No, you need a java virtual machine.
rt.jaris also interpreted by the virtual machine and is just the java class library.If you’re looking to turn the code native you might consider gcj which can convert java code to machine code and wrap it up in an exe as per gcc. However, I’m not sure what version of java gcj supports – I’ve read somewhere it isn’t very recent.
It looks like Launch4j can include a bundled JRE, so you might consider this.
