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

html?

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.

AW: Hidden Field in a form. Do I use struts taglib or vanilla html?
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? Björn-H. Moritz -Ursprüngliche Nachricht- Von: Ted Husted [SMTP:[EMAIL PROTECTED]] Gesendet am: Donnerstag, 29. November 2001 22:19 An: Struts Users Mailing List Betreff: Re: Hidden Field in a form. Do I use struts taglib or vanilla html? The cleanest thing is to put the ArrayList on the ActionForm. The syntax of the options tag is suboptimal, so you need to expose the property as a bean. html:select property=namesId bean:define id=names name=actionForm property=names type=java.util.Collection/ html:options collection=names property=value labelProperty=label/ /html:select So, you go through an Action, and have it setup the names list. If there's validation involved, use the same Action as the input path, so the list gets made again. This also makes it much easier to retrieve the list from a database or static class that is on the business tier. David Lauta wrote: Wow, Thanks Ted this is great info. I have narrowed my problem down to: I want to use a SELECT Tag on a form and I want the options to be populated when the form is first displayed. To do this I need to set an ArrayList of valueLabel pairs in the page Context pageContext.setAttribute(names, actionForm.getNames()); // getNames returns an ArrayList // each Item in the arrayList has a getValue() and getLabel() accessor. This works but is coded in the JSP ( tightly coupling the UI with the Model ). I'm looking for a way to set the attribute outside of the JSP so that the following will work form:select property=namesId onchange=javascript:submitForm() form:options collection=names property=value labelProperty=label / /form:select In the sequence of events listed below when is the earliest that I can obtain the pageContext to call the setAttribute() method on it. I'm guessing that the PageContext of the JSP is the same as the ServletContext of the HTTPServlet Could my problem be related to I am using the ActionForm instead of the ActionFormBean class? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
How to get ActionForm as input
Hello All, I have a html:form this form can be used to create, read, update and delete a record from a ejb service. Since one form can have only one html:submit / 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. Is it possible that I can have multiple html:submit buttons each pointing to a different action. that way also I can solve my problem. Else there should be some way to populate the Form even when a form.submit was not done. Please help. regards, Abhishek. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: How to get ActionForm as input
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.

Re: Logout Action
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.

I have a link that I map to a logout.do action. In this action it basically cleans up the resources and so forth. It clears the objects that I loaded in to the session. It then invalidates the session and then sends the user to a new page. So here is the problem. The first time the user goes through the application every thing works as it should. Then if the user goes back to the login page(with out closing the browser) and goes through the app again. Then clicks on the logout link the user is forwarded to the logout page but the log out action does not seemed to be called. I checked the session objects in login section and they are definitely present when they shouldn't be. By the way this does not happen if the user kills the browser and then re-opens.

dbtags ResultSet tag problem
Hi,
This code iterates ResultSet inserted into session and adds it's
elements to JavaScript table:
sql:resultSet id="rs" name="rset" scope="session"
comTresc[licznik++] = "sql:getColumn colName="comment"/";
/sql:resultSet
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?

Best regards,
Maciej

In Struts 1.0.1, init() is called if the ActionForm is instantiated by
the JavaServer Page. In Struts 1.0, this only happens when the
ActionForm is instantiated by the ActionServlet. Of course, any default
values assigned to the fields in the ActionForm class itself will be
available in either case. The recommended control flow is to go through
an Action first, and populate the ActionForm there. Populating the
ActionForm from the JSP is a Model 1 strategy.

The reason I'd do it that way is that I imagine the message is a
business
class, and you don't really want you model polluted by extending an
ActionForm. Maybe I've been living in OOAD land too long though ;)
This can trip you up though - at least once I have added the form
element,
added it to the bean, added it to the form bean, and forgetten to do
the
setter in the action :) The way around that is probably a function in
the
form bean that says fill my business class and fill from a business
class. Actually, I might put that in my todo list :D

The data I am storing in the bean is logically different from what the
hidden field value is, I have a message
message
{
string Recipent
string From
string MessageBode
}
And the hidden field is action=sendMessage and I didn't think that
message
{
string Action
string Recipent
string From
string MessageBode
}
would be the correct thing to do, but I am open to suggestions. If it
works out easier to put this extra field in my message formbean then I
will do it. What do you think?

So I want to try the library first by writing a simple html file and a

Does this mean that I cannot use the upload code if I don't use struts tags

Subject: File Upload Problem.
Hello,
I was writing some upload code to test the use of MultipartIterator class.
My html code is as follows:
-
BODY BGCOLOR=FF
h1 MULTIPART TEST/h1
FORM NAME=loadfile
ACTION=/MDC/servlet/servlet/com.cisco.nm.callhome.servlet.TestServlet
ENCTYPE='multipart/form-data' METHOD=POST
CLASS: INPUT NAME=class TYPE=text VALUE=File
br
COMMAND: INPUT NAME=cmd TYPE=text VALUE=Add
br
DATA (XML): textarea name=dataParam rows=20 cols=80/textarea
br
File Location: INPUT TYPE=file NAME=uploadfile SIZE=50
br
INPUT TYPE=SUBMIT NAME=SUBMIT
/FORM
/BODY
/HTML
My servlet code is as follows:
---
protected void doPost(HttpServletRequest req, HttpServletResponse
resp)
throws ServletException, java.io.IOException
{
LogUtil.debug(_Class, - DO POST);
MultipartIterator iter = new MultipartIterator(req, 64*1024,
Integer.MAX_VALUE, C:/Temp);
MultipartElement elem = null;
while( (elem = iter.getNextElement()) != null )
{
if( elem.isFile() )
{
System.out.println(ELEM is a file);
System.out.println(FILENAME = +
elem.getFileName());
System.out.println(FILE PATH = +
elem.getFile().getAbsolutePath());
}
else {
System.out.print(NAME = ' + elem.getName() + ');
System.out.println(. VALUE = ' + elem.getValue() +
');
//System.out.println(elem.getName() + = +
elem.getValue());
}
}
}
When I use my browser to the html file, put some data in the dataParam
text area and
hit Submit, I got the following result in Tomcat stdout.log
NAME = 'class'. VALUE = 'File'
NAME = 'cmd'. VALUE = 'Add'
/File'/AuthTupleswordbejo/Password1663eb7d56063ec67f23be/Checksum
ELEM is a file
FILENAME = ch-p506-2_enable_callhome.cfg
FILE PATH = C:\Temp\strts4674.tmp
NAME = 'SUBMIT'. VALUE = 'Submit Query'
My question is:
--
* Is there an explanation on why the dataParam parameter is not printed
out,
or printed out but has the wrong value ?
* I also have written a Java multipart writer to test it, but it looks like
that the file is always
larger by 2 bytes. Isn't the format for multipart request like this:
--Boundary\r\n
content-disposition: form-data; name=blah; filename=file.txt\r\n
Content-type: application/octet-stream\r\n
\r\n
Body goes here..
--Boundary--\r\n
Am I correct about the CRLF (\r\n) ? I have read RFC 1867 and RFC 2046
and it looks correct.
Any ideas ?
Thanks in advance.

[REPOST FROM DEV] General Model Question...
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).

RE: [REPOST FROM DEV] General Model Question...
Hi Allen, Have a look at: http://www.mail-archive.com/struts-user@jakarta.apache.org/ Ted Husted posted a response to similar question(s) yesterday. Jon. -Original Message- From: Allen M. Servedio [mailto:[EMAIL PROTECTED]] Sent: 30 November 2001 13:01 To: [EMAIL PROTECTED] Subject: [REPOST FROM DEV] General Model Question... 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!

taglibs and jsp:include
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 jsp:include - trouble is the 'jsp:include tag is just written out and not 'interpretted', i.e. the page isn't included.

RE: Dynamically Developing HTML forms
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_.

Cheers Tony 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.

Re: browser platform compatibility
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.

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?

RE: Dynamically Developing HTML forms
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.

Is there a way to call a struts custom tag from your own custom tag?
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: myTabLib:mytag / Which, for example, does this: html:form action = myAction.do bean:message key = myLabel / html:text property = myField / /html:form 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(bean:message key = \myLabel\ /), 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 html:select with the data. But that's exactly where I got stuck: at the html:select! Of course, the regular select would work just fine, but you do want to use the html:select for struts to populate your bean. So I ended up using a %@ include, at least for now. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Your multipart data seems to be right. Make sure you prefix it with

Hello,
I was writing some upload code to test the use of MultipartIterator class.
My html code is as follows:
-
BODY BGCOLOR=FF
h1 MULTIPART TEST/h1
FORM NAME=loadfile
ACTION=/MDC/servlet/servlet/com.cisco.nm.callhome.servlet.TestServlet
ENCTYPE='multipart/form-data' METHOD=POST
CLASS: INPUT NAME=class TYPE=text VALUE=File

COMMAND: INPUT NAME=cmd TYPE=text VALUE=Add
br
DATA (XML): textarea name=dataParam rows=20 cols=80/textarea
br
File Location: INPUT TYPE=file NAME=uploadfile SIZE=50
br
INPUT TYPE=SUBMIT NAME=SUBMIT
/FORM
/BODY
/HTML
My servlet code is as follows:
---
protected void doPost(HttpServletRequest req, HttpServletResponse
resp)
throws ServletException, java.io.IOException
{
LogUtil.debug(_Class, - DO POST);
MultipartIterator iter = new MultipartIterator(req, 64*1024,
Integer.MAX_VALUE, C:/Temp);
MultipartElement elem = null;
while( (elem = iter.getNextElement()) != null )
{
if( elem.isFile() )
{
System.out.println(ELEM is a file);
System.out.println(FILENAME = +
elem.getFileName());
System.out.println(FILE PATH = +
elem.getFile().getAbsolutePath());
}
else {
System.out.print(NAME = ' + elem.getName() + ');
System.out.println(. VALUE = ' + elem.getValue() +
');
//System.out.println(elem.getName() + = +
elem.getValue());
}
}
}
When I use my browser to the html file, put some data in the dataParam
text area and
hit Submit, I got the following result in Tomcat stdout.log
NAME = 'class'. VALUE = 'File'
NAME = 'cmd'. VALUE = 'Add'
/File'/AuthTupleswordbejo/Password1663eb7d56063ec67f23be/Checksum
ELEM is a file
FILENAME = ch-p506-2_enable_callhome.cfg
FILE PATH = C:\Temp\strts4674.tmp
NAME = 'SUBMIT'. VALUE = 'Submit Query'
My question is:
--
* Is there an explanation on why the dataParam parameter is not printed
out,
or printed out but has the wrong value ?
* I also have written a Java multipart writer to test it, but it looks like
that the file is always
larger by 2 bytes. Isn't the format for multipart request like this:
--Boundary\r\n
content-disposition: form-data; name=blah; filename=file.txt\r\n
Content-type: application/octet-stream\r\n
\r\n
Body goes here..
--Boundary--\r\n
Am I correct about the CRLF (\r\n) ? I have read RFC 1867 and RFC 2046
and it looks correct.
Any ideas ?
Thanks in advance.

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

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

Passing information to the jsp
If you want to pass data to a jsp, where the information will not be in an HTML form, do I need to pass it through the ActionForm that is in the mapping, or should I just put a bean in the request and use it on the jsp? Dave
My first Struts question
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:
html:select property=opponentName
html:options collection=opponents
property=username
labelProperty=username/
/html:select
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?
(Or am I completely bonkers thinking that the options tag is supposed to
look for the array in various places? Perhaps I need to change
html:options collection=opponents... to something like html:options
collection=form.opponents...
It just occurred to me to look in the bug database at jakarta.apache.org...
I think I might be describing Bugzilla Bug 905 2096...
If so, how can I, on the JSP, get to the ActionForm object so that I can do
a setAttribute?

Corro [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, November 30, 2001 8:43 AM 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? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Is there a way to call a struts custom tag from your own custom tag?
I think the shourt answer is, No. However, what David is saying should get
the job done. For instance I wanted a tag that would allow you to say
mytags:validatedText property=name /
and would output
html:text property=name /html:errors property=name /
so I wrote a tag that extends the Struts Text tag and has an Errors tag.
Here is the source:
public class InputTextTag extends TextTag
{
public int doStartTag()
throws JspException
{
super.doStartTag();
ErrorsTag errorsTag = new ErrorsTag();
errorsTag.setPageContext(pageContext);
errorsTag.setProperty(property);
return errorsTag.doStartTag();
}
}
So the line that says super.doStartTag() will end up doing what html:text
property=name/ would do and the errorsTag.doStartTag() will do the the
html:errors property=name /
Hope this helps.

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

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

I wanted to write my own custom tag which reads some data from the

does a couple of things, and builds an html:select with the data.
But
that's exactly where I got stuck: at the html:select! Of course,
the
regular select would work just fine, but you do want to use the
html:select for struts to populate your bean. So I ended up using a

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

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

I think the shourt answer is, No. However, what David is saying should get
the job done. For instance I wanted a tag that would allow you to say
mytags:validatedText property=name /
and would output
html:text property=name /html:errors property=name /
so I wrote a tag that extends the Struts Text tag and has an Errors tag.
Here is the source:
public class InputTextTag extends TextTag
{
public int doStartTag()
throws JspException
{
super.doStartTag();
ErrorsTag errorsTag = new ErrorsTag();
errorsTag.setPageContext(pageContext);
errorsTag.setProperty(property);
return errorsTag.doStartTag();
}
}
So the line that says super.doStartTag() will end up doing what html:text
property=name/ would do and the errorsTag.doStartTag() will do the the
html:errors property=name /
Hope this helps.

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(html:someStrutsTag /) where html:someStrutsTag / is not
simply written back to the browser as is, but actually evalutated on the
server.
Thanks again for your suggestion,

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.

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:
myTabLib:mytag /
Which, for example, does this:
html:form action = myAction.do
bean:message key = myLabel /
html:text property = myField /
/html:form
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(bean:message key = \myLabel\ /), 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 html:select with the data.
But
that's exactly where I got stuck: at the html:select! Of course,
the
regular select would work just

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.

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.

Missing message for key index.title - Problem Found
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 tomcat/common/lib also
seems to have problems with derived classes
in the /WEB-INF/classes classes.
