Hi Geoff
Sorry to bother you again.
I have a question about blueprinting and using brooklyn.parameters
I managed to write a long winded application with a couple of services
which are like a cluster, but written out fully. That works fine.
Now I'm trying to abstract out the entity to put in the catalog and
template three variables which need to differ between one instance of the
entity and another.
I could be misusing the syntax, but the error message I'm getting is so
vague, I don't know where to look for my problem: Here's the definition
of the entity. As you can see, I need the templated name to occur in a
bunch of spots
*first... in the deployment, I'm hoping to do something like this*
services:
- type: htclienttemplate
clientname: ht1
jmxport: 19001
resturl: "
http://127.0.0.1:8081/v1/applications/infocommons/entities/ht1/sensors";
- type: htclienttemplate
clientname: ht2
jmxport: 19001
resturl: "
http://127.0.0.1:8081/v1/applications/infocommons/entities/ht2/sensors";
*And this is what I'm trying to add to the catalog. *
brooklyn.catalog:
id: htclienttemplate
version: "1.1"
itemType: entity
item:
name: $brooklyn:config("clientname")
location: localhost
type: org.apache.brooklyn.entity.java.VanillaJavaApp
brooklyn.config:
run.dir: /Users/peterabramowitsch/manhattan
children.startable.mode: FOREGROUND

vanillaJavaApp.jvmDefines:

serveraddr: mongodb://localhost:27017
log4j.configurationFile: config/log4j-datacommons.xml
log4jid: $brooklyn:config("clientname")
brooklyn.credentials: xxxxxxxxxxx
brooklyn.resturl: $brooklyn:config("resturl")
jmx.direct.port: $brooklyn:config("jmxport")
brooklyn.parameters:
- name: clientname
- name: jmxport
- name: resturl
I can't interpret the error I'm getting.......
ERROR
