• Complex "validation rule" using Java Bean code

  Hello
  
  I've never used with jdeveloper validation rules, but I need a complex validation rule to a column of my table.
  
  Can I put a 'validation rule' on an attribute of an object of display or on a column in a table, using the Bean code?
  
  My column must contain different values depending on the other columns in the table, so I think I can't do this without java code...
  
  I tried to doubleClick on column to create a validator, but I put a 'printing' inside and saw that running many times, but I want to run validation only when the value of the column change!
  
  How can I do this? What should I use?
  
  Kind regards
  Trigger

  Trigger,

  If you want to validate an attribute that is dependent on another attribute - you must upgrade the VO (or EO), not at the level of the attribute. You can write a validator method (which is a Java method) to achieve this. I don't think that nini will work for postings that depend on several attributes.

• Read configuration data source AM from Java Bean code

  Hi experts,

  
  I use Jdev 12.1.3 and I need to read the name of AM Datasource from Java Code, to get a text like "jdbc/nomsourcededonnees.

  
  Is this possible?

  Thank you very much
  Jose.

  This object has methods getURL(), getUser() and others.

  But there is no method as getDataSourceName()

  (AFAIK, jdbc connection "knows" nothing about the Data Source)

  You can try something like this inside your AppModuleImpl class:

  this.getSession () .getEnvironment () .get (Configuration.JDBC_DS_NAME)

• The bean code is not activate when-custom-point-event trigger

  I wrote a java bean to read card reader Omnikey.  It works - almost.  When-custom-point-event is not fired.  Get the key of the reader in the java console, but then follows an exception.  The exeption complains, I believe, m_handler null variable in dispatchMessage() call which is what should be pulled when-custom-point-event in the form. I'm missing something minor and that everything works.  See Oracle Forms java console ATR key followed then path exception at the bottom of this post.  I have to FBean.Enable_Event.  What would be the name of the event listener?   I got the kifani of this example code: https://community.oracle.com/thread/68004------ this example isn't mention or implement a listener.  I just need to return the key and place it in a named text field: test.atr.

  a time new form instance

  FBean.Register_Bean('TEST.) CARD_READER_BEAN_AREA', 1, 'CardReader.CardReaderWrapper');

  FBean.set_logging_mode('TEST.) CARD_READER_BEAN_AREA', 1, FBEAN. LOG_ALL);

  button with when button pressed

  fbean. Invoke('TEST.) CARD_READER_BEAN_AREA', 1, 'main');

  When-custom-point-event

  DECLARE
  eventName varchar2 (30): =: system.custom_item_event;
  eventValues ParamList;
  number of eventValueType;
  tempString varchar2 (100);
  BEGIN
  IF (eventName = "CARDINFO_EVENT") THEN
  eventValues: = get_parameter_list(:system.custom_item_event_parameters);
  get_parameter_attr (eventValues, 'CARDINFO_DATA', eventValueType tempString);
  END IF;

  - Then do something with tempString...
  -for example
  -message ("payload has been: ' |") tempString);
  : test. ATR: = tempString;

• Deployment of Java Bean

  Hello
  
  IM using forms 6i. I want to deploy javabean in my forms.
  
  I had crossed the documentation of oracle to deploy.
  
  Initially, I need to do the following 3 steps to deploy the bean,
  
  * Copy the directory oracle integer and its subdirectories in the directory of classes in < ORACLE_HOME > \orant\forms60\java directory. This will place the JavaBean class files in the location where the Oracle Form Builder can locate them at development time.
  * Place the JAR JavaBean (CalendarWidget.jar) file in the base directory of code used to deploy Oracle Forms 6i Server applications. This will allow the client computer to download the files of class for use when running.
  * Change the HTML page used to launch the Oracle Forms application to reference the JAR file in the tag of the ARCHIVE. This should be added the standard JAR of Oracle Forms Server files and notifies the client JVM which archive files must download before you start the application.
  
  < ARCHIVE = "f60all.jar, CalendarWidget.jar" >
  
  I did the first step. Im trying for the second and third stages.
  
  In the second stage i couldnot understand what actually means 'Codebase directory. I couldn't find the correct path to the base directory of code.
  
  good help will be appreciated...

  Don't rule no 1... your forms should be deployed on the Web... with forms 6i make sure is not client server to get the benefits of Java bean

  Hello

  OK, so you must have the object (for example com.event.agreement@2bd2873) implements Serializable.

  The reason is that the event could be potentially "paged" on the disk, and that's why we need to know how to serialize. It improved later in the code base.

• How to create java beans.

  Hi all
  
  How to create java beans and why we use java bean? Please guide me thanks in advance.
  
  Sarah

  A java bean is a piece of code written in the java language. In the "conditions of forms", a java bean is a piece of code that "reinforces" an element of user interface of standard forms, or create a completely new user interface element. For example, you can create a javabean that enhances a standard textitem, which only allows typing in special characters. An example of a completely new user interface element could be for example a dropdown list control or a slider control. There are a lot of things about java-Bean development and also a lot of javabeans ready to download here http://forms.pjc.bean.over-blog.com/article-26108921.html

• Java Bean works is not on server remote weblogic

  Hi all

  Let's all start, I use oracle 11 G R2, Oracle Weblogic Server 10.5 forms.

  My requirement:

  I need a custom form in my Oracle Application with which the user selects color

  My form:

  The custom form has a button and a JavaBean (ColorPicker) Area

  
  

  I use the Fbean package to register and call colorpicker as java bean

  
  

  My problem:

  The form runs successfully on my weblogic server locally (on my laptop), but when I run the same form on remote weblogic server and click the button to choose the color, nothing happens, and the dose of java console does not display an error

  I added colorpicker.jar to check tag in formsweb.cfg and put the colorpicker.jar in the OracleHome/forms/java directory.

  I tried the jar sign, but no solution

  Please help me

  the problem is now solved, the problem was in the browser to the URL

  the file formsweb.cfg on the remote application server containing sections of configuration multi like this:

  [TEST11G]

  ---------------

  [TEST11]

  ------------------

  [webutil]

  -------------

  etc...

  I was adding the colorpicker.jar to the tag of archive in the TEST11 section, while I am running the form using config TEST11G like this:

  http://aptest:8888/forms/frmservlet? config = test11g

  The problem is in the location of my jar file in the file formsweb.cfg

  Thank you very much.

• Change Guide to Fusion? Creation of opening WLS for Backing Bean Code

  I noticed between the 11.1.1.1.0 and 11.1.1.2.0 Developer Guide of JDev for a subtle change to the code example for a connection programmatically in via WLS:
  
  First note '29.7.2.1 Creating connection to the Backing Bean Code' section of the 11.1.1.1.0 step 4 doLogin method():
  http://download.Oracle.com/docs/CD/E12839_01/Web.1111/b31974/adding_security.htm#BGBFJJJH
  
  Secondly, notes that same named section 30.7.2.1 6 simplified again doLogin():
  http://download.Oracle.com/docs/CD/E15523_01/Web.1111/b31974/adding_security.htm#BGBFJJJH
  
  Specifically, I note in the new 11.1.1.2.0 points out the subtle inclusion of ServletAuthentication.generateNewSessionID (request);
  
  What is what and what is the effect on my request to ADF?
  
  I ask, because we use the example of Steve Muench 129 for dynamic JDBC connections + programmatically the user connection based on the 11.1.1.1.0 notes. For some reason any code of Steve is thrown:
  oracle.jbo.InvalidObjNameException: Houston-25005: view.pageDefs_myAppPageDef object of type Binding definition of the form name is not valid.
  
  .. .when ever I add all links to my pageDef to the page that requires authentication. Go debugging it looks like the JdbcPagePhaseListener is called at a time when the definition of page files will still be initialized (well, that's a guess). This leads me to believe the 11.1.1.1.0 original method of logging via the WLS is not something properly to the connection needed by the ADF.
  
  Can someone give more information above why the doLogin() in the merger Guide method changed between versions please?
  
  With our thanks
  
  CM.

  Hi Chris,

  Wow! Your so quick that you have noticed that there is difference. :)
  I just noticed the note on the line with difference as follows:

  Line 11 ensures that the session for the session ID is changed after the user is successfully authenticated. This is necessary in order to avoid leaving the application open a session fixation attack, that would be a security breach.

  I hope someone can explain that.

  Kind regards
