Re: Compile java files in packages

[Vaijayanthi Mala Suresh <vaijayanthimalas at gmail dot com>]

Hi ivanceras,

Can you please let me know how to do it for java files within packages.

For eg. I have mytest.java under com.test.

if i give gcj -c ./com/test/mytest.java it gives me error.

Thanks
Mala
