Hi all, I premise that I am approached to the apache Geronimo/Tomcat world only recently and I don't know much details about those servers.
Ok, now here's my problem: On Geronimo 2.2.1 + Tomcat6 I create a mysql database pool via the wizard in order to connect a war to my mysql db. I used mysql-connector-java-5.1.12-bin.jar as driver (or connector?). I also, as described in the "usage" link of the pool (on the console), added to the war the geronimo-web.xml file. web.xml: ============================================ <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd";> <servlet> <servlet-name>Extractor</servlet-name> <servlet-class>database.Extractor</servlet-class> </servlet> <servlet-mapping> <servlet-name>Extractor</servlet-name> <url-pattern>/Extractor</url-pattern> </servlet-mapping> <session-config> <session-timeout>30</session-timeout> </session-config> <resource-ref> <res-ref-name>mysqlpool</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref> </web-app> ============================================ geronimo-web.xml: ============================================ <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.1";> <environment> <moduleId> <artifactId>TestPool2</artifactId> </moduleId> <dependencies> <dependency> <groupId>console.dbpool</groupId> <artifactId>jdbc_local_mysql</artifactId> </dependency> </dependencies> </environment> <context-root>/TestPool2</context-root> <resource-ref> <ref-name>mysqlpool</ref-name> <resource-link>jdbc/local_mysql</resource-link> </resource-ref> </web-app> ============================================ Servlet: ============================================ ... InitialContext ctx = new InitialContext(); String resourcename = "mysqlpool"; DataSource ds = (DataSource) ctx.lookup("java:comp/env/"+resourcename); con = ds.getConnection(); String sql = "select message from log.mito_logbook limit 10"; PreparedStatement pstm = con.prepareStatement(sql); ResultSet rs = pstm.executeQuery(); while(rs.next()) { out.println("<p>"+rs.getString(1)+"</p>"); } ... ============================================ After the war deploy (no problems with it), I tried to run the application and I got the following (Extractor is the name of my servlet): ERROR [[Extractor]] Servlet.service() for servlet Extractor threw exception java.lang.NoClassDefFoundError: org/apache/tomcat/jdbc/pool/DataSource at database.Extractor.processRequest(Extractor.java:50) at database.Extractor.doGet(Extractor.java:104) at javax.servlet.http.HttpServlet.service(HttpServlet.java:693) at javax.servlet.http.HttpServlet.service(HttpServlet.java:806) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.geronimo.tomcat.GeronimoStandardContext$SystemMethodValve.invoke(GeronimoStandardContext.java:420) at org.apache.geronimo.tomcat.valve.GeronimoBeforeAfterValve.invoke(GeronimoBeforeAfterValve.java:47) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:555) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:396) at org.apache.geronimo.pool.ThreadPool$1.run(ThreadPool.java:214) at org.apache.geronimo.pool.ThreadPool$ContextClassLoaderRunnable.run(ThreadPool.java:344) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I really don't know what's going on. Well it's a "No Class Definition", but I cannot understand, the mysql connector (the jar I mentioned above) doesn't provide the tomcat jdbc DataSource class too? I am missing some basic connector-related concepts? -- Michele.
