  • Webcast Q&A: ResCare Solves Content Lifecycle Challenges with Oracle WebCenter

    - by Kellsey Ruppel
    Last week we had the fourth webcast in our WebCenter in Action webcast series, "ResCare Solves Content Lifecycle Challenges with Oracle WebCenter", where customer Joe Lichtefeld from ResCare and Wayne Boerger & Doug Thompson from Oracle Partner TEAM Informatics shared how Oracle WebCenter is powering allowing ResCare to solve content lifecycle challenges, reduce compliance and business risks, and increase adoption of intranet as primary business communication tool In case you missed it, here's a recap of the Q&A.   Joe Lichtefeld, ResCare  Q: Did you run into any issues in the deployment of the platform?A: We experienced very few issues when implementing the content management and search functionalities. There were some challenges in determining the metadata structure. We tried to find a fine balance between having enough fields to provide the functionality needed, but trying to limit the impact to the contributing members.  Q: What has been the biggest benefit your end users have seen?A: The biggest benefit to date is two-fold. Content on the intranet can be maintained by the individual contributors more timely than in our old process of all requests being updated by IT. The other big benefit is the ability to find the most current version of a document instead of relying on emails and phone calls to track down the "current" version. Q: Was there any resistance internally when implementing the solution? If so, how did you overcome that?A: We experienced very little resistance. Most of our community groups were eager to be able to contribute and maintain their information. We had the normal hurdles of training and follow-up training with implementing a new system and process. As our second phase rolled out access to all employees, we have received more positive feedback on the accessibility of information. Wayne Boerger & Doug Thompson, TEAM Informatics Q: Can you integrate multiple repositories with the Google Search Appliance? Yes, the Google Search Appliance is designed to index lots of different repositories, from both public and internal sources. There are included connectors to many repositories, such as SharePoint, databases, file systems, LDAP, and with the TEAM GSA Connector and the Oracle Content Server. And the index for these repositories can be configured into different collections depending on the use cases that each customer has, and really, for each need within a customer environment. Q: How many different filters can you add when the search results are returned? A: Presuming this question is about the filtering on the search results. You can add as many filters as you like and it can be done by collection or any number of other criteria. Most importantly, customers now have the ability to limit the returned content by a set metadata value. Q: With the TEAM Sites Connector, what types of content can you sync? A: There’s really no limit; if it can be checked into the content server, then it is eligible for sync into Sites.  So basically, any digital file that has relevance to a Sites implementation can be checked into the WC Content central repository and then the connector can/will manage it. Q: Using the Connector, are there any limitations around where in Sites that synced content can be used? A: There are no limitations about where it can be used. When setting up your environment to use it, you just need to think through the different destinations on the Sites side that might use the content; that way you’ve got the right information to create the rules needed for the connector. If you missed the webcast, be sure to catch the replay to see a live demonstration of WebCenter in action!  ResCare Solves Content Lifecycle Challenges with Oracle WebCenter from Oracle WebCenter

  • Welcome To The Nashorn Blog

    - by jlaskey
    Welcome to all.  Time to break the ice and instantiate The Nashorn Blog.  I hope to contribute routinely, but we are very busy, at this point, preparing for the next development milestone and, of course, getting ready for open source. So, if there are long gaps between postings please forgive. We're just coming back from JavaOne and are stoked by the positive response to all the Nashorn sessions. It was great for the team to have the front and centre slide from Georges Saab early in the keynote. It seems we have support coming from all directions. Most of the session videos are posted. Check out the links. Nashorn: Optimizing JavaScript and Dynamic Language Execution on the JVM. Unfortunately, Marcus - the code generation juggernaut,  got saddled with the first session of the first day. Still, he had a decent turnout. The talk focused on issues relating to optimizations we did to get good performance from the JVM. Much yet to be done but looking good. Nashorn: JavaScript on the JVM. This was the main talk about Nashorn. I delivered the little bit of this and a little bit of that session with an overview, a follow up on the open source announcement, a run through a few of the Nashorn features and some demos. The room was SRO, about 250±. High points: Sam Pullara, from Twitter, came forward to describe how painless it was to get Mustache.js up and running (20x over Rhino), and,  John Ceccarelli, from NetBeans came forward to describe how Nashorn has become an integral part of Netbeans. A healthy Q & A at the end was very encouraging. Meet the Nashorn JavaScript Team. Michel, Attila, Marcus and myself hosted a Q & A. There was only a handful of people in the room (we assume it was because of a conflicting session ;-) .) Most of the questions centred around Node.jar, which leads me to believe, Nashorn + Node.jar is what has the most interest. Akhil, Mr. Node.jar, sitting in the audience, fielded the Node.jar questions. Nashorn, Node, and Java Persistence. Doug Clarke, Akhil and myself, discussed the title topics, followed by a lengthy Q & A (security had to hustle us out.) 80 or so in the room. Lots of questions about Node.jar. It was great to see Doug's use of Nashorn + JPA. Nashorn in action, with such elegance and grace. Putting the Metaobject Protocol to Work: Nashorn’s Java Bindings. Attila discussed how he applied Dynalink to Nashorn. Good turn out for this session as well. I have a feeling that once people discover and embrace this hidden gem, great things will happen for all languages running on the JVM. Finally, there were quite a few JavaOne sessions that focused on non-Java languages and their impact on the JVM. I've always believed that one's tool belt should carry a variety of programming languages, not just for domain/task applicability, but also to enhance your thinking and approaches to problem solving. For the most part, future blog entries will focus on 'how to' in Nashorn, but if you have any suggestions for topics you want discussed, please drop a line.  Cheers.

  • Set focus on textbox in WPF from view model (C#) & wPF

    - by priyanka.sarkar
    I have a TextBox and a Button in my view. Now I am checking a condition upon button click and if the condition turns out to be false, displaying the message to the user, and then I have to set the cursor to the text box control. if (companyref == null) { Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation cs = new Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation(); MessageBox.Show("Company does not exist.", "Error", MessageBoxButton.OK, MessageBoxImage.Exclamation); cs.txtCompanyID.Focusable = true; System.Windows.Input.Keyboard.Focus(cs.txtCompanyID); } The above code is in the view model. The CompanyAssociation is the view name. But the cursor is not getting set in the TextBox. The xaml is as under <igEditors:XamTextEditor KeyDown="xamTextEditorAllowOnlyNumeric_KeyDown" Name="txtCompanyID" ValueChanged="txtCompanyID_ValueChanged" Text="{Binding Company.CompanyId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="{Binding ActualWidth, ElementName=border}" Grid.Column="1" Grid.Row="0" VerticalAlignment="Top" Margin="0,5,0,0" HorizontalAlignment="Stretch" IsEnabled="{Binding Path=IsEditable}" /> <Button Template="{StaticResource buttonTemp1}" Command="{Binding ContactCommand}" CommandParameter="searchCompany" Content="Search" Width="80" Grid.Column="2" Grid.Row="0" VerticalAlignment="Top" Margin="0" HorizontalAlignment="Left" IsEnabled="{Binding Path=IsEditable}" /> Please help

  • iPad. UIBarButtonItem has an undocumented view of type UIToolbarTextButton. Huh?

    - by dugla
    I have an iPad app where I have a view controller that is the UIGestureRecognizerDelegate for a number of UIGestureRecognizers. I have implemented the following method of UIGestureRecognizerDelegate: - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { // Double tapping anywhere on the screen hides/shows the toolbar if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]] == YES) { if (touch.tapCount == 2) { self.toolbar.hidden = self.toolbar.isHidden ? NO : YES; } // if (touch.tapCount == 2) } // if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]] == YES) // All gestures are ignored unless they happen on the fullscreen EAGLView if ([touch.view isKindOfClass:[EAGLView class]] == NO) { return NO; } // if ([touch.view isKindOfClass:[EAGLView class]] == NO) return YES; } My setup is a fullscreen EAGLView with a UIToolbar atop the EAGLView. There is a UIBarButtonItem on the toolbar. The idea here is that double-tapping anywhere toggles the appearance of the toolbar. All other gestures must occur on the EAGLView. My problem is that taps directly on the UIBarButtonItem show touch.view to be the UIView subclass UIToolbarTextButton which is undocumented and can't be introspected. Huh? Can someone suggest a work around, preferably that uses introspective goodness of some form? Thanks, Doug Thanks, Doug

  • Big Data – Buzz Words: What is Hadoop – Day 6 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned what is NoSQL. In this article we will take a quick look at one of the four most important buzz words which goes around Big Data – Hadoop. What is Hadoop? Apache Hadoop is an open-source, free and Java based software framework offers a powerful distributed platform to store and manage Big Data. It is licensed under an Apache V2 license. It runs applications on large clusters of commodity hardware and it processes thousands of terabytes of data on thousands of the nodes. Hadoop is inspired from Google’s MapReduce and Google File System (GFS) papers. The major advantage of Hadoop framework is that it provides reliability and high availability. What are the core components of Hadoop? There are two major components of the Hadoop framework and both fo them does two of the important task for it. Hadoop MapReduce is the method to split a larger data problem into smaller chunk and distribute it to many different commodity servers. Each server have their own set of resources and they have processed them locally. Once the commodity server has processed the data they send it back collectively to main server. This is effectively a process where we process large data effectively and efficiently. (We will understand this in tomorrow’s blog post). Hadoop Distributed File System (HDFS) is a virtual file system. There is a big difference between any other file system and Hadoop. When we move a file on HDFS, it is automatically split into many small pieces. These small chunks of the file are replicated and stored on other servers (usually 3) for the fault tolerance or high availability. (We will understand this in the day after tomorrow’s blog post). Besides above two core components Hadoop project also contains following modules as well. Hadoop Common: Common utilities for the other Hadoop modules Hadoop Yarn: A framework for job scheduling and cluster resource management There are a few other projects (like Pig, Hive) related to above Hadoop as well which we will gradually explore in later blog posts. A Multi-node Hadoop Cluster Architecture Now let us quickly see the architecture of the a multi-node Hadoop cluster. A small Hadoop cluster includes a single master node and multiple worker or slave node. As discussed earlier, the entire cluster contains two layers. One of the layer of MapReduce Layer and another is of HDFC Layer. Each of these layer have its own relevant component. The master node consists of a JobTracker, TaskTracker, NameNode and DataNode. A slave or worker node consists of a DataNode and TaskTracker. It is also possible that slave node or worker node is only data or compute node. The matter of the fact that is the key feature of the Hadoop. In this introductory blog post we will stop here while describing the architecture of Hadoop. In a future blog post of this 31 day series we will explore various components of Hadoop Architecture in Detail. Why Use Hadoop? There are many advantages of using Hadoop. Let me quickly list them over here: Robust and Scalable – We can add new nodes as needed as well modify them. Affordable and Cost Effective – We do not need any special hardware for running Hadoop. We can just use commodity server. Adaptive and Flexible – Hadoop is built keeping in mind that it will handle structured and unstructured data. Highly Available and Fault Tolerant – When a node fails, the Hadoop framework automatically fails over to another node. Why Hadoop is named as Hadoop? In year 2005 Hadoop was created by Doug Cutting and Mike Cafarella while working at Yahoo. Doug Cutting named Hadoop after his son’s toy elephant. Tomorrow In tomorrow’s blog post we will discuss Buzz Word – MapReduce.

  • Why, on iOS, is glRenderbufferStorage appearing to fail?

    - by dugla
    On an iOS device (iPad) I decided to change the storage for my renderbuffer from the CAEAGLLayer that backs the view to explicit storage via glRenderbufferStorage. Sadly, the following code fails to result in a valid FBO. Can someone please tell me what I missed?: glGenFramebuffers(1, &m_framebuffer); glBindFramebuffer(GL_FRAMEBUFFER, m_framebuffer); glGenRenderbuffers(1, &m_colorbuffer); glBindRenderbuffer(GL_RENDERBUFFER, m_colorbuffer); GLsizei width = (GLsizei)layer.bounds.size.width; GLsizei height = (GLsizei)layer.bounds.size.height; glRenderbufferStorage(m_colorbuffer, GL_RGBA8_OES, width, height); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, m_colorbuffer); Note: The layer size is valid and correct. This is solid production working rendering code. The only change I am making is the line glRenderbufferStorage(...) previously I did: [m_context renderbufferStorage:GL_RENDERBUFFER fromDrawable:layer] Thanks, Doug

  • SOA Galore: New Books for Technical Eyes Only

    - by Bob Rhubart
    In my part of the world the weather has taken its seasonal turn toward the kind of cold, damp, miserable stuff that offers a major motivation to stay indoors. While I plan on spending some of that indoor time working my way through the new 50th anniversary James Bond box set, I will also devote some time to improving my mind rather than my martini-mixing skills by catching up on my reading. If you're in a similar situation, you might want to spend some of your time  with these new technical books written by community members: Oracle SOA Suite 11g Administrator's Handbook by Ahmed Aboulnaga and Arun Pareek. Oracle BPM Suite 11g: Advanced BPMN Topics by Mark Nelson and Tanya Williams Oracle SOA Suite 11g Developer's Cookbook by Antony Reynolds and Matt Wright (Coming in December; available for pre-order).

  • Monitor Display issue

    - by dsiddens
    When booting I will have to boot maybe 3 or 4 times to get a screen that is not displayed diagonally or is not using the full screen width. Hardware specification: HP s7727c with AMD64 and NVIDIA chipsets and Insignia 22" monitor/TV. The Ubuntu version is 9.10 Karmic. I'd like to stay current with Ubuntu on this machine, but have gone down to 9.10 to get this described functioning. I tried higher versions and could not get past the "black screen" I think this issue is connected to the NVIDIA chipset/driver problem. I am a GUI user and I don't follow the other solutions posted which make use of the command line. I suppose if the command line solution could be given without making any assumptions of the receiving person's knowledge base, then even I and others like me, could implement it. Thank you for your time and assistance. Doug

  • UIPopoverController. Is there way to use Interface Builder to layout the VC and View it Contains?

    - by dugla
    Since UIPopoverController is often a container for a non-trivial amount of view hierarchy, it would be nice to do the layout of the VC and View it contains in Interface Builder rather then programmatically. Has anyone found a good work flow for do this? For example I want to embed a UIScrollView in a UIPopoverController and I am not excited about having to do it all programmatically. Thanks in advance. Cheers, Doug
