1 -  * This type was generated by a SmartGuide.
1 -  * 
1 -  * Defines a JFrame Application LoggingClient for displaying event logs 
1 -  * received through the CORBA protocol for the purpose of monitoring and 
1 -  * reviewing of the logs. It contains of a JScrollPane ivjLogTable for the 
1 -  * logs and a LogEntryTable ivjScrollPaneTable for displaying the status 
1 -  * as well as a JPanel ivjJFrameContentPane. Multiple listeners handle 
1 -  * user's input. 
1 -  * Based on the current code and our understanding of it one could describe
1 -  * the information flow as follows. User's input triggers events which are 
1 -  * caught by the listeners attached to each one of the available GUI object
1 -  * representations defined in the LoggingClient class. 
1 -  * Independent of that there are messages available at the logging system 
1 -  * generated by the other services running in the framework. These messages are
1 -  * parsed by the ACSStructuredPushConsumer class using the SAX parser and are
1 -  * then passed on using the LogTableDataModel's appendLog method for outputing
1 -  * the logs to the log table. 
1 -  * In particular, we are interested in the saving and loading of files to be 
1 -  * implemented by the LoggingClient. While saveFile and loadFromFile are defined 
1 -  * in LogTabledataModel, the LogImportTask file makes use of the 
1 -  * the LogTabledataModel's appendLog method as well. The use of the DocumentBuilderFactory 
1 -  * in the LogImportTask defines a way for transforming a DOM tree into XML. 
1 -  * 
1 -  * An important issue is the format of the Log Entry Message produced by the Logging 
1 -  * Service. Certain characters ('<', '>', '&', ''', '"') need to be escaped 
1 -  * because they delineate markup data from character data and cause the following exception 
1 -  * in ACSLogParser class: 
1 -  * org.xml.sax.SAXParseException: The content beginning with '<'
1 -  * is not legal markup. 
1 -  * One solution is replacing the character with the appropriate html substitute &lt;.
1 -  * Another solution is keeping it in a CDATA section: <[!CDATA[the log entry message]]>.
