	 * This method invokes a remote method on an object on the server side that can be specified with a key path (no
	 * enterprise object) relative to the invocation target of the server side EODistributionContext (for example
	 * "session"). The arguments and return values of remote methods invoked through this method cannot be enterprise
	 * objects (but global IDs are okay). You can use this method, for example, to load resources from the server or to
	 * perform checks in background threads (as long as no enterprise objects are involved).
	 * <p>
	 * The keyPath argument has special semantics: <ol type="a"}
	 * <li>If keyPath is a fully qualified key path (for example, "session"), the key path is followed starting from the
	 * invocation target of the EODistributionContext.
	 * <li>If keyPath is an empty string, the method is invoked on the invocation target of the EODistributionContext
	 * directly (typically a subclass of WOJavaClientComponent).
	 * <li>If keyPath is null, the method is invoked on one of the remote method receivers of the server side
	 * EODistributionContext. </ol>
	 * <p>
	 * If an actual key path is specified, the EODistributionContext on the server blocks all invocations sent with this
	 * method unless methodName is prefixed with "clientSideRequest" or unless the EODistributionContext's delegate (on
	 * the server) implements the right delegate methods to explicitly allow the invocation. "clientSideRequest" methods
	 * can be invoked without special delegate methods on the server-side distribution context, on a remote method
	 * receiver registered with the distribution context or on the session of the distribution context's invocation
	 * target.
	 * 
	 * @param keyPath
	 *            the key path identifying the receiver of the method invocation
	 * @param methodName
