[Swift-devel] Example of wrapper staging?

[Michael Wilde]

I get this error:

org.griphyn.vdl.util.SwiftConfigException: swift.conf:4 unexpected 
property 'site.local.wrapperStagingLocalServer'
     at 
org.griphyn.vdl.util.SwiftConfigSchema.validate(SwiftConfigSchema.java:214)

Ive tried spelling this property both as in your sample .conf and as in 
your text:

wrapperStagingLocalServer and wrapperStageingLocalServer

Neither is accepted.  Did a schema change not get committed?

For general info: where is the json schema file that a user can check to 
find all valid conf parameters?

Thanks,

- Mike
