> placeholders in endpoint properties
> -----------------------------------
>                 Key: ODE-619
>                 URL: https://issues.apache.org/jira/browse/ODE-619
>             Project: ODE
>          Issue Type: Improvement
>          Components: Axis2 Integration
>            Reporter: Alexis Midon
>            Assignee: Alexis Midon
>             Fix For: 1.3.3
> Endpoint properties [1] now support placeholders. These placeholders can be use in other
property values to avoid repeating common values. 
> The general placeholder pattern is ${placeholder.name}
> Three types of placeholders shall be separated:
>  #1  environment placeholders:  placeholders for environment variables. 
> They follow the naming convention ala ANT:  ${env.JAVA_HOME} will retrieve the JAVA_HOME
env var.
>  #2 system placeholders: placeholders for system properties
> They follow the naming convention: ${system.log4j.configuration} will access the system
property "log4j.configuration"
> System placeholders might point to environment placeholders.
>  #3 local placeholders: placeholders defined in one endpoint property file
> These do not use any prefixes: ${mytimeout} will be replaced by the value of "mytimeout"
> Local placeholder values might themselves used the 2 previous placeholders types (env
var and sys properties).
> mytimeout=${env.TIMEOUT} is valid, and will be replaced by the env variable TIMEOUT.
> Local placeholders can be defined in one file, and used in another. If defined twice,
the last loaded value will have precedence.
> Here are a few examples:
> placeholder1=placeholder1-value
> test.placeholder1=${placeholder1}
> ns-alias.my-service.ode.http.socket.timeout=${system.TestSystemProperty}
> ns-alias.my-service.ode.mex.timeout=${env.TEST_DUMMY_ENV_VAR}
> See org.apache.ode.utils.HierarchicalPropertiesTest for more.
