35 /** |
|
36 * MailcapCommandMap extends the CommandMap |
|
37 * abstract class. It implements a CommandMap whose configuration |
|
38 * is based on mailcap files |
|
39 * (<A HREF="http://www.ietf.org/rfc/rfc1524.txt">RFC 1524</A>). |
|
40 * The MailcapCommandMap can be configured both programmatically |
|
41 * and via configuration files. |
|
42 * <p> |
|
43 * <b>Mailcap file search order:</b><p> |
|
44 * The MailcapCommandMap looks in various places in the user's |
|
45 * system for mailcap file entries. When requests are made |
|
46 * to search for commands in the MailcapCommandMap, it searches |
|
47 * mailcap files in the following order: |
|
48 * <p> |
|
49 * <ol> |
|
50 * <li> Programatically added entries to the MailcapCommandMap instance. |
|
51 * <li> The file <code>.mailcap</code> in the user's home directory. |
|
52 * <li> The file <<i>java.home</i>><code>/lib/mailcap</code>. |
|
53 * <li> The file or resources named <code>META-INF/mailcap</code>. |
|
54 * <li> The file or resource named <code>META-INF/mailcap.default</code> |
|
55 * (usually found only in the <code>activation.jar</code> file). |
|
56 * </ol> |
|
57 * <p> |
|
58 * <b>Mailcap file format:</b><p> |
|
59 * |
|
60 * Mailcap files must conform to the mailcap |
|
61 * file specification (RFC 1524, <i>A User Agent Configuration Mechanism |
|
62 * For Multimedia Mail Format Information</i>). |
|
63 * The file format consists of entries corresponding to |
|
64 * particular MIME types. In general, the specification |
|
65 * specifies <i>applications</i> for clients to use when they |
|
66 * themselves cannot operate on the specified MIME type. The |
|
67 * MailcapCommandMap extends this specification by using a parameter mechanism |
|
68 * in mailcap files that allows JavaBeans(tm) components to be specified as |
|
69 * corresponding to particular commands for a MIME type.<p> |
|
70 * |
|
71 * When a mailcap file is |
|
72 * parsed, the MailcapCommandMap recognizes certain parameter signatures, |
|
73 * specifically those parameter names that begin with <code>x-java-</code>. |
|
74 * The MailcapCommandMap uses this signature to find |
|
75 * command entries for inclusion into its registries. |
|
76 * Parameter names with the form <code>x-java-<name></code> |
|
77 * are read by the MailcapCommandMap as identifying a command |
|
78 * with the name <i>name</i>. When the <i>name</i> is <code> |
|
79 * content-handler</code> the MailcapCommandMap recognizes the class |
|
80 * signified by this parameter as a <i>DataContentHandler</i>. |
|
81 * All other commands are handled generically regardless of command |
|
82 * name. The command implementation is specified by a fully qualified |
|
83 * class name of a JavaBean(tm) component. For example; a command for viewing |
|
84 * some data can be specified as: <code>x-java-view=com.foo.ViewBean</code>.<p> |
|
85 * |
|
86 * When the command name is <code>fallback-entry</code>, the value of |
|
87 * the command may be <code>true</code> or <code>false</code>. An |
|
88 * entry for a MIME type that includes a parameter of |
|
89 * <code>x-java-fallback-entry=true</code> defines fallback commands |
|
90 * for that MIME type that will only be used if no non-fallback entry |
|
91 * can be found. For example, an entry of the form <code>text/*; ; |
|
92 * x-java-fallback-entry=true; x-java-view=com.sun.TextViewer</code> |
|
93 * specifies a view command to be used for any text MIME type. This |
|
94 * view command would only be used if a non-fallback view command for |
|
95 * the MIME type could not be found.<p> |
|
96 * |
|
97 * MailcapCommandMap aware mailcap files have the |
|
98 * following general form:<p> |
|
99 * <code> |
|
100 * # Comments begin with a '#' and continue to the end of the line.<br> |
|
101 * <mime type>; ; <parameter list><br> |
|
102 * # Where a parameter list consists of one or more parameters,<br> |
|
103 * # where parameters look like: x-java-view=com.sun.TextViewer<br> |
|
104 * # and a parameter list looks like: <br> |
|
105 * text/plain; ; x-java-view=com.sun.TextViewer; x-java-edit=com.sun.TextEdit |
|
106 * <br> |
|
107 * # Note that mailcap entries that do not contain 'x-java' parameters<br> |
|
108 * # and comply to RFC 1524 are simply ignored:<br> |
|
109 * image/gif; /usr/dt/bin/sdtimage %s<br> |
|
110 * |
|
111 * </code> |
