-----------------------------------
Summary: InstanceService and Placeholder
Key: KARAF-3354
URL: https://issues.apache.org/jira/browse/KARAF-3354
Project: Karaf
Issue Type: Bug
Components: karaf-core
Affects Versions: 3.0.2
Reporter: Kai Reichert
Priority: Minor
The configuration file 'etc/org.apache.karaf.management.cfg' can be used to
change the RMI ports and addresses.
In this file and every other *.cfg file you can use placeholders, which may be
defined in the 'etc/custom.properties' file.
For example you can change the key rmiRegistryPort to:
rmiRegistryPort = ${my.custom.rmi.port}
Then 'my.custom.rmi.port' has to be defined in 'etc/custom.properties' like:
my.custom.rmi.port = 1100
This works perfectly. What does not work are karaf's shell command like
'instance:list'.
If you invoke this command with the placeholder customization you get the error
message:
karaf@root()> instance:list
Error executing command: For input string: ""
If I try to debug it, I end up in the class InstanceServiceImpl inside the
method getKarafPort().
The Properties object this method gets, has an empty value for rmiRegistryPort.
It seems as this placeholder is not ”interpolated” correctly.
The karaf instance itself is correctly binded at port 1100 instead of 1099.
