Creating and using a web session
To set up a web session you need to do the following:
- Save a local session with the desired settings
- Transfer the local session file to the web server
- Add
web_session_name_x
and
web_session_url_x
applet parameters to the HTML page used to load JET.
- Set the value for the
web_session_url_x
parameter to the http: URL for the session file on the web server.
- Set the
last_web_session
applet parameter to the index of the highest
web_session_url_x
parameter.
Here is an example of how to create and use a web session.
The example assumes that your workstation is connected to the
Internet so that JET 3270 can connect to the Library of Congress
TN3270 server at locis.loc.gov.
If your workstation is not connected to
the Internet but can access a local TN3270
server then you should be
able to get similar results by substituting the hostname of the local
TN3270 server where locis.loc.gov appears.
- Start JET 3270 from the original Shortcut.htm file.
Note: Another web page can be used to start JET 3270 for this
example if the web page does not have any applet parameters
that start with
disable_
set to
yes.
- If JET 3270 is running within the browser window:
- Click the Close Session toolbar
button (trash can/garbage bin icon).
- Click New Window.
A JET 3270 window and Untitled Session
Settings dialog box appear.
- If a JET 3270 window appears but no Untitled Session Settings
dialog box appears:
- From the Session menu select Close.
- Click New Window.
A JET 3270 window and Untitled Session
Settings dialog box appear.
- If no JET 3270 window appears:
- Click New Window.
A JET 3270 window and Untitled Session
Settings dialog box appear.
- Enter locis.loc.gov
for Hostname on the
Untitled Session Settings dialog box.
- Click Colours in the Category list.
The Colours panel is displayed with
Cursor Colour selected.
- Click the Choose Colour button.
The Colour Selector dialog box appears.
- Select yellow from the list.
- Click OK on the Colour Selector dialog box.
The Colour Selector dialog box disappears. The
Cursor Colour square is yellow.
- Click Background Colour.
- Click the Choose Colour button.
- Select brown from the list.
- Click OK.
The Background Colour square is brown.
- Click Display in the Category list.
The Display panel is displayed.

- Click OK on the Session Settings dialog box.
The Session Settings dialog box disappears.
The background colour and screen keyboard on the JET
3270 window change. JET 3270 attempts to
connect to the host.
- Select Save As... from the Session menu.
A Save Session As dialog box appears.
- Enter _session_name for the session name.
- Click Save.
- Select Close from the Session menu.
The JET 3270 window disappears.
- Locate the local session directory.
The location of the local session directory depends on the web
browser and operating system:
- Communicator
- Windows 98
If Communicator was installed in the default directory
then the local session directory is:
C:\Program
Files\Netscape\Users\user\.jet3270
where user is the profile name.
- Solaris, HP-UX, Linux and AIX
The local session directory is:
~/.netscape/.jet3270
- Internet Explorer
- Windows 98
- Microsoft VM
If Windows was installed in the default directory, then
the local session directory is:
C:\WINDOWS\JAVA\.jet3270
- Java Plug-in
If Windows was installed in the default directory, then
the local session directory is:
C:\WINDOWS\.jet3270
- Mac OS X
The local session directory is a folder called .jet3270
in the user's home folder. It is not visible from the Finder.
- Netscape 6
- Windows 98
If Windows 98 was installed in the default directory, then
the local session directory is:
C:\WINDOWS\.jet3270
The general rule is that the local session directory is called
.jet3270 and is a subdirectory of the user's
home directory as given by
the browser (i.e. the user.home system property).
- Locate the _session_name session file. It is in the local
session directory and named "_session_name".
- Transfer the _session_name session file to your web server
as a binary file. The way of doing this will depend on
your environment. Alternatively copy the session file to
another directory on you local file system. For example,
C:\ on a Windows system or your home directory on a Unix
machine.
- Determine the fully quailified URL that will access the
session file on the web server. For example, if your web
server's name was intranet.acme.com and you had transfered
the session file to a jet/session subdirectory of the web
server's document root directory then the URL might be:
http://intranet.acme.com/jet/session/_session_name
If you copied the session file to the C:\ directory on
your Windows system the URL is:
file:/C:/_session_name
If you copied the session file to a /home/myuser directory
on your Unix system the URL is:
file:///home/myuser/_session_name
- Copy the original Shortcut.htm file to WebSession.html
- Open WebSession.html with a text editor. Delete the line that
starts with:
<param name="last_web_session" ...
and add the following lines in its place:
<param name="web_session_name_0"
value="_session_nameWeb">
<param name="web_session_url_0"
value="url">
<param name="last_web_session"
value="0">
Substitute the URL that will access the session file where
url appears. Save these changes.
- Restart JET 3270 from the WebSession.html file.
- If JET 3270 is running within the browser window:
- Click the Close Session toolbar
button (trash can/garbage bin icon).
- Click the Open Session in New Window button.
An Open Session dialog box appears.
- Click _session_nameWeb in the Web list.
- Click Open.
A JET 3270 window appears with the title
"_session_nameWeb - JET 3270", a brown
background colour and screen keyboard buttons in a
large Times Roman font.
JET 3270 attempts to connect to
locis.loc.gov
. If it
connects successfully
the LOCIS main screen
is displayed with a
yellow cursor.
