hi all,
I am using the proguard for obfuscation of the Application.AS obfuscator main goal was to decompile and removing the non using classes and including the classes the MIDlet needed.
As expected , i thought that Java.security.SecureRandom will include into the JAR after Obfuscation.
The Java.security.SecureRandom was available in the BouncyCastle, but it did not do anything instead, after running the application it was again giving the application which was little different from the previous one

Please rectify me, if i given any wrong information about obfuscators.
Thanks for your help

Then i came to the MIDlet side
Before the Root certificate was installed into the MEKeytool i am getting the fallowing Exception
javax.microedition.pki.certificateException: certificate from unrecognized entity
1.The root CA was imported into the MEKeyTool with the help of
MEKeytool
2.The certificate was also imported into the MEKeytool with the help of
