This method is required when the HardGC flag is false. When the HardGC flag is false, memory used by this object is not recovered during normal JVM garbage collection. As a result, you must call the release method when you are finished with this object.
It is safe to call the release method when the HardGC flag is true; in this case no action is taken.
Note: If you want to release an array of objects, you must iterate through the array and call this method on each object.


public static void release ( );


There are no parameters for this method.


Nothing. The release method does not throw an exception if an error occurs.


   public short checkSignature(FormNodeP theSignatureNode, Certificate 
   Signature theSignatureObject;
   String theSecret;
   String signerCommonName;
   BooleanHolder encodedData;
   IntHolder theStatus;
   short validation;
      theSignatureObject = theSignatureNode.getSignature();
      encodedData = new BooleanHolder();
      if ((signerCommonName = theSignatureObject.getDataByPath(
         "HMACSigner: CN", false, encodedData)) == null)
         throw new UWIException("Could not determine signer's name.");
      /* Include external code that matches the signer's identity to a shared 
         secret, and sets theSecret to match.  This is most likely a
         database lookup. */
      theStatus = new IntHolder();
      validation = theSignatureNode.validateHMACWithSecret(theSecret, 
         theServerCert, theStatus);
      /* Check the status in case the process required user input. */
      if (theStatus.value != SecurityUserStatusType.SUSTATUS_OK)
         throw new UWIException("Validation required user input.");
