Re: Tomcat 6 / Mysql / connection Pool isValid Method Error
After applying modifications for using good libraries, it works very well. Thanks a lot for your explanation and solution. Emmanuel. Connection.isValid() is a JDBC4 method and hence is only available in Java 6. Tomcat 6 has to work with Java 5 and therefore ships with a database connection pooling implementation for Java 5 that implements JBDC 3, not JDBC 4. To use JDBC 4 methods, you'll need to do the following: - Add commons-dbcp 1.4 to $CATALINA_HOME/lib - Add commons-pool 1.5.5 to $CATALINA_HOME/lib - Change your resource definition to include the following attribute: factory=org.apache.commons.dbcp.BasicDataSourceFactory Mark - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org -- View this message in context: http://old.nabble.com/Tomcat-6---Mysql---connection-Pool-isValid-Method-Error-tp30308901p30329924.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Tomcat 6 / Mysql / connection Pool isValid Method Error
Hi, I've a problem to use the 'isValid' method of Connection class with a connection pool. The java exception is: javax.servlet.ServletException: com.sun.jersey.api.container.ContainerException: java.lang.AbstractMethodError: org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.isValid(I)Z com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:346) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.cnamts.securite.filtres.FiltreSecurite.doFilter(FiltreSecurite.java:133) org.cnamts.securite.filtres.FiltreCommun.doFilter(FiltreCommun.java:128) I'm using tomcat 6.0.29 with java jdk 1.6 and netbeans 6.9. My jdbc connector jar is mysql-connector-java-5.1.13-bin.jar, placed in tomcat lib path. The declaration of my ressource in web.xml is: resource-ref descriptionDB Connection/description res-ref-namejdbc/connData/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref in my context.xml file: Context path=/QualifluxWeb antiJARLocking=true Resource name=jdbc/connData auth=Container type=javax.sql.DataSource maxActive=10 maxIdle=3 maxWait=1 username=root password= driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/test validationQuery=select 1 / /Context Others methods for conect, retrieve or update data works well. I've only a problem with isValid. What is wrong ? Or is there any other solution for checking my connection ? Thanks a lot for your help.
