Use Scala as if it was Java

Question

I've been reading up on Scala a lot recently and I really want to get into it. I do my Java web development from within Eclipse with Tomcat as my preferred server and I'd like to keep it that way. I've tried the Scala Eclipse plugin but it's safe to say, it isn't there yet. I had to uninstall it because it simply ins't working. On top of that, it doesn't seem to provide anything for doing web projects (I could be wrong there).

Since Scala is a compiled language just like Java is, I was wondering if it's possible to simply swap out Java with Scala, as in, where I'd normally would create Java classes I would now be able to create Scala classes instead? Maybe even mix Java and Scala?

Is there anyone out there who's been able to set up a decent Scala workflow in Eclipse for web development without the dreaded "official" Scala Eclipse Plugin?

PS: I've tried the Play framework (I think it recently added Scala support) but it simply isn't for me. I like my classes compiled and to use JSP's for my views.

Answer 1

You don't say anything about what version of the Scala IDE for Eclipse you were using, or what you tried to do to resolve your issues. I suggest that before changing your workflow you head over to http://groups.google.com/group/scala-ide-user and see if we can help you out.

Yes, absolutely. That's one of Scala's big advantages over some other JVM languages.

Make sure you have familiarity with the Java and Scala collections libraries (and that you keep them straight -- if you're planning using advanced Scala features on Java collections, definitely use a Scala 2.8 release candidate). Also make sure you're faimilar with the @BeanProperty annotation -- it can simplify your Scala coding somewhat.
