    <p>I am creating web application using JSF 2.0 where I am doing validation for full name.</p> <pre><code>&lt;h:inputText value="#{PersonalInformationDataBean.fullName}" size="75" id="fullName" &gt; &lt;f:validator validatorId="fullNameValidator" /&gt; &lt;/h:inputText&gt; &lt;font color="red"&gt;&lt;br /&gt;&lt;h:message for="fullName"/&gt;&lt;/font&gt; </code></pre> <p>In java below is what I have</p> <pre><code>public class FullNameValidator implements Validator { public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { String enteredName = (String) value; // Pattern p = Pattern.compile("([a-zA-Z]+|[a-zA-Z]+\\s[a-zA-Z]+)"); Pattern p = Pattern.compile("([a-zA-Z\\s]+)"); Matcher m = p.matcher(enteredName.trim()); System.out.println("trimmed data is " + enteredName.trim()); boolean matchFound = m.matches(); if (enteredName.trim().length() == 0) { FacesMessage message = new FacesMessage(); message.setSummary("Please enter name."); throw new ValidatorException(message); } if (enteredName.trim().length() &lt; 10) { FacesMessage message = new FacesMessage(); message.setSummary("Name should be atleast 10 characters."); throw new ValidatorException(message); } if (!matchFound) { FacesMessage message = new FacesMessage(); message.setSummary("Invalid Name."); throw new ValidatorException(message); } // FacesMessage message = new FacesMessage(); // message.setSummary(""); // throw new ValidatorException(message); } } </code></pre> <p>When I run project locally, it runs perfectly.</p> <p>When I took this project online, I am facing problem.</p> <pre><code>++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + fullName data as + Error Message + +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + 123343543534545 + Invalid Name + + fahim + Full name should be 10 characters + + null (blank) + NO MESSAGE, here I was expecting + + + result as Please enter name + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ </code></pre> <p>I don't understand when I don't pass any value, why I don't get error message saying Please enter name. Any idea what I am missing here?</p> <p><strong>Note:</strong></p> <p>I don't even get <code>trimmed data is</code> in <code>catalina.out</code> file where I get all message which I have printed under <code>System.out.println</code></p> <p>The problem is when I pass data at that time only validation is called. Else validation is not happening. Please let me know what I am missing here.</p>

    2. CO@Daniel : If I keep required="true", I get default error as "fullName: Validation Error: Value is required." which I don't want. I want my own messages.

    3. COthan you can use `requiredMessage=""` in your `h:inputText` or override the JSF default message for required field validation (`javax.faces.component.UIInput.REQUIRED`) http://www.mkyong.com/jsf2/customize-validation-error-message-in-jsf-2-0/

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
