</pre>
<p>Ok, I think we've got crossed wires. You can't deploy a library jar in some "context" outside a deployment. The beans don't get created or anything outside the context of a deployment.</p>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
<p>Another way to think of it is that a library in default/lib with a beans.xml in it works just like a library in WEB-INF/lib.</p>
</blockquote><p>In that case, why the lazy approach wouldn't work?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>From what I can see, if it works just like a library in WEB-INF/lib, it means that we will need to provide a BDA for a lib jar only when Weld requests for one through loadBeanDeploymentArchive, right?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Or, if I'm wrong, do you mean that a BDA for every lib jar with a META-INF/beans.xml should be provided as direct or indirect result of BeanDeploymentArchive.getBeanDeploymentArchives() for every BDA in a Deployment?</p><p>Explaining better, given commos/lib/mylib.jar with the following structure:</p><p>mylib.jar</p><p>  |_</p><p>      META-INF/beans.xml</p><p>  |_</p><p>     whatever classes in here</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Say we create a BDA upfront, let's call it MY_LIB_BDA, and add this BDA to DefalutDomain Classpath. No deployment is created upfront.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Now, say my-ejb.jar with a META-INF/beans.xml file is deployed to deploy dir. We create a Deployment for it, of course, and we create a BDA for it as well. This BDA, called MY_EJB_BDA, belongs to Default Domain Classpath. So, when Weld invokes MY_EJB_BDA.getBDAs(), it should , directly on indirectly (i.e., by walking on the BDA graph structure), reach MY_LIB_BDA?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>This is different from the lazy approach in which you are not required to call loadBeanDeploymentArchive in order to obtain MY_LIB_BDA.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is that what Weld requires us to do?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><blockquote class="jive-quote"><p>Pete Muir wrote:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><blockquote class="jive-quote"><p>Flavia Rainone wrote:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><blockquote class="jive-quote"><p>Ales Justin wrote:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Why the rush? :-)</p><p>If you ask me, I would do it lazily aka on_demand.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Scanning the whole common/lib is gonna be slow,</p><p>and imo, people should not be using libs to deploy Weld components -- simply put them in deploy/.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Or why would you do it upfront?</p></blockquote></blockquote><p>Because the Java EE/CDI specs require it.</p></blockquote><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>BTW, I've read the spec sometime ago.
