public class LoggingClient
extends javax.swing.JRootPane
implements ACSRemoteLogListener, ACSLogConnectionListener, ACSRemoteErrorListener, MessageWidget.MessageWidgetListener

Defines a JRootPane Application LoggingClient for displaying event logs received through the CORBA protocol for the purpose of monitoring and reviewing of the logs. It contains of a JScrollPane scrollLogTable for the logs and a LogEntryTable logEntryTable for displaying the status as well as a JPanel ivjJFrameContentPane. Multiple listeners handle user's input. Based on the current code and our understanding of it one could describe the information flow as follows. User's input triggers events which are caught by the listeners attached to each one of the available GUI object representations defined in the LoggingClient class. Independent of that there are messages available at the logging system generated by the other services running in the framework. These messages are parsed by the ACSStructuredPushConsumer class using the SAX parser and are then passed on using the LogTableDataModel's appendLog method for putting the logs to the log table. In particular, we are interested in the saving and loading of files to be implemented by the LoggingClient. While saveFile and loadFromFile are defined in LogTabledataModel, the LogImportTask file makes use of the the LogTabledataModel's appendLog method as well. The use of the DocumentBuilderFactory in the LogImportTask defines a way for transforming a DOM tree into XML.

An important issue is the format of the Log Entry Message produced by the Logging Service. Certain characters ('<', '>', '&', ''', '"') need to be escaped because they delineate markup data from character data and cause the following exception in ACSLogParserDOM class: org.xml.sax.SAXParseException: The content beginning with '<' is not legal markup. One solution is replacing the character with the appropriate html substitute <. Another solution is keeping it in a CDATA section: <[!CDATA[the log entry message]]>.

The panel can be instantiated: - by LogFrame - as an EXEC plugin

enableFiltersWidgets

public void enableFiltersWidgets(boolean enable)

Enable/disable the filter menu item and the filter button in the tool bar.

Calling this method overwrites the setting of the tool bar's "filtersBtn" via LogToolBar.setEnabled(boolean). This feature is needed to disable this button when jlog runs inside the OMC, because there we get calls to LogToolBar#setEnabled(true) for every table update, menu opening etc.

Parameters:

enable - true enables the widgets

Specified by:

errorReceived in interface ACSRemoteErrorListener

Parameters:

xml - That string that caused the error

See Also:

ACSRemoteErrorListener

showErrorMessage

public void showErrorMessage(java.lang.String shortDescription,
                             java.lang.Throwable t)

Show an error in the error panel displayed on top of the table of logs.

Implementation notes:

1. this method shows the error widget and set the glass pane so that it will catch all the events but those directed the error widget's ACK button. What this method does not do, is to make the glass pane visible. This is done by the connection listener methods. If, in future, you want to show the glass pane even here, you should do it explicitly.
2. when the connection with ACS is again available, the acsLogConnEstablished programmatically pushes the ACS button of the error widget causing the widget to disappear without any intervention from the user. This is very useful when the auto reconnect option is enabled. However, note that if showErrorMessage is used for notifying other abnormal situations then a different strategy must be used to avoid the error widget to disappear at the wrong time (i.e. without the user acknowledge the problem).

showErrorMessage prints a message in the stderr too in case the glass pane can't be made visible (for example if an error occurs while building the LoggingClient object).

Parameters:

shortDescription - The description of the error

t - The throwable that caused the error (can be null).

errorAcknowledged

public void errorAcknowledged()

When the user acknowledges the message, we enable the glass pane to forward all the messages to the content pane.

This method is executed when the user presses over the ACK button of the error widget and remove the constraints on the glass pane.

Specified by:

errorAcknowledged in interface MessageWidget.MessageWidgetListener

See Also:

showErrorMessage for further implementation details

getViewCoordinator

public ViewCoordinator getViewCoordinator()
