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) java.util.Timer.schedule(Timer.java:222) org.apache.tomcat.dbcp.pool.impl.EvictionTimer.schedule(EvictionTimer.java:64) org.apache.tomcat.dbcp.pool.impl.GenericObjectPool.startEvictor(GenericObjectPool.java:1647) org.apache.tomcat.dbcp.pool.impl.GenericObjectPool.setTimeBetweenEvictionRunsMillis(GenericObjectPool.java:843) org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1173) org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880) basis.onlineorder.commons.dao.UserDAOJdbcImpl.getUsers(UserDAOJdbcImpl.java:133) org.apache.jsp.users_jsp.getUsersList(users_jsp.java:31) org.apache.jsp.users_jsp._jspService(users_jsp.java:164) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:377) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) 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&characterEncoding=utf8" maxActive="10" maxIdle="5" testOnBorrow="true" testWhileIdle="true" timeBetweenEvictionRunsMillis="10000" minEvictableIdleTimeMillis="60000" /> Did anyone face with this problem ?
