Question

我正在尝试使用eclipse Luna的WAS自由rutime配置文件。

我的环境：

Window 7

Eclipse luna

Websphere应用服务器工具V8.5插件

Websphere liberty profile

我的应用程序使用spring framework 2.5，配置文件如下。

<!-- For Oracle and Websphere; you need to use this lob handler definition instead of defaultLobHandler. Because of differences in Oracle's Blob objects. -->
<bean id="oracleLobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler" >
    <property name="nativeJdbcExtractor" >
        <bean class="org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor"/>
    </property>
</bean>

然而，当我将我的应用程序部署到Liberty Profile（LP）时。由于某种原因，该课程无法正确加载。

我可以在com.ibm.ws.jdbc_1.0.8.jar文件中找到这个类，这个jar文件位于{server.home} / lib文件夹下。据我所知，这个库应该自动加载。

错误日志的详细信息：

关于这个问题的任何想法都非常感谢。我真的很痛苦。

非常感谢提前。

Answer 1

com.ibm.ws.jdbc_1.0.8.jar是OSGi包，您引用的包不会被导出，因此它不适用于应用程序类。

我认为您需要这样才能获得本机连接，因为您有两种选择：

使用JDBC API unwrap()方法，例如connection.unwrap()。请参阅一些连接示例和prepareStatement here
更新到Spring 3.0.5或更高版本并使用OracleJdbc4NativeJdbcExtractor代替WebSphereNativeJdbcExtractor（我没有对此进行测试，但理论上应该有效）。

Answer 2

您是否在server.xml中启用了jdbc功能？如果您有最近的Liberty安装，我建议启用webProfile-6.0功能，该功能是许多常用功能的组合。

Answer 3

变化： class =“org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor”/＆gt;

于： class =“org.springframework.jdbc.support.nativejdbc.SimpleNativeJdbcExtractor”/＆gt;

java.lang.ClassNotFoundException：com.ibm.ws.rsadapter.jdbc.WSJdbcConnection
