The event data can be either manually input, obtained
from an xml Document file or any other binary file.
Firstly, to publish a new event from scratch, select
the desired channel you wish to publish an event onto,
and then right-click on the same node and choose the
'Publish' menu option. This will display a dialog as
shown below where you can construct the event.
In the image above, the data for the event is simply
a string. The properties are added by entering a property
key, a value and a type and then clicking on the 'Add
Property'. Once added, the properties are displayed
in the table at the bottom of the panel. To remove a
property entry, click on the property within the table
view and select the 'Remove Property' menu option. Properties
can also be editted by clicking on the property from
the table and double-clicking in the cell you wish to
change. Once you hit return, the value will be updated
in the table.
To add an XML document as the event data, click on
the 'Open' button in the top right hand cornder of the
dialog, and choose your xml file from the file chooser.
Once opened, the contents of the file will be displayed
within the event data section of the dialog and will
be non-editable. An example of this is shown in the
image below.
To publish the contents of any other file within the
event data, repeat the above steps for XML and select
a non-xml file. The contents of the file will not be
displayed, however the file will be read in binary format
when the 'Publish' button is clicked and published to
the channel. Once again, when a file is selected for
publishing the event data section is non-editable.
Clicking on the 'Clear' button will cancel any file
that has previously been selected and allow you to once
again select a file or manually enter the event data.
In order to duplicate or modify and republish an event
that has already been published to a channel, you must
first of all select the snoop
panel for the channel in question, and snoop the
channel. Once events are displayed in the snoop panel,
select the event you wish to duplicate or modify and
republish from the table of events. Right-clicking on
the event will display a menu with 2 options. The first
option allows you to purge an individual event from
a channel. The second menu option will open the event
publish dialog with the details of the event already
filled in, including the event properties, TTL and persistence.
Properties can be added / removed from the duplicate
event as well as modified. To modify a property, double-click
in the cell of the property you wish to change and then
modifying its contents. With the republish option, you
can also choose to purge the original event from the
channel by checking the 'Purge Original Event' checkbox.
Once the 'Publish' button is clicked, the duplicate
event will be published onto the channel. The number
of publishes depends on the amount entered in the 'Num
Of Publishes' field. The image below shows the publish
dialog for a JMS Message published onto a Nirvana channel.
The publish option is also available for queues. The
republish option is also available from the snoop panel
for queues. |
