Do you mean i have to specify the attribute name="aBean"instead of
property="aBean" ?
You only need to specify the 'name' attribute if you want to specify a
bean other than the form bean. Assuming the data you want to reference
is in the form bean, as in your case, you only need to specify the
'property' attribute.
second u forgot the dot in myBeanCode , it's myBean.code , Struts will
do myBean.getCode().
myBeanCode is only a name for the current bean in the select tag
The 'property' attribute on the select tag should name a property in
your form bean. That tells Struts where to store/retrieve the associated
value (current selection).
third : your form property "aBean" is an array & u use a select ( which
a single property)
Do you mean i have to specify the attribute name="aBean"instead of
property="aBean" ?
You need *two* properties on your form bean: one to hold the list of
options, which you have (the 'aBean' property); and one to hold the
value that's actually selected. The html:select tag's 'property'
attribute should reference the second one:
public class MyForm extends ActionForm {
private myBean[] arrayOfMyBean;
private String selectedValue;
public myBean[] getABean() {return arrayOfMyBean;}
public String getSelectedValue() {return selectedValue;}
public String setSelectedValue(String val) {
selectedValue = val;}
}
<html:select property="selectedValue" >
<html:optionsCollection property="aBean"
value="code" label="descr"/>
</html:select>

Thanks for your attention

Please excuse me but i try again ... (hope will never die)
Hi all, i've the following problem using the tag
<html:optionsCollection, the jsp give the following error:
org.apache.jasper.JasperException: No bean specified
Let's say this is my code (actionForm, jsp, bean class)
public class MyForm extends ActionForm {
private myBean[] arrayOfMyBean;
public void reset(ActionMapping mapping, HttpServletRequest
request){
arrayOfMyBean=someClass.getMyBeanArray();
request.setAttribute("aBean", arrayOfMyBean);
super.reset( mapping, request);
}
public myBean[] getABean(return arrayOfMyBean); // i forgot
this on my previous post, not on my code!
}

<html:optionsCollection property="aBean" value="code"
label="descr"/>
</html:select>
</html:form>
</body>
</html:html>

myBean Class:
public class myBean implements java.io.Serializable{
private Integer code;
private String descr;
public Integer getCode(){return code;}
public String getDescr(){return descr;}

public void setDescr(String val){ descr=val;} }
