How to run Java Card Program in a Simulator

Question

I m Narendra Reddy studying in India and have taken Java Card for my B.E. final year project.
i also acquire knowledge of Whole Java Card Development Life Cycle but i found much more difficulties to implement those ideas into java card.
so, Will you please do me a favour and give me a complete solution if possible with an example.
i also want each step with the commands, from the creation of Class file to the running of prog. in simulator.
it will be very useful for me to head towards my project.
Thank you,

Answer 1

Just for the record,
Since we are looking at different possibilities, there are couple of ways to achieve simulation/testing environment for current Java Card,
1. "The Java Card Workstation Development Environment(JCWDE) tool allows the simulated running of Java Card applet as if it were masked in ROM. It immulates Card environment." Although, as Joe mentioned, it does not support;
- package installation
- applet instance creation
- persistent card state
- firewall
- transactions
- transient array clearing
- remote method invocation
- applet/package deletion
Thus you can use 'jcwde' tool in combination of apdutool to test some
of the Applet behavior(& JCRE) but not all. You have realized this when you tried 'sample' applets.
2. JCDK2.2 also provide c-reference implementation of the Java Card. This(cref) is more robust way to test Applet. Although the catch with this is that Sun does not have SCSL(Community Source Licensing) program for Java Card(alas!) and this means you can not mask your applet into this reference implementation unless you get hold of source code somehow(source licensing is one(costly) way)
3. Buy reader/card and figure out how to install applet for
testing purpose.
4. Buy kit from JC vendor containing reader/software/cards and use it
(costly and hard to find JC2.2 implementation)
1 and 2 are easier but not a real life solution(how many cards with intel/sparc processor anyway?). 3 and 4 are ideal but other way challenging. Yes, probably solution-1 is the right for your purpose.
