[Wrapper-user] Problem with thread
|
From: <San...@DM...> - 2003-02-13 17:34:44
|
I have a thread that executes an app (simply System.out.println()). Thi=
s
thread is called from the main method of the same class that invoque th=
e
wrapper.
If I execute this app without wrapper works OK, but if I execute the sa=
me
class from the wrapper it makes 4 iterations and JVM dies and then wrap=
per
creates another JVM.
I get the error below:
