The weblayout directory is on a filesystem with 8dot3 semantics. Legacy 16-bit 8dot3 filenames conflict with revision labels and will cause file loss. Disable 8dot3 semantics by running "Installer DisableNtfs8dot3" and then restarting Windows.

Hello Fellas,

Today I'm sharing my learning with you to how to remove this error,

Just follow this process,


On Windows 7, running Installer DisableNtfs8dot3 does not resolve this. You must make the configuration change manually in the Windows registry.


To change the Windows registry, go to the following key:

Then, set the value of the NtfsDisable8dot3NameCreation key to 1. You must restart Windows for the new setting to take effect.

Please note that Oracle Inbound Refinery is supported on Windows 7 in development environments only.

Populate Data to Select One Choice from Bean

Hello Fellas,
Today I'm Sharing my learning to how to populate data to select one choice Programitically

Steps Involded

1. In the managed bean create a property and make its accessor and mutators.

private ArrayList<SelectItem> al=new ArrayList<SelectItem>();

    public void setAl(ArrayList<SelectItem> al) {
        this.al = al;
    }
    public ArrayList<SelectItem> getAl() {
        return al;
    } 

             use javax.faces.model.SelectItem;

2.  put this code in the getter method.

    public ArrayList<SelectItem> getAl() {
        al.add(new SelectItem("x1","India"));
        al.add(new SelectItem("x2","China"));
        al.add(new SelectItem("x3","Sri Lanka"));
        al.add(new SelectItem("x4","Japan"));
        return al;
    }

3 select the component i.e. select one choice  on the page, use it's selectItems component,
   use its value field,  and put this code there.

 <f:selectItems  id="si2" value="#{XBean.al}"/>

Bean

Email Validation in ADF

Hello Fellas,
Today I'm sharing my learning to how to make a custom validation in Oracle JDeveloper,
Create a java class,

Lets take an example to create a e-mail validation,

import java.io.Serializable;

import java.util.regex.Matcher;
import java.util.regex.Pattern;import javax.faces.application.FacesMessage;import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

public class EmailValidator implements Serializable, Validator {

    public EmailValidator() {
        super();
    }
    public void validate(FacesContext facesContext, UIComponent uiComponent,
                         Object object) {
        String value = (String)object;
        if ((value == null) || value.length() == 0) {
            System.out.println("null value found");
            return;
            //System.out.println("null value found");
        }
        //String expression="^[\\\\w\\\\-]([\\\\.\\\\w])+[\\\\w]+@([\\\\w\\\\-]+\\\\.)+[A-Z]{2,4}$";
        String expression =
            "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
        CharSequence inputstr = value;
        Pattern pattern =
            Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
        Matcher matcher = pattern.matcher(inputstr);
        if (!matcher.matches()) {
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
                                                          "Enter the proper Email Id",
                                                          null));
        }
    }
}

Go to faces-config.xml and open validators tab give a meaningful Id like EmailValidator

& class name

in this case it should be EmailValidator(along with the package)

in the input file just write

<af:inputText label="Enter EmailID" id="it1">
<f:validator validatorid="EmailValidator"/>

</af:inputText>

thank you :)
