将 scala 功能添加到现有 EJB eclipse 项目中
我在 Eclipse Helios 中建立了一个现有的 EJB 项目，并且想慢慢地将 Scala 引入到该项目中。 Scala IDE 已成功安装，我可以创建独立的 scala 项目。然而，当尝试将我现有的项目与 Scala 添加一起使用时，问题就出现了。我已经手动编辑了 .project、.classpath 以及 Eclipse 项目主目录的 .settings 下的相关文件。
但是，我仍然遇到 Java 编译器尝试编译 .scala 类的问题，这会导致错误并最终无法构建项目。
有没有人遇到过类似的情况或者有什么解决方法吗？
提前致谢。
I have an existing EJB project set up in Eclipse Helios, and would like to slowly introduce Scala into the project. The Scala IDE has been installed successfully, and I'm able to create standalone scala project. The issue however comes when trying to use my existing project with scala additions. I've went as far as manually editing the .project, .classpath, and related files under .settings of the project's home directory for eclipse.
However I still have the issue where the Java compiler tries to compiles .scala classes, which results in errors and ultimately not being able to build the project.
Has anyone faced a similar scenario or are there any workarounds?
Thanks in advance.

您应该能够右键单击该项目，转到“Scala”并单击“添加 scala nature”。那么
.scala文件应该被这样识别。您可能还需要将 scala 库添加到您的依赖项中。根据这是一个“简单”Eclipse 项目还是您正在使用 Maven，可能还需要其他步骤。You should be able to right-click the project, go to "Scala" and click on "add scala nature". Then
.scalafiles should be recognized as such. You might also have to add the scala library to your dependencies. Depending on whether this is a "simple" Eclipse project or you're using Maven there might be other steps required.右键单击项目，然后选择配置/添加 Scala Nature。
Right click on project, and choose Configure/Add Scala Nature.
