FW: newbie html-el question
I am trying to display a value from a requestAttribute in an html-el:text
... but I can't get it to work. Here is my code:
html-el:text: property=searchType
value=%=request.getAttribute(searchType)%/
I recieve the error:
Attribute searchType has no value
Someone told me I have to do something more like this:
html-el:text property=searchType value=${searchType}/
but where would I define the variable searchType that is accessed there?
I tried defining a local string variable called searchType hoping its
value would be passed in, but no luck. Just hitting a wall on what I'm
hoping is a pretty simple issue. I googled this one for a while with no
luck before coming here. Thanks!,
Jim

That's exactly what you should be doing
but where would I define the variable searchType that is accessed
there?
searchType should be saved as an attribute of (preferably) your request
object. Actually, a local variable should also work, you can define it using
the c:set... JSTL tag.
Actually, you shouldn't need to specify a value here at all. The
html-el:text... tag will get the default value from your form bean.

You wouldn't, you'd set the property of the Form bean and let Struts
handle it.
If you need to pre-populate the form, you do that in the Action by
calling setSearchType() on your Form bean. Then when you forward to the
JSP, Struts will fill in the value.
Can you explain more about your situation? I'm making some assumptions
that may not be correct.
In general there's no need to touch the 'value' attribute of the tags
that render HTML form elements.

RE: newbie html-el question
Hi Wendy,
Thanks for responding! Someone showed me a way to do what I needed to do,
but the way I'm approaching the entire problem may be kludged:
The user can click
Search Attributes | Search Components | Search Templates
I've provided html:link's like these respectively:
doPrepareSearch.do?searchType=attribute |
doPrepareSearch.do?searchType=component |
doPrepareSearch.do?searchType=template
so when they user lands on my form, I want to prepopulate the search type
based on what they chose. If they submit a search with bad data, then I'd
want the SearchForm's (extends ActionForm) validate() method to send the
back to the search form, this time keeping their most recent entries to the
form field -- if they changed search type for example now it would be
different.
I am new to Struts and may not be getting a key concept of it's Best
Practices usage. Does it make sense what I've described? Thanks again!,
Jim

RE: newbie html-el question
From: Bender, James [mailto:[EMAIL PROTECTED] The user can click Search Attributes | Search Components | Search Templates I've provided html:link's like these respectively: doPrepareSearch.do?searchType=attribute | doPrepareSearch.do?searchType=component | doPrepareSearch.do?searchType=template When the user clicks one of those, Struts will populate the form associated with (I assume) PrepareSearchAction. Does the mapping for that have a 'name' attribute? Does that Form have get/setSearchType methods? If you need to remember data, it's often easiest to put the Form bean in session scope. And you can associate one Form to several different Actions if it makes sense for your application. Some people will argue against session scope, so you may want to consult the archives and see if their reasons apply to your situation. so when they user lands on my form, I want to prepopulate the search type based on what they chose. That will just magically happen if you let Struts populate the form from the query string parameter and then use the same Form bean when you display your HTML form using the JSP. Rather than confuse the issue, if you still need help, post your struts-config.xml so we can see what you've got. -- Wendy Smoak Application Systems Analyst, Sr. ASU IA Information Resources Management - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well, I believe that you are not allowed to mix static and dynamic text within a JSP, so something like alert(Error message: bean:write name=msg/); should fail. I read once that enclosing the dynamic text in single quotes whould work (never tried it though). One solution that I do know is: snip % String tempString=Error message: + whateverBean.getWhatever(); % alert(%= tempString %); /snip Its ugly, but it works. Anyone know of a more elegant solution? Note that you need to get to the data contained in the bean you are writing from, possibly with a request.getAtribute(attributeName); Good luck, Andreas -Ursprüngliche Nachricht- Von: Daniel [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 24.

Basic question about ActionForms
Hi all, In my app I am using a DynaActionForm with scope = session. When I am calling the action for the first time, obviously the Form is 'emtpy', so I populate it with all the values.. When I am redirected to the action class again, the actionform Should be in the session (in theory). However, what is in the session looks like an 'empty' actionform as it Was before. Now the question: if my actionform has scope of session, do I have to Put the value in the session explicitly or struts will do it for me? IT LOOKS like all the values are erased all the time, no matter if I have Specified as scope session.. Anyone has any clues of what's going on?

greetings a newbie question
hi, just joined the list, and i have a newbie question about struts design. this is where i am at. i have looked at struts about a year back, and rolled my own version of mvc web architecture, stealing several basic ideas from struts. at the time, it appeared that many features of struts were not apparently applicable to the project, so the overhead of configuring struts didn't seem justifiable. now the need for many of the struts features has become pretty concrete, and so i am in process of incorporating struts rather than re-inventing the wheels (and axels and cupholders, etc). while adapting the code base to use struts, i get the sense that: these are the classes/packages; for many, you can configure/adapt it to your needs via config files; in other aspects, you may want/need to subclass and override some of the classes to fit your needs. for the later category of adaptation (subclassing/overriding), the best way seems to be to look into the source to ascertain the default behavior and to ensure the overriding implementation is proper. to put it simply, struts' interface doesn't seem to be clearly defined. by clearly defined interface, i mean programming/usage could/should be via/against the interface without delving into implementation details. if not, pointer(s) to the authoritative interface defnitions would be much appreciated (i told you i'm a newbie). but if so, is this deliberate? and the reasoning behind? some obvious (generic) arguments i could see are: 1. it's advantageous in order to provide greater flexibility, struts being a development framework 2. struts (and web app requirements) are progressing rapidly, so loose interface may serve the purpose better are there more specific reasons other than these? or perhaps it is simply a documentation issue? thanx for any insight/info, dasa ps: i am sending this to both the user and dev lists, thinking the subject is of interest to both. perhaps you'll correct me. again, a newbie here. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: [OT] Design Question
Hi, In my previous company I had exactly what you are talking about, Access and fields are restricted by country (and we had also different Names for fields depending on the country - not internationalization, just Different name). Solution adopted was to have only ONE database in which you store permissions by country.. When your struts app has to display the data in the page, we look up Database to see which fields you can display Hope this helps Regards Marco PS this of course involves writing a gui tool that writes in the Database the permissions and modifies it. If you are using Hibernate Than that will save you a lot of time (you can reuse the framework For both the GUI tool and the struts app) Good luck! -Original Message- From: Claudio Sanchez [mailto:[EMAIL PROTECTED] Sent: 19 March 2004 00:52 To: [EMAIL PROTECTED] Subject: [OT] Design Question Hi all, This is off-topic, but i hope that somebody helps me.

Re: [OT] Object Design Question
On 12/03/2004 21:26, Avinash Gangadharan [EMAIL PROTECTED] wrote: People, I have a design question. It is regarding the retrieval of parent and child objects in the best possible manner. For eg. Let's say there is a Person object with properties such as ssn, lastName and firstname. It also has a list child objects ( Address ) of addresses and a list of previous employees ( Employee ). The Person, Address and Employee objects are separate tables in the DB linked thru ssn. Now what do you guys think is the most efficient way of retrieving a complete Person. If you're talking about SQL, can't you issue one or two SQL queries (with subselects, inner or outer joins) or write a stored procedure to retrieve all the info? (I am used to work with MySQL so my advanced SQL is a bit rusty) Continuing with simple SQL queries only... You could do this in a 2 step mode: - retrieve all persons who have addresses and employees (1 query per person) - for the remaining people (1-2 queries per person) - get the addresses (select... where person.ssn = address.ssn and id ...) (1 query per person) - get the employees (similar to the previous case) (1 query per person) (anyway you get 3 full table search) If you had to had 2 flags on the Person - hasAddresses and hasEmployees - you could make the queries more simple - fetch for (1-1), (1-0) and (0-0) - but maybe it would be more difficult to maintain. If you are talking about a persistence layer (like OJB - see ojb-user mailing list) some of them have lazy loading: it only loads the Person collection of Addresses only if you use them. This will certainly be simpler... And if you have object cache it could even things up (maybe you could issue a great number SQL queries but if the objects were already in cache then there would be no need for any SQL query). The simplest way is ofcourse issue 3 queries one for person, other for the list of address and the third for previous employees. But this does not scale well with increasing size of the table data. For 100 rows of Person 201 queries are issued. 1 which gets 100 persons, 100 each for there subequent address and previous employees. Similarly for a 1000, 2001 queries. Complex queries may be a solution which relies on filtering the resultset but is there a more simple and intelligent approach. Is there a problem with the inherent design itself or is this a common problem. I don¹t see any problem on the design itself (well maybe... it seems you have the social security number has the primary key... pks are not supposed to have any real meaning - what would happen if all of the social security numbers were to be changed? It would generate a huge number of cascade updates. Do whatever you like maybe I am raising a false issue here).

[OT] Object Design Question
People, I have a design question. It is regarding the retrieval of parent and child objects in the best possible manner. For eg. Let's say there is a Person object with properties such as ssn, lastName and firstname. It also has a list child objects ( Address ) of addresses and a list of previous employees ( Employee ). The Person, Address and Employee objects are separate tables in the DB linked thru ssn. Now what do you guys think is the most efficient way of retrieving a complete Person. The simplest way is ofcourse issue 3 queries one for person, other for the list of address and the third for previous employees. But this does not scale well with increasing size of the table data. For 100 rows of Person 201 queries are issued. 1 which gets 100 persons, 100 each for there subequent address and previous employees. Similarly for a 1000, 2001 queries. Complex queries may be a solution which relies on filtering the resultset but is there a more simple and intelligent approach. Is there a problem with the inherent design itself or is this a common problem.

Ridiculously simple (I hope) question about url patterns
I'm trying to an application in progress to use a /do/* url pattern instead of a *.do. I'm finding some strange behavior I haven't quite isolated, but the least of it is that each successive mouseclick is prepending an extra /do to the uri portion of the url. Is there something I need to put into the controller portion of struts config to get this to work correctly?

RE: [OT] Object Design Question
That's the way I have it now, a view object querying the datastore and forming the business objects. The view issues a query for the parent and then calls the views of the children to give their list of objects for that parent and then constituting the parent completely.

RE: html:select question
Hi Paul, Your question seems very similar to my post last week. I need to set a pre-defined option in html:select using the value= attribute, I thought the following will work: For this you can set the attribute in your form class and when you use html:selectin your jsp, while populating the options in the drop down, struts will automatically select the dafult predetermined option and show it as selected. (See vincent and robert's posts). Let me know if that helps! (I did try the same logic and when i give system.out in my jsp, it is identifying the correct default value-only that I cant see the option selected.let me know if yours works from these hints.

Re: Question about DTDs ...
DOCTYPE syntax uses an optional URI for the DTD, so that a validating XML parser can download an unknown DTD and validate the document. Struts registers local copy of it's configuration DTD to the XML parser (struts, tiles validator). This way they're is no need to have access to the Internet Nico.

Question
Hello All, I have a requirement, where on page we have 3 fields named condition1, condition2, and condition3. These three fields are text fields. No problem in doing that. Now the requirement is that if the user wants to add more conditions they can click on the more conditions link and then we are suppose to show next three conditions.. and this process in not finite it can be any number of conditions. How can i handle that ? Any solution. I heard something like indexed property in ActionForm. Can someone please explain what is the best to do in such scineario. Thanks in advance, Vijay.
RE: Question
If you want to get better answers quicker Id suggest you learn the concept of 'meaningful subjects' for emails. Question is not a meaningful subject line. http://www.catb.org/~esr/faqs/smart-questions.html Ok now on to your Question. Having been kind enough to take the time to read it to see if its something I can help with I have found you are in luck. So here is an answer: For 'complex' stuff like this you could make full use nested beans as demonstrated in this tutorial: http://www.keyboardmonkey.com/next/index.jsp In this case as its just one column of text fields you could also get away with just using a collection property in your actionform, and you could back it with a lazy list from commons collections: http://jakarta.apache.org/commons/collections/api/index.html Your view rendering code could iterate through the collection rendering out fields for each: ie renders the html: input name=condition[3] value=foo/ (I think the nested tags can do the indexing for you if your using JSP? not sure. Dont use jsp myself) Your 'add' button or 'conditions link' or whatever would submit and on the server side you try to get the next three items from the lazylist causing them to be instatntiated by the factory you specify. On return to the view the extra fields are rendered ready for input. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, 4 March 2004 06:03 To: [EMAIL PROTECTED] Subject: Question Hello All, I have a requirement, where on page we have 3 fields named condition1, condition2, and condition3.

Re: Another struts question on bean:write
The resulting html text will wrap inside of the element tags that you have placed it into unless you explicitly tell it not to with something like p nowrapcomments here/p Or with css p style=white-space: nowrap;comments here/p So in other words you should not have to do anything. If you want to keep the text width a certain size you can also inline style with p style=width: 200px;comments here/p HTH -- Tim Coy If I use bean:write to display a bean property comments which happens to be a long line of text.

Yes, call myActionForm.setResults(results) instead of request.setAttribute(results, results). This may seem like a minor point (and it is admittedly a simple example), but maintaining complex pages with a lot of structured data behind them gets difficult when you have to pull a bunch of stuff out of the request with no structure defined between the items you are pulling. Using the ActionForm as the root of your data structure is a simple rule to follow that 'scales up' (with data structure complexity) much better than request-stuffing. -Max - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: FormBeans: A question of Style
Agreed. Consider these scenarios: A single form used with multiple actions (think view/edit/new) A tile that conforms to some interface implemented by multiple forms, that is used on different pages An action that manipulates data and forwards to multiple views (WML vs XML vs HTML, or maybe Table vs Graph) Independence is very important for reusability and maintainability. -Original Message- From: Michael McGrady [mailto:[EMAIL PROTECTED] Sent: Friday, February 27, 2004 4:53 PM To: Struts Users Mailing List Subject: RE: FormBeans: A question of Style This is just wrong.

Xhtml tag usage question
I tried to insert the xhtml tag in my pages, but the only way I found is to insert it in each tile that composes my page.

Re: Xhtml tag usage question
Unfortunately it saves the xhtml 'flag' in page scope so there isn't much
you can do about it.
Background: BaseHandlerTag has an isXhtml() method which calls the
TagUtils.isXhtml() method which checks the xhtml 'flag' in page scope.
I did think a solution would be to override the TagUtils.isXhtml() method to
either always return 'true' or check a flag in request scope (which you
would have to set some way) - but unfortunately the instance variable for
TagUtils is both private and final - so theres no way to extend and
implement your own custom TagUtils version in 'vanilla' struts. If you build
your own version of struts, you could change TagUtils itself, so maybe thats
an option for you - but then every time you take a new struts version you
have to re-implement your change.
Another alternative is to extend the struts tags to create 'xhtml'
versions - all you would have to do is override the isXhtml() method there.
For example
public class XhtmlTextTag extends TextTag
public XhtmlTextTag () {
super();
}
protected boolean isXhtml() {
return true;
}
}
So I think you have a few options:
- put the html:xhtml tag in every jsp
- build your own version of struts and change TagUtils
- extend the struts tags to create xhtml versions
Personally, I would go with html:xhtml for now and try to get struts
changed so that either the scope of the xhtml flag can be customized or
TagUtils can be extended and overriden.

RE: custom validator question
I had a custom validator 'futureDate' for which I needed to pass in a
date and time which were 2 different form fields, to check that the date
was in the future.
I passed 2 different values into a custom parameter using two args and
vars:
form name=form
field property=emailDate depends=required, mask, futureDate
msg name=mask key=errors.invalid/
arg0 key=form.emailDate/
arg1 key=form.emailTime/
var
var-namemask/var-name
var-value${dateMask}/var-value
/var
var
var-nametime/var-name
var-valueemailTime/var-value
/var
/field
/form
In the custom validator I retrieved the two values using:
public static boolean validateDate(Object bean, ValidatorAction va,
Field field, ActionErrors errors, HttpServletRequest request)
{
String value;
if (isString(bean))
{
value = (String) bean;
}
else
{
value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
}
String propertyTime = field.getVarValue(time);
String valueTime = ValidatorUtil.getValueAsString(bean,
propertyTime);
. . . . .
Hope this helps

Subject: Re: Xhtml tag usage question
Unfortunately it saves the xhtml 'flag' in page scope so there isn't
much you can do about it.
Background: BaseHandlerTag has an isXhtml() method which calls the
TagUtils.isXhtml() method which checks the xhtml 'flag' in page scope.
I did think a solution would be to override the TagUtils.isXhtml()
method to either always return 'true' or check a flag in request scope
(which you would have to set some way) - but unfortunately the instance
variable for TagUtils is both private and final - so theres no way to
extend and implement your own custom TagUtils version in 'vanilla'
struts. If you build your own version of struts, you could change
TagUtils itself, so maybe thats an option for you - but then every time
you take a new struts version you have to re-implement your change.
Another alternative is to extend the struts tags to create 'xhtml'
versions - all you would have to do is override the isXhtml() method
there. For example
public class XhtmlTextTag extends TextTag
public XhtmlTextTag () {
super();
}
protected boolean isXhtml() {
return true;
}
}
So I think you have a few options:
- put the html:xhtml tag in every jsp
- build your own version of struts and change TagUtils
- extend the struts tags to create xhtml versions
Personally, I would go with html:xhtml for now and try to get struts
changed so that either the scope of the xhtml flag can be customized or
TagUtils can be extended and overriden.

I tried to insert the xhtml tag in my pages, but the only way I found

sufficient to put it in the template file, or in the page using the

Simple ActionError question
Hi all,
just a newbie question. I have a PlaceOrderAction and I want to display as an
ActionError the items that were out of stock.
I would like to be able to pass a String to my ActionError. Is there a way to do this
may using Format? Could somebody provide an example?
Suppose I have a string outOfStock = ULLItitle1/LI/UL
I want to have an effect equivelant to
new ActionError(outofstock));
new ActionError(outOfStock));
if I had new ActionError(error.outofstock));
and in my resources error.outofstock = {0}
How would I pass my string value?
Thank you for your time,
Theo
Re: Simple ActionError question
You ActionError constructor takes additional parameters. Here's a sample from some
code that passes two parameters to a message I'm working
on. In my example, if the user tries to insert a group with the same name as one in
the DB, an error is thrown and html:errors is used to
display the errors to the user
In the resources.properties file there is the following entry
errors.unique={0} has already been used as a {1}
There are two parameters I'm passing to the resource. Since there are many places in
the code where I could get a unique constraint
violation, I pass the field name along with the field name value to prompt the user.
The code follows...
try {
dao.insertSomething(groupName)
}
catch(SQLException exc) {
servlet.log([InsertSomething] - WARNING: error inserting +
groupName + msg: + exc.getMessage());
if( exc.getErrorCode() == 1 ) { // constraint violation
ActionErrors errors = new ActionErrors();
ActionError error = new ActionError( errors.unique, groupName,
Group Name );
errors.add( ActionErrors.GLOBAL_ERROR, error );
_request.setAttribute( Globals.ERROR_KEY, errors );
fwd = new ActionForward( _mapping.getInput() );
}
}

collection=%=ShopWorkOrderFormBean.getShopWorkOrder().getPartList()%
type=com.cat.sdl.fdd.dataBean.shopWorkOrder.PartBean/td
tr
td class=formCellbean:write name=parts
property=partNumber/nbsp;/td
td class=formCellbean:write name=parts property='partDescription'
/nbsp;/td
td class=formCell
a
href=app/fdd/shopWorkOrder/UpdatePartRequest.exec?partAction=updatepartInd
ex=%=index%
img src=images/icoEdit.gif/anbsp;
/td
/tr
/logic:iterate
If you can use JSTL, this may work for you, assuming ShopWorkOrderFormBean
named shopWorkOrderForm in some scope:
c:forEach var=item items=${shopWorkOrderForm.shopWorkOrder.partList}
varStatus=status tr td class=formCellc:out
value=${item.partNumber}//td td class=formCellc:out
value=${item.partDescription}//td
td class=formCell
a
href='app/fdd/shopWorkOrder/UpdatePartRequest.exec?partAction=updatepartInd
ex=c:out value=${status.index}/'img
src=images/icoEdit.gif/anbsp;/a
/td
/c:forEach

I changed my code to use indexId and got the following error:
symbol : variable indexId
location: class
jsp_servlet._app._fdd._shopworkorder.__createshopworkorder
out.print(weblogic.utils.StringUtils.valueOf(indexId )); //[
/app/fdd/shopWorkOrder/CreateShopWorkOrder.jsp; Line: 136]
Here's the changed code:
logic:iterate id=parts indexId=index
collection=%=ShopWorkOrderFormBean.getShopWorkOrder().getPartList()%
type=com.cat.sdl.fdd.dataBean.shopWorkOrder.PartBean/td
tr
td class=formCellbean:write name=parts
property=partNumber/nbsp;/td
td class=formCellbean:write name=parts
property='partDescription'
/nbsp;/td
td class=formCell
a
href=app/fdd/shopWorkOrder/UpdatePartRequest.exec?partAction=updatepartInd
ex=%=indexId%
img src=images/icoEdit.gif/anbsp;
/td
/tr
/logic:iterate
Any Idea? What did I do wrong?

add index attribute in your logic iterate and append that index to
your host string.
e.g
logic:iterate id=xyzID name=xyzForm property=xyz
indexId=index
yourhoststring+%=indexId %
/logic:iterate

A question on Struts taglib.
Can someone tell me how to reference the index of each element so I
can pass it as a parameter with the a href path string?
For example I have the following code, I want to print out
'partNumber' and 'partDescription' and a a href' with index of each
element'.
logic:iterate id=parts
collection=%=ShopWorkOrderFormBean.getShopWorkOrder().getPartList()%
type=com.cat.sdl.fdd.dataBean.shopWorkOrder.PartBean/td
tr
td class=formCellbean:write name=parts
property=partNumber/nbsp;/td
td class=formCellbean:write name=parts
property='partDescription'
/nbsp;/td
td class=formCell
a href=app/fdd/shopWorkOrder/UpdatePart.exec?index=How to
reference the index here
img src=images/iconEdit.gif/anbsp;
/td/tr
/logic:iterate
Thanks in advance!

Re: html:text question
The message-resource file is loaded at startup an held in memory as an
instance of org.apache.struts.util.MessageResources. The instance is stored
in the ServletContext. To access it from a JSP, look for the
Globals.MESSAGES_KEY attribute:
%@ page import=org.apache.struts.Globals %
%@ page import=org.apache.struts.util.MessageResources %
%
MessageResources mr =
(MessageResources)pageContext.getServletContext().getAttribute( Globals.MESSAGES_KEY );
String dbServer = mr.getMessage( login.db.server );
%
...
td class=left
html:text property=dbServer value=%= dbServer % size=16/
/td
From a servlet, it's
import org.apache.struts.util.MessageResources;
...
MessageResources mr =
(MessageResources)request.getSession().getServletContext().getAttribute(
Globals.MESSAGES_KEY );
String dbServer = mr.getMessage( login.db.server );

You can't nest tags, but you can use the el version of the Struts html
tags:
html-el:text name=username value=${testForm.testers.testerName}/

I know when I use sysdeo 2.2.1 (2.2 is buggy) with Eclipse 2.1 the working directory will be c:\eclipse (cos thats where my eclipse is), so any code in the webapp that makes the assumption that its working directory is the tomcat bin folder has problems.

Client Side Validation Question
Hi, I have a little problem with validation. I have a form with a field html:text that show the property de a bean in a session scope. If the field is empty at the load of the page the validation works right, but if the property have any value at the load the validation (required) fail. I think that cause is the render of the html:text to: input value=some value and the value is not null. If the form field is cleared in the screen is empty but code fail to validate. Are there a workaround for this? Thanks in advance. -- Juan Carlos Paramá - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
