title: How to know which modules a module depends on in JBoss?
body: <p>How am I supposed to know which dependencies a module need such as the PostgreSQL driver below? If I hadn't Googled it I wouldn't know that. Where am I supposed to find this information?</p>
  
  <pre><code>&lt;module xmlns="urn:jboss:module:1.1" name="org.postgresql"&gt;    
     &lt;resources&gt;    
       &lt;resource-root path="postgresql-9.1-902.jdbc4.jar"/&gt;    
     &lt;/resources&gt;    
     &lt;dependencies&gt;    
       &lt;module name="javax.api"/&gt;   
       &lt;module name="javax.transaction.api"/&gt;
     &lt;/dependencies&gt;    
  &lt;/module&gt;
  </code></pre>
