Access components provide front-end access to system services, often from Internet locations outside an enterprise firewall. The following Java ES access components are described in this section:
Sun Java System Communications Express (Communications Express) provides an integrated web-based communications and collaboration client that provides end users with a web interface to calendar, email, and address book services. Communications Express consists of three client modules: Calendar, Address Book, and Mail. Configurable to provide access to either Messaging Server or Calendar Server or both, Communications Express works with either Sun Java System LDAP Schema, Version 1 (Schema 1) or Schema 2.
The Java ES installer provides Communications Express as a single installable component.
Sun Java System Web Proxy Server (Web Proxy Server) provides caching, filtering, and distribution of web content. Web Proxy Server is often used inside enterprise firewalls to reduce the number of requests to remote content servers and outside firewalls to provide a secure gateway for incoming internet requests.
The Java ES installer provides the Web Proxy Server as a single installable component.
Sun Java System Connector for Microsoft Outlook enables Outlook to be used as a desktop client with Sun Java Enterprise System. The connector is an Outlook plug-in that must be installed on the user desktop.
Connector for Microsoft Outlook queries Messaging Server for folder hierarchies and e-mail messages, then converts the information into Messaging API (MAPI) properties that Outlook can display. Similarly, Connector uses WCAP to query Calendar Server for events and tasks which are then converted into MAPI properties. With this model, Sun Java System Connector for Microsoft Outlook builds an end-user Outlook view from two separate information sources: mail from Messaging Server and calendar information from Calendar Server.
Sun Java System Connector for Microsoft Outlook is provided on the accessories CD, with its own installer.
Sun Java System Directory Proxy Server (Directory Proxy Server) is an essential component of any mission-critical directory service for e-commerce solutions. Directory Proxy Server is an LDAP application layer protocol gateway that offers enhanced directory access control, schema compatibility, and high availability using application layer load balancing and failover.
The Java ES installer provides Directory Proxy Server as a single installable component.
Sun Java System Portal Server Secure Remote Access (Portal Server Secure Remote Access) extends Portal Server by offering browser-based secure remote access to Portal Server content and services from any remote browser, eliminating the need for client software. Integration with Portal Server ensures that users receive secure access to the content and services that they have permission to access.
The Java ES installer provides Portal Server Secure Remote Access as a single installable component. If needed, the following Portal Server Secure Remote Access subcomponents can be installed separately:
Portal Server Secure Remote Access Core.
Gateway. Provides an interface and security barrier to a corporate intranet that allows remote access from outside the intranet. Gateway presents content securely from internal web servers and application servers through a single interface to a remote user.
Netlet Proxy. Enables users to securely run common TCP/IP services over the Internet and other non-secure networks. Netlet allows you to run applications such as telnet, SMTP, HTTP, and fixed-port applications.
Rewriter Proxy. Provides secure access to corporate intranet web pages from outside of the intranet by transforming web links and creating rule sets for handling intranet web pages.
