Operating System: other
This is a GUI client / application server / database server application.
On the GUI client side, we see java.lang.ClassNotFoundException:
This happens when the database server is down, DBCP cannot connect to the
database, and throws a org.apache.commons.dbcp.SQLNestedException.
Our application server code sends the java.sql.SQLException it sees to the
client via RMI.
However, on the client, we have not provided commons-dbcp.jar.
And I don't think we should - DBCP is server code.
But, when the client does not have SQLNestedException's class file, the attempt
to de-serialize it results in the ClassNotFoundException we've been seeing.
Even old http://java.sun.com/j2se/1.3/docs/api/java/sql/SQLException.html has
the facilities that SQLNestedExcepion offers: It is able to chain another
SQLException to itself. So while SQLNestedException clearly causes problems, I
don't understand what DBCP gains from it.
What would we loose if it were scratched?
