• ADF 11 g: unable to get the value managed bean

  Hello
  
  I am facing a strange problem in ADF 11 g.
  The backup of my main page bean is known as MainC.java
  From this file, I am setting some parameters in a file called PIn.java (PInis a simple bean with getter and setter methods)
  Code parameter set is running successfully to support bean (MainC.java).
  But when am retrieving data I'm not getting any value.
  
  I tried the same thing by using a java class instead of backing bean, but there, too, the problem is same value sets but not able to recover.
  
  My faces - config.xml is to be entered for the managed - bean PIn.java and I have tried with all eligible scopes for the bean.
  
  Please give pointers to resolve this problem.
  
  Thanks in advance

  SRY... my mistake :-)

  FacesContext context = FacesContext.getCurrentInstance();
  HttpSession session = (HttpSession)context.getExternalContext().getSession(true);
  sessionInstance = (PiV)session.getAttribute("PiV");
  if(sessionInstance == null) {
      sessionInstance = new PiV();
      session.setAttribute("PiV", sessionInstance);
  }
  

  The clause if the new statement was erroneous. It has been created a new body, whose only knews by your method :-) Now your variable overall "sessionInstance" has been completed.

• @EJB does not not for controlled in adfc-config beans

  using adf 11.1.1.3
  
  We have an application that uses the EJB (deployed on the WLS even our application). We notice that when we create beans controlled in the adfc-config and use the @EJB annotation to get an instance of the sessionbean, it does not work.
  
  The error we get is a simple nullPointerexception pointing to the EJB.
  
  When we register the bean in faces - config.xml, instead of the adfc - config.xml, we receive an instance of the EJB.
  I also have a nullpointerException when I add the bean managed a taskflow instead of the adfc-config.
  
  It is an example of the bean:
  

  public class HomeTest {
      
      @EJB
      MyService service;
      
      public HomeTest() {
      }
      
      public List getData(){
        return service.getSomedata();
      }
  }

  When I sign this adfc-config bean I get a nullpointer on service.
  When I join the bean in faces-config, it works.

  Hello

  I think that if the solution is then JSF supports this

  1. use @EJB in a managed bean added to a servlet (application session request) scope in faces-config. XML

  2. in the managed bean ADFc, use EL to resolve access to the bean managed in faces - config.xml and pass the handle of the EJB instance

• 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 String getToUpperCase (String str) {}

  Dim retVal = str.toUpperCase ();

• 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.

• Accesing EJB in an other managed Bean

  Hello

  I just wanted to check.

  When you want to access an EJB that runs on another weblogic managed server, you should always use a PROVIDER_URL pointing to the t3 of the managed server protocol.

  Fix?

  Hello

  Yes. You will need to provide the url property provider to search for a remote bean.

  Java.naming.Provider.URL = t3: / /:

  /*

  Hashtable env = new Hashtable();
  env.put (Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");

  env.put (Context.PROVIDER_URL, "t3: / /:" "");

  InitialContext context = new InitialContext (env);

• 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.

• How to call separate partial trigger on managed bean JSFF component?

  Guys and girls,
  
  With the help of JDev 11.1.1.2.0. Looked on the forums and google. The first results are not so large.
  
  Is it possible to call a PPR on a component JSFF from a separate managed bean? He seems to call the FacesContext in this instance calls the JSPX root that contains only a child: the RichDocument.
  

        UIComponent component =
           FacesContext.getCurrentInstance().getViewRoot().findComponent("pc1:table1");
        if (component != null)
        {
           AdfFacesContext context = AdfFacesContext.getCurrentInstance();
           context.addPartialTarget(component);
        }

        System.out.println(FacesContext.getCurrentInstance().getViewRoot().getChildCount());

  Returns 1 :(
  
  Ideas for a workaround?

  Hello

  You can do this using the FacesMessage class and this can be written anywhere within action/actionlistener/valuechangelistener/post etc...

  Example Code:

  //adding global message, which is displayed with af:messages tag
  FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "Value entered is invalid");
  context.addMessage(null, msg);  
  
  //Component level message, need to use af:message tag. This component level message is also displayed under af:messages tag unless globalOnly property is set to true

• [Q] how to build and install an SSL certificate signed for the management of a Cisco 5508 WLC?

  Our security policy requires that all web pages admin must be signed by our CA business. I have successfully implemented a SSL certificate 3rd party Auth Web our WLAN of comments, but I need to install a self-signed certificate for the management of the WLC himself. I followed the instructions here:

  http://www.Cisco.com/en/us/Tech/tk722/tk809/technologies_configuration_example09186a00806e367a.shtml

  but it was more useful for Web auth. I can't find a specific document explaining how it should be done for the management interface.

  Any help much appreciated.

  (1) Please use a password. Empty passwords regularly give problems.

  (2) you don't recombine the key with the certificate before you download to the WLC:

  Combine the CA.pem certificate with the private key, and then convert the file to a .pem file.

  Type this command in the OpenSSL application:

  openssl>pkcs12 -export -in CA.pem -inkey mykey.pem -out CA.p12 -clcerts
  
      -passin pass:check123 -passout pass:check123
  
      
  
      !--- This command should be on one line.
  
  
      openssl>pkcs12 -in CA.p12 -out final.pem -passin pass:check123 -passout pass:check123
  
      

  Note: In this command, you must enter a password for the parameters -passin' and -passout . The password is set to the setting -passout must match the setting SubscriptionId is configured on the WLC. In this example, the password is configured at the time the -passin' and settings -passout is check123. Step 4 of the procedure in the section download the WLC third certificate of this document deals with the configuration of the SubscriptionId parameter.

  The final.pem is the file that is transferred via TFTP to the Cisco WLC.

  Now that you have the certificate of the third-party CA, you must download the certificate to the WLC.

• 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)
