The package contains an aggregator class called <tt>Dispatcher</tt>which includes methods to add services to its registry, dispatch APDUcommands to registered services, and remove services from its registry.</p><p>The package also contains the <tt>Service</tt> interface whichcontains methods to process APDU commands, and allow the dispatcher tobe aware of multiple services. Subinterfaces allow an implementationservices with added functionality: </p><ul> <li><tt>RemoteService</tt>-use this subinterface to define servicesthat allow remote processes to access the services present on a cardthat supports the Java Card platform.</li> <li><tt>SecurityService</tt>-use this subinterface to define servicesthat provide methods to query the current security status.</li></ul><p>The class <tt>BasicService</tt> provides the basic functionality ofa service, and all services are built as subclasses of this class. <tt>BasicService</tt>provides a default implementation for the methods defined in the <tt>Service</tt>interface, and defines a set of helper methods that allow the APDUbuffer to enable cooperation among different services.</p><h2>RMI Classes for the Java Card Platform</h2><p>The <tt>CardRemoteObject</tt> and <tt>RMIService</tt> classesallow a Java programming language program running on a virtual machineon the client platform to invoke methods on remote objects in a JavaCard technology-based applet. These classes contain the minimumrequired functionality to implement Remote Method Invocation for theJava Card platform (RMI for the Java Card platform). </p><p> </p><P><P><DL></DL><HR><!-- ======= START OF BOTTOM NAVBAR ====== --><A NAME="navbar_bottom"><!-- --></A><A HREF="#skip-navbar_bottom" title="Skip navigation links"></A><TABLE BORDER="0" WIDTH="100%" CELLPADDING="1" CELLSPACING="0" SUMMARY=""><TR><TD COLSPAN=2 BGCOLOR="#EEEEFF" CLASS="NavBarCell1"><A NAME="navbar_bottom_firstrow"><!-- --></A><TABLE BORDER="0" CELLPADDING="0" CELLSPACING="3" SUMMARY=""> <TR ALIGN="center" VALIGN="top"> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../overview-summary.html"><FONT CLASS="NavBarFont1"><B>Overview</B></FONT></A> </TD> <TD BGCOLOR="#FFFFFF" CLASS="NavBarCell1Rev"> <FONT CLASS="NavBarFont1Rev"><B>Package</B></FONT> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <FONT CLASS="NavBarFont1">Class</FONT> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-use.html"><FONT CLASS="NavBarFont1"><B>Use</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-tree.html"><FONT CLASS="NavBarFont1"><B>Tree</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../deprecated-list.html"><FONT CLASS="NavBarFont1"><B>Deprecated</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../index-all.html"><FONT CLASS="NavBarFont1"><B>Index</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../help-doc.html"><FONT CLASS="NavBarFont1"><B>Help</B></FONT></A> </TD> </TR></TABLE></TD><TD ALIGN="right" VALIGN="top" ROWSPAN=3><EM><b>Java Card </b><br><font size="-1">v2.2.2</font></EM></TD></TR><TR><TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> <A HREF="../../../javacard/framework/package-summary.html"><B>PREV PACKAGE</B></A> <A HREF="../../../javacard/security/package-summary.html"><B>NEXT PACKAGE</B></A></FONT></TD><TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> <A HREF="../../../index.html?javacard/framework/service/package-summary.html" target="_top"><B>FRAMES</B></A> <A HREF="package-summary.html" target="_top"><B>NO FRAMES</B></A> <SCRIPT type="text/javascript"> <!-- if(window==top) { document.writeln('<A HREF="../../../allclasses-noframe.html"><B>All Classes</B></A>'); } //--></SCRIPT><NOSCRIPT> <A HREF="../../../allclasses-noframe.html"><B>All Classes</B></A></NOSCRIPT></FONT></TD></TR></TABLE><A NAME="skip-navbar_bottom"></A><!-- ======== END OF BOTTOM NAVBAR ======= --><HR><i>Copyright © 1993-2005 Sun Microsystems, Inc. 4150 Network Circle,<br>Santa Clara, CA, 95054, U.S.A.
