• [ADF, JDev12.1.3] Which is the best way to define the properties of CIU/fragments of pages. Is the approach that I have used a good choice (for a beginner)?

  Hallo,

  in my app, that I have a lot of pages and fragments in which properties (for example rendered text, disabled, Selected,...), lots of user interface components must be set, before/when the page is displayed, depending on the session and pageFlow scope attributes.

  So far I have created for each page/one backingBean brought bean fragment in which I defined an attribute for each property defined (e.g. 2 properties for each UIC: UIC is 10...) "I have 20 attributes to manage in the bean).

  Then, I linked each attribute of the bean to the respective UIC property. You can see in this my thread (unfortunately without answers ) [ADF, JDev12.1.3] backingBean bean: a lot of properties to set for lots of CIU... is better by using the properties of the binding or access code (created by ID) UIC? a small example. I put the attributes the bean Builder (or in a function of 'action' if the APP properties must be set based on the interaction of the user).

  I would like to know:

  • If it is a good approach / recommended / safe or if there is a better way;
  • If the scope backingBean is OK, or if a larger scope would be better.

  As I asked in the thread in the link above, the situation can become difficult to manage if the PPP for which setting, properties are very different.

  So I'd like if there is no alternative that I can use to get the same result with less effort.

  For example, using the class ComponentReference or invokeOnComponentAPI could simplify my life? And their use could I always use backingBean brought beans?

  Thank you

  Federico, please understand that this forum has no sla. I have other work to do, who pays my bills. I will do my best to help, but you can not expect the instant replay.

  (1) you must not use the bean to init your beans. You can delay load or init your beans instead.

  (2) as Frank and says you can use a bean to view range and use it to make your calculations as long as you know how their parameters go to the btf

  (3) you should always use the reference of the component if you bind a component to a bean. Make a habit of all scopes.

  As we do not know how you calculate the State and how often it changes while the Working Group is on the page, it is difficult to give further advice.

• SSD: Which method of installation is the best?

  I install my first Samsung SSD in a new XPS 8700.  It will be the boot drive for the Windows 7 operating system and program applications.  I have 3 options and am trying to decide which route to go:

  1. Use the migration software provided with the SSD drive for quick transfer.  Apparently, it does not copy the Dell partition.
  2. Installing from the Dell System Restore DVD I did when I ran the system.  This restores the Dell, or just the OS partition?
  3. A new installation of Windows 7 using the OS disc (which I have).  No Dell partition with this method.  Drivers must be installed.  I have the Dell drivers (rev A00) disk, dated April 2013, so I don't know how current drivers are out there, but I can download the most recent.  This method would require special SATA drivers be loaded during the installation?

  And what I need to do any special partitioning?   Thanks for your suggestions/comments.

  None of the special SATA drivers not necessary, and I would recommend to go with option 3: the new installation of Windows 7. Download the latest drivers for Win7 64 bit for Dell website, but I do not recommend updated the A06 BIOS/UEFI. Stick with A03 if that's what you already have. You can use a free application like 'Speccy' to see what you have (in the "motherboard" section). Also check that you are running in mode "AHCI" (as opposed to "IDE") in the BIOS/UEFI.

  If your 8700 was running Windows 7 and nothing additional is needed beyond what is mentioned above. But if your XPS 8700 has been running Windows 8/8.1, you will need change some settings in the BIOS/UEFI before installing Windows 7. If this is the case for you, here's how to (search the page for "XPS 8700"):

• [ADF, JDev12.1.3] LOV entry: is it possible to change the criteria to view / query to use before the opening of the popup?

  Hallo,

  I would like to know if it is possible to change the criteria for the view or the query used by an LOV entry before the opening of the pop-up window (on the click the icon in the search).

  Thank you

  Federico

  You can change the implicit vc used by the LOV, overwriting the popuplistener and a different VC as

  {} public void onLauchLov (LaunchPopupEvent launchPopupEvent)

  String submittedValue = (String) launchPopupEvent.getSubmittedValue ();

  run the queries only if value is submitted

  If (submittedValue! = null & submittedValue.length () > 0) {}

  RichInputListOfValues lovComp = launchPopupEvent.getComponent ((RichInputListOfValues));

  BindingContext bindingCtx = BindingContext.getCurrent ();

  BindingContainer links = bindingCtx.getCurrentBindingsEntry ();

  JUCtrlListBinding lov = bindings.get ("JobId") (JUCtrlListBinding);

  VCM ViewCriteriaManager = lov.getListIterBinding () .getViewObject () .getViewCriteriaManager ();

  ensure that the criteria of display is disabled

  vcm.removeViewCriteria (ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);

  Create a new view of the criteria of

  ViewCriteria vc = new ViewCriteria (lov.getListIterBinding () .getViewObject ());

  Use the name of the default view criteria

  '__DefaultViewCriteria__ '.

  vc.setName (ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);

  create a display for all queryable attributes criteria

  VCR ViewCriteriaRow = new ViewCriteriaRow (vc);

  for this example, I put the query filter for 60 DepartmentId.

  You can determine when running in reading to a managed bean

  or the link layer

  vcr.setAttribute ("JobId", submittedValue + "%");

  Note also that the line of view criteria consists of all attributes

  who belong to the view list LOV object, which means that you can

  filter on multiple attributes

  vc.addRow (vcr);

  lov.getListIterBinding () .getViewObject () .applyViewCriteria (vc);

  }

  }

• [ADF, JDev12.1.3] Form based on EO VO istance basis: which is the best place where to score the extra required fields?

  Hallo,

  I created a form of a base EO VO istance.

  The EO has auto-marqué as asterisk fields in the db table on which it is based.

  Self-validation as happens on these fields, but I want to force the user to fill in the other fields.

  What is the best blace where to add other fields of cumpolsory?

  So far, I did it in the attributes of the OS... but I would like to know if it's OK.

  Thank you

  Federico

  Yes, this is logical job for each line that is the place to mark the attribute as mandatory.

  In this way, the validation is done as for the other attributes.

• [ADF, JDev12.1.3] Best practices for maintaining a form validation

  Hallo,

  in my application, I need to create a registration form which contains fields that must be validated (for example they should follow a format like e-mail, phone number, tax code,...).

  If the data inserted by the user are ok, a new record in my custom db table Users will be created.

  I would like to know which are the best practices for maintaining the validation, which means the place where the controls must be made and a message to the user who fills out the form when something goes wrong.

  The best vo or EO or managed bean? Or some controls should be put in the OS, others in the VO and other in the managed bean?

  I would be happy if you could give me some examples.

  Thank you

  Federico

  Assuming you want the validation on the value of the field to any screen data can be entered in (and possibly web services that rely on the same BC ADF) then put the validation on the definition of the attribute in the EO.

  If you want to add a little more friendliness and eliminate some of the network traffic to the server, you can also implement the validation client in your page - for example by using the regular expression validator.

• [ADF, JDev12.1.3] Managed beans: when I have to worry about serialization (de)?

  Hallo,

  I would like to know what type of beans and in which case, I have to worry about serialization (de).

  When is it enough to simply add implements Serializable class definition? Which is the right class to import?

  And when I really need to implement (de) serialization by myself and how I can do? One (or more) example forward.

  For example, in a range session bean I use a recorder and some standard attributes...

  public class Login  {
    private final Logger logger = oaw.model.Config.getLogger(Login.class.getName());
    String A;
    Integer X;
    // ...
  }
  
  

  ... what should I do?

  In general, if a bean stores no data (de) serialization has no matter, right?

  Information you provide me... better is

  Thank you

  Federico

  I would like to know what type of beans and in which case, I have to worry about serialization (de).

  In all the grains that can survive a http request-response cycle.

  It is usually related to clustering, but it may be important if you use UserData structure in AM.

  When is - it enough to simply add implements Serializable class definition? Which is the right class to import?

  When you have java simple types or types that already implement the Serializable interface.

  See: Serializable (Java SE 7 platform)

  For example, in a range session bean I use a recorder and some standard attributes...

  1. public class {Login
  2. private final Logger logger = oaw.model.Config.getLogger (Login.class.getName ());
  3. String A;
  4. Integer X;
  5. // ...
  6. }

  ... what should I do?

  Just mark your connection with the Serializable attribute class.

  In general, if a bean stores no data (de) serialization has no matter, right?

  Right.

  Thank you

  I don't know if it's the right answer for your question try this...

• [ADF, JDev12.1.3] master / detail af:tables the link is handled by ExecuteWithParams: how to create a master report / detail in a loop on the lines?

  Hallo,

  I have a page with 2 legs and they both contains an af:table created by dragging an instance of VO in the user interface.

  The 1st tab uses a master VO while the 2nd uses a VO detail.

  Between 2 your, there is not a link of VO master / detail.

  Opening Details tab I update the secondary table by calling the method ExecuteWithParams of the detail VO instance (in a managed bean).

  I would now like to generate a report that loop on the master table and that, for each line of master:

  • He writes in the report;
  • loops of registration of details (which are based on the master record) and also writes the report.

  
  

  Could you kindly suggest me which is the best way to achieve that through a code to write in a managed bean?

  Here I am interested how do to loop through the data, not in how to write the report.

  Thank you

  Federico

  Yes it will affect the selected line. If you want to ignore try using this code

      DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("DepartmentsView1Iterator");
      ViewObject vo = iter.getViewObject();
      for (int i = 0; i < vo.getEstimatedRowCount(); i++)
      {
        Row r = vo.getRowAtRangeIndex(i);
        System.out.println("DeptId= " + r.getAttribute("DepartmentId"));

• Where to put the java code - best practices

  Hello. I work with the Jdeveloper 11.2.2. I'm trying to understand the best practices for where to put the code. After reviewing the http://docs.oracle.com/cd/E26098_01/web.1112/e16182.pdf, it seemed that request module was the preferred location (although many examples in the pdf file reside in the main methods). After some time of coding, if, I noticed that there was a certain libraries imported and wondered if this would impact performance.
  
  I looked at the articles published on the forum, in particular Re: programmatically access the method of service (customer interface) . This link mentions for access to the code a bean of support - and the bulk of the recommendations seem to be using the data control to drag to the Joint Strike Fighter, or use the links to access code.
  
  My interest lies in where to put the java code in the first place; In the view object, entity object, and... other Am, backing bean object?
  
  I can describe several guess better know where to put the code and the advantages and disadvantages:
  
  1. in the application module
  Benefits: Central location for code makes development and support easier as there are not multiple access points. Kinda like a data control centralizes the services, the module of the application can act as a conduit for the different parts of the code you have in your model objects.
  Cons: Everything in one place means that the module of the application becomes bloated. I don't know how the memory works in java - if the app module has tons of different libraries are all called when even a method of re - run a simple query is called? Memory of pigs?
  
  2. write the code in the objects it affects. If you write code that accesses a view object, write it to a display object. Then make it visible for the customer.
  benefits: the code is accessible through ducts less (for example, I expect that if you call the module from the application of a JSF backing bean, then the module of the application calls the view object, you have three different pieces of code-)
  CONT: the code gets spread, more difficult to locate etc.
  
  I would greatly appreciate your thought on the issue.
  
  
  Kind regards

  First point here is when you say 'where to put the code of java' and you're referring to ADF BC, the point is that you put 'code of java business logic' in the ADF business components. Of course it is very good to have the Java code in the ViewController layer that covers the user interface layer. Just don't put the business logic in the user interface layer and don't put no logical user interface in the model layer. In your 2 examples you seem to consider the ADF BC layer only, so I'll assume that you're not only serious logic java code.

  Meanwhile, I'm not keen on best practices in the term that people are following best practices without thinking, usually best practices come with conditions and forget to apply. Fortunately you do not here that you have thought through the pros and cons of each (nice work).

  Anyway, back on topic and turn off my soap box, regarding where to put your code, my thoughts:

  (1) If you have only 1 or 2 methods set in the AppModuleImpl

  (2) If you have hundreds of methods, or there is that a chance #1 above will turn into #2, divide the code between the AppModuleImpl, the ViewImpl and the ViewRowImpls. Why? Because your AM will become overloaded with hundreds of methods making it unreadable. Put the code where it should logically go instead. Methods that operate on a specific line of VO Approfondissez partner ViewRowImpl, methods that work across lines in a VO enter the ViewImpl and methods that work throughout your in the associated AppModuleImpl.

  To be honest that you never the option you choose, one thing I recommend as a best practice is to be consistent and document standard so not know your other programmers.

  BTW, it is not a question about loading a lot of libraries/imports in a class, it has no performance cost. However if your methods require a lot of class variables, then yes there will be a memory of the costs.

  On a side note, if you are interested in more ideas on how to create ADF applications properly think about joining the EMG "ADF", a forum which deals with ADF architecture, best practices (cough), deployment architectures free online and more.

• Java native interface: best practices?

  Hi all
  I'm trying to access a database with the C API from a tomcat/glassfish server by using API native Java.
  
  I put the environment in the context of the application for all users will share the same instance of the database.
  
  first question: is this a good idea? What would be the best practice? can I use this application in a multithreaded environment?
  
  The problem was that the 'System.loadLibrary' method is called whenever my application is redeployed: If an exception was thrown (library already loaded), because the server has already loaded the db library in a previous deployment. To solve the problem, I put a silencer ' try... catch...» "around this System.loadLibrary in the source code of com/sleepycat/db/internal/db_javaJNI.java
  
  2nd question: is there a way to avoid this hack?
  
  Thank you for any response

  Hi Pierre,.

  Sorry for the delay in his response to this request.

  In answer to your first question, it is to access a Berkeley DB environment handle from multiple threads in Java. No specific configuration is required.

  The second question is not specific to Berkeley DB: it applies to any library JNI accessed via a class loader other than the system class loader. For example, see this thread:

  http://forums.Sun.com/thread.jspa?threadID=633985

  In the case of Berkeley DB, where you're unlikely to deploy a version update on the fly, the simplest solution is to make sure that the native library is loaded by the class loader running Tomcat with db.jar common/lib, and no WEB-INF/lib of your webapp.

  Kind regards
