To access this tab, select Tools > Plugins to open the Plugins Manager, then select the Settings tab. This tab displays the default update center for the SDK - the Java ME SDK Toolbar Update Center.
By default the Plugins Manager checks for updates once per week, as determined by the Check Interval selection. You can select a different interval from the dropdown list.
Click the Add button to Add an update center URL.
Click the Proxy Settings button to edit the proxy settings to allow access to update centers.
Force install into shared directories determines whether the plugin is installed for an individual user or all users in the multiple user environment. If the box is unchecked (default) the plugin is only installed for the user. If it is checked, the installation is global, as described in Installing a Plugin Globally.
