Estou tentando fazer o scalate funcionar no Tomcat, mas ele trava ao tentar compilar os modelos scaml.Não há problema com Jetty.Eu sou novo nisso e no Tomcat em geral.Parece também que o protótipo scalatra-sbt no github trava, o que me faz pensar que o Tomcat não está configurado corretamente.

Alguma dica sobre como fazer o compilador escalar funcionar no Tomcat?
Solução
Você tem scala-compiler.jar implantado com os outros frascos?
