In this show Paul Withers returns to enlighten us on what Data Contexts and Variable Resolvers are and how to use them in XPages.
In addition I want to send out some Happy Birthday wishes to:
Bruce Elgort and Mikkel Heisterberg and also a belated Happy Birthday Paul Withers himself!
In this show yet another NEW contributor comes on to share content with the community. Today, Stephan Wissel, IBMer and blogger at wissel.net comes on the show for a discussion on a programming design pattern called “Facade” and how you might want to use this in your XPages development.
In this show Jesse Gallagher, a great new contribitor, comes on to give us an over view of using Java Controller Classes to help seperate your business logic from your XPage. By moving your logic outside of the XPage you get much cleaner XML source for your XPage.
If you’re new to the thought of using Java inside XPages, I’d suggest don’t focus on the actual syntax that Jesse’s using here but the overall concepts. This is very similar to using Lotusscript custom classes to hold your business logic so you have cleaner agents and view buttons.
Hope you like it.
In this episode I welcome Serdar Besegmez, an IBM Champion and new contributor to the show. Serdar will come on to talk about DOTS. DOTS is way for you to create your own server tasks. Very fast and very powerful.
While this topic is a little more on the advanced scale, I think Serdar has done an excellent job of walking through the concepts of DOTS and then showing how to setup your development environment and finally how to run it on the server. He highlights additional resources such as a Show-&-Tell from Lotusphere2012 and even shows a key tip on outputting messages to the console.
I hope you like it.
In this show Russ Maher concludes his three part series on sharing Bean data inside your XPages applicaton. In today’s show he’ll talk about using Managed Properties.
Over the course of this series Russ has taught us a lot about Beans, Java, XPages/JSF concepts like variable resolvers and now Managed Properties for Beans.
I want to thank Russ very much for contributing all this great material to NotesIn9. I really appreciate it and I’m sure others have as well.
UPDATE: DEMO FILE for the show
In this show Russ Maher comes back on with the 2nd part his 3 part series on creating and working with Java managed Beans in XPages. While the purpose of this episode is to share data between multiple beans, and it’s not a pure “getting started with beans”, there’s a lot of good beginner information in here on how you can use beans and Russ also does a really good discussion on Java Maps. I like that he even talks about this code:
FacesContext.getCurrentInstance().getExternalContext().getSessionMap.get(key)
and describes what each piece really means. Russ will also introduce the concept of variable resolver which seems to be very popular with the advanced XPages developers.
This content should not be missed for an XPages Developer.
This show is the first part in a 3 part series from another new contributor to NotesIn9. I’m very excited to bring onto the show Russ Maher who is an excellent XPages developer and speaker. Russ is going to show us how you can use Managed beans to solve a business problem in XPages.
Since this show is once again talking about Java I mention some resources on getting started with the Java Language, especially in learning the syntax. I’ve used the Head First Java book and liked it very much but recently I found a great new website designed to teach the Java Language.
http://howtoprogramwithjava.com
This site is run by Trevor Page. I think it absolutely rocks. It’s has great getting started with Java information that’s very well written in an easy to follow manner. Trvor also does a Podcast and has produced a really good ebook on the subject. I highly recommend checking his site out for anyone who’s starting to learn Java.
He also has a site specifically setup for his Java ebook here: http://javapdf.org You can download a sample and check it out. I bought it as soon as it came out and it’s really well done.
There’s lots more Java XPages material coming to NotesIn9 as well as non Java shows. Remember, as Paul Calhoun likes to say, “Java is just a tool in your XPages toolbox”. I think it’s a really good tool to have.
UPDATE: DEMO FILE for the show
In this show I attempt to tackle the “forbidden topic”. Yep. Java. Me talk about Java. It’s unexpected. I know. This show is an expanded version of parts of a presentation that I did at MWLug.
I first talk about some of the tools available to the XPages developer and when you might want or not want to use some.
Then I get into the meat of the show – Java Beans. I try and explain exactly what they are and show what they look like. I talk about managed and “unmanaged” beans and go through what they look like and a little bit on how they can be used.
This is a “getting to know them” type show. Not an indepth getting started on building them. I didn’t intend to do this show quite yet but I’m getting some great contributions as part of the Drive to 99 Event that are starting to talk about Java beans so I wanted to get this little intro out.
There’s lots more Java Beans stuff coming. If you can’t wait Jeremy Hodge did 3 shows for NotesIn9 that are highly recommended. I’ll probably be doing my attempt and an indepth intro to Java in the near future as well.
If you have any questions please ask.
P.S. This show is about 36 minutes and I got it in 1 take! BOO YAY!! 🙂
In this show Jeremy Hodge comes back to continue his ongoing series on helping XPages Developers get started with Java.
