sorta bean.
Here is what I did to fix the problem...
* * public Date getReceivedDate()
{
return receivedDate;
}
public void setReceivedDate(Date val)
{
receivedDate = val;
}
public void setReceivedDate*String*(String val)
{
...*
*
Many thanks

Martin, Thanks for your quick reply.
Actaully, the getters both return Date but your comment did make me do a double take and I did notice the setters in this case are overloaded with String and Date. I'll check this out and report back. I'll also confirm with Introspection rather than Reflection as Robert has recommended...

I believe the problem stems from the fact that you have two getters for each
of the properties that are failing - one that returns a Date and one that
returns a String. JavaBeans introspection does not allow that, and so
BeanUtils is (correctly) determining that expiresDate and receivedDate are
not valid properties.

Subject: [beanutils] Problem with missing attributes
I'm having a strange problem which appears to be related to bean utils or collections. The issue is Struts is reporting it can't find some attributes from some beans being accessed via bean:write tag libs. In researching this, I've discovered that the information about the bean being reported by PropertyUtils is in fact missing some accessors/attributes. I downloaded the latest beanutils and collections today and still no go.
Here is how I verified the problem: In one of our JSP pages, we kept getting a runtime exception about a bean (Certification) not having an attribute called receivedDate. To workaround the problem, I created another accessor called getReceived which simply calls getReceivedDate and all is well...
The problems does not appear to be consistent in that some attributes are picked up and some are not. It even has changed across platforms (same code base running on different platforms has different attributes missing)
Here is a fragment of code I stuck into the JSP to confirm that basic java introspection was working vs what beanutils was reporting... Note I wrapped java.lang.reflect output in parens ( ) and the PropertyUtils.describe output in brackets []. The row object is obtained from an <iterate: tag on the jsp page...
<logic:iterate id="row" name="result" property="certifications" scope="request">
<%out.println("<pre>");
java.lang.reflect.Method[] ms = row.getClass().getDeclaredMethods();
for(int ind = 0;ind<ms.length;ind++){
out.println("("+ms[ind]+")");}
java.util.Map m = org.apache.commons.beanutils.PropertyUtils.describe(row);
for(java.util.Iterator i = m.keySet().iterator();i.hasNext();){
out.println("["+i.next()+"] ");}
out.println("</pre>");
%>
...
Got the following results... note several methods are missing...
(public java.lang.String com.seacor.custom.Certification.toString())
(public java.lang.String com.seacor.custom.Certification.getName())
(public void com.seacor.custom.Certification.setName(java.lang.String))
(public java.lang.String com.seacor.custom.Certification.getNumber())
(public void com.seacor.custom.Certification.setReceivedDate(*java.util.Date*))
(public void com.seacor.custom.Certification.setReceivedDate(*java.lang.String*))
(public void com.seacor.custom.Certification.setExpiresDate(java.util.Date))
(public void com.seacor.custom.Certification.setExpiresDate(java.lang.String))
(public void com.seacor.custom.Certification.setSchool(java.lang.String))
(public void com.seacor.custom.Certification.setNumber(java.lang.String))
(public java.util.Date com.seacor.custom.Certification.getExpiresDate())
(public java.util.Date com.seacor.custom.Certification.getExpires())
*(public java.util.Date com.seacor.custom.Certification.getReceived())
(public java.util.Date com.seacor.custom.Certification.getReceivedDate())*
(public java.lang.String com.seacor.custom.Certification.getSchool())
[expires]
[name]
[school]
[number]
[class]
[received]
As you can see the elements in [] are retrieved from PropertyUtils.describe and are missing expiresDate and receivedDate.
The bean in this case (Certification) is a simple value object with public default constructor, simple accessors, and is serialized...
Any thoughts? I'm hoping it is a simple config problem or something obvious I have overlooked.
Thanks in advance
David
