    Using BouncyCastle in midlet -- Error in console

    I use Eclipse 3.2 which has j2me plug in.

    Previously i asked about encryption in this forum but not much help, so i decided to use bouncy castle encryption package.


    runtime error give me the following error message WHEN i click "send" button in my midlet.

    Code:
    java.lang.NoClassDefFoundError: org/bouncycastle/crypto/PBEParametersGenerator
	at MEMerchantInterface$HelpSelector.commandAction(+721)
	at javax.microedition.lcdui.Display$DisplayAccessor.commandAction(+282)
	at javax.microedition.lcdui.Display$DisplayManagerImpl.commandAction(+10)
	at com.sun.midp.lcdui.DefaultEventHandler.commandEvent(+68)
	at com.sun.midp.lcdui.AutomatedEventHandler.commandEvent(+47)
	at com.sun.midp.lcdui.DefaultEventHandler$QueuedEventHandler.run(+250)
    i dont think there is wrong with the code.
    Is it project setting error ?
    Any idea to fix this NoClassDefFound Error?

    its urgent.
    pls any1 can help ?

    thanks in advance.

      The JVM cannot find the class PBEParametersGe nerator class. If it's in a package make sure you include that package in your project's buid/classpath.

              Obviously depends on the application itself.
              Most applications/games are less than 2mb. You can write a lot of useful midlets that are less than 500kb.
