Java rte and/or api install for j++

Question

hi...i need to use some classes from packages that are not showing up with j++
i was wondering if i was to download the j2rte wether that would solve the problem
or if its somethine that j++ needs to be adjusted to see the classes(i.e. java.util.dnd) which is not installed on the jvm right now.
does this sound ok as a question or should i rephrase????

Answer 1

I think when your application invokes the compiler
your application is the launcher
and any -J[i]-option should instead be passed to java when invoking your application.Makes a lot of sense.
Here's my understanding of it.
java, javac javah etc (or window's javac.exe etc) are little wrapper native programs that launch the JVM using the JNI functions, which runs a main() method in the specified class.
The -J options are interpreted by the wrapper and used to configure this JVM via the JNI functions. They are discarded and not passed through as args to main().
So javac (the java program) never interprets those -J options, because they have already been actioned by javac.exe the wrapper, and once javac actually starts to run, it is too late 'cause the JVM is already running.
Thats why the compiler API says it doesn't understand that option.
If you are using the compiler API, you are not starting a new JVM, just running the compiler code inside the JVM that is running your program. In fact that is the whole point of the compiler API.
So if the compiler being called from your program needs more memory, then your program needs more memory, just like if any other api you called needed more memory.
