PropertyUtils.copyProperties ?

Hi,

If I am using PropertyUtils.copyProperties(user, info) then original bean
info must to have all properties that user bean has? If info has only 3
properties, and user has 18, copy will not work? I need to use this way,
because, for example, logon form needs only 3 properties, but user form (full
user info) has 18 properties. And only user bean has a method (function) to
check if a user is legal.

Thanks in advance.

Maya

Thank you, Craig. You were right. I had removed (and forgot) a hidden property,
because I cannot figure out how to replace "nested tags".

Can somebody help me to replace <html:hidden property="B" value='<bean:message key
="A"/>'/>
Do I need to use <jsp:useBean ...><jsp:getProperty...> and bean class is
org.apache.struts.BEAN ...

Thanks,

Maya

The copyProperties() method will only copy when the property names
match.  It will ignore any unmatching properties in the origin or
destination beans.
