If an active deployment rule set is installed on the system, the link View the active Deployment Rule Set is shown before the Manage Certificates button. Click the link to view the rule set. When a rule set is available, the rules determine if a RIA is run without security prompts, run with security prompts, or blocked. For more information on deployment rules, see Deployment Rule Set. For more information on security prompts, see Security Dialogs.

An option to hide a prompt in the future is included in some security prompts that are shown when an application starts. To insure the continued security of your system, it is recommended that you periodically restore the prompts that were hidden. Seeing the prompts again provides an opportunity to review the applications and ensure that you still want them to run. To restore the prompts that were previously hidden, click Restore Security Prompts.

When asked to confirm the selection, click Restore All. The next time an application is started, the security prompt for that application is shown. Click Manage Certificates to get the Certificates dialog, which looks like this:. It handles both User- and System-Level enterprise-wide certificates of the following types:. These are certificates of Certificate Authorities CAs for secure sites; Certificate Authorities are the ones who issue the certificates for secure sites.

For user-level certificates, there are four options: Import , Export , Remove , and Details. The user can import, export, remove, and view the details of a certificate. For instance, on Microsoft Windows 7, the default location of the keystore files for user jsmith would be as follows:. For non-default locations of the certificate keystore files, specify them in the User-Level deployment.

For System-Level certificates, the only options a user has are Export and Details. Trusted, Secure Site, and Client Authentication certificate keystore files do not exist by default. Thus there are no default locations for them. The location of the keystore files for the various types of certificates can also be set in a System-Level deployment.

The System-Level deployment. It is specified in a deployment. See System-Level deployment. The following properties may be specified:.

This provides options for Java Web Start for creating shortcuts on the desktop. The options are:. The options are radio button, select only one :. A Java application or applet that is launched with Java Web Start can either be installed or cached on the client computer.

If the Java application is cached, then Java Web Start stores the entire application in its cache; the application is removed from the client computer when Java Web Start empties its cache. If the Java application is installed, then the application will have an entry in the Add or Remove Programs applet in Windows Control Panel. A Java application or applet can specify if it prefers to be cached or installed; if the Java application specifies that it prefers to be installed, then it is hinted.

By default, Java applications that are hinted are installed on the client computer. You can also specify that a Java application is installed if it creates a shortcut on the client computer's desktop.

These options are check boxes. You can select any number of available options. All options are checked by default except for those specified. The following are the various Java security options:. The Mixed code options are radio buttons. You can select only one option.

Before a signed applet or Java Web Start application is run, the certificates used to sign the JAR file can be checked to ensure that none have been revoked.

This check can be disabled, but that is not recommended.
