Re: FW: Barracuda: Cannot load servlet name...

Hi David,

You can ignore the WEB-INF/jars directory for deployment purposes.  That 
said, it does contain some jars that are needed at runtime.  The reason 
they are in that directory rather than WEB-INF/lib is that the Sun class 
loading spec and the servlet spec forbid endorsed packages to be in 
WEB-INF/lib.  That includes some packages from javax.xml.* and org.w3c.dom 
which are in xerces-1.4.4-xmlc-2.1.jar.

Now, my only experience is with using Tomcat, not Enhydra 5.0.  So, I'll 
give you some hints on using Barracuda in Tomcat at you can map the 
instructions to Enhydra 5.0.

The following need to be put in CATALINA_HOME/shared/lib:

xerces-1.4.4-xmlc-2.1.jar
gnu-regexp-1.1.4.jar
jtidy-r7-xmlc-2.1.jar
xmlc-2.1.jar
wireless-xmlc-2.1jar
xhtml-xmlc-2.1.jar

Note: the latter two aren't needed unless you are doing wireless and/or 
XHTML DOM programming.

Everything else Barracuda related can go in WEB-INF/lib such as:

barracuda-core.jar
plankton.jar
log4j.jar

Note: the former 2 are in lib-ext (barracuda.jar contains extra examples 
and tutorials that your app doesn't require).
Using the latest log4j.jar either from Barracuda or elsewhere is fine.

One other thing to note is that Enhydra-5.0 should be able to work with the 
latest CVS.  You might want to try that.  See information on obtaining the 
latest CVS at:
http://barracudamvc.org/Barracuda/docs/cvs.html

If you do get the latest CVS, the instructions are a bit different for the 
libraries needed.  Actually, it is probably more straightforward.  Let us 
know if you have further questions.  I'm sure we can get this to work on 
Enhydra 5.0.
