If I realize a software that uses SWT and Java library, then I compile it with gcj into an exe and distribute it without the sources... is this legal?

From what I understood I could do the exe of the program and then put in the cd of the program both gcj (GPL) and swt's (EPL) sources but not my .java sources. Is it right?

I'm blocked... Can I or not?
Inside the about.html in the swt distribution it's written that there are pieces with the mpl license, and the mpl license implies that I have to distribute the source code too.
What's the sense of releasing a library under epl and then put inside of it all this things with other licenses?

I didn't know that doing a simple thing like a simple software takes to all these troubles.

Nothing is clear, all is confused Sad

The EPL and MPL licenses in SWT/Eclipse are not viral, they apply solely to
the SWT/Eclipse components being used. They only stipulate that you must
provide some source if you make any modifications to the SWT/Eclipse source,
in which case the changes must be made available by some means (eg.- a file
accompanying your app, a link to a site, etc.). However you can license
your own app any way you want, and as a consumer or Eclipse/SWT are not
required to provide any EPL or MPL license texts.

The only remaining piece is gcj, you'll need to look into its terms
separately (eg.- does it say that the end product of a compile is
automatically assigned license XYZ, etc.).

I found here that for gcj there should not be any problem:
