I just stumbled upon this while checking the #scala twitter feed.</p> <hr> <p>You can have a look at <a href="http://github.com/alandipert/step" rel="noreferrer">http://github.com/alandipert/step</a>. It looks like an active project with just enough to let you write Scala code mixed with xhtml code. Whether you can <em>script like PHP</em>, I don't know. One of the difference is that with JSP/PHP, you include a program inside an HTML page where as with <code>step</code> you include some <code>xml</code> into a Scala file. </p> <p>There is going to be a bit of a learning curve with Scala and <a href="http://code.google.com/p/simple-build-tool/" rel="noreferrer"><code>sbt</code></a> but I think it's worth it to take advantage of Scala.</p> <p>The other thing you can do is to write a custom JSP tag that lets you run some Scala code through the interpreter. I did a proof of concept and this seems to work:</p> <pre><code>/** * Proof of concept, you can run Scala code in a JSP tag. * Works with jetty and sbt. */ class ScalaScriptTag extends BodyTagSupport { override def doAfterBody():Int = { try { val settings = new Settings(str => println(str)) // interpreter classloader does not seem to pick up classes from the parent settings.classpath.value = "lib_managed/compile/jsp-api-2.1-6.1.14.jar;" + "lib_managed/compile/servlet-api-2.5-6.1.14.jar" var i = new Interpreter(settings) { override def parentClassLoader():ClassLoader = { return Thread.currentThread().getContextClassLoader(); } } i.bind("pageContext", "javax.servlet.jsp.PageContext", pageContext) val source = Source.fromString(getBodyContent.getString) for (line <- source.getLines) { i.interpret(line) } } catch { case ioe: IOException => throw new JspException(ioe.getMessage()) } Tag.SKIP_BODY } } </code></pre>
