Hi, I had a problem before with this upgrade scenario using the Oracle drivers, and asked the list. I was asked if the JAR was in $CATALINA_HOME/lib - it was - no further ideas. I have never had a problem before with JDK 4 or 5 on TC5.5, just with JDK6 and TC6, so I temporarily abandoned my upgrade. I only had the problem with *cross-context* webapp invocations, in this case via Liferay's WAR. Maybe that's significant. If I used a JSP for JNDI lookup and requested the page directly, with the DBCP kit in WEB-INF/lib, all was OK. Here's my message again:
When doing cross-context invocations of a portlet in Liferay that references container-managed Datasources by JNDI, I get:- Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver' java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver The driver JAR was in <SERVER>/lib. ($CATALINA_HOME/lib) When I put dbcp, commons-pool and the driver JAR in the portlet WAR file and create the Datasource myself, no problem. When looking up the container Datasource directly from a JSP (no cross-context webapp invocation), no problem. I tried upgrading to a later JDK 6 Oracle 11i driver, but no luck, the problem was not specific to Oracle's driver version. Other people have had classloading problems too, and said it's a bug in TC6 with use of Class.forName() So I stuck with TC5.5 on JDK 5 for the moment - the problem's blocking our upgrade path. Is this a known fault with TC6 that will be fixed? --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
