connection already closed problem

[trupti nigam]

I have below code.
Method a{

Call to method b;
try{
create new connection;
call to method c(string a, Connection con);

}catch(){
}
finally{
close connection object.
}

}

method b{
create connection;
create preparedStatement;
run the sql;
in the finally block close preparedStatement and connection;
}

I am getting connection already closed exception from the method c.
Can someone tell me what am I doing wrong?

Thanks,
Trupti

trupti,

your description is quite mixed, or i am not able to get it properly.

your method A calls B (in method B you are creating a connection)
after processing of B again you are creating a connection and sharing it with methdo C.


now question is why are you not sharing connection with B ???

create connection before calling method B and pass the connection in method B.

Then pass same connection to method C

and in finally block of A close one connection.

I can only guess that probably you are processing some resultset or anything else which is dependant of connection created in method B.

pasting actual code here will help

It's quite possible that method c() throws an exception and close the connection which may cause by many problems including db server is down or network has been dropped. You may need to handle this type of exception in mehod b().
