I tried to create a test application to reproduce the issue. I used JNI and
called my test bench which intern opened the dll & called
pcap_findalldevs_ex. In the test application pcap_findalldevs_ex didn’t hang
and everything worked fine. Later I spoke to my colleagues and figured out
that we use XPCOM to interface between Java API & C++ debugger. I
haven’t created a test application using XPCOM yet & would take some
time for me. <o:p></o:p></SPAN></FONT></P>

pcap_findalldevs_ex hangs inside java process<BR>><BR>>

Hi,<BR>><BR>>
I am
using the Winpcap lib in<BR>> eclipse (Java) environment and
“pcap_findalldevs_ex” work<BR>> fine return all the devices but when I
use eclipse directly<BR>> Java in command line-mode i.e. in command
prompt then<BR>> “pcap_findalldevs_ex” hangs, never return whether it
failed<BR>> or passed. I suspected the “Remote Capture Service” is
not<BR>> getting started, so I tried enabling the service manually
&<BR>> tried but still the “pcap_findalldevs_ex” hangs. Any clues
on<BR>> what’s going wrong here?<BR>><BR>>
