SOLVED: jdk 1.4 and Oracle drivers
Once I tapped in to the bootstrap process with my debugger a little earlier in the Tomcat startup process, I could see the conditions under which some jar files are excluded from the various class loaders. The Oracle classes12.jar file contains the javax.sql stuff, which is now included in jdk 1.4. Tomcat ignores any jar files that contain classes that were once separate from the standard jdk but are now part of it, such as the jdbc extensions, jndi stuff, etc. The solution was simply to remove the javax.sql stuff from the Oracle clsses12.jar file. john -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]. org]On Behalf Of John Gregg Sent: Thursday, June 06, 2002 4:53 PM To: [EMAIL PROTECTED] Subject: jdk 1.4 and Oracle drivers Hi all.

Re: SOLVED: jdk 1.4 and Oracle drivers
Hello John, Well, I have been using the classes12.jar in TOMCAT_HOME/common/lib. I've used it with both the JNDI javax.sql.DataSource deal provided by the Jakarta-Commons project and another connection pooler. I've never had a single problem. I've used JDK-1.3.x and JDK-1.4 and haven't had to remove any classes from anywhere. If you are having to do this with Tomcat-4.0.3, I suggest an upgrade to the latest 4.0.4 or 4.1.x betas. They are plenty stable and fix some classloading issues. I pretty much skipped from Tomcat-4.0.2-b2 to nightly builds of 4.1 because of so many classloading issues with the final release of 4.0.2 (and 4.0.3 is just 4.0.2 + a security fix).

jdk 1.4 and Oracle drivers
Hi all. Upon completing my most recent project I switched from jdk 1.3.1 to 1.4. However now I can't start Tomcat (4.0.1) because it can't find the Oracle jdbc driver class. When I first started using Oracle with Tomcat, I renamed the classes12.zip to classes12.jar. Now no matter where I put classes12.jar, I get the same error. I've tried lib, common/lib, server/lib, and webapps/project/web-inf/lib. FWIW, I have a servlet that runs at startup and tries to initialize a db connection pool. This used to work just fine and in fact still does with postgresql.jar. I even tried unzipping classes12.zip and actually jarring it up. No luck. I've traced the problem in a debugger far enough to know that the StandardClassLoader that should have classes12.jar in its scope doesn't. In fact, of all the stuff under common (classes and lib), it's missing classes12.jar and jdbc2_0-stdext.jar. Everything else is there.

Re: jdk 1.4 and Oracle drivers
Did you try adding the location of your classes12.jar to the Tomcat classpath? Look in tomcat_home/bin/setclasspath file. There should be a section near the bottom like one of the following depending on the OS: # Set standard CLASSPATH CLASSPATH=$JAVA_HOME/lib/tools.jar rem Set standard CLASSPATH set CLASSPATH=%JAVA_HOME%\lib\tools.jar John Gregg wrote: Hi all.
