Java StringBuffer Examples

Example #1

 /**
  * Generate an exception message
  *
  * @param aException The Exception object
  * @return A representation of the exception which is appropriate for the client type
  */
 public String generateExceptionMessage(Exception aException) {
   StringBuffer retVal = new StringBuffer("<?xml version=\"1.0\"?>\n");
   retVal.append(
       "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\" \"http://www.wapforum.org/DTD/wml_1.1.xml\">\n");
   retVal.append("<wml>\n");
   retVal.append("<card><p>\n");
   retVal.append("[HTTPEventTranslator Error (");
