Looks like you are missing Context envCtx = (Context) initCtx.lookup("java:comp/env");
JNDI lookup should be done like this:

// Obtain our environment naming context
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");

// Look up our data source
DataSource ds = (DataSource) envCtx.lookup("jdbc/EmployeeDB");

// Allocate and use a connection from the pool
Connection conn = ds.getConnection();
