We have decided to use Flex3 to upgrade our UI. We have heard
good things about using Granite Data Services, but it requires jdk5
or higher, and the same for BlazeDS.
We are currently using Websphere 6.0 and are discussing our
environment options: replace Websphere with JBoss 4.2 (Sun jdk6),
upgrade to Websphere 6.1 (IBM jdk5), or keep the current Websphere
6.0 (IBM jdk4). The concerns are upgrade cost, and time to develop
and qa any changes to the environment.
We would like to get some feedback on pros and cons of using
Flex with these three environments. If we stay with jdk4, will we
spend nn% more time writing code that could have been done out of
the box with Granite? Are there improvements with memory, speed,
etc. using Flex with a later version of the jdk? Will development
time be shorter with a later version of the jdk? What are the
advantages and disadvantages of using Flex with WebSphere versus
