Only if Bobs code it, properly coded its actually maintainable. I just would not be able to do my work without reflection.

Agree with that.

If the schema designer has not thought about how schema entities map to type relationships in the code bindings, you can end up with lots of duplicated code that you can't "common up", because of a lack of common base classes in the bindings. You can get around that using reflection. I removed 75% of a code base recently by doing this. You present a type safe layer to callers, all the reflection is hidden from client code.

I keep coming across this problem. These TIBCO experts write these schema and often they are rubbish.

Can I ask how you end up with a system that relies on generating code at runtime driven by XML, with no schema support?

By hiring people who think that is a good idea. We didn't, so that isn't how we solved that particular problem.

What in the business drives this requirement?

Our customers want to be able to integrate our products with their other systems without the cost and complexity of coding from scratch. We will generally have schemas, but requiring our customers to preprocess them, compile, deploy the resulting code & glue it all together isn't an option.

Worked on a few generic data applications, they usually start off quite innocent and well meaning but at some point people start concrete coding in the generic types ( usually quick hacks "For the business" ) then all hell breaks loose.

Sounds like a debugging/maintenance nighmare...

A BA got me into a conversation last year asking if it was possible for a current production application to start creating tables, rows and then populate the tables with data as and when required.

It was battulip crazy ideas like that caused skynet to become aware.

Anything that relies on reflection to emit types at runtime is going to be a maintenance nightmare in any case, because you cannot see what you are coding. It will just be a code with lots of GetType(), GetProperties(), GetBindingFlags() and the likes.

I can now see why you lot are contractors. You have no choice. Too long in the tooth to get permie growth roles. Not big picture enough to get senior permie roles.

It's a terrible price we pay, pocketing a six figure income for 30 years and then putting our feet up.

Well this is pretty much the first thing the guy who gets the gig is going to be working on, so it seems to prudent to ask how he'd go about it.

Core Skills:

Java. Web Services. XML. Modern development practices (CI, TDD etc). Good design & problem solving skills.

Technical interview question #1:

You have a tree data structure that you need process, doing something different with each leaf in turn, and collating the results into another parallel tree. How would you go about that?

There is a question #2 for people who do well on #1.

You are asking the wrong question. Try "can you give an example where you have bribed the interviewer to get a role?".

The problem that you are crap at finding suitable interview questions? I think dim covered that a fair few pages ago and gave you a better structure.

At this stage I'm not being language specific, I'm just trying to see if you have actually grasped the problem.

Just use C++ like a real programmer.
I could even port it for you?

I don't think any of us are talking about Java except yourself
