/**
|
||||
* Simple implementation of a JNDI naming context builder.
|
||||
*
|
||||
* <p>Mainly targeted at test environments, where each test case can
|
||||
* configure JNDI appropriately, so that <code>new InitialContext()</code>
|
||||
* will expose the required objects. Also usable for standalone applications,
|
||||
* e.g. for binding a JDBC DataSource to a well-known JNDI location, to be
|
||||
* able to use traditional J2EE data access code outside of a J2EE container.
|
||||
*
|
||||
* <p>There are various choices for DataSource implementations:
|
||||
* <ul>
|
||||
* <li>SingleConnectionDataSource (using the same Connection for all getConnection calls);
|
||||
* <li>DriverManagerDataSource (creating a new Connection on each getConnection call);
|
||||
* <li>Apache's Jakarta Commons DBCP offers BasicDataSource (a real pool).
|
||||
* </ul>
|
||||
*
|
||||
* <p>Typical usage in bootstrap code:
|
||||
*
|
||||
* <pre class="code">
|
||||
* SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
|
||||
* DataSource ds = new DriverManagerDataSource(...);
|
||||
* builder.bind("java:comp/env/jdbc/myds", ds);
|
||||
* builder.activate();</pre>
|
||||
*
|
||||
* Note that it's impossible to activate multiple builders within the same JVM,
|
||||
* due to JNDI restrictions. Thus to configure a fresh builder repeatedly, use
|
||||
* the following code to get a reference to either an already activated builder
|
||||
* or a newly activated one:
|
||||
*
|
||||
* <pre class="code">
|
||||
* SimpleNamingContextBuilder builder = SimpleNamingContextBuilder.emptyActivatedContextBuilder();
|
||||
* DataSource ds = new DriverManagerDataSource(...);
|
||||
* builder.bind("java:comp/env/jdbc/myds", ds);</pre>
|
||||
*
|
||||
* Note that you <i>should not</i> call <code>activate()</code> on a builder from
|
||||
* this factory method, as there will already be an activated one in any case.
|
||||
*
|
||||
* <p>An instance of this class is only necessary at setup time.
|
||||
* An application does not need to keep a reference to it after activation.
