In Arch Linux Wiki page, it mentioned that OpenJDK is nearly perfect which we need not to install Oracle proprietary Java. But sadly to know, there are some Java applet which needs Java Runtime Environment version 6 instead of 7. That means, neither OpenJDK nor Oracle proprietary Java 7 works.

Therefore, I need to replace the jdk7-openjdk, jre7-openjdk, and jre7-openjdk-headless with AUR jre6 and jdk6. Besides that, icedtea-web-java7 is also no needed.

When downloading the files contain Chinese or Japanese characters using JDownloader in Linux (for my case, Arch Linux), I found that all the Chinese or Japanese characters are shown with boxes. There are a lot of suggested solutions I found from Internet, especially adding !font=Dialog to the language file. I also tried to edit the fontconfig.properties file, adding path to JAVA_FONTS, etc. But all the solutions do not work.

So, my solution is, just change the user interface style to non-Synthetica style, eg, Substance or Light. Both types of style work well, allow me to see the file names with correct characters. Problem solved.

Finally, I success to run Mono with GTK# pre-compiled by Linux in Windows.

Firstly, make sure Windows is installed with

• Mono for Windows, GTK#, and XSP
• GTK# for .NET

With the above installation, one can run the Mono application normally. I failed previously because I didn’t install GTK# for .NET.

However, when I run the application, there is a console window, which is annoyance. Thus, build the Mono application with

Password Cipher which I have written was in console mode. To make it more usable, I port it into Java, then build a simple user interface. For more detail, please read here.
