How to convert user input on the page in capital letters?

For the experienced:

I use JDeveloper 10.1.3.4 to develop my application.

The application has an Oracle database table named USERS. A column named USER_ID, must be uppercase when recording in the table.

I dragged the create action of the corresponding VO named users to a page to create a commandButton control. When you click this button, the user is navigated to a page "Create an account" to fill in all the fields and save the entry in the USERS table.

On the page "Create a new account", users of VO is slid to the page as a form of the ADF. The action of validation is dragged to the page as the "Save" button. User input is stored in the USERS table as a new row when the user clicks on the button "Save". But what the user types in the user name field can contain lower-case characters. This entry should be converted to uppercase before saved in the USERS table. I tried to convert the setter in the VO or EO, such as:
    public void setUserid(String value) {
        value.toUpperCase();   //I added this line.
        setAttributeInternal(USERID, value);
    }
But this has no effect. Then I tried to make a change similar to the Get accessor method, such as:
    public String getUserid() {
        //return (String)getAttributeInternal(USERID);  // this is original code.
        //What I added:
       String uppperUserid = (String)getAttributeInternal(USERID);
        return upperUserid.toUpperCase();
    }
But I get an error: {color: red} Houston-27019: getting the method for the attribute 'Userid' in users could not be resolved. {color}

Can anyone help? Thank you very much!

  • How do I redirect users always to the page of dashboard in OBIEE 11 g

    Hi all

    I need like that. Whenever a user disconnects and connects to the back the user should see the page of dashboard only.

    Currently I give them a URL such as http://xxxx:29704/analytics/saw.dll?Dasboard when they connect with this URL, they are taken directly to the dashboard page, but, as soon as the user disconnects and connects to the back of the user is redirected to the Home Page (http://xxxx:29704/analytics/saw.dll?BIEEHome) that they shouldn't see.

    specifically, the user should always see the only dashboard pages.

    Any help please...

    Thank you

  • How to convert string input streams

    Can someone tell me how to convert string input streams...

    There are multiple ways. I will list down few of them.

    With the help of the old solution and standard java.

    publicstaticString fromStream(InputStream in)throwsIOException

    {

       BufferedReader reader =newBufferedReader(newInputStreamReader(in));

       StringBuilder out =newStringBuilder();

       String line;

       while((line = reader.readLine()) !=null) {

           out.append(line);

       }

       returnout.toString();

    }

    returnsb.toString();

    If you use Google-Collections/guava-

    InputStream stream = ...

    String content = CharStreams.toString(newInputStreamReader(stream, Charsets.UTF_8));

    Closeables.closeQuietly(stream);

    If you use the common Apache library... then it is worthwhile.

    StringWriter writer =newStringWriter();

    IOUtils.copy(inputStream, writer, encoding);

    String theString = writer.toString();

    Quick way but only work during deserialization.

    String result = (String)newObjectInputStream( inputStream ).readObject();

    Note: ObjectInputStream is on deserialization and the flow of data must respect the Protocol of serialization to work, which may not always true in all cases.

    Ultimately, the most effective solution and only in two lines using java class Scanner.

    Tricky is to remember the \A regex that matches the beginning of the entry. It actually indicates Scanner to mark all of the flow, from start to beginning next (illogical).

    publicstaticString convertToString(InputStream in) {

       java.util.Scanner s =newjava.util.Scanner(in).useDelimiter("\\A"); 

           

       returns.hasNext() ? s.next() :"";

    }

    Hi Barry

    Affecting the security attribute Access Page Protection page No. URL Access and navigate between pages using the type of the Page Management Branch (uncheck the option creates a branch using redirection page in the Wizard) will avoid this:

    No URL access -Page can not be found using a URL, but the page can be the target of a type of Page Management Branch, is not doing a URL redirect.

    It is a little more restrictive that a normal direction of the session state values cannot be positioned or erased declaratively in the branch, but is not often necessary in a several step wizard, and it's pretty simple to work round using prior processes - or post-branche or by referencing the item values directly from other pages.

  • HP laserjet 1022 does not wait for the user to turn the pages when printing double-sided

    My Hp laserjet 1022 printer working properly for years.

    So far, when he executed more paper he tried a couple of times to get more paper and then stops with a message on the PC it is out of paper.

    Very annoyingly, this has changed recently, now when it is out of paper, he tries a couple of times to get more paper and watch the message on the PC, saying that it is paper and then again, try a couple of times to get more paper and again shows the same message on the PC and him back... This continues to go on and on.

    It's especially annoying when trying to print double-sided. Before he used to stop and ask you to turn the pages to print the other side. Now the previous behavior overrides the break to turn the pages and keeps it will try to get more paper. As now, it does not wait for the user to turn the pages, in general it spoils the impression out by getting another paper that is not what I wanted, he drives me crazy! It's really hard to print anything double face now.

    All solutions?

    Operating system is Windows 7, I just downloaded and installed the latest driver for this printer "2013-01-09, Version: 20120918" and I get the same behavior. In the properties of the printer that I put some State Messages to Off and at least I don't get the full windows message screen poping up every time the printer is trying again to get more paper. I have not found all the other parameters that may affect this behavior.

    Help!

    Hello

    I solved the problem! I found the original CD for the printer. I uninstall the current driver and then install CD and now when the printer is out of paper trying to get paper a couple of times and then stops, as it used to be.

    Thanks for your help.

    Hi stupiddonkey,

    You will need to remove the password from the file (using Acrobat, not reader) before you can convert it to Word. To do this, choose file > properties, and then click the Security tab choose no security in the context menu of the security method and enter the password when you are prompted.
