Question

I am trying to run a desktop application which is developed in java rmi. While I am trying to execute this application in eclipse, I am getting following error. Please any one help me thanks in advance.

Exception in thread "main" java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write)
    at java.security.AccessControlContext.checkPermission(Unknown Source)
    at java.security.AccessController.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPropertiesAccess(Unknown Source)
    at java.lang.System.getProperties(Unknown Source)
    at .HeadOfficeManager.Manager.main(Manager.java:103)

Here is the code.

public static void main(String args[])
{
    Manager frame = new Manager();
    frame.setVisible(true);
    // frame.show(); old 1.4

    // Create and install a security manager
    if (System.getSecurityManager()== null)
    {
        System.setSecurityManager(new RMISecurityManager());
    }
    try
    {
        Properties prop = System.getProperties();
        String httpPath = prop.getProperty("HTTPPath");
        new ClassFileServer(80, httpPath);
    }
    catch (IOException e)
    {}

    try
    {
        java.rmi.registry.LocateRegistry.createRegistry(1099);
        System.out.println("RMI registry ready.");
    }
    catch (Exception e)
    {
        System.out.println("Exception starting RMI registry:");
        e.printStackTrace();
    }
    try
    {
        RMIHandler = new ManagerRMIHandler();

        // Bind the remote object's stub in the registry
        Registry registry = LocateRegistry.getRegistry();
        registry.rebind("HeadOfficeManager", RMIHandler);

        System.err.println("Server ready");
    }
    catch (Exception e)
    {
        System.err.println("Server exception: " + e.toString());
        e.printStackTrace();
    }

Answer 1

1. Right click on application in eclipse and click on run configurations.
2. Add virtual machine arguments as -Djava.security.policy =java.policy.applet.
3. Create a file, name it as java.policy.applet.

4. Add below lines in that file.

   grant  
   {  
       permission java.security.AllPermission;  
   };
   

5. Save it and run the application.

This will give all security permissions to your Java application.
