Cannot use Scala class in Java

Question

I believe Scala and Java can use classes from each other.

However, I found myself in a situation that my Java class cannot use a Scala class in the same package.

The scala class is defined as:

class CustomerService extends AbstractCustomerService {

The code trying to use this bit of code is:

public Deployer() {
        singletons.add(new CustomerService());
}

The error I got is:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3:compile (default-compile) on project orderservice: Compilation failure
[ERROR] \devel\raven\services\orderservice\service\src\main\scala\com\mxyy\orderservice\customer\Deployer.java:[12,31] cannot find symbol
[ERROR] symbol  : class CustomerService
[ERROR] location: class com.mxyy.orderservice.customer.Deployer

Can someone give me some hint about this?

Many thanks

Are your other Scala classes visible in Java? This sounds more like a Maven issue. — Submonoid

Thanks for your reply. What do you mean visibie? How to configure Maven to make it visible? — Kevin
