Getter method being called twice

Hi All,
I have a h:inputText which updates a h:dataTable as soon as the user types something into it (through the use of Ajax4JSF's a4j:support element). In this way I have something similar to a suggestionbox, but which modifies the table underneath rather than displaying a dropdownlist with possible values. My problem is that for some reason the getter method in the managed request-scoped bean to which the h:dataTable is bound, is being called twice everytime a letter is typed into the h:inputText. The first call seems to happen directly after the bean has been constructed, as the value to which the h:inputText is bound is still empty, and the second call after that, but with the correct value obtained from the h:inputText.
I searched the forums and found posts detailing similar problems, but I couldn't find an explanation of why it happens or a way to get rid of it. The common consensus seems to be to not have any processing intensive operations in the getter and to just accept that it will be called twice.
Is there really no way around this?
Thank you,
Ristretto

This is just the default behaviour of the JSF lifecycle. The first call checks if there is a default value or a value which is been set in the previous request. The second call gets the newly set value for display which is been set during the request processing. A way to get rid of the first call might be writing your own lifecycle implementation.

Servlet doPost being called twice

Hello all,
I have a servlet that is being called twice. The servlet is used to direct the user to the next jsp. I have 4 JSPs that the user steps through to add a record to a database. The 1st JSP lists the records that they have and asks them to add, edit or delete. The servlet gets call to direct them to the next JSP that they enter the data (or update) on. It then calls a verification JSP so the user can verify the information before submitting it. If everything is fine they submit the data. This verification JSP calls the servlet that adds or updates the record in the database. The servlet then directs the user to a confirmation page that tells the user if the submit was successful or not.
Here is how the flow is:
servlet -->menu.jsp -->servlet -->add.jsp -->verification.jsp -->servlet -->confirmation.jsp
Everything is fine until the verification.jsp submits to the servlet. That's where the doPost gets called twice.
I have put System.outs in the servlet code to see how many times the doPost gets called. It gets called once for every JSP except the verification JSP. When the user submits the data, the servlet's doPost gets called twice therefore it tries to add the record twice.
Has anyone had this problem before? How do I fix it?
Any help would be greatly appreciated!!
Tracey

Here is the output of the JSP that when submitted, calls the doPost twice:

How To Ask Questions The Smart Way

Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

Controller Is Being Called Twice - Why???

I think this is going to be a complicated question to answer but I'll try to explain what's going on as best I can. The basic problem I'm having is that the controller class gets called twice for some reason (instead of once) and I have no idea why. I type in a URL in my browser that goes to a JSP page called �myJsp.jsp�. Basically all that page contains is this...
<tiles:insert definition =�my.tile� flush=�true�/>In my tiles-defs.xml file I have the following listing...<definition
name="my.tile"
path="SomeOtherJsp.jsp"
controllerClass="x.y.z.MyController">
</definition>
x.y.z.MyController.java makes some calls to a DAO to retrieve data. MyController.java then puts that data into the requestScope for the JSP below to access...
SomeOtherJsp.jsp has nothing special in it although it DOES contain a link to myJsp.jsp (and, somehow, it's like this link is being clicked even though I'm not clicking it).
<a href="myJsp.jsp?someParam=<c:out value="${requestScope.someValue}"/>">Click Here To Do Something</a>If anyone can help I'd greatly appreciate it. By the way, I spoke to someone else who mentioned that I should turn this kind of thing into a struts action instead of doing a deletion within a controller class. I am going to refactor my code to do this. However, I'm still curious to know the answer to my question. Maybe it will help me get a better understanding of exactly what's going on in the world of servlets. :)

Finalize() method being called multiple times for same object?

I got a dilly of a pickle here.
Looks like according to the Tomcat output log file that the finalize method of class User is being called MANY more times than is being constructed.
Here is the User class:
package com.db.multi;
import java.io.*;
import com.db.ui.*;
import java.util.*;
* @author DBriscoe
public class User implements Serializable {
    private String userName = null;
    private int score = 0;
    private SocketImage img = null;
    private boolean gflag = false;
    private Calendar timeStamp = Calendar.getInstance();
    private static int counter = 0;
    /** Creates a new instance of User */
    public User() { counter++;
    public User(String userName) {
        this.userName = userName;
        counter++;
    public void setGflag(boolean gflag) {
        this.gflag = gflag;
    public boolean getGflag() {
        return gflag;
    public void setScore(int score) {
        this.score = score;
    public int getScore() {
        return score;
    public void setUserName(String userName) {
        this.userName = userName;
    public String getUserName() {
        return userName;
    public void setImage(SocketImage img) {
        this.img = img;
    public SocketImage getImage() {
        return img;
    public void setTimeStamp(Calendar c) {
        this.timeStamp = c;
    public Calendar getTimeStamp() {
        return this.timeStamp;
    public boolean equals(Object obj) {
        try {
            if (obj instanceof User) {
                User comp = (User)obj;
                return comp.getUserName().equals(userName);
            } else {
                return false;
        } catch (NullPointerException npe) {
            return false;
    public void finalize() {
        if (userName != null && !userName.startsWith("OUTOFDATE"))
            System.out.println("User " + userName + " destroyed. " + counter);
    }As you can see...
Every time a User object is created, a static counter variable is incremented and then when an object is destroyed it appends the current value of that static member to the Tomcat log file (via System.out.println being executed on server side).
Below is the log file from an example run in my webapp.

It really does seem to me like finalize is being called multiple times for the same object.
That number should incremement for every instantiated User, and finalize can only be called once for each User object.
I thought this was impossible?
Any help is appreciated!

Thanks...
I am already thinking of ideas to limit the number of threads.
Unfortunately there are two threads of execution in the servlet handler, one handles requests and the other parses the collection of User objects to check for out of date timestamps, and then eliminates them if they are out of date.
The collection parsing thread is currently a javax.swing.Timer thread (Bad design I know...) so I believe that I can routinely check for timestamps in another way and fix that problem.
Just found out too that Tomcat was throwing me a ConcurrentModificationException as well, which may help explain the slew of mysterious behavior from my servlet!
The Timer thread has to go. I got to think of a better way to routinely weed out User objects from the collection.
Or perhaps, maybe I can attempt to make it thread safe???
Eg. make my User collection volatile?
Any opinions on the best approach are well appreciated.

On Execute operation, the bean getter is being called multiple times

Hi,
I have a JCR data control, i am trying to write a method that returns predicate, but this method is being called multiple times, when executing the advanced search operation.
public List<Predicate> getPredicates() {
ArrayList<Predicate> predicates = new ArrayList<Predicate>();
   // predicates.add(new Predicate("jcr:content/idc:metadata/idc:xScope",Operator.EQUALS,"GLOBAL"));
DCBindingContainer bc=(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
JUCtrlListBinding attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("StateId");
Object stateId= attrBinding.getSelectedValue();
if(stateId instanceof Row){
predicates.add(new Predicate("jcr:content/idc:metadata/idc:xState"
, Operator.EQUALS
,((Row)stateId).getAttribute("StateId").toString()));
attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("DistrictId");
Object districtId=attrBinding.getSelectedValue();
if(districtId instanceof Row){
      predicates.add(new Predicate("jcr:content/idc:metadata/idc:xDistrict",Operator.EQUALS,((Row)districtId).getAttribute("DistrictId").toString()));
    attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("Scope");
    Object scopeId=attrBinding.getSelectedValue();
    if(scopeId instanceof Row){
        predicates.add(new Predicate("jcr:content/idc:metadata/idc:xScope",Operator.EQUALS,((Row)scopeId).getAttribute("ScopeType")));

    Object createdDate=tempAttrBinding.getInputValue();
    if(createdDate!=null){
        predicates.add(new Predicate("jcr:content/jcr:created",Operator.EQUALS,createdDate.toString()));
    if (predicates.size()>0){
      return predicates;
return Collections.emptyList();
} The problem is while it's being called multiple times different list's are being returned which is causing the method not to work . The bean is in pageFlowScope .

That is bc ADF life cicle... Is always executing 2 times...

LoginModule login() method being called multiple times

I have a J2EE application that is deployed in Oracle 10g 10.1.2.0.2 that implements a cutom login module. The custom class (MyClassLoginModule) implements the LoginModule interface. Everything works great if the username and password entered by an end user are correct. However, it appears that if a user enters an incorrect password after failing authentication the container executes the MyClassLoginModule.login() method again. In some cases, it calls it serveral time each failing authentication.
This wouldn't be a problem however, the username and password are also the end users workstation accounts. This behaviour is capable of locking their accounts in one failed attempt.
Any help or insight would be greatly appreciated.

We're using FORM based authentication. The problem is not with multiple requests, but appears to be an issue with the container. See the following for more info:

ProcessAction for portlet being called twice

I am creating jsr-168 portlets on sun studio 8 . the problem that i am facing is that ProcessAction method seems to be called twice. Yet when i actually deploy the portlet on sun portal server 6 . They run well (i.e the method is called only once) . Can any body explain this? is this a bug or some configuration error at my development simulation server ? please help.
regards

This is a known bug indeed. If I'm not mistaken a fix for it was released as part of Update Pack 3 for JSE 8. Please check whether the update is available on the Update Center. Tools->Update Center

Unwanted behavior: Action method being called several times

Hello,
I have a managed bean that calls a session ejb which itself does a search. The problem is that it is supposed to retrieve a resultset ONCE and the displayed behavior is that it never stop doing so. It fetches the resultset N TIMES.
Here is the managed bean and the method to look at is the performSearch method:

Getting methods to call each other (",)????

Hi all i wonder if anyone can help me? I'm new to Java and am having a bit of difficulty in processing this program:
i am required to produce a template called rectangle.java, then i have to produce a second file called rectangle2.java which contains only a 'main' method, this is supposed to act as the test harness for my rectangle class - how do i acomplish this?
i understand that the two files must be in the same directory, but i am unsure of the structure each of the two files is to take, i think one of the files is providing the other file with raw data that is then manipulated through a method, but i am really not sure how to do this???
Please help (",) ?????
cheers

class Rectangle{
     static double RectangleArea(double a,double b){
          return a * b;
}class Rectangle2{
     public static void main (String args[]) {
          Rectangle r = new Rectangle();
          double area = r.RectangleArea(12,12);
          System.out.println(area);

Using rendered= stops action method being called on commandButton

Help help help please.
I have a managed-bean defined at "request" scope. This bean contains an encodedId field which is a string. This string is present in the form as a hidden field. On submit of the form, this setEncodedId is called on my bean, which then decodes the string and does setup of the bean.
The problem I have is that if I use a commandButton with rendered="#{MyBean.renderNextButton}" and the result of isRenderNextButton() is dependent on encodedId from the submit, then the button IS correctly rendered, but the action tied to the button fails to be called and the same page reloads when the button is clicked.
However, if I hardcode 'true' as the return value of isRenderNextButton() then the button renders and the action is called correctly.
I've also noticed that isRenderNextButton() is called four or more times on each submit even through I've only got one button using this rendered expression.
Any ideas anyone?

Without spending lots of time investigating, could I
write my own implementation of commandButton that
could have the render state encoded in the state
information I see encoded in the form?I can't understand the reason why you insist to hold the information in the component,
while the only you should do is to use a session scope bean to hold it using the standard JSF mechanism.

DoGet called twice on Tomcat Startup

Hi,
I have a problem with my Servlet doGet/doPost method being called twice (sometimes three times) on Tomcat 5 startup with J2SE 1.4 and Java SE 6. This problem happens on both, Firefox and Internet Explorer.
I only have one Servlet (called ServletFrontController) in my descriptor, since I decided to use the Front Controller Pattern. This Servlet extends from a "base Servlet" which has all the init configurations. My deployment descriptor looks like this (I also have mappings which I haven't included here):
    <servlet>
        <servlet-name>MainServlet</servlet-name>
        <servlet-class>com.myprogram.ServletFrontController</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>application.properties</param-value>
        </init-param>
    </servlet>My doGet / doPost / doHead methods from the base Servlet just delegate to the ServletFrontController "main" method, like this:
public final void doGet(HttpServletRequest request, HttpServletResponse response) {
        try {
            process(request, response);
        } catch (Exception e) {
            handleException(e, request, response);
}Does anyone had this problem and know why this could happen?
Martin
