ParaNamer support in Waffle as an alternative to annotations

The latest release of Waffle (0.7) can now fully support ParaNamer as an alternative to annotations. ParaNamer provides "method parameter name access for versions of Java PRIOR TO Java 7.0". ParaNamer combined with Waffle will allow you to utilize your ActionMethod parameter names directly. In the example below Waffle will use "itemId" and "quantity" to resolve the arguments for the void removeFromCart(Long, int) action method.

public class ShoppingCartAction implements Serializable {  
    ...  

    // No annotation is necessary when utilizing ParaNamer  
    public void removeFromCart(Long itemId, int quantity) {  
        cart.remove(itemId, quantity);  
    }  
}

For complete details on this please see the documentation on Waffle ActionMethods.

Describing Waffle with one picture

The Waffle team has been busy over the last few months adding features and simplifying the overall design. Much of the documentation has been updated to reflect these changes. Many times however, it is easier to describe something with a simple drawing or a picture. So have a look at the following to get a clear idea of what Waffle provides:

Ruby on Cygwin error (*** unable to remap)

I had an annoying issue occuring when running Ruby under Cygwin. The error was reproducable every time that I attempted to run the ri command.

C:\cygwin\lib\ruby\1.8\i386-cygwin\readline.so to same address as parent(0x370000) != 0x2760000
C:\cygwin\bin\ruby.exe (3132): *** unable to remap C:\cygwin\lib\ruby\1.8\i386-cygwin\readline.so to same address as parent(0x370000) != 0x2760000

I was finally able to resolve the issue with the following steps:

1. exit from cygwin


2. enter the dos command prompt


3. cd to you cygwin bin directory (c:\cygwin\bin)


4. run ash rebaseall


5. restart cygwin ... problem solved
