title: Weblogic 10.3.5 Web app startup error
body: <p>I'm trying to deploy a web app into Weblogic 10.3.5 and when I try to start the application I'm getting the following error:</p>
  
  <pre><code>####&lt;Oct 29, 2012 5:27:12 AM PDT&gt; &lt;Warning&gt; &lt;HTTP&gt; &lt;ip-0A2E9E72&gt; &lt;AdminServer&gt; &lt;[STANDBY] ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)'&gt; 
  &lt;&lt;WLS Kernel&gt;&gt; &lt;&gt; &lt;&gt; &lt;1351513632838&gt; &lt;BEA-101162&gt; 
  &lt;User defined listener artemispm.web.ui.gwt.server.A7WebStartupListener failed: java.lang.NullPointerException.
  java.lang.NullPointerException

  at java.util.Properties.setProperty(Properties.java:143)
  at java.lang.System.setProperty(System.java:729)
  </code></pre>
  
  <p>The error above is caused by the following code excerpt which is part of a ServiceContextListener class implementation:</p>
  
  <pre><code>System.setProperty(A7WebConstants.PROP_OUTPUT_DIR_PATH, outputDirPath);
  </code></pre>
  
  <p>The outputDirPath variable is not null so does any one know what is going down here? I'm using JDK6 and the application runs pretty fine on Tomcat 6 and 7 as well. Also, I haven't changed any configurations in web.xml file.</p>
  
  <p>**UPDATED:</p>
  
  <p>I just have noticed that when I try to deploy my app I get this error, before the above one:</p>
  
  <pre><code>####&lt;Oct 29, 2012 7:03:25 AM PDT&gt; &lt;Error&gt; &lt;Console&gt; &lt;ip-0A2E9E72&gt; &lt;AdminServer&gt; &lt;[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'&gt; &lt;weblogic&gt; &lt;&gt; &lt;9fceb15ac10fa447:5dceb4c5:13aac5c55aa:-7ff7-0000000000000005&gt; &lt;1351519405088&gt; &lt;BEA-240003&gt; &lt;Console encountered the following error java.lang.IllegalArgumentException: Getting Deployment configuration...
