Re: HttpServlet not found?
yes if you're going to implement a simple servlet and you will not be implementing any (entity) beans (otherwise take servlet-api.jar off CLASSPATH and put back j2ee.jar to $J2EE_HOME\lib\j2ee.jar and place on CLASSPATH) Martin- - Original Message - From: Caldarale, Charles R [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Tuesday, November 29, 2005 11:07 AM Subject: RE: HttpServlet not found?

From: Martin Gainty [mailto:[EMAIL PROTECTED] Subject: Re: HttpServlet not found? (otherwise take servlet-api.jar off CLASSPATH and put back j2ee.jar to $J2EE_HOME\lib\j2ee.jar and place on CLASSPATH) I think you'll need to do more than that. Tomcat has a variety of class loaders, including one for each webapp, one for classes shared among all webapps, and one for classes common to the webapps and Tomcat itself. (This is in addition to the ones used by the JVM.) See: http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html for details. The picture there is quite illustrative. This creates a tree of classloaders, and you will run into problems if the same classes are present in more than one place along a particular branch of the tree. I've gotten burned too many times by the CLASSPATH environment variable to use it anymore - I'd strongly suggest you delete that variable and use explicit -cp settings where necessary. This will help to prevent any classes showing up under the wrong loader inadvertently. The gist of all this is that you don't want both j2ee.jar and servlet-api.jar to be available to either your compilations or during Tomcat execution. It's possible that you might be able to replace servlet-api.jar with j2ee.jar in Tomcat's common/lib, but I haven't personally tried it. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
