JENA:初始化HSQLDB RDF数据存储

我正在尝试初始化 RDF公司 数据存储使用 耶拿 和 HSQLDB公司 . 从 http://jena.sourceforge.net/DB/hsql-howto.html 我写了以下代码:

import com.hp.hpl.jena.db.DBConnection;
import com.hp.hpl.jena.db.IDBConnection;
import com.hp.hpl.jena.db.impl.Driver_HSQL;
import com.hp.hpl.jena.rdf.model.Model;
import com.hp.hpl.jena.rdf.model.ModelFactory;
import com.hp.hpl.jena.rdf.model.ModelMaker;

public class Test
    {
    /** */
    private String idbDriver="org.hsqldb.jdbcDriver";
    private String idbUrl="jdbc:hsqldb:file:/home/me/DATASTORE.HSQLDB";
    private String idbUser="sa";
    private String idbPassword="";

    /** RDF Model */
    private Model model=ModelFactory.createDefaultModel();
    /** IDB connection */
    private IDBConnection idbConnection=null;

    public Test()
        {

        }

    public void open() throws Exception
        {
        close();
        Class.forName(idbDriver);
        this.idbConnection = new DBConnection(idbUrl, idbUser, idbPassword, "HSQL");
        ModelMaker maker = ModelFactory.createModelRDBMaker(this.idbConnection) ;
        this.model=maker.createDefaultModel();
        }

    public void close()throws Exception
        {
        this.model=null;
        if(this.idbConnection!=null)
            {
            // http://jena.sourceforge.net/DB/hsql-howto.html
            Driver_HSQL.class.cast(this.idbConnection.getDriver()).shutdown();
            this.idbConnection.close();
            this.idbConnection=null;
            }
        }

    public Model getModel()
        {
        return model;
        }

    public static void main(String[] args)
        {
        try {
            Test app=new Test();
            app.open();
            app.close();
            } 
        catch (Exception e)
            {
            e.printStackTrace();
            }
        }

    }

但是当程序执行时,我得到了以下异常:

 INFO [main] (?:?) - DataFileCache.close() : save data

我怎样才能解决这个问题?

非常感谢,
