In eclipse warning: Default charset GBK not supported, the ultimate solution to the problem of using ISO-8859-1 instead

This problem is caused by incorrect Character Set settings in installed jres. Edit the preceding JRE and you can see that the above libs does not contain charset. jar, which is related to the character set. So 1. Add this lib (JRE/lib/charset. Jar ). 2. Use JDK as instanlled jres. Click Add and select your JDK in JRE home direcotory. By default, charset. jar is available in libs. When Tomcat is ready, this character set is not supported. The solution is the same as above. Check JRE and add charset. jar, or use JDK for JRE. In addition, sysdeo stated in earlier versions that JDK is preferred for JRE.
