I'd like to use JFreeChart to create charts from code running under a security manager. This fails with the error message
java.lang.InternalError: Can't connect to window server - not enough permissions.
If I change my policy file to give the code unrestricted permissions, it works fine, so the error must be due to some permission missing in my policy. But which one? I tried various AWT-related permissions but nothing seems to work. Is there a way to find out which permissions are missing?
When you start the app , add the following to the jvm arguments - it produces a huge amount of output, but it will point you in the right direction when there are permissions failures.
-Djava.security.debug=access,failure

I am trying to run Android application on Paired Device via Wifi and it fail to run with following error:
I guess it is due to the audit warning that it cannot read respective file in /mnt/vendor folder, but Android is not my main technology field so I am at wits end what the solution might be.
It also look like the application is not trusted, but it have all the permissions as I am using example application from someone else and the AndroidManifest.xml permissions are the same.
Thanks a lot in advance!
I am facing 1 issue and could not solve it yet.
ERROR : "java.lang.RuntimeException: java.lang.SecurityException: NetworkStats: Neither user 10053 nor current process has android.permission.READ_NETWORK_USAGE_HISTORY".
I am implementing this in API 23 which is having a runtime security implementation for permission, I hope you understand what I am trying to say. I was able to add android.permission.READ_NETWORK_USAGE_HISTORY in Manifest but I am not able to add the same permission in Java file because its giving the compilation error. Could you please help ?
Below is the Manifest.xml code :- (Working fine with a waring)
Below is the Java code :- (Compilation Failed)
It allows only for System Apps not for Normal Applications. So we can't get the access for read Network Usage History.
you want access network information you should use this permission
"android.permission.ACCESS_NETWORK_STATE"
Allows applications to access information about networks.

I am trying to use the grinder load testing tool to reproduce the navigation recorded on a .har file using chrome dev tools.
I have generated this test script using har2grinder.
The script looks faily simple, just a bunch of get/post invocations and their headers.
I launch the grinder console:
java -classpath lib/grinder.jar net.grinder.Console
And then the agent processes, using this properties file:
java -classpath lib/grinder.jar net.grinder.Grinder grinder.properties
Then I start the whole thing from the console and all I can get is this output, showing 1000 errors on each of the 2 pages visited:
The web server (tomcat) log doesn't show any hits, and I don't see any grinder logs with any further details. How can I trace the problem?
Cant access the properties file :(
You need to look into the properties first and get the logs working ,
Please check grinder.logDirectory value , the logs will contain information .
Secondly check whether grinder.useConsole is set or not and the value of grinder.consolePort grinder.consoleHost have been edited to something other than default .Usually this change is not required.
Also set grinder.processes ,grinder.thread and grinder.run to 1 so that there is only one process with one thread and executes once will be easier to debug .
Next if you are NOT running against localhost then probably check that its not getting blocked across firewall since Grinder is really fast and can send many request in a small time .However these type of errors will get recorded in grinder logs and are very self explanatory.
Hello my problem is that when I try to change weather or not the GPS setting is enabled I get the following error 10-20 05:44:31.890: E/AndroidRuntime(889): java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS while in my manifest file I do have the permission listed in the error inside my manifest file.
Manifest:
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
Any help would be appreciated
WRITE_SECURE_SETTINGS is a signatureOrSystem permission, meaning that ordinary SDK applications cannot hold it. Only apps that are related to the firmware can hold this permission.
Reading all answers for this particular issue, one way around for this is to use this code to enable the gps but it wont work, as CommonsWare pointed, the application has to be system app for getting this code to work..so one can convert the application into system app by using TitaniumBackup. THis is working perfectly fine for me now.
*Sony users will see another message "Will collect anonymous data while using gps" - to overcome this, 'Freeze' the "LEarning Client" app and everything will be fine.
I have mobile application in which I have added mobile file browsing. But when ever I try to open some directory or some file, it raises exception that application is trying to access mobile data.
So how do I overcome this error? If somebody could also tell me that how overcome security exception while install the application?
Actually this is not an error. You are using JSR-75. So permission needed for accessing file from memory card or phone memory.
This is not coding related issue. Basically this type of confirm alert asking for security purpose. Because you are using JSR-75.
In this purpose, You need to sign your application with at least any 3rd party signature like one from Verisign or Thrawte and then go to the application settings - permissions - and set permission for "Access User Data" as "Ask only Once" or "Allow Always" (these settings might not be available for your unsiged app on the device.)
If you facing this Issue on the emulator, go to preferences and MIDP tab, set the application domain to Trusted and set permission as "Allow Always". For more info, see here...
Signing sites are,
Thawte
