java.util.Collection<java.lang.String> getClassNames()
```
    Returns a readonly collection of the logic names of the class (never null). Note: it is the name to resolve class, not the real class name. In other words, it is the logical name maintained by this function mapper.
  - resolveClass

java.lang.Class<?> resolveClass(java.lang.String name)
                         throws XelException
```
    Resolves a class with the specified logic name, or null if not found.
    Note: not all EL evaluator support resolveClass(java.lang.String). JSP 2.0/2.1 EL-based expression factories don't support this method. You can check ExpressionFactory.isSupported(int) for this support.
    
    Returns:
    
    the class of the specified logic name.
    
    Throws:
    
    XelException
