That's correct Jim, it's a standard part of all my ActionForms. But, it's a generic function, you can insert it into any class and be off to the races. As I said, if you wanted to make it a helper function that you just pass a class too, that also shouldn't be a problem, and that would deal with the situation where you can't alter the beans' source.

Frank,

You're using it from an ActionForm....I have this problem in a class where I am implementing a Tiles Controller, could that be the problem? I had a database connectivity problem in this controller class already and had to resort to JNDI.

I always include the following method in all my ActionForms... I'm sure you can do the same in whatever bean you have, or adapt it to be able to pass the bean to it if you can't modify the bean itself... This will actually show you all fields AND their values, but you can of course hack it as you need to...

import java.lang.reflect.Field;

  public String toString() {

String str = null;
StringBuffer sb = new StringBuffer(1000);
sb.append(this.getClass().getName() + " [" + super.toString() + "] = { ");
try {
Field[] fields = this.getClass().getDeclaredFields();
for (int i = 0; i < fields.length; i++) {
if (sb.length() > 0) { sb.append(", "); }
sb.append(fields[i].getName() + "=" + fields[i].get(this));
}
sb.append(" }");
str = sb.toString().trim();
} catch (Exception e) { }
return str;

  }
