Designing a public website with Xpages
Sat, Mar 3rd 2012 7:23a Vince Schuurman My wife started her own business recently and she asked me to develop her site. I decided to design it in Xpages because one can never practice too much ;) Normally this would be a no-brainer because like most people I reuse a lot of my code/design elements. This time however, because this was to be a public site (I normally develop for intranet and business to business) and the total different way Xpages (can) work, I decided to design a new website from scratch.

Recompile code when opening in designer (xPages)
Wed, Dec 7th 2011 6:02a Vince Schuurman I found out the hard way that opening a database in Designer 8.5.3 can recompile all the code in the Java source folder, even if the 'Build Automatically' is unchecked.
So if you open a database that is in use, it might crash the database with:

xAgents, xAgents everywhere....
Tue, Nov 15th 2011 9:03a Vince Schuurman I am currently working on several concurring development projects and I noticed that the focus is shifting from creating 'pure' xPage documents to xAgents (an xPage set to behave like an agent) to replace 'webagents' used for WebQueryOpen, WebQuerySave or Ajax events.
The 'old' functionality was written in either LotusScript agents, Java agents or Servlets.
The reason for converting the 'webagents' to 'xAgents' is that they offer more performance than LS agents, are more stable than [read] Keywords: agent

Sat, Oct 8th 2011 4:43p Vince Schuurman I was getting pretty tired of editing the Java code in the Web-INF folder, the Java source in Designer is a big step forward. Still think it would be best if we could just use the Java scriptlibraries used by Java agents though, that would save a lot of double coding.

Converting 'Legacy' Java libraries to xPages code
Sun, Feb 6th 2011 2:02p Vince Schuurman I developed a demo xPage application this weekend using 'legacy' java code that is currently in Java Scriptlibraries for Domino agents.
It was not a trivial task because there is a slight difference between the way the classes are initiated.
Yes sure there shouldn't be a difference, but the older versions of Domino designer were much more forgiven about the way classes were called.
For me the best approach was to first port the code to Java 1.5 by recompiling the script libraries in Domino [read] Keywords: domino
