Subject connection problem using ibatis2.3+postgresql8.3+glassfish2 ( An I/O error occured while sending to the backend.; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException)
Date Fri, 11 Sep 2009 03:00:39 GMT

I have developed a web application required database both oracle and
postgresql. my oracle works fine so far, but PostgreSQL got some problems. I
am using Ibatis 2.3 with PostgreSQL 8.3 on glassfish v2. after the Web
Application deployed, initially everything looks ok, but after a short time,
always hit the below problem:

com.sph.newslink.service.UserManager -
org.springframework.dao.DataAccessResourceFailureException: SqlMapClient
operation; SQL [];   
--- The error occurred in com/sph/newslink/dao/ibatis/sqlmap/TOP_SQLMAP.xml.  
--- The error occurred while applying a parameter map.  
--- Check the TOP_SQLMAP.selectInitialSequence-InlineParameterMap.  
--- Check the statement (query failed).  
--- Cause: org.postgresql.util.PSQLException: An I/O error occured while
sending to the backend.; nested exception is

the sql select statement very simple and should have no problem, I think it
s due to lose of the connection to database,

Is there any way with IBatis to handle this situation be auto-reconnecting
to the database?
