The Java Applet and Java Client AP
Problem Resolution
I can't connect to the switch. 1. The latest Java version must be installed on your
Local Client computer.
2. Check if you need to specify the Program port along
with the IP address. See Java Client AP Login,
page 42, for details.
3. Close Java reopen it, and try again.
I have installed the latest
Java JRE, but I am having
performance and stability
problems.
There may be issues with the latest version because it is
so new. Try using a Java version that is one or two
versions earlier than the latest one.
After upgrading the
firmware, after logging in
with the Java Applet Viewer
or the Java Client AP, the
switch appears to still be
using the old firmware
version.
Log out. Delete your Java temporary internet files as
follows:
1. Open Control Panel
→ Java.
2. In the Temporary Internet Files section, click
Settings.
3. In the Disk Space section, click Delete Files.
4. In the dialog box that comes up, click OK.
The national language
characters that I input do
not appear.
Change the keyboard language of your computer to
English-UK.
Use the switch On-Screen Keyboard and set the on-
screen keyboard to the same language that the other
system is using. (See The On-Screen Keyboard,
page 73.)
Java performance
deteriorates.
Exit the program and start again.
Pressing the Windows
Menu key has no effect.
Java doesn't support the Windows Menu key.
