You don't need to use the "embedded SE" version of java on the pi. It is not really an embedded platform. It is a regular PC, albeit a minimal one.
WRT OpenJDK, it is actually a Sun/Oracle product, who of course own the java spec and the mainstream JRE/JDK. OpenJDK started as a fork of Sun java 7, I think primarily so it could have a GPL license. I.e., OpenJDK is essentially the open source version of Oracle java. The difference is more in the licensing than the code base.
I haven't seen any tests, but I would imagine the fastest java for the pi is the Oracle 8 preview (which is actually a binary compiled from openJDK with hardware float support). You may also want to look at this question this question.
But the compiler is missing
Make sure you download the JDK (devel kit) not just the JRE (runtime environment). This may also be a problem with javac not being in your $PATH, see my answer to that other question.
