Question

Friends, tell me please:
What method we should use instead method: compareTo(Date) in order to compare two Dates?
Hint says me: Method 'compareTo(oracle.jbo.domain.Date) not found in oracle.jbo.domain.Date.

Vladimir,
First, create an exception class like this:
package oracle.jhsdemo.model.exception;
import oracle.jbo.JboException;
import oracle.jhsdemo.ResourceBundle;
* JHeadstartDemo-specific exception class that extends JboException.
* This class should be used to throw model exceptions.
* The class calls super in each constructor with JhsUserMessages
* as resource bundle class.
public class JhdJboException extends JboException
     // Constructors
     public JhdJboException(java.lang.String errorCode, java.lang.Object[] params)
super(ResourceBundle.class, errorCode, params);
     public JhdJboException(java.lang.String errorCode)
super(ResourceBundle.class,errorCode, null);
* Get the translated message and strip off product and error code.
* We do this because the errorCode (which includes JHD-) is included
* in the message text. We include it in the message text so it will
* be displayed as well, when not throwing a JhsJboException, but
* directly creating a Struts ActionError or ActionMesage in the web tier.
* @return translated message
public String getMessage()
String message = super.getMessage();
// strip off product code and error code
int pos = message.indexOf(":");
if (pos>0)
message = message.substring(pos+1);
return message;
Change the reference to oracle.jhsdemo.ResourceBundle to refer to your own resource bundle.
Now, instead of a call to JhsdemoUtils.displayJhsdemoUserError you can use:
throw new JhdJboException("JHD-00014");
