I think (and hope) that I finally have a working, stable environment for LiveCycle Data Services development. In my previous attempts, I have been plagued by Out of Memory errors (Eclipse 3.3 + Flex Builder 3 beta 2), strange “Unknown” problems (Eclipse 3.3 + Flex Builder 2), and missing plug-ins (Flex Builder 3 beta 2 stand alone).
My current approach is based on a great article titled Eclipse WTP + JBoss + Flex Builder + FDS Dev Environment Tutorial. In this case, the developer built his environment using slightly older versions of the tooling than I preferred, so I took a stab at building the environment with the following:
You might notice that Eclipse WTP and JBoss are not the latest and greatest as of this writing (in the case of Eclipse WTP, the latest is 2.0.1 and JBoss is 4.2.2). I made both of these choices for a reason. First, I had trouble running WTP 2 (built on Eclipse 3.3) with Flex Builder 3b2 earlier, so I wanted to avoid it initially. As for JBoss, the aforementioned tutorial points out that the Eclipse plug-in associated with the 4.2 version is a memory and CPU hog – a problem I had with my earlier trials also.
I am not going to go into full detail on set-up and configuration of the development environment here, because the development environment tutorial does a tremendous job there. Instead, I will point out a few, albeit minor, differences as well as a few key points:
-vmargs
-Xms256m
-Xmx512m
-XX:MaxPermSize=256m
-XX:PermSize=128m
set JAVA_OPTS=%JAVA_OPTS% -Xms256m -Xmx740m
Now that I have a working environment, I can start to integrate my previously built Java application (Spring + Hibernate + FDS) with my Flex frontend. I will document my efforts in future posts.
