• Read each name in Array list to create seperate object for

  I have a file that has student names, age, and an id number. I have a student class that holds the everything above for each student object. I stored all the names, id numbers. and age separately in an array list. Now im trying to assign the info to create a student object.

  public class Student {
      private String lName;
      private int idNumber;
      private int age;
  
      public Student() {
          lName = "";
          idNumber = 0;
          age = 0;
      }
      public Student(String l, int i, int a) {
          lName = l;
          idNumber = i;
          age = a;
      }
  
      public void setName(String last) {
          lName = last;
      }
  
      public String getName() {
          return lName;
      }
  
      public void setIdNum(int num) {
          idNumber = num;
      }
  
      public int getIdNum() {
          return idNumber;
      }
  
      public void setAge(int a) {
          age = a;
      }
  
      public int getAge() {
          return age;
      }
  }
  

  My Text File looks something like this: This info is stored in parallel array lists. I don't quite get how to implement this into an object to pass it into my second contractor method.

    Josh          2134         19
    Smith         5256         21
    Rogers        9248         19
    Andrew        7742         20
  

  Here's what I've tried;

  public static void main(String[] args) {
      String file = "studentData.txt";
      Scanner reader = new Scanner(file);
  
      ArrayList<String> lastNames = lNames(file);
      ArrayList<Integer> idNumbers = idNum(file);
      ArrayList<Integer> ageList = ages(file);
  
      Scanner input = new Scanner(System.in);
  
      Student s1 = new Student();
  
      // confused about how to implement this constructor with the textile info
      for (int i = 0; i<idNumbers.size(); i++) {
          Student user = new Student(lastNames.get(i), idNumbers.get(i), ageList.get(i));
      }
  
      //user enters idNumber to display age
      System.out.println("Enter ID Number"); //exception handling to be added
      int idNum = input.nextInt();
  
      for (int i = 0; i<idNumbers.size(); i++) {
          if (idNum == idNumbers.get(i)) {
              s1.setAge(ageList.get(i));
              System.out.println(s1.getAge());
  
          }
      }
  }
  
• Using EdittextPreference for Goto search

  sorry for my poor English. I want to use EditTextPreference in my bottom nav like the pic below, ![screenshot][1]

  I have recycleview xml in my project with in many sub cardview layouts(which is scrollable) and I want to create item in the bottom nav which is called "Goto". When the "Goto" item is clicked i want it to pop-up like the screenshot. And when user enters a number(according to the cardviews i.e if the number of cardview is 40 user must enter 1-40) I want to search the cardview by its ID. Thank you and I hope u got it, If u have any questions let me know [1]: https://i.stack.imgur.com/grK8P.jpg

  My xml format look like this. As you see in the blow since the cardviews are huge in number it is not cool to scroll all the way down that is why i need Goto item in the bottom nav to search it by its ID when the user click number in the EditTextPreference as u see in the screenshot. i.e The screenshot is not from my app

• Hibernate handles id assigning instead of database

  I have an auto-increment PK in a table and I want hibernate to handle id assigning instead of database. As my understanding the @GeneratedValue(strategy = GenerationType.IDENTITY) lets the database generate a new value with each insertion operation. So do we have any different solution to handle it?
• How can I delete a row by its SKU instead of its ID?

• JSF 2.2 (Mojarra) calls f:ajax twice in nested composite:component

  i've got a pretty simple example:

  there is a nested composite component.

  on my index.xhtml is a component called "ht:wrapper" to which are registered some ajax listeners for onKeyup and onChange events.

  the compostite component "ht:wrapper" itself provides some clientBehaviors for given events and a nested compostite component "ht:input" this inner component is a simple h:inputText with clientBehaviors registered for keyup and change.

  the ajax listener on index.xhtml will call a javascript function which adds the name of the event ("onKeyup" or "onChange") to a at the bottom of the input.

  my problem: "onKeyup" fires twice if i press/release a single button.

  is this a bug or im i dooing something wrong?

  some tests with myfaces 2.2 seems to work as expected and fires only one event at a time.

  here my minimum example:

  index.xhtml

  <h:form id="htmlForm">
      <p>
          This is a simple example how a behavior (keyup, change) gets called twice. <br /> 
          A simple h:inputText is nested in a composite component,
          which provides clientBehaviors.
      </p>
  
      <ht:wrapper
          id="htmlWrapper"
          value="#{myBean.htmlString}">
          <f:ajax
              event="onKeyup"
              onevent="add('onKeyup')" />
          <f:ajax
              event="onChange"
              onevent="add('onChange')" />
      </ht:wrapper>

• Problems with the attribute "placeholder" of an <p:inputText tag when the value of the inputText is empty

  I am using JSF Mojarra 2.3.9.SP02 with PrimeFaces 7.0 running on Wildfly 17 with the PrimeFaces's own Sapphire template.

  I have a severe problem with one <p:inputText element in my form, for which I have specified a placeholder, and whose initial value is empty. This is the first input field just below the panel group with the title "Kontaktperson" as shown in the attachment

• When nesting another datatable in rowexpansion, splitbutton stops working when 2 or more main rows are loaded

  So I'm trying to nest a datatable within another datatable in the rowexpansion tag as follows:

  <h:form>
      <p:dataTable var="item" 
                   value="#{bean.items}">
          <p:column>
              <p:rowToggler/>
          </p:column>
          <p:column headerText="Item Name">
              <h:outputText value="#{item.name}"/>
          </p:column>
          <p:rowExpansion>
              <p:dataTable var="subitem" 
                           value="#{item.subitems}">
                  <p:column headerText="Subitem Name">
                      <h:outputText value="#{subitem.name}" />
                  </p:column>
                  <p:column>
                      <p:splitButton value="Save" action="#{bean.save}">
                          <p:menuitem value="Update" action="#{bean.update}"/>
                          <p:menuitem value="Delete" action="#{bean.delete}"/>
                      </p:splitButton>
                  </p:column>
              </p:dataTable>
          </p:rowExpansion>
      </p:dataTable>
  </h:form>
  

  the testing methods in the bean are just

      public void save() {
          addMessage(FacesMessage.SEVERITY_INFO, "Success!", "Saved subitem");
          PrimeFaces.current().ajax().update(":frmTopbar");
      }
  
      public void update() {
          addMessage(FacesMessage.SEVERITY_INFO, "Success!", "Updated subitem");
          PrimeFaces.current().ajax().update(":frmTopbar");
      }
  
      public void delete() {
          addMessage(FacesMessage.SEVERITY_INFO, "Success!", "Deleted subitem");
          PrimeFaces.current().ajax().update(":frmTopbar");
      }
      public void addMessage(FacesMessage.Severity severity, String summary, String detail) {
          FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(severity, summary, detail));
      }
  

  If only a single item and its subitems is loaded, everything displays and splitbutton buttons work fine.

  The bean just sends a FacesMessage to test and like I said, the message is properly shown for each of the 3 buttons.

  But as soon as I load 2 or more items and their subitems, everything looks visually correct, but the commands in splitbutton no longer reach bean, so no FacesMessage is sent.

  Does anyone have a clue about what is going on or a suggestion as to what can be done to fix it?

  I'm using primefaces v11.0

  Thanks a lot!

  Today, I have finally managed to replicate this error locally. It happens when you have two tabs open, with one of the tabs having an old, invalidated session id.

  Steps to reproduce this:

  1. Open tab 1 and login to our application.
  2. Wait for tab 1's session to invalidate.
  3. Open tab 2 and login to our application.
  4. Go to tab 1 and do any ajax operation.
  5. Page crashes with the error above.

  We use JSF 2.2 in Wildfly 10.1.0 (Mojarra 2.2.13) and make use of saving our state on the client side. Session id is in the cookie.

  I think that in step 4, the ajax request uses the newer session and thus the user is deemed as logged in. Then it attempts to rebuild the view state on the backend, but fails to do so. I think it's because the view scoped beans have been destroyed when the old session got invalidated.

  Is there a way of detecting this in my code? Preferably in a Http request filter, where I could redirect the user to the home page?
• JSF ajax call giving error within openfacess library - JBoss 7.4 and Java 11

  I'm deploying a web application(war file) to JBoss 7.4 server environment.

  JBoss EAP 7.4.0.GA (WildFly Core 15.0.2.Final-redhat-00001) starting
  

  Java Version

   java.home = /usr/lib/jvm/java-11-openjdk-11.0.14.0.9-1.el7_9.x86_64
  

  This web application uses Mojarra 2.3.14 + Richfaces 4.5.4 + Openfaces 3.0 libraries for some of the UI screens.

  The application was running fine on JBoss 7.1/Java 8. After upgrading to JBoss 7.4/Java 11 any Ajax call on UI screen is giving below error in server log file. There were no change to JSF related libraries.

  The below error is from Openfaces 3.0 library.

• How to send Authorization header in JSF - Mojarra - PrimeFaces

  We have a java 8 project with JSF Mojarra implementation with PrimeFaces 3.5. We are implementing the authentication OIDC using Spring Security.

  The front has to include in each HTTP Request the header Authorization with the bearer token. We couldn't find how to add a header in a call any Primefaces component (commandbutton,etc).

  When I use for example the commandLink tag (https://www.tutorialspoint.com/jsf/jsf_commandlink_tag.htm) I need that the rendered method mojarra.jsfcljs to send the Authorization header with my token when it calls the backend.

  Is there any way of send customized headers with Mojarra in order to implement OIDC protocol?
