exception handling

[jacob deiter]

I use Spring 2.0,each business service in application throws several exceptions orderexception,creditdebitoverflowexception,dateou tdatedexception,etc.Each customised exception should extends exception super class

class orderexception extends exception {}
 
class creditdebitoverflowexception extends exception {}
 
class dateoutdatedexception extends exception {}

In service class should be as follow

class a {
 
void  e() throws orderexception{}
 
}
 
class b {
 
void  f() throws creditdebitoverflowexception{}
 
}
 
class c {
 
void  g() throws dateoutdatedexception{}
}

each method service throw several exceptions ,so I like to remove the repetitive code as below

class a {
 
void  e() throws baseexception{}
 
}
 
class b {
 
void  f() throws baseexception{}
 
}
 
class c {
 
void  g() throws baseexception{}
}

in baseexception ,declare all exception orderexception,creditdebitoverflowexception,dateou tdatedexception.PLease suggest how it can be done in spring.
