Re: ISA not working as expected in SOAP::Lite servlets

Hi Paul,

You may want to change that to 'package Test::Root;'. Everything seems to
be working after that.

yes, these are two alternatives.

You may do something like this:

# go to server 1
my $myob=$remoteserver->createObject();
print $myob->foo();

# SOAP::Lite->self returns SOAP::Lite object that does autodispatch, so
you can get/set any properties on that object as you would usually do
SOAP::Lite->self->endpoint("http://foo/");

# go to server 2
my $myob=$remoteserver->createObject();
print $myob->foo();

Hope it helps.

Best wishes, Paul.
