    Using BouncyCastle J2ME encryption package in j2me midlet

    I use Eclipse 3.2 which has j2me plug in.

    I use bouncycastle encryption package to encrypt a string that is going to SMS out to my company gateway.

    It runs well until i click "send" command, the error shown in console which is:
    Code:
    java.lang.NoClassDefFoundError: org/bouncycastle/crypto/PBEParametersGenerator
	at MyApplication$HelpSelector.commandAction(+721)
	at javax.microedition.lcdui.Display$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)
    Why it says NoClassDefFound Error ?
    How to fix this error ?

    any1 can help?
    please its urgent.

    thanks alot..

      I think that comes from the class not being on the classpath or some other configuration error with java. Try asking this question in the Java forum to see what it comes up with.

          If bouncycastle package is a .jar then you need to add it to your project's build path.
