Managed Bean executable access

Hi Experts,

I want to access a view (from the executable section) in a managed bean criteria. No idea how to do this?

thnks

chk this
http://vtkrishn.WordPress.com/2010/07/21/easiest-way-to-get-the-current-binding-from-the-bean/

For connection of research use it as
Fc = FacesCtrlSearchBinding
(FacesCtrlSearchBinding) bindings.findExecutableBinding ("PeriodQuery");
or
Fc = FacesCtrlSearchBinding
(FacesCtrlSearchBinding) bindings.get ("PeriodQuery");

How to access the managed bean taskflow action result?
Hi all
I have a requirement where I have two areas of text (username and password) and a SignIn button. When the user clicks login, my action managed bean will run the view object and get the password for this user name. And that's why it will compare the password presented by the user and the password came from the view object. I a taskflow, in which I have two points of view, we're signIn page and other is the home page, and the result of the action is successful.
The managed bean method here signIn Page for SignIn button.

public String execute() {}
String EnteredPassword = PassEncrypt();
ApplicationModule am = ADFUtils.getApplicationModuleForDataControl ("AppModuleDataControl");
ViewObject myView1 = am.findViewObject("LogindetailsView1");
System.out.println ("Usrname is" + this.) (Username);
myView1.setNamedWhereClauseParam ("v_Username", this.) (Username);
myView1.executeQuery ();
DCBindingContainer links =
(DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();
DCIteratorBinding empIter = bindings.findIteratorBinding("LogindetailsView1Iterator");
String DBPassword = empIter.getCurrentRow ().getAttribute("Password").toString ();

System.out.println ("password is" + DBPassword);

{if (EnteredPassword.Equals (dbpassword))}

Here, I need to call the result of success, which will allow the user to get access to the display of the home page in taskflow.

}
else {}
FacesMessage fm =
new FacesMessage (FacesMessage.SEVERITY_ERROR, "Please check your name of user and password",
"Please check your name of user and password");
FacesContext.getCurrentInstance () .addMessage (null, fm);
}
Returns a null value.
}

If this can be done using the method call in taskflow then how could use it in my script?
Please suggest.
Thank you.
you have a rule of navigation between these two pages
If so, simply return the navigation rule name
```
if(EnteredPassword.equals(DBPassword)) {
return "success";
}
```

ADF - components of the access to the contents of a managed bean in a HA environment ViewScope.

Hi all
I have a question, I am a beginner with ADF and learn a lot through these forums and Google
Using Jdeveloper 11.1.1.7
is the question I have, I have a cluster/HA environment (2 knots) and move my application to use HA.
I changed the ADF - config.xml to add the following line:
" < adf-controller-config xmlns =" http://xmlns.Oracle.com/ADF/controller/config "> "
< adf-scope-ha-support > true < / adf-scope-ha-support >
< / adf-controller-config >
I currently have a managed bean (ViewScope) and it has all my actionListeners/valueChange etc... etc... It also has my UIComponent links and I have also several methods that define specific attributes on these components and then do:
AdfFacesContext.getCurrentInstance () .addPartialTarget ("ComponentRefHere");
I am aware that I have to put my beans managed to implement Serializable I also understand that the UI components are not serializable.
I use the ComponentReference method that is to say:
```
    private ComponentReference<RichPanelBox> iframePB;

    public void setIframePB(RichPanelBox component) {
        iframePB = ComponentReference.newUIComponentReference(component);
    }
  
    public RichPanelBox getIframePB() {
        return uiComponentBean.getIframePB();
    }
```
is the question I have, I can leave it like that? or will I move them to a different managed bean?
If so, how should I put the bean, it must also implement serializable, and how do I access them from my managed bean viewScope.

Thank you

You don't have to. Https://docs.oracle.com/javaee/6/tutorial/doc/gjbbk.html documentation

The beans that use the scope of the conversation, application, or session must be serializable, but beans that use the scope of the request need not be serializable.

I personally always add the serializable interface as the bean has never should be selected for serialization, it should not control. It is easier to tell everyone to add it anyway. In this way, you can use the same class in all scopes.

How to access all the lines one by one, a table ADF via managed bean
Hi Experts,

Hi I'm new in the ADF.

Could someone help me to fix the case below?

Scenario - I have a table called Test_T1 that have 4 columns C1, C2, C3, C4. Creation of EO, VO and AM for test_t1.
When created in pages ADF, I selected the option "automatically exposed components UI in new managed bean" (mynewmanagedbean.java).
Control data drag and drop Test_T1 table in the page as a table of the ADF.
Set the properties is read-only C1, C2, C3 and C4 is an input text.
Add after the table and attathed button action on the mynewmanagedbean.java bean managed.
At the time of the Test_T1 page filled with a few No.. lines (such as 9).
How can I access all the lines above through the key without selection of these.
In fact, I want to print all the rows of the table in the log at the time to press the button.

Thanks in advance.
Sorry for the delay, the code was copied from another test case. You can work directly with the line...
I created a new test case based on the departments of the HR schema table:
```
import oracle.adf.model.BindingContext;
import oracle.adf.model.bean.DCDataRow;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.adf.share.logging.ADFLogger;

import oracle.jbo.Row;

public class DumpRows
{
    private static ADFLogger _logger = ADFLogger.createADFLogger(DumpRows.class);
    public DumpRows()
    {
    }

    public String cb3_action()
    {
        DCBindingContainer bindings =
        (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
        DCIteratorBinding dcIteratorBindings =
        bindings.findIteratorBinding("DepartmentsView1Iterator");

        // Get all the rows of a iterator
        Row[] rows = dcIteratorBindings.getAllRowsInRange();
        for (Row row : rows) {
            String depname = (String)row.getAttribute("DepartmentName");
            _logger.info(depname);
        }
        return null;
    }
}
```
As you do not have the class of line interface build you must get the attributes in their names. Be careful here, because any misspelling is cought only when you run the application.

Value of f: attribute to access in my managed bean

Dear all,

I have the diffulty why this code returns a null value.

In my case, I have a component of iterator and I put an attribute by each iteration

<af:iterator value="#{bindings.employee.collectionModel}" var="row">
     <f:attribute name="empID" value="#{row.empID}"/>
     <af:outputText 
                    value="#{pageFlowScope.myBean.customValue}" id="ot1"/>
</af:iterator>

Now, in my managed bean I wanted to access the attribute I put during each iteration so that
I could format the value of the output text.

But I get null values instead.

public class MyBean{
     public String getCustomValue(){
          String empID = (String)this.evaluateEL("#{empID}");
          //problem empID is always null????
     }
     private Object evaluateEL(String el) {
          FacesContext facesContext = FacesContext.getCurrentInstance();
          ELContext elContext = facesContext.getELContext();
          ExpressionFactory expressionFactory =
          facesContext.getApplication().getExpressionFactory();
          ValueExpression exp =
          expressionFactory.createValueExpression(elContext, el,
          Object.class);
          return exp.getValue(elContext);
     }
}

Any tips?

But, at the end of the iteration we do not do anything so no need to worry about its value and infact scope of line is not valid in the iterator.
The getCustomValue method is called for each iteration, so holds the current line instance.

[ADF, JDev12.1.3] How to set a variable to bind a VO (where clause) in a managed bean?

Hallo,
I have a request based on VO.
The query contains a where clause clause and a bindi variable.
In a managed bean I would like to access the iterator of VO setting the value of the bind variable and read the result.
I found this code it is good start, but I do not know how to set the variable binding.
```
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
DCIteratorBinding iter = (DCIteratorBinding ) bindings.get("MyVO1Iterator");
iter.execute();
```
You kindly help me?
Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.
In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.
Sorry if these questions may seem artificial, but I am a beginner, I have many doubts and so I would be happy to receive some tips regarding best practices.
Thank you
Federico

You can use:
```
iter.getViewObject().setNamedWhereClauseParam("yourBindVar", value);
```
Note that this approach is used if you have bind variable in the where clause.

To set variables bind to ViewCriteria, you must use VarableValueManager.

This post may be useful for you: binary: how to set the Bind variable values at run time?

Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

You must set "use VO directly.

For example, from the point of architecture, is probably best to use the method in the model project which will set the bind variable and execute the query.

Or you can use the ExecuteWithParams operation in your the view layer.

In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

Not to complicate your life

All VO lines are represented as ViewRowImpl class if you already have "custom class".

Finally, you can generate your own ViewRowImpl class if it is necessary for this.

A search criterion and the result as a table in the header. Wanted to bind the result table to bean to access the value of the key

The search criteria and the result is displayed in the table in a group header. I want to get the value of the selected row and analyze the value of Vo in the next page for a variable binding. So I need to manage the value biniding to the bean tbal, but there is no option to bind the table to a bean. So, how can I get the selected value.
Kind regards
K M Krishna.

First tell us your version of jdev, please.

to get to the selected line you need not to link the table to a managed bean. You can for example drag the necessary attributes of the VO on the page and drop them as components of a inputText. the framework then generated the attribute bindings and sets the values of the current row for them. As you do not really need the inputText elements switch to source view (! it is essential!), then remove them. This will eliminate the Visual component, but attribute bindings are stored.

Know you can access the values through their EL or as you get the value of an attribute via it's mandatory.

It seems that the bean was not found. You set in your config adfc. XML or a btf config? Make sure the names of the bean defined in one of the old config files match. Otherwise, check the exact scope of the bean.

Generate PDFS using Managed Bean with custom HTTP headers
Background
Generate a report in various formats (PDF, delimited, Excel, HTML, etc.) using JDeveloper 11 g Release 2 (11.1.2.3.0) when you click on an af:commandButton. See also the version StackOverflow about this issue:

http://StackOverflow.com/q/13654625/59087

Problem
The HTTP headers are sent twice: once by the framework and once by a bean.

Source code
The source code includes:

-Action button
-Managed Bean
-Task flow

Action button
The action of the button:

< af:commandButton text = 'Report' id = 'submitReport' action = "Execute" / >

Managed bean
The managed Bean is relatively complex. The code "responseComplete" get called, however, it does not seem to be called early enough to avoid the framework application writes the HTTP headers.

Substitution of HTTP response header

/**
* Defines the HTTP headers must indicate to the browser that the
* the report must be downloaded (not displayed in the current
* window).
*/
protected void setDownloadHeaders() {}
HttpServletResponse response = getServletResponse();
response.setHeader ("Content-Description", getContentDescription());
response.setHeader ("Content-Disposition", 'attachment filename ='
(+ getFilename());
response.setHeader ("Content-Type", getContentType());
response.setHeader ("Content-Transfer-Encoding',
getContentTransferEncoding());
}

Question answer full
The bean indirectly says infrastructure that the answer is managed (by the bean):

getFacesContext () .responseComplete ();

Bean, run and configure

public void run() {}
try {}
Report = getReport();
Configures (Report.GetParameters ());
Report.Run ();
} catch (Exception e) {}
e.printStackTrace ();
}
}

private void configuration (parameters p) {}
p.put (ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put (ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put (ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put (ReportImpl.SYSTEM_REPORT_PATH, "/ reports/rwservlet" "");
p.put (Parameters.PARAM_REPORT_FORMAT, 'pdf');

p.put ("report_cmdkey", getReportName());
p.put ("report_ORACLE_1", getReportDestinationType());
p.put ("report_ORACLE_2", getReportDestinationFormat());
}

Workflow
The workflow calls Execute, which refers to the 'run()' of the bean method:

entry-> Home-> run-> ReportBeanRun

Where:

<-l' call the method id = "ReportBeanRun" >
< description > running a report < / description >
Report to run < display name > < / display-name >
< method > #{reportBean.run} < / method >
< result >
success of < fixed-result > < / fixed-results >
< / results >
< / method >

The bean is assigned to the scope of the "demand", with a few managed properties:

< rule of flow control = "__3" id >
hand < of-activity-id > < /-activity-id >
< control-flow-case id = "ExecuteReport" >
run < from outcome > < / de-results >
ReportBeanRun < to-activity-id > < / to-activity-id >
< / control-flow-case >
< / control-flow-rule >

< managed-bean id = "ReportBean" >
< description > running a report < / description >
< display name > ReportBean < / display-name >
application of < managed-bean-scope > < / managed-bean-scope >
...
< / managed-bean >

The "success < fixed-result > < / fixed-result > ' strikes me as wrong - I don't want to not the method call to return to another task."

Restrictions
The report server receives requests from the web server only. The URL of the report server cannot use browsers to download directly, for security reasons.

Error messages
The error message is generated:

Duplicate received headers from the server

349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION) error: multiple headers received separate Content-Disposition. It is not allowed to protect themselves against HTTP response splitting attacks. Nevertheless, the report is generated. Prevents the framework to write headers HTTP would solve this problem.

Question
How can define you HTTP headers in ADF using a workflow to generate a PDF file by calling a managed bean?

Ideas

Some additional ideas:

-Substitute the listener of the Phase of the lifecycle of Page ("ADFPhaseListener" + "PageLifecycle")
-Develop a customized web server Servlet

Thank you!
The problem was that the HTTP headers have been actually written twice:

1. the report server returns the HTTP response headers.
2. the bean was his own (as mentioned in the question) HTTP response headers.
3. the bean was copy all the contents of the report server response, including headers, to the output stream.

Firefox has ignored the header in double, but not Google Chrome errors.

Need help for managed bean - to the values of the extraction of data loading of jsf is

Hello
in the construction of managed bean, I wrote code to extract values from database.

but for each action (such as button clicks, drop-down list changes etc...) this constructor is called I don't want.
