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

Question

I am trying to use WAS liberty rutime profile with eclipse Luna.
My environment:
Window 7
Eclipse luna
Websphere application server tools V8.5 plugin
Websphere liberty profile
My application using spring framework 2.5, and configuration file as below.
<!-- 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>
however when I deploy my application into Liberty Profile (LP). for some reason the class can not be loaded properly.
I can find this class in com.ibm.ws.jdbc_1.0.8.jar file, and this jar file located under {server.home}/lib folder. As I understand this library should be loaded automatically.
The detail of error log:
[ERROR ] SRVE0283E: Exception caught while initializing context: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'oracleLobHandler' defined in ServletContext resource [/WEB-INF/dataAccessContext.xml]: Cannot create inner bean 'org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor#fff379a3' of type [org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor] while setting bean property 'nativeJdbcExtractor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor#fff379a3' defined in ServletContext resource [/WEB-INF/dataAccessContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Could not initialize WebSphereNativeJdbcExtractor because WebSphere API classes are not available: java.lang.ClassNotFoundException: com.ibm.ws.rsadapter.jdbc.WSJdbcConnection

Any ideas on this issue really appreciate. I really got pain with this one.
Many thanks in advance.

Answer 1

com.ibm.ws.jdbc_1.0.8.jar is OSGi bundle, and package you are referring is not exported, so it is not available for application classes.
I assume that you need that to get to the native connection, for that you have two options:
use the JDBC API unwrap() method, like for example connection.unwrap(). See some examples for connection and prepareStatement here
Update to Spring 3.0.5 or higher and use OracleJdbc4NativeJdbcExtractor instead of WebSphereNativeJdbcExtractor (I didn't test that, but should work in theory).

Answer 2

Do you have the jdbc feature enabled in your server.xml? If you have a recent Liberty installation, I would recommend enabling the webProfile-6.0 feature, which is a combination of many commonly used features.

Answer 3

change：
class="org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor" />
to：
class="org.springframework.jdbc.support.nativejdbc.SimpleNativeJdbcExtractor" />
