java.lang.NoClassDefFoundError: org/apache/xerces/dom/ElementImpl

 Hi!

 Tracker of forge.objectweb.org seems not to use it.
 So, I contribute this patch to this Mailing List directly.

 In my environment, Barracuda2(Subversion version) will
generate the following errors.

 URL: http://localhost:8080/Barracuda2/GetLoginScreen.event
 exception: javax.servlet.ServletException: Servlet
execution threw an exception
 root cause: java.lang.NoClassDefFoundError:
org/apache/xerces/dom/ElementImpl

 This reason is because xercesImpl-*.jar is not copied to
WEB-INF/lib.

 This pacth can solve this problem.

 Thank you.

Hi,

First of all, thanks for your input.

The problem with xerces is that it is a quite ubiquitous
library...
So I think barracuda.war take for granted that xerces will
be available
at a broader level in the servlet environment (in Tomcat
common libs, or
even in jdk endorsed libs, or somewhere...)

But I also had to add xercesImpl in my build.xml, so I must
admit this
might be a problem.

Maybe Jake would like to comment on this ?

Franck is right.  If you want to add XercesImpl.jar to your
own application, 
that's fine.  But we won't be changing Barracuda's build to
do it.  Why?  Ant 
ships with XercesImpl.jar and xml-apis.jar in ANT_HOME/lib
(you should 
overwrite these with newer versions).  For a long time,
Tomcat shipped with 
it.  It and xml-apis.jar are global libraries.  JDK1.4+
ships with older 
versions of xml-apis and JDK1.5 ships with a modified
version of Xerces, 
packaged in the com.sun.xerces namespace.  For a deployment
system, such as 
Tomcat, you should put xercesImpl.jar (2.9.0+) and
xml-apis.jar (1.3.04+) in 
an endorsed directory.  This can be either Tomcat's (or
other appserver's) 
endorsed directory or the JDK's own endorsed directory.  If
you don't, you 
risk an older version of xercesImpl.jar already in an
endorsed directory 
overriding the version in your WEB-INF/lib directory.

Hi,

well, I think I should put this into the 'Getting started'
doc section,
as xercesImpl.jar and xml-apis.jar are not mentionned
here...
By the way, I will also try to update dependencies version
all around...

Hi,

I just updated the docs ('using_barracuda' and 'faqs'
sections) to
reflect the need for xercesImpl and xml-apis somewhere in
the
environment. I mainly copied Jakes note from the Readme in
the jars
directory.

Andreas, I hope this answers your questions.

Thanks again for your input and don't hesitate to ask, would
you need
any supplementary input.

Reagards,

Franck
