Re-Learning Java Web Technologies

Hi
For the last 2 years, I have been developing ASP.NET applications. Therefore, I have not followed any new developments within Java industry.
However, now I just want to re-learn Java web technologies.
Therefore, could you kindly inform me whats the best book that can give me a good ground intp Java web / Enterprise development.
Thanks

Thanks for the answer.
When I was doing ASP.NET development, I found these 2 books useful:
http://www.amazon.co.uk/gp/product/1861008031/026-2514404-8364464?v=glance&n=266239
http://www.amazon.co.uk/gp/product/1861008163/026-2514404-8364464?v=glance&n=266239
These books showed how to develop a full working website with asp.net.
I wonder if there are similar books for Java. I am not a beginner with Servlets or JSP. I just want to know how to put together a full working website with the latest Java technologies.
Core Servlets and JSPs is definitely a very good book.
Kind regards

Java Web Services Developer Pack v1.2

I recently installed J2SE v1.4.2 Beta on my computer and it works fine with the platform, which is Windows XP Home Edition.
Now, I like to learn Java Servlet Technology and had searched through the downloads pages. I found Java Web Services Developer Pack v1.2. But I have doubt about this: Is there any problem to run Java Web Services Developer Pack on Windows XP HOME Edition? I learnt that Sun engineers had it tested on Windows XP Professional Edition.
I will appreciate any comments and opinions. Thanks in advance!

doesn't mean it won't work on home edition. just means that they probably think anyone who might want to use J2WSDP will prob have Pro...

Java Web Start Not Working

I am new to java and I am trying to learn Java Web Start. I know most of it, but I have a problem. When I post the file on my web server, it uploads fine. When someone views it though, it shows the source but doesn't execute! If anyone has an answer, please tell me!

As far as I know mime-type should be registered even on server side.
Somewhere (depending on the server) in your web-server config you should associate jnlp extension to mime 'application/x-java-jnlp-file'. If you have active code for download you can try to manually had the header 'Content-Type', just using response.setContentType('application/x-java-jnlp-file').
Try google something like 'server register java jnlp application mime type' (replace server with your actual server).
Good luck.

The Best Java Web Services Technology for Developing Web Services

Hi,
I am new to Web services world.
I read the java web services page . there are more than 6 technologies.
JAX-WS,
JAX-RPC,
JAXB,
SAAJ,
JAXP,
WSIT,
XWS-Security
I went through several documents on web services.
I could not get a clear idea of which technolgy to use.
Which Java web service technology will be the best to develop web services independant of language, platform.
or is there any 3rd party implemetations available ? for rapid development of web services.
Could anyone help me !.
Thanks in advance.

Which Java web service technology will be the best
to develop web services independant of language,
platform.
Java by nature is a cross-platform language, so if your focus is on the need for portability, the choisce of WS should not be a problem. However, each WS is best suited for paricular uses.
SAAJ, a low-level level API, offers much simplicity, but is not the first choice for programmers, as SOAP (Simple Object Access Protocol)messages need to be constructed piece by piece, making it a quite arduous code to program.
If you are not familiar with XML, your best bet would be to use JAX-RPC (Java API for XML-Remote Procedure Calls), as it hides the underlying detail from the programmer, in terms of SOAP and XML. The shortcoming with RPC-based WS is that it is "restricted to the local programming experience". Another failing is that assumes there is a network path- a reliability concern.
If your program will be contacting other services during downtimes, unlike JAX-RPC, JAXM is quite useful. However, your listing did not mention it, so I wont cover it.
JAXR is a client-side only API that acts as an interface between registries (not referring to JAXP)
I am not famiiar with JAXB, JAXP, WSIT or XWS-Security..
or is there any 3rd party implemetations available ?It depends on what platform you are used to. Assuming you are familiarized with the J2EE platform (now changed to Java EE SDK), the NetBeans IDE (either 5.5, 5.5.1 or the latest editiion) is quite useful. I am using 5.5.1, but have found that it is quite buggy, especially when adding WS operations, a core requirement of a WS. if you will be using to devlop a service for an immediate need, you may find the learning curve to be a bit high, in terms of getting to grips with how to use it. (Download link:
http://www.netbeans.info/downloads/index.php)
The IBM Autonomic IDE (or AIDE), based on the WSDM standard, includes 3 sub-tools, icluding the IBM Manageability Endpoint Builder which, according to their website, allows individuals to build endpoints to allow manageability interface exposure; Manageable Resource Browser and the IBM Manageability Endpoint Simulator. However, I'm not familiar with this IDE. (Download link: http://www.alphaworks.ibm.com/tech/aide/download)
The .NET Framework uses the Visual Studio IDE. For an unbiased comparison of J2EE and the .NET Framework in terms of WS, see http://www.webservicesarchitect.com/content/articles/hanson01.asp.
Apache Axis2, Geronimo and JiBX allows fast development of WS, or so the creators profess.
The PHP environment- you could try NuSPHERE PHPed. According to one website, with it you can develop a web service in under an hour.
I hope this was useful to you.

What's your strategy for learning Java technologies?

Or, in other words, how do YOU acquire knowledge that is necessary for implementing Java technologies?
After having spent one-and-a-half years developing an enterprise app, I've gained lots of knowledge about Java and some surface knowledge about its related technologies (JBoss, Hibernate, Ant, XDoclet, NetBeans and probably some others I can't think of at the moment).
I'm now realizing that -- although the standalone prototype version of my program is growing mature -- I've still got lots to learn for refactoring it to a web platform. For example, I 've done small test projects using Servlets, but haven't done any work with JSP (or HTML for that matter) yet.
Now, I'm sure I can learn JSP etc., but the questions I ask myself are: how long will it take?
It's a rhetorical question of course (I don't expect an answer from you, the reader) However, it's an important issue because the months or years I spend fumbling around learning these new technologies, are time I could otherwise spend on the business logic and functionality of my program.
So, how do you guys acquire knowledge of technologies? Official training perhaps? Or do you simply experiment until it works? Or do you rely on your company's knowledge base (e.g. someone in your company knows how it works)? Or do you get prototypes built from someone who already knows how it works?
I�m really curious about this and would appreciate your thoughts.
Thanks in advance,
P

Well, it seems like most of you simply read the
various texts and try the vendors' examples. I'm
surprised that no one mentioned ever having bought a
prototype application from the onset. "bought"? What's that mean? You don't buy prototypes. You download evaluation versions, maybe.
I try to find sample code and tweak it to see the effects. Otherwise, I start writing small sample code an build on that.
I consider myself a reasonably competent core Java
programmer, but I had serious difficulty configuring
and merging its related technologies. There were so
many disjointed pieces of instructional information
that the additional research time really hurt our
budget severely. Not an uncommon thing, I'm sure. There's a lot of stuff. But don't bother learning all of it. Not in detail, at least. It's a good idea to familiarize yourself with the names of packages/libraries and what they do. But only really learn what you need to learn for what you need to do. The next project you will probably need other things, so you learn them then.
bsampieri,
I've setup Tomcat and tried the examples--in fact, I
normally follow tutorials for all products I hope to
use. Problem is, the examples and tutorials never
address my specific needs. So, I usually inch toward
my goal by spending weeks or months in forums to
continue where the tutorials leave off. Anything complex is going to not be there.... the trick is to identify pieces that you can pull out to build more complex apps. And the fact that JSP/servlets have the issue of being compounded by all the HTML/CSS/JS and HTTP protocol ... I don't want to say limitiations, exactly... Well, it just makes things more complex and harder to know what you need.
Perhaps you guys are much faster and smarter than
I...or you have a much bigger budget :)Probably not... on either account.

Java as a Web Technology is Living on Borrowed Time

Java’s change in market status from a viable web technology to what it is nowundesirable legacy codeis astonishing. Oracles recent patch for Javas zero-day flaw puts one more nail in the coffin. Zero-day status is assigned to flaws that are currently being exploited by hackers, and for which there is no available fix. A little […]

Well to be brutally honest, I think you'd be better off sticking with Flash if this is a critical project... it would be a great exercise for learning Java, but would probably take w-a-y-y-y-y-y more effort than doing a similar multimedia presentation in flash.
(I haven't used Director, so can only talk about Flash here) - as you know, Flash is really a very powerful authoring tool that allows the user to do very complex animations very easily, whereas Java is a lower-level programming language that is infinitely more flexible, but comparatively more developer-intensive when it comes to producing user interface stuff. Java might be a viable option if you have to do stuff that flash can't, like very complex interactivity, or pulling info from a database etc (although maybe Flash 5 can even talk to databases now??? I don't know)
You can get tools to help you build Java user interfaces using "drag & drop" methods, and these tools will automatically generate the code for you, but (a) this means you're not really learning java, and (b) flash would still be less labor-intensive (and probably more impressive to your end users)
In summary - I'm not knocking Java or Flash - I love 'em both; it's just that Flash is better suited for certain things, and Java is better suited for others...
PS - nice website, but Portfolios shouldn't have an apostrophe before the "s" ;-)

I am looking for Java-based technology for building nice looking Web apps

Hi everybody,
As written in subject - I would like to use some nice web technology, based on Java. I would like to build good-looking web pages. I have tried a bit of Dojo or JQuery (generally this is Ajax I think). Could someone point me what is the relation between Java application/technology and presentation layer of the application? For example, could I easily build nice Web application only with JSF? Or should I connect it with some Ajax-based library?
If Ajax is best solution - what are your favourite Ajax implementations?
What about other technologies: portlets, EJB? Thanks in advance for some info - even general.

JS/Ajax is entirely client side.
In JSF world there are several component libraries with builtin ajaxical (and skinnability -this also covers "nice looking" as you say) support, such as RichFaces and IceFaces. Give their homepage and demo's a look.
If Ajax is best solution - what are your favourite Ajax implementations?I myself have jQuery on #1.

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

New to Java Web Start technology - unable to start JWS

I am new to JWS, and started with sample programs given at JWS product page.
I compiled the files and created the .war file and copied that file into the DOCUMENTROOT of my Web server. Also I copied the .jnlp file into the same location. After that I created a .html file in the same location which provide a link to .jnlp file.
Now, when I launch the html file, and click on the link, JWS window should have been launched and the application should have been started. But, what I see is the contents of .jnlp file on the browser.
What might be the problem? Please let me know the solution...
I am using Apache Web Server on a Win 2000 system. Also I modified the mime.types file under web server to include the following line:
application/x-java-jnlp-file JNLP

Setting Up a Java Web Server on Linux

Greetings,
After a lot of reading, I've decided to learn Java server-side technologies (I already know Java (desktop)
but with little experience) in order to develop my database driven dynamic website projects.
However, I'm completed lost between the hundreds of acronyms related to Java and the "thousands" of technologies involved.
Google hadn't help me understand what they really are and how they relate with each other.
Even though is easy to find what they stand for and some faqs/descriptions, it hasn't been enought to clear my mind.
I want my webserver application to do, among other things, the following:
Retrieve Data from a database, do generate dynamic html files.
Story Data on the database, from html forms.
Send automaticly emails for multiple users. (newsletter for example)
E-Commerce.
Html graber/parser (I don't know if this is the right word, I mean a program that for example, goes to a URL with an html
table, and stores that information in a database table, as long as the format didn't change).
Real Time Chat feature.
Database connection pooling, caching, and other important optimizations.
I'm not asking for how to develop or configure this features nor what components and programs, must be installed.
At the moment, I only want to know how to set up a Java solution that will support them when they are needed.
*** Linux ***
I want to set up my webserver on a linux distribution.
In that respect, I don't know if I should choose RedHat or Fedora Core.
I've heard that fedora is better for a webserver (having in mind that Red Hat Enterprise AS/ES aren't free).
But I've read in several sun turorials/webpages references to RedHat (on a J2EE context).
So I'm wondering if is better to go for Fedora or RedHat. Are there pros & cons? They equally support Java?
*** Technologies ***
Then in starts the acronyms problem.
What do I need to install, in what order, for what?
Some aconyms and technologies, I have read about but don't fully understand are the following:
Apache
J2EE
J2EE 1.4 SDK
SUN Java System Application Server Platform Edition 8
J2SE 1.4.2 SDK
SUN Java Enterprise System
Tomcat
Struts
Cocoon
JBoss
I already know J2EE is only a specification. What implements that specification? Sun Java System Application Server?
J2SE SDK? or Tomcat?
What is the role of each technology, namely Apache, Tomcat, Sun Application Server?
What is the Sun Java Enterprise System?
How do Struts, Cocoon, JBoss relate to Java?
Which of these technologies are mutually exclusive (analogous)?
*** Doubts ***
Then, I have some doubts that are keeping me from starting to study seriously the important techonologies, because I don't
want to lose lot's of time and effort learning them to after a dillusion start everything again with PHP (the language
which make me think and read a lot before going for Java). To keep this from happening, I would like to know the following:
I want to use Java for developing websites with commercial/profitable use for my company, in some throught e-commerce,
and in other by banners. I want to do everything by the book, with required licenses.
------ Java is Free?
Is Java Completely Free or it might be possible that at a certain point, when I need some component or library,
multi-machine webserver, performance or security for high-traffic I will see "buy now" instead of "download now"?
For what they may "ask for money"? and what are the disavantages if I can't buy?
For example, "Java System Application Server Standard Edition 8.1 2005Q1" and
"Java System Application Server Enterprise Edition 8.1 2005Q1" cost $2.000 and $10.000 respectively. That is money.
(http://www.sun.com/software/products/appsrvr/index.xml). What are the disavantages if stick to the free edition?
Features like (from sun site)
Standard Edition:
Extends the capabilities of the Platform Edition to provide secure, remote, multi-instance, multi-machine management.
It is aimed at high-volume applications and Web services.
Enterprise Edition:
Further extends the capabilities of the Standard Edition to provide continuous availablity for applications and
Web services. It is aimed at business critical, high value applications and Web services.
Suppose I achive lots of traffic and I keep the free platform edition.
I won't be able to have a multi-machine webserver set up correctly?
What are the drawbacks? How big are the performance penalties?
------ Technologies Availability
Finnaly, I have the idea (I don't know if it's accurate) that there are Sun versions and Open-Source Free versions
of doing or supporting the same Java related thing.
Despite the way I choose to set up a Java webserver, I will always have all J2EE techonolies like:
Java API for XML-Based RPC (JAX-RPC), JavaServer Pages, Java Servlets, Enterprise JavaBeans components,
J2EE Connector Architecture, J2EE Management Model, J2EE Deployment API, Java Management Extensions (JMX),
J2EE Authorization Contract for Containers, Java API for XML Registries (JAXR), Java Message Service (JMS),
Java Naming and Directory Interface (JNDI), Java Transaction API (JTA), CORBA, and JDBC data access API.
I really appreciate some help. I could learn the basics of all this "stuff" before asking. But the point why I'm asking
is precisely not starting to learn something I may won't use. Obviously, I will have to make a lot of reading during maybe
months before writing the first line of code of my projects, but being certain that it will fit my needs.
I will be very thankful if you can enlightme in my fedora/redhat, setup, free/cost and technologies avaibility issues.
Thanks Beforehand,
Pedro Vaz

Apache is a free Web-server.
Tomcat is a servlet (and JSP) container. It can be stand-alone or can be used together with a Web server (like Apache).
J2EE's scope is much wider than the servlet stuff, but a standalone Tomcat is a good starting point to servlets and JSP.
One of our "real-world" applications is run by a standalone Tomcat using POI and Velocity. I did not regret this architectural decision.

Java Web Start and DeployDirector: What's the difference?

I am the product manager for DeployDirector at Sitraka (now part of Quest Software). I'm NOT in sales; I'd simply like to provide you with some information.
From talking with DeployDirector users and evaluators, and from my own discussions with the folks at Sun, I have discovered that there is great deal of confusion about the difference between Java Web Start and DeployDirector. I'd like to clarify this by periodically posting some information about the two.
Though the products seem similar in concept, they are designed for different purposes. They both deploy, auto-update and manage the JRE for client-side Java applications, but beyond that, they are quite different.
Java Web Start is ideally designed for applications deployed over the Internet, where application-provider trust is an issue. Why? The security sandbox guarantees that application can do no harm. (There's some good information about Java Web Start and sandbox apps on ScheduleWorld at http://www.scheduleworld.com/itsYourLife.html) Web Start's architecture simply consists of a client piece that interprets a JNLP file. Because of the sandbox and its simplicity, I believe JWS is best used for independent software vendors, independent developers, etc.
Because DeployDirector is ideally designed for internal enterprise applications, it does not enforce the security sandbox. Trust is not an issue here, because internal users typically trust their internal IT group. DeployDirector's architecture consists of both a client and a server piece, which allows us to support more complex deployment and update scenarios (e.g., scheduled and optional updates) and applications management capabilities like rollback, reporting, exception monitoring, authentication/authorization out of the box. All of this is configured through the DeployDirector administration console.
In some situations, DeployDirector may be unnecessary overhead. In other situations, Java Web Start simply does not provide enough capability and building in this into Web Start can be difficult.
If you'd like more information, we have whitepapers and case studies (including one specifically about DeployDirector and JWS) available on our website at http://www.sitraka.com/software/deploydirector/
If you'd like to discuss some of these differences, or if you have questions about DeployDirector, feel free to email me directly. (Or post here, of course.)
Thanks,

Hi Gerald,
Given what I know about your emnity towards DeployDirector (which is clearly illustrated in this thread: http://forum.java.sun.com/thread.jsp?thread=348061&forum=38&message=1446155 that was evidently a response to this article: http://www.javaworld.com/javaworld/jw-11-2002/jw-1122-autoupdate.html) I'm going to take a (pardon the expression) "don't feed the trolls" approach here.
I'm simply re-iterate that JNLP, and its implementations such as Web Start and OpenJNLP, are designed for a very different set of users that DeployDirector. The differences in functionality between the two products reflect that.
The enterprise has different requirements in a deployment mechanism for its internal, critical applications than software vendors and independant developers. DeployDirector addresses the requirements of the enterprise. Frankly, most of our recent customers only chose to buy the product after initially rejecting it and (unsucessfully) attempting to use JNLP and Web Start. Sometimes people only learn the hard way: different users have different requirements which are suited to different tools or technologies.

Why Java is Technology?

Hello everyone,
I m very new to java, i m still learning java. At the beginning itself i got a doubt that why everyone calls java as a technology not language. Please let me know why is Java is called as technology not Programming language.

All that is true, but the word "technology" gets overused.
For example, on the page "Update: An Introduction to the Java EE 5 Platform"
http://java.sun.com/developer/technicalArticles/J2EE/intro_ee5/
I searched and found these uses of the word technology. How many uses
actually add meaning to the sentences in which they appear?
The sections on web service support and JavaServer Faces technology have been greatly expanded
Mapping Java technology classes to XML
Mapping Java technology classes to databases
Web applications that use JavaServer Pages (JSP) technology only
Example 1A shows the Java technology code for a hypothetical session bean using EJB 2.1 software.
In fact, this API can also be used outside the Java EE platform in plain Java technology programs
Because entity beans are simple Java technology classes, they can be packaged virtually anywhere in a Java EE application
Now it's as easy as placing the @WebService annotation on a Java technology class.
When starting from Java technology classes, JAXB 2.0 can generate XML Schema documents that are automatically embedded inside a Web Services Description Language (WSDL) document
Example 6 shows how the mapping of Java technology classes and methods to web services
As the standard API used to bind XML documents to Java technology objects,
The number and size of the Java technology classes generated from a given Schema has been greatly reduced.
Example 9 shows a Java technology class annotated for use with JAXB 2.0.
A common issue in developing some Java technology classes first and defining their mapping to Schema later is that some common Java technology types do not have a standard representation in XML Schema.
The JavaServer Faces technology establishes standards for component design and as a result has created a new market for third-party JavaServer Faces technology components.
One or more JSP technology pages

NEwbie at JAva Web Services

Hi guys,
I am extremely new to Web services using Java. I would say I am reasonable competent with java language.
I would liek to learn how to do a interesting website for myself which employs web technologies and real time dynamic interaction with users of my website. I do have experience in doing simple static webpages and I am running my own webserver (Apache HTTP Server).
I would like to implement some mroe advanced web services on my webpage using Java ( since I laready know Java).
I do not know where to start. Do I start with JAva Servlets ? JSPs ? UDDI ? COM ? XML ???
Please kindly advise.
Regards
David

I think Java servlets is enough for a personal site.
