SystemException on installing applet #125

Open behnejad opened 6 years ago

behnejad commented 6 years ago

Hi. i am getting this SystemException when my applet class is going to install. Exception in thread "main" javacard.framework.SystemException at javacard.framework.SystemException.throwIt(Unknown Source) at com.licel.jcardsim.base.Simulator.createApplet(Simulator.java:179) at com.licel.jcardsim.base.Simulator.installApplet(Simulator.java:219) at com.licel.jcardsim.base.Simulator.installApplet(Simulator.java:195)

my applet works on real java card (both version 2.2 and 3) but it failed to install on simulation. does it come from my applet or something else?

Hi @liyanhrxy Successfully passed the installApplet function call while previously got stuck on the same System Exception. In my case the applet itself causes this by invoking a crypto function (Signature.getInstance(....)) with a non-existing (I mean on simulator's JCVM) parameter's value. So I had to add additional handling just for the jcardsim And @behnejad probably had the same issue. Usually smartcards have their own HW blocks and proprietary JC libs implementations. Anyway, thanks @licel for his work.
