Personally I’d recommend as many relevant lower level computing and technology courses as possible before tackling T320 Ebusiness Technologies. I’ve just heard about a new distance learning course in Linux from the OU that sounds like a very good option, as it includes practice in setting up a web server, user management and security.

It was in Block 4 that it really became a disadvantage to be taking the course in its first year, though I still think T320 (especially the e-business aspect) was one of the most interesting OU courses I’ve done.

One of the tricky things about blogging about an OU course is that you’re not allowed to publish your actual assignments (or their course materials, obviously!) But this is the list of references I used in writing the ECA report. The ECA for my year was about using ebusiness technologies as part of a healthcare information management system for American-owned private birth centres in three locations in the UK.

I finished the TMA (hooray) but not without some Herculean effort and wasted time spent wrestling with technical problems with Eclipse. So here are the problems and answers I found – may it save someone else some much needed time as the deadline approaches!

What with XML, SOAP and WSDL documents all using XML and XML Schema, they seem so alike. Starting to learn them by reading about them is like trying to memorise the phone book: I really need to get on with the practical activities to make some more sense of this. Thankfully (I think) there are many of these, but there isn’t much time for the TMA! I hope the reason WSDL is confusing is because it’s the first of the set that I’m reading about. The WSDL unit summary reminds me ‘WSDL is the language for describing web services so that they can be accessed and used by clients, either manually or automatically’… Hold that thought!

I followed the instructions from the first activity in Block 3, clicked Finish to generate my web service in Eclipse, waited, waited, and got… a 404 Not Found page – aaargh! Had to go out almost immediately, but checked again when I got back and noticed port numbers being mentioned. So I tried switching off the Windows firewall, and hooray! My first web service!! It asked me my name and said Hello to me. (Ok so that part was not a surprise, but it was so great to see it working!)
On checking it out, I noticed all kinds of other files had been generated: WSDL, metadata, Java classes and libraries, and more – I guess that’s the rest of Block 3 then…

I got 94% for TMA 2 – one of my best grades ever! I thought it was really hard, especially developing the XML Schema. But I guess I must have kept on at it enough and made some lucky deductions about what things meant. Also, when I made references to the security considerations covered at the beginning of Block 2, those seemed to be well received.
I’m still not entirely clear on how DOM, SAX and XSLT relate to each other, but hopefully that will become clearer later as I do more of the practical work.
I think in this section of the course I have really benefitted from having just completed the certificate in Web Applications Development beforehand – it covers some similar ground, though from more of a technical development perspective and with different programming languages and technologies.

Got my TMA in – I thought parts of this were quite hard and / or confusing, but these are the links that I found helpful:

Here are some useful links for Block 2, mostly about XML, XML Schema, XSLT etc, including a free book to download.
