[resolved] Oracle DB access via Karaf

[Anonymous]

We are trying to configure the oracle database access through karaf.

Below is the link that we used.
https://github.com/cschneider/Karaf-Tutorial/blob/master/db/datasource/datasource-oracle.xml
The blueprint for datasource-oracle.xml for ojdbc6.jar:
<blueprint xmlns=" http://www.osgi.org/xmlns/blueprint/v1.0.0">
<bean id="dataSource" class="oracle.jdbc.OracleDriver">
<property name="url" value="jdbc racle:thin:@10.75.38.124:1521 20KSTN"/>
<property name="user" value="workflow_app"/>
<property name="password" value="pass_w0rd"/>
</bean>

<service interface="javax.sql.DataSource" ref="dataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jdbc/oracleds"/>
</service-properties>
</service>
</blueprint>

However, in karaf list we get the following error.
In Karaf list:
wrap_mvn_ojdbc_ojdbc_11.2.0.2.0 (0)
datasource-oracle.xml (0.0.0)

You are using the wrong class from Oracle. Try to use oracle.jdbc.pool.OracleDataSource instead of OracleDriver.

The result was the same using oracle.jdbc.pool.OracleDataSource.
Thanks.

I suspect you still inadvertently use the old blueprint file with the wrong class. Bundles (and the blueprint file is seen as bundle by the OSGi container) are cached in the data directory. Make sure to explicitly uninstall the datasource-oracle.xml bunlde before installing the new one. Removing bundles or blueprint configurations from the deploy folder does not lead to uninstallation of the bundle.
oracle.jdbc.pool.OracleDataSource is definetly the way to go.

I just checked on my karaf and you are right. The problem is that the URL property has to be in uppercase. I just corrected the git datasource file. The bean should now look like this:
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="jdbc racle:thin:@localhost:1521 rcl"/>
<property name="user" value="test"/>
<property name="password" value="test"/>
</bean>
Does this work for you?

Excellent.... It works. Thanks a lot...
