Hi, I had a look at the tomcat dbcp documentation and found that it is possible to retrieve the underlying connection.
As described here http://commons.apache.org/dbcp/configuration.html The problem i am getting now is that i still cannot cast the class properly to get the underlying connection. As described in the docs i added the following property in the datasource definition [code] accessToUnderlyingConnectionAllowed="true" [/code] My datasource definition now looks like this [code] <Resource name="jdbc/testdb" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:@10.10.10.10:1521:testdb" username="testuser" password="testuser" maxActive="20" maxIdle="10" maxWait="-1" accessToUnderlyingConnectionAllowed="true"/> [/code] And change my code slightly to be [code] Connection conn = ds.getConnection() Connection dconn = ((DelegatingConnection) conn).getInnermostDelegate(); [/code] The problem i have now is i am getting a class cast execption on the second line (where i am trying to getInnermostDelegate(). Here is the error i am getting [code] java.lang.ClassCastException: org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper at com.bt.ccs21.data.accessors.ConsignmentDAO.submitDeclaration(ConsignmentDAO.java:250) at com.bt.ccs21.presentation.events.consignment.search.SubmitDeclaration.midAction(SubmitDeclaration.java:105) at com.bt.ccs21.presentation.events.CCS21EventAction.execute(CCS21EventAction.java:67) at org.apache.struts.chain.commands.servlet.ExecuteAction.execute(ExecuteAction.java:58) at org.apache.struts.chain.commands.AbstractExecuteAction.execute(AbstractExecuteAction.java:67) at org.apache.struts.chain.commands.ActionCommandBase.execute(ActionCommandBase.java:51) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:190) at org.apache.commons.chain.generic.LookupCommand.execute(LookupCommand.java:304) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:190) at org.apache.struts.chain.ComposableRequestProcessor.process(ComposableRequestProcessor.java:283) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:462) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) [/code] Thanks On Thu, Oct 9, 2008 at 5:53 PM, Ziggy <[EMAIL PROTECTED]> wrote: > Hi, > > I originally only had it on $TOMCAT_HOME/common/lib but it didnt work. > I only put it on both locations to test it out. > > I have now removed the copy from $APPLICATION_ROOT_DIR/WEB-INF/ lib/ and i > still have the same problem described below. > > Thanks > > > On Thu, Oct 9, 2008 at 5:35 PM, Caldarale, Charles R < > [EMAIL PROTECTED]> wrote: > >> > From: Ziggy [mailto:[EMAIL PROTECTED] >> > Sent: 2008 October 09, Thursday 11:12 >> > org.apache.tomcat.dbcp.dbcp.PoolingDataSource >> > >> > I have placed the jdbc driver on both the following directories >> > [code] >> > $TOMCAT_HOME/common/lib/ >> > $APPLICATION_ROOT_DIR/WEB-INF/lib/ >> >> > [/code] >> >> Never, never, never put the same class(es) in more than one location in a >> given branch of the classloader tree. >> >> Since you're using Tomcat to manage the DB connection pool, the .jar file >> containing the JDBC driver classes must be placed in common/lib. >> >> - Chuck >> >> >> THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY >> MATERIAL and is thus for use only by the intended recipient.
