Dear maintainer of SOAP::Lite I think we have discovered a rather severe bug in the way SOAP::Lite operates with WSDL files. I have 2 servers which both exposes the same service through their respective wsdl files. They both have the 'ping' command (which basically just returns the hostname of the server as a string) Individually they work as they should, but if you use them in the same program as shown below, it appears as if the service functions of the first SOAP instance gets overwritten with the ones of the second! My script looks like this: #!perl -w use SOAP::Lite; my $wsdl1 = 'https://celletest-15.energy.dtu.dk/wsdl/report.wsdl'; my $wsdl2 = 'https://celletest-11.energy.dtu.dk/wsdl/report.wsdl'; my $soap1 = SOAP::Lite->service($wsdl1); print "SOAP 1 ping: ",$soap1->ping,"\n"; my $soap2 = SOAP::Lite->service($wsdl2); print "SOAP 2 ping: ",$soap2->ping,"\n"; print "Recall ping on SOAP 1\n"; print "SOAP 1 ping: ",$soap1->ping,"\n"; And the expected output should be: [sqko@equipment-devel-01 ~]$ perl SOAP_test.pl SOAP 1 ping: celletest-15.energy.dtu.dk SOAP 2 ping: celletest-11.energy.dtu.dk Recall ping on SOAP 1 SOAP 1 ping: celletest-15.energy.dtu.dk However instead we get: [sqko@equipment-devel-01 ~]$ perl SOAP_test.pl SOAP 1 ping: celletest-15.energy.dtu.dk Subroutine _call redefined at (eval 134) line 111.

SOAP 2 ping: celletest-11.energy.dtu.dk Recall ping on SOAP 1 SOAP 1 ping: celletest-11.energy.dtu.dk As can be seen, the second call to $soap1->ping returns the result for $soap2 (and perl warns about redefining subroutines)!
