Where can I find a Java decompiler?

Hi,

how to get the source code of a java exe file (an simple application)?

(I know its not obfuscated)

EDIT: Its an Exe File, not more not less, no *.jar

Answer 1

Well, first step would be to try to find program which turned the .jar into exe. After that you would need to study how that program is doing its thing and find a way to reverse it. After that, if you manage to get raw data, you'd use java decompilers.

You could take a look at this question for example and start from there: How can I extract java exe to jar
