me is the database name // if create is true, create the database if necessary javax.sql.DataSource makeDataSource (String dbname, boolean create) throws Throwable { EmbeddedDataSource40 ds = new EmbeddedDataSource40(); ds.setDatabaseName(dbname); if (create) ds.setCreateDatabase("create"); return ds; }

Example of setting properties thru reflection. This code is typically generated by tools or written by a system integrator:

 javax.sql.DataSource makeDataSource(String dbname)  throws Throwable  { Class[] parameter = new Class[1]; parameter[0] = dbname.getClass(); DataSource ds =  new EmbeddedDataSource40(); Class cl = ds.getClass(); Method setName = cl.getMethod("setDatabaseName", parameter); Object[] arg = new Object[1]; arg[0] = dbname; setName.invoke(ds, arg); return ds; }

Example on how to register a data source object with a JNDI naming service.

 DataSource ds = makeDataSource("mydb"); Context ctx = new InitialContext(); ctx.bind("jdbc/MyDB", ds);

Example on how to retrieve a data source object from a JNDI naming service.

 Context ctx = new InitialContext(); DataSource ds = (DataSource)ctx.lookup("jdbc/MyDB");


    DataSource  ds;


    if ( usingEmbeddedClient() )
    {
      EmbeddedDataSource40 eds = new EmbeddedDataSource40 ();

      eds.setDatabaseName ("embedquerydb");
      eds.setCreateDatabase ("create");


      ds = eds;
    }
