Re: [BeanUtils] BeanUtils.populate is not working

[MantissaHotmail]

I think I unnderstood what happened.
Inside bean utils (I don't know why) the timesatamp value become a string.
And Bean util (I don't know why either) can set a string to a timestamp
property, but not to a date property.

This dont solve the problem (or explain it..)...
The problem is that despite that java.sql.Timestamp extends java.util.Date
I cant use the setProperty(<bean>, <property nane>, <timestamp value>)
(my property is of type java.util.Date)
If I call directly the set method, passing a timestamp value, it works.
WHY???

I solved this by creating a new Converter class and registering it with
the
ConvertUtils:
public class TimestampConverter implements Converter
{
   public TimestampConverter()
   {
   }
   /* (non-Javadoc)
    * @see org.apache.commons.beanutils.Converter#convert(java.lang.Class,
java.lang.Object)
    */
   public Object convert(Class type, Object value) throws
ConversionException
   {
       if (value == null)
       {
           throw new ConversionException("No value specified");
       }
       // Support Calendar and Timestamp conversion
       if (value instanceof Timestamp)
       {
           return value;
       }
       else if (value instanceof Date)
       {
           return new Timestamp(((Date)value).getTime());
       }
       else if (value instanceof Calendar)
       {
           return new Timestamp(((Calendar)value).getTime().getTime());
       }
       else
       {
           throw new ConversionException("Type not supported: " +
value.getClass().getName());
       }
   }
}
To register it just use:
ConvertUtils.register(new TimestampConverter(), java.sql.Timestamp.class);

Subject: [BeanUtils] BeanUtils.populate is not working
I'm using the beanUtils in an application.
When I try to populate a bean via "BeanUtil.populate"
I receive an error (the error is in the end of the mail) when
the application tries to set a specific property:
private java.util.Date date;
public void setDate(Date date)
{
    this.date = date;
}
The value I'm rying to set is a java.sql.Timestamp (that
extends java.util.Date). If I change the set method to
receive an Objet instead of a Date the application works (If
I change to timesatamp I still receive the same error).
