Error when using BouncyCastle to create RSA crypto in midlet

[phungnguyen]

hi all,

i created obfuscated package successfully with Proguard4.4 and clcd_classes.zip of BC 1.45. But when i run project from JAD url: {project name}/bin/deployed then i alway get error:

Uncaught exception java/lang/NoClassDefFoundError: org/bouncycastle/crypto/KeyGenerationParameters, or symmetricCipherKeyPair

i'm using eclipseME and i don't know that where step is incorrect?
pls help me, see picture below to detail




thks and best regards

Go to the project's build-path configuration. Look in the "order and export" tab, and make sure that the Bouncy Castle libraries are set to "export" (ticked).

thanks Graham,

i read many topic of this discussion but i haven't found solution to fix this problem.

i went to project's build-path configuration and ticked on BC lib and then i could not create obfuscated package with error:

Errors occurred during the build.
Errors running builder 'Preverification' on project.
org.eclipse.jdt.internal.core.JavaModel.getTarget(Lorg/eclipse/core/resources/IContainer;Lorg/eclipse/core/runtime/IPath;Z)Ljava/lang/Object;

When i did not tick on BC lib then i created obfuscated package successfully. I don't know what?

My use specified arguments: -dontusemixedcaseclassnames -dontnote -dontoptimize -defaultpackage '' -libraryjars 'C:\crypto-145\crypto-145\zips\cldc_classes'

(srr for my bad english)
thks and best regards

Don't specify your own obfuscation arguments. Allow it to use its defaults.

Graham.

thank Graham,

yes, i will do it,

and i found solution to fix my problem.
- first: i have to check on BC lib of project's build-path configuration
- second: update eclipseME plugin version 1.8 for eclipse IDE version 3.4 with link: http://eclipseme.org/testversions

only that, very simple but i used much time to fix it, and i saw many people in orther forums get similar problem.
i hope they would see this topic and fix their error successfully.

thanks and best regards
