It is well known that the directory specified by System Properties Java.ext.dirs in JAVA is loaded by the Extclassloader loader, and if your program does not specify that system property (-djava.ext.dirs=sss/lib), the loader defaults to loading $java_ All jar files under the Home/lib/ext directory. But if you manually specify the system properties and forget to add the $java_home/lib/ext path, then Extclassloader will not load the jar file under $java_home/lib/ext, which means you will lose some functionality, For example, Java comes with the encryption and decryption algorithm implementation.

Use Java.ext.dirs System Properties! -Push cool. htm
