unable read repository @ http://pydev.sf.net/updates/content.xml. sun.security.validator.validatorexception: pkix path building failed:   sun.security.provider.certpath.suncertpathbuilderexception: unable find   valid certification path requested target

i installing pydev in eclipse using python, doesn't install successfully. gives above error. happened? how solve error?

i had error when trying install on laptop behind corporate firewall. couldn't tell setup of firewall, not sure of root cause.

i got passed error installing pydev eclipse when out behind firewall.

another way got around have eclipse on non-firewalled machine, install pydev eclipse, , copy whole eclipse directory non-firewalled machine firewalled machine.

there better way, , way fix properly, didn't have time work out firewall doing.

this on windows 7 machine (yeah know) not work *nix versions installed through package manager yum or apt.
