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?

TIA,
Abel

FWIW - Environment:
Apache 2.2.6
Java 1.6.0_03
Java EE 5
Struts 1.3.8
Tomcat 6.0
Windows XP

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.

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?
I know that the container supports only a certain Servlet / JSP spec and I
also know these libraries are supposed to be there
I was giving the op the safest way to test TagLib functionality from a
(unknown) jar and NOT crash tomcat in the process

It would be easy to back out in case it did'nt work but to back out
something placed in server/lib ?

*Never* do that.

It will already be present in tomcat/server/lib or tomcat/lib depending
on your version, copying it to WEB-INF/lib will cause your app and web
server to behave unpredictably, and likely fail to work as intended.

Re: NoClassDefFoundError: TagExtraInfo missing?

Posted by AbelMacAdam <ab...@gmail.com>.
Hi David,

To answer your questions:

What's in your webapp's WEB-INF/lib directory, 
My TOMCAT_HOME\webapps\myApp\WEB-INF\lib contains:
antlr.jar				  commons-beanutils.jar     commons-collections.jar   
commons-digester.jar      commons-fileupload.jar    commons-lang.jar          
commons-logging.jar       commons-validator.jar     jakarta-oro.jar           
jstl.jar                  log4j-1.2.7.jar           standard.jar
struts.jar            


and can you confirm which java tomcat is running on?
C:\Program Files\Java\jre1.6.0_03\bin\client\jvm.dll


post the full stack including root causes in error messages.
Sorry, can't help you here. I was overzealous yesterday, in cleaning out my
Tomcat\webapps directory :-[. To recreate the error environment I copied a
few directories of the book [1] I'm studying from back to webapps, but now
it works as it should do. (???)

However, I did saw some other strange behavior yesterday. After copying
directories of the books sources to Tomcat's webapps directory (and
restarting the app-server) I got the display as it should be, but after a
refresh of the page I got an error message. And whatever I do, that error
persists. At the moment I get an Nullpointer exception (and I know that is a
beginners error, an uninstantiated object). So I have to find the cause of
that error. Yesterday, on the other hand, I had a primary page. So I'm
afraid I must have magical, bad weather, or any other bad influences,
playing havoc with my examples. Do you know any exorcist I can use?

And finally:

s 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? 
OrderForm is a no argument constructor

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?

Posted by AbelMacAdam <ab...@gmail.com>.
Hi David, 

I tried what you suggested (quote: "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.  If the error goes away, it may be
something funky with your Eclipse -- missing .jar file or something."): try
the app in Tomcat without Eclipse (yes, you where right in your assumption
that I used Eclipse as startingpoint of Tomcat).

At first I got the following error:
<error>
description The server encountered an internal error () that prevented it
from fulfilling this request.

exception

org.apache.jasper.JasperException: An exception occurred processing JSP page
/jsp/displayAddOrderForm.jsp at line 8

5: </head>
6: <body>
7: <html:errors/>
8: <html:form action="/saveOrder">
9: <table>
10: <tr>
11:   <td>Product:</td>
</error>

I looked in my TOMCAT_HOME/lib directory, and found the following jars with
the date stamp of last Monday:
j2ee.jar
j2ee-svc.jar
javaee.jar
I removed these files and got the following error (not the same as the root
cause of this thread):
<error>
type Exception report

message

description The server encountered an internal error () that prevented it
from fulfilling this request.

exception

Clearly, my Tomcat (and Eclipse) have issues in how I configure my system.

Re: NoClassDefFoundError: TagExtraInfo missing?

Posted by David Smith <dn...@cornell.edu>.
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.

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.  If the error goes away, it may 
be something funky with your Eclipse -- missing .jar file or something.

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 :-(.
