Cleanest way to build an SQL string in Java
...consider using query parameters in prepared statements:
PreparedStatement stm = c.prepareStatement("UPDATE user_table SET name=? WHERE id=?");
stm.setString(1, "the name");
stm.setInt(2, 345);
stm.executeUpdate();
The other thing that can be done is to keep all queries in properties file. For exa...
Java to Clojure rewrite
...bly going to be your default choice - they allow you to implement "normal" STM transactional behaviour by wrapping any code in a (dosync ...) block.
Select the right overall web framework - Clojure has quite a few already but I'd strongly recommend Ring - see this excellent video "One Ring To Bind ...

Lock-free multi-threading is for real threading experts
...as @Eric mentioned, Joe Duffy is a definitive read on the subject.
A good STM can get as close to fine-grained locking as it gets and will probably provide a performance that is close to or on par with a hand-made implementation.
One of them is STM.NET from the DevLabs projects of MS.

Build.scala, % and %% symbols meaning
...s without the %%:
val appDependencies = Seq(

Assuming the scalaVersion for your build is 2.9.1, the following is identical:
val appDependencies = Seq(
"org.scala-tools" %% "scala-stm" % "0.3"
)
As you can see above, if you use %%, you do...
