## Tested environments

The IBM SDK for Linux, v5.0 was tested using multiple Linux distributions, windows managers, and input methods.

The following Japanese environments were tested for the IBM SDK for Linux platforms, Java 2 Technology Edition, Version 5.0.

Table 1. Tested environments
Distribution | Desktop or window manager | Input method
--- | --- | ---
Novell Linux Desktop 9 for x86 SP1 | KDE3-3.2.1 | kinput2-v3.1 Canna-3.7p1

### SuSE Linux Enterprise Server 11 for Japanese users

Sometimes an incorrect fonts.dir is generated by the SLES11 installation process. Java uses X11 font settings in fonts.dir to access to True Type fonts. With the wrong fonts.dir, Java might not display the correct characters.

This issue applies only to Japanese TrueType fonts such as Sazanami Gothic and Sazanami Mincho.

To verify your installation, check fonts.dir after installation using the command:

    $ grep "^sazanami-.*misc-sazanami.*10646" /usr/share/fonts/truetype/fonts.dir
    sazanami-gothic.ttf -misc-sazanami gothic-medium-r-normal--0-0-0-0-p-0-iso10646-1
    sazanami-mincho.ttf -misc-sazanami mincho-medium-r-normal--0-0-0-0-p-0-iso10646-1

If your output is not similar to the example output, a root user must run the commands:

    # mkdir /tmp/fonts
    # cd /tmp/fonts
    # cp -i /usr/share/fonts/truetype/sazanami-*.ttf .
    # mkfontscale .
    # cp fonts.scale /usr/share/fonts/truetype/fonts.scale.sazanami
    # cd ~
    # /usr/sbin/fonts-config -v -d -f
    # rm -rf /tmp/fonts

Verify using the previous grep command.

Note: You should use the library `libjavaplugin_ojigtk2.so` on SLES11.

## Displaying Japanese halfwidth Katakana characters

Halfwidth Katakana characters might not be displayed correctly because of the lack of font data for those characters.

## Japanese Kana-Kanji conversion

On Japanese versions of Linux, you can use a Japanese input method such as Canna or FreeWnn.

### Input Method Editor (IME)

Known limitations and solutions for IME users.

If you use an IME on a TextArea or a TextField component with Motif AWT, the composed text is sometimes displayed in the wrong position. To avoid this problem, do not change the component position vertically after you commit a string. If you do encounter this problem, reactivate the IME; the composed text is then displayed at the correct position. The committed text is always displayed at the correct position.

If you are using kinput2 as the input method server, do not use the Close button on the window frame because kinput2 might be stopped by this operation.

If you are using IIIMF as the input method server on Red Hat Enterprise Linux 4, Java requires the IIIMF packages (iiimf-*-12.1.13.EL.2) or higher. These packages are included in Red Hat Enterprise Linux 4 Update 2 or later.

### Canna

Limitations using Canna with quoted-insert-mode.

If you switch to quoted-insert-mode by pressing Ctrl + Q, entering control characters might cause unexpected behavior. To avoid this problem, disable quoted-insert-mode by adding the following line to $HOME/.canna. If $HOME/.canna does not exist, copy default.canna to the home directory as $HOME/.canna and add the following line:

    (global-unbind-key-function 'quoted-insert)

### FreeWnn

If you are using FreeWnn, the numpad Enter key might not create a new line and a carriage return while the Input Method Editor (IME) is activated. To create a new line and carriage return, deactivate the IME.

# AMD64 and Intel EM64T architecture

With an XDM connection, the window manager and input method on the System z system is used. With an SSH X11 Forwarding connection, the window manager and input method on the PC-side OS is used.
Note: For SuSE Linux Enterprise Server 11 for Japanese users, an incorrect fonts.dir might be generated by the SLES11 installation process. Java uses X11 font settings in fonts.dir to access True Type fonts. If the fonts.dir is incorrect, Java might not display the correct characters. This problem applies only to the Japanese TrueType fonts Sazanami Gothic, and Sazanami Mincho. To check the fonts.dir after installation, enter the following command:

    $ grep "^sazanami-.*misc-sazanami.*10646" /usr/share/fonts/truetype/fonts.dir

You should see results similar to the following output:

    sazanami-gothic.ttf -misc-sazanami gothic-medium-r-normal--0-0-0-0-p-0-iso10646-1
    sazanami-mincho.ttf -misc-sazanami mincho-medium-r-normal--0-0-0-0-p-0-iso10646-1

If your results are not similar, run the following commands as a root user:

    mkdir /tmp/fonts
    cd /tmp/fonts
    cp -i /usr/share/fonts/truetype/sazanami-*.ttf .
    mkfontscale .
    cp fonts.scale /usr/share/fonts/truetype/fonts.scale.sazanami
    cd ~

For verification, use the grep command.

Note: System z systems do not have graphical displays. To use graphical Java applications on Ssytem z you must run an X-Server on another system and use XDM or SSH X11 Forwarding on System z. With an XDM connection, the window manager and input method on the System z system is used. With an SSH X11 Forwarding connection, the window manager and input method on the PC-side OS is used.
Note: For SuSE Linux Enterprise Server 11 for Japanese users, an incorrect fonts.dir might be generated by the SLES11 installation process. Java uses X11 font settings in fonts.dir to access True Type fonts. If the fonts.dir is incorrect, Java might not display the correct characters. This problem applies only to the Japanese TrueType fonts Sazanami Gothic, and Sazanami Mincho. To check the fonts.dir after installation, enter the following command:

    $ grep "^sazanami-.*misc-sazanami.*10646" /usr/share/fonts/truetype/fonts.dir

You should see results similar to the following output:

    sazanami-gothic.ttf -misc-sazanami gothic-medium-r-normal--0-0-0-0-p-0-iso10646-1
    sazanami-mincho.ttf -misc-sazanami mincho-medium-r-normal--0-0-0-0-p-0-iso10646-1

If your results are not similar, run the following commands as a root user:

    mkdir /tmp/fonts
    cd /tmp/fonts
    cp -i /usr/share/fonts/truetype/sazanami-*.ttf .
    mkfontscale .
    cp fonts.scale /usr/share/fonts/truetype/fonts.scale.sazanami
    cd ~
    /usr/sbin/fonts-config -v -d -f
    rm -rf /tmp/fonts

For verification, use the grep command.

## Displaying Japanese halfwidth Katakana characters

Halfwidth Katakana characters might not be displayed correctly because of the lack of font data for those characters.

## Japanese Kana-Kanji conversion

On Japanese versions of Linux, you can use a Japanese input method such as Canna or FreeWnn.

### Input Method Editor (IME)

Known limitations and solutions for IME users.

If you use an IME on a TextArea or a TextField component with Motif AWT, the composed text is sometimes displayed in the wrong position. To avoid this problem, do not change the component position vertically after you commit a string. If you do encounter this problem, reactivate the IME; the composed text is then displayed at the correct position. The committed text is always displayed at the correct position.

If you are using kinput2 as the input method server, do not use the Close button on the window frame because kinput2 might be stopped by this operation.

If you are using IIIMF as the input method server on Red Hat Enterprise Linux 4, Java requires the IIIMF packages (iiimf-*-12.1.13.EL.2) or higher. These packages are included in Red Hat Enterprise Linux 4 Update 2 or later.

If you are using PC-side IIIMF as the input method server, you might not be able to input any characters. If you see this situation, please contact Red Hat. See Red Hat Bugzilla number RIT77126.

If you are using IIIMF as the input method server, you might experience IIIMF failures or a failure to start. See Red Hat Bugzilla number RIT73533.

### Canna

Limitations using Canna with quoted-insert-mode.

If you switch to quoted-insert-mode by pressing Ctrl + Q, entering control characters might cause unexpected behavior. To avoid this problem, disable quoted-insert-mode by adding the following line to $HOME/.canna. If $HOME/.canna does not exist, copy default.canna to the home directory as $HOME/.canna and add the following line:

    (global-unbind-key-function 'quoted-insert)

### FreeWnn

If you are using FreeWnn, the numpad Enter key might not create a new line and a carriage return while the Input Method Editor (IME) is activated. To create a new line and carriage return, deactivate the IME.
