Reproduced struts Chinese solution Published: 2002-9-13 9:10 am 1. ApplicationResources.properties support the establishment of a Chinese ApplicationResources_ISO.properties file, the application with the message written in, and then execute this command in dos, native2ascii -encoding gb2312 ApplicationResources_ISO.properties ApplicationResources.properties this will convert the ISO code into ApplicationResources GB2312 encoding format, and while the tool is saved to ApplicationResources.properties.native2ascii jdk carrying a stuff, so if the path are located You can run directly, you can find him under $ java_home $ / bin. The conversion is similar to this like ISO format: tj.type = commodity vehicle type GB2312 format: tj.type = / u5546 / u54c1 / u8f66 / u7c7b / u578b then set this resource file in Struts-Config.xml
2. Make database operations support Chinese. Database Operation Support Chinese has always made me more headache, but I would like to recommend www.chinaxp.org for the good understanding, this website is developed with the Struts framework, and open source, download the source code, find it. Ok, read some source code, did not find any special character set conversion, very wonderful, accidentally saw that the upstairs message knows that the servlet can set the character conversion. Chinaxp.org is doing this. Plus

}
} // EOC After adding this, you can receive GB2312 encoded data directly from the Form, and naturally GB2312 is naturally GB2312. But this seems to need a container of servlet 2.2 or more.
Comprehensive way, I solved the Chinese problem in Struts, and I haven't found new problems yet.
