Hello.
I have a task to write a web service with use of Hessian and Spring.

For a while I have been struggling to integrate scala with java methods that might return null. I came up with the following utility which helps a lot:
// produce an Option, nulls become None
object Maybe {
def apply[T](t:T) = if (t==null) None else Some(t)
}
Maybe(javaClass.getResultCouldBeNull()).map( result => doSomeWork(result) )
I have a few questions about this solution:
Is there a better or more standard pattern to use?
Am I duplicating something that already exists?
Does this functionality have hidden gotchas?

I am working on parsing plain text and converting it to key-value pairs.
For example, plain text:
some_uninteresting_thing
key1 valueA, valueB, valueC
key2 valueD
key3 valueE valueF
key4 valueG(valueH, valueI)
key5 some_uninteresting_thing valueJ some_uninteresting_thing
key6 some_uninteresting_thing
(key6 shouldn't be mapped because has no appropriate values) As you can see plain text is lenient. What java library can handle this? If no such library exist, any suggestions on algorithm to do this.
I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques.
I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is.
I would like to know the same thing for commenting as well.
I want to make an Application that uses RxTx version 2.2pre2 to work with Serial Ports. What are the Licence restrictions, since it is an "LGPL v 2.1 + Linking Over Controlled Interface" licenced library if I don't use the Sun's javax.comm.* interface, but the RxTx's own gnu.io.* when importing into Java Files?
Is there an easy way to convert between color models in Java (RGB, HSV and Lab).
Assuming RGB color model:
How do I calculate black body spectrum color palette? I want to use it for a heatmap chart.
How about single-wavelength spectrum?

In a jboss service I need to mock some inner class (not EJB) with JMockit. Just for tests I've created inner class ToBeMocked and another one Mock. While deploying to jboss I get error NoClassDefFoundError in line:
Mockit.setUpMock(ToBeMocked.class, new Mock());

Any ideas?

How can I read, in my servlet, the server side, the login and the password user is sending, in java code?
