Hi All, I'm currently working on $subject. The carbon datasource component registers the JNDIContextManager and DataSourceReader services before initializing datsources using DataSourceManager in an OSGi environment as in [1]. In order to make the carbon datasource component to be used in non-OSGi environment as well, the same services have to be made available using Java SPI before the non-OSGi client makes use of it.
- In the existing implementation the DataSourceReader service can be loaded to non-OSGi environment when initializing datasources using DataSourceManager's initDataSources()[2] which calls loadDataSourceProviders()[3] to load the Service Providers of DataSourceReader SPI. - In order to register JNDIContextManager service in non-OSGi environment, the carbon-jndi component implementation has to be modified. I'm planning to a have separate service provider for JNDIContextManager SPI so that it can be used in non-OSGi environment like we are using the JNDIContextManagerImpl[4] for OSGi environment. Then the particular service provider can be loaded using ServiceLoader and used to do datasource lookup using the Context in non-OSGi environment. Is this the correct approach to acces JNDI service in non-OSGi environment? Please give your suggestions.
