Usage

From source file:org.apache.axis.configuration.EngineConfigurationFactoryFinder.java

/**
 * Create the default engine configuration and detect whether the user
 * has overridden this with their own.//  www . ja v  a2 s.co m
 *
 * The discovery mechanism will use the following logic:
 *
 * - discover all available EngineConfigurationFactories
 *   - find all META-INF/services/org.apache.axis.EngineConfigurationFactory
 *     files available through class loaders.
 *   - read files (see Discovery) to obtain implementation(s) of that
 *     interface
 * - For each impl, call 'newFactory(Object param)'
 * - Each impl should examine the 'param' and return a new factory ONLY
 *   - if it knows what to do with it
 *     (i.e. it knows what to do with the 'real' type)
 *   - it can find it's configuration information
 * - Return first non-null factory found.
 * - Try EngineConfigurationFactoryServlet.newFactory(obj)
 * - Try EngineConfigurationFactoryDefault.newFactory(obj)
 * - If zero found (all return null), throw exception
 *
 * ***
 * This needs more work: System.properties, etc.
 * Discovery will have more tools to help with that
 * (in the manner of use below) in the near future.
 * ***
