In part 1, serve-side is tornadows, the axis2-client cannot invoke the server, and returns nothing In part 2, server-side is soaplib. the server is developed in ubuntu linux,"172.16.2.46" is its ip, when you exceute "w3m http://localhost:7789/?wsdl";, "w3m http://127.0.0.1:7789/?wsdl";, thay are okay. but "w3m: Can't load http://172.16.2.46:7789/?wsdl."; is failed. I develop tornadows in the same ubuntu linux, "w3m http://172.16.2.46:8000/SMSService?wsdl"; is also okay. In the local area network, "http://172.16.2.46:8000/SMSService?wsdl"; is also okay. I do not know the difference of tornadows and soaplib, so sent them together. w_jiaxiaolei@pabb-608:~$ ifconfig eth0 Link encap:Ethernet HWaddr 1c:6f:65:d4:b3:d3 inet addr:172.16.2.46 Bcast:172.16.255.255 Mask:255.255.0.0 inet6 addr: fe80::1e6f:65ff:fed4:b3d3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2538292 errors:0 dropped:0 overruns:0 frame:0 TX packets:979243 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:276531149 (276.5 MB) TX bytes:621990155 (621.9 MB) Interrupt:32 Base address:0xa000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2619 errors:0 dropped:0 overruns:0 frame:0 TX packets:2619 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:410554 (410.5 KB) TX bytes:410554 (410.5 KB) w_jiaxiaolei@pabb-608:~$ w3m http://172.16.2.46:8000/SMSService?wsdl w_jiaxiaolei@pabb-608:~$ w3m http://127.0.0.1:7789/?wsdl w_jiaxiaolei@pabb-608:~$ w3m http://localhost:7789/?wsdl w_jiaxiaolei@pabb-608:~$ w3m http://172.16.2.46:7789/?wsdl w3m: Can't load http://172.16.2.46:7789/?wsdl.
