    <p>Two projects: the product (project-A) and the auto benchmark project for A (project-B).</p> <p>In B's build file, we need to call A's build file to run the build and bundle-with-app-server process like this:</p> <pre><code>&lt;ant antfile="${build-file-A}" inheritall="false" target="all" /&gt; </code></pre> <p>And, in project B, we have a lot of Ant tasks that output messages using java.util.logging (The JDK Logging Framework).</p> <p><strong>The problem is, after that line, all the jdk logger outputs disappear.</strong></p> <p>With debugging, I find that, during the initialzation of project A's build file, a staticly defined thing in project A will run <code>LogManager.readConfiguration(InputStream)</code>, which loads a config file that only contains the logger configuration of a single class.</p> <p>And during <code>readConfiguration</code>, <code>LogManager.reset()</code> will be called; <strong>during <code>reset</code>, each handler of each logger will be removed</strong>. As <code>&lt;ant&gt;</code> will load the target build file to the same process of the caller, all the handlers will be removed.</p> <p>So, except the configurated one, every other class that use jdk logger can't output messages due to lack of output handler.</p> <p><strong>My question is:</strong></p> <p>Is there any way to solve this problem, other than:</p> <ol> <li>use <code>&lt;exec&gt;</code> to run project A's build file;</li> <li>write a task to run <code>readConfiguration()</code> to restore the default JDK logging settings from the default configuration file after the <code>&lt;ant&gt;</code> call.</li> <li>Use ant's own logging framework (Task.log(), etc).</li> </ol> <p>Please note that I can't modify project A to prevent the problem.</p>

    2. CO@fge Output of jdk logger doesn't show up in the console -- the task is successfully executed, but no output. As I said, the ConsoleHandler of the root logger is removed when `readConfiguration(InputStream)`, which formats and outputs the logging message.

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.
