EJS 4.3 support utf-32 characters and extension for the default source become "ejs" instead of "xml".

Before this evening: The upload jar file option at this server only support jar files generated with "xml" type source.
I have modified the code, so it is also support jar file generated with "ejs" type source now ( at least it works fine when I tested it).

You can try it again and it should work fine now.
