Array of Bean and optionsCollection (up)
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!
}
__
The jsp:
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html % html:xhtml
/ html:html locale=true body html:form action=/MyAction
html:select property=myBeanCode
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 setCode(Integer val){ code=val;}
public void setDescr(String val){ descr=val;} }
_
Could anyone help me?
Any help will be greatly appreciated.
Thanks in advance
Marcello

Re: Array of Bean and optionsCollection (up)
At first sight, u miss the name of the collection in
html:optionsCollection property=aBean value=code
label=descr/
second u forgot the dot in myBeanCode , it's myBean.code , Struts will do
myBean.getCode().
third : your form property aBean is an array u use a select ( which a
single property)
not clear but i could have understood wrong .
Good luck

R: Array of Bean and optionsCollection (up)
At first sight, u miss the name of the collection in
html:optionsCollection property=aBean value=code
label=descr/
Do you mean i have to specify the attribute name=aBeaninstead of
property=aBean ?
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
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=aBeaninstead of
property=aBean ?
Thanks for your attention

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=aBeaninstead 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
L.
