Examples of net.jini.activation.ActivatableInvocationHandler

net.jini.activation.ActivatableInvocationHandler

An invocation handler for activatable remote objects. If the client constraints of this activatable invocation handler are not null, then the invocation handler's underlying proxy (if any) must implement {@link RemoteMethodControl} or a remote invocationwill fail with an {@link UnsupportedConstraintException}. @author Sun Microsystems, Inc. @since 2.0 @com.sun.jini.impl This implementation recognizes the following system property:

com.sun.jini.activation.enableActivateGrant - This property is interpreted as a boolean value (see {@link Boolean#getBoolean Boolean.getBoolean}). If true, this implementation invokes {@link Security#grant(Class,Class) Security.grant}as defined in the specification.

This implementation's {@link #invoke invoke} method throws {@link IllegalArgumentException} if a remote invocation is to be made andthe proxy argument is an instance of an interface whose binary name is javax.management.MBeanServerConnection or any of the names produced by the following procedure:

For each resource named com/sun/jini/proxy/resources/InvocationHandler.moreProhibitedProxyInterfaces that is visible to the system class loader, the contents of the resource are parsed as UTF-8 text to produce a list of interface names. The resource must contain a list of binary names of interfaces, one per line. Space and tab characters surrounding each name, as well as blank lines, are ignored. The comment character is '#'; on each line, all characters starting with the first comment character are ignored.

This implementation uses the {@link Logger} namednet.jini.activation.ActivatableInvocationHandler to log information at the following levels:

Level	Description
{@link Levels#FAILED FAILED}	exception thrown from finalattempt to communicate a remote call
{@link Levels#FAILED FAILED}	exception thrown activatingthe object
