Here is how I understand the BeanUtil.copyProperies. 1. It expects that the src and dest beans have the same member names to be copied. (In your case the customer bean would have id,name,country and select) members.
2. It expects these members to have getter and setter methods. 3. The data type is converted based on rules defined in the commons-beanutils package, so they do not have to be the same data type in most cases as long as there is an applicable conversion rule. I don't believe it will copy a bean (in your case the DynaValidatorForm) into a Collection. You will need to copy from form to business tier bean then add that bean to your Collection (in your case copy the form to a Customer object then add the object to your Collection). Hope this helps, Gary -----Original Message----- From: Heligon Sandra [mailto:[EMAIL PROTECTED] Sent: Thursday, February 27, 2003 8:43 AM To: '[EMAIL PROTECTED]' Subject: Search example of BeanUtilities.copyProperties with a form that display table Importance: High I have a JSP that contains a table of customers for example. Through the business Tier I have retrieved an object Customers that is a Collection of Customer object. I have defined a DynValidatorForm: <form-bean name="customersForm" dynamic="true" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="id" type="java.lang.String[]"/> <form-property name="name" type="java.lang.String[]"/> <form-property name="country" type="java.lang.String[]"/> <form-property name="select" type="java.lang.String[]"/> </form-bean> To populate the form from the business data can I do directly: BeanUtilities.copyProperties(customersForm, Customers); To populate the business data from the form can I do directly: BeanUtilities.copyProperties(Customers, customersForm); These two lines imply that the form and the business data have exactly the same properties, isn't it ? The information about the last column (select or not) is saved in the HttpSession how must I do to update this property ? Is it possible that a form is the combination of multiple Business data collections ? how to make in this case ? Must one define two different forms ? and use the two forms in the same JSP ? I found only one example that uses BeanUtilities.copyProperties (http://drdb.fsa.ulaval.ca/sujets/struts/membership03/index.html) but this example doesn't display any collection only one record. If someone has an other example I am very very interested.
