Hi everyone,
I'm new to OJB and I'm trying to use mapping associations. According to the tutorial
you can use Collection, List, and Vector to implement them but when I use something
different from java.util.Vector it fails.
If my "1 side bean" looks like:
private Vector XXX;
public Vector getXXX() {return XXX;}
public void setXXX(Vector XXX) {this.XXX = XXX}
everything works, but when using java.util.Collection instead of java.util.Vector a
NotSuchMethodException:Vector getXXX() is thrown. What am I doing work?
I've got another problem:
I want to use proxies for collections so I wrote proxy="true" in the
collection-descriptor XML element. Using Vectors to keep mappings (the only thing that
works for me) I get:
javax.servlet.ServletException: Error setting field:comarcas in
object:cap.webcap.beans.Provincia
