depending on your definition of mature but generaly speaking, in my opinion, yes.
my application has been running in production for several months now.
i would say its a small-mid sized application.
no problems what so ever that i consider major up until now.

i have a website up and running. 99% JSF tags (1% JS)
works like a charm.
however, no real load on it yet.
deployment was nothing unusual also.

Are Web Start and Swing stable and mature technologies?

Hi there
I'm currently looking at using Webstart and Swing as technology of choice to offer more "ap-like" functionality on our company extranets, without needing serious bandwith. (bandwith in our part of the world is veeery expensive)
I'd appreciate some advice:
1) Is the Webstart download still about 6MB as it was at its inception?
Must Webstart be downloaded everytime one upgrades your browser?
2) Is it generally easy to develop using Webstart and Swing for someone with general Java (applet) development experience? (reasonable learning curve)
3) Are there a lot of people using Webstart and Swing - ie has it proven itself to be stable and "development friendly", does it deliver on its promises of enabling one to develop fast client-side Java "apps".
Bottom line, I need to know if it's worth my while to invest in developer resources for Webstart and Swing to get added functionality on our extranets; or should we rather keep using PHP/ASP, SQL , DHTML and be happy with the functionality these technologies bring to our user interfaces.
Any input would be appreciated!

I'll give a summary answer -- I'm not an expert on Swing and Java Web Start, but I've used them both to some extent.
Java as a whole -- mature and stable, but a heavy download. Practically speaking, if your users use Windows, they'll need to download a JRE from Sun rather than go with Microsoft's outdated and never-to-be-updated Java VM.
Swing -- mature, stable. A good way to develop platform-independent rich clients. It's hard to make a real desktop application out of DHTML and JavaScript, but desktop applications are what Swing is all about. They won't look like Windows apps, but they can be a lot more interactive than a webpage.
Java Web Start -- usable but not yet mature. 1.0 has shortcomings (which is typical of 1.0 products) that are being addressed in 1.2, which is part of J2SE 1.4.1. Installation in Windows, in particular, should get easier, with an ActiveX control.
In all cases, you face large downloads (10 MB or so) to install Java Web Start or a JRE, followed by reasonable downloads (10-200k, depending on the application) per Java Web Start application.

Q: is the SOA Suite a mature technology?

A colleaque and I have been playing araound with the SOA suite the last copule of weeks. My colleaue mainly concentrated on the BPEL, while i did the ESB part.
Even though I did some very simple scenarios, it seemd to me that theres a lot of errors/bug. For instance when using native sequencing, you have to manually edit some XML files. Another thing,- I have to deploy my services more than once to make sure it works. Of course this is all new to me - so I'd expected some beginnes difficulties - but never the less - I'm a bit worried about recommending this technology to my manager.
So the question is: does this work or not?
I use the Soa suite 10.1.3.3 on Oracle DB XE.
Kind regards, Henrik

Another reason to wait for 11g if you want Oracle SOA is problems with upgrading existing processes from 10.1.3.3.0. We used 10.1.2 before and upgraded to 10.1.3.3.0 and had to reduce the number of processes from about 150 to ~30 due to problems with converting projects in JDeveloper and partly changed behaviour of BPEL. Old processes often stopped working and required mostly day per process to debug and fix. We simply couldn't do the converting for 150 days.
Its a pitty though that Oracle doesn't plan to support BPEL 2.0 in 11g, as if they were affraid to touch the original code developed by Collaxa. Does anybody know whether 11g will have better support for WS-* features, like WS-Security in outbound messages (arriving from web service), generation of WS-Policy assertions in wsdl?
Other problems that one needs to take into account when considering 10.1.3.3.0 are:
- JDeveloper 11g will probably be incompatible with BPEL 10.1.3.3.0, so you will be stuck with JDeveloper 10.1.3.3.0, since no newer release of 10.1.3 is planned.
- in 10.1.3.3.0 propagation of security context into EJB is not functional. Although EJB invocation is supported from BPEL, methods will always execute under the same credentials which defeats the advantages of EJB. Hopefully Oracle will fix this problem in 11g.
- incompatibility between BPEL 10.1.3.3.0 and Oc4j 10.1.3.3.0 web services when using WS-Security UsernameToken. Oc4j web services with WS-Security cannot be invoked by BPEL without manual editing of oracle web services xml. This editing has to be done every time something is changed in web service since then the xml is overwritten.
- database connection pool used by BPEL is not periodically checked for "select * from dual", so invalid database connections can be passed to BPEL process. This becomes a problem if you need to gradually restart your DB cluster nodes. I have even noticed once that a DB connection was passed to BPEL which did contain uncomitted data from previous process (ending with exception), which resulted in seeing data that didn't exist in database.

Mac OS X Technologies in Operating Systems Categories?

It would be great to have the Mac OS X Technologies Category linked inside the Mac OS X Leopard, Tiger, and Panther and earlier categories. This thread shows a classic example of why people are lost without such a link.

JDev 10.1.2 - JSF 1.1_02 - error hangs entire application

Hi,
I'm building my first JSF application and an issue has arisen during testing which has us all stumped! Whenever an error occurs for a particular user, the entire application then falls over and all other users then see (different) error messages too.
Let me try to describe the scenario in detail.
1. 10 users are using the main page of the application quite happily.
2. Another user logs in and visits a different page in the same application. This page contains a bug.
3. The application serves the error page to this user as an unhandled exception was thrown when processing the request.
4. The other 10 users also get the error page even though they have not visited the buggy page! The application has fallen over and requires the container to be restarted.
Steps 1-3 are obvious, but I don't understand step 4 - why should the application fail to continue serving bug-free pages to all other users? Is this the expected behaviour for JSF applications? (Other platforms I've used don't behave this way.)
I can easily replicate this issue by introducing a typo to a component's EL binding. The initial error message is
javax.servlet.jsp.JspException: Error getting property 'thisisatypo' from bean of type com.mypackage.MyBeanAll other users then see a secondary error message:
java.lang.IndexOutOfBoundsExceptionOther applications on the app server are not affected.
Is there a way to configure or recode the application to better handle exceptions so that the application itself doesn't hang and other users can continue to use it? Is it a threading issue? Or is this an issue with the application server, which requires reconfiguration to fix it?
A thread on Sun's JSF forum mentions a similar issue, but no-one has answered it: http://forums.sun.com/thread.jspa?forumID=881&threadID=5049367
My environment:
JSF: v1.1_02 (Sun JSF RI)
IDE: JDeveloper 10.1.2.3.0
Java: 1.4.2_06
App Server: Oracle App Server 10g (OC4J 9.0.4.0.0)
(Upgrading to more recent versions of JSF or application server are not options at the moment - my organisation has already scheduled upgrades sometime within the next 12 months or so, but I cannot bring them forward!)

Hi Frank, thanks for your reply.
I did indeed manually configure JSF for JDev 10.1.2 & Oracle App Server 10g (OC4J 9.0.4), following the instructions provided by Oracle at [http://www.oracle.com/technology/products/jdev/howtos/10g/jsf_howto/jsf.html|http://www.oracle.com/technology/products/jdev/howtos/10g/jsf_howto/jsf.html]
I have just spent some time porting my application to JDev 10.1.3 & OC4J 10.1.3, as you suggest, and I can confirm that the issue does not appear using this platform.
However, my organisation does not have this version of Oracle App Server in production. As I indicated in my first post, an upgrade from 9.0.4 to a newer version (tbc) should occur sometime in the next 12 months, but we undertook this project on the basis that JSF would work on Oracle App Server 10g (OC4J 9.0.4), as per the "how to" above.
If this is not the correct forum to pursue this issue, where, or with whom, should I?
Many thanks,

Help w/ JSF vs. JavaScript+CSS+DHTML debate

Hello,
I need to quickly obtain some facts to help guide the direction of a new project.
The entrenchment here seems to lean toward JavaScript, CSS, and DHTML to provide client-side validation and presentation enhancements. Personally, I am more receptive to JSF but I am in unfamiliar territory when it comes to web technologies.
I need to know how JSF compares with using JavaScript, CSS, and DHTML. Does JSF alleviate the need for these technologies? I have a lot of information on why JSP Model2 is better on the server-side but I am really needing some data on the client-side presentation aspects (validation, sexy widgets, etc).
Thanks in advance for anything anyone would like to share.

Thanks erikbuchez. So would it be correct to say that
the JSF HTML (or is it HTTP) components are
implemented with JavaScript/CSS/xHTML? In a way, yes. JSF defines a set of Standard User Interface Components, a Standard HTML RenderKit for those components, and a Standard HTML RenderKit Tag Library. The components, RenderKit and tag library are implemented in Java and run on the server, but together they end up generating HTML/CSS/JavaScript interpreted by your Web browser.
As a follow up, I assume one can override/extend the
existing components or create new ones as needed by
extending some appropriate base class?Yes, you can derive from existing components and renderers or create your own (in Java).
If I'm getting the idea here, you use the expression language in
your JSPs and make use of the template library to get the nitty
gritty stream back to the browser?Not sure what you mean here, but if you mean that you write JSP pages using JSF tag libraries and let JSF generate the HTML/CSS/JavaScript back to the client, you are right.

Installing JSF on a Windows box

Hi. I've got a Windows XP Pro system and am using Oracle JDeveloper. Sorry for the stupid question, but how do you install the Sun JSF technology on this system? I did some searches but only found specifications for download and not the actual technology. For example, this page had links to docs -- http://java.sun.com/javaee/javaserverfaces/download.html
I'm doing something wrong; your help is much appreciated. Thanks.

Quted from the link you've posted:
You can get the JavaServer Faces 1.2 reference implementation in one of the following ways:
* Download Java EE 5 SDK.
* Download the open-source Java Platform, Enterprise Edition (Java EE) application server, available through the GlassFish project, available from java.net.
* Download the implementation JAR files separately from javaserverfaces.dev.java.net if you want to use the implementation with other containers.

Trivial JSF 2.0 URL to Page mis-match

Say I create two Java Server Faces pages that just link to each other. You'll notice that the URL's get mixed up. When I click from page 1 to page 2, the url continues to say page 1, and they remain reversed for the rest of time... This is useless for book marking. Is there a reasonable work around for this bug?
<html
     xmlns="http://www.w3.org/1999/xhtml"
     xmlns:f="http://java.sun.com/jsf/core"
     xmlns:h="http://java.sun.com/jsf/html">
     <body>
          This is page one!
          <f:view>
               <h:form>
                    <h:commandButton action="pagetwo" value="forward"/>
               </h:form>
          </f:view>
     </body>
</html>and page two is here:
<html
     xmlns="http://www.w3.org/1999/xhtml"
     xmlns:f="http://java.sun.com/jsf/core"
     xmlns:h="http://java.sun.com/jsf/html">
     <body>
          This is page two.<br/>
          <f:view>
               <h:form>
                    <h:commandButton action="pageone" value="back"/>
               </h:form>
          </f:view>
     </body>
</html>Since this is such a basic example it does leave me wondering if JSF 2.0 is a good technology to use to build a dynamic web site!

This is normal for JSF. Let me explain how this happens. When a page is submitted using a JSF commandXxxx component, it is not known at submission time what page will be the result. So the form is always written to submit back to the page that was rendered. The request comes in; the view is restored; validation and conversion occur (if they fail the original view is re-rendered); actions are fired during the execute application phase; the result of the action is fed to the navigation handler to determine the next view; the next view is rendered (or the original view is re-rendered). So this problem is an inevitable result of the way JSF was designed.
That is not to say there aren't ways around it. In JSF 1.x you could use the <redirect/> directive in the descriptor for the navigation rule. This would cause the server to issue a redirect response for the new view and thus the URLs would align. There are side effects however (some positive). In JSF 2.0 you might not have a descriptor for the navigation in question, I am not sure how you accomplish the same thing without creating an entry in the faces-config.xml.
Now I will get to the really good stuff, which I think is what you will desire. There are libraries to create bookmarkable, "pretty" URLs for your JSF application. Try googling PrettyFaces.

Does JDev support portlet development for non-OracleAS java containers?
Portlets developed in JDeveloper may be deployed to another application server that supports portlets.
Are the Web Center Suite / Portlet Development tools a plug-in for Jdeveloper?
The WebCenter extension for JDeveloper is pre-configured in JDeveloper.
Currently I use JDeveloper ADF BC / JSF and deploy to Tomcat; I'd like to include portlets in our web application.

Beginner confusion: what technologies to use for a new web application ?

Hello,
Being a beginner to JDeveloper , I am very confused because it looks like
there are so many alternatives : JSF vs ADF faces vs Swing,
EJB vs Toplink vs ADF business components.
I am having trouble with determining which of these alternative technologies
would be the most productive (in terms speed of development).
Which of those technologies are recommended for a small web-based application?
Thanks,
Adrian Maier

For my projects, the technology is chosen (from JDeveloper's available technologies) that best suits the requirements for the project. In my experience ADF Business Components are awesome if there are lots of database tables involved, but you need to have the patience to sit down and learn the technology intimately if you wish to perform complex tasks with them.
As for JSF vs. ADF Faces vs. Swing...
ADF Faces is like a framework built on top of Java Server Faces to supply a more rapid development process than just solo JSP/JSF. Consequentially, I find that ADF Faces sort of limits my desire for certain power over the application front end though...
In the end, what you start with depends also on what you know. If you are new to JSF/JSP then I would start there. ADF Faces became much more intuitive to me once I became educated on the base technology that it works with.

Difference between JSP and JSF

What is the difference between JSP and JSF?
Is it necessary to learn JSP before starting with JSF?

JSP is a view technology providing a template to write plain HTML/CSS/JS in. JSP supports Java based taglibs to generate output and/or control the page flow dynamically. A well known example is JSTL. JSP also supports access to backend data with help of EL (Expression Language).
JSF is a component based MVC framework which provides taglibs for use in JSP, the JSF core tags in <f:xxx> and the JSF HTML tags in <h:xxx>. Those tags generate HTML output and are tied to JSF component tree in the server memory so that the FacesServlet can work on them to gather request parameters, validate/convert them, update the model values (javabean properties), invoke some actions (javabean action methods) and render the response.
You can use JSF on top of either JSP or Facelets. Facelets is another view technology. JSP is ancient and has its shortcomings when JSF comes into picture. Facelets is designed with JSF in mind and much more well-suited for it and provides great templating/composition capabilities to reuse specific groups of components without the need to wrap them in another custom component (so that you don't duplicate the same code over and over, e.g. label+input+message.
