Lotus Expeditor Forum : How to connect with Derby in Lotus XPD Client For Devices.

Hi All,

I am using Lotus XPD Client For Devices.
When I am trying to connect with Derby through JNDI, I am getting following exception.

An exception occurred when looking up SampleDataSourceDerby
javax.naming.NoInitialContextException: Failed to create InitialContext using factory specified in hashtable {java.naming.factory.initial=com.ibm.pvc.jndi.provider.java.InitialContextFactory}. The stack trace of the root exception is: java.lang.ClassCastException: com.ibm.pvc.jndi.provider.java.InitialContextFactory incompatible with javax.naming.spi.InitialContextFactory

This is my code.

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.pvc.jndi.provider.java.InitialContextFactory");

InitialContext context = new InitialContext(env);

DataSource ds = (DataSource) context.lookup("SampleDataSourceDerby");

This is my plugin.xml extension

<extension
point="com.ibm.pvc.jndi.provider.java.binding">
<binding
jndi-name="SampleDataSourceDerby"
objectFactory-id="com.ibm.pvc.jndi.provider.java.GenericObjectFactory">
</binding>
</extension>
<extension
point="com.ibm.pvc.jndi.provider.java.genericobject">
<object
class="org.apache.derby.jdbc.EmbeddedDataSource"
jndi-name="SampleDataSourceDerby">
<method
name="setDatabaseName">
<method-parameter
type="String"
value="${_workspace}/jndiSampleDatabaseDerby">
</method-parameter>
</method>
</object>
</extension>

What is the wrong in the code? How can I fix this?

Thanks and Regards
