NullPointerException on page load

I have attached my application code (Application1) and the war file. Please have a look.
lovtest.jsff is the page fragment that gets called by the main page (MainPage.jspx)
On page load I get this exception on page load:

What is your Jdev Version ?
I tried to open you file in Jdev 12.1.3 and it worked fine without any issues.
Can you try to delete the .data and classes folder and restart Jdeveloper and see what happens ?

How to initialize an adf component before a page loads

Hi all
I use JDeveloper 11.1.2.2.0
I have two pages:
first page has a link to a second page
<af:document title="first.jspx" id="d1">
<af:form id="f1">
    <af:commandLink text="Page 2" id="cl1" action="goToSecondPage" actionListener="#{Bean.handleLinkActionEvent}"/>
</af:form>
</af:document>and the second page has an inputText component:
<af:document title="second.jspx" id="d1">
<af:form id="f1">
    <af:inputText label="Text" id="it1" binding="#{Bean.inputText}" readOnly="true"/>
</af:form>
</af:document>First I load first.jspx and than I click the link. This event is handled in handleLinkActionEvent() method, in which I want to set a value to the inputText component of the second page. But I can't do it, because as expected I get NullPointerException.
So the question is how to initialize an adf component before a page loads?

Thanks a lot for your replies and links, it gives me some new knowledges.
I got your approach and achieved the aim for the described situation with tag <f:setPropertyActionListener>:
<af:commandLink text="Page 2" id="cl1" action="goToSecondPage"
                       actionListener="#{Bean.handleLinkActionEvent}" binding="#{Bean.firstPageLink}">
<f:setPropertyActionListener target="#{pageFlowScope.text}" value="Hello, World!"/>
</af:commandLink>and for the inputText component I set the value:
<af:inputText label="Text" id="it1" binding="#{Bean.inputText}"
                              readOnly="true" value="#{pageFlowScope.text}"/>I used request scoped managed bean and it is shared for both pages.
I understand that I can set a value of some attribute for managed bean
and use it to set a value for inputText component of the second page,
but as I understand it is almost the same way as usage of tag <f:setPropertyActionListener>.
In my real situation on the second page I have a dynamic table, and it's field is read only.
Structure of this table depends on a link clicked on the first page.
So I define components for table columns in runtime, it may be outputText, inputDate, goLink and some others.
And I have to get table through the UIComponent binding to set columns.
Certainly I can define all needed components for all columns
and render it according to the column types
<af:table value="#{Bean.collectionModel}" var="row" id="t1" binding="#{Bean.mainTable}">
   <af:forEach items="#{Bean.columnDescriptionList}" var="column">
      <af:column headerText="#{column.caption}" id="c1">
         <af:outputText value="#{row[column.fieldName]}" id="ot1" rendered="#{column.type == '1'}"/>
         <af:inputDate value="#{row[column.fieldName]}" id="ot2" rendered="#{column.type == '2'}"/>
         <af:selectBooleanCheckbox id="sbc1" selected="#{row[column.fieldName] == '1'}" rendered="#{column.type == 'n'}"/>
      </af:column>
   </af:forEach>
</af:table>but I think it is not very good.
Have you any idea?
P.S. I hope I clearly explained my situation =)

Puzzling error on programmatic page load

          I sincerely hope someone can help me here. I have no idea what's causing this
          particular error:
          <Oct 1, 2002 5:04:03 PM PDT> <Error> <HTTP> <101017> <[ServletContext(id=5808049,name=onstream,context-path=/onstream)]
          Root cause of ServletException java.lang.NullPointerException

          at weblogic.security.service.SecurityServiceManager.runAs(SecurityServiceManager.java:721)
          Since that error is all fairly internal to WebLogic's servlet service, I have
          no idea where to start looking for a solution.
          Here's what I'm doing. I have a JSP page with access to some session beans.
          I'm not using any servlets, just JSP. The initial page load (index.jsp) is successful
          and populated with dynamic data. I then have a form submit that occurs that posts
          to the same page (index.jsp) which checks for the form variables at the top of
          the page.
          The user logs in, loads index.jsp, clicks on a link that launches the form submit,
          and index.jsp should pop back up with new data populated based on the user's selection.
          Instead, I get the exception shown above on mouse click.
          Any insight would be appreciated! Am I not allowed to request the JSP page in
          this manner? Is it possible that the error is in my JSP code, or is it a security
          violation of some sort? A misconfiguration?
          Thanks!

          So the problem turned out to be the classic stupid java error whereby I was checking
          for string equality in an if statement using (String == String) rather than String.equals(String)
          method.
          Thank you, Kevin and Ann, for pointing me in the right direction.
          However, I am still not able to get the server to stop deleting the generated
          .java file. In order to grab __index.java I had to ctrl-c the command window
          immediately after the file had been generated. Kind of silly, but it worked.
          If anyone can tell me how to get it to save the files generated from Jsp2Java
          I'd greatly appreciate it.
          Thanks!

Hi,
Do you get this error when deploying to the Integrated WLS? Or a standalone instance? If it is standalone instance, does this work fine when you run with Integrated WLS?

Getting Page Load Error while opening a Opportunity in new window

Hi All,
outbound SSO is enabled.
when i try to punch-in to my application from CRM through opportunity web link with Web Link Target as "open in custom tab" its working properly, but when i have Web Link Target as "open in new window" i am getting page load error. previously with out Outbounf SSO it is working properly.
Do i need enable any settings in CRM
thanks

when the web link target is "open in new window" or "open in current window" the request send to third party application from CRM ONDemand is HTTPS request as SSL is not enabled it is giving "page load error"(In the web link we are specifying http only) (User athentication type is "username & password/ SSO")
Is there any setting in CRM Ondemand to send Http request only instead of HTTPS?

I want to writte C# code for 503 Service Unavailable error to web application page immediate close connection any page loaded

Here is a ticket regarding our current client web application ( Image data add, edit , delete in folder with form data in MSSQL Database) that using code c#, web form, ajax, VS2008, MSSQL Server2008 , it appears that there is an error where the HTTP
503 error occurs.
. Below is a conversation with Host Server support assistant.Can you take a look at it?
Ben (support) - Hi
Customer - We're having an issue with our windows host
Ben (support) - What's the issue?
Customer - 503 errors
Ben (support) - I am not getting any 503 errors on your site, is there a specific url to duplicate the error?
Customer - no, it comes and goes without any change Customer - could you have access to any logs ?
Ben (support) - Error logs are only available on Linux shared hosting, however with this error it may be related to you reaching your concurrent connections
Ben (support) - You can review more about this at the link \
Customer - probably yes - how can we troubleshoot ?
Ben (support) - http://support.godaddy.com/help/article/3206/how-many-visitors-can-view-my-site-at-once
Ben (support) - This is something you need to review your code and databases to make sure they are closing the connections in a timely manner
Customer - we're low traffic, this is an image DB to show our product details to our customers
Customer - ahhhh, so we could have straying sessions ?
Ben (support) - Correct Customer - any way you could check if it's the case ?
Customer - because it was working previously
Ben (support) - We already know that's the case as you stated the 503 errors don't happen all the time if it were issue on the server the the 503 would stay.
Customer - so our 2/3 max concurrent users can max out the 200 sessions
Customer - correct ?
Customer - is there a timeout ?
Ben (support) - no that's not a time out concurrent connections are a little different then sessions and or connections. Lets say for an example you have 5 images on your site and 5 7 users come to your site this is not 7 concurrent connections but 35. They
do close after awhile hence why the 503 error comes and goes. You can have these connections close sooner using code but this is something you have to research using your favorite search engine
Customer - thank you so much
Customer - I'm surprised that this just started a few weeks ago when we haven't changed anything for months
Customer - any changes from your side ? lowering of the value maybe ?
Customer - I'm trying to understand what I can report as a significant change
Ben (support) - We haven't touched that limit in years
Ben (support) - This could just be more users to your site than normal or even more images
Customer - I was thinking that could be it indeed
Customer - so I need to research how to quickly close connections when not needed
Ben (support) - Correctly
Ben (support) - correct
Customer - thanks !!
Ben (support) - Your welcome
Analysis :
The link provided tells us : All Plesk accounts are limited to 200 simultaneous visitors.
From what Ben (support) says and a little extra research, if those aren't visitors but connections then it's quite easy to max out, especially if the connections aren't closed when finished using. I'd suggest forwarding this to Kasem to see what he thinks.
Cheers,
Customer

After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.<br />
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time.<br />
There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.<br />
Another possibility is to use:
* [http://kb.mozillazine.org/Menu_differences Firefox (Tools) > Options] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

Skud,
you can create condition in report region query e.g. where 1 = :PXX_ITEM, and populate that item on click and then refresh report.

No data found in report csv or pdf output on first page load

No data found in report csv output on first page load. Report shows up on page, but no data found in csv or pdf output. I always need to submit the page and then it shows data in downloads. The page contains a form (read-only) with a report that references 4 page items by using something like the following:
and b.employee_no = v('P5_EMPLOYEE_NO')
and c.fisc_year_pk = v('P5_FISC_YEAR_PK')
and b.job_class = v('P5_JOB_CLASS')
and b.organization = v('P5_ORGANIZATION')
Again, report in the page shows up except there is no data in downloads. Can anyone help me solve this problem? I'm running Oracle APEX 4.2.1 in Oracle database 11gR2.
Thanks.

Sounds like a classic session state issue.
You need to populate you page items using page rendering computations to ensure they're set to session state.
Or if the download is triggered from a button press, you need to ensure those page items are submitted to session state, perhaps via a PL/SQL action.

ADF ProcessScope -- I get a new AdfFacesContext on each page load

I am trying to store some variables in the ADF processScope. But the next time the page is loaded and calls the managed bean methods, the AdfFacesContext is different, and so the processScope is empty. The managed bean is session scope, and I am setting the processScope variables in the bean's Java code.
In particular this happens when I click on the af:table pagination links, e.g. the "next 25".
How can I get access to the same AdfFacesContext (and therefore the same processScope) the next time the page loads and calls the managed bean?
I am using JDeveloper 10.1.3.3.0.
Here is the example code, and the output that is produced from my System.out.println statements:
========== Controller.java (session scope managed bean) ===============
package adfproject;
import java.util.Map;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import oracle.adf.view.faces.context.AdfFacesContext;
public class Controller {
private List<Map> list = new ArrayList<Map>();
private String label;
private static int counter;
public Controller() {
// initialize list with Map objects
for ( int i = 1; i<10 ; i++) {
Map map = new HashMap();
map.put("A","first column");
map.put("B", "row " + i);
list.add(map);
// called from JSP to initialize the ECO bean
public String getLoad() {
printAdfProcessContext("in getLoad");
// get value from current process scope
String currentLabel = (String)getProcessAttribute("LABEL");
// print currentLabel
System.out.println("current LABEL = "+currentLabel);
// if currentLabel null, build new one with counter, incr counter
if (currentLabel == null) {
label = "xyz " + ++counter;
System.out.println("new LABEL: "+label);
// remember the current label in the process scope, and in member
setProcessAttribute("LABEL",label);
return ""; // empty string so nothing is displayed on web page
public static void printAdfProcessContext(String label) {
AdfFacesContext afCtx = AdfFacesContext.getCurrentInstance();
System.out.println("============ "+label+" ===========");
System.out.println("AdfFacesContext = "+afCtx);
Map ps = afCtx.getProcessScope();
System.out.println("Process scope = "+ps);

08/09/03 15:32:42 new LABEL: xyz 2
====== Comments =========
As you can see above, the AdfFacesContextImpl object has changed, so I have lost the ProcessScopeMap.
Also, on the displayed page, the label is still "xyz 1" instead of changing to "xyz 2".
Thanks for your help,

Thanks for the idea, Murph.
I didn't need a session scope bean, request would be fine, I just was trying to make something work that would allow me access to the process scope attributes. I want to allow multiple browser windows searching on different objects independently, so I don't want to use session scope.
I tried removing the variable declaration and setting/getting the processScope attribute in the setter/getter methods, to make the process scope attributes independent of the managed bean. But each time the page loads (by clicking the table navigation links), I still lose the process scope attributes. I tried with both session and request scope beans. Either way, in the getLoad() method, when I try to get the label from the process scope (using the new version of getLabel()), it is null.
So the root problem is still there.
For continued discussion on this more specific problem, see my separate thread "JSF ProcessScope attribute missing on page reload from af:table pagination"
at JSF ProcessScope attribute missing on page reload from af:table pagination

Firefox crashes as soon as the page loads it is completely unusable

i got a update prompt from firefox a few hours ago which i installed and now it wont work as soon as the page loads it crashes it wont even stay on long enough to figure out the problem i swear by firefox i have used its for years and never had any problems with it ever if i recall but lately it has been freezing and crashing often i feel like i am using internet explorer and thats bad but now i cant get it to work at all and am forced to downgrade to a lesser program WHAT IS GOING ON????? as for crash ids and troubleshooting info none of that even comes up

Do a clean (re)install:
* Download a fresh Firefox copy and save the file to the desktop.
* http://www.mozilla.com/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Firefox has been randomly crashing for two days. I always have google and facebook running. Firefox seems to crash at random times - no specific web page loading. My Firefox is up to date.

There can be multiple reasons for crashing. Seeing this article would be helpful as it lists out the solution for this-

I have just downloaded the latest version and some sites are part loading then taking ages to complete the page load. why and can you or I do anything about it please.

latest version loads the main banner of page then takes too much time loading the content of page > I have even had to stop the page loading and refresh before it will load properly> I did not experience this before installing the latest version the pages used to load insantaneously. I am not the only one experiencing this as my friend has reverted back to explorer.
Please can you do something about this.

It could be caused by a Firewall. Disable your internet security and then see if QT will open.
Are you an administrator account? It could be a permissions issue. Open the User Accounts control panel to see what type of account you have. Open the QT control panel to File Types. Does it show programmatically set? If so that will indicate permissions have been set by an administator.
Also are there too many applications running at once or loading at start up? Look down at the bottom right corner of the screen, is it loaded with icons? If so close them all out and stop them from running at start up, then see if QT will open. The only application that should load at start up is your internet security and maybe volume control, anything else you can open as needed.
If none of the above is a solution than I can help you uninstall QT and install, if so what version of QT is on the computer now. Open the QT control panel and click on About QuickTime

Spry Accordion - Tabs open and then close after page loads

I am using a Spry Accordion menu driven from a database.
The menu opens up during the page load and then closes.
I'm using SpryAccordion.js 1.6.1
And to open a preset tab, I'm using:
<script type="text/javascript">

</script>
But, all of the tabs open and then close on page load.
My page:   http://www.texashotjobs.us/00C01.aspx
Any fix for this??
Thanks, Ron

Well to both thanks. Actually I wasn't disappointed as I had a two part question...
I tested the 1.6 JS and remembered that I had to modify the 1.4 so that tabs actually would link. So I reverted back to 1.4.
So, going to 1.6 fixed the open panel on load but "unfixed" the panel tab from linking.....
So changing this in the 1.6 js fixed the link issue as well:
Spry.Widget.Accordion.prototype.onPanelTabClick = function(e, panel)
    if (panel != this.currentPanel)
        this.openPanel(panel);
    else
        this.closePanel();
    if (this.enableKeyboardNavigation)
        this.focus();
//    if (e.preventDefault) e.preventDefault();
//    else e.returnValue = false;
//    if (e.stopPropagation) e.stopPropagation();
//    else e.cancelBubble = true;
I t appears everything is working........
Thanks, Ron Gaddis
