RE: [Eclipseme-users] Error using Bouncy Castle

[Hunter, K. <kh...@ne...>]

The BouncyCastle mention in the EclipseME help has to do with advanced
key management for signing of MIDlets, not for using encryption within a
MIDlet.  Basically, what is probably happening is that you are compiling
against the JAR file with the BouncyCastle classes in it, but the
classes are not getting included in the MIDlet jar file as part of the
build, and so when the emulator (or device) goes to try to access the
classes, they aren't there.  What you need to do is to have the contents
of the JAR file included in the build.

What you're dealing with is an "application JAR", since it isn't built
into the hardware.

Subject: [Eclipseme-users] Error using Bouncy Castle


Hi. I'm developing an Midlet that deals with cryptography, so, looking
pro an cryptography API for J2ME I found the Bouncy Castle's
lightwheight cypto API. I've downloaded it, put the zip file in the
project's build path, create the encryption class... everything was
normal. But when I run the Midlet, during the loading, before the
application starts, I get an NoClassDefFoundError. The class that the
exception refers is part of the crypto API, CryptoException, for
example, but that is not the only one. If I change the source code, the
class that throws de exception changes too. It seems the VM can't find
the classes, but they are right there where the error's path points. I
looked in many foruns for any help, but it was quite useless. I don't
know what else to do.=20

By the way, in eclipseME help, it says something about BouncyCastle int
the signing the application. I need to set something there?
