Re: [Wrapper-user] Unable use wrapper linux in RHEL 4

[Leif M. <le...@ta...>]

Cyrene,
    Your main method is correct, but the testfile class is not public.
Change
class testfile {
to
public class testfile{

    I was able to reproduce this with a class in the root package as you 
are doing, but
it appears to work fine as a public class even if the public token is 
omitted when the
class is located in a package...  That seems wrong.
    If I attempt to run the class from java directly then it works in 
both cases... Anyone
know about any documentation where this is described.

Cheers,
Leif
