Program compiles, but does not run

Hi,

I am new to XCode, and I am trying to port a Java application from the PC to the Mac. The program compiles, but does not run.

When I try to run the ...app, I get the message that the main class is not specified, etc.

When I try to run the ...jar, I do not get the message that the main class is not specified, but I do get the message that there is no Manifest section for bouncycastle, etc.

Here are the detailed messages I get in the Console when I try to run the program:

When I try to run the ...app, I get the following message:

When I try to run the ...jar, I do get the following message:

I do specify the main class in both, the Manifest file and the Info.plist file, in the correct way, "package.MainClass". Is there another place where I need to specify it?

Why do I need org/bouncycastle/asn1/DEREnumerated.class, and how would I have to specify it in Manifest?

Please help! Thanks!
