| 50 | Java is an object-oriented programming language developed by Sun Microsystems. The Java Depvelopers Kit (JDK), |
| 51 | which contains the basic Java class packages, is available from Sun in both source and binary forms at |
| 52 | Sun's <A HREF="http://java.sun.com/java.sun.com/JDK-1.0/index.html">JavaSoft</A> site. This document |
| 53 | assumes that you have some familiarity with the basics of compiling and running Java programs. |

| 56 | There are two kinds of applications built using Java. |

| 70 | The initial emphasis on using Java for client side applets should not obscure the fact that Java is a full |

| 72 | and now FastCGI applications. |

| 219 | To run TinyFCGI as FastCGI, you invoke the Java interpreter with the -D option, giving it the |

| 221 | configuration. The command is:<BR> |

| 232 | <BR> |
| 233 | </LI> |
| 234 | <LI> |
| 235 | Finally, you can run TinyFCGI as a straight CGI program by pointing your browser at |
| 236 | <TT>fcgi-devel-kit/examplesi/TinyFCGI.cgi.</TT> The results are exactly the same as when you ran TinyCGI. |
| 237 | Invoking a FastCGI program without an <TT>FCGI_PORT</TT> parameter tells the FastCGI interface to leave the |
| 238 | normal CGI environment in place. |
| 239 | </LI> |
| 240 | </UL> |
| 241 | <P> |
| 242 | Due to gaps in the Java interpreter's support for listening sockets, Java FastCGI applications are |
| 243 | currently limited to being started as external applications. They can't be started and managed by the Web |
| 244 | server because they are incapable of using a listening socket that the Web server creates. |
| 245 | </P> |
| 246 | <H3> |
| 247 | <A NAME="S3">3. Standard I/O and Application Libraries</A> |
| 248 | </H3> |
| 249 | <P> |
| 250 | As we have seen above, FastCGI for Java offers a redefinition of standard I/O corresponding to the the |
| 251 | <I>fcgi_stdio</I> functionality. It also offers a set of directly callable I/O methods corresponding to the |
| 252 | <I>fcgiapp</I> C library. To understand where these methods occur we need to look briefly at the FastCGI |
| 253 | redefinition of standard I/O. |
| 254 | </P> |
| 255 | <P> |
| 256 | Java defines standard I/O in the <I>java.System</I> class as follows: |
| 257 | </P> |
| 258 | <P> |
| 259 | public static InputStream in = new BufferedInputStream(new FileInputStream(FileDescriptor.in), 128);<BR> |
| 260 | public static PrintStream out = new PrintStream(new BufferedOutputStream(new |
| 261 | FileOutputStream(FileDescriptor.out), 128), true);<BR> |
| 262 | public static PrintStream err = new PrintStream(new BufferedOutputStream(new |
| 263 | FileOutputStream(FileDescriptor.err), 128), true); |
| 264 | </P> |
| 265 | <P> |
| 266 | The File Descriptors <I>in</I>, <I>out</I>, <I>err</I> are constants set to 0, 1 and 2 respectively. |
| 267 | </P> |
| 268 | <P> |
| 269 | The FastCGI interface redefines <I>java.System in, out</I>, and <I>err</I> by replacing the File streams with |
| 270 | Socket streams and inserting streams which know how to manage the FastCGI protocol between the Socket streams |
| 271 | and the Buffered streams in the above definitions. |
| 272 | </P> |
| 273 | <P> |
| 274 | For those cases where the FCGI application needs to bypass the standard I/O streams, it can directly access |
| 275 | the methods of the FCGI input and output streams which roughly correspond to the functions in the C |
| 276 | <I>fcgiapp</I> library. These streams can be accessed via the <I>request</I> class variable in FCGIInterface. |
| 277 | Each Request object has instance variables that refer to an FCGIInputStream, and to two FCGIOutputStreams |
| 278 | associated with that request. |
| 279 | </P> |
| 280 | <H3> |
| 281 | <A NAME="S4">4. Environment Variables</A> |
| 282 | </H3> |
| 283 | <P> |
| 284 | Java does not use the C <I>environ</I> list. Nor is there a <I>getenv</I> command that reads system |
| 285 | environment variables. This is intentional for reasons of portability and security. Java has an internal |
| 286 | dictionary of properties which belongs to the System class. These System properties are <I>name/value</I> |
| 287 | associations that constitute the Java environment. When a Java application starts up, it reads in a file with |
| 288 | default properties. As we have seen, additional System properties may be inserted by using the -D <I>Java</I> |
| 289 | command argument. |
| 290 | </P> |
| 291 | <P> |
| 292 | For CGI, where the Java application is invoked from a .cgi script that, in turn, invokes the Java interpreter, |
| 293 | this script could read the environment and pass the variables to the Java application either by writing a file |
| 294 | or by creating -D options on the fly. Both of these methods are somewhat awkward. |
| 295 | </P> |
| 296 | <P> |
| 297 | For FastCGI Java applications, the environment variables are obtained from the FastCGI web server via |
| 298 | <TT>FCGI_PARAMS</TT> records that are sent to the application at the start of each request. The FastCGI |
| 299 | interface stores the original startup properties, combines these with the properties obtained from the server, |
| 300 | and puts the new set of properties in the System properties dictionary. The only parameter that has to be |
| 301 | specifically added at startup time is the FCGI_PORT parameter for the Socket creation. In the future, we |
| 302 | expect that even this parameter won't be needed, since its use is due to an acknowledged rigidity in the |
| 303 | JDK's implementation of sockets. |

| 309 | </H3> |
| 310 | <P> |
| 311 | The next two examples illustrate the points made in the last two sections. EchoFCGI and Echo2FCGI both echo |
| 312 | user input and display the application's environment variables. EchoFCGI reads the user input from |
| 313 | System.in, while Echo2FCGI reads the user input directly from the intermediate FastCGI input stream. |

| 446 | The Java FastCGI classes are included in both source and byte code format in <I>fcgi-devel-kit/java/src</I> |
| 447 | and :<I>fcgi-devel-kit/java/classes</I> respectively. The following is a brief description of these classes: |

| 451 | <DL> |
| 452 | <DT CLASS="c4"> |
| 453 | FCGIInterface |
| 454 | </DT> |
| 455 | <DD> |
| 456 | This class contains the FCGIaccept method called by the FastCGI user application. This method sets up the |
| 457 | appropriate FastCGI environment for communication with the web server and manages FastCGI requests.<BR> |
| 458 | </DD> |
| 459 | <DT CLASS="c4"> |
| 460 | FCGIInputStream |
| 461 | </DT> |
| 462 | <DD> |
| 463 | This input stream manages FastCGI internal buffers to ensure that the user gets all of the FastCGI messages |
| 464 | associated with a request. It uses FCGIMessage objects to interpret these incoming messages.<BR> |
| 465 | </DD> |
| 466 | <DT CLASS="c4"> |
| 467 | FCGIOutputStream |
| 468 | </DT> |
| 469 | <DD> |
| 470 | This output stream manages FastCGI internal buffers to send user data back to the web server and to notify |
| 471 | the server of various FCGI protocol conditions. It uses FCGIMessage objects to format outgoing FastCGI |
| 472 | messages.<BR> |
| 473 | </DD> |
| 474 | <DT CLASS="c4"> |
| 475 | FCGIMessage |
| 476 | </DT> |
| 477 | <DD> |
| 478 | This is the only class that understands the actual structure of the FastCGI messages. It interprets |
| 479 | incoming FastCGI records and constructs outgoing ones..<BR> |
| 480 | </DD> |
| 481 | <DT CLASS="c4"> |
| 482 | FCGIRequest |
| 483 | </DT> |
| 484 | <DD> |
| 485 | This class currently contains data fields used by FastCGI to manage user requests. In a multi-threaded |
| 486 | version of FastCGI, the role of this class will be expanded.<BR> |
| 487 | </DD> |
| 488 | <DT CLASS="c4"> |
| 489 | FCGIGlobalDefs |
| 490 | </DT> |
| 491 | <DD> |
| 492 | This class contains definitions of FastCGI constants. |
