Subject java.lang.IllegalStateException: Timer already cancelled
Date Tue, 06 Jul 2010 07:05:30 GMT
Hi guys.

I have a servlet that uses connection pool with the use of MySQL driver.
When I start or reload Tomcat the application works fine, then if I
redeploy my application it cannot get a connection from a DataSource object.
The following exception is thrown:

java.lang.IllegalStateException: Timer already cancelled.

java.util.Timer.sched(Timer.java:354)

org.apache.tomcat.dbcp.pool.impl.EvictionTimer.schedule(EvictionTimer.java:64)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

I have not found anything I can do with this on the internet. Perhaps I've
found that I might have a relation to
timeBetweenEvictionRunsMillis parameter ( in <Resource> configuration
section ).

I don't know if it is important, here is my configuration in context.xml
file:

<Resource name="jdbc/onlineorder"
auth="Container"
type="javax.sql.DataSource"
username="user"
password="password"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/mydb?useUnicode=true&amp;characterEncoding=utf8"
maxActive="10"
maxIdle="5"
testOnBorrow="true"
testWhileIdle="true"
timeBetweenEvictionRunsMillis="10000"
minEvictableIdleTimeMillis="60000"
/>

Did anyone face with this problem ?
