kandi X-RAY | zengine Summary
There are many JavaScript 3D libraries out there, such as [THREE.js] but I wanted to challenge myself to write the neatest, most simple code that accomplishes rendering objects in 3D to a 2D screen. Ignoring comments, all the code that was necessary to build this to its current functionality is under 100 lines!.

QUESTION
I followed this tutorial to implement java sandboxing for plugin code. Plugin code gets ran with the following permission:
...ANSWER
Answered 2018-Jul-04 at 13:52You run command python
(unqualified), so start()
doesn't know where the file is, and therefore check if you're allowed execute
access to <>
. Since you're not, it's rejected.
If you specify full (absolute) path to python
and grant access to the python
file, it'll work.
See javadoc of SecurityManager.checkExec(String cmd)
for description of permission check:
Throws a
SecurityException
if the calling thread is not allowed to create a subprocess.This method is invoked for the current security manager by the
exec
methods of classRuntime
.This method calls
checkPermission
with theFilePermission(cmd,"execute")
permission if cmd is an absolute path, otherwise it callscheckPermission
withFilePermission("<>","execute")
.
