title: Can't compile a GWT web application on Netbeans 6.9, throws error about build-gwt.xml
body: <p>Just two days ago, I switched from Windows 7, and now run a Ubuntu 10.10 system, no multi-boot.</p>
  
  <p>Anyway, after installing Netbeans, JDK, Tomcat and GWT4NB, I create an empty GWT project and hit "compile" to make sure everything works well...</p>
  
  <p>This is what I get:</p>
  
  <pre><code>/home/loupax/NetBeansProjects/WebApplication2/nbproject/build-gwt.xml:138: The following error occurred while executing this line:
  /home/loupax/NetBeansProjects/WebApplication2/nbproject/build-gwt.xml:166: Java returned: 1
  BUILD FAILED (total time: 0 seconds)
  
  Line 138:  &lt;antcall target="do-gwt-compile-15" /&gt;
  Line 166: jvmargs="${gwt.compiler.jvmargs}"&gt;
  </code></pre>
  
  <p>Any ideas of what should I do?
  Thanks!</p>
