• Exam 70-541 - TS: Microsoft Windows SharePoint Services 3.0 - Application Development

  - by DigiMortal

  Today I passed Microsoft exam 70-541: Microsoft Windows SharePoint Services 3.0 - Application Development. This exam gives you MCTS certificate. In this posting I will talk about the exam and also give some suggestions about books to read when preparing for exam. About exam This exam was good one I think. The questions were not hard and also not too easy. Just enough to make sure you really know what you do when working with SharePoint. Or at least to make sure you how things work. After couple of years active SharePoint coding this exam needs no additional preparation. The questions covered very different topics like alerts, features, web parts, site definitions, event receivers, workflows, web services and deployments. There are 59 questions in the exam (this information is available in internet) and you have time a little bit more than two hours. It took me about 40 minutes to get questions answered and reviewed. I strongly suggest you to study the parts of WSS 3.0 you don’t know yet and write some code to find out how to use these things through SharePoint API. Good reading For guys with less experience there are some good books to suggest. Take one or both of these books because there are no official study materials or training kits available for this exam. One of my colleagues who is less experienced than me suggested Inside Microsoft Windows SharePoint Services 3.0 by Ted Pattison and Daniel Larson. He told me that he found this book most useful for him to pass this exam.   When I started with SharePoint Services 3.0 my first book was Developer’s Guide To The Windows SharePoint Services v3 Platform by Todd C. Bleeker. It helped me getting started and later it was my main handbook for some time. Of course, there are many other good books and I suggest you to take what you find. Of course, before buying something I suggest you to discuss with guys who have read the book before. And make sure you mention that you are preparing for exam.   Conclusion If you are experienced SharePoint developer then this exam needs no preparation. Okay, some preparation is always good but if you don’t have time you are still able to pass this exam. If you are not experienced SharePoint developer then study before taking this exam – it is not easy stuff for novices. But if you pass this exam you can proudly say – yes, I know something about SharePoint! :)

• Installing Forms and Reports on a development system

  - by Duncan Mills

  By popular demand I've resurrected / updated one of the old blog postings from Jan Carlin's Blog on GroundSide here. A recent (lengthy) post on the Forms forums chronicles the problems some of you have had installing F&R on a development machine. See the link in the headline of this post for the main one. When installing, here are some points to bear in mind: Download and install Weblogic Server first. http://www.oracle.com/technology/software/products/middleware/index.htmlFind the Forms and Reports (and Disco and Portal) zip files here. Download them to the desktop (or some other temporary directory of your choosing). Unzip both of the two zip files into the same new directory (maybe called 'stage') and check that you have 4 directories in the stage dir when you are finished unzipping: 'Disk1', 'Disk2', 'Disk3' and 'Disk4'. These folders are specified in the zip file structure and must be preserved for the setup executable to work. If you use WinZip and have a right click menu option that say "Extract to here", use that by right click-dragging the zip file onto the newly created directory. Don't use the "Extract to folder %HOME%\Desktop\ofm_pfrd...disk_1of2" option. That will get you into the trouble that was reported early in this thread. Free up as much memory as you can. Stop services and background processes and virus scanners and databases (you don't need a DB to install Forms) and other things lurking about on your machine. You can restart them when the install is done. Around 1.5 GB free real memory should do it. If it doesn't, free up more if you can. Don't change the swap space unless you know what you are doing. Let Windows handle it. A 1 GB machine will likely not be enough. You will likely need at least 2GB of RAM.Start the install with setup.exe from the 'Disk1' directoryChoose the Install and Configure option unless you have a good reason not to.Choose a unique instance name even if you deinstalled and removed the last install. I suggest using 'asinst_20090722_1' (today's date in ISO format with a running incremented number at the end if you install more than two times on a particular day).Unselect Portal and Discoverer and select the Builders you want.Unselect WebCacheUnselect OHS.Unselect the single sign-on option Check for any failures and choose the retry option if any occur. If that doesn't fix the problem, call Oracle Customer Support .

• What is a resonable workflow for designing webapps?

  - by Evan Plaice

  It has been a while since I have done any substantial web development and I'd like to take advantage of the latest practices but I'm struggling to visualize the workflow to incorporate everything. Here's what I'm looking to use: CakePHP framework jsmin (JavaScript Minify) SASS (Synctactically Awesome StyleSheets) Git CakePHP: Pretty self explanatory, make modifications and update the source. jsmin: When you modify a script, do you manually run jsmin to output the new minified code, or would it be better to run a pre-commit hook that automatically generates jsmin outputs of javascript files that have changed. Assume that I have no knowledge of implementing commit hooks. SASS: I really like what SASS has to offer but I'm also aware that SASS code isn't supported by browsers by default so, at some point, the SASS code needs to be transformed to normal CSS. At what point in the workflow is this done. Git I'm terrified to admit it but, the last time I did any substantial web development, I didn't use SCM source control (IE, I did use source control but it consisted of a very detailed change log with backups). I have since had plenty of experience using Git (as well as mercurial and SVN) for desktop development but I'm wondering how to best implement it for web development). Is it common practice to implement a remote repository on the web host so I can push the changes directly to the production server, or is there some cross platform (windows/linux) tool that makes it easy to upload only changed files to the production server. Are there web hosting companies that make it eas to implement a remote repository, do I need SSH access, etc... I know how to accomplish this on my own testing server with a remote repository with a separate remote tracking branch already but I've never done it on a remote production web hosting server before so I'm not aware of the options yet. Extra: I was considering implementing a javascript framework where separate javascript files used on a page are compiled into a single file for each page on the production server to limit the number of file downloads needed per page. Does something like this already exist? Is there already an open source project out in the wild that implements something similar that I could use and contribute to? Considering how paranoid web devs are about performance (and the fact that the number of file requests on a website is a big hit to performance) I'm guessing that there is some wizard hacker on the net who has already addressed this issue.

• Is it a bug or a task when something doesn't work, yet, in development process

  - by Patkos Csaba

  We usually have this dilemma in our team. Sometimes, in order to implement a task or a story we find out that the system must be in a specific state. For example, a specific system configuration has to be made beforehand. The task / story can be completed and it is working as specified on it with the proper configuration in place. Note that the configuration is not directly related with the task. Next, we have to create a new ... ??? ... something for the process of generating that configuration file. This is where the problems appear. Some say that it is a bug others say it is a task or an extra feature. So, where is the limit between bugs and tasks in the development phase? Should we even consider something a bug if all the tasks are working as stated in their definitions? Can a thing be considered a bug because one compares it to the current (unstable) state of the system? Short example: A feature requires configuring a communication service for a specific operation. In the process of the implementation the team discovers that the service requires the hostnames of the pears to be resolvable to an IP address. The team adds the hostnames to the DNS server (or hosts files) and continues implementing the required feature. After the initial feature is working, a question is risen. Should the sysadmin configure the DNS or hosts file or should our application do it automatically? An automatic solution is possible. So a decision is made to implement it. ... here start the discussions ... is this a bug or an extra feature / task? PS: I know that I mixed feature / task / story in the question. It is intentional. I am interested in separating bugs from the rest. Doesn't matter what the rest means in a particular case.

• Introducing Agile development after traditional project inception

  - by Riggy

  About a year and a half ago, I entered a workplace that claimed to do Agile development. What I learned was that this place has adopted several agile practices (such as daily standups, sprint plannings and sprint reviews) but none of the principles (just in time / just good enough mentality, exposing failure early, rich communication). I've now been tasked with making the team more agile and I've been assured that I have complete buy-in from the devs and the business team. As a pilot program, they've given me a project that just completed 15 months of requirements gathering, has a 110 page Analysis & Design document (to be considered as "written in stone"), and where I have no access to the end users (only to the committee made up of the users' managers who won't actually be using the product). I started small, giving them a list of expected deliverables for the first 5 sprints (leaving the future sprints undefined), a list of goals for the first sprint, and I dissected the A&D doc to get enough user stories to meet the first sprint's goals. Since then, they've asked why we don't have all the requirements for all the sprints, why I haven't started working on stuff for the third sprint (which they consider more important but is based off of the deliverables of the first 2 sprints) and are pressing for even more documentation that my entire IT team considers busy-work or un-related to us (such as writing the user manual up-front, documenting all the data fields from all the sprints up front, and more "up-front" work). This has been pretty rough for me as a new project manager, but there are improvements I have effectively implemented such as scrumban for story management, pair programming, and having the business give us customer acceptance tests up front (as part of the requirements documentation). So my questions are: What can I do to more effectively introduce change to a resistant business? Are there other practices that I can introduce on the IT side to help show the business the benefits of agile? The burden of documentation is strangling us - the business still sees it as a risk management strategy instead of as a risk. What can we do to alleviate their documentation concerns and demands (specifically the quantity of documentation and their need for all of it up front)? We are in a separate building from our business, about 3 blocks away and they refuse to have their people on the project co-habitate b/c that person "won't be able to work on their other projects while they're at our building." They expect us to always go over there and to bundle our questions so that we can ask them all at once and not waste that person's time with "constant interruptions." What can we do to get richer communication from them? Any additional advice would also be appreciated. Thanks!

• Finding a new programming language for web development?

  - by Xeoncross

  I'm wondering if there are any un-biased resources that give good, specific overviews of programming languages and their intended goals. I would like to learn a new language, but visiting the sites of each language isn't working. Each one talks about how great it is without much mention of it's weaknesses or specific goals. Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. Python is a programming language that lets you work more quickly and integrate your systems more effectively. Having been a PHP developer for years, Vic Cherubini sums up my plight well: I knew PHP well, had my own framework, and could work quickly to get something up and running. I programmed like this throughout the MVC revolution. I got better and better jobs (read: better paying, better title) as a PHP developer, but all along the way realizing that the code I wrote on my own time was great, and the code I worked with at work was horrible. Like, worse than horrible. Atrocious. OS Commerce level bad. Having side projects kept me sane, because the code I worked with at work made me miserable. This is why I'm retiring from PHP for my side projects and new programming ventures. I'm spent with PHP. Exhausted, if you will. I've reached a level where I think I'm at the top with it as a language and if I don't move on to a new language soon, I'll be done completely with programming and I do not want that. Languages I've looked at include JavaScript (for node.js), Ruby, Python, & Erlang. I've even thought about Scala or C++. The problem is figuring out which ones are built to handle my needs the best. So where can I go to skip the hype and get real information about the maturity of a platform, the size of the community, and the strengths & weaknesses of that language. If I know these then picking a language to continue my web development should be easy.

• My 2011 Professional Development Goals

  - by kerry

  I thought it might be a good idea to post some professional goals for 2011.  Hopefully, I can look at this list at the end of the year and have accomplished most of them. Release an Android app to the marketplace – I figured I would put this first because I have one that I have been working on for a while and it is about ready.  Along with this, I would like to start another one and continue to develop my Android skills. Contribute free software to the community – Again, I have an SMF plugin that will fill this requirement nicely.  Just need to give it some polish and release it.  That’s not all, I would like to add a few more libraries on github, or possibly contribute to an open source project. Regularly attend a user group meetings outside of Java – A great way to meet people and learn new things. Obtain the Oracle Certified Web Developer Certification – I got the SCJP a few years ago and would like to obtain another one.  One step closer to Certified Enterprise Architect. Learn scala – As a language geek, I like to stick to the Pragmatic Programmer’s ‘learn a new language every year’ rule (last year was Ruby).  Scala presents some new concepts all wrapped in a JVM-based OOP language.  Time to dig in. Write an app using JSF – New JEE 6 features are pretty slick.  I want to really leverage them in an app. Present at a user group meeting – Last but not least, I would like to improve my public speaking and skills in presenting.  Also, is a great reason to dig in to some latest and greatest tech. Use git more, and more effectively – Trying to move all my personal projects from Subversion to Git. That’s it.  A little daunting, but I am confident I can at least touch on most of these and it’s a great roadmap to my professional development.

• Is a startup revolving around a web app still viable?

  - by NRUTA

  I have an idea for a startup that revolves around a web app. I plan to incorporate a mobile app in the future but, unlike something like instagram, users will be more likely to access with a desktop computer. I am learning Ruby On Rails currently but wonder if, starting in the 4th quarter of 2012, I am focusing on a technology (web development) that is becoming obsolete. Should I dump the idea for something that revolves around mobile technologies and spend my time learning something like iOS development instead?

• Series On Embedded Development (Part 2) - Build-Time Optionality

  - by user12612705

  In this entry on embedded development, I'm going to discuss build-time optionality (BTO). BTO is the ability to subset your software at build-time so you only use what is needed. BTO typically pertains more to software providers rather then developers of final products. For example, software providers ship source products, frameworks or platforms which are used by developers to build other products. If you provide a source product, you probably don't have to do anything to support BTO as the developers using your source will only use the source they need to build their product. If you provide a framework, then there are some things you can do to support BTO. Say you provide a Java framework which supports audio and video. If you provide this framework in a single JAR, then developers who only want audio are forced to ship their product with the video portion of your framework even though they aren't using it. In this case, support providing the framework in separate JARs...break the framework into an audio JAR and a video JAR and let the users of your framework decide which JARs to include in their product. Sometimes this is as simple as packaging, but if, for example, the video functionality is dependent on the audio functionality, it may require coding work to cleanly separate the two. BTO can also work at install-time, and this is sometimes overlooked. Let's say your building a phone application which can use Near Field Communications (NFC) if it's available on the phone, but it doesn't require NFC to work. Typically you'd write one app for all phones (saving you time)...both those that have NFC and those that don't, and just use NFC if it's there. However, for better efficiency, you can detect at install-time if the phone supports NFC and not install the NFC portion of your app if the phone doesn't support NFC. This requires that you write the app so it can run without the optional NFC code and that you write your install app so it can detect NFC and do the right thing at install-time. Supporting install-time optionality will save persistent footprint on the phone, something your customers will appreciate, your app "neighbors" will appreciate, and that you'll appreciate when they save static footprint for you. In the next article, I'll talk about runtime optionality.

• Maven WTP webapp with maven-eclipse-plugin but without m2eclipse

  - by chrsk

  I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't want to use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration?

• How to throttle login attemps in Java webapp?

  - by Jörn Zaefferer

  I want to implement an efficient mechanism to throttle login attemps in my Java web application, to prevent brute-force attacks on user accounts. Jeff explained the why, but not the how. Simon Willison showed an implementation in Python for Django: That doesn't really help me along as I can't use memcached nor Django. Porting his ideas from scratch doesn't seem like a great either - I don't want to reinvent the wheel. I found one Java implementation, though it seems rather naiive: Instead of a LRU cache, it just clears all entries after 15 minutes. EHCache could be an alternative for memcached, but I don't have any experience with it and don't really want to intoduce yet another technology if there are better alternatives for this task. So, whats a good way to implement login throttling in Java?

• When is a webapp called Beta, alpha, pre-alpha, or none

  - by dmontain

  I've come across many apps on the web that call themselves Beta. I've come across other apps that had an alpha designation. I've even come across some that called themselves pre-alpha, whatever that means (if you know please clarify). Then I've come across some really bad webapps that shouldn't have left the developer's computer and they didn't have any beta designations. I've also seen some well built apps that called themselves Beta, including Stack Exchange (the mother site of SO) which I believe is very full featured to be called a Beta. I'm a little confused. It seems people are doing it at their whims. Is there an established rule or a checklist that can help decide what stage an app is in (beta, alpha, pre-alpha, or none)? P.S. Please feel free to retag as appropriate.

• What web-development platform should I use considering Time-To-Market?

  - by Jonas

  I have been looking at a few differend platforms for my coming web-development project. I would like to hear what web-development platform is recommended when considering Time-To-Maket. Suppose that I already know the programming language well, but not the web-framework. The OS will be Linux. My requirements and priorities: Time-To-Market RESTful Maintainable code Scales-up (not dog-slow) The one I have looked at but never used are: Java and Play! Framework or GWT Python and Django PHP and Zend Framework Ruby and Ruby on Rails Erlang and Nitrogen and Webmachine Scala and Lift C++ and Wt C# and ASP.NET Mono It's a bonus if the framework has support for making sites for mobile phones.

• Random blank pages on Safari when developing webapp

  - by Ali

  Hey guys, I've been experiencing a safari problem while building a web application. The screen goes completely blank (white) and refreshing won't help. Going to another page on the site gives the same problem. Then magically, after a little while, everything goes back to normal and pages are rendered correctly! This started happening around the same time that I SUSPECT my hosting automatically upgraded from PHP 5.2.x to 5.3 (all of a sudden, we got 'deprecated function' errors and the error settings and handling were unchanged) I also have to mention that this doesn't happen in our dev environment (PHP 5.2.9, Apache 2) Settings Safari 4.0.2 and the latest one (don't know the version) Server side: PHP 5.3, MySQL 5.0.90, Apache is cPanel Easy Apache v3.2.0 Does anyone know why this is happening at all, or how to fix it? I appreciate any help or pointers you might have. Thanks!

• Restart IIS7 webapp for debug in VS2008

  - by spender

  I'm developing an ASP.NET asyc generic handler which uses a static System.Threading.Timer instance to feed data to the response output stream while the context is in the asynchronous phase. I'm having issues at startup that I'd like to debug. Currently, because of the long-lived nature of the timer, I'm manually killing w3wp.exe in order to cause the application to restart. I'm aware that there are other ways to do this, but this is the best workflow I can find! Isn't there a way to force a cold start when I hit f5, instead of the standard VS approach of attaching to the existing IIS process?
