Description

Hello,

I've got following camel context definition:

<camelContext id="myContext" xmlns="http://camel.apache.org/schema/spring" trace="true">
        <camel:properties>
                <property key="http.proxyScheme" value="{{http.proxyScheme}}"/>
                <property key="http.proxyHost" value="{{http.proxyHost}}"/>
                <property key="http.proxyPort" value="8080"/>
        </camel:properties>

        <propertyPlaceholder id="properties" location="classpath:net.atos.acdwb.core.cfg"/>

        <routeBuilder ref="wallboardRoute" />
</camelContext>

Here the placeholders as defined in net.atos.acdwb.core.cfg:

# ...
http.proxyScheme=http
http.proxyHost=myHost
# ...

This file is available in the classpath as other spring placeholders are detected within the context file. Even so, I get following exception when attempting to run my unittest:

(...)
Caused by: java.lang.IllegalStateException: Scheme 'http.proxyscheme' not registered.
at org.apache.http.conn.scheme.SchemeRegistry.getScheme(SchemeRegistry.java:71)
at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:127)
(...)

According to Claus, placeholders are not supported on these Camel properties.

I thing it would be very helpful, though.

Thanks and regards,
Myriam
