    <p>I have a problem providing some third party librarys (JAR-files) I am using when deploying my dynamic web application with Tomcat 6 and Eclipse.</p> <p><em>Please note that I -do know- how to do this in a setup, where the web application project -directly- depends on those JARs.</em></p> <p>However, in my setup, I have two Eclipse projects:</p> <ul> <li><strong>core</strong> is a class library and depends on, lets say, <code>a.jar</code>.</li> <li><strong>web</strong> is the web application and depends on <strong>core</strong>.</li> </ul> <p>In the project settings of <strong>web</strong>, in the <em>Deployment Assembly</em> category, I have added <strong>core</strong>, so Eclipse (or Tomcat - I'm not quite sure who the responsible actor here is) is putting <code>core.jar</code> into the <code>libs</code> directory of my web application.</p> <p>The problem is: When I try out the web application, a <code>NoClassDefFoundError</code> is thrown when <strong>core</strong> accesses classes from <code>a.jar</code>. What am I supposed to do about this? I don't think that putting <code>a.jar</code> into the <em>Deployment Assembly</em> settings page of my web application is the right solution, since it should be of no relevance to the <strong>web</strong> project, what the <strong>core</strong> project depends on.</p> <p>Basically, I am looking for a way to configure Eclipse (Tomcat?) to 'embed' the dependencies of <strong>core</strong> into <code>core.jar</code>. The problem about this is, that <code>core.jar</code> is generated automatically, when I deploy my <strong>web</strong> project.</p> <p>Help is very appreciated. Thanks in advance!</p>

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.
