Connection still exists after close

Question

Hello
My connection to the database don't disconnect. I have a servlet, in the doGet it will connect to the database(FoxPro). Then I execute a select command. Until here all works fine. Then I close the statement and the resultset, afterwards I close the connect like this: con.close()
If I now try to open the database with the foxpro programm it can't open the database exclusive! I think its because the connection from doGet is still there.
If the doPost is executed, it will connect also to the database and execute an Update. Then the servlet fails with a NullPointerException.
This error occures every time if I make a connection to the database, close it afterwards, and then open another connection and try to make a query. It doesn't matter what a query it is.
It is because with the close in the doGet is something wrong.
The con.close() command don't throw an exception.
The code I wrote is OK. Could it be that the connection is closed, but the user is still connected in the database? Is there a close for the user?
Or have you an other idea?
I thank you for your help.

The con.close() command don't throw an exception.
The code I wrote is OK. Could it be that the
connection is closed, but the user is still connected
in the database? Is there a close for the user?Have you closed your resources in the following order.
finally{
irs.close(); //resultset
st.close(); //Statement
con.close(); //Connection.
Lastly try...
con = null; to mark the connection object for garbage collection.
Hope this solves your problem
