Debugging with Smack
|
|
====================
|
|
|
|
[Back](index.md)
|
|
|
|
Smack includes two built-in debugging consoles that will let you track
|
|
all XML traffic between the client and server. A lite debugger and an
|
|
enhanced debugger contained in `smack-debug.jar`, and a console debugger in `smack-core.jar`.
|
|
|
|
Debugging mode can be enabled in two different ways:
|
|
|
|
1. Add the following line of code **before** creating new connections:
|
|
|
|
`SmackConfiguration.DEBUG = true;`
|
|
|
|
2. Set the Java system property `smack.debugEnabled` to true. The system property can be set on the command line such as:
|
|
|
|
`java -Dsmack.debugEnabled=true SomeApp `
|
|
|
|
If you wish to explicitly disable debug mode in your application, including
|
|
using the command-line parameter, add the following line to your application
|
|
before opening new connections:
|
|
|
|
`SmackConfiguration.DEBUG = false;`
|
|
|
|
Smack uses the following logic to decide the debugger console to use:
|
|
|
|
1. It will first try use the debugger class specified in the Java system property `smack.debuggerClass`. If you need to develop your own debugger, implement the `SmackDebugger` interface and then set the system property on the command line such as:
|
|
|
|
`java -Dsmack.debuggerClass=my.company.com.MyDebugger SomeApp `
|
|
|
|
2. If step 1 fails then Smack will try to use the enhanced debugger. The file `smackx-debug.jar` contains the enhanced debugger. Therefore you will need to place the jar file in the classpath. For situations where space is an issue you may want to only deploy `smack-core.jar` in which case the enhanced and lite debugger won't be available, but only the console debugger.
|
|
|
|
3. The last option if the previous two steps fail is to use the console debugger. The console debugger is a very good option for situations where you need to have low memory footprint.

Enhanced Debugger
|
|
-----------------
|
|
|
|
 When debugging mode is
|
|
enabled, a debug window will appear containing tabs for each new created
|
|
connection. The window will contain the following information:
|
|
|
|
* XMPPConnection tabs -- each tab shows debugging information related to the connection.
|
|
* Smack info tab -- shows information about Smack (e.g. Smack version, installed components, etc.). The connection tab will contain the following information:
|
|
* All Stanzas -- shows sent and received packets information parsed by Smack.
|
|
* Raw Sent Stanzas -- raw XML traffic generated by Smack and sent to the server.
|
|
* Raw Received Stanzas -- raw XML traffic sent by the server to the client.
|
|
* Ad-hoc message -- allows to send ad-hoc packets of any type.
|
|
* Information -- shows connection state and statistics.
|
|
|
|
Lite Debugger
|
|
-------------
|
|
|
|
 When debugging mode is enabled, a
|
|
debug window will appear when each new connection is created. The window will
|
|
contain the following information:
|
|
|
|
* Client Traffic (red text) -- raw XML traffic generated by Smack and sent to the server.
|
|
* Server Traffic (blue text) -- raw XML traffic sent by the server to the client.
|
|
* Interpreted Stanzas (green text) -- shows XML packets from the server as parsed by Smack. Right click on any of the panes to bring up a menu with the choices to copy of the contents to the system clipboard or to clear the contents of the pane.
