Applet Security Structure

When you instantiate an applet using the JMNewAppletViewer function, you must pass a data structure that supplies security information for the applet. This data structure is defined by the JMAppletSecurity data type.

struct JMAppletSecurity { 
   UInt32 fVersion; 
   JMNetworkSecurityOptions fNetworkSecurity; 
   JMFileSystemOptions fFileSystemSecurity;
   Boolean fRestrictSystemAccess;
   Boolean fRestrictSystemDefine; 
   Boolean fRestrictApplicationAccess; 
   Boolean fRestrictApplicationDefine; 
};

Field Description

fVersion

The version of JManager. You should set this field to kJMVersion.

JMNetworkSecurityOptions

A flag indicating access privileges for applets connecting to networks. See "Applet Security Indicators" for a list of possible values for this field.

JMFileSystemOptions

A flag indicating applet access privileges to the local file system. See "Applet Security Indicators" for a list of possible values for this field.

fRestrictSystemAccess

If set to true, the applet cannot access system packages found in the mrj.security.system.access property. (The default packages in the property are com.apple.* and sun.*.)

fRestrictSystemDefine

If set to true, the applet cannot load system packages found in the mrj.security.system.define property. (The default packages in the property are com.apple.* and sun.*.)

fRestrictApplicationAccess

If set to true, the applet cannot access application packages found in the mrj.security.application.access property.

fRestrictApplicationDefine

If set to true, the applet cannot load application packages found in the mrj.security.application.define property.
