Mind adding an empty line before private? I know, pedantic :)

+    std::string toString(const v8::Handle<v8::Value> exception,

We are starting all function/method names with an uppercase letter so far,
following the Mozilla conventions.

Since this method does not access any members, I'd just use a free function in
the unnamed namespace in JsEngine.cpp instead. But it's up to you of course.

I prefer having this a method for reasons of better grouping, no reason to
pollute global namespace. I made it static however, it doesn't need a class
instance indeed.

+        const v8::Handle<v8::Message> message);
   };
 
   class JsEngine
   {
   public:
     JsEngine(const FileReader* const fileReader,
              ErrorCallback* const errorCallback);
     void Evaluate(const char* source, const char* filename = NULL);
     void Evaluate(const std::string& source)
     {
       Evaluate(source.c_str());
     }
     void Evaluate(const std::string& source, const std::string& filename)
     {
       Evaluate(filename.c_str(), source.c_str());
     }
     void Load(const std::string& scriptPath);
     std::string Call(const std::string& functionName);
     void Gc();
 
   private:
     const FileReader* const fileReader;
     v8::Persistent<v8::Context> context;
     inline v8::Handle<v8::Script> CompileScript(const char* source, const char* filename);
   };
