If you're talking some every day generic Java application running outside of the container, then you're out of luck. Effectively you would need to configure your own JNDI implementation, with it's own configure connection pool, etc.

However, you can write Java EE "standalone" applications. These are applications that run within the Java EE application client. Basically, it's an app that is deployed and packaged, but then executed using a launcher that's provided by your Java EE container.

When running within an application client environment, all of the resources of the app server (connection pools, EJBs, queues, etc.) are available to your app just like they would be if the code were deployed within the app server.

<a href="http://java.sun.com/j2ee/1.4/docs/tutorial/doc/EJB4.html#wp79891" rel="nofollow noreferrer">Here</a> is some tutorial documentation for Sun App Server 8.2, which is a J2EE 1.4 container.

If it's possible I'd strongly suggest upgrading to Glassfish v2.1, just a more modern, better all around server that should deploy your apps just fine as is, since it's a descendant of 8.2.

What you want is an <a href="http://java.sun.com/developer/technicalArticles/J2EE/appclient/" rel="nofollow noreferrer">Application Client</a>

Alternatively you could establish a plain JDBC connection from your standalone client which might be easier to create - but you'll have to configure the connection details in the client and can not reuse the settings from your application server.

blocks|key|3267771|text|我被完全相同的问题卡住了。我写了一个小教程。基本上，您必须创建自己的DataSource对象实现，并将它们添加到您自己的自定义初始上下文中。这里有一些源码示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3267772|Running+Beans+Locally+that+use+Application+Server+Data+Sources|offset|length|3267773|entityMap|0|LINK|mutability|MUTABLE|url|http://penguindreams.org/blog/running-beans-that-use-application-server-datasources-locally/^0|0|0|1Q|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I got stuck on this exact same problem. I wrote a small tutorial. Basically you have to create your own implementation of the DataSource objects and add them to your own custom initial context. There are source examples here:

blocks|key|310550|text|这对你来说可能有点晚了，但我已经使用Simple-JNDI+library很多年了，这正是你提到的目的。我不确定它是否具有您可能需要的所有选项，但对于我的命令行实用程序来说，它已经足够了。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|310551|entityMap|0|LINK|mutability|MUTABLE|url|https://code.google.com/p/osjava/wiki/SimpleJNDI^0|I|J|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

This might be a bit late for you but I have used the <a href="https://code.google.com/p/osjava/wiki/SimpleJNDI" rel="nofollow noreferrer">Simple-JNDI library</a> for many years for the exact purpose you mention. I'm not sure if it has all the options you may need but it sufficed for my command line utilities.

blocks|key|312580|text|尝试使用Simple-JNDI。它为您提供了JNDI服务的内存实现，并允许您使用属性文件中定义的对象填充JNDI环境。还支持加载在文件中配置的数据源或连接池。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|312581|要获得一个连接池，你必须创建一个类似这样的文件：|312582|type=javax.sql.DataSource

Try Simple-JNDI. It gives you an in-memory implementation of a JNDI Service and allows you to populate the JNDI environment with objects defined in property files. There is also support for loading datasources or connection pools configured in a file.

To get a connection pool you have to create a file like this:

<pre><code>type=javax.sql.DataSource
driver=com.sybase.jdbc3.jdbc.SybDriver
pool=myDataSource
url=jdbc:sybase:Tds:servername:5000
user=user
password=password
</code></pre>

In your application you can access the pool via

<pre><code>Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("path/to/your/connectionPool");
</code></pre>

I haved used Simple-JNDI for this purpose for years now. But it is not under active development anymore. Because I found some issues concerning shared contexts (especially using datasources), I decided to branch the original project and to add some new features. Now there is a 0.13.0. You can find more about it at <a href="https://github.com/h-thurow/Simple-JNDI" rel="nofollow noreferrer">https://github.com/h-thurow/Simple-JNDI</a>.

I have the following environment set up:

<ul>
<li>Java 1.5</li>
<li>Sun Application Server 8.2</li>
<li>Oracle 10 XE</li>
<li>Struts 2</li>
<li>Hibernate</li>
</ul>

I'm interested to know how I can write code for a Java client (i.e. outside of a web application) that can reference the JNDI datasource provided by the application server.

The ports for the Sun Application Server are all at their defaults. There is a JNDI datasource named jdbc/xxxx in the server configuration, but I noticed that the Hibernate configuration for the web application uses the name java:comp/env/jdbc/xxxx instead.

Most of the examples I've seen so far involve code like

<pre><code>Context ctx = new InitialContext();
ctx.lookup("jdbc/xxxx");
</code></pre>

But it seems I'm either using the wrong JNDI name, or I need to configure a jndi.properties or other configuration file to correctly point to a listener? I have appserv-rt.jar from the Sun Application Server which has a jndi.properties inside of it, but it does not seem to help.

There's a similar question here, but it doesn't give any code / refers to having iBatis obtain the JNDI Datasource automatically: <a href="https://stackoverflow.com/questions/39053/accessing-datasource-from-outside-a-web-container-through-jndi">Accessing Datasource from Outside A Web Container (through JNDI)</a>

How do I lookup a JNDI Datasource from outside a web container?
