Hi All
I have created a small secrets provider and unit tested it on it's own
first. But I am having an issue with Brooklyn loading up my class and its
dependencies.
Following the instructions, I put the class file into a new dropins folder
inside lib. And added a call to the provider in brooklyn.cfg
>> brooklyn.external.ucsfsecrets=org.ucsf.ctakes_auth.UcsfSecretsProvider
I then put the class's dependent jars in the lib/boot folder. Not sure
whether they should be there or in lib itself... because I'm not sure which
classloader the dropins will be using
Because I wasn't sure what dropins was expecting, I put the class in twice,
as you see
lib/dropins
├── UcsfSecretsProvider.class
└── org
└── ucsf
└── ctakes_auth
└── UcsfSecretsProvider.class
My provider needs a couple of JVM defines, so I added these to the setenv
script.
On startup, the exception blew up the launch of the Brooklyn container
My error message is this Exception ( I put the entire trace at the bottom
of this message)
....

o.a.b.c.m.i.BasicExternalConfigSupplierRegistry [FelixStartLevel] Failed to

java.lang.ClassNotFoundException: Class
org.ucsf.ctakes_auth.UcsfSecretsProvider not found on the application class

The exception mentions a "bundle whitelist" which I don't see among any of
the config files in $BROOKLYN_HOME/etc. I also looked at the unit test
for drop-ins in the Brooklyn source, but was unable to relate that to my
situation.
Clearly there is more to a custom provider than I see in the
documentation. Do you have any more information to help me out?
Many thanks in advance, Peter
