Java Development

[RichardPrice]

Hi,

I created a project which seems to be targetting the JRE 5.0.0 environment, how easy is it to change that to an earlier version of the JRE for earlier phones?  I am using the standard Eclipse with Blackberry Plugin setup.

Regards

Richard

It is based on the API's you have used in your application.

If you already installed the other JRE like 4.7 with your eclipse, you can change the version

Windows-Prefernce-BlackBerry JDE-Installed components

and change the version to 4.7. After this you just need to compile your project and you would know if you are getting any error or not.

Thanks

Personally I've gotten used to conditional compilation- when you call a BB API, note

how early it was introduced and at least use "#warning" if you know you need

stub code for earlier versions. I define something called RIM_OS_TGT and use g++

preprocessor which gives me all the familiar macro's from c++.

This works nice for maintenance unless there are severe architecture changes,

and in particular the browser fields were updated in 5.0.
