Tasklist

public Tasklist(WLPI wlpi,
                javax.swing.table.TableColumnModel columns,
                java.lang.String instanceId)
         throws WorkflowException
Create a Tasklist for the specified workflow instance.

Parameters:
wlpi - The WebLogic Process Integrator server connection to use.
columns - The column model to use.
instanceId - The workflow instance ID.
Method Detail

init

public static void init(java.lang.String jndiFactory,
                        java.lang.String jmsFactory,
                        java.lang.String topicName)
Initialize installation-specific settings. These settings override the hard-coded defaults for the class as described below.

Parameters:
jndiFactory - The fully qualified class name of JNDI initial context factory. The default value is weblogic.jndi.WLInitialContextFactor.
jmsFactory - The JNDI name of the JMS topic connection factory to use. The default value is javax.jms.TopicConnectionFactory.
topicName - The JNDI name of the JMS topic on which the server broadcasts worklist-related update notifications. The default value is com.bea.wlpi.NotifyTopic

exit

public void exit()
Called when the task list is no longer required, in order that the task list may perform cleanup operations. The implementation closes the connection to the JMS notification topic.

getTable

public javax.swing.JTable getTable()
Return the underlying JTable object.

Returns:
The underlying JTable object.

getModel

public javax.swing.table.TableModel getModel()
Return the underlying TableModel object.

Returns:
The underlying TableModel object.

getColumnModel

public javax.swing.table.TableColumnModel getColumnModel()
Return the underlying TableColumnModel object.

Returns:
the underlying TableColumnModel object.

onMessage

public void onMessage(javax.jms.Message msg)
Respond to a JMS task notification message.
Specified by:
onMessage in interface javax.jms.MessageListener

Parameters:
e - The notification message.

refresh

public void refresh()
             throws WorkflowException
Rebuild the contents of this task list.

Throws:
WorkflowException - if an exception prevented the server from returning the list of tasks or if a communications error occurred.

setFilters

public void setFilters(boolean bPending,
                       boolean bDone,
                       boolean bInactive)
Set the list filtering.

Parameters:
bPending - true to include pending tasks.
bDone - true to include completed tasks.
bInactive - true to include inactive tasks.

getCurrentObject

public TaskInfo getCurrentObject()
Return the currently selected task.

Returns:
The currently selected task (or null if no selection).

paint

public void paint(java.awt.Graphics g)
Overridden to implement a workaround for a Swing bug - In JDK 1.2 JTable paints the unused area of a list in the wrong color.

Parameters:
g - The graphics object to use.
Overrides:
paint in class javax.swing.JComponent
