Is it worth learning JSTL?

Hi,
I know JSP and use it everyday.
Now I want to generate my html pages fully with taglibs, but I wonder if it is worthwhile to learn JSTL, or just stick with Struts taglibs, or some taglibs from another MVC framework.
What would be the advantages and disadvantages of learning JSTL?
How does the efficiency of the JSTL is, compared to just plain JSP with scrptiles?
TIA,
Gabriel

I have a slightly different take on this.
Everyone here is a developer, and so JSTL is "easy to learn" since the concepts of control flow etc, are second nature. However, my experience is that the intended audience for JSTL (i.e. web designers, right?) rarely find it that easy. So I question the value of this standard library for all but the most technical/creative designers.
In my personal real world, writing a tag takes less time than the discussion or design of one to meet the needs of that audience.
In my own applications, I provide application-level custom tags designed for that specific application according to the current wants/needs of the designers. Obviously I have built up a library of generic tag code, which i extend to deliver against the latest request... usually in less than an hour.
I don't know if you have tried to explain the concept of an iterator to a non-programmer, but in my experience it saves a lot of messing around and a lot of time-wasting "how do i" questions to give them the functionality in a way that they can understand, rather than the way dictated by concerns that they never face in the usual course of their work (not to mention the massive reduction in broken markup when things -- inevitably -- change in their design).
A simple example:
<table>
<myapp:chat-list>
<tr><td><myapp:chat-user property="username"/></td><td><myapp:chat-user property="logged-in"/></td></tr>
</myapp:chat-list>
</table>/k1

Carrier in SAP: Is it worth learning MDM?

Hello Everyone,
Looking for a carrier guidance please let me know your thoughts.
I'm a J2EE Developer specializing in Content Management systems/Portals with about 8 years of experience.
Looking for learning new skills specifically learning vendor(canned) applications which would also require J2EE Experience so that i can use all my J2EE experience and as well learn new applications to better position myself in the consulting market.:-)
Started looking at the SAP Netweaver Technology and all the products stacked against key areas of the Netweaver Architecture. Lack of my experience in SAP landscape made me get confused on what product to pick and learn to position myself in and also was not sure about whether one would really get any jobs after going through all the learning with no experience in that product.
So wanted to reach out to all of you and see what you guys think and suggest after reading through my thoughts and confusion.
Getting into emerging technologies in SAP made more sense since there will be opportunities for people with less or no experience in sap landscape :(.
Do you guys think it is worth learning and planning a carrier in MDM?
How does the feature look for SAP MDM?
How should one go about planning to get to the MDM world. What other skills one should know that would help ?
Thanks All for all the help.

Hi Rajesh,
MDM is truly a new way of solving old data management problems, Morris said. Traditional information architecture focuses on the infrastructure and design of systems in a company, and can include practices like synchronizing data around a hub. These architecture approaches are much more monolithic than MDM. Applied MDM, which includes data governance techniques, along with MDM infrastructure tools, represents a more flexible way of approaching the problem.
Andrew White, research director at Stamford, Conn.-based Gartner Inc., agrees that MDM is a legitimate solution for data management difficulties.
"Information architecture is lost," White said. "We're realizing that we need a different kind of governance model."
MDM is "80% old stuff and 20% new stuff," White said. The "old stuff" is technology expanded from product information management and CDI tools, as well as some of the data definition concepts of metadata management. The "new stuff" is a major emphasis on data governance and new MDM tools, which are different from anything the industry has seen before, White said.
MDM software, from companies like IBM, Kalido and others, acts as middleware, in essence giving systems a commonplace to look for approved data definitions. White describes this MDM software as an "intermediate tier between physical data and the consumption of that data." Combining software and data governance best practices, MDM is an innovative approach to solving data management problems, he said.
It's only a matter of time before companies start to adopt MDM, White said. The coming year will be one of awareness, and the peak of spending will come in two to three years, he predicts.
Between emerging technologies like SOA and RFID requiring consistent data definitions and motivators like heavy-handed fines for inaccurate reporting and non-compliance, analysts like Morris and White feel that MDM is a critical component to many business initiatives.
Master data management is not a technology market, but a business capability," said Rob Karel, principal analyst with Cambridge, Mass.-based Forrester Research Inc. "All of the vendors branding themselves as an MDM solution, I liken to comparing apples and Volkswagens. They're all very different pieces of the larger complex technology puzzle that's required to solve the master data management capability."
Vendors from across the IT landscape emerged in force in the last few months, joining such players as IBM, SAP and Burlington, Mass.-based Kalido Inc. in announcing MDM products. Dayton, Ohio-based Teradata partnered with Dallas-based i2 Technologies Inc. for its new Teradata MDM platform. Other announcements amounted to repositioning and re-branding. Product information management (PIM) vendor TIBCO Software Inc., based in Palo Alto, Calif., announced its Collaborative Information Manager MDM application. Customer data integration (CDI) players made their move as well. Redwood City, Calif.-based Purisma Inc. updated and re-named its "data hub," and San Mateo, Calif.-based Siperian Inc. emerged with a new "customer-centric MDM" hub. Other pure-play vendors and big players alike have scrambled to use MDM label.
Of course, every vendor has a slightly different take, and the relative infancy of the MDM discipline makes product comparisons tough. Buyers should be wary of any vendor that claims to solve MDM problems with just one tool -- an impossible feat, Gartner and Forrester analysts agreed.
Forrester: Evaluate your MDM ecosystem
Karel introduced the concept of an "MDM ecosystem audit guide," a tool intended to help companies identify technology components that should be part of their data supply chain.
"MDM is a capability which will cross multiple technology platforms," Karel said, "because information is being captured, managed and consumed across many platforms."
An MDM capability may include processes and technologies such as data governance and stewardship, data quality management, integration tools, service-oriented architectures -- as well as systems that help manage master data definitions. Ultimately, successful MDM will be achieved by combining a wide variety of technologies and applications that create, manage and consume master data. Some capabilities might already exist in a company, Karel said. In fact, he added, companies could conceivably manage master data with no tools bearing the MDM label at all.
"If you knit together some of these disparate tools [that you already have] with custom code and random wrappers, you can create an MDM solution for your company -- it just won't be pretty," Karel said. "The vendors that will be successful are the ones that [can] create a more seamless administrative experience and the ones that allow you to leverage your existing investments."
No vendors really fit that description today, though some, such as IBM, are further along than others, Karel said. And there are more mature sub-segments of MDM, namely CDI or PIM, with vendors that have successfully addressed the problems of managing a specific kind of data entity. But, he said, a true MDM capability should address multiple kinds of data entities -- not just customer or product -- and that's where the complexity comes in.
Gartner: Consider the MDM continuum
The Gartner study placed vendors on an "MDM continuum," according to Andrew White, study co-author and research vice president with the Stamford, Conn.-based analyst firm. The continuum looks like a horizontal line, with "MDM niche" vendors on the left, "MDM generalists" on the right, and infrastructure giants Oracle and SAP in the middle.
The niche vendors on the extreme left of the continuum solve complex problems in certain industries or domains, White explained. These products can handle the complexities of very specific kinds of entities, such as customer or product data. They can potentially manage thousands of attributes and hundreds of hierarchies and are suited for operational purposes. This is where PIM and CDI vendors fit in, he said. Gartner placed IBM, Siperian and Wayne, Penn.-based PIM vendor FullTilt Solutions Inc. on this end of the continuum.
Products that appear closer to right side come from generalists and help companies get a single view of many different data entities, White said. These products are probably more appropriate for analytics and business intelligence uses. Generalists' products handle many different kinds of entities with relatively low complexity -- for example, labeling many master data objects with a low number (say, five to 25) of attributes. Kalido; Hackensack, N.J.-based Data Foundations Inc.; and Paris-based Orchestra Networks appear on this end of the continuum.
The study was specifically presented as a continuum, not a ranking, White said. Like all IT programs, the selected MDM tool should fit a company's specific problem, and legacy vendors might not always be the best choice, he cautioned.
"Vendors are making hay with [MDM]. They're all calling themselves MDM vendors," White said. "Customers have to be very careful. It's not that one MDM vendor is better. It's really about form fitting function. Where is your business? What is your particular problem of the day, and what will your problem be next year? Then figure out which data is most important, and look at that part of the continuum."

UML2 is it worth learning?

Hello,
I am currently attempting to learn UML2 standard in a class I am taking. It seems that there are a lot of benefits and downsides to the modelling procedure.
I wanted to ask the developer and the academic community about how they view UML2 and how effective it is from an industrial point of view. I failed this module last year. The professor taught it from a purely academic point of view and although there were some good things about the ADLs (Architecture Description Languages) it did not seem very relavant to the industry but I could appreciate how it might be applied if one were to take an obscure view on matters e.g connectors and components in Wright and CSP (academic languages) . My current teaher not the guy I failed under informs me that UML2 is also affected by academic research.
He is also very keen on MDA (Model Driven Architecture). I have already read the gigantic post where jschell and SoureError duke it out round after round about process modelling and formal techniques. I am only interested in answers to a couple of questions.
1. UML2 claims several advantages however I can still see the same problem of gigantic diagrams and adhoc design patterns being formed to suit implementation do you agree?
2. UML2 modelling porbably wont' be used by smaller teams of developers. So is it relavant to argue that modelling techniques need to be scalable to the problem size and the team's man power. If so please suggest alternatives?
3. I have been informed that there can be quite some confusion between Asynchronous and Synchronous modelling in UML2 is this true or am I confused?
4. What about other "silver bullets" e.g design by contract of AOP(Aspect Orientated Programming) we have already spawn modelling concepts based on these approaches. How do you think they compare?
Kind regards
Prashant

In mathematics it is fairly widely accepted that there are two different type of mathematician, namely "geometers" and "algebrists". The presumed difference is between those who prefer to rely on their visual cortex for thinking - they "see" the problems and those who prefer to rely on their audio/language cortex and are pushing words around to solve their problems.
Some problems are easier to work in one mode and others are easier in the other mode. All working mathematicians, understand both methods, they just in general prefer one method over the other. Like being right handed or left handed.
My view of flowcharts and their modern UML equivalent is that they are just a way of presenting the design problem in different ways to the brain. They are ways of attempting to recruit different brain tissue to work on the problem.
This model of how people think, explains all the facts that I am aware of, namely that some people love UML, some people hate UML, some projects are helped by UML and some are hindered.
A complicated diagram with lines runing all over it is just the graphical equivalent of spaghetti code and just about as useful and easy to maintain. You have done something wrong. Just like it is easy to say that if you have a rountine with thousands of lines in one method it is certainly wrong.
As a mathematician I am most certainly a geometer, as a programmer, probably largly by training, I am an algebrist. I see math, I hear programs.
I have sympathy with those who say that you must learn this or that technique, because any technique that you can learn will enlarge the set of problems that you can solve elegantly. On the other hand I am extremely skeptical of ony one who claims that any particular technique is absolutely necessary for solving any problems.
For everyone that swears that UML is the only way to do design I can no doubt find someone that runs a UML emitter over their code when they are finished with a project so that they can satisfy some "requirement" that they produce UML design documents. Neither party is "right." Left handed people are not broken versions of right handed people.
I think it is foolishness to claim that one tool works for all things at all times. I likewise think it is foolishness to shun a possibly useful tool just because it is not the way your brain likes to work. Fix your brain. Exercise it.
As for what you will find people actually using in industrial settings, well Horatio, there are more things than ever dreamed of in your philosophies.
Is UML2 worth learning. Absolutely. Soak it up and then forget it. Try not to lose any sleep.

Is it worth learning JAVA?

Howdy!
Is it worth learning JAVA or would I be oaky with just sticking with ABAP and learning ABAP objects?
All opinions welcome y'all!

Hi Steve,
Sticking to ABAP is for the (near) future an option.
However SAP is migating to the SAP NetWeaver environment where a totally new development suite is presented: The SAP NetWeaver Development Studio.
With it you can develop the new Web Dynpro's and the studio is based on IBM's Eclipse (totally Java).
You can develop without knowledge of Java, however some knowledge of Java is very helpfull.
If you want to stick to ABAP: Somewhere half/end of the year 2005 this Developer studio will also be expanded with ABAP (you have to wait for that).
On the other hand, current releases of SAP components (Like CRM, Enterprise, SCM, APO and so on) still require the knowledge of ABAP (preferably ABAP Objects).
In my view ABAP Objects will play a major role in the new Developer Studio (when it comes available). Straight forward ABAP (without OO parts) will see it's role slowly getting less and less.
So my advice would be: Learn Java (at least do a beginners training with it) and learn all about ABAP Objects. You will be ready for the future.
Regrads,
Rob.

Wordpress - as a website developer, is it worth learning?

I've always made websites with Dreamweaver using HTML, CSS, and Jquery. If the client wanted a CMS, I used CushyCMS or Pagelime. I haven't done an eCommerce website, but if I was called upon to do one, I guess I would have installed Shopify or something similar.
I've been thinking I should learn how to create custom websites for my clients powered with Wordpress. My reasoning for that was that it provides a free CMS and shopping cart solution for them, plus who knows what other goodies are available?? I imagine a plethora of fabulous stuff that I can put on their websites very easily, like discussion forum pages and opt-in newsletter buttons and other magic widget thingies.
I have a new client who has specifically requested a Wordpress site, so now seems to be the time to learn. However, having spent a whole day already trying to get my head around Wordpress, and reading a few comments on the forums here, I've realised it's actually not that easy! Certainly not the magic carpet ride it says it is! I think it'll be quite a learning curve for the client, and maybe Cushy is a better option for clients who just want a simple CMS for their business website.
What do others on the forum think? Is it worth a developer going to the effort to learn Wordpress? Is there any advantage to my clients? Does it have a free shopping cart solution?

Yes it's worth at least investigation Wordpress. No, it's not that easy to get your head around.
What you have to do is determine what it is you want your client to have the ability to do. Personally I can't see a reason to give a client FULL CMS control of a website because they will create a train wreck in only a few days. No CMS is a subsitute for a professional web developer.
What I'm leaning towards is implementing Wordpress into sites of say 20-30 pages or less, where specific area/pages of the site can be updated by the client. Anything bigger then its my opinion that the company probably needs help updating the site and should employ a professional to do so.
You don't need to take onboard the FULL capabilities of Wordpress just isolate the bits that fit in with YOUR workflow NOT Wordpresses workflow.
With this in mind my approach (at the moment) is to build a site as normal in Dreamweaver and then integrate Wordpress into it so I have control rather than what is the normal procedure where Wordpress takes control and you have to jump through hoops manipulating other peoples themes and css files.
Many Wordpress tutorial you'll find on the net are outdated or assume you know more than you do about Wordpress and leave you 'hanging'
After Googling around I found what I believe to be one which is fairly easy to follow and shows you how to turn a static html website into a Wordpress CMS website.
http://www.youtube.com/watch?v=1o2XcHqQbRY&list=UU0f9NbKjUUbnL2cOa12ENIQ&index=81&feature= plcp
The tutorial above is very basic BUT very understandable, you have to then build on it to take advantage of more Wordpress features like adding new editable 'content blocks' and 'global post areas'.
Wordpress in its original form is very powerful but rather complex to understand as the pages are made up from compiling a number of other files into one page. If you have been used to building in Dreamweaver then this will most likey NOT be a comfortable workflow for you. The video link above shows you how to avoid this and yet still get some CMS fetaures into your site.
Personally I think Wordpress 'out of the box' is either for amateurs or those who are extremely advanced in html,css and php. Those inbetween are well advised to sift through Wordpress and disregard the bits that will cause issues. Take for instance the automated menu system. May sound good but what happens when your client adds more menu buttons to your carefully crafted horizontal menu bar. Depending on the space it could we'll break it very very easily. So you need to know what bits of Wordpress to include and what bits not to.

InDesign ExtendScript...is this worth learning?

Hello,
I have been trying to learn AppleScripting so that I might automate more of my of my InDesign stuff. When searching for more books, I came across a book by Shirley W.Hopkins called automating Adobe InDesign CS4 with ExtendScript. Does this scripting option seem to be a good one to learn, even over AppleScripting? It seems like a valuable option if I want to focus on InDesign, but I would like to hear from others if they are using it and is it worth the learning curve?
thanks!!

It seems like someone could simply write a JavaScript API/interpreter that interfaced with AppleScript. Then JavaScript would work on a Mac for other apps, too.
Someone did, several years ago; it was in Script Debugger. It's since been abandoned due to overwhelming lack of interest.
Cool. I'll look it up. Thanks.
If Apple were as committed to open standards as they claim, we'd already have JS that could automate a Mac.
The only claimed commitment was to "open Web standards", which has nothing to do with IAC languages like AppleScript. And if they did implement js scripting at a system level, it would of necessity be different to Adobe's custom implementation (running outside an app's environment raises a whole lot of other issues). So people would have a choice of two flavors of js, instead of js and something else -- that seems like a retrograde step to me (and would make life around here really interesting).
I was being partially facetious on this point. Just poking a little fun at the Apple worship (I'm a Mac user as well, but for lack of a better alternative).
My opinion as someone who codes quite a bit, is that terseness is a preferred quality in a computer language.
And many people who code quite a bit would probably agree with you. (Whether that's because that's how they learned to code is another question.) But the point of using a natural-language like interface for AppleScript was to make it accessible to those who don't necessarily "code quite a bit". One size doesn't suit all.
Actually, I was a designer before I was a developer (and I still am a designer). I work almost entirely with designers (and not other developers). So I have a reasonably balanced perspective on this. The idea of a "natural-language" is a bit bogus. Especially because programming is about logic, so "natural" should reflect an ease of writing logical statements. You still have to learn an entirely arbitrary language with Applescript (especially arbitrary in English, which is loaded with synonyms, so you can't guess keywords), it's just more verbose. And it still has to write logical statements. Something that is truly oriented to a non-coder, omits code entirely (e.g., Automator).
I'm not suggesting one-size fits all, I'm all for different languages for different purposes...if I can state it a bit hyberbolically...just that a tissue box does not make a great shoe, though it may cover your foot.

Worth learning Score Editor for printout or 3rd party software bettereasie?

Hi,
I can either start seriously checking out the Score Editor for lead sheets and more involved printing of music... or get Sibelius or Finale and use those. I am not familiar with any of these - as I haven't started printing out music - but feel it's time.
I'd prefer just to stay in my all in one Logic Studio - but not sure if it's worth it in the big picture. (as in - if 3rd party software is easier/better by far - and most Logic people use those - why waste the time learning Score Editor in Logic?).
Any of you use the Score Editor for printing out scores, lead sheets? Whatdya think?
Thanks in advance.

It depends on the music genre you want to score for....
But, it's not a waste of time because it's another way for editing...but it really depends. I use sibelius but I still use the score editor in Logic, not for printing but I use it, a lot.

Is the Gaia framework worth learning?

I've been learning greensock and I find it helpful now when studying greensock I've been introduced to Gaia does anyone here have an opinion on Gaia?

I have never used it before, but just gone to look at it. I am not a good flash developer yet, but I do know java extremely well, and if someone asked me if a similar library was good to learn with the java language, I would have mixed opinions. If the person asking me was new to the language, and did not know a lot, I would say stay away from it. In java, I tend to call them sort of libraries "lazy developer libraries", meaning that the people who use them are too lazy to actually learn the language, and would much rather use a library which does most of the work for them. I mean looking at the features Gaia provides, it is nothing which cant be done directly with as3, without any use of that library.
However, if an experienced developer asked me the same question (like yourself for instance), then I would suggest that using it could be of great benefit, especially if your expected to deliver projects in a relatively quick time. Reason I say it is ok to use for experienced developers is because they understand how to do everything the package provides them with manually, and using the package will not interfer with their learning. It has actually got me interested in it, especially when I saw you could create websites in under 10 minutes. However, I will try to stay away from it until I get better with AS3

Bash still worth learning?

Today I needed to write a script that would copy a few of my dot files into a git repository. I cracked vim open and began to experiment with rudimentary bash constructs, but after a while gave up and decided to write the thing in Python, just because Python is simple and I know it.
Are there any good reasons as to why I should pursue a knowledge of bash with other, higher level languages around (e.g. Python) when bash's breadth of use is (relatively) limited?

Kiwi wrote:So what Xyne is saying is that Python sucks more than Bash? Unless, I suppose, if that is a vacuum made by Microsoft.
Heh. Oh the flame wars!
Cyrusm wrote:I say if you're comfortable with python, and it does what you need it to do, then use python. There is no real "need" to learn Bash imo. personally I like bash for quick and dirty scripts, python for more elaborate scripts. but really it's just what ever you're happy using.
Exactly my thoughts... If you can achieve the same thing 2 different ways and the result is the same, then do whatever is more comfortable/easier for you.
Although, if you'll excuse this little anecdote..... I used to *hate* perl, with a passion. I'd go out of my way to avoid it, because I didn't know it and when I tried to use it I found it esoteric and painful. Over the last few months though I had managed to get a (basic) grasp of perl, and now I love it. It can make things so much easier than doing the same in bash. The reverse is also true.
Moral of my anecdote (I think): Right Tool for the Right Job. The more tools you have (know), the easier to find a suitable tool for your task.

Is java worth learning for game developement?

Please dont take this as an insult to the java language, im having a blast learning this language and love it more than any other that i have learned so far.
I just have one creeping issue, ive heard that the game development aspect of java isnt quite there yet, and is quite "slow".
so id just like to ask. Is it possible to write a good 3d game using java(simple FPS or RPG) using java? what is its limitations when it comes to programming games?(is it just slower? does it have the same potential in creating games like python does?)
thanks if you can answer these questions for me!

"Serious" game development has been pretty much C++'s domain for ages.
However you have things like Minecraft, which is done in Java and racked up a few million for the author. Then you have Android game development, which is pretty much Java...

Is Javascript worth learning?

Is there significant learning curve to master Javascript if you know Java reasonably well? And is there much of any point to learning Javascript? Don't Java servelets largely eliminate the need for Javascript?

I would say that there is a reasonably significant learning curve even if you know java already as they have similar syntax but some very different concepts.
servlets are of course server side wheras JavaScript is client side. If you don't mind going back to the server everytime your application does something then stick with servlets otherwise give Javascript a try.
Javascript can always be switched off by the user don't forget.

Learn JSTL

Hi,
I used to have scriptlet in jsp page and normally use System.out.println to debug any jsp problems. Now I want to change them to use JSTL. Following I am trying to output all options and make one of selected:
      <% if(myBean.getOptions() != null) {
                  List list = myBean.getOptions();
                  for (int i=0; i < list.size(); i++) {
                       HashMap map = (HashMap)list.get(i);
                       String id = (String)map.get("id");
                       String description = (String)map.get("name");
      %>
      <option value="<%= id %>" <%= MiscUtil.optionSelected(id, myBean.getBookId())%>> <%= description %></option>
      <% } } %>I made it as:
<c:if test="${myBean.options}">
     <c:forEach var="item" items="#{myBean.options.items}">
          <c:set var="id" value="${item.value.id}"/>
          <c:set var="description" value="${item.value.name}"/>
      <option value="${ id }" <c:out value="DON'T KNOW HOW TO DO THIS"/>> ${ description }</option>
      </c:forEach>
</c:if>It shows empty list and don't know how to do default "select" in option. Maybe it's quite obviously wrong but can't really figure it out. How can I debug this? Thanks

Let me see if I understand your datastructures here:
You have a List that you iterate through
Each entry in the list is a map
The map has in it keys "id" and "value" which you want to display in the dropdown box.
The MiscUtil call looks to be a static method. My guess is that it wil return "selected" if the id is the same as myBean.getBookId()?
Lets take these one at a time:
First the forEach loop, the 'items' attribute should be your list (myBean.getOptions()) which translates to ${myBean.options}
Each 'item" will then be a Map.
map.get("id") can be written as ${map['id']} or just ${map.id}
similar for map.get("name");
This leads to the following code for rendering the dropdown list:
<c:forEach var="mapItem" items="${myBean.options}">
<c:set var="id" value="${mapItem.id}"/>
<c:set var="description" value="${mapItem.name}"/>
<option value="${id}" >${description}</option>
</c:forEach>Next: the selected value.
There are two ways you could do this
1 - in JSTL with an if statement
<c:if test="${id == myBean.bookId}"> selected </c:if>2 - use a JSTL custom function tag to wrap the call to MiscUtil
In a tld file:
<taglib>
<function>
<name>optionSelected</name>
<function-class>com.mypackage.MiscUtil</function-class>
<function-signature>
      java.lang.String optionSelected(java.lang.String, java.lang.String)
</function-signature>
</function>
</taglib>You would then import that tld into your jsp page (much like you do the JSTL)
Something like:
<%@ taglib prefix="misc" uri="http://MyMiscUtil"%>
and invoke it via
${misc:optionSelected(id, myBean.bookId}
The final thing:
<c:forEach var="mapItem" items="${myBean.options}">
<c:set var="id" value="${mapItem.id}"/>
<c:set var="description" value="${mapItem.name}"/>
<option value="${id}" <c:if test="${id == myBean.bookId}"> selected </c:if>>${description}</option>
</c:forEach>Cheers,
evnafets
Edit: The forum is not displaying my last code example directly. It has added an extra > character between the value="${id} and the <c:if>
I can't seem to stop it doing that, so just be careful about copying/pasting that code ;-)
Or even better, reply and then select "quote original"
That will return you an undoctored version.

Learning curve / path from Go Live! to Dreamweaver; is it worth it?

Learning curve / path from Go Live! to Dreamweaver; is it worth it?

I'll be blunt, it's not worth "learning Dreamweaver" at all, if you don't understand html, css and basic javascripting prior to opening the program.
Without those three things, DW becomes a monstrous time sink that allows you to produce rudimentary websites that your viewers and peers will scoff at.
Now, if you do understand HTML and CSS (and to a lesser extent, javascript) running the DW tutorials from the Adobe site (hit F1 while in DW to open the Help site) will help you get up and running in no time and you'll be able to create some fairly advanced sites relatively quickly with current internet standards-compliant code.
If you don't understand code and refuse to educate yourself, as Ben says, Muse would be the way to go.

How to learn UCM 11g from scratch

From where should I learn UCM 11g I am new to this product.WebCenter Content

Hemant,
You will need a test system, use VirtualBox as you can undo any disasters by taking snapshots. If you don't know how to configure and administer managed servers in Weblogic Server then learn that first - just how to configure UCM and Node Manager so you can start and stop it from the Admin Server console.
It is worth learning to install Webcenter Content on Linux ( I recommend Oracle 6.6) and also on Windows if you want to use Enterprise Capture with Recognition but if you are impatient to start with UCM, Oracle have a ready-made VM with just about everything you need installed. Oracle WebCenter Portal 11.1.1.8 Virtual Machine | Oracle Technology Network | Oracle. You may need to patch the installation, I don't know what patch level it is set to.
When reading the Oracle documentation Make sure you get the WCC UCM documentation not the IPM documentation. Make lots of bookmarks and when you see "for more information on..." open the link in a new tab or you will get lost seven levels down when you realise you are back to the same page you started from.
Learn the security model, a group in Weblogic Server with the same names as a Role in UCM will be granted the Role's access, how to use content types, rules and profiles. if you have experience with any other DM systems, know that metadata fields in UCM are not attributes of a document class, they are attributes of the system and present for all documents unless you filter them out with Rules.
Know also that there are two Web UIs so when you read the latest documentation the screenshots are from the latest Web UI. I don't know if it has been installed in the Portal VM but if you want to install it, read the Support article 1618305.1, it is not simple.

My question about JSTL

First, sorry for not being a native English speaker.
I started to learn JSTL for Web application a few days ago.
Now I try to create a toy web app just to see how to use those JSTL tags.
I created a simple web page as following:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
    <body>
        <c:if test="${personlist==null}">
            AAA
        </c:if>
        <c:if test="${personlist!=null}">
            BBB
        </c:if>
    </body>
</html>During the above, the personlist is the name of a object which I have not created. In my opinion, I think there should always one output when openning the page in the browser no matter the object personlist exists or not, but in fact, I was wrong, the fact is nothing displays on the screen. I don't know what's wrong. If you could give me some clue, it should be appreciated. Thank you.

Hi your are right ,you should see AAA on your web page.
I try it and your code is good ,i got it AAA on my web page you taglib is
correct but it wont work if you don't put JSTL library in your project.
So you must also add the JSTL library to the project.
Find your JSTL 1.1 library and put it to your project.
Try it!

Is it worth learning JSTL?
