- For a description of the terminology
- used in this document, see the chapter in the Optima++ documentation
- entitled "Writing Internet Applications".
-
- A Server system on the World Wide Web can send the contents of files to a User
- system, running a browser.
-
- Using the Starbuck Java target template "Java WWW Server Application", you
- can write a Server application that can dynamically create the information
- that will be displayed by the User system.
-
- Your application can use the PrintStream class to output HTML to the
- User system, and access common Web Server variables and form contents.
- In addition, you can use the power of Java to open sockets on another system,
- use JDBC to access a server database, dynamically load other Java classes,
- or load/execute native methods from a DLL.
-
- Persistent Classes
-
- If you are using either the Netscape or Microsoft Servers with the
- NSAPI or ISAPI interfaces, your application can be persistent. It will
- be loaded into memory once, and can be re-executed repeatedly without
- delay. You can use the Session object to maintain information for a user
- connection (across multiple requests). Any static class objects in your
- application will be available for all requests.
-
- Supported Servers:
-
- o Microsoft Internet Information Server (IIS) using the ISAPI interface,
- with persistent Java execution.
-
- o Netscape Commerce and Fasttrack servers, using the NSAPI interface,
- with persistent Java execution.
-
- o O'Reilly WebSite using the ISAPI emulation (but see restrictions below).
-
- o any Web server that supports Common Gateway Interface (CGI) programs.
-
- Restrictions:
-
- o your server must be running on a Windows 95 or Windows NT system.
-
- o if you are using the Common Gateway Interface (CGI), session information is
- not available -- your Java application will be reloaded for each request.
-
- o if you are using the Microsoft ISAPI interface in the O'Reilly WebSite server,
- your Java application will be reloaded for each request. Like CGI, session information
- will be unavailable.
-
- o the Microsoft Java Virtual Machine (VM) is used to run the application. You
- must have installed the Java VM on the server machine.
- For Netscape servers, the embedded Netscape Java VM is *not* used.
-
- Bugs:
-
- o this beta has a bug whereby garbage collection in the Microsoft Java VM will cause
- the application to fail. We anticipate a fix shortly.
