title: How to make Mule 3 display full stack traces
body: <p>I had an exception where I got this shortened trace:</p>
  
  <pre><code>Root Exception stack trace:
  java.sql.SQLException: Invalid column name
      at oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3677)
      at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:2749)
      at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:494)
      + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)
  </code></pre>
  
  <p>I then put this in "<strong><code>log4j.properties</code></strong>" and it didn't help:</p>
  
  <pre><code>log4j.logger.org.mule=DEBUG
  </code></pre>
  
  <p>I also failed with the second suggestion (and I suspect I'm not doing it right):</p>
  
  <pre><code>$ ./mule -Dmule.verbose.exceptions=true
  </code></pre>
