If the emulator client applet loads but the emulator session does not connect, try the following:
ping 255.123.123.3.
myclient, type ping
myclient. nslookup w.x.y.z,
where w.x.y.z is the dotted decimal address of the host.
If the client is given a numeric address, it contacts the local DNS
to get the host name. Sometimes the DNS is not set up properly for
this reverse look-up. If the DNS is not setup properly, add the host
name and address to the HOSTS file on the client.

You do not need to check this port if you are using the HTML-based configuration model, since users do not access the Z and I Emulator for Web Service Manager. |
If you are using an old HTML file from a previous release, the Alternate Terminal interface may not come up or a Null Pointer exception message may be displayed when starting a session. If this happens, you may need to edit the HTML file, and replace any occurences of scbase.jar or scbase.cab and scfull.jar or scfull.cab with sccbase.jar or sccbase.cab.
If you are using file transfer on a 5250 emulator session or loading the Database On-Demand applet and having host connection problems, check to see if you have a classes.zip entry in your CLASSPATH. If so, remove it but be aware that other programs may require this classpath entry.
The JVM in Internet Explorer handles key events differently according to its level. Remapped Alt-key combination key events are sometimes sent to the menu even after the action for the remapped key is taken. The result is that focus is put onto the menu and remains there. To regain focus, click on the active screen.
To avoid this, try using JVM levels 3167 and later.
If the FTP client fails to connect to the OS/2 FTP server when using Japanese Windows and the Netscape browser, try upgrading to a newer JRE.
On AIX and Linux, depending on the keyboard assignments for the machine and the level of Java installed on the machine, the Meta modifier might be processed with the Alt key. Thus, if you press the Alt key on these systems, you receive Meta-Alt key events. This causes problems if your Z and I Emulator for Web session is defined on Windows, a key remap assignment is done using the Alt key, and you start the session on a Linux or AIX client.
For example, the administrator defines a session using the Deployment Wizard on Windows. In this session, the administrator maps the Reset key function to the Alt-R key combination. If a user starts the Z and I Emulator for Web client on a Linux or AIX machine that processes Meta-Alt for the Alt key, they will not be able to process the Reset key function correctly. Every time that they enter the Alt-R key combination, Z and I Emulator for Web receives a Meta-Alt-R key event, which will not process the Reset function.
To fix this, the administrator of the AIX or Linux machine must use the
xmodmap command to change the keyboard assignments so that
Alt is processed without the Meta modifier. Note that the xmodmap
command affects the current X window session, so logging out restores the
key assignments to their original values.
A specific example for AIX follows:
The 1.1.5 JDK shipped under Netscape processes Meta-Alt for the left Alt key if the keysym for the right Alt Key is not assigned to mod1.
When using a non en_US.8859-1 keyboard, the Xserver may have the right Alt key, Alt_R, mapped to Mode_switch (or a key besides Alt_R). Additionally, mod1 may have the left Alt key, Alt_L, solely assigned. When mod1 only has Alt_L assigned, and this key is pressed, Meta+Alt is generated. To avoid the Meta modifier from being added to the key event, the Alt_R key must be added to mod1. To accomplish this, do the following (written in pseudocode):
xmodmap if ((mod1 = Alt_L) and (mod2 = Mode_switch, Mode_switch)) xmodmap -pke if (keycode 70 = Mode_switch) xmodmap -e "add mod1=Mode_switch"
When displaying a 3270 MOD2 (24x80) session using IBM3270 font on the Matrox Parhelia display adapter with resolution set to 2560 x 1024 pixels, characters may not display as expected and will appear unrecognizable.
You can avoid this by doing either of the following:
This problem occurs under Red Hat Linux and Netscape 6 (or later) with the IBM Java runtime environment (JRE) or the IBM JDK for Linux, Service Release 8 and below. When an empty pull-down menu or choice list is clicked (that is, when the leftmost object on the Macro Manager Toolbar has no macros present to choose from), the browser, Z and I Emulator for Web session, and the Linux X-windowing system become unresponsive.
You can avoid this problem by not clicking the empty pull-down menu, or clicking the pull-down menu only when there is at least one item to select. However, if the Linux X-window system becomes unresponsive after clicking the empty pull-down menu, restarting the X-window system returns control back to normal (without having to reboot the entire machine).
Try upgrading to the IBM Linux JDK, Service Release 9 or above. You can download this from IBM DeveloperWorks at http://www-106.ibm.com/developerworks/java/jdk/index.html. New users need to register before downloading it.
DBCS characters may become square boxes when using Windows or Red Hat Version 8.0 client operating systems. To display or print these characters correctly, try installing the Sun 1.4 Java plug-in, the IBM 1.3.1 Java plug-in, or later versions of these plug-ins.
If you are using Netscape 4.x on a Chinese-Traditional (Taiwan) Windows platform, URLs that are displayed on 3270 and 5250 session screens may be truncated and overlap with text on the same row. Try upgrading to Netcape Version 6 or later.
With On-The-Spot Conversion enabled, Z and I Emulator for Web should display the Input Method Editor (IME) composition characters in the active input position. However, when running Simplified Chinese Windows ME platforms, it displays composition characters in a separate composition window. Try upgrading the IBM JRE.
When using certain combinations of JREs and browsers, you may not be able to paste text into Z and I Emulator for Web input fields, such as those in the Macro Editor. Try upgrading the JRE to a later version.
The Unix version of Netscape is built on the Motif toolkit, which binds the F10 key to a command that activates the menu bar by default. As a result, the terminal emulation screen of Z and I Emulator for Web running on Unix versions of Netscape cannot handle the F10 keystroke.
There are two workarounds:
While using Netscape 4.x, transferring large UNICODE UTF-8 files to a host may cause the emulation session to hang. Try upgrading to Netscape Version 6 or later.
If the Database On-Demand and the 5250 File Transfer functions of Z and I Emulator for Web are not able to connect to a V5R1 iSeries host that has long password support enabled in a Netscape 4.x browser, try upgrading your browser.
On Japanese Windows XP platforms with Service Pack 1 (SP1), the IME status bar may display the incorrect input character mode, even when IME Auto Start works correctly. Try upgrading to the latest SUN JRE.
If Simplified Chinese characters do not display correctly, your Java plug-in may not support the correct font properties file (font.properties.zh). Try installing a different Java 2 plug-in.
There are two types of Won symbols in Unicode. One is \u20a9, which is a half-width SBCS Won symbol, and the other is \uffe6, which is a full-width DBCS Won symbol.
In Z and I Emulator for Web, the half-width Won symbol \u20a9 is shown as a full-width Won symbol in Traditional Chinese sessions (Code Page 937, 1371). In this case, the right side of this character is covered by the next character. This is caused by a limitation in the Ming Liu font, which is the default Monospaced font of the JRE in Traditional Chinese Windows platforms. The full-width Won sign \uffe6 displays correctly using the Ming Liu font.
To display both fonts correctly, configure the client workstation to use the IBM WorldType Monotype Sans Duospace WT font. Refer to the following URL to learn more about using IBM World Type fonts on your system:
http://<server_name>/ZIEWeb/<locale_name>/help/os400unicode.htmlwhere
<server_name> is the Z and I Emulator for Web server
name, and <locale_name> is the locale in which you
are running the Z and I Emulator for Web client, such as en or zh_TW.
When using Z and I Emulator for Web with Java 1.4.0, you may lose focus when making a selection in a choice box, and you will not be able to type in text fields. To regain focus, you may either click off of Z and I Emulator for Web into another application, your desktop, or another location, and click back, or you can minimize and then maximize the Z and I Emulator for Web panel. Try using Java Version 1.4.1.
The ATTN key value might not be recognized by some applications. If not, you can use the ATTN key parameter to specify the byte stream sent to the server when the ATTN key is pressed.
The syntax for the ATTN key parameter is:
<PARAM Name=attnKeyOverride VALUE=dddd>
When a session is connected in basic TN3270 mode, Z and I Emulator for Web sends
the following commands to the telnet server when the ATTN key is pressed:
PA1, IAC, EOR, IAC, BREAK (in hexadecimal form: 6CFFEFFFF3)
PA1 is the SNA AID key value for the PA1 key. This ATTN key value is the same default value used by Z and I Emulator for Windows.
