Working with java and scala in eclipse

Question

Am working on a project, it contains both java and scala classes.
My folder structure: is
src>main>java -> for java classes
src>main>scala -> for scala classes
When am importing scala classes in java, eclipse saying that no type found. I already installed scala IDE in eclipse. I don't know how to fix this problem. Can anyone help me with the configuration of eclipse to work with both java and scala?

Answer 1

I solved the problem by adding scala nature to project, As told by @jny:

Right click on Project -> Configure -> Add Scala Nature
