Subject Connection pooling reconnect problem
Date Wed, 05 Sep 2007 06:02:13 GMT
Dear All,

We have configured a portal system on Linux. In our system we uses 
connection pooling to connect to different databases. One of them is 
Oracle 9i. We have a problem with reconnection to the database.
When the database restart tomcat can't establish connection to them or 
don't try to connect.

Our configuration is like below;

*System: *Linux RH AS 3

*Servlet container:* Tomcat 5.5.23

*Oracle driver jar name is:* ojdbc14.jar*

  <Resource name="jdbc/sabanci_portlet" username="xx" password="yy" 
url="" auth="Container" 
type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" />

*Catalina log:*

No more data to read from socket
FROM ' java' in 
No more data to read from socket
FROM '' in getLeaveYear
Sep 2, 2007 11:21:18 AM org.apache.catalina.core.ApplicationDispatcher 
SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

What do you think the problem is?

Thank you very much
