How to register a DataSource in JNDI

Question

I'm having a great deal of difficulty getting JNDI to work properly.
I'm attempting to use Quartz scheduler in a test program using a Derby database to store the scheduled events. In order to do this, I must pass Quartz the JNDI name of the data source for the database connection.
Unfortunately, virtually all of the documentation I've been able to find gives half of the story, and then says something to the like of "system properties required to actually make this work not shown". GRR!
I did come across some code for setting up a service provider, but I get even more errors when I try to set up a data source:
     Hashtable<Object, Object> env = new Hashtable<Object, Object>();
     // env.put(Context.INITIAL_CONTEXT_FACTORY, "com.smardec.jndi.mirror.MirrorInitialCtxFactory");
     env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.FSContextFactory");
     env.put(Context.PROVIDER_URL, "file:/");
     Context context = new javax.naming.InitialContext(env);
     org.apache.derby.jdbc.ClientDataSource40 dataSource = new org.apache.derby.jdbc.ClientDataSource40();
     dataSource.setServerName("my_derby_database_server");
     dataSource.setDatabaseName("my_derby_database_name");
     context.bind("jdbc/quartzdb", dataSource);If I try to use MirrorJNDI, I get the following error:
javax.naming.InvalidNameException: Cannot handle all components
at com.smardec.jndi.mirror.MirrorCtx.getParsedName(MirrorCtx.java:90)
at com.smardec.jndi.mirror.MirrorCtx.bind(MirrorCtx.java:133)
at com.smardec.jndi.mirror.MirrorCtx.bind(MirrorCtx.java:160)
at javax.naming.InitialContext.bind(InitialContext.java:400)
If I try using FSContextFactory, I get the following error:
javax.naming.OperationNotSupportedException: can't bind arbitrary objects in an FSContext
at com.sun.jndi.fscontext.FSContext.bind(FSContext.java:180)
at com.sun.jndi.fscontext.FSContext.bind(FSContext.java:167)
at javax.naming.InitialContext.bind(InitialContext.java:400)
Is there some simple way to just create and register a DataSource so that Quartz can find and use it?

Hi Karl
unfortunally i think that you can not store the org.apache.derby.jdbc.ClientDataSource40 object in the file system
the problem is related to the implementation of the JNDI for the File System
reading the officila SUN documentation you can find that
"Java objects can be stored in the file system under the following conditions:"
The initial factory is RefFSContextFactory (not FSContextFactory)
The object is of type java.naming.Reference or implements java.naming.Referenceable
anyway i post the official link of the official SUN documentation:
for the SUM JNDI home page
http://java.sun.com/javase/technologies/core/jndi/index.jsp
hire the SUN SPI
http://java.sun.com/products/jndi/serviceproviders.html
where you have downloaded the jar for the File System SPI (check the doc folder... there is an exmple how to put and get objects in the file system)
Bye
