Including the Library in Blackberry 7 Project

To include Tally Authentication Library in your BlackBerry 7 application project

1. Right-click the project in which the authentication library to be used.

2. Click Build Path .

3. Select Configure Build Path .

4. Select Libraries tab.

5. Click Add external JARs .

6. Go to the folder where the Tally Authentication Library is located, select the .jar file, then click Open .

7. Select Order and Export tab.

8. Select .jar file for the Tally Authentication Library, if not already selected, and click OK .

Using the Library in Blackberry 7 Project

1. Create a Runnable object.

2. This Runnable object acts as a callback when the authentication is completed.

Runnable onScreenCloseCallback = new Runnable()


public void run()


String str = "Status : " + TallyLoginInterface. getStatus () +

"\nSessionID : " + TallyLoginInterface. getSessionID () +

"\nTally.NET ID:" + TallyLoginInterface. getTallyNetID () +

"\nError Code: " + TallyLoginInterface. getErrorCode () +

"\nError Desc: " + TallyLoginInterface. getErrorDescription () +

"\nLib version: " + TallyLoginInterface. getLibraryVersion ();

Status. show (str);



3. Create an object of class TallyLoginScreen. Pass the online/offline mode status, and the runnable object in the constructor.

final TallyLoginScreen loginScreen = new TallyLoginScreen(true, onScreenCloseCallback);

4. Set developer mode to true , when application is in testing phase.

TallyLoginInterface. setDeveloperMode ( true );

5. Push the login screen on the current screen. This is done on the main thread.

// run on UI thread

UiApplication. getUiApplication ().invokeLater( new Runnable()


public void run()


UiApplication. getUiApplication ().pushScreen(loginScreen);
