|

|
|
<div><p>For Java™ plug-ins, iSeries™ Navigator
|
||
|
|
provides a built-in ActiveX server that manages the communication between the Navigator and the plug-in's Java classes.</p>
|
||
|
|
<p>The server component uses the Java Native Interface (JNI) API to create the plug-in's objects and to call their
|
||
|
|
methods. Thus, Java programmers who are developing iSeries Navigator plug-ins do not need to be concerned with the details of ActiveX server implementation.</p>
|
||
|
|
<p>When a user is interacting with iSeries Navigator Java plug-ins,
|
||
|
|
calls will be generated to the different registered Java interface classes for the implementation of the specific
|
||
|
|
request.</p>
|
||
|
|
<p>Plug-ins work by responding to method calls from iSeries Navigator that are generated in response to user actions. For
|
||
|
|
example, when a user right-clicks on an object in the Navigator hierarchy, the Navigator constructs a context menu for the object, and displays the menu on the screen. The Navigator obtains the menu items
|
||
|
|
by calling each plug-in that has registered its intent to supply context menu items for the selected object type.</p>
|
||
|
|
<p>The functions that are implemented by a plug-in logically are grouped into "interfaces." An interface is a set of logically related methods on a class that iSeries Navigator can call to perform a specific function. For Java plug-ins, the
|
||
|
|
following three <span class="uicontrol">Java interfaces</span> are defined:</p>
|
||
|
|
<ul><li>ListManager</li>
|
||
|
|
<li>ActionsManager</li>
|
||
|
|
<li>DropTargetManager</li>
|
||
|
|
</ul>

<dl><dt class="dlterm">Product architecture for iSeries Navigator plug-ins</dt>
|
||
|
|
<dd><p><strong>The internal architecture of the iSeries Navigator product reflects that it is intended to serve as an integration
|
||
|
|
point for an extensible, broad-based operations interface for the iSeries server. Each functional component of the interface
|
||
|
|
is packaged as an ActiveX server. The Navigator learns about the existence of a particular server component by means of entries in the Windows<sup>®</sup> registry. Multiple servers may register their request to add menu items and dialogs to a given object type in the Navigator hierarchy.</strong></p>

<div class="note"><span class="notetitle">Note:</span> <strong>For third-party Java plug-ins to be available to iSeries Navigator
|
||
|
|
users, iSeries Access for Windows users
|
||
|
|
must have Version 4 Release 4 Modification Level 0 of iSeries Access for Windows installed on their personal computers.</strong></div>

</dd>
|
||
|
|
<dt class="dlterm">iSeries Navigator data for Java plug-ins</dt>
|
||
|
|
<dd> <p>When the Navigator calls a function implemented by a plug-in, the request typically involves an object or objects the user selected in the main Navigator window. The plug-in must be able to determine
|
||
|
|
which objects have been selected. The plug-in receives this information as a list of fully-qualified object names. For Java plug-ins,
|
||
|
|
an ObjectName class is defined that provides information about the selected objects. Plug-ins that add folders to the object hierarchy must return items in the folder to iSeries Navigator in the form of "item identifiers." For Java plug-ins, an ItemIdentifier
|
||
|
|
class is defined that is used by the plug-in to return the requested information.</p>
|
||
|
|
<p>An iSeries Navigator plug-in sometimes
|
||
|
|
will need to affect the behavior of the main Navigator window. For example, following completion of a user operation, it may be necessary to refresh the Navigator list view or to insert text into the Navigator's
|
||
|
|
status area. Utility classes are supplied in the package com.ibm.as400.opnav that provide the required services.</p>
