Troubleshooting Security

If you want to monitor security access, you can set the java.security.debug System property. To see a list of all debugging options, use the help setting:

java -Djava.security.debug=help

Note:

Separate multiple options with a comma.
For more information, on debugging utilities please visit JSSE Reference Guide.

The following table lists java.security.debug options and links to further information about each option:

Option	Description	Further Information
`all`	Turn on all debugging	None
`access`	Print all results from the `AccessController.checkPermission` method. You can use the following options with the `access` option: `stack`: Include stack trace `domain`: Dump all domains in context `failure`: Before throwing exception, dump stack and domain that do not have permission You can use the following options with the `stack` and `domain` options: `permission=<classname>`: Only dump output if specified permission is being checked `codebase=<URL>`: Only dump output if specified codebase is being checked	Permissions
`certpath`	Turns on debugging for the PKIX `CertPathValidator` and `CertPathBuilder` implementations. You can use the `ocsp` option with the certpath option for OCSP protocol tracing. A hexadecimal dump of the OCSP request and response bytes is displayed.	Java PKI Programmer's Guide
