I'm upgrading from tomcat 4.1.24 to tomcat 5.5.12 on WinXP. I have three applications that are deployed from this server, two of which work fine with tomcat 5.5.12, however the third which uses an oracle 9i database gives me the following error "javax.servlet.ServletException: Cannot create JDBC driver of class '' for connect URL 'null' ". Basically I've included the same details form the Tomcat4 server.xml file into the tomcat 5.5 server.xml, rediting where necessary.
Things I have tried.. Placing the context into fragment files located either inside the applications META-INF folder or under tomcat\conf\Catalina\localhost. Neither of these seemd to work for me as Tomcat could not find the apps, so I've left the context back in server.xml. Rewriting the Resource params <parameter> as elements i.e.factory="com.ora.jsp.sql.DataSourceFactory" Checked changed location of the JDBC jar file. classes12.jar catalina_home\common\lib\ AND catalina_home\webapps\[appname]\WEB-INF\lib Checked changed the server.xml service-name and engine name to match previous TC4 server.xml version. Added a Resourcelink element to the context - this is not present on the TC4 version Checked Tomcat logs. I think that Tomcat is not able to read the <ResourceParams> element, which is why the URL and driverClass are NULL. Which When I checked the Tomcat log files shows ... 16-Aug-2007 09:25:46 org.apache.catalina.core.ApplicationContext log SEVERE: action: Cannot create JDBC driver of class '' for connect URL 'null' Background info Using Apache 2.0 with mod_JK to serve pages on port 80 Java version 1.5 **** server.xml **** <!-- Tomcat 5.5 Example Server Configuration File --> <Server port="8005" shutdown="SHUTDOWN" debug="0"> <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" debug="0"/> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" debug="0"/> <!-- Global JNDI resources --> <GlobalNamingResources> <!-- Test entry for demonstration purposes --> <Environment name="simpleValue" type="java.lang.Integer" value="30"/> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" ></Resource> </GlobalNamingResources> <Service name="Catalina"> <Connector port="8009" enableLookups="true" redirectPort="8443" protocol="AJP/1.3" /> <Engine name="Catalina" defaultHost="opp-online" debug="0"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="opportunities-online" debug="0" appBase="webapps" > <Context path="/staff" docBase="oponline/staff" cookies="true" reloadable="true"> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="staff_access_log." suffix=".txt" pattern="combined" resolveHosts="false"/> <Logger className="org.apache.catalina.logger.FileLogger" prefix="oponline_log." suffix=".txt" timestamp="true"/> <ResourceParams name="jdbc/oponline" factory="com.ora.jsp.sql.DataSourceFactory" user="myuser" password="mypassword" dataSourceClassName="oracle.jdbc.pool.OracleConnectionCacheImpl" URL="jdbc:oracle:thin:@sas-test.myserver.ac.uk:1521:MYTE" maxLimit="5" /> <!-- global resource for application's context. --> <!-- <ResourceLink name="/jdbc/oponline" global="/jdbc/oponline" type="org.apache.catalina.UserDatabase"/> --> </Context> </Host> </Engine> </Service> </Server> *** end server.xml *** *** App web.xml except *** <resource-ref> <description> JNDI DataSource for [appname] database.
