Getting values from ActionForm bean
I'm new to struts and would like to get a handle on a few things. I
made certain to search the archives for an answer to my current problem,
but was unable to find an answer. So I post my question here.
I have an ActionForm in which I added a method that queries a database
and gets a name/id pair and adds them to a hashtable. On creation of
the form(in the JSP associated with the ActionForm class) I want to
populate a combobox on the form with values from the hashtable. Here's
what I tried, and the results of the code:
JSP
<html:select property="customer" size="1">
<html:options property="customers"/ labelName="value"
labelProperty="key">
</html:select>
ActionForm
public Hashtable getCustomers(){
// query database, build hashtable
return hash;
}
The ActionForm is a request scope bean, as specified in struts-config.
Here's the error I get:
javax.servlet.jsp.JspException: Cannot find bean exportForm in scope request
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:486)

Re: Getting values from ActionForm bean

Is this a typo? If not, it is probably your problem.
>> <html:select property="customer" size="1">
>> <html:options property="customers"/ labelName="value"
>> labelProperty="key">
>> </html:select>
Should be:
<html:select property="customer" size="1">
<html:options property="customers" labelName="value" labelProperty="key"/>
</html:select>
Backslash denoting end of element in wrong place.
Besides that, I use the 'collections' attribute of html:options, and don't
use labelName. Example:
<html:select property="typeId">
<html:options collection="typecollection" property="id"
labelProperty="name"/>
</html:select>
In this case, 'typecollection' is a Collection of objects that have getId()
and getName() methods. The return of these methods will be used to populate
the drop-down list. The 'property' attribute of the html:select element
denotes which option to select by default (that is, to add the 'selected'
attribute to). This is determined by calling the method of the form bean
denoted by the 'property' attribute. In other words, when the return of
[form_bean].getTypeId() matches [typecollection].getId(), the option would
be 'selected'.
Use case: in the case that three objects in 'typecollection' had ids of
1,2,3 and names of name1,name2,name3, and the [form_bean].getTypeId()
returns 2, this would be the output:
<select name="typeId"><option value="1">name1</option>
<option value="2" selected>name2</option>
<option value="3">name3</option></select>
Hope this helps,

Re: Getting values from ActionForm bean
Posted by Ted Husted <hu...@apache.org>.
My best advice would be to
1) Link to an action first rather than directly to the JSP
2) Retrieve the options in the Action, and then put the hashtable into
the request
3) Forward the request to the JSP, and pickup from there
ActionForms are simply meant as a container for the input from an HTML
form. It's not a good idea to subclass them with other functionality.
If you post the question from that frame of reference, I'm sure you will
get a better response.

Re: Getting values from ActionForm bean
Posted by Shannon Moschetti <sm...@wideforce.com>.
Included below is info from the jsp, form class, and config file. Any
advice? I'm stuck. I've got a fix, but its really
terrible(embarrassing, but it works).
Here's the relevant JSP code(start.jsp):
<html:form action="/export">
<html:select property="customer" size="1">
<html:options property="customers" labelName="value"
labelProperty="key"/>
</html:select>
<P>
<html:submit property="addButton" value="Export"/>
</html:form>
ExportForm(ActionForm):
public Hashtable getCustomers(){
....
Hashtable hash = new Hashtable();
ResultSet rset = statement.executeQuery("select name, id from table");
while(rset.next()){
hash.put(rset.getString("name"), rset.getString("id"));
}
.....
return hash;
}
struts-config.xml:
<form-beans>
<!-- Export Form -->
<form-bean name="exportForm"
type="com.foo.ui.struts.form.ExportForm"/>
</form-beans>
<global-forwards>
<forward name="export" path="/content/start.jsp"/>
</global-forwards>
<action-mappings>
<!-- Export Action -->
<action path="/export" input="/content/start.jsp"
name="exportForm" scope="request"
type="com.foo.ui.struts.action.ExportAction">
<forward name="manager" path="/content/start.jsp"/>
</action>
</action-mappings>

Re: Getting values from ActionForm bean
Posted by John Raley <jo...@moonlight.com>.
(Sorry if this duplicates a previous response)
The fact that the bean name is null makes me suspicious:
1. Are you using <html:options> within an <html:form> tag?
2. Does your action specify a name (in struts-config.xml)?
Or,
does your form bean class have a customers property?
