I know that you can dynamically detect supported classes, but I would be surprised if picking a random class that should only be in a particular profile/configuration were the proper way of doing this. ...
I want to be able to support multiple versions of Java ME without having to have multiple builds. I already know how to detect the profile/configuration/supported JSRs. My problem is that knowing whether the JSR is supported at run time doesn't allow me to use all the features as Java-ME does not provide support for reflection. For if I...
