This page has instructions explaining how to perform some important
JET 3270 tasks.
The JET 3270 Documentation
has further information about installing, configuring and using JET
3270.
Creating a new preferences set and a host
entry using it
Here is an example of how to create a new preference set, change it
and create a host entry using it.
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 you 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
disable_connect or
disable_new_window set to
yes.
- If JET 3270 is running within the browser window (i.e. a JET 3270
window did not appear):
- If the Connect dialog box appears:
- Click Cancel on the Connect dialog box.

3270". JET 3270 attempts to connect to
locis.loc.gov
. If it
connects successfully
the LOCIS main screen
is displayed with a
yellow cursor.
Starting a Debug Log
Here are instructions on how to make a debug log of a
JET 3270 session. The debug log is used to determine the
cause of a JET 3270 problem.
Microsoft Internet Explorer
Start Microsoft Internet Explorer.
Enable
JavaTM
logging in Internet Explorer. To do this, from the View
menu select "Internet Options...". On the "Advanced"
tab click the "Java logging enabled" checkbox to place
a tick there.
Start JET 3270 by loading the Shortcut.htm web page
provided in the applet directory of the JET 3270
distribution. When you see the Security Warning dialog
box, click on "Yes".
You will see a Connect dialog box. Do
NOT type a host name yet.
Click on the "File" menu in the main JET
window. Click on "Log Debug Data". This activates JET
3270's debug logging function.
Now type the name of the 3270 host and click
"OK". You will see that host's login screen or a similar
host welcome screen.
Logon to your 3270 host system and recreate the JET
3270 problem scenario you are experiencing.
After the problem you've identified has occurred,
select "Disconnect" from the "Connection" menu in the
in the JET 3270 main window.
Internet Explorer writes the Java log to javalog.txt.
For Windows 95 & 98 it is in C:\windows\java
For Windows NT it is in C:\winnt\java
Using Windows Explorer or the MS-DOS Prompt make a copy
of the javalog.txt file. (Some programs do not read the
log correctly from the original javalog.txt file,
making a copy avoids this problem.)
Netscape Communicator
Start Communicator.
Select "Java Console" from the "Communicator"
menu (it may be on the "Tools" submenu). Communicator's
Java Console will appear.
Start JET 3270 by loading the Shortcut.htm web page
provided in the applet directory of the JET 3270
distribution. When you see the Java Security windows,
click on "Grant".
You will see a Connect dialog box. Do
NOT type a host name yet.
Click on the "File" menu in the main JET
window. Click on "Log Debug Data". This activates JET
3270's debug logging function.
Now type the name of the 3270 host and click
"OK".
You will see a Java Security window, click on
"Grant".
You will see the host's login screen or a similar
host welcome screen.
Logon to your 3270 host system and recreate JET
3270 problem scenario you are experiencing. You will
see data flowing between JET 3270 and the host being
logged in the Java Console. If the Java Console becomes
full data will no longer be logged. If this happens,
press the "Clear" button on the Java Console so that
new data will continue to be logged.
After the problem you've identified has occurred,
scroll up to the top of the Java Console. Drag the
mouse from the start of the data logged to the
end. Press Ctrl-C to copy the data to the
clipboard.
Start Notepad (or a text editor). Paste the data
logged from the clipboard into the Notepad window. Save
the data to a file.
Please create an email message, attach the log file,
and send it to us at:
jetsupport@platypuspartners.com
You will receive confirmation that your JET 3270
problem is in our support queue, problem status updates,
and a fix when ready.
Configuring the LU resource for host
print
Here are instructions on how to configure the LU resource name.
- Start JET 3270 by loading the Shortcut.htm file distributed with the
release.
- Click Cancel on the Connect dialog box.
- Select Preferences -> Edit Preference Sets...
- On Edit Preference Sets window, Select "Untitled" preference set, then
Change...
- On Change Untitled Preference Set window, select the Connection tab.

host. You may need to talk with your IBM system administrator to find
out the name of an LU pool or LU name that you can use that is
associated with one of the host printers.
- Click "OK".
- Select Connection -> Connect..., and enter host name and port number.
