Problem:
How do I enable the Java Console on MS Internet Explorer V. 4.0 (IE4)?
Solution:
Do the following:
1. Open the IE4 browser
2. Select View, Internet Options
3. Select the “Advanced” tab
4. Scroll down to the “Java VM” section and select ALL the options
5. Click OK
6. RE-open the IE4 browser
7. Select View, Java Console
The Java Console will log all Java events associated with the open browser. The information will remain in
the Java Console until the browser is closed. This means that the Java Console window may be closed and
reopened within a browser session without losing any information.

1. Install the Java Plug-in
2. Select Programs, Java Plug-in Control Panel from the Start menu

If a TNG browser was previously opened, then closed, the Web Browser needs to be closed completely
before starting a new TNG browser session.
Problem:
What ports need to be opened for the TNG browser to work?
Solution:
5635 and 5636
Problem:
I’m having trouble accessing an HTTP file in the TNG directory.
Solution:
Verify that the HTTP aliases are properly set. To do so:
1. Select Programs, Microsoft Internet Server (common) from the Start button
2. Select Internet Service Manager
3. Verify that the server shows the “www” services is “running.”
4. Highlight and double-click on the server with WWW
5. Click on the Directories tab
6.
Verify that the following “aliases” are set (examples below assume TNG is installed on drive
C:)
 C:\TNG\browser /tngfw
 C:\TNG\browser /tng
 C:\TNG\browser\scripts /tngfw/scripts
 C:\TNG\browser\scripts /tng/scripts
Problem:
A yellow banner “Warning: Applet Window” appears at the bottom of the windows.
Solution:
This occurs because a certificate of authority is not available for use with Sun’s JVMs (Java Plug-in,
HotJava or appletviewer).
If you are using JVM release 1.1.x, do the following:
1. download the file :%CAIGLBL0000\browser\classes\CATNG.x509 from the web interface
server
2. import the certificate key into the identitydb.obj file by using the following commands:
javakey –c CATNG true
javakey –ic CATNG CATNG.x509
If you are using JVM release 1.2.x, do the following:
1. download the file: %CAIGLBL0000\browser\classes\CATNG.x509 from the web interface
server
2. import the certificate into the identitydb.obj file by using the following command:
keytool –import –alias CATNG –file CATNG.x509
