我遇到了JDBC问题.

我有以下代码:

//blargeparam is a blob column.
PreparedStatement pst =connection.prepareStatement("update gcp_processparams_log set blargeparam= ? where idprocessparamslog=1");

pst.setBinaryStream(1,inputStream);         

我收到以下错误:

Exception in thread "main" java.lang.AbstractMethodError:           
oracle.jdbc.driver.T2CPreparedStatement.setBinaryStream(ILjava/io/InputStream;)V  

我的连接字符串是 jdbc:oracle:oci:@.....

Oracle版本为11g.

从错误消息似乎缺少某些东西但是:

• 当我从相同的blob列(使用blob.getBytes)读取时,一切正常.
• 即时客户端的DLL(正确地)在库路径中.

• 这是我的类路径中Oracle JDBC JAR的清单:

  Manifest-Version: 1.0  
  Specification-Title:    Oracle JDBC driver classes for use with JDK14  
  Sealed: true  
  Created-By: 1.4.2_14 (Sun Microsystems Inc.)

这是MySQL的配置文件:

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost/test</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">zgy01</property>
    <property name="hibernate.connection.pool_size">100</property>
    <property name="show_sql">false</property>
    <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

    <!-- Mapping files -->
    <mapping resource="model.hbm.xml"/>

  </session-factory>
</hibernate-configuration>

要为SQL Server 2005指定什么？我是这样做的:

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
    <property name="hibernate.connection.url">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
    <property name="hibernate.connection.username">sa</property>
    <property name="hibernate.connection.password">lal</property>
    <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

    <property name="hibernate.connection.pool_size">100</property>        
    <property name="show_sql">false</property>

    <!-- Mapping files -->
    <mapping resource="model.hbm.xml"/>

  </session-factory>
</hibernate-configuration>

更确切地说,我的问题是如何指定我必须连接的数据库？

在MySQL中,我曾经这样做过:

<property name="hibernate.connection.url">jdbc:mysql://localhost/test</property>
