Got it myself now:
I have to add the DynaActionForm-class for the bean - I should have
gotten this earlier... ;)
<form-bean name="wauswahl"
type="org.apache.struts.action.DynaActionForm">
<form-property name="wid" type="java.lang.String"/>
</form-bean>

Whoever you are - could you please point me to the chapter where I find
help in understanding DynaActionForms? And are there any error-codes
explained?
Thx, Fabian

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,
Sudhir

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

Note that dynamic="true" is no longer required in 1.1-b2. It was a hack
to get around some developer laziness at the time this code was initially
created :-).

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"'.
