Usage

From source file:com.bedatadriven.renjin.appengine.AppEngineContextFactory.java

@VisibleForTesting
static FileSystemManager createFileSystemManager(LocalFileProvider localFileProvider)
        throws FileSystemException {
    try {//w ww  .  ja  v  a  2  s . com
        JarFileProvider jarFileProvider = new AppEngineJarFileProvider();

        // this provides a fake local file system rooted in the servlet context root.
        // this is necessary because on the actual appengine platform, any queries to the ancestors
        // of the servlet context (e.g. /base) will throw a security exception

        DefaultFileSystemManager dfsm = new DefaultFileSystemManager();
        dfsm.addProvider("jar", jarFileProvider);
        dfsm.addProvider("file", localFileProvider);
        dfsm.addExtensionMap("jar", "jar");
        dfsm.setDefaultProvider(new UrlFileProvider());
