SecurityException

Hello everyone,

Do you implement the SecurityException by yourself or do you use SUN�s java.lang.SecurityException ?
Thanks a lot for your answers!

Olena.

Hi Olena,

I used java.lang.SecurityException which seems to conform best to the requirement:

Any unimplemented exceptions in this interface must all be created as member classes of the suncertify.db package.

Hi Olena and Wei-ju,

here is what the JDK API says about SecurityException:

public class SecurityException
extends RuntimeException

Thrown by the security manager to indicate a security violation.

That stays in contrast to a must demand in our assignment:

You must not require the installation of a security manager.

What are our exceptions? In my assignment (B&S) I have these three exceptions in my data layer:

DuplicateKeyException

RecordNotFoundException

SecurityException

Honestly I am not sure either

, but I tend more to implement a SecurityException because of the security manager issue.

Olena, seems that the exam take longer than we expected

Hi Darya and Wei-ju,
Thanks a lot for your comments!

Darya,

Yep, I did not expect that I need more time. With full-time job it�s not so easy to make it faster

This preparation is endless

Hi Olena,

I share your

and

and ... Same feelings on my side.

But at least we are careful

Hi Darya,

it is true that the SecurityException is documented as being thrown from the SecurityManager. This holds true for the J2SE, but noone prevents you from using it in your project. At last, it is simply a public API class and the information that within the J2SE it is thrown in the SecurityManager, does not mean that you need to install a SecurityManager.

The SecurityException's constructors are all public, so they are meant to be used (at least that's how I interpreted it

) and reusing the appropriate platform exceptions is generally considered a good habit.

This was the idea I had in my mind when I had to decide whether to create a custom SecurityException or not.

Hi Wei-ju,

Thanks for your reponse.

Using your own SecurityException leads to a compiler problem as described in B&S: How to difference between my and JDK's SecurityException?

As far as I understand, the use of JDK's SecurityException is now only to satisfy the compiler.

You can create SecurityException.java under suncertify.db and use that in Data.java class instead of java.lang.SecurityException...

anything wrong in doing that...

Hi Ken,

you are right. In the meantime I can't even reproduce my compiler error discussed in the thread mentioned previously by me.

Even with the fact Wei-ju passed SCJD with JDK's SecurityException I prefer my own SecurityException.

Thanks,
Darya
