I still meet Domino developers who want to use XPages in the way IBM told them how to use it. Completely wrong I would say. Now that you have to chance to learn Java skills – EMBRACE IT!
Okay the other way around is sometimes a pain in the ass and complete examples are scarce but it gives you a better way to control your application and it’s behavior. After a while you get better understanding of the underlying technique and there is nothing wrong with that.
At the end it is mostly about creating, reading, updating and deleting stuff.
So for those developers I have setup a simple presentation to get a better understanding of JSF, Java and XPages:
Hi there, currently I am following another Angular course since it seems to have become the leading development framework at work. So back to learning all the rules within Angular.
At the moment I am modernizing a Domino application with the help of XPages which:
- Implements Model-View-Controller architecture, mostly inspired by the guys at Pipelia since IBM never told us to do so.
- Is written in Java to support the MVC architecture and to have close integration with XPages runtime.
- Is using Expression Language wherever possible to avoid usage of SSJS.
- Uses the lifecycle of JSF in XPages at the max.
- To cover support for different devices I am using Bootstrap as front-end framework. So I miss some native behavior which I do not tend to cover-up.
So far so good and I think I have come quiet long in my project so I still dare to call it rapid application development.
I know I haven’t touched many areas discussed in the XPages community such as:
- Websockets (I do not see a use-case yet).
- Writing Java servlets (please pass me a demo NSF).
- Watson services (cloud is still a sensitive topic).
- set up micro-services with smartNSF and consume them in my Java code with an mapper library (requires changes in the environment).
- Integration with IBM Connections.
- Redefining my data with the help of a Graph DB.
Either I see little usage, it is not possible or there is no-one to guide me (the information is certainly not provided by the vendor).
So now back to Angular. Learning all these rules, technologies and new tools setup I was wondering what new technical options this framework will bring me at work. Reflecting on the type of customer-orders I receive I am wondering:
Is XPages not sufficient for most of your line of business apps?
Perhaps you have a though about this?
Happy development & enjoy your summer 🙂
Yesterday I participated in an Advanced XPages Workshop by Emvege which was interesting. In the course material was a presentation on the JSF Expression Language which is also available online: link.
