`
`MATION editorial
`
`stafl' has teamed .
`
`up with a hand-
`firl of technically
`savvy java pro-
`
`T WASDURING AN EARLY evening
`phone conversation several weeks
`ago that it hit meaSun’s java de-
`velopment language is a lot more
`than just another new toy for the
`Internet.
`
`I was talking to_]ohn Patrick, an
`IBM VP, a.k.a “Mister Internet"
`
`among lBMers.
`“What's your take on Java?’ I asked,
`expecting the obligatory “We're working
`to support it
`in our browser‘ kind of
`answer. I had just that week finished
`putting up a couple of ]ava—animated
`6‘
`hotlinks to advertisers’ Web
`
`grammers and consultants who are
`about to launch a new technical newslet-
`ter, "The_]ava Report" (available, as they A
`say, at a newsstand near you soon. Or
`you could circle 150 on the Reader Ser— I
`vice Card).
`The result is the most complete en-
`terprise-level view of this fast-paced ,
`new phenomenon available anywhere.
`We start with a high-level
`
`~
`
`overview in ‘java: Internet
`Toy or Enterprise Tool?" (p.
`28), followed by hands—on ex-
`planations ofhow to usejava J
`to
`build
`cross-platform _
`multi—tier client/server appli-
`‘
`cations (‘Business Uses for
`java,” p. 40, and ‘How java
`Makes
`Network-Centric
`
`Computing Real," p. 42).
`Then we dig deeper with
`detailed information on the
`
`pages at Plugln DATAMA-
`TION (http://www.datama—
`tion.com), you see, sojava
`and Web browsers were
`
`connected in my mind.
`His answer surprised me.
`“IBM is porting the Java

`And. for U.S. readers, we finish down
`
`in the engine room with a special 12-

`that allows software developers to engineer
`applications that can be distributed over
`the Internet using the World VVde
`Web or any of several other from
`ends currently under develop-
`merit by lSVs.
`And second, it’s a virtual oom-
`puter (technically called the java
`Virtual Machine) that will
`eventually allow all of the
`java-based applications to
`become ubiquitous—to run
`anywhere and everywhere,
`regardless of the under-

`UNIX workstation or server to an AS/400 or an IBM S/390
`
`running MVS. It can do all this across any number ofnetwork
`and Internet protocols, using You-Narne-It database gateways
`and with Whichever distributed object standards. including
`CORBA and Network OLE.
`
`Revolutionary, no doubt But even more revolutionary is
`Srm's decision to openupjava-and particularly to open up
`thejava Virtual Machine—to any and all. That means that
`any software vendors or individual developers—be they de-
`velopment tool vendors, language compiler developers,
`RDBMS vendors, middleware vendors, client/server appli-
`cation vendors or down-in-the-basement hackers—can use
`
`thejava Virtual Machine’s bytecode language to create In-
`ternet-capable, run-anywhere applications and services.
`So, just as the revolutionary new Mac hardware and OS
`combined to usher in the end—user—ii-iendly era ofdesktop—cen—
`tric cliart/server computing in the enterprise, all this newjava
`technology is now opening the way into the emerging devel-
`oper-friendly era ofnetwork—centric C/S computing both in-
`dde the enterprise and out in the market.
`'Ihe_Iava Revolution will deliver a world ofsoliware marked
`by individual empowerment. java holds out the promise of
`making the operating system as transparent as a window pane.
`Soliware, infomiation technology, and networked content will
`be judged by its quality and service,
`not by the proprietary
`(some might say “monop-
`olistic") hold ofits creator.
`
`tem analysts, C/S developers, programmers, multimedia de-
`signers, marketing professionals, educators, managers, film
`and video producers, and even hobbyists.
`Traditionally, not many of these people have worked to-
`gether elfectively. When we talk about open systems, we
`usually talk in terms of published APIs and specifications;
`in terms of availability ofsource code; or in terms ofhard—
`ware. networking. and operating systems. But no one talks
`in terms of people being open._[ava completes the cycle of
`an open system by getting all of these human resources on
`the same page. It opens up people and, in turn. opens up
`the way corporations work.
`And it's for this reason that Sun's java is gaining a place
`in the world ofenterprise computing with incredible speed.
`With this Special Issue, DATAMATION has partnered with
`the editorial team at the Java R:/:ort—a new monthly publi-
`cation from SIGS Publications in New York City-to supply
`corporate IT decision makers with a complete guide tojava
`in the enterprise.
`We start with an in-depth interview with Sun's james
`Gosling-the man who inventedjava back in 1990-then take
`a business user's look at the technology, complete with a step-
`by-step explanation ofhow you mn usejava to implemmt net-
`work-oentric client/server applications for order/entry, ac-
`counts payable, and inventory management. Then we look at
`some technical details of

`In a recent interview
`
`with Kim Polese, Sun's
`
`senior project manager
`for java at the time, we
`asked, “What
`is Sun's
`
`business model forjavai”
`She answered with one
`
`word: "Ubiquity." (Polese is
`now with a company called
`Yajsu. which was started by
`former members of Sun's
`
`team,

`
`THE ORIGINAL JAVA team worked on designing soft-
`ware for consumer electronics. They quickly found that
`languages such as C and C++ were not adequate
`because they have to be compiled for a particular corn-
`puter chip. When a new chip comes out. most software
`has to be recompiled to make full use of new features
`on the chips. Once compiled, C and C++ programs are
`
`not easily adapted to use new software libraries. The
`programs have to be recompiled from scratch when the
`library changes.
`Consumer device software has to work on new chips,
`though. because manufacturers are constrained by the
`cost of components. If the price of a computer chip
`becomes too high, they will replace it immediately with
`a newer, more cost-effective one. Even small price vari-
`ations can make a big difference when selling millions
`of devices.
`Software used in consumer electronics must also be
`
`very reliable, much more than most computer software.
`If a consumer product fails, the manufacturer usually has
`to replace the whole machine.

`
`DATAMATION: Can you define or explain Sun’s plans for or expectations
`ofjava?
`GOSLING: Let's see. There’s a of string of [java] buzzwords out there about
`building sort ofreliable, multithreaded applicafions that can rove around the net-
`work in a safe way.
`There are a lot of mechanisms injava to let you sort of transparently move be-
`havior around. And it's not something that users will see directly, and they won't be
`afi-aid that there’s some vims coming at them that's going to take over their system.
`
`DATAMATION: You said “around the network,” not the lntemet. You
`
`make it seem as ifjava is not expressly an Internet technology.
`GOSLING: No. It's a general—purpose programming language. And people have
`used it for all kinds of stuff.
`
`A lot of what’sinteresting around it was driven by what it takes to build ap-
`plications on a network, but that's not all of it. There are lots of folks who are
`perfectly happy to have something that is a cleaned-up version of C++ with
`multithreading and garbage collection.

`
`
`
`
`
`outside his office window at Sun Microsystems.
`Later. the Java development team discovered that Oak
`
`was the name of a programming language that predated
`Sun's language, so another name had to be chosen. it's
`
`surprisingly difficult to find a good name fora program
`ming language, as the team discovered after many hours
`of brainstorming.
`Finally, inspiration struck one day during a trip to the lo-
`cal coffee Shop.

`kind of seamless access for the
`
`user, what’s going on behind the
`scenes, either in terms of a core
`
`Java technology or what a devel-
`oper might have to do withjava to
`get that to work?
`GOSLING: Well, the developer basi-
`cally writes the client side and installs
`that on the server. And when the

`
`
`here in my site station in Palo Alto.I
`just clicked on a link to a Web page.
`This went to the University of Syra-
`cuse. The Web server at Symurse sends
`this thing over, and it's embedded in the
`middle of a document. And I didn't
`
`havetogetacopyofthesoftware, copy
`it over, install it on my machine, worry
`about running some virus scanner on it.
`It just happened. So the network ap-
`pears completely transparent.
`I don’t have to have authenticated
`
`these guys [the applets]. I don’t have to
`know whether or not I can trust them.
`
`client says, "Gee, I want to look at the
`petty cash page,’ the page comes over.
`The page has [a java applet] embed-
`ded in it that says ‘Gee, this rectangle
`on the page is supposed to be occupied by the petty cash
`application. Do I have a copy of it locally? Well, no, so Ibet—
`ter go back to the server and get a copy of it." It comes over.
`’Ihat’s sort of extra—that sort of transaction, bringing it
`over—and then, once it comes over, first running it through
`something called the Verifier, which checks out a whole lot
`of stuff. Then it actually gets run. And all of these steps of
`bringing the application over, verifying it, and the rest of it,
`are completely transparent.

`Move over ODBC!
`Here Comes JDBO
`
`Every third person on the net wants database access.
`They're about to get it—Java style. Next week. Java-
`Soft will release a spec for Java Database Connection
`(JDBC), an API that lets developers write Java apps
`that access databases. To support interchangeable
`DBMS drivers, the API uses a driver manager that au-
`tomatically loads the right JDBC driver to talk to a
`given database. Javasoft will bundle the JDBC driver
`manager into future releases of Java. The company
`is also going to release a software bridge from JDBC
`to Microsoft's ODBC database driver interface.
`
`According to Javasoft president Alan Baratz, the
`driver is the first of several products in what Javasoft
`calls "the Java enterprise platform." ~a platform
`Javasoft hopes will turn Java and the Web into an
`
`enterprise-class platform for applications and infor-
`mation access.
`
`The initial spec will be released on March 8 at
`http:lfjava.sun.com. Look for the final spec and soft-
`ware this summer.—-Susan Mael
`
`because the application is essentially run inside a box that sort
`of limits what it can get at. So that it's just a programming
`language inside. The stuffthat you can write in C++ you can
`write in this. And the stuff that you could write injava you
`can also write in C++.
`
`What it gets you is the ability to have these pieces ofcode
`sort ofrove around the network. Ifyou’re somebody who has
`got some kind of data in some special form, and you want to
`publish it to the world, you just put it on your Web site and
`tell people to go look at it. And you’re not limited to
`what you can do with a normal Web tool. A normal
`Web tool gives you flat pages that are text and images.
`and it's sort of like looking at a boolc
`
`DATAMATION: How doesjava change that?
`G08I.ING:]ava lets you put arbitrary dynamic stuff in
`there. I mean, a lot of people are using it as though it
`was sort of a fancy way to do [interactive] illustrations
`in books. There are lots of folks who do things like use
`java for textbooks. What gets embedded in the pages is
`like a simulator for something—like a simulator for an os-
`cilloscope rather than a photograph ofa face on the os-
`cilloscope, or a circuit simulator instead of a circuit dia-
`gram.

`DATAMATION: It seems as thouglnjeva is very operat-

`way.
`
`GOSLING: True. You don't [need to] know whether some-
`body is nmning on a Mac, a PC, or any old flavor ofUNlX.
`
`DATAMATION: Right. But what about the server side-
`is Java database-server and network—OS-indepen-
`dent, too?
`
`GOSLING: It depends. With things like databases, like Or-
`acle and whatever, there’s a standardized API [see sidebar,
`
`“Move over ODBC. l-Iere Comes_[DBC," page 32] that is,

`the Web page comes over, and here's this
`with circuit
`simulation in it.
`
`Somebody has to write that. And what tends to happen
`a lot is many applets get used over and over again. So, there's
`one applet that draws a chart, and the chart picks as a pa-
`rameter the URL to some data source or data stream, ifit’s
`
`going to be a live chart. And it puts the data in the chart
`[while its changing]. One of the nice things about doing the
`chart application as an applet is that it stays live. So if it's
`connecting to a database server that's got stock prices, then
`you get this chart up on your screen, and it's got the stock
`price diagram. But as the stock price changes, you see the
`graph move. [See related article in this issue, “How java
