Workflow managed bean with dynamic class

Hello
I am trying to create an Adaptive workflow, which is generic and can be reused. The problem I have is trying to define the bean managed support. Ideally I'd like a different class of bean to be used in various circumstances, but with the same name. I don't know what class to use until the output of the task is called.
I can't use for EL do know
```
<managed-bean id="__1">
  <managed-bean-name>RegionBacking</managed-bean-name>
  <managed-bean-class>${pageFlowScope.regionBackingClass}</managed-bean-class>
  <managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>
```
(regionBackingClass is a java.lang.String parameter passed in the taskflow with the class path).
At this point, I need to use different classes have the same method names in their breast, just different code in methods, but that could change in the future.
Thank you.

Hello

use a model approach. The managed bean configured as managed bean is simply a wrapper and instantiated dynamically the class that you want to manage the logic. Thus, you can for example pass the class name as input argument for the workflow in the managed bean and admire you the name then create the instance of the class to send all requests to.

The flow of work, Servlet, popup and a managed Bean validation

Hello

We try to display a PDF file in a pop-up window by calling a Servlet in a JSF page using a workflow in JDeveloper 11 g R2.

The relevant part of JSF:

<af:inlineFrame id="if1" shortDesc="Report" source="/pdfservlet" styleClass="AFStretchWidth"></af:inlineFrame>

The /pdfservlet points to a Servlet with a method doGet as follows:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  response.reset();
  
  OutputStream out = response.getOutputStream();

  FacesContext context = this.getFacesContext(request, response);
  OracleReportBean bean =
    context.getApplication().evaluateExpressionGet(context, "#{reportBean}", OracleReportBean.class);

  bean.run(context, out);
  removeFacesContext();

  out.close();
}

The Servlet is trying to get the FacesContext, but we met with the following exception:

Caused By: javax.faces.FacesException: Cant instantiate class: oracle.adfinternal.view.faces.component.AdfViewRoot.

We have removed the following lines to the getFacesContext() method:

UIViewRoot view = facesContext.getApplication().getViewHandler().createView(facesContext, "");
facesContext.setViewRoot(view);

This avoids the exception above, however... We try to get the settings of the form that was submitted. Here is an example of the form element:

<h:inputHidden value="MyMedicationList_Report" id="system_REPORT_RESOURCE"/>

When the Servlet calls the Bean managed to retrieve the value, it uses:

Map<String, String[]> requestParameters = getRequestParameters();
Parameters p = getParameters();

for( String key : requestParameters.keySet() ) {
  for( String value : requestParameters.get( key ) ) {
    int i = key.indexOf( ':' );

    if( i >= 0 ) {
      key = key.substring( i + 1 );
    }

    p.put( key, value );
  }
}

Where getRequestParameters() tries to get the external context to retrieve the map of query parameter values:

return getExternalContext().getRequestParameterValuesMap();

The card is empty.

I tried after http://www.oracle.com/technetwork/developer-tools/adf/learnmore/oct2010-otn-harvest-183714.pdf by assigning the web.xml file:

  <!-- JspFilter must be configured before adfBindings. -->
  <filter-mapping>
    <filter-name>JpsFilter</filter-name>
    <servlet-name>PDFServlet</servlet-name>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>REQUEST</dispatcher>
  </filter-mapping>
  <filter-mapping>
    <filter-name>adfBindings</filter-name>
    <servlet-name>PDFServlet</servlet-name>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>REQUEST</dispatcher>
  </filter-mapping>

And set the data bindings on:

  <pageMap>
    <page path="/pdfservlet" usageId="ca_bcpra_promis_reporting_view_PDFServletPageDef"/>
  </pageMap>
  <pageDefinitionUsages>
    <page id="ca_bcpra_promis_reporting_view_PDFServletPageDef" path="ca.bcpra.promis.reporting.view.PDFServletPageDef"/>
  </pageDefinitionUsages>

The Servlet is running, called the managed bean instantiated, but cannot read the query parameters.

Is the button used to start the workflow in a dialog box:

<af:commandButton text="Run Report" id="submitReport" useWindow="true"
                  windowEmbedStyle="inlineDocument" windowModalityType="applicationModal" windowHeight="500"
                  windowWidth="700" action="runReport"/>

By using a workflow, the user input are validated before the opening of the pop-up window. We want to keep this behavior. The PDF file opens and then returned with a NullPointerException:

http://pastebin.com/raw.php?i=PaM64jL4

The Servlet, through the managed bean, made a request to the report server to pass parameters and generate a PDF file. The PDF is sent to the browser via the Servlet.

What other steps can we take to:

1. send user and system parameters.
2. generate a PDF file on a remote server.
3 distribute the PDF file to the user in a pop-up window.

Thank you.

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.

JDeveloper 11 g managed bean & resource bundle mysteries
Hello

I literally fight JDeveloper to make the location of my application. I want to set the locale of all my pages to a value of a managed bean (which gets the database for all users), so I put < f: view local = "#{Configuration.language}" > and get all the labels and strings in my UI to a resource group.

Two issues were raised:

1. I created a bean managed and recorded as 'Configuration' in faces-config. XML with scope. The managed bean is a private channel 'language' with accessors. When I use the "expression builder" on any page, it creates the following expression: "#{applicationScope.Configuration.language}". Unfortunately, it returns nothing. Manual change of the expression "#{Configuration.language}" finally returns! Why isn't he created like this by the generator expressions in the first place? I did sth. evil?

2. I created a resource 'view.resources.UIresources' group and registered as "res" in faces - config.Xml. reference manually as #{res ['arbpl.titel ']} works fine. When the regional settings of the page are changed, strings are loaded from the appropriate resource bundle. As there is a lot of hits, I would use the wizard 'Select a resource text' or enter the values directly in the designer.

However, the Assistant to "Select a text resource" refers to some crazy #{viewcontrollerBundle ['arbpl.titel']} and add "< c:set var ="viewcontrollerBundle"value="#{adfBundle['view.resources.UIresources']}"/ >" under the jsp:root. What is everything? The problem is that this way always the default resource group appears to be responsible no matter what locale are defined in the f: view.

Who can help me see clear here?

Thank you
Matt
Matt,

Step 1 - really think you so that it is within reach of the session - if it is different for each user, it should be.

In addition, on the generator, you are using the node called JSF managed Beans and navigate directly on your beans?

Using @Interceptors with ADF managed beans

Hi Experts,
I am using the annotation javax.interceptor.Interceptors on my methods of ADF managed beans, but my methods of interception are not get called.
Is it possible to use it with controlled beans? Has anyone tried this before?
JDev: 11.1.1.7
Java: 1.7
MyInterceptor.java
=========
public class MyInterceptor {}
public MyInterceptor() {}
Super();
}
@AroundInvoke
public object intercept (InvocationContext context) throws Exception {}
System.out.println ("MyInterceptor - logging BEFORE calling method:"+ context.getMethod () .getName () ");
Object result = context.proceed ();
System.out.println ("MyInterceptor - logging AFTER calling method:"+ context.getMethod () .getName () ");
return the result;
}
}
=========
SomeBean.java
=============
public class SomeBean {}
@Interceptors (MyInterceptor.class)
{} public void doReset (ActionEvent actionEvent)
do something
System.out.println ("In reset");
}
}
=============
Thank you
Soham

As far as I KNOW, JSF(and ADF) can't stand the interceptors.

Maybe you can try this in 12.2.1 jdev because with this version is packaged 2.2 JSF (which should support the CDI)

How to call a function with parameters in jsf managed Bean

Hello
1. I created a Bean managed to manage chains of jsf to 11.1.1.7 WebCenter spaces:
public class ManageStrings {}
/ * Converts all characters in a string to uppercase. */
public String getToUpperCase (String str) {}
Dim retVal = str.toUpperCase ();
Return retVal;
}
}
2. I registered managed Bean:
" < managed-bean id ="swc_3"xmlns =" http://xmlns.Oracle.com/ADF/controller "> "
< id managed-bean-name = "swc_2" > tools < / managed-bean-name >
< managed-bean-class id = "swc_1" > cat.badalona.webcenter.utilities.ManageStrings < / managed-bean-class >
< managed-bean-scope id = "swc_4" > backingBean < / managed-bean-scope >
< / managed-bean >
3 to code jsf, I tried different options, but they do not work
" < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value="#{backingBeanScope.utilities.getToUpperCase['hello']}"/ > "
...
" < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value="#{backingBeanScope.utilities.toUpperCase['hello']}"/ > "
..
" < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value =" #{backingBeanScope.utilities.getToUpperCase ('hello')} "" / >

What I am doing wrong?

Thaks in advance

Hello Carles,

I did it with the content presenter where I need to pass the ID of the component selected in backing bean. Please try below option

Now add following code in your binding

Private RichOutputText outputText1;

then the getter for this outputtext set.

and in your action method to read the value of the output text.

Hope this helps with your problem.

Thank you

Blog of Ashish Awasthi (Jdev/ADF): extended memory for ADF Managed Beans - according to the directives of the Fusion developer's guide

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.

UTF-8 problem with ADF

But this solution is for the JSPX pages:

< jsp:directive.page contentType = text/html"; Charset = UTF - 8 "/ >

How can I solve this problem for ADF 12 c + JSF pages / Fragments of JSF Page. ?

It should work.

Check the compiler settings in the project properties (and also check: Tools-> preferences...-> environment)

Also check the encoding in the file pageDef (if you have one).

[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.

Several fragments of the page pointing to the same managed bean

I wanted to know if we can point to several jsff developed o your managed bean?
While I'm trying to do, I don't get the option to create a new property or use an existing property of the bean while creating a link.
Is this possible, if so what should be the scope of these beans.

Hi Ashish,

The field itself has been disabled for me, what I did was save the bean in the scope of the Session in the config of the adfc. Now its working fine for me.

How to use the trigger in the doDML?

You cannot use db trigger, but you can implement the logic of your trigger, something like:
```
protected void doDML(int operation, TransactionEvent e) {
if(operation==DML_INSERT)
  BigDecimal yourSeq = new SequenceImpl("Learner_seq",getDBTransaction()).getSequenceNumber();
  java.util.Date  sysdate = new java.util.Date();
  SimpleDateFormat  sdf = new SimpleDateFormat("yyyyMM");
  String yourStudentNo = sdf.format(sysdate) + yourSeq.toString();

  this.setStudentno(yourStudentNo);
}

super.doDML(operation, e);
}
```
And in your bean you can retrieve the value of the current row.

One of your previous answers, something like:

AttributeBinding attrStudentno = (AttributeBinding) bindings.getControlBinding ("Studentno");

String studentNo = (String) attrStudentno.getInputValue ();
