Not sure what i'm doing wrong, but, I cannot get the javac task that gets invoked from rapc to use -source 1.5

The line always shows -source 1.3 -target 1.1

I DO NOT have 1.3 or 1.4 installed, I have ONLY had 1.5 installed on my system.

How do I override the -source 1.3 argument that's getting passed to javac?

Sincerely,

Why is it a problem? You don't need 1.3 or 1.4 installed. It's invoking the installed javac compiler (1.5) and telling it the version of source code it's getting is 1.3. Why do you need to change it?

I may be confused here. Can we only program for the blackberry using the 1.3x JDK?

I had assumed that if I develop in 1.4, or 1.5, I could change the -source argument to specify that the source code it written in 1.5, and that the -target argument would "downgrade" my code to a 1.1 JVM target? I had thought I could use 1.4 and 1.5 features and it would get downgraded, but I guess that's a pretty tall order.

However, I've created a very SIMPLE test using the DecimalFormat class that indeed does exist in the 1.3 JDK.
I'm working in the Eclipse environment using the eTaras RAPC c ANT task. So, I'm developing in Eclipse, but doing the deployment/simulation via an ANT script which compiles for me. I'm using the V1.8 eTaras jar.

Here's the error I get :

Hi, mdwheaton!

You confuse java language versions and java API versions.

java compiler directive "-source" defines version of language, not API. You can define "-source 1.5" and use 1.5 language features (as soon as they don't depend on new APIs). But you can't use JDK 1.5 API (and JDK 1.3 too, btw).
You can only use API, available on BlackBerry device, and it doesn't depend on javac.

To find available APIs, see javadocs, bundled with JDE, or <SIMULATOR_PATH>\lib\net_rim_api.jar.
This is CLDC1.1 + MIDP2 + bunch of BlackBerry-specific packages: net.rim.*
