Re: logic:iterate tag fails on large dataset, succeeds onsmall one?
If both JSTL and Struts are failing, it's probably your code that's broken. David Often a reasonable assumption, in the circumstances, but it turns out not so. I got my page to work with a straight Servlet full of out.println() statements. Then I got it working using one Servlet filling my bean and putting it in session context and then forwarding to the other, in case that was the problem. And then I put in c:out tags to replace my bean:write tags, which I perhaps should have done in the first place. I guess I assumed they'd be as interchangeable as c:forEach and bean:iterate. But c:out works. Which leads me to conclude that the problem might be in bean:write. Am I correct in thinking that future versions of Struts may end up using JSTL anyway? If so, then I guess I'll keep to this approach. Someone else can debug bean:write if they want to. Aaron V.

The Struts tags are largely in maintainence mode at this point because the emphasis is on using standardized technologies like the JSTL. There's been no decision regarding the future of the Struts tags but I haven't seen many committers interested in adding new ones or upgrading existing tags. There doesn't seem to be much point in maintaining proprietary tags when the standard versions are easier to use and more powerful. I'm glad you got it working!

Re: logic:iterate tag fails on large dataset, succeeds on small one?
Hi,
I am using struts validator in the logon.jsp of my application. If I don't
enter the username click on submit the message displayed is null is
required. Instead it should be Username is required.
The part of the code in the validator-rules.xml is correct. I have given
msg=errors.required
Also I have given errors.required={0} is required.
prompt.username=Username in the ApplicationResources.properties file.
Still it is giving the same alert as null is required instead of
Username is required.
The corresponding part in the validation.xml is
field property=username
depends=required, minlength,maxlength
arg0 key=prompt.username/
arg1 key=${var:minlength} name=minlength
resource=false/
arg2 key=${var:maxlength} name=maxlength
resource=false/
var
var-namemaxlength/var-name
var-value16/var-value
/var

var-nameminlength/var-name
var-value3/var-value
/var
/field
Has anybody experienced this problem earlier ?

Re: logic:iterate tag fails on large dataset, succeeds on smallone?
hi,
this happens only when struts is unable to load the resources from
the bundle. make sure u have everything in place and restart web
application or server.
also u may want to try getting that prompt.username from the bundle
using bean:messagekey="prompt.username"/
in ur jsp to actually check if struts or validator is the
culprit.

I suggest you use the JSTL's c:forEach tag instead of the Struts iterate tag. I have dynamic query pages that use forEach and display n number of fields with no problem. As an added bonus you'll get improved page rendering time because containers can optimize the performance of JSTL tags. David --- Aaron Humphrey [EMAIL PROTECTED] wrote: I am trying to do a very simple data-display web application using Struts, with MySQL on the back end. Basically, I take a ResultSet and its ResultSetMetaData and put it into some beans. I have a TableDataView object which contains a FieldList and a RecordCollection. FieldList has a property called fields which returns a List. RecordCollection implements Collection, and containts an ArrayList of Record objects; Record returns an array of the field value objects as the property fieldValues. My JSP page(showtable.jsp)looks like: html:html TABLE TR logic:iterate id=fields name=tableDataView property=fieldList THbean:write name=fields //TH /logic:iterate /TR logic:iterate id=record name=tableDataView property=recordList TR logic:iterate id=fvalues name=record property=fieldValues TDbean:write name=fvalues //TD /logic:iterate /TR /logic:iterate /TABLE /html:html If I run this on a small table, with 10 fields and 11 records, it works fine. If I run it on a large table, with 28 fields and 307 records, then I get: javax.servlet.ServletException: cannot find bean fvalues in any scope at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageCon textImpl.java:533) at org.apache.jsp.showtable_jsp._jspService(showtable_jsp.java:192) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137) ...[deletia...I can't imagine that any of it has anything to do with my error] at java.lang.Thread.run(Thread.java:536) I can eliminate this problem if I reduce the number of fields in the table to 9 or 10, but I can't see why this should be a problem, and certainly not why my looping bean should suddenly become unavailable. My unit tests seem to be telling me that my Record bean should be properly returning a list of 28 field values. I don't know at what point things are breaking down. I'm not experienced with JSP tag programming, so I haven't been able to learn much from IterateTag.java, or the compiled version of showtable.jsp.

Re: logic:iterate tag revisited
Yep struts cannot simply act as you wanna do. Before you can update your files path or everything else you will need to tell an action : Hey retrieve all the kinds of datas on a whole collection I will made some change on it First you got an view page who juste iterate your collection. and have a tag just as you say to will store some variables in your request. But one trouble I see is you are not in a windows like program, where you can just made some appropriate change and then pass it to whatever you want. If you wanna do your job, before you can send to an appropriate action, you will need to hit it by a client side programming.

RE: logic:iterate tag revisited
Yeah that's col, I figured I would have to do that. that's the way I originally was going to do it, This then leads me to my next question, which was in the p.s. of my previous post, how does struts create a formfile for upload form the path entered by the user. My problem is, there could be any number of image files needing uploading, depending on the strutcture of the template they are going into. Hence, I can't just have a fixed number of FormFile fields in my form. So when the user submits the file details, I want to be able to upload that file to the server, then process it from there. How do I do that. There isn't much info about uploading a dynamic number of files to the serve using struts.

From a very quick look one thing is your ArrayList needs to contain a class
that has get/set methods for it's properties. You've set them like
m.id=123;
m.name=John;
when it should be
m.setId(123); struts will call
the String getId() methoid to get the value to display.
Also in the iterate tag's type=... you must specify the type of the object in
each elemnt of your ArrayList ie/ type=MyClass.

Re: logic:iterate tag
Complementing, you don't need to specify the iterate tag's
type attribute if you are using the bean:write tag
(which uses reflection to get the properties).

class
that has get/set methods for it's properties. You've set them like
m.id=123;
m.name=John;
when it should be
m.setId(123); struts will call
the String getId() methoid to get the value to display.
Also in the iterate tag's type=... you must specify the type of the object
in
each elemnt of your ArrayList ie/ type=MyClass.

Struts is hard
work in the early stages, but you have to go thru it.
From a very quick look one thing is your ArrayList needs to contain a
class
that has get/set methods for it's properties. You've set them like
m.id=123;
m.name=John;
when it should be
m.setId(123); struts will call
the String getId() methoid to get the value to display.
