Does anyone know how to generate WSDL from a Web Service in Ruby using Soap4R. I have a fairly simple Web Service (SOAP::RPC::StandaloneServer) and would like to consume from .NET .

Turn off inlining of functions. The easiest way to do this is to just compile in Debug mode. |

**Edit:** after seeing your clarification, I find my answer is in error. Perhaps if you moved the body of the function into another section of the .h file, using the "inline" keyword? |

You should learn whatever you *want* to learn. If you don't you'll probably find it harder going than you need to.

In my oppinion, a novice should conentrate on the basics and internals of the language of choice. Graphical or web interfaces should wait until you know what you're doing in the backend.

There are currently several competing proposals, [BGGA][1], [CICE][2], among others. Unfortunately, a heated debate remains over the best approach. As a result it is unlikely at this point that closures will make it into Java 7, due to the conservative nature of the acceptance process.

You need to configure the server daemon to only bind to localhost using the Listen directive like this:

I just like them because they give you a quick way to define a custom type (as I use them anyway).

Exceptions are intended for events that are abnormal behaviors, errors, failures, and such. Functional behavior, user error, etc., should be handled by program logic instead.

It's always pretty dodgy, especially if you're allocating resources inside a constructor; depending on your language the destructor won't get called, so you need to manually cleanup. It depends on how when an object's lifetime begins in your language.
