Re: OpenSSL use into java applet

[Bhupendra K Joshi]

Hi Angel,

 

JNI and web-loaded Applets are incompatible, even if you sign them or jump through incredible hoops. You must use a Signed Applet to install an second signed one on the client's local hard disk, and then use that second Applet to do your JNI work. Even then loadLibrary is unreliable.

 

I can't gurantee that but it may work for you.

Hello:

I use various jar files because I use a jar with the code of my program, and
others jar files from libraries that my code use.

My html code is:
archive="parteI.jar,base-core.jar,base-opt.jar,pcsc-wrapper-2.0.jar,referenc
e-services.jar"
width=325 height=325>


The file "parteI.jar" is my code, and the others are from OpenCard.

I have signed this jar files to allow the execution and not have security
restrictions.

What do you suggest me?

Regards.

This sounds as a security restriction related the use of an applet.
This can be come around by puting in an UNIQUE jar file
all the programs needed to run the applet.
