A method including: receiving at a server a first request from a first provider to retrieve a first configuration for a first lookup order; determining the first configuration for the first lookup order using the server based at least in part on both an ordering specified by the first lookup order and the first call being through the direct dependency relationship; providing the first configuration to the first provider; receiving at the server a second request from the first provider to retrieve a second configuration for a second lookup order; determining the second configuration for the second lookup order using the server based at least in part on both an ordering specified by the second lookup order and the second call to the first provider by the application being through the transitive dependency relationship; and providing the second configuration to the first provider. Other embodiments are described.

Configuration resolution for transitive dependencies

A method including receiving on a server a request from a first provider to retrieve a configuration for a lookup order. The method also can include determining the configuration for the lookup order using the server based at least in part on whether the call to the first provider by the application is through the direct dependency relationship or through the transitive dependency relationship. The method further can include providing the configuration for the lookup order to the first provider. The method additionally can include receiving first information at the application that is based at least in part on the configuration for the lookup order. The method further can include providing second information for at least a portion of a web page that is based at least in part on the first information. Other embodiments are provided.

The present invention is generally directed to methods, systems, and computer program products for configuring applications at runtime. Embodiments of the invention decouple code and configuration. Application configuration is externalized, allowing configuration to be composed at runtime based on client context. A client context for an application is sent to a configuration manager. One or more pluggable configuration providers at the configuration manager deduce values for use in configuring the application at runtime. Deduced values are composed into a configuration and the configuration returned to the application. Using the values in the composed configuration, the application can be configured to operate in the client context.
