HSQLDB束未發現

我有一些代碼，加載什麼： 1）HSQLDB v 2.2.8捆綁 2）與捆綁服務：HSQLDB束未發現

package ihtika2.i_internalfunctions.service; 

import com.google.code.ihtika.Vars.Ini; 
import java.awt.Desktop; 
import java.io.IOException; 
import java.net.URI; 
import java.net.URISyntaxException; 
import java.sql.DriverManager; 

/**

* @author Arthur 
*/ 
public class InternalFunctions implements InternalFunctionsInterface { 

    // launch browser 
    public void launchBrowser(String uriStr) { 
     Desktop desktop; 
     if (Desktop.isDesktopSupported()) { 
      desktop = Desktop.getDesktop(); 
      if (desktop.isSupported(Desktop.Action.BROWSE)) { 
       // launch browser 
       URI uri; 
       try { 
        uri = new URI("http://" + uriStr); 
        desktop.browse(uri); 
       } catch (IOException ioe) { 
        ioe.printStackTrace(); 
       } catch (URISyntaxException use) { 
        use.printStackTrace(); 
       } 
      } 
     } 
    } 

    public void initDB() { 
     try { 
      Class.forName("org.hsqldb.jdbcDriver"); 
      Ini.conn = DriverManager.getConnection("jdbc:hsqldb:file:Db/pages"); 
      Ini.stmt = Ini.conn.createStatement(); 
      Ini.rs = null; 

      Ini.rs = Ini.stmt.executeQuery("select count(1) as qwe from " 
        + " information_schema.system_tables " 
        + "where table_schem = 'PUBLIC'" 
        + "and table_name = 'PAGES';"); 
      Ini.rs.next(); 
      if (Ini.rs.getInt("qwe") == 0) { 
       Ini.stmt.executeUpdate("CREATE SEQUENCE SEQU"); 
       Ini.stmt.executeUpdate("CREATE CACHED TABLE PAGES (id bigint " 
         + "GENERATED BY DEFAULT AS SEQUENCE SEQU PRIMARY KEY, " 
         + "url varchar(7777), lastUpdateDate varchar(7777)) "); 
       Ini.stmt.executeUpdate("CREATE CACHED TABLE LINKDATA (id int, " 
         + "nazvanie varchar(777), linkURL varchar(777), razmer varchar(777)) "); 
       Ini.stmt.executeUpdate("CREATE INDEX linkDataID ON LINKDATA (id)"); 
       Ini.stmt.executeUpdate("CREATE INDEX pagesURL ON PAGES (url)"); 
      } 
     } catch (Exception ex) { 
      Ini.logger.fatal("Error on DB init", ex); 
     } 
    } 
}

3）有些包，什麼叫捆數2

try { 
     ServiceReference[] refs = context.getServiceReferences(
       InternalFunctionsInterface.class.getName(), "(Funct=IFuncts)"); 
     if (refs == null) { 
      System.out.println("Not Found IFuncts on init"); 
     } else { 
      InternalFunctions = (InternalFunctionsInterface) context.getService(refs[0]); 
     } 
    } catch (Exception ex) { 
     Ini.logger.fatal("Error on IFuncts init", ex); 
    } 

    InternalFunctions.initDB();

上執行我得到了記錄錯誤：

請教，如何在其他包中使用HSQLDB包？

由我回答：的解決方案是使用

DriverManager.registerDriver(new JDBCDriver()); 
Ini.conn = DriverManager.getConnection("jdbc:hsqldb:file:Db/pages");

insted的使用

Class.forName("org.hsqldb.jdbcDriver"); 
Ini.conn = DriverManager.getConnection("jdbc:hsqldb:file:Db/pages");

如果您發現自己問題的解決方案，請將其作爲答案發布，而不是編輯自己的問題。然後你可以接受這個答案，這樣別人就可以看到它被解決了。 – 2012-08-02 18:21:18

不幸的是，這是一個非常不友好的OSGi的解決方案。你可能想看看H2。 H2實現了OSGi規範，它提供了一個org.osgi.service.jdbc.DataSourceFactory服務。您可能還想在hsqldb項目中發現一個錯誤，並要求提供OSGi支持，實現它們非常簡單。
