  • How to generate a metamodel for POJOs

    - by Stefan Haberl
    I'm looking for a metamodel generation library for simple Java POJOs. I'm thinking about something along the lines of JPA 2.0's metamodel, which can be used to generate type safe criterias for JPA entities (see this Question on SO for JPA specific implementations). Does something similar exist for general purpose JavaBeans, i.e., POJOS, that are not JPA entities? Specifically, I want to implement Spring MVC's WebDataBinder.setAllowedFields() method in a type safe way in my Spring MVC @Controllers

  • Checking update reason after actual update

    - by KaRo
    Is there a possibility to find out the reason for at least the last automatic update? When the update-window pops up one can click on the entries and find a statement about what bug shall be fixed with a certain package, or more general why it is updated at all. I want to check for this information afterwards to check if a certain bug or functionality is claimed to be fixed already. thx - robert.

  • Let your Signature Experience drive IT-decision making

    - by Tania Le Voi
    Today’s CIO job description:  ‘’Align IT infrastructure and solutions with business goals and objectives ; AND while doing so reduce costs; BUT ALSO, be innovative, ensure the architectures are adaptable and agile as we need to act today on the changes that we may request tomorrow.”   Sound like an unachievable request? The fact is, reality dictates that CIO’s are put under this type of pressure to deliver more with less. In a past career phase I spent a few years as an IT Relationship Manager for a large Insurance company. This is a role that we see all too infrequently in many of our customers, and it’s a shame.  The purpose of this role was to build a bridge, a relationship between IT and the business. Key to achieving that goal was to ensure the same language was being spoken and more importantly that objectives were commonly understood - hence service and projects were delivered to time, to budget and actually solved the business problems. In reality IT and the business are already married, but the relationship is most often defined as ‘supplier’ of IT rather than a ‘trusted partner’. To deliver business value they need to understand how to work together effectively to attain this next level of partnership. The Business cannot compete if they do not get a new product to market ahead of the competition, or for example act in a timely manner to address a new industry problem such as a legislative change. An even better example is when the Application or Service fails and the Business takes a hit by bad publicity, being trending topics on social media and losing direct revenue from online channels. For this reason alone Business and IT need the alignment of their priorities and deliverables now more than ever! Take a look at Forrester’s recent study that found ‘many IT respondents considering themselves to be trusted partners of the business but their efforts are impaired by the inadequacy of tools and organizations’.  IT Meet the Business; Business Meet IT So what is going on? We talk about aligning the business with IT but the reality is it’s difficult to do. Like any relationship each side has different goals and needs and language can be a barrier; business vs. technology jargon! What if we could translate the needs of both sides into actionable information, backed by data both sides understand, presented in a meaningful way?  Well now we can with the Business-Driven Application Management capabilities in Oracle Enterprise Manager 12cR2! Enterprise Manager’s Business-Driven Application Management capabilities provide the information that IT needs to understand the impact of its decisions on business criteria.  No longer does IT need to be focused solely on speeds and feeds, performance and throughput – now IT can understand IT’s impact on business KPIs like inventory turns, order-to-cash cycle, pipeline-to-forecast, and similar.  Similarly, now the line of business can understand which IT services are most critical for the KPIs they care about. There are a good deal of resources on Oracle Technology Network that describe the functionality of these products, so I won’t’ rehash them here.  What I want to talk about is what you do with these products. What’s next after we meet? Where do you start? Step 1:  Identify the Signature Experience. This is THE business process (or set of processes) that is core to the business, the one that drives the economic engine, the process that a customer recognises the company brand for, reputation, the customer experience, the process that a CEO would state as his number one priority. The crème de la crème of your business! Once you have nailed this it gets easy as Enterprise Manager 12c makes it easy. Step 2:  Map the Signature Experience to underlying IT.  Taking the signature experience, map out the touch points of the components that play a part in ensuring this business transaction is successful end to end, think of it like mapping out a critical path; the applications, middleware, databases and hardware. Use the wealth of Enterprise Manager features such as Systems, Services, Business Application Targets and Business Transaction Management (BTM) to assist you. Adding Real User Experience Insight (RUEI) into the mix will make the end to end customer satisfaction story transparent. Work with the business and define meaningful key performance indicators (KPI’s) and thresholds to enable you to report and action upon. Step 3:  Observe the data over time.  You now have meaningful insight into every step enabling your signature experience and you understand the implication of that experience on your underlying IT.  Watch if for a few months, see what happens and reconvene with your business stakeholders and set clear and measurable targets which can re-define service levels.  Step 4:  Change the information about which you and the business communicate.  It’s amazing what happens when you and the business speak the same language.  You’ll be able to make more informed business and IT decisions. From here IT can identify where/how budget is spent whether on the level of support, performance, capacity, HA, DR, certification etc. IT SLA’s no longer need be focused on metrics such as %availability but structured around business process requirements. The power of this way of thinking doesn’t end here. IT staff get to see and understand how their own role contributes to the business making them accountable for the business service. Take a step further and appraise your staff on the business competencies that are linked to the service availability. For the business, the language barrier is removed by producing targeted reports on the signature experience core to the business and therefore key to the CEO. Chargeback or show back becomes easier to justify as the ‘cost of day per outage’ can be more easily calculated; the business will be able to translate the cost to the business to the cost/value of the underlying IT that supports it. Used this way, Oracle Enterprise Manager 12c is a key enabler to a harmonious relationship between the end customer the business and IT to deliver ultimate service and satisfaction. Just engage with the business upfront, make the signature experience visible and let Enterprise Manager 12c do the rest. In the next blog entry we will cover some of the Enterprise Manager features mentioned to enable you to implement this new way of working.

  • Paranoid management, contractor checking work [closed]

    - by user833345
    Just wanted to get some opinions and experiences on an issue I'm having at work. First, a little background. I've been working at a company for some time (past any probation periods) and rewriting a horrendous system. No tests, incomplete and broken functionality everywhere, enough copypasta to feed a small village, redundant code, more unused SQL tables than used ones and terrible performance. I've never seen such bad code, pretty much all of it is worthy of being posted on TheDailyWTF. The company has been operating for a number of years and have had a string of bad developers working on this system. I made a call on rewriting instead of refactoring since I judged it to be less work overall and decided that the result will address the requirements more appropriately, since the central requirement is to have a future-proof system for the next decade with plenty of room to scale up. Refactoring would have entailed untangling a huge ball of yarn and at the same time integrating it with a proper foundation or building a foundation from scratch. I've introduced the latest spiffy framework, unit & functional testing, CI, a bug tracker and agile workflow to the environment. I've fixed most of the performance issues of the old system (there were no indexes on any of the tables, for example). I've created an automated deployment process for the old system. The CTO has been maintaining the old system while I have been building the new one and he has been advising management that everything is being done as per best practices. However, management is hiring a contractor to come in and verify my work. In my experience, this is unprecedented. I can understand their reasoning to an extent, since they've had bad luck in the past, but can't help but feel somewhat offended at the fact that they distrust two senior developers who have been working with them for some time enough that a third party is being brought in. And it's not just me who is under watch - people's emails are constantly checked, someone had a remote desktop application installed on their computer of which I was asked to check the usage logs to try to determine if they were stealing sensitive data and there are CCTV cameras in one of the rooms. It's the first time I've decided to disable my Skype history at work. Am I right to feel indignant here? Has anyone else ever encountered such a situation? If so, how did it work out in the end? Was it worth sticking around? Should I just find another job?

  • What could be the best way to generalize data from Facebook and Twitter?

    - by Sjaak van der Heide
    I am not sure if this is the best subsite to ask this question, but I'm pretty sure it doesn't fit on the normal or facebook SO page... I've been asked to make a general API for connecting to several Social Media platforms (at the moment Facebook and Twitter). I have already realised both of them seperately. Meaning I retrieve the data I need from both Facebook and Twitter and hold the data in it's own dataclass. In my case a list of FacebookTimelineItems and a list of TwitterTimelineItems. now the hard part is taking the parts that are used in both (username, id, message and such) and make 1 general class that is eventually passed on to who/whatever sent the call to my API. these are two pics of the data classes I have: http://imageshack.us/photo/my-images/703/facebookdata.png/ http://imageshack.us/photo/my-images/204/twitterdata.png/ probably not 100% correct but it gives an idea what it looks like. Now I've been having several idea about how to go about and generalize the two, which is harder then I thought at first. Create an interface (TimelineItem) and let the other classes extend that one. this way I'll always be sure I have a class that contains at least the basic info I need. downside is that deserializing the JSON seems to be a nightmare. Use the two dataclasses I have and combine them into a new class afterwards, then pass that one back to whoever requested it. This would probably work but I get the idea it's not the best way to tackle this problem, and is pretty dodgy IF I get it working. Or, in case of the other two being nearly impossible. Keep the two seperated in the front end, and go sit in the corner crying because I've just figured out you can't lump together facebook and twitter... Note: I don't have to make the front end part (view), I just make sure the Model is nicely filled with data :) I hope I placed this in the right section, if I didn't I apologise and would like to know where I should go with my question. Thanks in advance for any replied/ideas/opinions on this.

  • Should I return iterators or more sophisticated objects?

    - by Erik
    Say I have a function that creates a list of objects. If I want to return an iterator, I'll have to return iter(a_list). Should I do this, or just return the list as it is? My motivation for returning an iterator is that this would keep the interface smaller -- what kind of container I create to collect the objects is essentially an implementation detail On the other hand, it would be wasteful if the user of my function may have to recreate the same container from the iterator which would be bad for performance.

  • Are there any concerns with using a static read-only unit of work so that it behaves like a cache?

    - by Rowan Freeman
    Related question: How do I cache data that rarely changes? I'm making an ASP.NET MVC4 application. On every request the security details about the user will need to be checked with the area/controller/action that they are accessing to see if they are allowed to view it. The security information is stored in the database. For example: User Permission UserPermission Action ActionPermission A "Permission" is a token that is applied to an MVC action to indicate that the token is required in order to access the action. Once a user is given the permission (via the UserPermission table) then they have the token and can therefore access the action. I've been looking in to how to cache this data (since it rarely changes) so that I'm only querying in-memory data and not hitting a database (which is a considerable performance hit at the moment). I've tried storing things in lists, using a caching provider but I either run in to problems or performance doesn't improve. One problem that I constantly run in to is that I'm using lazy loading and dynamic proxies with EntityFramework. This means that even if I ToList() everything and store them somewhere static, the relationships are never populated. For example, User.Permissions is an ICollection but it's always null. I don't want to Include() everything because I'm trying to keep things simple and generic (and easy to modify). One thing I know is that an EntityFramework DbContext is a unit of work that acts with 1st-level caching. That is, for the duration of the unit of work, everything that is accessed is cached in memory. I want to create a read-only DbContext that will exist indefinitely and will only be used to read about permission data. Upon testing this it worked perfectly; my page load times went from 200ms+ to 20ms. I can easily force the data to refresh at certain intervals or simply leave it to refresh when the application pool is recycled. Basically it will behave like a cache. Note that the rest of the application will interact with other contexts that exist per request as normal. Is there any disadvantage to this approach? Could I be doing something different?

  • DAX editor for SQL Server

    One of the major criticism to DAX is the lack of a decent editor and more in general of a dedicated IDE, like the one we have for T-SQL or MDX. Well, this is no more true. On Codeplex a very interesting an promising Visual Studio 2010 extension has been released by the beginning of November 2011: http://daxeditor.codeplex.com/ Intellisense, Syntax Highlighting and all the typical features offered by Visual Studio are available also for DAX. Right now you have to download the source code and compile it, and that’s it!
