There's a constant discussion about Scala being a complex language. In this post I'll try to show the simple parts of Scala that make coding easier.

My favorite article about why Scala is not complex is by Martin Odersky, the father of Scala: http://lamp.epfl.ch/~odersky/blogs/isscalacomplex.html. But there's one problem with it, it appeals to those already in favor of Scala.

I think Scala *is* complex. Some due to the functional concepts that are foreign to the Java world, some due to the requirement to work inside the JVM (and CLR). In fact, I was against Scala since 2006, because then I tried to learn it and found the syntax awkward. I recently had to start using it because a client required me to and haven't looked back since.

Ok, so now to the actual post, why should you use Scala: because some parts of it make programming easier even for novices:

Hi,

A client had this issue. Instead of presenting the whole case, here are two links that explain the scenario and provide possible solutions to this issue if you ever encounter it:

Tikal's recent experience with open source business intelligence, data analysis and report generation tools such as Pentaho CE and many others had proven that the tools are efficient, simple, flexible, scalable, reliable and as free as Linux or Apache. 

Here are 2 useful links which explain this feature and have some examples:
http://wiki.eclipse.org/Jetty/Feature/Continuations
http://docs.codehaus.org/display/JETTY/Continuations : see How it works section.

I use the eclipse version org.eclipse.jetty --> jetty-continuation in one of my client's projects and find it a very useful, powerful and reliable.

You can manage: timeouts, suspending a request, completing implementations, resuming a request, initial phase, adding continuation listeners or just handling the requests in a simple servlet without listeners and only by checking isComplete,isInitial etc...
