//from the client I call this class as such:::
DataClient instanceget = null;
try{
instanceget = new DataClientLocal("db.db");
}
.......etc etc

Here is the error:::::
Exception in thread "main" java.lang.VerifyError: (class: suncertify/db/FlyTable
Model, method: <init> signature: ([[Ljava/lang/Object;Lsuncertify/db/DataClientL
ocal

V) Bad type in putfield/putstatic

thanks Lisa in my DataClient that is my Interface which is public and in the same package
I just declare all the Data Class methods and extends Remote
Thanks Lisa

What if you changed the code
//from the client I call this class as such:::
DataClient instanceget = null;
try{
instanceget = new DataClientLocal("db.db");
}
to the following:
//from the client I call this class as such:::
DataClientLocal instanceget = null;
try{
instanceget = new DataClientLocal("db.db");
}
(I am guessing that the error occurred on the assignment of the new DataClientLocal object ref to the DataClient reference.)

thanks Sir I tried same error great guess..
Thanks Lisa

Sorry, I took a guess based on the information at hand.
Is there additional information in the stack trace from the exception? I have a debug mode where lots of printlns are written for such situations.

Thanks Lisa
