Currently, there is no JVM running on the iPhone. This means that the only way you have to develop apps for iPhone in Java is to have a compiler that will compile your java code down to Objective-C code.

There are several solutions that do exactly that:

Codename One - focuses on building applications using Java with visual tools and simulators. Open source with a SaaS backend that removes the need for a Mac.

XMLVM - a translator to convert Java bytecode to C/Objective-C. Open source, but requires writing iOS specific code at the moment.

There are also several proprietary solutions but I have no experience with them. E.g. Software AG has a tool called web objects.
