Blank page after form validation

[VENKATESH GANGAL]

Hi All,

We have been facing a very strange problem with form validation

We have a JSP which is an input to an action and there is an associated form bean to 
validate the form.

Here is the configuaration file
struts-config.xml:


  





  





 

  

validation.xml :




   
   
   
 




MessageResources.properties
form.error.productRef = Please enter Product Reference

FormBean Validation method :

 public ActionErrors validate(ActionMapping mapping,HttpServletRequest request) 
   {
   //ActionErrors errors = super.validate(mapping, request);
   ActionErrors errors = new ActionErrors();
if ((productRef == null) || (productRef.trim().length()< 1)){
errors.add ("productRef",new 
ActionError("form.error.productRef"));
}

   return errors ;
   }


Here is the JSP





 


  
   
  
 

   
   
 



When I submit this form without entering anything in the textfield, it is taking me to 
a blank page.

Can anyone let me know why this is happening? It is not going to the action at all and 
is returning with errors to the JSP.I am not able to reach the page from where I 
submitted the data along with errors.The error was added to ActionErrors object.

We are using oc4j(Oracle Apps) standalone application.We are using struts 1.1

Thanks in advance for your help.

Cheers...
Venkatesh

activeCount, useCount increasing automatically

[shankarr]

Hi!
What is worrying me is that the number of activeCount and useCount are 
increasing though there have been no db interactions.
Any help, appreciated.

This is my data source entry from struts-config.xml file. Is there 
something wrong in it ?

  






















  

This is how I get my dbconnection in my action files

  Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
ServletContext context = servlet.getServletContext();
DataSource dataSource = (DataSource) 
context.getAttribute(Action.DATA_SOURCE_KEY);
String target = "success";
conn = dataSource.getConnection();
stmt = conn.createStatement();

I am getting the following in my tomcat prints.

INFO:Found available connection
Jan 14, 2004 10:04:32 AM org.apache.struts.legacy.GenericDataSource 
getConnectio

Re: Database pool full.

[Max Cooper]

My guess is that you have a connection leak somewhere. Does this problem
start occurring immediately, or does it only show up after visiting a number
of pages in the site?

Various db pools have different ways of dealing with no connections being
available. Often, you can configure which strategy to use. Here are 3
different strategies:

1. Wait until a connection becomes available.
2. Fail if no connections are available (i.e. return null or throw an
exception).
3. Grow the pool temporarily if there are no free connections.

It is clear from the errors you are getting that your pool is currently
using strategy #2. I like #1 the best, because it is less likely that
requests will fail under load. But, you must be sure that you don't have any
connection leaks, because the app will eventually hang if you have
connection leaks and use strategy #1. Strategy #3 works, but you can run
still run out of connections in the database itself, so it can start to act
like strategy #2. This is one aspect of connection pooling that important to
consider when developing web apps.

But, it seems likely that you have leaks somewhere. Some of your requests
are probably not returning their connections to the pool. It could be that
you have exceptions that are being thrown and not releasing the connection,
or it could just be that you have non-exception logic paths that don't
return the connections. Some combination of code reviews, debugging, etc. is
needed to track them down.

Another thing to watch out for is requests that require more than 1
simultaneous connection. For instance, consider the situation where you have
a pool of 30 connections, 15 request handler threads, and a request that
requires 3 connections. If 15 of those requests come in at once, and each
request handler thread grabs 2 connections, you will have deadlock as all
the request handler threads wait forever for a third db connection to become
available (assuming you are using pooling strategy #1 above). The solution
to this problem is to make sure that you don't have any requests that
require more than one simultaneous connection, or at least that your db
connection pool has enough connections to survive a flood of connection
hungry requests (e.g. have a pool of 45 connections in the example scenario
described above -- 3 conn/req * 15 threads = 45 connections in the pool).
This may seem unlikely, but it is a problem I have faced in a production
system (and it wasn't easy to track down!). Another lister here suggested a
good technique for ensuring that none of your requests require more than 1
simultaneous connection -- test your app with a pool of 1 connections.

Dear All,

I am developing an application on resin-2.1.9 web server.
Connection to MYSQL Database is using JNDI. JNDI connection code is written
in a class called DBService.
I am instantiating DBService class where ever i need database connection and
getting connection using getConnection() method.

when user start working on  application, i m getting following errors,

Class:DBService. Method:getConnection() cann't open connection with full
database pool(30)
Class:MonthReport. Method:SelectReportDetailNull() cann't open connection
with full database pool(30)

it sounds like database pool is full, Whether i need to increase the pool
size or optimize code in DBService database connection class.

for your reference below code  performs database connection.

--
public Connection getConnection()
{
java.sql.Connection con = null;
javax.sql.DataSource ds=null;

try{

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
ds= (DataSource)envCtx.lookup("jdbc/training");
con = ds.getConnection();

}catch(Exception e){
System.out.println("Class : DBService, Method :
getConnection()"+e.getMessage());
}
return con;

}//end of getConnection method

Re: handling form based authentication w/ remember-me cookie

[Matt Raible]

They should be getting called for both - since they both are a 
"request".  You might try adding the  element to trap 
forwards as well.  This is a Servlet 2.4 feature.


loginFilter
/security/*

REQUEST

Dipak,

Are you certain that the filter will be invoked on the 
/j_security_check
request when container-based security is used? I have not tested 
this, but
it would not surprise me to find that some containers do not execute 
filters
on /j_security_check requests. I don't know if the Servlet Spec says
anything about this case.

Chris,

Another alternative to the original problem of security with 
"remember me"
functionality will be available soon. A patch has been submitted to my
SecurityFilter project (http://www.securityfilter.org/) to support 
"remember
me" functionality. The integration should be complete soon, and a beta
release will be made available once the integration is complete.
SecurityFilter works very much like container-managed security 
otherwise,
including the configuration format (except that you declare the 
constraints
in a separate config file rather than web.xml).

Hi Chris,

You can do this using Servlet Filter.  What you need to do is write
postLoginFilter that maps to the j_security_check url.
In doFilter method, you can write your post login code after
j_security_check done is work.
Something like:
public void doFilter(.)
// let the j_security_check to do it's work
chain.doFilter(request, response)
// do you post login stuff here

Database pool full.

[virupaksha]

Dear All,

I am developing an application on resin-2.1.9 web server.
Connection to MYSQL Database is using JNDI. JNDI connection code is written in a class 
called DBService.
I am instantiating DBService class where ever i need database connection and getting 
connection using getConnection() method.

when user start working on  application, i m getting following errors,

Class:DBService. Method:getConnection() cann't open connection with full database 
pool(30)
Class:MonthReport. Method:SelectReportDetailNull() cann't open connection with full 
database pool(30)

it sounds like database pool is full, Whether i need to increase the pool size or 
optimize code in DBService database connection class.

for your reference below code  performs database connection.

--
public Connection getConnection()
{
java.sql.Connection con = null;
javax.sql.DataSource ds=null;

try{

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
ds= (DataSource)envCtx.lookup("jdbc/training");
con = ds.getConnection();

}catch(Exception e){
System.out.println("Class : DBService, Method : 
getConnection()"+e.getMessage());
}
return con;

}//end of getConnection method
-

Your advice will be great help to optimize my application.

Thanks in advance.

Re: converting with variable target into

[hgosper]

I like to avoid putting javascript logic in the JSP tag itself (although 
you can usually do it if you get the syntax right).

I usually pull the script out of the tag like this:


function deleteEvent()
{
if (confirm('Do you want to delete this event?'))
{
location = '/EventDelete.do?e=' + 
document.all("eventId").value;
}

}









I know that's a bit different to what you are doing but that is how I 
would do it and your javascript is nice and clear (you can even put it in 
a separate file).

So is there a way to do this in ?

And is there a need to convert all  to  in the first place?
Because I am also having problem converting

<%=
htmlescape(evcontactemail) %>

into , since there is no paramId that I can specify, and using
paramId always automatically add a ? to the created link.


Thanks in advance on any pointers,

Re: handling form based authentication w/ remember-me cookie

[Chris Ruegger]

Craig,
Ok fair enough. If the spec says it is undefined, that what is one to do?
Keep in mind I'm trying to do the right thing here and build an application
where people can logon AND I can send them a cookie to remember their user
ID.
What is the propery way to do this under J2EE/Struts? Apparently I'm not
allowed
to intercept calls to j_security_check so I should be doing something else?
That's fine,
lots of web sites do this, how should I be doing it?
Thanks,
Chris

Struts 1.1 on iPlanet 6.05 iws (one more time)

[Fowler, David]

I'm a little closer.

I am running Struts 1.1 on iPlanet iws 6.05 (it works fine on tomcat 3.3.1).  I am 
using JDK 1.4.1_05 (JDK 1.4.1_01 is the highest supported on 6.05).  The app is 
running on Windows 2000 - destined for HPUX.  I am also using tiles and validation.

At first, nothing worked.  I changed the action forwards to redirect=true.  I also 
moved the ApplicationResources.properties to the application context root directory 
(instead of WEB-INF/classes).  Now everything seems to work with one exception.  Any 
page using a dto throws a servlet exception.  If I take the dto out, everything works 
(of course the dto is the heart of the matter).

I've increased the maxHeapSize to 67108864 and the StackSize to 1024000 (I'm way out 
of my league here).  I have not set a size for my page output buffer.

Are there any suggestions about what paths I might investigate or what damage I have 
done???

Re: handling form based authentication w/ remember-me cookie

[Nadeem Bitar]

It is a huge disappointment that the servlet 2.4 specification didn't
address programmatic authentication. Dispatching requests to
j_security_check is a pain in many use cases.

I really hope that a future version of tomcat would address this even if
this didn't make it into the spec this time.

This is really a question for your servlet container provider, since it's not
Struts specific.  It's up to the server configuration whether "serverName" and
"serverName.mycompany.com" are considered to be the same virtual host or not
(which would be a prerequisite to sharing the session).  A couple of approaches
to consider:

* If your webserver considers the two to be different,
  put a redirect on one so that you always end up on the other.

* Construct all your hyperlinks without the "http://host"; part,
  and just start with a slash followed by the context path.
  That way, the browser will reconstruct an absolute URL
  using the server name (qualified or not) that came in on
  the original request.

For filters mapped to ordinary application URLs, the filter should indeed get
mapped on both GET and POST methods.  For filters you attempt to put on
"/j_security_check" you are totally outside the bounds of the servlet
specification, and the only thing you can assume is that the behavior is
undefined.

Personally, I consider it a bug that Tomcat 5 invokes filters on this, even if
it's just on a GET.

Re: redirecting to fully qualified hostname

[Brice Ruth]

What you're likely running into is the fact that the cookie that the 
application server uses to track a user's session object, is very 
specific to what host can read the cookie.

I use Apache and one of the things I've done is set a configuration 
parameter "UseCanonicalName" to be "on" - it defaults to "off" ... 
here's the comment in Apache's configuration that describes this parameter:

#
# UseCanonicalName: Determines how Apache constructs self-referencing
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client.  When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName On
Basically, if you define your "host" instance in Tomcat to be 
host.domain.com, then regardless if someone accesses http://host/ or 
http://host.domain.com/, Apache will populate the SERVER_NAME variable 
with "host.domain.com" - what this does, is when Tomcat then figures out 
what server name to specify for the cookie, it will use 
"host.domain.com", not whatever the user tried to access the application 
through.

Help? Yes? No? Hope so!!

Fullam, Jonathan wrote:

All,

The application I am working on is secured with a login that required a
username and password.  Once a user is logged in, all pages can be accessed
as long as there is a Subject object in the Session.  My problem is that
part of the webapp provided links to pages that open in another window, and
when the link is clicked, it is forwarding to the logon page as if the
Subject object is no longer in the Session.  I've determined that this
behavior is only present when the hostname used for the request is not fully
qualified upon the intial logon.
For instance.

User logons on by going to http://serverName/webapp/logon.do

Then the application provides a link to
http://serverName.mycompany.com/webapp/something.do which open a page in a
new window.
When the user click the link, a new window is opened but they are forwarded
to the logon page as if they never logged on in the first place.
How can I have all requests to the original hostname
http://serverName/webapp be redirected to
http://serverName.mycompany.com/webapp ?  Is there anybody out there that
has experienced this or knows of a better way to work around this issue?
Thanks in Advance,

Conclusion:

Your execute method is getting called... it is the one throwing the
exception. (Or the exception gets thrown when it executes a helper object).

See... com.faid.qa.actions.viewDataAction.execute(viewDataAction.java:19)

Send the above line of code with surrounding code.


Thought process

Check the signature of you execute method. Perhaps the default execute
method is getting called.

Hmm.

I looked line 484 of the RequestProcessor (from the stack trace that you
sent).

protected ActionForward
processActionPerform(HttpServletRequest request,
 HttpServletResponse response,
 Action action,
 ActionForm form,
 ActionMapping mapping)
throws IOException, ServletException {

try {
return (action.execute(mapping, form, request, response)); //484
} catch (Exception e) {
return (processException(request, response,
 e, form, mapping));
}

}

It seems like it is trying to do the right thing.

H..

The default impl of the execute method is as follows:

public ActionForward execute(ActionMapping mapping,
 ActionForm form,
 ServletRequest request,
 ServletResponse response)
throws Exception {

// Call the deprecated method for backwards compatibility
return (perform(mapping, form, request, response));

}

As you can see it just calls the perform method.

The perform method(s) are no ops.

I searched the entire code base for the words... Method perform() not yet
implemented. Nothing!

Are you sure you are not subclassing a custom Action class?


Wait... I see... dag nabbit a closer inspection of the stack trace
reveals.

Conclusion:

Your execute method is getting called... it is the one throwing the
exception.

com.faid.qa.actions.viewDataAction.execute(viewDataAction.java:19)

Send the above line of code with surrounding code.

Conclusion:

Your execute method is getting called... it is the one throwing the
exception. (Or the exception gets thrown when it executes a helper object).

See... com.faid.qa.actions.viewDataAction.execute(viewDataAction.java:19)

Send the above line of code with surrounding code.


Thought process

Check the signature of you execute method. Perhaps the default execute
method is getting called.

Hmm.

I looked line 484 of the RequestProcessor (from the stack trace that you
sent).

protected ActionForward
processActionPerform(HttpServletRequest request,
 HttpServletResponse response,
 Action action,
 ActionForm form,
 ActionMapping mapping)
throws IOException, ServletException {

try {
return (action.execute(mapping, form, request, response)); //484
} catch (Exception e) {
return (processException(request, response,
 e, form, mapping));
}

}

It seems like it is trying to do the right thing.

H..

The default impl of the execute method is as follows:

public ActionForward execute(ActionMapping mapping,
 ActionForm form,
 ServletRequest request,
 ServletResponse response)
throws Exception {

// Call the deprecated method for backwards compatibility
return (perform(mapping, form, request, response));

}

As you can see it just calls the perform method.

The perform method(s) are no ops.

I searched the entire code base for the words... Method perform() not yet
implemented. Nothing!

Are you sure you are not subclassing a custom Action class?


Wait... I see... dag nabbit a closer inspection of the stack trace
reveals.

Conclusion:

Your execute method is getting called... it is the one throwing the
exception.

com.faid.qa.actions.viewDataAction.execute(viewDataAction.java:19)

Send the above line of code with surrounding code.

Re: New to struts, having an issue

[David Erickson]

Bret,
I'm using execute in all of my actions.  You are implementing the execute
action properly in your viewDataAction action class correct?  Also you are
properly extending Action?  Posting some source code might help.

redirecting to fully qualified hostname

[Fullam, Jonathan]

All,

The application I am working on is secured with a login that required a
username and password.  Once a user is logged in, all pages can be accessed
as long as there is a Subject object in the Session.  My problem is that
part of the webapp provided links to pages that open in another window, and
when the link is clicked, it is forwarding to the logon page as if the
Subject object is no longer in the Session.  I've determined that this
behavior is only present when the hostname used for the request is not fully
qualified upon the intial logon.

For instance.

User logons on by going to http://serverName/webapp/logon.do

Then the application provides a link to
http://serverName.mycompany.com/webapp/something.do which open a page in a
new window.

When the user click the link, a new window is opened but they are forwarded
to the logon page as if they never logged on in the first place.

How can I have all requests to the original hostname
http://serverName/webapp be redirected to
http://serverName.mycompany.com/webapp ?  Is there anybody out there that
has experienced this or knows of a better way to work around this issue?

Thanks in Advance,
Jonathan

RE: ActionForm - redirect to custom JSP after validation failed

[Christian Schlaefcke]

Thank you for your advices! That helped improving my understanding of
struts alot! At first glance I like the aproach with "validate=false" and
calling the validate method myself in the LoginAction class, so I have the
control when to validate.

Regards,

Chris

Don't know how i had it working before but does now. Thanks man..

Re: mapping question

[Daniel H. F. e Silva]

Vanessa,

  As discussed a time ago on this list, it is considered a best pratice
to go through an action all the time. So you can decouple your view layer
in a way that makes your life easier. There are plenty of learning resources
around the Internet about Struts, but i'd like to recommend www.reumann.net
and www.ibatis.com. iBATIS is where you'll find a nice implementation of PetStore
sample application that could be useful as a starting point to your apps.

Cheers,
 Daniel Silva.

PS: If you need help during your day you could go to #struts_users IRC channel at 
irc.darkmyst.org
You'll meet nice people and very skilled java and struts developers there.

Tag library versioning

[Barnett, Brian W.]

I'm a little confused on how tab library versioning works. When I run my
Struts web app, the resin console fills up with SAXCompileExceptions,
complaining about " is an unexpected element" and "
is expected", etc., etc. My app seems to run fine, but I'd like to resolve
this issue.  Not sure what to. Can someone give me some guidance here?

 

Thanks.

 

Re: Multiple Beans one Action

[Mark Lowe]

you can store one in the session,

FirstForm beanA = (FIrstForm) form;
SecondForm beanB = (SecondForm) session.getAttribute("beanB");
Or nest beanB in beanA or vice versa.

AFAIK Struts is only going to populate one Form bean from one request.
But if your forms are session scoped you can retrieve any of them in the
Action code with session.getAttribute().

Not knowing a thing about your design, is it possible that this is one
of those apps that would benefit from having a single big Form bean with
all the properties, and then each HTML form may only use a subset?

I also don't see why BeanUtils can't handle turning multiple request
parameters with the same name into an ArrayList.  It *seems* like it
should work.
String[] works fine for me, though.  I actually thought there was a
one-liner to turn a String[] into an ArrayList of Strings, but I was
mistaken-- Arrays.asList() only produces a fixed-length list.  You can
change values, but you can't add a value to the array-backed-List.  My
"issue" is probably not one that you have-- I need to accept input from
three text areas and manually add the concatenated text to the String[]
property.
It would be nicer to do it with myList.add( "stuff" ), but since I can't
get ArrayList to work, here's how I'm using String[] in Action code:
  DynaActionForm dForm = (DynaActionForm) form;
  String[] accounts = (String[]) dForm.get( "accounts" );
  String fund = dForm.getString( "fund" );
  String function = dForm.getString( "function" );
  String costCenter = dForm.getString( "costCenter" );
  String[] newArray = new String[ accounts.length + 1];
  System.arraycopy( accounts, 0, newArray, 0, accounts.length );
  newArray[ newArray.length - 1 ] =
fund+"_"+function+"_"+costCenter;
  dForm.set( "accounts" , newArray );
  accounts = null;
  return mapping.findForward( "advanced" );
I haven't used arrays in ages, so if someone is now ROFL at my
incredibly inefficient code, please enlighten me.

Re: Bothersome BeanUtils.populate exception

[Mark Lowe]

Additionally i don't get the exception when i remove sizes and colours  
from the form, as i was getting mystical bean utils errors I started  
doing split half debugging like one does with javascript.

Everything's fine except for these properties. As I said before I've  
had this working in this way, there just must be something that i'm  
missed (although I'm fecked if i can see it).

My guess us that the exception happens when struts creates a dynabean  
from my action form, and/or attempts to populate the form based on the  
information it gets about the bean. But my types match as far as i can  
see.

The only thing i thought it could have been was stuff being stored as  
objects in the arraylist, I've had this working for weeks with  
arraylists.

I've updated beanutils in case that was the issue and googled for other  
folks with the same problem . to no avail.

Subject: Bothersome BeanUtils.populate exception
beanUtils keeps getting its knickers in a twist when i submit a form
with 2 select menus with multiple values. I've had this working before
with the same version of struts and commons. Its not the action as the
exception is thrown before i get that far, when i remove the menus the
form submits fine.
I have form properties of type arrayList. I;d expect this exception if
i were to be using unsupported types but I've been setting the values
with  String and the form properties are also of type string.
I have trouble believing that bean utils has an issue with converting
Object to String when the values are copied.
The exception is a typical beanutils chocolate fire guard exception.  
If
i weren't using strings i'd understand but i am.

Any insights welcomed.

RE: ActionForm - redirect to custom JSP after validation failed

[Dhaliwal, Pritpal (HQP)]

I generally like to stay away from using login.jsp AND a failure.jsp. Mainly
because its two different pages to maintain, when they look very similar.

So use just login.jsp for both just simple login, and failure.

I would suggest that in your DisplayLoginAction or similar, set a request
attribute like isDisplayLogin that tells you that it is not a failure. If
after validation failture you are being forwarded to login.jsp ,
isDisplayLogin will not be set. Now you can render the jsp with your failure
stuff. 

I am not a Struts expert, but my feeling is that you SHOULD be checking if
user has entered login and password, but you SHOULD NOT be checking if that
combination is right in the FormBean. That SHOULD be done in the Action, so
you can decide what to do next..

My authentication filter is not implemented using struts, so I don't use the
above scenario myself, yet.

My 2 cents..

First, the behavior experiencing is as designed. I suggest getting a good
book on Struts geared for Struts novices like Professional Struts published
by Wrox (written by James Goodwill and me).

You can turn validation off in the action mapping (action element in the
struts config file) by setting the validate attribute to false (the default
is true).

That said

Here is what I would do (and have done in a similar situation).

Turn validation off by setting validate=false on the action mapping:






Have the action's execute method calll the validation method of the
ActionForm, then forward to anywhere you would like.

ActionErrors errors = form.validate();

//if errors not empty forward to failure
return mapping.findForward("failure");

Subject: ActionForm - redirect to custom JSP after validation failed


Hi Folks,

I have a simple login.jsp that I want to validate. So I have a Class
"LoginForm" with a "validate" method, that fills up the ActionErrors with
the errors that might occur (missing username/password, wrong
username/password). Later the execute method of the corresponding Action
class "LoginAction" checks those ActionErrors. If not empty I try to return
a forward to "failure.jsp".

The problem I have is that before my LoginAction could execute my custom
forward the RequestProcessor of Struts tells in the logs, that validation
has failed and request will be forwarded to /login.jsp (which is of course
the input item of this action in struts-config.xml). When a validation error
occurs my LoginAction class is never called.

I searched the archive of this list already but couldn´t get through the
solutions I found there. I still don´t understand why this is happening and
what I can do to redirect to a custom failure.jsp.

Could someone please explain in newbie-style ;-) ?

Thanks & Regards!

Re: Using ArrayList instead of String[] properties

[Mark Lowe]

The only issue with using arraylist as a form property is to scope to 
session so you can change the size when required. I tend to use them 
for nesting beans rather then just storing strings.

My form parameters are in an arraylist. I just think beanUtils hates me 
or something rational like that.

I also don't see why BeanUtils can't handle turning multiple request
parameters with the same name into an ArrayList.  It *seems* like it
should work.

String[] works fine for me, though.  I actually thought there was a
one-liner to turn a String[] into an ArrayList of Strings, but I was
mistaken-- Arrays.asList() only produces a fixed-length list.  You can
change values, but you can't add a value to the array-backed-List.  My
"issue" is probably not one that you have-- I need to accept input from
three text areas and manually add the concatenated text to the String[]
property.  

It would be nicer to do it with myList.add( "stuff" ), but since I can't
get ArrayList to work, here's how I'm using String[] in Action code:

  DynaActionForm dForm = (DynaActionForm) form;
  String[] accounts = (String[]) dForm.get( "accounts" );
  String fund = dForm.getString( "fund" );
  String function = dForm.getString( "function" );
  String costCenter = dForm.getString( "costCenter" );
  String[] newArray = new String[ accounts.length + 1];
  System.arraycopy( accounts, 0, newArray, 0, accounts.length );
  newArray[ newArray.length - 1 ] =
fund+"_"+function+"_"+costCenter;
  dForm.set( "accounts" , newArray );
  accounts = null;
  return mapping.findForward( "advanced" );

RE: ActionForm LifeCycle (Maybe a bug in Struts)

[Richard Hightower]

Understanding the lifecycle of an ActionForm...

The ActionServlet handles requests for Struts, i.e., requests ending in *.do
is common. The ActionServlet looks up the RequestProcessor associated with
the module prefix. The RequestProcessor implements the handling of the
lifecycle and uses RequestUtils as a façade to Servlets scopes.

When a form gets submitted, Struts looks up the action-mappings for the
current request path from the ModuleConfig. The ModuleConfig is the object
manifestation of the struts-config.xml file, each module gets its own
ModuleConfig. (Recall that the action attribute in the html:form specifies
the path of the action to invoke.)

Struts locates the form-bean mapping from the action-mapping associated with
the request path. (This occurs in the processActionForm method of the
RequestProcessor by calling the createActionForm method of RequestUtils.)
If Struts does not find an ActionForm in the scope specified by the
action-mapping, it will create an instance of the ActionForm identified
form-bean mapping.

Struts populates the ActionForm by mapping the request parameters from the
HTML form variables to the JavaBean properties of the ActionForm instance.
Before it populates the form, Struts calls the reset method of the
ActionForm. (This occurs in the processPopulate method of the
RequestProcessor by calling the populate method of RequestUtils.)

If validation is required and is successful an instance of the Action class
execute method will be invoked. Validation is required if the validate
attribute of the action mapping is not false (the default is true). If
validation fails, control will be returned to the submitting form (the input
JSP) where the JSP form fields will be populated by the ActionForm. The
ActionForm is valid if the validate method returns null or an empty
ActionErrors collection. (This occurs in the processValidate method of the
RequestProcessor.)

The best way to understand the lifecycle is read the source code for the
RequestProcessor.

Hi All,

I was wondering if anyone knew what the lifecycle of an ActionForm is?
The reason I ask is in regards to the display of variables with a
.

I have noticed that the values displayed within a  are values
after a reset() method has been called,

*** The reset method gets called on each request. Your job is to populate
the form either in the reset method with default values or populate the
actionForm in an action and forward to the JSP page that has the html:form
to populate application specific (look up in a database).

and not after a validate method is called.

**Validate is for form submission not a mechanism to populate a form. You
are not using the validate method correctly.

Can anyone tell me the reason for this, as I seem to think this is a bug
within the Struts framework.

** Sorry. It is not. You need to get a good book on Struts I suggest
Professional Struts by James Goodwill and me. ;)


An example follows as to what I am talking about (based upon the following
ActionForm):


// Example ActionForm
public class MyActionForm extends ActionForm {
private String maximumDocuments = "3";
...// More variables


public MyActionForm() {
super();
System.out.println("Constructor called");
}



public void setMaximumDocuments(String maximumDocuments) {
this.maximumDocuments = maximumDocuments;
}

public String getMaximumDocuments() {
return maximumDocuments;
}
...// More get/set methods


public ActionErrors validate(ActionMapping actionMapping,
HttpServletRequest httpServletRequest) {
ActionErrors errors = new ActionErrors();

System.out.println("validate called");
System.out.println("before processing maximumDocuments: " +
maximumDocuments);

if(maximumDocuments == null) {
maximumDocuments = "50";// The supposed default value (if no
value entered)
}

 BAD MOJO

System.out.println("after processing maximumDocuments: " +
maximumDocuments);
...// Say an error has been returned
return errors;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
System.out.println("reset called");
System.out.println("before processing maximumDocuments: " +
this.maximumDocuments);

this.maximumDocuments   = "50";

System.out.println("after processign maximumDocuments: " +
this.maximumDocuments);
}

beanUtils keeps getting its knickers in a twist when i submit a form
with 2 select menus with multiple values. I've had this working before
with the same version of struts and commons. Its not the action as the
exception is thrown before i get that far, when i remove the menus the
form submits fine.

I have form properties of type arrayList. I;d expect this exception if
i were to be using unsupported types but I've been setting the values
with  String and the form properties are also of type string.

I have trouble believing that bean utils has an issue with converting
Object to String when the values are copied.

The exception is a typical beanutils chocolate fire guard exception. If
i weren't using strings i'd understand but i am.

Any insights welcomed.

Re: ActionForm - redirect to custom JSP after validation failed

[Kris Schneider]

If I understand what you're asking, try setting validate="false" in your action
mapping so that validation is deferred to your action. Otherwise, Struts will
perform validation automatically and, as you've noticed, never invoke your
action if there are errors.

Another option would be to keep validate="true" (that's actually it's default
value), but change input="/failure.jsp" (or wherever else you want to forward
upon validation errors - it can even be another action).

RE: ActionForm - redirect to custom JSP after validation failed

[Richard Hightower]

First, the behavior experiencing is as designed. I suggest getting a good
book on Struts geared for Struts novices like Professional Struts published
by Wrox (written by James Goodwill and me).

You can turn validation off in the action mapping (action element in the
struts config file) by setting the validate attribute to false (the default
is true).

That said

Here is what I would do (and have done in a similar situation).

Turn validation off by setting validate=false on the action mapping:






Have the action's execute method calll the validation method of the
ActionForm, then forward to anywhere you would like.

ActionErrors errors = form.validate();

//if errors not empty forward to failure
return mapping.findForward("failure");

RE: Transaction tokens

[Richard Hightower]

OK this is a bit of an Obligatory plug but

The "Professional Struts" book written by myself and James Goodwill covers
this step by step.
First it lists the steps. Then it breaks the code down by each step.

You will want to have you saveToken called just before the form loads for
the first time.

Here is a scaled down excerpt

To use a transaction token, follow these steps:
1.  Before you load the JavaServer Pages (JSP) page that has the html:form
tag on it, call saveToken inside an action.
2.  When the user submits the form, call isTokenValid and handle the form
only if the token is valid.

The first step is to call saveToken inside an action. To do this, you have
to make sure an action is called before the JSP page loads.

Let’s say you had an action mapping that was associated with the user
registration page as



The above just associated a JSP page with an action. Then any JSP page that
links to the input form would link to it like this:

User Registration

Therefore, no JSP links directly to /userRegistration.jsp. If this is the
case, you have been following the rules in the MVC chapter and it is easy to
start using transaction tokens.

Now let’s say that you want to make sure that the user cannot hit the back
button in the browser and submit the form twice. To do this, you must change
the action mapping associated with the input form to map to an action that
will call the saveToken method of Action:



  


Action’s saveToken method generates and saves a transaction token and puts
it in session scope under the key Globals.TRANSACTION_TOKEN_KEY. Think of a
transaction token as a unique string.

Notice that the action mapping for userRegForm sets the parameter to load.
The action will use the parameter to load the form.

We already have this action defined. Thus, we need to modify the
UserRegistrationAction so that it can handle loading the form by calling
saveToken:

public class UserRegistrationAction extends
 LookupDispatchAction {

private static Log log =
 LogFactory.getLog(UserRegistrationAction.class);


public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
log.trace("UserRegistrationAction.execute");

if ("load".equals(mapping.getParameter())){
return load(mapping, form, request, response);
}else{
 return super.execute(mapping, form,
 request, response);
}
}

private ActionForward load(
   ActionMapping mapping,
   ActionForm form,
   HttpServletRequest request,
   HttpServletResponse response)
  throws Exception{
log.debug("In LOAD Method");
saveToken(request);
return mapping.findForward("success");
}


Let me know if this helps.

Re: ActionForm - redirect to custom JSP after validation failed

You could forward (not redirect) to a generic failure page if there are 
errors present. I confess i haven;t done this but it could be what you 
want, even forward to a global forward defined in struts config, so you 
can reuse you error page for other stuff.

Re: mapping question

[Mark Lowe]

You can do either but i always use an action and forward to the jsp.

The only really objection not to routing your request through a mapping 
is that you expose your jsp's to the user. But this often isn;t a 
problem for some folks.

If you want to pre-populate your form then you can map the form to the 
referring action so you can mess with it before the user is forwarded 
to the form.

Dipak,

Are you certain that the filter will be invoked on the /j_security_check
request when container-based security is used? I have not tested this, but
it would not surprise me to find that some containers do not execute filters
on /j_security_check requests. I don't know if the Servlet Spec says
anything about this case.

Chris,

Another alternative to the original problem of security with "remember me"
functionality will be available soon. A patch has been submitted to my
SecurityFilter project (http://www.securityfilter.org/) to support "remember
me" functionality. The integration should be complete soon, and a beta
release will be made available once the integration is complete.
SecurityFilter works very much like container-managed security otherwise,
including the configuration format (except that you declare the constraints
in a separate config file rather than web.xml).

bean utils seems to be complaining that the types in my form and those 
in the form bean are somehow different, i cant see where.

It was working, until i rearranged a few things. A few 
questions/suggestions in help me problem solve would be greatly 
appreciated if you have the time.

Cheers Mark

Struts Tiles Double Post Issue

[Smith Justin M]

I am running into a problem with Struts Tiles.  My action class is being executed 
twice when I submit a page.

I have a simple page like this. 

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>




It executes the action that I define in my struts config.  


http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";>




   




 






  


   

   











I am seeing the second execution happen when the   
line gets called in the layout.jsp file. 

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

























 



























 

Any ideas why this is happening?

Is this normal?

Here is my tiles def xml file...


http://jakarta.apache.org/struts/dtds/tiles-config.dtd";>
  






   
  





   



   


Thanks...

Justin

How to use html:link using modules and tiles

[C.Aussems]

I started using modules in my struts application, but have difficulties with
links defined in a default tile.

In my default app tiles-defs.xml I have defined a base layout which is being
extended in my module tiles-defs.xml.

The base layout puts a header, menu , body & footer

 
 
 


The body put is defined in module tile def

 


My menu has a link to the catalog module 

To switch between module contexts I have to use a SwitchAction,
which I like to define as least as possible, so in default app's
struts-config.xml


 

 
 

In the default applications pages all goes well, but in any module page I
get the folowing error
[ServletException in:/common/pages/menu.jsp] Cannot create rewrite URL:
java.net.MalformedURLException: Cannot retrieve ActionForward named
/catalog'

I tried te resolve this using different Html:link attributes and so on,
but it seems I have to define all menu links as global-forwards in all
modules ??? with contextRelative="true"
and map those to the the switches in default app's struts-config.xml or even
worse define them also in all modules ??
I can't believe this because then somehow all the modules are coupled and we
dont't want that, so i'm missing something, but what ?

Re: Using ArrayList instead of String[] properties

Using arrayList as a form property works fine with action forms dyna or 
otherwise. In fact IMO it makes like simpler. As i recall you were 
trying to iterate through a map of forms not an arraylist.

Re: Pagination Support

[C.Aussems]

The Pager Tag Library is the easy and flexible way to implement paging of
large data sets in JavaServer Pages (JSP). It can emulate all currently
known paging styles with minimal effort. It also includes re-usable index
styles that emulate the search result navigators of popular web sites such
as GoogleSM, AltaVista® and Yahoo!. The Pager Tag Library does most of the
work for you by dynamically organizing your data set into pages and
generating a browsable index with virtually any look desired.

Bothersome BeanUtils.populate exception

[Mark Lowe]

beanUtils keeps getting its knickers in a twist when i submit a form  
with 2 select menus with multiple values. I've had this working before  
with the same version of struts and commons. Its not the action as the  
exception is thrown before i get that far, when i remove the menus the  
form submits fine.

I have form properties of type arrayList. I;d expect this exception if  
i were to be using unsupported types but I've been setting the values  
with  String and the form properties are also of type string.

I have trouble believing that bean utils has an issue with converting  
Object to String when the values are copied.

The exception is a typical beanutils chocolate fire guard exception. If  
i weren't using strings i'd understand but i am.

Any insights welcomed.

RE: Using ArrayList instead of String[] properties

[Robert Taylor]

Wendy,

If you simply want to present a list of options to the user represented as
check boxes
and collect the selected options, and the selected options are just single
string values,
then you can do the following:

Define accounts property as an java.lang.String[] and initialize it to {}.



Retrieve you options and store them in an ArrayList named "accountOptions"
and render the options like so:





This should generate HTML like:





The servlet container will collect these values and place them in a single
String array under
the "accounts" name.

Struts will reset your form and them populate the accounts property of your
form with the String array.

Unless I've missed something, I don't see the need to using indexed
properties here if the selected value is single String and order doesn't
matter.

Implementing the equals method on an ActionForm

[Potter, Ivor]

I have encountered a problem where the equals method was implemented on an
ActionForm to return true under very loose conditions (ie two similar
objects would be regarded as equal).  This however broke our JSPs which were
then unable to fetch properties from the form bean.  Removal of the equals
method fixed the code again.
 
Does anyone know why this occurred - I have examined the source code for the
html tags and cannot see any point at which it would rely on the equals
functionality.
 
Cheers
 
Ivor

what does you form bean look like (dyna or otherwise)?

I lied, that doesn't work at all.  It produces HTML like this:

I read that indexed properties only work with logic:iterate, so I'm
trying to change over from logic:forEach.  Can someone help me sort

This works to generate HTML, but BeanUtils can't populate the

that is the 'accounts' property of accountForm because the bracketed

I'm getting the feeling that the things in the ArrayList property of

I already used the struts  tags successfully, but I'm having
trouble now inside a "moduled" application. The problem is that the
template tags seems to insert the module prefix before the path of the
jsp template file, which I would not, also because I thought the jsp
pages could/should not necessarily fit into a module, but could be
shared between modules. Every part of the struts framework seem to allow
this (note for example the contextRelative attribute in struts-config),
but the template tag seem not to do so. One solution is to put my jsp
inside subdirectories with the same names as modules, but as I said I'd
like to share some jsp between modules... Should I pass to tiles ??? I
don't need a complicated templating library so i'd prefer to simply use
template taglibs, but if tiles helps ... Any help is VERY appreciated.

ActionForm LifeCycle (Maybe a bug in Struts)

[Rodney Paul]

Hi All,
 
I was wondering if anyone knew what the lifecycle of an ActionForm is?
The reason I ask is in regards to the display of variables with a .
 
I have noticed that the values displayed within a  are values after a 
reset() method has been called,
and not after a validate method is called. Can anyone tell me the reason for this, as 
I seem to think this is a bug
within the Struts framework.
 
 
An example follows as to what I am talking about (based upon the following ActionForm):
 
 
// Example ActionForm
public class MyActionForm extends ActionForm {
private String maximumDocuments = "3";
...// More variables


public MyActionForm() {
super();
System.out.println("Constructor called");
}



public void setMaximumDocuments(String maximumDocuments) {
this.maximumDocuments = maximumDocuments;
}

public String getMaximumDocuments() {
return maximumDocuments;
}
...// More get/set methods


public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest 
httpServletRequest) {
ActionErrors errors = new ActionErrors();

System.out.println("validate called");
System.out.println("before processing maximumDocuments: " + maximumDocuments);
 
if(maximumDocuments == null) {
maximumDocuments = "50";// The supposed default value (if no value 
entered)
}

System.out.println("after processing maximumDocuments: " + maximumDocuments);
...// Say an error has been returned
return errors;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
System.out.println("reset called");
System.out.println("before processing maximumDocuments: " + 
this.maximumDocuments);
 
this.maximumDocuments   = "50";

System.out.println("after processign maximumDocuments: " + 
this.maximumDocuments);
}
}

 
 
SCENARIOS:


 

LIFECYCLE 1: From a previous page to a form which uses this ActionForm
 
The following output gets displayed:
 
Constructor called
reset called
before processing maximumDocuments: 3
after processing maximumDocuments: 50
 
RESULT: Here the value displayed in the form is 50 for maximumDocuments   (Correct)

 
--
LIFECYCLE 2: If an error occurs within the ActionForm (and the value 1 has been 
entered for maximumDocuments)
 
The following output gets displayed:
 
Constructor called
reset called
before processing maximumDocuments: 3
after processing maximumDocuments: 50
validate called
before processing maximumDocuments: 1
after processing maximumDocuments: 1
 
RESULT: Here the value displayed in the form is 50 for maximumDocuments(Incorrect 
as it should be 1)
--
 
 
 
Can anyone please tell me why this is happening, and how to correct this problem.
 
Cheers
Rodneyt Paul

Re: Using ArrayList instead of String[] properties

[Mark Lowe]

In the logic-el:iterate you defined the bean to scope with the id 
attribute, but then don't reference it in the form element



I'd consider not storing the formbeans in a map as you don't need to 
get the values out with a key. I provided an example of how to do this 
in this thread even making an arrayList of dynaactionforms will work.

RE: Mandatory use of form rather than request object

[Shishir K. Singh]

Aaah...but these are not related to form actions and are more like query
strings. I guess in this case, request.getParameter would still be  the
best bet, rather than trying to go for an overkill with the hidden id
field  etc etc ...just my thought. 
 
If you still don't want to request object, you may have a hidden form
with a hidden field. With onclick, you can call a java script function
to update the hidden field and then submit the form. Never tried this
though with links.

Like

Of course the a links are generate by struts. Then how couldthe form be
used in this case? 
I can think of using a hidden field in a form, and then on click, change
the hidden value to the id, and call the form submit.

Hi,
I understand that the request.getParameter should not be used when the
info is readily available in the 'form' object. But can we really take
it out? When I create a list of records in a table, with links to each

No. He would provide setters in the form for anything that needs to be
passed along in request scope. This has the dual advantages of type
safety and making the design more explicit to anyone reading the code.

This precludes you from storing data in the request scope, though - so
you're left with only storing things in the session scope, which I
wouldn't consider ideal.

Right?

RE: Mandatory use of form rather than request object

[Patrick Cheng]

Hi ,
Can you elaborate a bit?  The situation in my mind is, a jsp page with a
list of records, but no form at all.
Like
Orange

Of course the a links are generate by struts. Then how could the form be
used in this case? 
I can think of using a hidden field in a form, and then on click, change
the hidden value to the id, and call the form submit.

Rgds,
Patrick.

Filters are *not* required to be invoked on j_security_check invocations.  In
fact, Tomcat won't even enable the "j_security_check" url unless an
unauthenticated user accesses a protected resource.  Basically, I believe there
is no guaranteed-to-be-portable way to implement "remember me" functionality on
the server using container managed security.

Yeh, your right though. Taking it out is a bit drastic and the request
object tends to be needed for various other things as well so denying access
to it is probably going to cause other problems.

Best thing really is to reeducate the developers. (Electric shocks work
wonderfully here - though  best check that your company doesnt have an OHS
policy against it first ;-> )

RE: Mandatory use of form rather than request object

[Richard Hightower]

H this is a good point.

In the past I have created a map wrapper that wraps the request object and
session object and passed those as well.
the advantage is that the execute method is a little easier to test since it
does not rely on the servlet API.

The execute method would look something like this:


protected abstract String execute(ActionForm form, Map request, Map
session);

The string is the name of the forward. Again, the advantage from a TDD
perspective is I can easily write tests for the above.

I think I have an example of this approach in the Mastering Tomcat book (I
wrote about 1/5 of that). I do not have an example of this in the
Professional Struts book, but there would be if I had the often elusive more
time.

I was thinking of taking the approach in the ProcessAction from scaffold and
the PicoContainer (or something of that ilk), and doing something similar
with more of an IOC (just as soon as I get some more time).
