/**
* Standalone XML application context, taking the context definition
* files from the class path. Mainly useful for test harnesses,
* but also for application contexts embedded within JARs.
*
* Treats resource paths as class path resources, when using
* getResource. Only supports full class path resource
* names that include the package path, like "mypackage/myresource.dat".
*
*
The config location defaults can be overridden via setConfigLocations,
* Config locations can either denote concrete files like "/myfiles/context.xml"
* or Ant-style patterns like "/myfiles/*-context.xml" (see PathMatcher javadoc for
* pattern details).
*
*
Note: In case of multiple config locations, later bean definitions will
* override ones defined in earlier loaded files. This can be leveraged to
* deliberately override certain bean definitions via an extra XML file.
