RE: How to turn off validation momentarily

[Albert Wong]

Shouldn't that be a separate "ConfirmDeletionAction" with it's action
mapping validate set to false?

If you wanted to combine multiple actions in one Action Handler but have
that action having auto-validationof formbeans you might try:
1.  Subclassing ActionServlet and overriding it's processValidate method
to not validate if a flag is sent in the HttpRequest (possibly a hidden
variable indicating "confirmDeletion". 
2.  Make your formBean's validate method check for the "do not validate
flag".

In struts-config you can specify that validation won't occur on a
per-action
basis like this:

How to turn off validation momentarily

[Tom Miller]

Hello

Is there a way to turn off form validation momentarily, say for just one
action.perform() invocation? I've tried placing a
mapping.setValidation(false) in various places in my "edit" and "save"
actions (a la struts-example). Basically, I do not want to validate a
record that I'm presenting to the user in order to confirm a delete, but
the form is set up for validation, so that gets executed too. But we're
deleting, so why bother?

Thanks in advance for any tips.

Re: Server Side Validation not firing for Validator when Java Script is off

[David Winterfeldt]

If you look at the jsType.jsp, you will see that it is
referencing an external JavaScript file called
staticJavascript.jsp.  You could put other JavaScript
methods in that and call them from onclick, etc. 
Although I'm not sure if that is what you mean. 
Otherwise you could do an xml include.  I think the
JavaScript associated with a java method should be
with it in the xml file.

beans:write bug?

[Bud Gibson]

We have a bean with properties where the setter takes a float, and the 
getter returns a string.  Using expressions and scriptlets, this all 
works fine.

For instance, I can write the following for a bean contained inside another:

<%= HagBean.getProduct().getPrice() %>

and a formatted string with the price will appear.  However, when we try 
the equivalent bean:write,



struts tells us that we are mismatching types with a float and String.

Is this a bean:write bug?  As I understand beans, setter methods are not 
even required.  I find it odd that bean:write seems to be assuming the 
type of the setter method and then becoming unhappy when it gets the 
type returned by the getter method.

Thanks,
Bud

Application Server Restart

[Pathangi, Rao H.]

Iam trying to deploy a struts application on Websphere Application Server
3.5 Patch 2. Could some one explain what happens from a Struts Point of view
when we restart the application Server.

I think that the webapp is being started and in the process the servlets
will be added to the container. Now since the webapp failed to start there
is no way I can test the servlets or JSP.

I see the following text in the application log. What could possibly be
wrong?

(Checked with the kwicprototype.webapp file in servlets directory, it seems
to be OK)

Re: Server Side Validation not firing for Validator when Java Script is off

[Scott Ryan]

Yes the javascript is being generated.  I think the problem is that I
used the validation.xml that comes with the latest release or your
validator and some of it appears to not be compatible with Netscape
version I am testing with.  Java script has the great benefit of failing
but not indicating where the problem is.  

I stripped out all but the required and mask code and it works.  

I can now go through function by funtion and see which one is
incompatible.

Is there any stratgy that would allow you to reference javascript that
is in a library so that we could use some of the current javascript
libraries we have today with out copying the code into the
validation.xml.

My next challenge is to get the generated validation to work with the
formatting javascript I currently have on the page.  This is currently
causing some issues.

Thanks for the help.

Problems with Struts on Weblogic 5.10 sp9

We are facing some strange problems. The code that runs on Tomcat is not
running on Weblogic.

We are using Tomcat server on local development machines and Weblogic 5.10
(sp9) on Development server. Further, we are using Struts model for our
project. We have observed that the code that runs smoothly on Tomcat has
some problems while running on Weblogic. They are as follows:

1. The URL gets modified: The 'wls' inside the URL disappears when a request
is submitted. We have traced the cause of this problem to an entry in
config.xml. When ever we have 'redirect = true' in the action mapping, the
URL gets modified. If we remove 'redirect = true', then the URL does not get
modified.
However, all our control logic is based on 'redirect = true', which works
well on Tomcat.

2. Struts architecture requires FormBeans to be associated with each view
component (JSP). On Tomcat, when a page is submitted, corresponding FormBean
gets updated. However, on Weblogic, the FormBean is not getting updated.
(In fact, only one out of some 70-odd parameters is getting populated in the
FormBean. This is strange - but true!)
We are NOT using custom tags in the JSPs. We are using simple jsp:usebean
and then access each property using its getter method.
We have all setter methods as required.

Any help on the above would be greatly appreciated.

Regards,

Sujit

Subject: Question: Struts on Weblogic - Urgent please 

Hi, 

I am using Struts on Weblogic 5.1 with SP9. 

Initially I developed my app on Tomcat. Here, I am forwarding control to 
another action object. So, in my config.xml, I have: 

 

I start my app on Tomcat through URL: 
http://localhost/wls/cmweb/detrunselect.do. When I submit this page, the new

URL I get is: 
http://localhost/wls/cmweb/detcontrol.do. 

This is the expected behavior. 

However, when I try to run the same on Weblogic, the second URL comes up as:

http://localhost/cmweb/detcontrol.do. 

Please note that 'wls' get dropped from the URL. This causes the app to 
fail. 

If I remove the 'redirect = true' from config.xml, then the URL appears as: 
http://localhost/wls/cmweb/detrunselect.do 

Please note, that 'wls' is not dropped. But the action object has also NOT 
changed. This is not what I want. 

So, I want to use 'redirect = true'. Can some one tell me how can I still 
get the 'wls' while using 'redirect = true'? 

Thanks in advance, 

Sujit

Re: More to say about setTransactionIsolation and mysql?

[Ted Husted]

The Berkley versions of the mySQL tables are suppose to support
transactions and rollback, but don't have several other features
available in the trusty myISAM tables. So that might be what you are
seeing.

I have since heard that using the Early Release rowsets for anything but
the simplest updates may be unreliable regardless of what DBMS you are
using. Seem solid on retrievals though, and that's 80% of it ...

Eventually, some other vendor will provide a better RowSet
implementation, and hopefully these problems will go away. For now, I'm
burying the fact I'm still using Statements for updates deep in my Data
Access objects, so I can switch over when that brave new day comes ;-)

Re: Begginer: how do i know what button is clicked from a strut form

[William Jaynes]

If your jsp has a submit tag like:



then your Action would contain something like

String okButton = request.getParameter("OK");
if (null != okButton) { ...code... }

However, RESET and CANCEL are generally something different. A standard reset
button is handled by the browser. The standard cancel button can be detected by
a call to isCancelled(request).

Re: Server Side Validation not firing for Validator when Java Script is off

[Scott Ryan]

I located the problem.  It was a combination of two things.  

1) The names in my form  and the validation tag did not match.  I had
two of them matching but all three needed to match.

2) I was using the .5 build which has an imcomplete validation.xml file
and the format has changed since that build.

Once question I have for those developing enterprise applications is
how to managed the validation.xml file.  It seems that is contains
application specific information as well as enterprise specific
information.

It seems that the file contains javascript validation code which could
be used throughout the enterprise on a number of applications. It also
contains validation rules specific to the application that you are
deploying.  It seems that you either have to duplicate the javascript
code to deploy in multiple validation.xml files or you have to include
the validation rules for all applications in every validation.xml file. 
I realize you can cut and paste but this opens up possibilities for
making mistakes.  

Has anyone come up with a way to package the inline javascript so it
can be used in multiple validation.xml files and you only have to change
one file to add additional javascript functions.

Concurrency with ActionForms

[Kevin McLain]

Does anybody know how Struts handles concurrency when it uses Reflection to
update ActionForm attributes? I am assuming that it doesn't but this can be
problematic if, in the case of a web application, you have two browser
windows - for the same session (this can de done in IE but opening a new
browser window from inside a current one) - accessing the same session
object concurrently. Just wondering

Cheers,

AW: getSession in xxxForm

[Holger Wiechert]

HI,
I'm having the same problem (and saw this posting right after I've put mine in).
Yes, getting the ActionServlet let's me access the ServletContext, but then I'm even
further away from getting the request that caused the ActionForm to be created, or do 
I see this wrong?

Well, I guess, that I could do something like: having always a different ActionMapping 
"in front"
of the one, where the ActionForm will be created. Within this pre-executed Action I 
use the same Form
(and have access to the request), change the Form according to the request and forward 
it to  the
real Action (just the first idea I had).

But isn't there a way of accessing the request somhow directly from within the 
constructor of the Form?

Re: Access to HttpServletRequest within ActionForm

[Erik Hatcher]

Look at the ActionForm's reset method.   That gives you the request and is
called when its instantiated by the ActionServlet prior to population from
the request.

One note - reset is not currently called when instantiated from the
 tag unfortunately, but apparently this will be alleviated in the
near future.   I'll submit a patch for this eventually if Craig doesn't get
to it first.

RE: html:errors tag?

[David Winterfeldt]

Ignore what I said about the logic tags since that
doesn't tell you whether a specific field has an
error.  You could use the errorsExists tag from my
Validator package if you want to though.  And you
could make errorsNotExist version of the tag.

Re: html:errors tag?

[David Winterfeldt]

You can check if there is an errors object in scope
using the logic tags to change the color of a label.

  
red label1
  
  
blue lable2
  

If you want to display the error message next to a 
field, you can do this.  This will display all error
messages that have been set for the 'name' property.

I'm wondering what people are considering best practices for JDBC calls?

I have been writing beans that wrap a database table, and include functions
"select", "insert", "delete". These functions either load the bean, insert
the bean values in the database, or delete the record from the database. In
all of these functions, I pass in a database connection from the action. (Or
whatever else is calling the bean.)

ie- public boolean select(Connection cn1, String primaryKey)

How are others doing it? I think this is a good approach, but want to see if
someone has come up with something better.

Thanks,

Hi - I just did this in my form.

html:errors itself doesnt do this. My actionform holds the   row and column

what i do is check if the error object exists and if the row and column

is it possible to do something like this with struts:

I have a form with labels for the input fields.
These labels have the font color blue.

The Form is validated by the FormBean.
When one or more fields of the form are invalid
and the control is forwarded back to the input form,
the labels of the invalid input fields should have the font color red.

In general, is it possible to output one text and in case of an error

Re: Server Side Validation not firing for Validator when Java Script is off

The JavaScript part shouldn't have anything to do with
the server side other than it uses the same object in
application scope.  Does the name attribute of your
action (which matches the key the ActionForm is stored
under) in the struts-config.xml the same as the form
element's name attribute?

Thus there are no examples and in relation to the sutruts-examples
either as on open the .java file in a editor (notepad) the code is

Thus Pls point me were i can check or obviously download again.As this

Re: Editing and Saving a Form

[dsf65b y b3763476b3]

Hi there!  [Windows NT, VAJ 3.5.3 WTE]


I'm trying to use the approach from the "struts-example" application to edit 
and save a form. The user is directed to "editInfo.do" which populates the 
form and forwards to "editinfo.jsp" which, on submit (starting a new 
request?), invokes the "saveInfo.do". But when I enter the perform method of 
the Action object associated with the "saveInfo" mapping a new form has been 
created and I can no longer access the values from the editInfo form. I can 
see that it hasn't merely been cleared (ActionForm.reset(...)) because I 
dump it to stdout.

I brutally 'clipboarded' the code from the struts-example app (see bottom of 
message) so I'm having a really really hard time trying to understand why it 
wont work! If you could offer any advice I would be extremely grateful.

Is the standard way to operate a multi-lingual web app to have different

Indexed properties with multiple select options

[Michael Terry]

Hi -

In my JSP I'm generating (a small unknown number) of multiselect
SELECT drop-down lists with values taken from a Hashtable containing
ArrayLists, such that each drop-down corresponds to the strings in
an ArrayList in the Hashtable:

  <% int n = 0; %>
  
<%
  prop = "attributeKeys[" + n + "]";
  n++;
%>


  

  

In the associated form bean, I assume I need to use an ArrayList (named attList
below) which will contain the String[] arrays of selected values passed back
from my SELECTs. So I have my indexed property String[] attributeKeys with
getter and setter thus:

public String[] getAttList(int idx) {
return (String[])attList.get(idx);
}

public void setAttList(int idx, String[] keys) {
attList.set(idx, keys);
}

But the problem is that this collapses in BeanUtils.populate with a
type mismatch error:

  javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:486)
  Root cause: 
  java.lang.IllegalArgumentException: argument type mismatch
at java.lang.reflect.Method.invoke(Native Method)
at 
org.apache.struts.util.PropertyUtils.setIndexedProperty(PropertyUtils.java:688)

I'm quite new to Struts, and can't understand what I'm doing wrong!
Is it actually possible to use multiple select options with indexed
properties? Any ideas? Thanks!

RE: Where do YOU put JDBC calls?

[Pathangi, Rao H.]

Well, I too thought about this...

Then I thought, If I leave the getConnection() open and let the DAO take
care of it, I thought the same DAO can be used for multiple datasources. The
way you get a connection does not matter.

Well, I am still 50/50 about this idea though. I am thinking of another
approach

Lets say I have an abstract class DAOFactory.(A factory that creates DAO's)

so now My ABCDaofactory extends DAOFactory. (ABCDaoFactory is a singleton)

In ABCDaoFactory, i write an init method which sets the connection
Manager(It could be an Oracle manager or a DB2Connection manager).

Also, the ABCDaofactory  has a method getMyBottleOfPicklesDao() which
returns MyBottleOfPicklesDao (A data access object).

This factory would get you a ready made DAO and all you got to do is use
it.(Bruce Eckel calls these people who use these as Client Developers Hee
ha!!)

The MyBottleOfPicklesDao would extend a BAseDAO which has a concrete (not
abstract) getConnection method which says 

abstract class BaseDAO 

getConnection()
{

// This way you delegete the getConnection in the base class and that
connection depends on the Connection Manager //which is another layer of
abstraction that is set in the ABCDaoFactory.
conn = connectionManager.getConnection();// the connectionManager
variable is set in the factory
}

this way your DAo doesnt need to know how to get a connection

This is a nice pattern, but I do not want my DAO to be responsible for
getting the connection. I need to use them in the web-tier (no EJBs) and
possibly also the middle tier. In each case the DataSource may be obtained
in a different manner and it is not the DAO's responsibility to know how.

To handle this situation, I wrote a base class which has the connection
Object as a protected variable. Lets say you have a method readOrder(String
orderId)..

Write another abstract method getConnection() in your BaseDAO. Use
connection manager or pooling or whatever, but get a connection in this
method and implement it in your DAo that extends the BaseDAo

Now in the method readOrder can read something like this

readOrder(String OrderId)
{
try
{
   Connection con = getConnection(); // Your DAO is now plugged
   // Do something with the connection...   

}
catch{}
finally
{
//close connection, unplug your DAO
}
}

ditto.
I am always reading that the Connection reference should be passed into the
method. After writing a few DAOs in this manner, I found the exception
handling too tedious - I was checking for closed connections both within the
DAO method and also in the calling method. So I usually pass in a DataSource
and ensure that my DAO method obtains and closes the connection. Shoot me
down if you like.

Subject: Where do YOU put JDBC calls?



I'm wondering what people are considering best practices for JDBC calls?
 
I have been writing beans that wrap a database table, and include functions
"select", "insert", "delete". These functions either load the bean, insert
the bean values in the database, or delete the record from the database. In
all of these functions, I pass in a database connection from the action. (Or
whatever else is calling the bean.)
 
ie- public boolean select(Connection cn1, String primaryKey)
 
How are others doing it? I think this is a good approach, but want to see if
someone has come up with something better.
 
Thanks,

Server Side Validation not firing for Validator when Java Script is off

[Scott Ryan]

I am trying to use the Validator extension for struts.   I have the
client side functioning correctly and it works great.  I then go into
Netscape and turn off java script and the server side checking is not
firing.  Am I missing some configuration parameter?  I even tried
calling super.validate from a validate method within my ActionForm and
this returned no information either.  Any ideas on where I can look?

Thanks

RE: Where do YOU put JDBC calls?

[Ryan Cornia]

From my understanding then - 
 
I would have my Business Object class that wraps the table, 
lets call it Address.
I would have a DAO object that is specific to that Business 
object for the JDBC calls, lets call it AddressDAO.
 
In Address, I would have loadAddress, DeleteAddress, 
InsertAddress, all of which would call AddressDAO to do the actual JDBC 
call?
 
Any simple examples of these two classes that are not EJB's? 
Is this the route to go if I'm not using EJB's?
 
Thanks,
Ryan

RE: Where do YOU put JDBC calls?

[Geddes, Mark (ANTS)]

This is a nice pattern, but I do not want my DAO to be responsible for
getting the connection. I need to use them in the web-tier (no EJBs) and
possibly also the middle tier. In each case the DataSource may be obtained
in a different manner and it is not the DAO's responsibility to know how.

To handle this situation, I wrote a base class which has the connection
Object as a protected variable. Lets say you have a method readOrder(String
orderId)..

Write another abstract method getConnection() in your BaseDAO. Use
connection manager or pooling or whatever, but get a connection in this
method and implement it in your DAo that extends the BaseDAo

Now in the method readOrder can read something like this

readOrder(String OrderId)
{
try
{
   Connection con = getConnection(); // Your DAO is now plugged
   // Do something with the connection...   

}
catch{}
finally
{
//close connection, unplug your DAO
}
}

I am always reading that the Connection reference should be passed into the
method. After writing a few DAOs in this manner, I found the exception
handling too tedious - I was checking for closed connections both within the
DAO method and also in the calling method. So I usually pass in a DataSource
and ensure that my DAO method obtains and closes the connection. Shoot me

Please ignore my statement "the Business Object calls the DAO's business
methods". It need not always do that.
You could implement a factoryObject that does it for you and by using a
factoryObject you can maintain the anonymity between the Business Object and
the DAO.

Re: Bug?

[suhas]

suppose u have something like this in Jsp


In this case u need not to mention the name and type attribute for the
 tag
But  there should be some action mapping in the struts-config.xml file which
points to form to be used .
I mean






So when the  gets parsed it will
definitely try to look for form ("myForm") based on the struts.xml file .

Where do YOU put JDBC calls?

[Ryan Cornia]

I'm wondering what people are considering best practices for 
JDBC calls?
 
I have been writing beans that wrap a database table, and 
include functions "select", "insert", "delete". These functions either load the 
bean, insert the bean values in the database, or delete the record from the 
database. In all of these functions, I pass in a database connection from the 
action. (Or whatever else is calling the bean.)
 
ie- public boolean select(Connection cn1, String 
primaryKey)
 
How are others doing it? I think this is a good approach, but 
want to see if someone has come up with something better.
 
Thanks,
Ryan

Subclass ActionServlet to behave as central controller

[Peter Severin]

Hi ppl,

Would it be possible to subclass the ActionServlet to add behaviour
needed for it to behave as central controller so it could handle all the
requests coming to the web application, not only the action execution
requests ? In the subclassed ActionServlet I want to be able to add some
logic which will determine where the request should be forwarded in case
where isn't any action to be processed by ActionServlet. For example a
request for /example/some_page.do could be forwarded to /some_page.jsp
OR /WEB-INF/jsp/some_page.jsp. I don't want to add mappings in
struts-config.xml for each page I have in the application.

Peter.

Re: Ant Q regarding deployment of jar's

[Calvin Yu]

I wouldn't do this.  What kind of jars are you dealing with?  If the
jars are used by Ant to run tasks, then put them in ANT_HOME/lib.  If
they belong to your project and only required to build your project, I
would recommend putting them in a 'lib' directory under your project
directory.  You could put them in C:\jars, but that might cause some
confusion later on if you're building different projects with
conflicting libraries in C:\jars.

Not sure I fully understand but here goes...

When form.jsp starts generating the HTML for the form, it will look for
an ActionForm from which it can get default values. The name it will
use to look for this bean is defined in the struts-config.xml under the
Action to which you will be submitting the form. So the ActionForm name
is associated with the Action that receives it rather than the JSP that
generates it. So the fact that the JSP that generates it is wrapped
inside a frame isn't really an issue.

There are at least two other possible problems, though:

1) If you want the previous Action to preload the ActionForm with
   some information (from a database, for example) you can do
   this by making your own ActionForm bean, filling it in, and
   then saving it in the session scope under the name which is
   declared in the Action that will receive it. It will then be
   found automatically when form.jsp generates the HTML.

2) If you choose to automatically validate the ActionForm, you
   need to specify the "input" page so that Struts can
   automatically send you back there in case of an error. I don't
   have experience with this but you should be able to specify
   your frame.jsp file as the input source. When it then
   renders form.jsp within, this inner page will still find the
   ActionForm in the context if it were the highest level page.

Does that help?

Re: Displaying errors when validating forms (ActionErrors)

[Hartmut Bernecker]

OK, thank you, I got it!

I don't understand it, but the problems seems to be the place oft the
 tag within the JSP. I placed it at the end of the 
element with bad result. When I moved it top to the  element it is
ok. May be there is a problem with the html in the jsp-document ...

Do I am allowed to ask another question:
If I want the error-keys not to have in the main ressource-file
(web.xml:)
( ...

... )
but in another separate file using 
,where do I have then to deploy the asim-form-validation.properties

Re: Displaying errors when validating forms (ActionErrors)

[Guus Holshuijsen]

Hartmut,

I do it at the end of an action's perform() method using the "construction"
given in my previous reply!

What I describe is only valid if your controller checks for errors itself.
In case you let Struts handle the validation automatically, I advice you to
look at the Struts source code.
The following code snippet is from the Action.java class:

/**
 * The request attributes key under which your action should store an
 * org.apache.struts.action.ActionErrors object, if you
 * are using the corresponding custom tag library elements.
 */
public static final String ERROR_KEY = "org.apache.struts.action.ERROR";

Concluding: the errors are stored in the request (session?) attribute
"org.apache.struts.action.ERROR".

Guus

html:img questions

[Jake Thompson]

Hi all,
I'm new to the list, so sorry if this has come up before.

When I use the  or , it
will encode the session id into this a cause the images not to load.  Is
there a fix or am I doing somthing wrong?

Thanks in advance,
Jake T.

Using Frames within STRUTS

[Alexander, Glynn (LIT)]

Hi,
I would like to make use of frames within my STRUTS application but am
unsure how the framework handles frames.  For example, if I have a form
within a JSP page (form.jsp) and that page is presented to the user within a
frame (frame.jsp), how should I associate the ActionForm to the form.jsp
within the struts-config.xml file.  I want the app to navigate to the
frame.jsp page but cannot associate the ActionBean to this jsp as it does
not have a form tag.  Is there a recommended solution ?

Thanks in advance for any help

Hello & Best Practises Question

[Emaho, Ghoot]

Hi,
 
I have a question regarding what the community would consider to be Best
Practises when using Struts. I am doing an internal review of our own
usage of Struts within our products, and I have constructed an example
application to highlight my question(s) and talk around. I would
appreciate any feedback, insight or help that the community can offer.
 
I appreciate that this question requires a bit of effort on the readers
part ! Hopefully I have explained the context in enough detail to
solicit decent responses, but not so detailed as to tire you out !
 
Most Web Applications perform similar tasks which could be considered
generic regardless of domain. I have taken some of these tasks and
bundled them into this simple example. The example is a simplification
of an application I am building at the moment - a Struts based Wiki
called 'ChiKi'. For those who are not aware of what a wiki is, refer to
http://www.c2.com/cgi/wiki?WikiWikiWeb
  for details.
 
Given an object that is to manipulated, core tasks that could be
performed on that object would include

*   View
*   Edit
*   Save
*   Create [not considered in example]
*   Delete [not considered in example]

In this example, we have the object is called 'Page' which has 'id' and
'content' as string attributes. I wish to be able to View, Edit, Save,
Create and Delete 'Pages'.
 
So here are some of my questions  - all implementation details can be
found at the end of the email:

*   given the details of the components and the xml configuration at
the end of this email, how does this implementation compare to how you
would do it ? i.e. what other ways would people 'configure' to achieve
the same end result ?
*   are there any given Best Practises that could apply ?
*   other areas to consider could include:

*   separation: save and edit could be encapsualted in the same
action, would you ?
*   Page & EditForm: essentially the same, how would people avoid
duplication ? or would they bother ?
*   usage of request scope
*   ...

I appreciate that this is a simple example, but I would like to get a
feel for how people would do this, and ascertain if there are differing
strategies - and the various pros/cons of each strategy.
 
It is my intention to offer up the full blown ChiKi as an example app
for Struts development once it is ready, and I would like to be able to
take feedback from this post into account. This will hopefully be useful
for developers using Struts - it's always helpful to have other ex
amples ! and it will certainly be used internally for my developers
training/introduction to Struts - as well as actually being used within
our development team as a tool - wiki's are great :)
 
[We are about to release v1.0 of our current Struts based application -
a large enterprise application globally deployed for a large
multinational. I will post more details about this as I'm sure there is
interest in Real World developments. Of particular interest may be the
results from our Performance testing, the overall Architecture and so
on. This may be one of the largest and certainly most complex Struts
based applications to go into production, and I would like to share the
experience with the community. More details to follow shortly]
 
So thank you for making it this far, and if you have any feedback at
all, please let me know. 
 
Many thanks
 
Ghoot Emaho
Development Team Leader
Petrotechnics Ltd  

 

In the implementation, I have the following components:

*   Page.java

*   simple bean with accessor methods for 'id' and 'content'
attributes

*   ChikiService.java

*   provides methods getPage(String pageId) and setPage(Page p) to
be used by the Actions

*   View.java

*   extends Action
*   accepts 1 request parameter 'pageId' which uniqely identifies
the page
*   requests Page 'pageId' from ChikiService
*   puts the returned Page object into the request
*   returns a forward to View.jsp


*   View.jsp

*   displays the Page object in the request, using:

*   
*   

*   provides a hyperlink to 'Edit' this page:

*   Edit


*   EditForm.java

*   simple bean with accessor methods for 'id' and 'content'
attributes
*   identical to the 'Page' object, except it extends ActionForm

*   Edit.java

*   extends Action

*   accepts 1 request parameter 'pageId' which uniqely identifies
the page
*   requests Page 'pageId' from ChikiService
*   populates EditForm with values from the returned Page Object
*   returns a forward to Edit.jsp


*   Edit.jsp

*   displays the page to be edited. 'id' attribute is a text label
and the 'content' is in a text area which the user can edit and then
submit to be saved

*   






*   Submits the EditForm to the 'Save' action for processing

*   Save.java

*

Re: Displaying errors when validating forms (ActionErrors)

[Hartmut Bernecker]

No, I think I did not!
My validate Method looks like that, it returns Errors back to the
controller servlet.
- Where is the place to save the errors in the request???


   public ActionErrors validate(ActionMapping pMapping,
HttpServletRequest pRequest)
   {
  System.out.println("VALIDIERE");
  ActionErrors errors = new ActionErrors();
  if (iBenutzer == null || iBenutzer.length() < 1)
  {
 errors.add("benutzungsname",
 new ActionError("error.login.benutzername.required"));
  }
  if (iPasswort == null || iPasswort.length() < 1)
  {
 errors.add("passwort",
 new ActionError("error.login.passwort.required"));
  }
  if (iSprache == null || iSprache.length() < 2 ||
iSprache.equals("blank"))
  {
 errors.add("sprache",
 new ActionError("error.login.passwort.required"));
  }

  return errors;
   }

html:text filter=false

["Schröder, Veit"]

Is there any way the to prevent the html:text Tag from filtering 
the value? Like the bean:write filter=false?

Thanx Veit
 

RE: Displaying errors when validating forms (ActionErrors)

[Firmin David]

It might be worthwhile doublechecking the "input" attribute in your xml
mapping for the request URI you're handling.
If there is no input page specified, the ActionServlet will not know which
page to return control to in order to display the errors it receives from
the validate() method.

Re: Displaying errors when validating forms (ActionErrors)

Do you save your errors?

// Report any errors we have discovered
if ( !errors.empty() )
{
  saveErrors( request, errors );
}

500 Servlet Exception

[Stanley Tan]

Hi, I get a 500 servlet exception when trying to access 
"struts-example".  I am using Resin 2.0.1.  What could be wrong?  On Resin 
1.2.3, it does work but not on 2.0.1.

What should I do?

Thanks!
