title: Unable to change TopLink logging level in GlassFish
body: <p>In a GlassFish 2.1 environment, I am trying to increase the logging level for TopLink... to see the raw SQL being generated.  In the GlassFish Admin Console, I go to:</p>
  
  <pre><code>Configurations -&gt; my-config -&gt; Logger Settings -&gt; "Log Levels" tab
  </code></pre>
  
  <p>The logging level for TopLink is determined by the "Persistence" pulldown menu.  To dump generated SQL to the logs, you increase the level from "SEVERE" to "FINE" (or greater).  </p>
  
  <p>I've done this before on multiple other GlassFish boxes.  However, on THIS box the value always reverts back to "SEVERE" after I click the Save button.  No error message in the Admin Console, and nothing logged that I can find... the new value simply doesn't stick.</p>
  
  <p>The really confusing thing is that I CAN successfully update the logging level for every other category in the system (e.g. "JMS", "JTA", etc).  The problem is specific to the "Persistence" category.</p>
  
  <p>Anyone ever encountered this problem before?  Any thoughts would be appreciated.</p>
