问题
I am trying to access client's temp directory through my applet on my web project.
When I run the applet by itself, it gets the tempdir with no problem.
When I try to get it on my project using javascript and calling the applet method, I am having accessControlException on my javascript console. Also I am getting the same exception when I try to read a file under the temp directory.
This is what I see exactly:
java.security.accesscontrolexception access denied (java.util.propertypermission java.io.tmpdir read)
java.security.accesscontrolexception access denied (java.io.filepermission read)
How to solve java.security.AccessControlException?
回答1:
Simplest solution is just to sign the applet.
