Re: Blank page after form validation

[Matt Raible]

Most likely your "input" attribute is invalid - this usually results in 
a blank page in my experience.

Can anyone let me know why this is happening? It is not going to the

Re: Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up

[Kam Lung Leung]

Hi Ted,

Thank you for your time in helping me out. After your email message I 
take a hard look at the jsp file and can not find what was wrong with it.
The secondPage.jsp is almost the same as the firstPage.jsp. When
I move all the code from the secondPage.jsp to the firstPage.jsp the 
validation process went fine. All fields are validated by the validator.
I have given up the hope to create a multipage form for now. And by the way 
I have purchased the Struts In Actions book along with other three books 
on the same subject. But there was not must information on multipage form. 
Do you have any suggestion on book that I may find some complete example 
on multi page form. To answers your your question about why do I reset all 
input fields to its original state when the getPage() is equal to 2 is that 
I only have two pages,firstPage.jsp and secondPage.jsp, each page would set the
page number to "0" and "1" correspondingly. I set the page to 2 in the action
class when the secondPage.jsp was executed. Then I call the form's reset method
to clear all the fields before the control goes back to the firstPage.jsp. I
guest you are right about removing the form bean should be good enough to remove
all attributes in form for both pages.

Thank again.

Are you sure that it's blank? Sometimes the page doesn't render because 
of errors in the HTML, which might only be exposed when the page is 
trying to display error messages.

I'm not sure why you would reset everything if getPage() is equal to 2. 
The usual approach is to allow the properties to accumulate, until the 
end of the workflow, and then dispose of the (session-scoped ActionForm 
altogether. Generally, the only thing you ever need to reset is a 
checkbox to false on a session-scope ActionForm.

Hi,

I have been looking at this problem for the last four days and can't figure
out. I have an application that required workflow form. I created a
CreateUserAccountAction class that extends the DispatchAction and a form
MultiCreateUserAccountForm that extends the ValidatorForm.  The reset method of
the MultiCreateUserAccountForm clears all attributes under the current session
when the getPage() is equal to 2. The CreateUserAccountAction has two methods
that are similar to the execute method that are named createUserAccountActionOne
and createUserAccountActionTwo. I got this concept out of chapter 12 of the book
Profession Jakarta Struts by James Goodwill and Richard Hightower.
*** Here are the symptoms  **
If there is a required field that is missing (leaved out) or does not fulfill
the validation rule on the firstPage.jsp when the submit button is pressed. A new
dialog box popped up on the screen with the validation message(s) from the

the secondPage.jsp.
If there is a required field that is missing (leaved out) or does not fulfill
the validation rule on the secondPage.jsp when the submit button is pressed. A

page are filled in correctly according to the validation rules then the control
is correctly forwarded back to the firstPage.jsp.

*** ***More detail on how the jsp was set up  **
The createUserAccountActionOne method calls the

RE: No Error Message But A Blank Page Is Displayed.

[Caroline Jen]

I am very grateful for the overwhelming help that I
have received.  

I followed the advices given by all of you and paid
special attention to possible mis-spelling in forward
mapping.  I did not find any mis-spelling or mixing up
of lower case/upper case.

Finally, I re-typed all the key words in the forward
mapping parts of the program.  Everything worked -  I
got the expected page displayed in the browser.

I still do not have any idea why I got a blank page
last night.  I would be more than happy to share my
experience with all of you if I knew the root cause of
the problem.  But, I do not know.

RE: No Error Message But A Blank Page Is Displayed.

[Richard J. Duncan]

In my experience, this is because your execute/perform is returning null as the result 
of findForward("forwardname") not finding anything. Usually, this is because I 
misspelled the forward name.

Returning null from execute/perform tells struts that your method wrote the response 
itself.

RE: No Error Message But A Blank Page Is Displayed.

[Srinivas Gunturu]

I have seen this behavior when the jsp page I am forwarding to is not found such as in 
wrong location, wrong case (Welcome.jsp vs welcome.jsp).  But we are using tiles so 
not sure if it is tiles specific or not.

Hope this helps.

Re: No Error Message But A Blank Page Is Displayed.

[Caroline Jen]

My welcome page "is displayed" as the very first
screen without any problem.  The page has
 and  tags, which
test if any registered user has logged on.  

The problem occurred after I filled out username, and
clicked the "Submit" button.  Thereafter, the welcome
page was not shown.  My welcome page looks like the
following:

Welcome.jsp

<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Welcome!




Welcome !


Welcome World!

RE: No Error Message But A Blank Page Is Displayed.

[Chen, Gin]

I'm not sure where in your scenario the error was supposed to occur.
I would suggest just right clicking on the blank page and see what the src
holds.
If you change the last line to:

ActionForward valForward = mapping.findForward(Constants.VALID);
servlet.log("Forwarding to: " + valForward );
return valForward;

That might help too.

Subject: No Error Message But A Blank Page Is Displayed.


I am experimenting a basic application - logon.  I got
the first two screens working without problem. 
However, the third screen displays a blank page (no
error message).  I am having a very difficult time to
figure out the problem; henceforth, seeking help. 
Here is the history of my application:

1. http://localhost:8080/LogonPractice/index.jsp (no
problem and I clicked on "Sign in")
2.
http://localhost:8080/LogonPractice/Logon.do;jsessionid=170B50E4D8E07EE36290
E98342E8BF9C
(no problem and the screen asked for username and
password.  I filled out the information and clicked on
"Submit")  
3. http://localhost:8080/LogonPractice/LogonSubmit.do
(displayed a blank page)

The Tomcat log file shows the following (no error
message at all):

Re: No Error Message But A Blank Page Is Displayed.

[Kwok Peng Tuck]

You might want to put System.out.println("Line [number]") ; to see
the flow in your action. BTW did you actually put anything(like hello 
world) in Welcome.jsp ?

Re: validator returns blank page

[Koni Roth]

Hi Thomas
Here what I would do.
struts-config.xml:

   

   
LogonAction.java:

  ActionErrors errors = new ActionErrors();
  errors = form.validate(mapping, request);
  // Report any errors we have discovered back to the original form
  if (!errors.isEmpty())
  {
  saveErrors(request, errors);
  return  new ActionForward(mapping.getInput());
  }
And be sure that your Class extends DynaValidatorForm.
Hope this helps
Koni

I'm attempting to use the validator with a DynaValidatorForm and it

And if I fill the username field I'm redirected to the good page
(/index.jsp).

any idea?

RE: Repost: Clicking "Submit" returns a blank page

[Bailey, Shane C.]

BTW, to debug have you tried to do mapping.findForward("success") and
mapping.findForward("fail") to see what happends?

A couple of observations:


1. Not that it is the solution but could you do  ?  Only because Logon.do is a forward (action
anyway).

2. Again, probably not necessary but add method="post" to the form tag.

3. I doubt it is a problem but I am so used to seeing the action attributes
on the same line you could move all the attributes like name="logonForm"
onto their own line.  You just never know when things should work and
aren't.

You already verified that LogonSuccess.jsp exists and isn't blank.  

I agree though with the post about verifying that the constant is the right
value. I have seen the blank page problem when I changed the name of my
forward in the struts config and didn't rename it in my action.

There is no null pointer exceptions or other exceptions being thrown in your
container output window?

I have exhausted everything I could think of for now.

Subject: Repost: Clicking "Submit" returns a blank page

I have reached this far in my debut logon page
development...
 
The first JSP page comes up fine, showing me a form
 with a rendered
 tag for each required field (username
and password), plus a "Reset" and a "Submit" button.
Code sample below comes from my struts-config.xml
file:
 

 

 

 



 
 


 

 
** struts-config.xml code above
**

I can enter data into the  fields and
they will erase if I click "Reset"
I can click "Submit" with nothing filled in (passing
nulls with the request), and the proper
 are displayed.

However...

If I enter any values for the "username" and
"password" fields, then click "Submit," a blank page
is always returned (neither "LogonSuccess.jsp" nor "LogonFail.jsp" are
blank).

What's up with that?  The browser says it's trying
to display results from "LogonSubmit.do" (which is
what I expect).  I have a file called
"users.properties" in the directory
"WEB-INF/classes" and in my LogonAction.java code:

public final class LogonAction extends Action {
 
   public ActionForward execute( ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response )
  throws Exception {
  
  String username = ( ( LogonForm ) form ).getUsername();

  }
  }

Note: The LogonAction.java file above makes use of the following

Repost: Clicking "Submit" returns a blank page

[todd thorner]

I have reached this far in my debut logon page
development...
 
The first JSP page comes up fine, showing me a form
 with a rendered
 tag for each required field (username
and password), plus a "Reset" and a "Submit" button.
Code sample below comes from my struts-config.xml
file:
 

 

 

 



 
 


 

 
** struts-config.xml code above
**

I can enter data into the  fields and
they will erase if I click "Reset"
I can click "Submit" with nothing filled in (passing
nulls with the request), and the proper
 are displayed.

However...

If I enter any values for the "username" and
"password" fields, then click "Submit," a blank page
is always returned (neither "LogonSuccess.jsp" nor "LogonFail.jsp" are blank).

What's up with that?  The browser says it's trying
to display results from "LogonSubmit.do" (which is
what I expect).  I have a file called
"users.properties" in the directory
"WEB-INF/classes" and in my LogonAction.java code:

public final class LogonAction extends Action {
 
   public ActionForward execute( ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response )
  throws Exception {
  
  String username = ( ( LogonForm ) form ).getUsername();
  String password = ( ( LogonForm ) form ).getPassword();
  boolean validated = false;

  try {
  
  validated = isUserLoggedOn( username, password );
  }
  catch ( SimpleUserDirectoryException sudexc ) {
  ActionErrors errors = new ActionErrors();
  errors.add( ActionErrors.GLOBAL_ERROR,
 new ActionError( "error.logon.connect" ) );
  saveErrors( request, errors );
  return ( new ActionForward( mapping.getInput() ) );
  }
  
  if ( !validated ) {
  
  ActionErrors errors = new ActionErrors();
  errors.add( ActionErrors.GLOBAL_ERROR,
 new ActionError( "error.logon.invalid" ) );
  saveErrors( request, errors );
  return ( new ActionForward( mapping.getInput() ) );
  }
  
  HttpSession session = request.getSession();
  session.setAttribute( Constants.USER_KEY, form );

  return ( mapping.findForward( Constants.SUCCESS ) );
  }
  
  public boolean isUserLoggedOn( String username,
  String password ) throws SimpleUserDirectoryException {
  
  return ( SimpleUserDirectory.getInstance().passwordIsValid(
username, password ) );
  }
  }

Logon "Submit" returns a blank page

[todd thorner]

Hi and thanks,

Ok, I have reached this far in my logon page development...

The first JSP page comes up fine, showing me a form  
with a rendered  tag for each required field (username and password), plus 
a "Reset" and a "Submit" button.  Code sample below comes from my struts-config.xml 
file:


 



 



 
 
   
   
  


** struts-config.xml code above **

I can enter data into the  fields and they will erase if I click "Reset"
I can click "Submit" with nothing filled in (passing nulls with the request), and the 
proper  are displayed
However,

If I enter any values for the "username" and "password" fields, then click "Submit," a 
blank page is always returned.

What's up with that?  The browser says it's trying to display results from 
"LogonSubmit.do" (which is what I expect).  I have a file called "users.properties" in 
the directory "WEB-INF/classes" and in my LogonAction.java code:

public final class LogonAction extends Action {

public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response )
throws Exception {

String username = ( ( LogonForm ) form ).getUsername();
String password = ( ( LogonForm ) form ).getPassword();
boolean validated = false;

try {

validated = isUserLoggedOn( username, password );
}
catch ( SimpleUserDirectoryException sudexc ) {
ActionErrors errors = new ActionErrors();
errors.add( ActionErrors.GLOBAL_ERROR,
new ActionError( "error.logon.connect" ) );
saveErrors( request, errors );
return ( new ActionForward( mapping.getInput() ) );
}

if ( !validated ) {

ActionErrors errors = new ActionErrors();
errors.add( ActionErrors.GLOBAL_ERROR,
new ActionError( "error.logon.invalid" ) );
saveErrors( request, errors );
return ( new ActionForward( mapping.getInput() ) );
}

HttpSession session = request.getSession();
session.setAttribute( Constants.USER_KEY, form );

return ( mapping.findForward( Constants.SUCCESS ) );
}

public boolean isUserLoggedOn( String username,
String password ) throws SimpleUserDirectoryException {

return ( SimpleUserDirectory.getInstance().passwordIsValid( username, password 
) );
}
}

** mystrutsactions.LogonAction.java code above **

Note: The LogonAction.java file above makes use of the following 
SimpleUserDirectory.java code:

private static final String SimpleUserDirectoryFilepath = "users.properties";
InputStream ips = this.getClass().getClassLoader().getResourceAsStream( 
SimpleUserDirectoryFilepath );

** mystrutsforms.LogonForm.java code above **

Also, my web.xml file has:


 application
 application


** web.xml code above **

Any suggestions or guesses are appreciated.

Re: My LogonView.jsp Displays A Blank Page

[Jason Lea]

I can't see anything wrong, I'll ask some questions :)

How are you accessing the logonView.jsp?  Requesting it directly or 
through an Struts Action?

Where is the MessageResources.properties file?  I see you use 
resources.version1.MessageResources which 
means it should be somewhere like 
/WEB-INF/classes/resources/version1/MessageResources.properties

If you went through an action, does the action actually forward to 
logonView.jsp?  What is in your struts-config.xml?

Perhaps your log files will show what Struts did with the request?

Hi everyone,
 
I have a problem with returning to the previous page using
findForward(). In my Action class, depending on the action which has to
be performed, I am forwarding it to a certain jsp. The code looks like
this
 
else if(strAction.equals("cancel")) {
 ((ChangeWelForm) form).setTheMessage(strMsgPrev);
return mapping.findForward("displayMain");
 
I have set ("displayMain") in my struts-config file :
 


 
 
But i get a blank page on performing this action!!
Can anyone please let me know if i'm missing something here since i'm
new to struts!!

RE: Using Frameset within Struts - displayed a blank page

[Tuan H. Le]

Hi Brian,

Thanks for your response! I tried to define a forward within the /selectTab action, 
but I still see a blank page. The new action mapping is below





Read the Struts archive, it seems that using tiles/template is a better choice than 
calling in action in the frame src attribute.

Also, it would be much appreciated if some one can share a sample code and 
configuration on how to develop tabs functionality with frame and tiles. I'm going 
through tiles-documentation tutorial. 

The layout that we have for our application is below

Top frame: Tab labels
Middle frame: content body
Bottom frame: other data and footer.

Thanks!
Tuan

Interesting.  Never tried calling in action in a SRC attribute.  Seems like it works 
since you are getting a blank page, and not a HTTP: 404 error ( Page not found ).

When I see blank white pages it is usually a problem with your forwards.  I don't see 
a forward defined in the selectTab action definition in the Struts-config file.
Is it a Global forward? is it misspelled in your code?  

Keeping in mind that the input attribute doesn't get checked for forwards, that is 
used for validation.

Using Frameset within Struts - displayed a blank page

[Tuan H. Le]

I have searched through the struts archive, but couldn't find a solution to my problem 
below. 

if I specified , it found and displayed the Top.jsp fine.

However, after I changed to , then it displayed a blank 
page in the top frame.

Do you know what I'm missing?

Thanks in advance

Did you remember to remove the form part of the action mapping? ie

Re: I try again... My action is not being called -I just get a blank page!

[Vilya Harvey]

Sorry, that was my mistake earlier: your HTML was correct. I thought you
were using the page="" attribute, rather than forward="", on the HTML link.

I don't know what else could be causing the problem; I can't see anything
obviously wrong. Good luck sorting it out though!

If I write /do/acceptanstest/accDatabase I get the same result -a blank 
page. And if I remove the form tag, I will get a servlet error: Cannot find 
bean databaseForm in scope null. I don't get it..

Both the action specified in your form, and the href for the link inside the
form are invalid. If you have mapped /do/* to the ActionServlet, then the
href should be /do/acceptanstest/accDatabase. Give that a try and see if it
helps.

As a side note, the  tag is not necessary here.

Good luck!

Réf. : I try again... My action is not beingcalled -I just get a blank page!

[Alexandre Albert]

I don't know what is wrong with your webapp, but I'm using Struts with 
WebSphere developer studio as well and it works fine. Try it with a simple 
blank webapp.
The only thing that is a bit unusual is the servlet-mapping, and also I 
nerver specify the type in the action-mappings.

No, look at my execute method:

 System.out.println("AccDatabaseAction :: execute");
 return (mapping.findForward("success"));
 }

Nothing is written in the console and an exeption is not being thrown. 
Nothin happens in the console! Nothing is printed, no error message. The 
action is not being valled, just a blank page shows up.

My struts-config.xml:

Re: I try again... My action is not being called -I just get a blank page!

[Bryan Hilterbrand]

Are you using Tomcat?  Check the Tomcat log -- some exceptions
get sent to the Tomcat log instead of the browser or console log
window.  The path will be something like:

C:\tomcat\logs\localhost_log.2002-09-24.txt

You will have to scroll to the bottom of the file to see the latest
entries.

I try again... My action is not being called -I just get a blank page!

[Ulrika Nordström]

No, look at my execute method:
public ActionForward execute(   ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response) {
System.out.println("AccDatabaseAction :: execute");
return (mapping.findForward("success"));
}

Nothing is written in the console and an exeption is not being thrown. 
Nothin happens in the console! Nothing is printed, no error message. The 
action is not being valled, just a blank page shows up.

My struts-config.xml:











 




  









***
AccDatabaseAction.java:

public class AccDatabaseAction extends Action {
public ActionForward execute(   ActionMapping mapping,

ActionForm
form,

HttpServletRequest request,

HttpServletResponse response) {
System.out.println("AccDatabaseAction :: execute");
return (mapping.findForward("success"));
}
}
***
DatabaseForm.java:
public final class DatabaseForm extends org.apache.struts.action.ActionForm

public String iName;

... or your collection/array you are using in a logic:iterate is null.
Struts 1.02 gets confused and sends back part of the header and
nothing else.

My action is not being called -I just get a blank page!

[Ulrika Nordström]

Hi!

I am trying to access an action but it is not being called. Nothing is 
happening in the console. In the execute()-metgod I write "AccDatabaseAction 
:: execute" but nothing is being printed. The only thing that is happening 
is that I get a blank page. The URL of the first index page looks like: 
http://localhost:8080/servlet/index.jsp and when I click the name the blank 
page will show up at 
http://localhost:8080/servlet/do/acceptanstest/accDatabase I can't see what 
I have missed and I have tried everything! I using IBM WebSphere Studio 
Application Developer and I have just downloaded the latest version of 
Struts 1.1b.

Please, I really need help with this.
Thanks, Ulrika

Next time you're not sure if the Action got hit, it's easy to test it by
putting a System.out.println in the class.  Watch for the message in the
server console.  It's a good thing to try before posting a question, because
you'll be more sure of what's going wrong.

findForward() returning a blank page

[Michael Gluckman]

Hi all

After my action class is instantiated the method findForward("admin")
returns a blank html page instead of the admin-frame page.
If I type the full URL path to the admin-frame it works.
I have included the  in the admin-frame page.
Any ideas

Thanks
Michael
