RE: Converting a ResultSet to a List of POJOs
You could also consider using Torque. I believe it will generate a schema
from an existing database that will allow you build a set of data aware
objects. It also some good classes for working directly with XML. I wrote
a simple Struts plugin to work with Torque. It's not as cool as Hibernate
but it may get the job done and the code base has been around a while. I
have been using it for over two years and have a good luck with it.

Subject: Re: Converting a ResultSet to a List of POJOs
We wrote something like this at work:
ResultSetTransformer is an interface with a single method:
public Object instanceFromRow(java.sql.ResultSet rset) throws
java.lang.Exception;
We mostly use a single implementation of the interface which we call
SimplePropertyMappedTransformerYou set the bean class when you
construct the SPMT, and then for each call to instanceFromRow, it
creates a new instance of the bean class and calls the following:
protected void populateBean(Object bean, ResultSet rset)
throws java.lang.IllegalAccessException,
java.lang.reflect.InvocationTargetException,
java.sql.SQLException {
Map properties = new HashMap();
ResultSetMetaData metaData = rset.getMetaData();
int cols = metaData.getColumnCount();
for (int i = 1; i = cols; i++) {
String value = rset.getString(i);
if (value == null) {
value = ;
}
log.debug(property: + metaData.getColumnName(i) + ,
value: + value);
properties.put(metaData.getColumnName(i), value);
}
BeanUtils.populate(bean, properties);
}
This assumes that you can alias the column names in your SQL to
property names. This works fine in Oracle, but I'm not very expert
on the differences between ANSI SQL and Oracle SQL. If you had to,
you make a version which also takes a Properties which mapped column
names to bean property name.
Then we have another layer which takes a SQL string and a
ResultSetTransformer and is responsible for managing the connection,
executing the query, and iterating through the

- Original Message - From: Rick Col [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, September 06, 2003 4:12 PM Subject: two actionForms for one action class? Hi, Is there any way to use two action forms for one action class. I have the following situation: one html form (form1) and a go button for sample1.jsp, another html form (form2) and submit button for sample2.jsp. Once user clicks on go button, she will be directed to sample2.jsp, form1 values will be used and displayed on sample2.jsp. Once user clicks on submit button on sample2.jsp, form2 values should be saved to database. I need to desgin one action form (actionForm1) for form1 to be retrived and displayed on sample2.jsp, and design another action form (actionForm2) to be retrieved and saved to database. Thus, the action class I design for sample2.jsp needs two actionForms. I am wondering there is any way to set up two forms for one action class (in struts-config and elsewhere)? One way to do this is to assign actionForm1 to a property in actionForm2 in the Action1.execute() method: ... ActionForm2 form2 = new ActionForm2(); ... form2.setForm1(form1); // put form2 in the expected scope for sample2 action mapping ... return new ActionForward(/sample2.jsp); Then you could use the nested properties in form1 for possible display in the sample2.jsp. And save them, if desired, in the Action2.execute() method.

RE: Any potential drawbacks with this design
The difficulty with extending the RP occurs if not ALL the actions need this common functionality. Where this is the case your design is a good one. (I have used it to great effect in my own apps already). Id suggest you continue with this method. If you have other developers on the project make sure they know to extend your class if they need that functionality. You might also wish to declare the execute() method in your base class final so that they dont inadvertantly override it. -Original Message- From: Ted Husted [mailto:[EMAIL PROTECTED] Sent: Monday, 8 September 2003 17:25 To: Struts Users Mailing List Subject: Re: Any potential drawbacks with this design This is a common approach that many application use.

Struts action in the login-config
I've been exploring the co-mingling of container-based security and struts actions through FORM-based authentication. While many options have been presented and discussed (including subclassing the Action and directly calling container-managed security methods), it seems to me (a newbie) that one obvious solution has not been addressed: What are the side-effects of directly pointing the error and login pages directly to a struts action (in the example below /login.do) , rather than to an HTML or JSP file? For example: login-config auth-methodFORM/auth-method form-login-config form-login-page/login.do/form-login-page form-error-page/loginError.do/form-error-page /form-login-config /login-config And in the view of the login form: form method=POST action=j_security_check Username: input type=text name=j_usernamebr / Password: input type=password name=j_passwordbr / /form If this won't work, what about pointing the login and error pages to a JSP, and using a logic:forward or a tiles:insert tag in the file to handle the request through struts? Am I missing something subtle (or not so subtle)? Thanks in advance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I'm interested in folks response to this also. This is the approach I have used on 2 different projects and seems to work very nicely. In addition, I modified the signature of my abstract method (in this case executeTask) to take a custom ActionForm with some additional functionality.

Re: Any potential drawbacks with this design
There is no *drawbacks* or *advantage* design in regard to extending Action or RequestProcessor. It depends. The key is how you actually interpret the word common: -If the *common* functionality is applicable to *all* action mappings in a given application module, you do it by extending RequestProcessor. For example, a custom security checking facility in RequestProcessor. -If the *common* functionality is required to happen before certain logic you do it by extending RequestProcessor. For example, a custom form token checking facility before the form bean population. -If the *common* functionality is applicable to a sub set of Action classes in the application module, then you do it by extending Action. For example, a CRUD operation for a set of business entities. And you also give other developers a way to interpret the CRUD operation differently when they see fit.

[OT] How to get an object stored in ServletContext from a SessionBean?
Hi,
I know this is a bit OT, but here it is: any help is much appreciated.
This relates to the Hibernate Plugin for Struts..
How do I get a handle on the SessionFactory that is stored in the ServletContext??
(From a SessionBean, that is)
The following is a shortened (an uncompiled!) version of how the SessionFactory is
stored...
Colm
import org.apache.struts.action.PlugIn;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
import java.net.URL;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
public class HibernatePlugIn implements PlugIn
{
public void init(ActionServlet servlet, ModuleConfig config)throws
ServletException
{
Configuration configuration = null;
URL configFileURL = null;
private SessionFactory factory = null;
ServletContext context = null;
configFileURL = new URL (/hibernate.cfg.xml);
configuration = (new Configuration()).configure(configFileURL);
factory = configuration.buildSessionFactory();
context = servlet.getServletContext();
context.setAttribute(SessionFactory.class.getName(), factory);
}
}

image property
Hi,
The struts documentation of attribute property for image tag says that
The property name of this image tag. The parameter names for the request
will appear as property.x and property.y, the x and y representing the
coordinates of the mouse click for the image. A way of retrieving these
values through a form bean is to define getX(), getY(), setX(), and setY()
methods, and specify your property as a blank string (property=)
The image tag does not have a name or id attribute. If I have more than one
image tag in a form how do I differentiate one getX() from another? For
example, let consider that I have two image tags in my form. The ActionForm
has the following lines
public class MyForm extends ActionForm {
private String x;
public String getX(){
return(this.x);
}
..
Following the documentation how do I get the value of x in my JSP page? And
how do I differentiate x values for the two image tags?
Thanks in advance

Are you sure the value isn't getting reset before it gets to your page? I
assume no exceptions are being thrown which prevent the field from
initializing, I saw earlier you're initializing this value in the
constructor. What happens if you just leave the value assigned from the
private instance var and have the accessor retrive that w/o the stuff in the
constructor?
html:image src='%= MapForm.mapSource() %' property= /
From your example, I also assume you retrieved the MapForm object from the

simple question
Hi all, I think I have a relative easy question. I have a J2EE application which has some entitybeans. I want to display the values of these entitybeans in my JSP pages (using Struts). I have made value objects of the entitybeans. In my ListAllCategoriesAction.java, I do something like the following: Collection allCategories = mySessionFacade.getAllCategories(); DisplayBean displayBean = new DisplayBean(); displayBean.setCategories(allCategories); request.setAttribute(categories, displayBean); return mapping.findforward( SUCCESS ); As you can see I'm using a special bean (displayBean) to pass the categories to my JSP page. In my JSP page I use the logic:iterate tags to iterate through te collection and display the proper information. Is this a normal / good approach? Or do I have to use ActionForm classes for this purpose?

RE: Any potential drawbacks with this design
Jing sums up the situation well. One point to add :- if it (the functionality) is applicable to all the actions today and you decide to go with the RP approach, that doesnt mean that tomorrow you wont suddenly need to add an action to which it should NOT be applied - at which point you will then either have to factor it out of the RP into some base action anyway - or do it conditional on checking some flag - at which point you run the risk of introducing action logics into the RP... My votes with the Action approach :-) -Original Message- From: Jing Zhou [mailto:[EMAIL PROTECTED] Sent: Monday, 8 September 2003 21:20 To: Struts Users Mailing List Subject: Re: Any potential drawbacks with this design There is no *drawbacks* or *advantage* design in regard to extending Action or RequestProcessor. It depends. The key is how you actually interpret the word common: -If the *common* functionality is applicable to *all* action mappings in a given application module, you do it by extending RequestProcessor. For example, a custom security checking facility in RequestProcessor. -If the *common* functionality is required to happen before certain logic you do it by extending RequestProcessor. For example, a custom form token checking facility before the form bean population. -If the *common* functionality is applicable to a sub set of Action classes in the application module, then you do it by extending Action. For example, a CRUD operation for a set of business entities. And you also give other developers a way to interpret the CRUD operation differently when they see fit.

RE: simple question
Yes. This is a normal approach. ActionForms are used only if you want to pre-populate data. i.e If you have to show default values in a text field you can pre-populate the Action Form and forward to a JSP. You can also store a Collection directly in one of the scopes and show that but Custom beans like this are useful because they can be manipulated quite well with the tag handlers.

TMC Petshop, java performance tuning, struts
I have recently read the results paper from the second benchmark test run by The Middleware Company (TMC) comparing the performance of the Petshop application using Java solution and .NET solutions. (http://www.middleware-company.com/casestudy/tmc-performance-study-jul-2003.pdf) This paper would be very useful I believe to anyone who is interested in fine tuning the performance of their application and server. IMO the results paper seems to suggest that Java solutions can be just as fast as .NET solutions but that some Java solutions can be much much worse. In particular, a java solution using struts is unlikely to perform as well as a solution that does not use some form of introspection (as struts does to populate beans from forms). I have several questions regarding these conclusions. 1. Are they accurate based on the evidence presented in the study 2. Does anyone know the identities of the two java servers used in the study 3. In using struts does the productivity gains outway the performance cost and can this performance cost be adequately mitigated by upgrading hardware. 4. Have any similar tests been run in which the Java servers are run on Unix platforms instead of Windows Server 2003. 5. Has anyone performing tests on their own struts apps found similar results concerning the high costs of the introspection process. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I believe it's RFC 822.
Unfortunately, I think that's a valid email address as defined in the RFC.
You're better off writing your own. RFC 822 is very generous because it
doesn't just deal with remote internet addresses, but email from all sorts
of networks.
Here's an example of something that's a bit more restrictive.
This first runs it through javax.mail.internet.InternetAddress(). You'll
need to have the javax.mail package installed to use it.
Then it performs additional restrictions (we want to disallow local
addresses).
private boolean isRemoteAddressSyntax(String emailAddress)
{
int firstAtPos = emailAddress.indexOf('@');
int lastAtIndexOf = emailAddress.lastIndexOf('@');
int lastDotIndexOf = emailAddress.lastIndexOf('.');
// Must be one @
if (-1 == firstAtPos) return false;
// Must be at least one character before @
if (1 firstAtPos) return false;
// Must be at least one '.'
if (-1 == lastDotIndexOf) return false;
// Only one @ allowed.
if (firstAtPos != lastAtIndexOf) return false;
// '.' must be at least one character after '@'
if (lastDotIndexOf (firstAtPos + 2)) return false;
// Must be at least one character after '.'
if (lastDotIndexOf == (emailAddress.length() - 1)) return false;
return true;

Subject: image property
Hi,
The struts documentation of attribute property for image tag says that
The property name of this image tag. The parameter names for the request
will appear as property.x and property.y, the x and y representing the
coordinates of the mouse click for the image. A way of retrieving these
values through a form bean is to define getX(), getY(), setX(), and setY()
methods, and specify your property as a blank string (property=)
The image tag does not have a name or id attribute. If I have more than
one
image tag in a form how do I differentiate one getX() from another? For
example, let consider that I have two image tags in my form. The
ActionForm
has the following lines
public class MyForm extends ActionForm {
private String x;
public String getX(){
return(this.x);
}
..
Following the documentation how do I get the value of x in my JSP page?
And
how do I differentiate x values for the two image tags?
Thanks in advance

Are they accurate based on the evidence presented in the study I would presume they are accurately measured (have no way to verify), but the key to understanding this test is the description of the testing scenario. They spent a LOT of time tuning things so that the database and network were not bottlenecks; the goal being to measure the CPU time in the middle tier. While that's interesting, how often is it relevant in the real world, where database and network latencies are the normal bottlenecks to response time? 2. Does anyone know the identities of the two java servers used in the study Anybody who authoritatively answers that question is in big time trouble because it would break NDA agreements :-). 3. In using struts does the productivity gains outway the performance cost and can this performance cost be adequately mitigated by upgrading hardware. For the first part of this question, you need to determine if it even matters in your particular app. For the second part, it's mitigated by adding more/faster CPUs. 4. Have any similar tests been run in which the Java servers are run on Unix platforms instead of Windows Server 2003. I did some microbenchmarks on the commons-beanutils code that is in turn used by Struts -- see the message archives for the [EMAIL PROTECTED] mailing list and search for microbenchmarks. A couple of things my tests showed were pretty interesting: * When using BeanUtils.copyProperties() or PropertyUtils.copyProperties(), using a DynaActionForm (which uses a HashMap but no reflection) is actually faster than using standard ActionForm beans. * The BeanUtils.populate() method -- which is expressly tuned to deal with copying request attributes into your form bean -- is substantially faster than BeanUtils.copyProperties() is. * As expected, recent JVMs are substantially faster than earlier ones at reflection-based processing. 5. Has anyone performing tests on their own struts apps found similar results concerning the high costs of the introspection process. It can only possibly matter if CPU time on your middle tier server (the one running your webapps) is your response time bottleneck. Is it for you? If so, then this matters. If not, then it probably doesn't. IMHO, the most important single issue for performance of Struts based apps is the quality of your JSP page compiler. Just as an example, the Tomcat admin app is Struts based, and the difference between running it against an early 4.0.x version versus current 4.1.x or 5.0.x versions is night and day -- six times to eight times faster, and visibly more responsive even in a single user environment. If you're looking for performance improvements, in general you should focus on: * JDK you're running * JSP page compiler * Servlet container you're running * Database tuning * Network tuning before getting to the minutiae of CPU time comparisons for things like reflection.

RE: Create new nested bean instance
Ok, the thing I don't understand now is how to setup the AddNewPhoneNumber jsp so that is uses the lazy list to create a new PhoneNumber instance bean. I'm trying to use the nested taglib, but I don't really understand how to set the top level object to be a new instance out of the list. I've tried something like this: nested:nest property=phoneNumbers nested:text property=countryCode / nested:text property=areadCode / nested:text property=number / nested:text property=description / /nested:nest The thing I can't figure out is how you set the top-level object to be a new instance of the PhoneNumber bean (which should be created from the lazy list). I tried using nested:nest property=phoneNumbers, but that gives me an error stating No getter for property phoneNumbers.countryCode of bean customerForm. I figure that is because the nested:nest sets the top-level object to be the List, and doesn't actually attempt to get an item out of the list (which would cause the lazy list factory to create a new PhoneNumber instance). How is this supposed to work? Am I on the right track at all? Anyone have a link to an example like what I'm trying to do? Thanks. Nate On Mon, 2003-09-08 at 11:41, Robert Taylor wrote: Yep.

RE: Create new nested bean instance
Sorry Nate, I can't help you with updating your structures using the
nested taglib. I haven't done it before. Maybe someone else can provide
you some guidance there so that you don't have to jump through the
indexed properties hoops.
On the other hand, using indexed properties:
Your form must have getPhoneNumbers(int index) and setPhoneNumbers(int
index)
methods.
Ultimately you want the HTML syntax to be something like:
input type=text name=phoneNumbers[2].countryCode /
input type=text name=phoneNumbers[2].areaCode /
input type=text name=phoneNumbers[2].number /
input type=text name=phoneNumbers[2].description /
Where the index of 2 is the nth location for your new phone number.
You could pass 'n' as a request parameter when the user clicks on
the Add New Phone Number link.
Since the nth location doesn't exist, the lazy list will create an empty
PhoneNumberBean object and add it to the list in the nth location anytime
when a get() or set() is invoked on a location that does not exist.
This is all in the documentation which I'm sure you've read by now.
So one way to achieve the HTML syntax listed above, is something like
the following where 'n' is a request parameter named 'topLevelIndex':
%String prefix = phoneNumbers[ + request.getParameter(topLevelIndex) +
];%
html:text property=%=prefix + .countryCode%/
html:text property=%=prefix + .areaCode%/
html:text property=%=prefix + .number%/
html:text property=%=prefix + .description%/
There are more slick ways to do this using JTSL or Struts-el but if you just
want to
get it working first, you can try the above.
What should happen when your form is displayed is that the html:text .../
tag will
look up (finally delegating to PropertyUtils) the indexed properties and
attempt to get any existing value by invoking
the getPhoneNumbers{index). The List implementation provided by the lazy
list
will determine that no object exists at the specified location and it will
create an empty PhoneNumberBean object and populate the list and then
delegate to the
get(index) which will retrieve the empty bean property. This prevents the
dreaded
ArrayIndexOutOfBoundsException.
When your form is submitted, Struts sets the appropriate PhoneNumberBean and
then you can
procede with your business logic.
Nate, I hope this makes sense. Sorry I couldn' help you with using nested
taglib to accomplish
this. I assume you have already looked here:

Subject: RE: Create new nested bean instance
Ok, the thing I don't understand now is how to setup the
AddNewPhoneNumber jsp so that is uses the lazy list to create a new
PhoneNumber instance bean.
I'm trying to use the nested taglib, but I don't really understand how
to set the top level object to be a new instance out of the list.
I've tried something like this:
nested:nest property=phoneNumbers
nested:text property=countryCode /
nested:text property=areadCode /
nested:text property=number /
nested:text property=description /
/nested:nest
The thing I can't figure out is how you set the top-level object to be a
new instance of the PhoneNumber bean (which should be created from the
lazy list). I tried using nested:nest property=phoneNumbers, but
that gives me an error stating No getter for property
phoneNumbers.countryCode of bean customerForm. I figure that is
because the nested:nest sets the top-level object to be the List, and
doesn't actually attempt to get an item out of the list (which would
cause the lazy list factory to create a new PhoneNumber instance).
How is this supposed to work? Am I on the right track at all? Anyone
have a link to an example like what I'm trying to do?
Thanks.

Thanks for the links. I already read the Indexed Property FAQ (and I

The lazyList stuff looks more promising. I have a question about it,
though. Where do I create the new LazyList? In the
ActionForms reset()

[ANN] Internet IDE - Carrier 2.0 b2
A solid release of Netspread Carrier 2.0 b2 is available today. The Carrier client, a visual design environment on Internet, is tested with JRE 1.4.2 with performance surprising my VB friends. There are two new things I am very proud of: 1) A Form Token Facility is introduced to automatically protect every web form and every hyper link in application modules with no-cache turned on. The facility is completely hidden from the views of designers and can be turned on/off programmatically. 2) The Carrier Developer's Guide is near completed in which the LocalizedDate class is examined in details. The four key attributes, input format, output format, format pattern (or a key to the localized pattern), and error key, are completely encapsulated in the class. Therefore designers only need to register this class in a form bean property descriptor with desired format pattern or its key in ONE place. I see other methodologies make the designers to register input format here, output format there, pattern in another configuration file... causing endless troubles just for a simple Date property. Now the problem is solved in the cleanest way. It is a complete i18n java.sql.Date property to my knowledge and it tells us almost any other complex properties could be designed this way. See it with composing screen shots at http://www.netspread.com/developer.html#FormBeanValidations Carrier is designed to be used by sloppy users like many of us in this list. It doesn't tell you How easy to write codes to do it, instead, it tells you How easy to compose web forms to do it with the capability of CRUD operations for hierarchical and/or tabular data entries. It also tells you Where you put wrong things in case configuration errors occur. It is a solid commercial grade product for you to enjoy, no suffering. If you complain any parts of it, tell us. User experience is on top of the priority list.

RE: Struts 1.0 problem
We recently ported the weblogic server from SP1 to SP4 and
came accross the following problem while displaying the JSP
pages. This was working fine on SP1. Can anyone tell me the
possible reason.
The line of code in the jsp is :
bean:write name=%=formBean% property=name[53] scope=request/
where 53 is an input parameter of getName(int size) method of FormBean.
And that's the problem. The syntax above says that name is an array, and
that you want element number 53 of that array. That's exactly what the error
message is saying (Property 'name' is not indexed).
You could get around this with some more Java code :
%
String name = formBean.name(53);
%
c:out value=${name} /

book on JavaScript. Seemed to work OK at the time.

Is there a published specification on e-mail addresses?
I believe it's RFC 822.
The reason I
ask is
that we are using the 'email' validator, and it's
accepting as valid
e-mail
addresses such as 'u-+-+%^_/[EMAIL PROTECTED]'. I didn't think
Validator
would accept these, but apparently is it. If there's not an
established
spec for e-mail addresses, then I would assume that
anything goes
I believe that the name part needs to be quoted. However, I believe
currently validator will still
count this as a valid email. I haven't gotten around to
tweaking the
regexp. To handle these cases
the user name pattern/expression will need to increase in
complexity by
a factor of 3 or so.
How about an option that would allow only struct user names
checking,
ie [a-z][A-Z] and '.'.
+1 on the new option but I think the allowed characters should be
a-zA-Z0-9_.-
The clunky part is both the client and server
versions of the regexp
need to change. I believe I would actually like to make the
client side
checking more course,
ie allow any email in the form of [EMAIL PROTECTED], then let the
java take care
of full validation,
what do you think ?
+1. Javascript is merely a convenience for the user and it's
a pain to
maintain this complex logic in 2 places.

Unfortunately, I think that's a valid email address as
defined in the
RFC.

Subject: RE: Struts 1.0 problem
We recently ported the weblogic server from SP1 to SP4 and
came accross the following problem while displaying the JSP
pages. This was working fine on SP1. Can anyone tell me the
possible reason.
The line of code in the jsp is :
bean:write name=%=formBean% property=name[53] scope=request/
where 53 is an input parameter of getName(int size) method of FormBean.
And that's the problem. The syntax above says that name is an array, and
that you want element number 53 of that array. That's exactly what the error
message is saying (Property 'name' is not indexed).
You could get around this with some more Java code :
%
String name = formBean.name(53);
%
c:out value=${name} /

Subject: Why is No getter method for property happening... damn.
Hi gurus,
I got a simple bean below.
public class Company {
private static ArrayList list;
private int id;
private String name;
static{
list = new ArrayList();
list.add(new Company(0,));
list.add(new Company(1,MS));
list.add(new Company(2,SUN));
list.add(new Company(3,IBM));
list.add(new Company(4,SYBASE));
}
public Company(){}
public Company(int id, String name){
this.id = id;
this.name = name;
}
public int getId(){
return id;
}
public String getName(){
return name;
}
public static ArrayList getList(){
return list;
}
}
---
This bean is set into the application scope at tomcat starts.
sc.getServletContext().setAttribute(company,new Company());
In jsp, I try to get the bean like this.
logic:iterate id=id name=company property=list scope=application
bean:write name=id property=name/BR
/logic:iterate
It's supposed to be showen like
MS
SUN
IBM
SYBASE
but I get the following error.
org.apache.jasper.JasperException: No getter method for property list of bean
company
why ?? I cannot figure out...damn.
Thanks in advance.

indexed properties
The following article seems to differ in approach from how the posters
to this forum implement indexed properties in struts:
http://www.developer.com/java/other/article.php/2233591
In this article, the author uses a DynaActionForm which automatically
builds an array of normal beans. By normal, I mean that the beans
have methods like this:
String getFoo()
void setFoo(String foo)
rather than this, as is often advocated in this forum:
String getFoo(int index)
void setFoo(String foo, int index)
I prefer the former approach except for one minor factor: it doesn't
seem to work. :(
Struts seems to be creating me a valid form. I say this becuase I have
an iterator on my form that displays the right number of rows of text
boxes, and they all have names like mybean[0].foo. Furthermore, if I
change the property attribute of my html:text tag to bar, I get an
exception when I render the page that there is no bar property.
So things seem to be working well, up to this point, but in the
implementation of the action, my form bean doesn't have any values set.
They're not even blank; they're null. I stuck a println in a setter
method -- it's not even being called.
I can, however, see the values in the request parameters if I print them
out in the implementation of the action.
Help! Actual code follows.
Thanks in advance,

RE: Redisplaying of entered form fields
Hi Andrew,
All of my struts actions have the redirect flag as false.
Here is more of my configurtion code which is used to run the application I am running.
Would be most appreciative if you could have a look.
Cheers
Rodney
CODE:
Below the code you see is part of an application I am building.
The problem here lies in the fact that in all cases,
field data does not get redisplayed within the form the user has entered data in.
eg. if you enter a invalid data within a numeric data field (this instance ACN)
then the ActionForm issues a error message gets issued (works)
but the ACN previously entered does not get redisplayed in the form.
eg. if you enter a valid ACN or Organisation Name within the fields to do searches,
and no data is applicable to the search criteria entered a error message gets
issued (works)
but no ACN/Organisation Name gets redisplayed in the form where the data was
entered.

Re: why servlet as controller in MVC
That is kind of an open-ended question, but here are two alternatives and some problems associated with them: 1. Filter -- some containers require that a request really does map to a resource, so even if the Filter mapping matched the request you could end up with 404 errors in the case where the resource doesn't exist. One way to avoid this would be to have each request map to a JSP directly, but that would be pretty confusing if the controller decided to map the request to some other JSP (or some other, similar view resource) instead of passing it down the chain to the indicated JSP. Some Actions have some kind of switching behavior to route the request to one of a number of view resources. 2. JSP -- the controller normally passes the request to a view resource (like a JSP) but doesn't produce the response directly. JSPs are best suited to producing a response (usually HTML) directly, where a servlet better matches the needs of writing a controller. Other view-oriented technologies are similar to JSPs, and many use their own servlet to process the requests anyway. Since those don't work so well, a Servlet turns out to be a good match for the needs of the controller component in comparison. It sounds like you might have something else in mind -- what alternative implementation strategy are you thinking of? -Max On Mon, 2003-09-08 at 19:24, virupaksha wrote: Dear All, I have a simple doubt, Why servlet is considered as controller in in MVC framework, Can any one please answer..

Redisplaying of entered form fields

I have a problem redisplaying form fields a user enters within a html form.

matter.

RE: Searching facility questions
Well Mike, my problem is not to avoid user from accessing JSP directly, but to show her a list of links with a meaning as a result of a search action. The problem is even worst, if you think that I'm using Tiles, with the actual web content in JSPs which are never accessed directly neither by a Struts action, but imported as defined in the Tiles definition file. Did anyone realize a search facility which runs on a Struts application running Tiles? How did you solve the problem: content-linkable mappings? I'm thinking to create a configuration file with a mapping between the content JSP pages and meaningful Struts action links. The search facility will return a list of meaningless paths to JSPs containing the actual website content, and a class will search for the Struts mapping between those links and linkable actions. Does it make sense? (here he was looking around with a very interrogative expression...)
