In the meantime if you find it useful here's a basic swing application I use to do this for SQL that's embedded into the classes. I find myself using it over and over again so why not share it?

(a small note, its throw away code since I put it together in a week where I needed to rapidly format queries, I might clean it up at some point)

Java (as of 7) doesn't support HERE docs (also known as multiline strings) unfortunately.

If you're trying to accomplish templating, there are a few options:

These aren't exactly similar to HERE docs in Perl or PHP since the string that describes the template isn't directly in your code; it's usually in a separate file.

There was a proposal put forward by Stephen Colebourne as well as a proposal via Project Coin, neither of which made it into Java 7, which was a little disappointing. Languages like Groovy and Scala, which also run on the JVM do support multiline strings.
