Facing a casting error for splitter in camel

I am new to camel and I have written a code for splitter. I've written a context.xml which contains the routes and the beans for mapping the POJOs, and a FileSplitter.java file which contains the following code:

public class FileSplitter {
    public List<Object> split(Exchange exchange) throws IOException {
        List<Object> outputList;
        outputList = (List<Object>) exchange.getIn().getBody(File.class);
        return outputList;
    } 
}

I'm getting an error which goes like this. This is the console output:

    java.lang.ClassCastException: java.io.File cannot be cast to java.util.List
        at mainJava.FileSplitter.split(FileSplitter.java:15)
        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
        at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
        at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
        at java.lang.reflect.Method.invoke(Unknown Source)
        at java.lang.Thread.run(Unknown Source)

The error appears to be on this line:

outputList = (List<Object>) exchange.getIn().getBody(File.class);

The call getBody(File.class) will return a java.io.File instance, you cannot cast that to a List then, its always a java.io.File type.

Its like write in Java

File file = new File("foo.txt");
List list = (List) file;

Which you cannot do, and you get a type cast exception also.
