Does anyone know where or how to obtain a Java example to create iPhone apps? What I am looking for is just using Java (no objective-C or just the bare essential objective-C) and no interface builder, source only.
There is no Java SDK for iPhone. XMLVM is something experimental from academy you might want to try. But it's not complete of intended for production use.
There is no Java ME API support in iPhone either. Or any other kind of Virtual Machine for that matter.
If you are looking for something similar to Java (but is not Java) you might give MonoTouch a try. It's Cocoa API for C#. From Miguel De Icaza and the great Mono devteam!
If you can live with your application running only on jail broken devices, you might try Cydia repository.
Captain Steve don't want You to use Java, as it has an ugly font. (or something like that)
Your options are: target android*, or follow Captain Steve.
*) actually, android isn't really Java either, just really really nearly java, but with a crappy jvm and a lawsuit from oracle going on...
If you want a very messy and unsupported build sequence, you might be able to write some sort of Objective C wrapper library that would support using the output of one of the Java-to-C (Java2C? Toba?) translators. Note that this methodology may not comply with the iPhone SDK agreement.
But there is no supported tool or examples that I am aware of.
