In the method... ZnNetworkingUtils >> streamClassForScheme: scheme scheme = #http ifTrue: [ ^ self socketStreamClass ]. scheme = #https ifTrue: [ ^ self secureSocketStreamClass ifNil: [ self error: 'No secure socket stream class set or available' ] ]. (ZnUnknownScheme scheme: scheme) signal I am getting the error indicating the lack fo secureSocketStreamClass. The initialize and lazy-initialization try to use ZdcSecureSocketStream, but that is not found. I am using Pharo 1.4 (downloaded & configured last summer) with Pier3 loaded, along with Zinc-HTTP (SvenVanCaekenberghe.280), Zinc-Path-HTTPSocket (StephaneDucasse.2) and Zinc-Seaside (SvenVanCaekenberghe.22). I see numerous updates to those and various other new packages. I believe what I have was pulled in by the following last summer: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPier3'; load. (Smalltalk at: #ConfigurationOfPier3) load. Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPier3AddOns'; load. (Smalltalk at: #ConfigurationOfPier3AddOns) load. - What is the recommended update approach for me, by those *in the know*? Thanks in advance, Cam
