title: faultString = "java.lang.NullPointerException : null"
body: <p>i have been pulling my hair for days trying to figure out an error. I have a flex front-end with a locally installed tomcat and a java backend. When i click a button to do some action, i get this error message below</p>
  
  <pre><code>(mx.rpc::Fault)#0
    content = (null)
    errorID = 0
    faultCode = "Server.Processing"
    faultDetail = (null)
    faultString = "java.lang.NullPointerException : null"
    message = "faultCode:Server.Processing faultString:'java.lang.NullPointerException : null' faultDetail:'null'"
    name = "Error"
    rootCause = (Object)#1
      cause = (null)
      localizedMessage = (null)
      message = (null)
      suppressed = (Array)#2
  </code></pre>
  
  <p>any tips on where to go from here? I have tried "google-ing" to no avail
  Thanks</p>
