How to get to variable in backing_bean from java code

I need to reach one of my variable in a backing_bean of java code (when click the button I need to get the value of the variable is on one of the backing_bean)
I have defined the field of beans as session
what I need to do

Copy the following code in my bean

private String loginType.

public String cb2_action() {/ / I call this method}
setLoginType ("skip");
}

and in this method, I try to get the value of the parameter

public String getLoginType() {}
FacesContext fctx = FacesContext.getCurrentInstance ();
ELContext elctx = fctx.getELContext ();
Application = fctx.getApplication ();
ExpressionFactory exprFactory = application.getExpressionFactory ();
ValueExpression valueExpr =
exprFactory.createValueExpression (elctx, "#{bindings.loginType.inputValue}", Object.class);
oracle.jbo.domain.Number departmentId = null;
loginType = (oracle.jbo.domain.Number) valueExpr.getValue (elctx);
"" return loginType + ' ";
}

When I run the code it returns null

so, in this case... Set the connection type in a sessionscope... and access it anywhere...

            Map sessionMap = (Map)ADFUtils.evaluateEL("#{sessionScope}");
            sessionMap.put("loginType",loginTypeValue); // loginType value is set here..

//access it outside like
            Map sessionMap = (Map)ADFUtils.evaluateEL("#{sessionScope}");
           sessionMap.get("loginType");

  • PowerCLI Invoke-VMScript re - ip guest - how to get the variable hostname comments

    I run the following script as a task Post-Power-we a re - ip our VMs after that MRS. them rocking.  I was able to run this script successfully without the variable hostname of comments (in the test, he runs a script by test VM with the hostname assigned...), but I'm stumped on how to get comments variablized according to the machine's host name works on, it will take the host name and use it in the GuestUser variable and the command - VM.  I tried the bold part, but it does not work.

    Thank you!

    How you code the - VM on the Invoke-VMScript cmdlet parameter, it seems that Displayname of the guest is the same as the host name.

    Can't you just use a loop on guests and then use the displayname property

    $script = "%windir%\system32\cmd.exe /c c:\dr\drIPsettings.bat"
    $HostUser = "root"
    $HostPassword = "password"
    $GuestPassword = "password"
    $ScriptType = "bat"
    
    Get-VM | %{
       $GuestUser = $_.Name + "\Administrator"
       Invoke-VMScript -ScriptText $script -VM $_ -HostUser $HostUser -HostPassword $HostPassword -GuestUser $GuestUser -GuestPassword $GuestPassword -ScriptType $ScriptType
    }
    

    You can encode the Get - VM with more specific selection criteria or use a Where-Object after the Get - VM.

  • How to simulate BlackBerry options/commands from java code?

    Hi friends,

    For wipe/erase of personal data, we have the following option on BlackBerry phone (model: 9930)
    Options of-> Security-> Security Wipe

    I want to give the same option in my BlackBerry App (e.g.. A button marked "clear data")
    How can I simulate the same functionality through java code

    Can someone please provide some help or provide a reference to the entire API

    Thank you

    Laughing out loud
    You can enter simulation (clicks, presses), and you can launch native applications, if you know their module name, but both approaches have their limitations.

    See http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/system/ApplicationManager.html... or http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/system/ApplicationManager.html... to see how to apply.

  • How to create a BPEL Process task using java code

    Hello

    I created a BPEL process (for creating task), in which my requirement is that I need to create a task based on some inputs and assign it to the user in partucular and then get out of this flow.

    earlier, I felt that I will use the human task activity. but when I use that task will be created in the same process and proceedings will be stuck on there until human intervention (the BPEL process waits for the result.).

    is it possible that I can use Java activity and create tasks from java code, 'I know how to assign a specific user task. Please tell me.

    Published by: abhishek on April 25, 2011 12:42 AM

    Hi Abhishek
    1. you can try this alternative approach and it should work.

    2. basically, most of the BPEL process eventually auto generated Web services (.) WSDL). When we create a BPEL process, everything we do is give diagram of input, output schema and creates a bpel process with the default operation named as "process" in all the old versions as up to 11.2 SOA (and maybe before). BUT SOA 11.3 from, we can create a process BPEL, with our own WSDL and our own scheme. There is no restrictions like having only a single operation named 'process', etc.. In any case, what I mean is, each BPEL process ends up as a WebService, with entry and exit of the payloads of XSD.

    3. from the JDeveloper itself, locate the .wsdl for your BPEL process under the Workflow project. Create a new project of Proxy customer service Web and generate a customer for this wsdl Web service proxy. This will create you Service, Port and JAVA classes equivalent payload theoretically in your case taskpayload.xsd with these 4 items you have. Ignore the full blown the HumanTask which has all the system elements and attributes of a task of bpel. All you need is to undertake a task with your own payload data. Create a simple Client Java (EJB or Servlet later to make more flexible). In this Java client, retrieve the Service object in the proxy and port. Then instantiate the java class that represents the payload. Set 4 values you want and set the user name, etc. You may need some adjustments for the setting of the user. Then the port invoke otherwise (go your java object here).

    Sample code snippet
    prepare the message for BPEL of appeal; Define the fields that can not be null
    MyPayloadRequest myPayloadRequest = new MyPayloadRequest();
    myPayloadRequest.setInitiator("");
    myPayloadRequest.setTitle("");
    myPayloadRequest.setEmployeeName("");
    myPayloadRequest.setEmpContact("");

    web service client Get for BPEL receive point and call: first generate client proxy
    MyBPELPProcess_client_ep serviceClient = new MyBPELPProcess_client_ep();
    MyBPELPProces proxy = serviceClient.getNewMyBPELPProces_port ();
    proxy. Process (myPayloadRequest);

    Please note that you can also use the SOA workflow API and the Manager back call personalized for this first task classes. In this class, you can have the methods of the interceptor, which is called each time a task is initiated, saved, Submit, approve etc etc (all events essentially). This gives you access to all the objects in a workflow with full charge blown. So you can always get the data you pass above and in this custom class, the value of the user, date/time etc..

    It's just a different approach you can try.

    Thank you

    String tttValue = map.get('zoom') ("test");
    System.Err.println ("test:" + tttValue);
    Returns a null value.
    }

    but it does not work... Whenever I get nothing when I click on the button. Could you tell me why and how to get the value of InputTex in my java function?
