Not sure why I get this error, here's the code:

    private List<sss.DataTier.sss1.sss2> categoryList = new List<sss.DataTier.sss1.sss2>();
    LoadSSSList();

    private void LoadSSSList()
    {
        categoryList = sss.DataTier.sss1.sss2.GetCategoryList(sss.DataTier.sss1.sss2.Values.version, VID);
    }

    // this will give you a compiler error, because, as an interface, java.util.List cannot be    
    // instantiated.
    // instantiate something that implements List, like java.util.ArrayList
    //private List<sss.DataTier.sss1.sss2> categoryList = new List<sss.DataTier.sss1.sss2>();
    private List<sss.DataTier.sss1.sss2> categoryList = new java.util.ArrayList<sss.DataTier.sss1.sss2>();
    // this was causing the "must have return type" error. The compiler sees it as an invalid method  
    // declaration. It looks like what you want is to invoke the method declared below in an init block:
    // LoadSSSList();
   {
       LoadSSSList();
   }

    private void LoadSSSList()
    {
        categoryList = sss.DataTier.sss1.sss2.GetCategoryList(sss.DataTier.sss1.sss2.Values.version, VID);
    }

I was assuming you meant java.util.List. If it's actually a concrete class like in java.awt.List, then never mind the first part, and forgive my presumption. ;)

The part about the init block should fix the "must have return type" problem in any case.
