Re: NoClassDefFoundError: TagExtraInfo missing?
Cool... I see your tomcat lib directory is back to the default
distribution. What's in your webapp's WEB-INF/lib directory, and can
you confirm which java tomcat is running on? I would like to be sure
it's not J2EE. It should be the Java 1.6.0_03 you listed in your
original post. Lastly, post the full stack including root causes in
error messages. The two stacks you posted below look like they had
additional information in a root cause.
As far as the last stack you posted (and this is just a guess), is
app04a.form.OrderForm a true JavaBean with a no argument constructor?

Re: NoClassDefFoundError: TagExtraInfo missing?
Not obviously. J2EE contains all the stuff tomcat contains plus some. I suspect the duplication of the servlet and jsp api classes in both tomcat and j2ee is causing the issues. The OP should either 1) use a j2sdk w/ tomcat or 2) use j2ee w/o tomcat, but never j2ee with tomcat. Adding the jsp-api to the webapp's WEB-INF/lib directory compounds the issue further rather than cleaning anything up. --David Martin Gainty wrote: Obviously its not there otherwise he wouldnt be getting the error in other words copying some jar (you dont know anything about) to server/lib is the preferred action?

Just out of curiousity, are you trying to run your webapp from within Eclipse? If so, try it without Eclipse -- deploy it to your installed tomcat and see if the error continues.

Re: NoClassDefFoundError: TagExtraInfo missing?
Sorry Martin, but bad advice. In recent versions of tomcat, jsp-api is provided in the /lib directory of tomcat. If you have your own in your webapp (or in the jave environment for that manner), please remove it as it will cause many a wonderous error. Also tomcat does not work with j2ee as j2ee comes with it's own copy of a servlet container and the two will clash with each other. Replace your Java EE environment with the java sdk or java jre environments to use tomcat. The bottom line is jars in tomcat can only exist once along any classloader branch. If it's in the JVM, it can be in tomcat's /lib or the webapp's /WEB-INF/lib directories. If it's in tomcat's /lib, it can't exist in the webapp. Come back with a complete stack trace including any root causes of your problem once those are fixed. --David Martin Gainty wrote: Abel put jsp-api.jar in /WEB-INF/lib M- - Original Message - From: "AbelMacAdam" <[EMAIL PROTECTED]> To: Sent: Monday, December 24, 2007 6:58 AM Subject: NoClassDefFoundError: TagExtraInfo missing?

Re: NoClassDefFoundError: TagExtraInfo missing?
Hi, Thanks for the feedback. I just saw that both el-api.jar and jsp-api.jar are part of my TOMCAT-HOME/lib directory. And these jar files are part of my 'Java Build Path' in Eclipse. So I'm still scratching my head :-(.

NoClassDefFoundError: TagExtraInfo missing?
Hi, I'm trying to bootstrap my knowledge on Struts. As I tried an example I got the following error: java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagExtraInfo Searching on this error I got the impression I needed j2ee.jar. I downloaded and installed the Java EE 5 SDK from Sun. In Eclipse (Europa) I I added a 'J2EE' library to my Libraries in my 'Java Build Path'. This library contains the following jar files: javaee.jar (and that jar file includes a javax/servlet/jsp/tagext/TagExtraInfo.class!) j2ee.jar j2ee-svc.jar After rebooting Tomcat (6.0) in Eclipse I still got that error. What do I need to do the remove this error and continue with the example?
