WebMacro is a 100% Java open-source template language that enables programmers and designers to work together while promoting the ModelViewController pattern.
WebMacro is a viable (and proven!) alternative to JavaServerPages, PHP, and ASP. Its the fundamental page technology behind several major websites such as AltaVista.
WebMacro separates concerns about program code from concerns about the way a page looks:
- HTML should not clutter up program code
- program code should not clutter up HTML
- you should OwnYourOwnWork
- no-one should have to work through somebody else

Servlet::ServletOutputStream is a servlet output stream interface.

SYNOPSIS

$stream->print($string);

$stream->println();
$stream->println($string);

$stream->write($string);
$stream->write($string, $length);
$stream->write($string, $length, $offset);

$stream->flush();

$stream->close();

Provides an output stream for writing binary data to a servlet response.
An output stream object is normally retrieved via "getOutputStream" in Servlet::ServletResponse.

NOTE: While this is an abstract class in the Java API, the Perl API provides it as an interface. The main difference is that the Perl version has no constructor. Also, it merges the methods declared in java.io.OutputStream and javax.servlet.ServletOutputStream into a single interface.

METHODS

close()

Closes the stream and releases any system resources associated with the stream.

Throws:

Servlet::Util::IOException

if an output exception occurred

flush()

Flushes this input stream and forces any buffered output bytes to be written out.

Throws:

Servlet::Util::IOException

if an output exception occurred

print($value)

Writes a scalar value to the client, with no carriage return-line feed (CRLF) character at the end.

Parameters:

$value

the value to send to the client

Throws:

Servlet::Util::IOException

if an output exception occurred

println([$value])

Writes a scalar value to the client, if specified, followed by a carriage return-line feed (CRLF) character.

Parameters:

$value

the (optional) value to send to the client

Throws:

Servlet::Util::IOException

if an output exception occurred

write($value)

write($value, $length)

write($value, $length, $offset)

Writes the scalar $value to the stream.

If no arguments are specified, functions exactly equivalently to print().

If $length is specified, writes that many bytes from $value. If $offset is specified, starts writing that many bytes from the beginning of $value. $offset and $length must not be negative, and $length must not be greater than the amount of data in $value starting from $offset.

Blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Parameters:

$value

a scalar value to be written

$length

the maximum number of bytes to write

$offset

the location in $value where data is read from

Throws:

Servlet::Util::IOException

if an input exception occurs

Servlet::Util::IndexOutOfBoundsException

if $buffer is specified as undef

MKSearch provides a Web metadata spider and search engine.

MKSearch is a metadata search engine that indexes structured metadata in Web documents instead of free text in the document body.

The data acquisition system conforms to the Dublin Core metadata in HTML recommendations, and supports other application profiles, such as the UK e-Government Metadata Standard.

It also indexes native RDF formats, including RSS 1.0. The system has five major components: a Web crawler, an HTML document validator and formatter, a set of custom indexers, an RDF storage and query system, and a public query interface, provided through a standard servlet container.

System composition

The MKSearch system is composed of several other free software components. Further details are provided in the MKSearch development plans.

JSpider
JSpider is a Java Web crawler engine that has pluggable interfaces that can be used to add custom processing and content handling. MKSearch uses custom SAX-based content handlers for extracting metadata from Web documents.

Sesame
Sesame is a set of RDF processing and storage APIs and applications that includes RDF data query facilities. MKSearch uses Sesame to store indexed metadata in RDF format and to search the repository via the public query interface.

JTidy
JTidy is a utility for correcting common HTML markup errors and is used to convert HTML documents to XHTML so they can be processed using SAX.

Apache JServ project is a 100% pure Java servlet engine designed to implement the Sun Java Servlet API 2.0 specifications and add Java Servlet capabilities to the Apache HTTP Server.

mod_jserv is a Java servlet interface.

Installation:

Installation instructions for UNIX systems are included in the INSTALL file or in the installation section of the documentation.

C++ Server Pages is a partial Java server pages and servlet implementation in C++. C++ Server Pages is written as Apache 2.0 modules, with the focus on performance.

Atomsphere is a Java library for creating and modifying Atom 1.0 compliant feed documents. Atomsphere is also bundled with a servlet-based Web interface for front-end manipulation of atom feeds.
