showPage
The class
attribute of the showPage
tag should map to oracle.portal.provider.v2.sample.AppletRenderer
class.
useQuickLoader
This tag is used to indicate if a splash screen is required while the
applet download is in progress. This tag can only accept values true
or false:
- True indicates that the splash screen with images and/or messages
should be shown while downloading the
actual applet.
- False value indicates that the splash
screen is not required.
showStatus
This tag is only effective if <useQuickLoader>
is set to true. Quick Loader brings a status bar while showing the
splash screen, where the status of the download is visible.
splashImage
This tag is only effective if <useQuickLoader>
is set to true. This contains the absolute/relative location
of the image which needs to be shown while the download is in progress.
If an absolute path is specified, the path is mapped from the current
mid-tier's context path.
message
This tag is only effective if <useQuickLoader>
is set to true. This contains the message which needs to be
shown while the download is in progress.
The portlet also contains another tag called <appletDescriptor>
which describes the Tn3270 applet details, it contains the following set
of tags:
<appletDescriptor class="oracle.portal.provider.v2.sample.AppletDescriptor">
<name>Tn3270 Client</name>
<description>This is the Tn3270 Mainframe's Client.</description>
<code>oracle.portal.integration.tn3270.Tn3270Applet.class</code>
<codebase>/WEB-INF/lib</codebase>
<archive>tn3270.jar,appletviewer.jar</archive>
<usePlugin>false</usePlugin>
<width>650</width>
<height>400</height>
<paramDescriptor class="oracle.portal.provider.v2.sample.ParamDescriptor">
<name>hostmane</name>
<value>some Hostname</value>
</paramDescriptor>
<appletDescriptor>
appletDescriptor
The class
attribute of this tag should map to the oracle.portal.provider.v2.sample.AppletDescriptor
class
name
This tag gives a name to the applet while it is rendered in the browser.
This name can be used by the javascript for communication
with the applet. The browser will interpret this name, just as it interprets as any other component
name.
description
This tag gives provides a description of the applet. The description text will be shown
if the applet could not be interpreted by the browser.
code
This is a mandatory tag, this specifies the full qualified name
of the applet class. The Tn3270 Applet's class is oracle.portal.integration.tn3270.Tn3270Applet
codebase
This is an optional tag, that specifies the location from where
the applet code (jar) can be downloaded. You can specify the relative URL,
from the current context path. For example /htdocs/jars
specifies physical path will be relative to the current context path, which
will resolve to the following directory structure:
$IAS_HOME(MID_TIER)/j2ee/OC4J_PORTAL/applications/tn3270/tn3270/htdocs/jars.
archive
This is another mandatory tag, that specifies the download jar file to run the applet. You can specify more than one jar/zip
files separated by commas (,). The Tn3270's jar file name
is tn3270.jar.
If you have set the <quickLoader>
to true, then you should also make an entry for appletviewer.jar
in the archive
tag. Subsequently you should make sure the jar file is available through
the codebase for a successful download. The appletviewer.jar
file in available in the /WEB-INF/lib
directory of the context path.
NOTE: The appletviewer.jar
file is present at the following location when the Tn3270 Application is
deployed on OC4J. $IAS_HOME(MID_TIER)/j2ee/OC4J_PORTAL/applications/tn3270/tn3270/htdocs/jars.
The appletviewer.jar renders the applet as a portlet.
usePlugin
This is an optional tag. This Boolean tag indicates whether
the Appletviewer should use the plugin or use the browser based JVM to render
the portlet in the browser:
- True indicates that the portlet should be rendered using an applet plugin.
- False indicates that the portlet can run
using the browser based JVM. The default is False.
width
This is a mandatory tag, that indicates the width to be occupied
by the portlet on the browser window.
height
This is a mandatory tag. This tag specifies the height to
be occupied by the portlet on the browser window.
paramDescriptor
This is an optional tag. This tag is used to supply some initial parameters/arguments
to the applet (running in the portlet) for its initialization. Every
parameter has to be specified in a separate <paramDescriptor>
tag. The class
attribute of this tag must map to the oracle.portal.provider.v2.sample.ParamDescriptor
class. The name & value parameters can be supplied in the child tags <name>
& <value>
respectively.
The Tn3270 Applet requires the hostname
parameter. This parameter is Mandatory. This tag takes in the name
or IP address of the Tn3270 Mainframe machine to which the user wants to
connect to.
