• WebCenter .NET Accelerator - Microsoft SharePoint Data via WSRP

  - by john.brunswick

  Platforms in the enterprise will never be homogeneous. As much as any vendor would enjoy having their single development or application technology be exclusively adopted by customers, too much legacy, time, education, innovation and vertical business needs exist to make using a single platform practical. JAVA and .NET are the two industry application platform heavyweights and more often than not, business users are leveraging various systems in their day to day activities that incorporate applications developed on top of both platforms. BEA Systems acquired Plumtree Software to complete their "liquid" view of data, stressing that regardless of a particular source system heterogeneous data could interoperate at not only through layers that allowed for data aggregation, but also at the "glass" or UI layer. The technical components that allowed the integration at the glass thrive today at Oracle, helping WebCenter to provide a rich composite application framework. Oracle Ensemble and the Oracle .NET Application Accelerator allow WebCenter to consume and interact with the UI layers provided by .NET applications and a series of other technologies. The beauty of the .NET accelerator is that it can consume any .NET application and act as a Web Services for Remote Portlets (WSRP) producer. I recently had a chance to leverage the .NET accelerator to expose a ASP .NET 2.0 (C#) application in the WebCenter UI (pictured above) and wanted to share a few tips to help others get started with similar integrations. I was using two virtual machines for the exercise - one with Windows Server 2003, running SharePoint and the other running WebCenter Spaces 11g. For my sample application data I ended up using SharePoint 2007 lists and calendars (MOSS 2007) to supply results using a .NET API for SharePoint.

• How to achieve a loosely coupled REST API but with a defined and well understood contract?

  - by BestPractices

  I am new to REST and am struggling to understand how one would properly design a REST system to both allow for loose coupling but at the same time allow a consumer of a REST API to understand the API. If, in my client code, I issue a GET request for a resource and get back XML, how do I know what to do with that xml? e.g. if it contains <fname>John</fname><lname>Smith</lname> how do I know that these refer to the concept of "first name", "last name"? Is it up to the person writing the REST API to define in documentation some place what each of the XML fields mean? What if producer of the API wants to change the implementation to be <firstname> instead of <fname>? How do they do this and notify their consumers that this change occurred? Or do the consumers just encounter the error and then look at the payload and figure out on their own that it changed? I've read in REST in Practice that using a WADL tool to create a client implementation based on the WADL (and hide the fact that you're doing a distributed call) is an "anti-pattern". But I was planning to do this-- at least then I would have a statically typed API call that, if it changed, I would know at compile time and not at run time. Why is this a bad thing to generate client code based on a WADL? And how do I know what to do with the links that returned in the response of a POST to a REST API? What defines this contract and gives true meaning to what each link will do? Please help! I dont understand how to go from statically-typed or even SOAP/RPC to REST!

• What You Said: Where Do You Find Your Next Game?

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite places and tricks for finding new video games to play. It turns out the least of your problems was finding new games! From the comments it became apparent How-To Geek readers had absolutely no problem finding new games to add to their gaming stable. Buzz writes: I have quite an elaborate procedure in finding my next game:For free games i simply follow the feeds on a few websites like Freegamer, LinuxGames, HappyPenguin and Penguspy. Every now and them i browse Wikipedia articles on free/FOSS games. For commercial games the procedure depends on what i enjoyed the most in that game:- If i enjoyed the story or the general feel: i usually start with a game i like and look for sequels, prequels, mods or spinoffs. I even go out on a limb and give other platforms (than a PC) a try, even if it usually means emulation. If you really enjoy a game series/saga it’s usually worth the effort.- If i enjoy the producer/gaming company then i seek out more of their games.- If i enjoy the technical achievements that went into making the game or if i am concerned for the system requirements of my gear i try to play games that are built on the same engine(s) as one of the games i ran smooth and enjoyed.- If i feel like playing a particular genre i usually start with a title i enjoyed and look for alternatives or similar games- You can always try searching for Game of The Year winners for a particular time period or other similar accomplishments.

• How to avoid throwing vexing exceptions?

  - by Mike

  Reading Eric Lippert's article on exceptions was definitely an eye opener on how I should approach exceptions, both as the producer and as the consumer. However, I'm still struggling to define a guideline regarding how to avoid throwing vexing exceptions. Specifically: Suppose you have a Save method that can fail because a) Somebody else modified the record before you, or b) The value you're trying to create already exists. These conditions are to be expected and not exceptional, so instead of throwing an exception you decide to create a Try version of your method, TrySave, which returns a boolean indicating if the save succeeded. But if it fails, how will the consumer know what was the problem? Or would it be best to return an enum indicating the result, kind of Ok/RecordAlreadyModified/ValueAlreadyExists? With integer.TryParse this problem doesn't exist, since there's only one reason the method can fail. Is the previous example really a vexing situation? Or would throwing an exception in this case be the preferred way? I know that's how it's done in most libraries and frameworks, including the Entity framework. How do you decide when to create a Try version of your method vs. providing some way to test beforehand if the method will work or not? I'm currently following these guidelines: If there is the chance of a race condition, then create a Try version. This prevents the need for the consumer to catch an exogenous exception. For example, in the Save method described before. If the method to test the condition pretty much would do all that the original method does, then create a Try version. For example, integer.TryParse(). In any other case, create a method to test the condition.

• How can I get started using TDD to code some simple functionality?

  - by Gabriel

  I basically have the gist of TDD. I'm sold that it's useful and I've got a reasonable command of the MSTEST framework. However, to date I have not been able to graduate to using it as a primary development method. Mostly, I use it as a surrogate for writing console apps as test drivers (my traditional approach). The most useful thing about it for me is the way it absorbs the role of regression testing. I have not yet built anything yet that specifically isolates various testable behaviors, which is another big part of the picture I know. So this question is to ask for pointers on what the first test(s) I might write for the following development task: I want to produce code that encapsulates task execution in the fashion of producer/consumer. I stopped and decided to write this question after I wrote this code (wondering if I could actually use TDD for real this time) Code: interface ITask { Guid TaskId { get; } bool IsComplete { get; } bool IsFailed { get; } bool IsRunning { get; } } interface ITaskContainer { Guid AddTask(ICommand action); } interface ICommand { string CommandName { get; } Dictionary<string, object> Parameters { get; } void Execute(); }

• How to apply verification and validation on the following example

  - by user970696

  I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

• How to stop worker threads in a multithreaded Windows service on service stop

  - by RobW

  I have a Windows service that uses the producer/consumer queue model with multiple worker threads processing tasks off a queue. These tasks can be very long running, in the order of many minutes if not hours, and do not involve loops. My question is about the best way to handle the service stop to gracefully end processing on these worker threads. I have read in another SO question that using thread.Abort() is a sign of bad design, but it seems that the service OnStop() method is only given a limited amount of time to finish before the service is terminated. I can do sufficient clean-up in the catch for ThreadAbortException (there is no danger of inconsistent state) so calling thread.Abort() on the worker threads seems OK to me. Is it? What are the alternatives?

• how to push data from BlazeDS without recieve message from Flex client?

  - by Teerasej

  Hi, everyone I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer, so I think you can help me. In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want? How to configure the message-config.xml to get the result like I describe above?

• .net 4.0 concurrent queue dictionary

  - by freddy smith

  I would like to use the new concurrent collections in .NET 4.0 to solve the following problem. The basic data structure I want to have is a producer consumer queue, there will be a single consumer and multiple producers. There are items of type A,B,C,D,E that will be added to this queue. Items of type A,B,C are added to the queue in the normal manner and processed in order. However items of type D or E can only exist in the queue zero or once. If one of these is to be added and there already exists another of the same type that has not yet been processed then this should update that other one in-place in the queue. The queue position would not change (i.e. would not go to the back of the queue) after the update. Which .NET 4.0 classes would be best for this?

• Dependency Injection with @Inject in Weld (JSR-299 RI). How is the corresponding @Produces found?

  - by Thorbjørn Ravn Andersen

  I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic. My question is how the producer of a given object to be @Inject'ed is found? Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach. What is the trick?

• Java/C++ communication via pipe on Windows

  - by Warlax

  Hi, I have two separate programs, one in Java and one in C++, both running on Windows. We need to do bidirectional interprocess communication between the two. Up until now, we were using this awkward solution of writing to text files and reading them on the other side, where the producer would generate a .lock file when it's done writing and the consumer would remove that when it's done reading... like I said, awkward. If we were on *nix, we would use a pipe using popen() on the C++ and RadomAccessFile on the Java side. It seems to work well. What can we do on Windows? Can we use named pipes? Thank you.

• Multiple Producers Single Consumer Queue

  - by Talguy

  I am new to multithreading and have designed a program that receives data from two microcontroller measuring various temperatures (Ambient and Water) and draws the data to the screen. Right now the program is singly threaded and its performance SUCKS A BIG ONE. I get basic design approaches with multithreading but not well enough to create a thread to do a task but what I don't get is how to get threads to perform seperate task and place the data into a shared data pool. I figured that I need to make a queue that has one consumer and multiple producers (would like to use std::queue). I have seen some code on the gtkmm threading docs that show a single Con/Pro queue and they would lock the queue object produce data and signal the sleeping thread that it is finished then the producer would sleep. For what I need would I need to sleep a thread, would there be data conflicts if i didn't sleep any of the threads, and would sleeping a thread cause a data signifcant data delay (I need realtime data to be drawn 30 frames a sec) How would I go about coding such a queue using the gtkmm/glibmm library.

• How to set order of appearance for fields when using Html.EditorFor in MVC 2?

  I have the following classes in my Model: public abstract class Entity : IEntity { [ScaffoldColumn(false)] public int Id { get; set; } [Required,StringLength(500)] public string Name { get; set; } } and public class Model : SortableEntity { [Required] public ModelType Type { get; set; } [ListRequired] public List<Producer> Producers { get; set; } public List<PrintArea> PrintAreas { get; set; } public List<Color> Colors { get; set; } } To display the "Model" class in the view I simply call Html.EditorFor(model=model), but the "Name" property of the base class is rendered last, which is not the desired behaviour. Is it possible to influenece on the order of displayed fields somehow?

• Active MQ showing more than one (ghost) consumer

  - by Shoey

  We have a system that uses ActiveMQ (Queues) - and have exactly one producer and one consumer (implemented as a Windows Service in .NET). Over the weekend, the infrastructure team had a reboot of the servers on the network, and from then on we noticed that there are more than one ghost consumer appearing that listens to the queue and we also suspect reads and deletes the messages. My questions are: is there any way from the Active MQ management console to find out what the consumers are (hostnames, etc). and Are there any scenarios in which inadvertent consumers get 'created'? For instance, there were suggestions about the active MQ journal folders getting corrupted after a reboot, or there is another suggestion that another machine with Active MQ broker automatically makes itself a consumer of all the queues on the main/live active mq server.

• Storing task state between multiple django processes

  - by user366148

  I am building a logging-bridge between rabbitmq messages and Django application to store background task state in the database for further investigation/review, also to make it possible to re-publish tasks via the Django admin interface. I guess it's nothing fancy, just a standard Producer-Consumer pattern. Web application publishes to message queue and inserts initial task state into the database Consumer, which is a separate python process, handles the message and updates the task state depending on task output The problem is, some tasks are missing in the db and therefore never executed. I suspect it's because Consumer receives the message earlier than db commit is performed. So basically, returning from Model.save() doesn't mean the transaction has ended and the whole communication breaks. Is there any way I could fix this? Maybe some kind of post_transaction signal I could use? Thank you in advance.

• Firefox 17.0.1 ignoring font-weight

  - by jphogan

  http://iamsinc.com/blog/new-producer-bonus/ For some reason Firefox 17.0.1 on my Windows 7 machine is ignoring the font-weight of the td elements. It should be normal. This works fine in Chrome, IE 7 8, & 9, but not in FF. I have also tested it on an XP machine running 17.0.1 and it works fine. The font-weight should be normal, not bold. In the second box down ($300k level), the font-weight is showing up as bold on Win 7 FF 17.0.1 which pushes the pictures outside of the box. I have even tried reducing the font-weight waaay down and it has not effect on the problematic FF browser Does anybody have a solution or even a work-around? I hate to make the pictures all smaller just to work around this. Thanks!

• Is it possible (and if so how) to delete a zookeeper node with apache camel?

  - by b_habegger

  I am looking into using Zookeeper to synchronized distributed Camel instances. In doing so it seems that there is not possibility to delete a znode from Zookeeper from Camel (I imagined some sort of producer operation). A look at the components source seems to confirm this. (I didn't find any code explicitely requesting a node removal). Am I missing something ? When would a node created via Camel (in my case EPHEMERAL) be deleted ? Maybe I am miss understanding something with zookeeper ?

• Partition Wise Joins II

  - by jean-pierre.dijcks

  One of the things that I did not talk about in the initial partition wise join post was the effect it has on resource allocation on the database server. When Oracle applies a different join method - e.g. not PWJ - what you will see in SQL Monitor (in Enterprise Manager) or in an Explain Plan is a set of producers and a set of consumers. The producers scan the tables in the the join. If there are two tables the producers first scan one table, then the other. The producers thus provide data to the consumers, and when the consumers have the data from both scans they do the join and give the data to the query coordinator. Now that behavior means that if you choose a degree of parallelism of 4 to run such query with, Oracle will allocate 8 parallel processes. Of these 8 processes 4 are producers and 4 are consumers. The consumers only actually do work once the producers are fully done with scanning both sides of the join. In the plan above you can see that the producers access table SALES [line 11] and then do a PX SEND [line 9]. That is the producer set of processes working. The consumers receive that data [line 8] and twiddle their thumbs while the producers go on and scan CUSTOMERS. The producers send that data to the consumer indicated by PX SEND [line 5]. After receiving that data [line 4] the consumers do the actual join [line 3] and give the data to the QC [line 2]. BTW, the myth that you see twice the number of processes due to the setting PARALLEL_THREADS_PER_CPU=2 is obviously not true. The above is why you will see 2 times the processes of the DOP. In a PWJ plan the consumers are not present. Instead of producing rows and giving those to different processes, a PWJ only uses a single set of processes. Each process reads its piece of the join across the two tables and performs the join. The plan here is notably different from the initial plan. First of all the hash join is done right on top of both table scans [line 8]. This query is a little more complex than the previous so there is a bit of noise above that bit of info, but for this post, lets ignore that (sort stuff). The important piece here is that the PWJ plan typically will be faster and from a PX process number / resources typically cheaper. You may want to look out for those plans and try to get those to appear a lot...

• Get to Know a Candidate (11 of 25): Roseanne Barr&ndash;Peace &amp; Freedom Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Barr is an American actress, comedienne, writer, television producer, and director.  Barr began her career in stand-up comedy at clubs before gaining fame for her role in the sitcom Roseanne. The show was a hit and lasted nine seasons, from 1988 to 1997. She won both an Emmy Award and a Golden Globe Award for Best Actress for her work on the show. Barr had crafted a "fierce working-class domestic goddess" persona in the eight years preceding her sitcom and wanted to do a realistic show about a strong mother who was not a victim of patriarchal consumerism. The granddaughter of immigrants from Europe and Russia, Barr was the oldest of four children in a working-class Jewish Salt Lake City family; she was also active in the LDS Church.

From its inception, Peace and Freedom Party has been a left-wing political organization. It is a strong advocate of protecting the environment from pollution and nuclear waste. It advocates personal liberties and universal, high quality and free access to education and health care. Its understanding of socialism includes a socialist economy, where industries, financial institutions, and natural resources are owned by the people as a whole and democratically managed by the people who work in them and use them.
