Hi, I am having Sybase as my backend. When I am inserting to table with a image column which basically stores a large string and the string to be inserted is of length 0,then it thron this exception, java.sql.SQLException: JZ0C0: Connection is already closed. at com.sybase.jdbc2.jdbc.ErrorMessage.raiseError(ErrorMessage.java:498) at com.sybase.jdbc2.jdbc.SybConnection.checkConnection(SybConnection.jav a:1619) at com.sybase.jdbc2.jdbc.SybStatement.checkDead(SybStatement.java:1717) at com.sybase.jdbc2.jdbc.SybPreparedStatement.setString(SybPreparedState ment.java:249) I run my code on Oracle and MS SQL and it works fine in similar conditions. But for Sybase only I get this exception. So I dont think there is connection being closed by my code anywhere. The Sybase help at this link http://sybooks.sybase.com/onlinebooks/group-jcarc/jcg0500e/jc_ref/@Generic__BookTextView/8757 Gives Description: The application has already called Connection.close() on this connection object; it cannot be used any more. Action: Fix the code so that connection object references are nulled out whenever a connection is closed. Has anybody else faced such a problem and what was done to ensure nothing of this sort happened. Thanks, Chinmay
