Hello,
We're having a problem remotely debugging a Java program running on an
iSeries machine from Eclipse (running on a Windows XP machine).
I'd greatly appreciate any help on this issue. By the way remotely
debugging worked fine till about a month ago, so we're pretty confident
our parameters etc. are all correct.
In summary, when we attempt to remotely debug our Java application, we
always receive a "com.sun.jdi.VMDisconnectedException: Got IOException
from Virtual Machine", and the debug session terminated.
By running 'netstat' on the iSeries machine we can still see the debug
listener is up and passively waiting. From the number of bytes in/out we
can see that a connection did occur and about 25 bytes were passed to the
iSeries, and 14 bytes out.
The error log from Eclipse is as follows (cleared before the error):
