[gemini-dev] How to register a data source instance with JNDI

Hi,

 

I made my first steps with Gemini DBAccess to register oracle data sources in an OSGi environment. And it works fine. Thanks for that.

Looking for a JNDI solution I found your project Gemini Naming. I analyzed the code and be aware that the Activator registers all the required components (even the OSGiURLContextFactory), to be able to look up for a JNDI-registered data source instance via a JNDI client as described in http://wiki.eclipse.org/Gemini/Naming/Documentation/JNDI_Clients.

What I´m not aware is how to register a data source instance with JNDI. How do I register a created data source instance with JNDI to be able to get that data source from another bundle.

I found in http://docs.oracle.com/cd/B28359_01/java.111/b31224/urls.htm#i1063832 the snippet:

Context ctx = new InitialContext();

ctx.bind("jdbc/sampledb", ods);

I tried with the following snippet, convinced that gemini naming registered every required components for that:

ServiceReference serviceReference = ctx.getServiceReference("org.osgi.service.jndi.JNDIContextManager");

JNDIContextManager contextManager = (JNDIContextManager) ctx.getService(serviceReference);

Context initialContext = contextManager.newInitialContext();

initialContext.bind(iDataSourceProps.getJNDIName(), createDataSource(iDataSourceProps));

But I received a javax.naming.NoInitialContextException.

Therefore I ask for the correct way how to do this.

Thanks a lot in advance.

 

Mit freundlichen Grüßen / Kind regards / Cordialmente
