Hello,

when i try to start my Tomcat 5.5.17 (or higher), get the following error:
…
4A configuration error occured during startup. Please verify the prefenrce
field with the prompt: ERROR: transport error 202: vconnection failed:
Connection refused[“transport.c”,L41]
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
[“debugInit.c”,L500]
JDWP exit error JVMTI_ERROR_INTERNAL(113): No transports initialized
…

My Configuration ist winxp sp1, eclipse 3.1.2, jdk1.5.0_06 or i also tried jdk1.5.0_12.
I could launch tomcat in nondebug-mode from within myecplise. I could also launch
it from the catalina.bat in non- and debug-mode. I have an entry in hosts:
“127.0.0.1 localhost”.

What i found is, that i could reach the tomcat from the browser with 192.168.0.5 (that’s
my local ip) but not with 127.0.0.1 neither with localhost.

When i do “route PRINT” i get an entry
…
0x1 ……………………… MS TCP Loopback interface
…
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1

What could that be? Thanks

Are you running any sort of firewall or internet privacy software? Those things get in the way of the socket communications that the Eclipse debugger has to set up with the Tomcat VM and will result in errors precisely as you describe here. Some third-party hardware / software getting in the way of the debug connection is my bet at this point.
