRepositoryDirectoryTree();

        //选择转换

        TransMeta transMeta=repository.loadTransformation("test",directoryInterface,null,true,null);

        Trans trans=new Trans(transMeta);

        trans.execute(null);

        trans.waitUntilFinished();//等待直到数据结束

        if(trans.getErrors()>0){

            System.out.println("transformation error");

        }else{

            System.out.println("transformation successfully");

        }

}

引用的jar

异常如下：
