Beautiful! Thanks. Now why I didn't I think of that:)...( ummm
'cause you're a dumbass:)
Just curious, how big is 'too big' of a collection to store in
request and/or session scope? I love the functionality of this
display tag http://edhill.its.uiowa.edu/display/ but if I happen
to be dealing with huge(?) lists this might not be an option any
more and I'm going to go with the idea you've suggested.
Thanks again.

Got it myself now:
I have to add the DynaActionForm-class for the bean - I should have
gotten this earlier... ;)
<form-bean name="wauswahl"

Whoever you are - could you please point me to the chapter where I find

DynaActionForm - docs somewhere? Bean Creating Exception?
Posted by Fabian Sommer <fa...@web.de>.
Hello!
I try to use DynaActionForms for the first time. I tried to do it the
way explained below, but all I get from Tomcat is this errormessage:
Exception creating bean of class null: {1}
Does anybody know the meaning of this errormessage?
Are there some docs on the use of DynaActionForms somewhere out there?
They seem to miss within actual struts docu...

If you don't need custom reset() or validate() methods, that is correct --
you do not need to create an ActionForm class of your own.
If you do need custom reset() or validate() methods, then you can still
subclass DynaActionForm, but you only have to implement those two methods.

DynaActionForm is an implementation of the DynaBean interface from
commons-beanutils -- see online JavaDocs at
<http://jakarta.apache.org/commons/beanutils/api>. So, if you've declared
your form bean like this:
<form-bean name="logonForm" ...>
<form-property name="username" type="java.lang.String"/>
<form-property name="password" type="java.lang.String"/>
</form-bean>
then, in your LogonAction, you can access the properties like this:
DynaActionForm daf = (DynaActionForm) form; // Save casting every time
String username = (String) daf.get("username");
String password = (String) daf.get("password"));
There are also get() methods for accessing indexed and mapped properties,
as well as set() methods to update all these things.
You can also use PropertyUtils and BeanUtils to access properties in a
DynaBean, because they call the get() and set() methods for you
transparently on a DynaBean.

Error while Retrieving FormFile From Map
Posted by "Sudhir S. Shetty" <ss...@powershare.net>.
Hi,
I have a Jsp page in which I upload a file using the <html:file
property="prtFormFileAttachment"/> tag,
In my action class I use BeanUtils to get a Map of my form Bean in which I
have a FormFile As an attribute.
I pass this Map to my Bussiness Object,
In the Bussiness object when I issue the command
FormFile pvtFormFile = (FormFile)pvtMapForm.get("prtFormFileAttachment");
I get an Exception
java.lang.ClassCastException: java.lang.String
at com.inveniotech.docmgt.DmDocMgtBaseBo.insertAttachedModel(DmDocMgtBaseBo
Kindly guide mne as to how can i get the file from the Map
TIA,
regards,

Re: ActionForm and DynaActionForm

Hi,
So does this mean that if i am using DynaActionForm i dont need to define any action form .i.e. a class which extends ActionForm and has all the get and set methods for input fields???
so in this case how can i access these fields on in my Action class, normally in my ActionClass i will get the values set in the fields from ActionForm class like
testform data = (testform) form;
where testform is the class which extends ActionForm and has get and set method, so in DynaActionForm if i dont have to define ActionForm, how can i get the values in Action class

Re: ActionForm and DynaActionForm
Posted by John Yu <jo...@scioworks.com>.
Use ActionForm if you inherit your own JavaBean-compliant FormBeans.
Use DynaActionForm if you don't want to code the tedious getter/setter
methods but rely on the DynaActionForm's dynamic properties (think
name-value pairs, something like HashMap). (Note: DynaActionForm is
*psuedo* JavaBean-compliant. It behaves as if it's a JavaBean with the
BeanUtils library.)
To use DynaActionForm, you need to specify the <form-property> elements
inside the <form-bean> config element and specify 'dynamic="true"'.

Re: Struts and Large ResultSet

Also... here is an improved with source code open source versoin of
CachedRowSet at:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/src_05d/basicPortal/src/org/sourceforge/
It works great with DAO.
(Everyone should consider hinding how DAO is implemented, weather
RowSet, EJB, JDO or some O/R thing, so that application does not need to
change if the persistance changes. Sometimes, people that use EJB need
to convert to RowSet, etc. or similar.

| Hi,
| I went through all the mails on this topic, but the problem is i
cannot
| say that i want item between 20 and 40 ( i m developing item master)
also
| i cannot get the keys and keel them in session as at some time the
item
| may be deleted from main database and then i will have to check for
the
| conditions when loading data,
| My database is as400 which does not allow row count etc available in
| oracle and sybase, has anyone used apache torque, i guess it helps
| inhandling this type of problems, also i am studying the j2ee pattern.
| And beleive me people for whom i am developing software go through
| millions of records in a day..
