How to access system property in blueprint xml?

[jasonnh]

Hi,

I have a camel context and beans defined in a blueprint xml file and would like to access a system property.

I would like the blueprint equivalent of spring:

${com.company.myProperty}

e.g.

Does anybody know of a way of doing this in blueprint?

Many thanks.

Hi,

To use system properties in Blueprint, you should use blueprint-ext.

something like:

Thanks Freeman.

Do you know how can I combine that with getting other properties from a properties file on the classpath to be used in a camel context?

The following works without the ext:property-placeholder but not combined with it - it fails to find the camelProperty property (defined in some.properties file).  Trying to use classpath: prefix in location tag of ext:property-placeholder does not work either.

Any ideas much appreciated.

My original question has been answered - thanks again.

In case this can help someone I think the problem I am having with mixing property placeholders is a bug that is fixed in camel 2.10.0 (undocumented in the release notes), i.e.:

BlueprintPropertiesPlaceholder.parseProperty method has changed.  Basically, 2.9.0 uses a parameter called 'value' as a local variable which gets set to null and then passes that to delegate.parseProperty as if it was unchanged.  2.10.0 declares a separate local variable 'answer' and then passes the orignal 'value' to delegate.parseProperty.

I have logged a ticket to get this backported to Fuse 7.0.x
