    <p>I have written a <a href="http://code.google.com/p/drools-jca/" rel="noreferrer">JCA resource adapter before</a>.</p> <p>However, now I find myself in a position of having to write one solely to get access to the <code>BootstrapContext</code> and its associated <code>WorkManager</code>, and effectively for no other reason.</p> <p>If I'm reading the specification correctly--and that's my question--it looks like if I want someone to be able to <em>use</em> my resource adapter in a spec-compliant fashion, I still need to implement <code>ManagedConnectionFactory</code>, because it would appear that only user connection factories vended by <code>ManagedConnectionFactory</code> implementations are eligible for injection via the <code>@Resource</code> annotation.</p> <p>Go ahead, read it again; I'll wait. :-)</p> <p>In a perfect world, I'd like to write my <code>ResourceAdapter</code> implementation, annotate it with <code>@Connector</code>, specify all the <code>@ConfigProperty</code> bits, pack it up in a <code>.rar</code> file, and be done with it.</p> <p>However, it looks to me like the specification effectively mandates that all communication between the consumer (a stateless EJB in my case) and the resource adapter module is supposed to be accomplished through a user connection factory.</p> <p>For example, section 6.10.1 says:</p> <blockquote> <p>A resource adapter must provide implementations of the following interfaces:</p> <ul> <li>javax.resource.spi.ManagedConnectionFactory</li> <li>javax.resource.spi.ManagedConnection</li> <li>javax.resource.spi.ManagedConnectionMetaData</li> </ul> </blockquote> <p>But section 18--the section on annotations--doesn't seem to provide for enforcing this in any meaningful way.</p> <p>Is this indeed the case? I suppose it must be, but I'd be curious to hear from people who have put together a 1.6 resource adapter.</p>

    1. COit was long time ago, 2004, when i had to implement a ResourceAdapter, the ManagedConnectionFactory was necessary, I hardly believe anything was changed since.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
