Re: Tokens

[Matt Raible]

see the example app - they're used to track if the form has already been
submitted and such (back button and reload button issues).

The simplest way is:

then use

doing arithmitic ops

[Henrik Chua]

Hi!

I have a simple question.  Will I be able to produce a mathematically
calculated value based on the input given without another variable?
here's the scenario.
JSP page 1, I have an input textfield (num) and a submit button
on my form bean, I have a variable called num.
on my action form, it just forward to the JSP page 2  
on JSP page 2, I want to display in HTML format the value of num multiplied
by 3.

will i be forced to create another variable in the form bean , say total,
that will do the computation and store in that variable and display the
variable total on page 2.

should it be done that way?  or I can simply do the multiplication without
an additional variable?

thanx in advance.

Struts and returning NOCONTENT

Hi, in my application, after a specific post, I'm setting the NOCONTENT

incrementing, as thou its wanting data.  I don't have the exact code on me

similiar problem? (and solved it?)

Re: findDataSource

Tim,

I'm running MacOS X, Tomcat 4 too but with postgres RDBMS.  My 
datasource set-up in Struts config is diiferent though, I see yours is 
the same as the example given in the struts-example.  I lifted mine from 
the user guide and it works just fine.

   
 
   

I don't know which is valid or if they both should work.  (Still getting 
to grips with Struts1.0 so could be a feature of 1.1?).

Missing message for key index.title - Workaround

One way to workarounf the Tomcat security

Missing message for key index.title - Problem Found

[Frank Lawlor]

I found the problem, at least in my installation,
and maybe for others.

I have security turned on.  This causes all the
application accesses to local files (e.g.,
properties, struts-config.xml, etc.) to fail.
This isn't apparent since many of the methods
seem to silently swallow the security exception.

Unfortunately, I can't see how to fix this.
It should be possible to fix it by granting
permission in catalina.policy, but the spec
to give struts.jar permission, e.g.:
  grant codeBase
"file:${catalina.home}/webapps/struts-example/WEB-INF/lib/-" {
 permission java.security.AllPermission;
  };

doesn't work because of a Tomcat bug loading
libraries from /WEB-INF/lib.

Moving the lib to /common/lib also
seems to have problems with derived classes
in the /WEB-INF/classes classes.

Hi Chris,

Make sure you have getFlag() and setFlag() methods in your User bean. The
error says that it can't find the getFlag() method. In the example you gave
for property="name", I'm sure you have getName() and setName methods in your
User bean.

Hope this helps,

html:radio problems

[Christopher Book]

Hi,

I'm having a problem using the html:radio tag using another bean.

For my text fields, I define an object bean called "User" and set the value
using:


This sets the value of the text field to whatever the getName() method of my
form returns.

When I try to do the same thing with my radio buttons:
 true
 false

I get the following exception:
javax.servlet.ServletException: No getter method available for property flag
for bean under name User

I can use text boxes, selects, and textareas using this method and they all
work properly, so why does this not work with radio buttons?

Re: Is there a way to "call" a struts custom tag from your own custom tag?

Something like that. You would probably call the doAfterBody  in your own
doAfterBody, etc rather than one after the other, but yeah, that's the idea.

There might be another way to do this, but this is what I did.

RE: Is there a way to "call" a struts custom tag from your own custom tag?

[Hani Hamandi]

This is very cool!
And if the tag you're calling (ErrorTag in your case) were more complicated,
I would assume you would have to do the processing yourself, right?

In other words, in your case, you happened to match ErrorsTag by simply
calling its doStartTag(). But if, let's say, it implemented more methods
than simply doStartTag (like doAfterBody, doEndTag ..), you would probably
have to call these yourself one after the other, and check the return values
of each.

Thanks!

ErrorsTag errorsTag = new ErrorsTag();

If you need to pass info that won't be in the form, then I would think it perfectly 
acceptable to send it in the request using setAttribute(). There's no reason to 
clutter up your form code with getters/setters for data that your actions don't need.

Use a cursor. MySQL does it with:

Subject: Iterate Design Question


Consider a situation where you want to display a straght listing of items
from a database.  Something like where you would display a listing of 1-20
products on page 1, 21-40 on page 2, etc.  There seem to be two ways this
gets implemented.

1. Pull the entire table contents, store them into a container of sorts,
refer to the container's listing from page to page (instead of hitting the
database again.

2. Query the DB for only the contents you need on each request.  So user
request page 1, backend queries the the DB for products 1 - 20, returns it.
If the user requests for page 2, the backend does the same process over
again for products 21-40 and so on.

My specific situation prevents me from doing the first approach because the
result set is so large (takes too long to make that initial DB call)  and
the listing changes so often that it's possible a user may be view an
inaccurate listing.

In going forward w/ approach 2, I've been having some issues I'd like to
bounce off anyone w/ experience in the matter.
- Thought about using the PreparedStatement.setMaxRows() method, but if I do
something like "SELECT ... FROM Products WHERE...", I don't know if the
statement is smart enough to optimize itself to only retrieve 20 products.
The docs say that "the excess rows are silently dropped", but I don't know
if "silently" means it pulls all the records and only returns 20.  If that
is the case that would seem like I wouldn't get any performance gains (the
DB still has to go through the process of retrieving all the records).  I
imagine that what "silently" means would be dictated by the driver.

- I also thought about using database specific SQL statements to cap the
size of the result set (ie the 'Limit' keyword in MySQL).  This would be my
least desired step as I don't want to get tied to a specific database.  I'm
not aware of any ANSI SQL commands that will do this.

Anyone have any thoughts?

My first Struts question

[Knee, Jeff]

All,

I've just subscribed to the Struts Users mailing list, so "Hello, all!"

I also took the time to try to get the FAQ for the list and to find a
searchable archive but the mailing list faq is non-existant (according to
ezmlm).  I've looked at the Jakarta site and I'm still needing a push in the
right direction.

I'm building my first Stuts "app" to learn more about it and at the moment
I'm trying to use the html options JSP tag like so:





The action form for this JSP has the following method:

public ArrayList getOpponents()
{
PlayerController playerController = new PlayerController();

ArrayList list = playerController.getOpponents(ourName);

return list;
}


Unfortunately, I get the following error:

javax.servlet.ServletException: Cannot find bean under name opponents

If I manually create a list on the JSP and stick on the page context like
so:

<%
// ...
// create list
// ...

pageContext.setAttribute("opponents", list);

%>

...Then the page renders.

Am I missing something?  How can I get the options tag to find the
collection within the form?

look for the array in various places?  Perhaps I need to change

RE: Is there a way to "call" a struts custom tag from your owncustom tag?

[David Morris]

Hani,

I still must not understand, but I think that your someStrutsTag is 
indeed nested in your tag. At least the output is. You may be 
able to get away with something like:

if (getSomeStrutsTag() == null) {
  setSomeStrutsTag()(new SomeStrutsTag());
  getSomeStrutsTag().setParent(this);
  getSomeStrutsTag().setPageContext(pageContext);
  getSomeStrutsTag().setWhateverelse();
}
// You should probably use reflection to see what is available and then

// do something like this for the appropriate pieces:
getSomeStrutsTag().doStartTag();

You would put this code in the doStart or doEnd of your own tag. I
still 
don't think this is real good practice, but it should work.

The error is coming in ActionServlet.initMapping on the lines:

For some reason the getResourceAsStream() call is failing.  The xml file
IS there and I tried a lot of (valid) variations on the location and name

they all fail.  There seems to be something wrong with
getResourceAsStream().
Is this because it is in the init of the servlet?

There is a chapter each on Validator and Tiles. In addition, there is an

appendix on Validator and Tiles (the appendix is just a reprint of the

The full TOC is on baseBeans.net / book.

Nothing on Role Based Actions.

I do cover JDBC DB security realms (JAAS), XSLT, SQL/DB, etc.

I guess in a while there will be posts from readers who completed the 
book. Also news.basebeans.com / mvc-programers will have student reviews

of the people who took the class and read the book as well.

I will announce Amazon. They will cary it for $89.

ps

(Long answer why $89 for Amazon: A regular publisher takes something 
like 6 months to publish a book and gives you 10% and take all the 
rights mostly. So I kind of chose POD publishing (print on demand) where

only 1,000 copies get printed at a time. But marketing is limited, so I 
have to register the book with Amazon after they build up stock (vs the 
web site that is pubishing it, that can do it today) which takes time. 
My current estimate is that a week after X-mass will it be on Amazon, 
and because Amazon takes %40 cut... prices is higher. They also will use

a 2nd publisher. That's right, 1 book, 2 publishers. That is even a 
longer story. Once you publish a book you will find all the way's they 
get you. )

You can instantiate a tag from within a tag. You would need to set the

Re: Struts 1.1 book available for order

[Vic Cekvenich]

There is a chapter each on Validator and Tiles. In addition, there is an 
appendix on Validator and Tiles (the appendix is just a reprint of the 
web site's by Cedric and David).

The full TOC is on baseBeans.net / book.

Nothing on Role Based Actions.

I do cover JDBC DB security realms (JAAS), XSLT, SQL/DB, etc.

I guess in a while there will be posts from readers who completed the 
book. Also news.basebeans.com / mvc-programers will have student reviews 
of the people who took the class and read the book as well.

I will announce Amazon. They will cary it for $89.

Vic
ps

(Long answer why $89 for Amazon: A regular publisher takes something 
like 6 months to publish a book and gives you 10% and take all the 
rights mostly. So I kind of chose POD publishing (print on demand) where 
only 1,000 copies get printed at a time. But marketing is limited, so I 
have to register the book with Amazon after they build up stock (vs the 
web site that is pubishing it, that can do it today) which takes time. 
My current estimate is that a week after X-mass will it be on Amazon, 
and because Amazon takes %40 cut... prices is higher. They also will use 
a 2nd publisher. That's right, 1 book, 2 publishers. That is even a 
longer story. Once you publish a book you will find all the way's they 
get you. )

RE: Is there a way to "call" a struts custom tag from your own custom tag?

[Hani Hamandi]

Thanks for your answer David.

Again, maybe I was not clear in my original message, even though I thought I
were.
But I am really not trying to do nesting here. I am simply trying to write a
custom tag:

Normally, when you write a custom tag, the only tags you can use in
out.print(" ... ") are the plain old html tags. I want to be able, from
within my custom tag, say in doStartTag(), to do something like
out.print("") where  is not
simply written back to the browser as is, but actually evalutated on the
server.

Thanks again for your suggestion,
Hani.

Hanikh,

You can instantiate a tag from within a tag. You would need to set the

appropriate tag setters like setParent and setPageContext. It may or 
may not work depending on how the tag was written. I also don't think 
it is an ideal way to nesting tags but it does work when the output of

one tag changes enclosed tags.

After seeing your table of contents I wonder about what is in this book.
Which of the extensions that are not part of the official struts
distribution does the book cover [i.e. Validator by David Winterfeldt, Tiles
by Cedric Dumoulin, Role Based Actions by Nic Hobs, etc.]?

Also, will there be a sample chapter to read on-line before deciding to
purchase the book.  I'd hate to spend $70 an find out I can't read it.

I assume you will announce when Amazon will be carrying it as well.  [It is

RE: File Upload Problem.

[SCHACHTER,MICHAEL (HP-NewJersey,ex2)]

Marli,

Your multipart data seems to be right. Make sure you prefix it with
the normal HTTP headers that go with a multipart request, I think something
like:

Content-Type: multipart/form-data; boundary=...\r\n
--boundary
 -same stuff as you had for the multipart data goes here

If you're still having this problem, would you mind sending me the stuff
that you're using so I could take a look at it?

Hi Jon,

I am trying to do file upload programatically, not using the browser and I
want
to use the struts file upload library to achieve this.

So I want to try the library first by writing a simple html file and a
simple
servlet for testing.
Does this mean that I cannot use the upload code if I don't use struts tags
??

Thanks.
Marli.

  I have search the archive and seen this bounced around, but can't seem to
find a complete working example. I have:

FormBean where one property is an Array of SomeBean;

SomeBean has three properties, two int, one string;

FormBean inits properly with an Array of SomeBean (via another Action);

form.jsp iterates over array of SomeBeans, creates indexed text input boxes.
These display just fine.

When I submit the form, the Action can't get at (or I don't understand how
to access) the SomeBean Array.  If I kick back to the form, the other form
fields keep any changed values, but the SomeBean Array goes null.

  I've been banging my head on this forever, so I would really appreciate
any help!  I've got the nightly build from 11/28/01 running

Thanks,

A servlet would be better than using a plain JSP, because coding &

U can still use Struts by forwarding to a servlet with two request
parameters one for the XML document & the other for the stylesheet, Xalan
can be used to get the resulting output which can be then streamed to the

RE: session id is same for different Browser

[Gao, Gang]

Rob,
I did start two instances of the browser. later I even try logon from IE and
Netscape separately, but I can also get same session ID. I also found
sometimes I get the same session id, sametimes session id is different which
is what I want.
Thanks a lot.

You will see the same session ID for two browser windows if you 'clone' the
browser window with CTRL+N (in IE). To get a separate session ID you need
to start two instances of the browser, not clone the existing window.

Gang,
If you are using the same browser (opening 2 versions of IE, Netscape...),
they could be sharing cookies, and thus the same session.

Is there a way to "call" a struts custom tag from your own custom tag?

[Hani Hamandi]

Hi,

My question is actually simple.
I would like to write my own custom tag that, for example, builds a form
using the struts custom tags.

For example, I would like to write a tag like this one:



Which, for example, does this:








This is just an example, I am not particularly interested in building a
form. The key question is how to get your container to actually execute
another custom tag from within your doStartTag() method for example. If you
do out.print(""), of course this will
simply be sent back to the browser as is (text), without any interpretation
on the server side.

I don't know, maybe this is not doable at all, but thanks in advance for any
suggestions,
Hani.

P.S: The thing is, if this is not doable, then using struts kinda prevents
you from writing your own custom tags (unless you extend the struts stuff).
I wanted to write my own custom tag which reads some data from the database,
does a couple of things, and builds an  with the data. But
that's exactly where I got stuck: at the ! Of course, the
regular  would work just fine, but you do want to use the
 for struts to populate your bean. So I ended up using a <%@
include>, at least for now.

The project I'm working on is organized thusly under a com.foo. package:

entities
forms
servlets

with actions in actions, struts forms in forms, etc. Entities is my business entity

RE: Dynamically Developing HTML forms

[Rajan Gupta]

Reply to Rajeev:
In your dynamic web site u probably will still have fixed type of pages
with a predefined format e.g. Form, Report, Report with Graph etc. for say
a Gold Customer etc, in which case these pages could be treated as
templates. I believe that you would be choosing the appropriate template
in an action depending on the customer type & page type setup the bean
which will populate the web page.

If this is completely off the mark, are u talking about a Personalization
Engine such as my.yahoo.com or engines which are sold by Open Market etc

HELP with accessing indexed, nested properties in Action

[John Kowalik]

  I have search the archive and seen this bounced around, but can't seem to
find a complete working example. I have:

FormBean where one property is an Array of SomeBean;

SomeBean has three properties, two int, one string;

FormBean inits properly with an Array of SomeBean (via another Action);

form.jsp iterates over array of SomeBeans, creates indexed text input boxes.
These display just fine.

When I submit the form, the Action can't get at (or I don't understand how
to access) the SomeBean Array.  If I kick back to the form, the other form
fields keep any changed values, but the SomeBean Array goes null.

  I've been banging my head on this forever, so I would really appreciate
any help!  I've got the nightly build from 11/28/01 running

Thanks,
--John

RE: Dynamically Developing HTML forms

[Matt Raible]

I've thought about doing this, and let me know if I'm on the same track as you.

What I'd like to do is to stream XML from my Action class that builds all the
elements of my form - label, value, and control type (text, textarea, select) -
from my form bean.

Then an XSL stylesheet is applied (value held in bean as well) and walla, the
only thing that is static is the XSL stylesheet.

Is this similar to what you're trying to do?

Iterate Design Question

[John M. Corro]

Consider a situation where you want to display a straght listing of items from a 
database.  Something like where you would display a listing of 1-20 products on page 
1, 21-40 on page 2, etc.  There seem to be two ways this gets implemented.

1. Pull the entire table contents, store them into a container of sorts, refer to the 
container's listing from page to page (instead of hitting the database again.

2. Query the DB for only the contents you need on each request.  So user request page 
1, backend queries the the DB for products 1 - 20, returns it.  If the user requests 
for page 2, the backend does the same process over again for products 21-40 and so on.

My specific situation prevents me from doing the first approach because the result set 
is so large (takes too long to make that initial DB call)  and the listing changes so 
often that it's possible a user may be view an inaccurate listing.

In going forward w/ approach 2, I've been having some issues I'd like to bounce off 
anyone w/ experience in the matter.
- Thought about using the PreparedStatement.setMaxRows() method, but if I do something 
like "SELECT ... FROM Products WHERE...", I don't know if the statement is smart 
enough to optimize itself to only retrieve 20 products.  The docs say that "the excess 
rows are silently dropped", but I don't know if "silently" means it pulls all the 
records and only returns 20.  If that is the case that would seem like I wouldn't get 
any performance gains (the DB still has to go through the process of retrieving all 
the records).  I imagine that what "silently" means would be dictated by the driver.

- I also thought about using database specific SQL statements to cap the size of the 
result set (ie the 'Limit' keyword in MySQL).  This would be my least desired step as 
I don't want to get tied to a specific database.  I'm not aware of any ANSI SQL 
commands that will do this.

Anyone have any thoughts?

RE: Any Struts Reference Apps that implement DAO?

[Rey Francois]

Not about DAO, but about the difference between web.xml and
struts-config.xml: the first one is loaded by the container, reloading is a
feature of the container, while the second one is loaded by Struts
(ActionServlet), reloading it does not involve redeploying anything, you can
just send a request to the Struts application to reload its configuration.

I'd like to implement the DAO pattern in a struts application I'm building -
is anyone using this - if so, would you recommend?

Also, what's the advantages/disadvantages for declaring your database
parameters in struts-config.xml vs. web.xml?

extending StrutsValidator

[Brian K. Buckley]

Hello,

I've attempted to write my own Validator class by extending StrutsValidator.
My class adds my own static validate method.  It doesn't work.  Instead,
when I use it I get a message appearing in the Tomcat console
"Validator::validate() reflection - MyValidator".

What's wrong?  Is this a proper use of the Validator framework?

Shown below is my class and also my corresponding validator entry in my
validate.xml file.

-Brian

public class MyValidator extends StrutsValidator {

public static boolean validateWidget(Object bean,

Re: browser & platform compatibility

[Ted Husted]

We've carefully followed the HTML 4.01 specification, to the annoyance
of some developers who want to use undocumented features ;-)

If there are any compatiblity issues, it would be because the browser is
not compliant. But I've never seen an incompatibility reported. Only
requests to support browser-specific features that are not part of the
spec. The little HTML Struts generates is quite straight-forward.

There is an issue with the way some version of Netscape on the Windows
platform handled focus when set from a JavaScript. See 

http://www.jguru.com/faq/view.jsp?EID=471948

for a workaround for this Netscape bug.

Re: FW: Dynamically Developing HTML forms

[Ted Husted]

The response is passed to the Action, and so you can use any technique
you would use with a conventional servlet. Just return null to the
ActionServlet when you are done.

http://www.jguru.com/forums/view.jsp?EID=565863

I don't believe JSP pages can be generated dynamically. These are
precompiled by another service (e.g. Jasper) in cooperation with the
container.

Hello Tony,

to my knowledge struts-doesn't provide anything. However, the java-api does
!
Using PreparedStatements, placeholders and 'set' functions automatically
does the escaping for you. Your code then looks like this:

PreparedStatement stmt = con.prepareStatement(
"INSERT INTO TABLE(FIELD) VALUES(?)" ) ;

stmt.setString(1, SomeUnquotedString ) ;
stmt.executeUpdate() ;

The nice thing about using this is that escaping is performed by the
database-specific driver and therefore is always appropriate for your
connection.

Hope this helps,
Mark

Re: Logout Action

[Cameron Ingram]

Actually I am using IE tomcat-3.2 and apache 1.3 , I havent tried it
with the others browsers. I am really quite confused as to why this is
happening. 

>>> [EMAIL PROTECTED] 11/30/01 04:28AM >>>
Hi Cameron!

I had exactly the same problem. Do you use Netscape or Mozilla? Tomcat
JDBC Realm? Well it worked with Konqueror and IE, but not with Netscape
and Mozilla. What I found out was that you have to change the default
preferences settings of the cache attributes within the browsers. Change
them to the upper radio button (I think it was "every session"). Then
all things work fine.

RE: Dynamically Developing HTML forms

[Scott Walter]

Hi,

I have created a dynamic html form using struts. 
Bascially I have a user preference page and want to
dynamically show text input fields based on preference
names (i.e. favorite color, age, etc.) stored inside a
database table.

Since my page would have both dynamic and non dynamic
input fields I integrated the page with struts.  This
is how I accomplished it:

1.  Each dynamic created text field was given a name
that had a prefix of "up_" to indicate it was a
dynamic generated user preference field.

2.  Inside my Form and Action class when the user hit
the submit button on the page I would loop through all
the request parameters looking for paramters that
started with up_.

Any more questions, let me know.

taglibs and jsp:include

[Martin Samm]

this is not directly Struts but seemed the best qualified forum (it is for a 
struts based app however). 
I'm using a custom tag to decide which jsp to include (based on some request 
variables) - the tag then uses a JSP writer to create the  - 
trouble is the ' tag is just written out and not 'interpretted', 
i.e. the page isn't included. How do i get the container to interpret the 
include?

Hi,

It was correctly pointed out to me that I had posted this to the wrong list 
(sorry about that folks!). So, I am posting this here in the hopes that 
some of you can help me:

I have a couple of basic questions (I have only started using STRUTS, so if 
this is obvious please slap some links at me and send me on my way :-) ):

Which object type are people having their Action's send into their business 
and/or data layers: ones that derive from ActionForm or ones that implement 
the Value Object pattern? And how are they converting the business and/or 
data layer's response back (into Action Forms? or are you sending back the 
Value Object so that the custom tags can use that?).

My initial feeling on this was to only send Value Objects to the business 
and data layers so that they would not get coupled to what is obviously a 
presentation layer object (I saw Actions as bridges between the layers, 
converting between the Action Forms and Value Objects and back again). The 
problem I hit was that I did not want to have to write a bunch of 
conversion code (see below) to create my Value Object (since it is 
immutable and, hence does not have the setValue(object) methods that 
automatic JavaBean conversion utilities need):
 MyValueObject val = new 
MyValueObject(converter.convert(form.getValue(), typeOfConversion));

Where the above code would take the String value from an ActionForm, 
convert it into the type needed, and pass it into the constructor for the 
Value Object. Hit the same problem running back the other way (from Value 
Objects to Action Forms).

OR are people making their value objects mutable and maybe having them 
implement a read-only interface that the business and data layers use when 
interacting with or returning the object?

OR are people passing in the ActionForm to the Value Object so that it can 
extract what it needs (are you fronting it with an interface?)?

OR are people passing in a map of properties and their values to the Value 
Object for it to pick and choose what it wants?

OR something else entirely...?

When you are going back from Value Object to Action Form, how are you 
controlling the output format? I know that the Action needs to understand 
the format of the data that it would expect to receive from a submitted 
form... So, I am assuming that all formatting has to happen before it gets 
to the custom tag (the only exception being when it is writing data that 
will not come back through a form or query string). Is this what people are 
doing?

Thanks!

servlet for testing.
Does this mean that I cannot use the upload code if I don't use struts tags
??

Thanks.
Marli.

RE: struts-config not found in Websphere 3.5.2 FixPack3

[Jon.Ridgway]

Hi,

Have you added the ActionServlet mapping into your .webapp
file? This mapping tells the action servlet where to find struts-config.xml.
If you have the mapping what entry do you have for the config parameter?

Change the two lines of code in FormTag.doEndTag that remove attributes from

dbtags ResultSet tag problem

[Maciej Kołodziej]

Hi,

This  code  iterates  ResultSet  inserted  into  session and adds it's
elements to JavaScript table:


   comTresc[licznik++] = "";


And   it   works.   As  You can see ResultSet is inserted into session
with the key "rset".
But I want to use this result set again in this page. If I tried to do
that I got  a  NullPointerException  on doStartTag. So I figured, that
maybe   I   have   to   rewind  this  RS  to  the  beggining  (it's  a
ResultSet.TYPE_SCROLL_INSENSITIVE ResultSet type). So what I do is:

<% ((ResultSet)session.getAttribute("rset")).beforeFirst();%>

And again I get a null pointer exception but this time it's exactly in
this  point  of  generated  servlet  where  the above code fragment is
executed (beforeFirst). It looks like this:

Root cause:
java.lang.NullPointerException
at org.postgresql.jdbc2.ResultSet.beforeFirst(ResultSet.java:762)
at

_0002fkomentarze_0002ejspkomentarze_jsp_0._jspService(_0002fcomments_0002ejspcomments_jsp_0.java:181)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119)
...

My  question  is,  is  it  possible to use same ResultSet twice on one
page? Does this RS tag remove RS object from session?

Maciej

RE: Dynamically Developing HTML forms

[Rajeev Singh]

Hi Tom, 
   By Dynamic generation I mean generation of WEB pages on Fly. If we
generate web pages on fly I don't know how it can be included in the
WAR. In my webapp I am having a fixed set of JSP's plus while
application is running the users will create additional pages which are
reports or new forms  matching to their transactions/profiles.
   Its here that I am not getting how can I use Struts.

Thanx,
Rajeev

No answers as I don't understand the question.
I am really curious a to what you mean by a dynamically generated

Do you mean using introspection/reflection to build an app on the fly?

I have solved this in a former project by writing or own session (bound to

Re: Logout Action

[tw . richter]

Hi Cameron! 

I had exactly the same problem. Do you use Netscape or Mozilla? Tomcat JDBC Realm? 
Well it worked with Konqueror and IE, but not with Netscape and Mozilla. What I found 
out was that you have to change the default preferences settings of the cache 
attributes within the browsers. Change them to the upper radio button (I think it was 
“every session“). 
Sinc then all things work fine.

Re: How to get ActionForm as input

[tw . richter]

Hi Abhishek!

I think there are some suggestions in the mailing list concering multiple submit 
buttons (try 'multiple submit'). But why don't you design a selection list in the form 
for the CRUD-Operations? There you only have to request the concerning selection 
property value and you can decide where to forward. I have done so in my CRUD-Forms it 
works very fine.

How to get ActionForm as input

[Abhishek Srivastava]

Hello All,

I have a  this form can be used to create, read, update and
delete a record from a ejb service.

Since one form can have only one  button, I have created all
four of these operations as hyperlinks.

Now when I click on these links My Action does get executed, but nothing of
ActionForm is populated. The reason I guess is that I have not done a
Form-submit

How can I have the ActionForm populated? I tried giving the input attribute
to the actionmapping in struts.config but that did not help.

AW: Hidden Field in a form. Do I use struts taglib or vanilla html?

["Moritz Björn-Hendrik, HH"]

Ted,

a great idea, but you need to know the name of the actionForm in the
jsp-Page. If you change the name in the struts-config.xml, you have to
change it here, too. Doesn't this hurt struts design principles? Isn't it
better (at least until struts 1.1 is released) to have two methods on the
actionForm-class, one for the values and one for the values, which
internally (i.e. in java-Code) map to a method named getNames?

Re: Hidden Field in a form. Do I use struts taglib or vanilla html?

[Greg Callaghan]

Ted,

Again this is great information. I think it confirms something I have been 
struggling with -:

I am trying to handle the CANCEL case of an "edit a record" screen which was 
arrived at from the previous "list of records" screen.  They use the same 
formbean which has an "action" field.  When entering the first "list of 
records" screen it is set to "action=display", and when entering the "edit a 
record" screen it is set to edit/add/delete as approrpriate.  The reason for 
this is my formbean validation differs in the two cases (another story).

The problem I have is if the use hits CANCEL on the "edit a record" screen I 
wanted to send them back to the "display list of records" screen via the 
associated action (cf directly to the JSP), ie so that the action sets up 
appropriate objects required (don't want to recode this).

The catch seems to be I need to set the "action" request parameter back to 
DISPLAY from say EDIT in the "edit a record" action prior to forwarding to 
the "display list of records" action.

It seems this may not be possible??

- setting action element in the form from within the action prior to the 
forward doesn't work as the pseudo code below indicates that "If a form bean 
is in play, the ActionServlet resets and populates
it from the HTTP request"

- I still haven't found a way to override a request parameters value from an 
action yet??? (it seems possible using a JSP tag, ie the forward tag, so 
maybe I just haven't worked it out yet)

Other this this maybe I need to re-think the design?  :-)

Ideas anyone?

Cheers
Greg

Subject: Re: Hidden Field in a form.  Do I use struts taglib or vanilla 
html?
Date: Thu, 29 Nov 2001 14:16:11 -0500

The general order of things is

1) Client requests an Action URI (the path from the ActionMapping)
2) The container passes the request to the ActionServlet
3) The ActionServlet looks up the mapping for the path
4) If the mapping specifies a form bean, the ActionServlet sees if there
is one already, or creates one.
4.1) If a form bean is in play, the ActionServlet resets and populates
it from the HTTP request
4.2) If the mapping has validate set to true, it calls validate on the
form bean. If it fails, it forwards to the path specified by the input
property, and this control flow ends
5) If the mapping specifies an Action type, it is instantiated if
needed, or reused if already there
5.1) The Action's perform method is called, with the instantiated form
bean
5.2) The Action may populate the form bean, call business objects,and do
whatever else is needed
5.3) The Action returns an ActionForward to the ActionServlet

If the ActionForward is to another Action URI, we begin again, else it's
off to a JSP or something.

If the ActionForward is to a JSP
1) Jasper, or the equivalent, renders the page
2) If the Struts html tags see the ActionForm in the request (from 4),
it populate the controls from the ActionForm. Else the html:form tag
creates one, and uses its default values in its tags.

(Can't draw, but I sure can number;-)

If you just need to create a blank form (4), you can use a "continue
Action" to pass control through an Action and then out to the JSP.

 public ActionForward perform(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException {

 return mapping.findForward(request.getParameter("continue"));

 }

So in the mapping you specify the ActionForm for this instance,
validate=false, and a local forward for the JSP input form.
