Issue when using tomcat JDBC Connection Pool with a shared resource
Hi, I would like to use the Tomcat JDBC Connection Pool with a shared resource so I've read : http://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.html#Standalone and http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Resource_Links and tried to do the same but when I try to access to my servlet I get the following message: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null' at org.apache.tomcat.dbcp.dbcp.BasicDataSource.createConnectionFactory(BasicDataSource.java:1452) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1371) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:1044) at testPackage.DBTest.doGet(DBTest.java:62) at javax.servlet.http.HttpServlet.service(HttpServlet.java:620) at javax.servlet.http.HttpServlet.service(HttpServlet.java:727) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:303) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:220) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:122) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:612) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:170) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:950) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:116) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:421) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1070) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:611) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:316) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at sun.jdbc.odbc.JdbcOdbcDriver.getProtocol(JdbcOdbcDriver.java:524) at sun.jdbc.odbc.JdbcOdbcDriver.knownURL(JdbcOdbcDriver.java:493) at sun.jdbc.odbc.JdbcOdbcDriver.acceptsURL(JdbcOdbcDriver.java:307) at java.sql.DriverManager.getDriver(DriverManager.java:262) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.createConnectionFactory(BasicDataSource.java:1437) ... 25 more Environment : Win 7 Java - jdk 1.7.0.65 Tomcat - 7.0.57 MySQL - 5.1.18 Tomcat service properties: -Dcatalina.home=Y:\Programs\Tomcat\Tomcat7 -Dcatalina.base=Y:\00-Prod\data\catalina -Djava.endorsed.dirs=Y:\Programs\Tomcat\Tomcat7\endorsed -Djava.io.tmpdir=Y:\Programs\Tomcat\Tomcat7\temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=Y:\Programs\Tomcat\Tomcat7\conf\logging.properties -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -XX:MaxPermSize=512m CATALINA_HOME/lib contents ... tomcat-dbcp.jar tomcat-jdbc.jar ...

First of all, now it works fine but I would like to answer your questions... Not sure about this global attribute. I don't believe it's an attribute of the pool. Why did you add it? That's what I've read here http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Resource_Definitions The global attribute is on the ResourceLink tag, not the Resource tag. 2.) It has no url or driver set. Thanks. The issue was here and I should have read it more closely about the name property (at the same above url): name: The name of the resource link to be created, relative to the java:comp/env context. So... Before, in my context file ResourceLink name=jdbc/LocalTestDB E R R O R this jndi name doesn't exist global=sharedDataSource type=javax.sql.DataSource/ After, in my context file ResourceLink name=jdbc/TestDB - That's the right name global=sharedDataSource type=javax.sql.DataSource/ Now it works fine Note: In a way, you were right global property is no need in GlobalNamingResources (server.xml) Only global (from context.xml, ResourceLink) and name (from server.xml, GlobalNamingResources-Resource) are needed and have to match Awesome! Glad you caught that and were able to get it working. Dan You have initialSize set to 2. This should attempt to make connections when you start Tomcat. Do you see any errors at that time? There were no errors. At launching time, the pool is well created with 2 connexions in LISTENING state (netstat -an) This is unrelated, but don't set path here. The path attribute is ignore here. The path is determined by the name of the xml file, which just happens to be test-app as well. OK. path is no longer set. Do you have anything set in conf/context.xml or in your web.xml?
