To add .....
It should happen (i.e. you need to make available those two jars) in any tomcat > 5.0. Probably those were before available in common or shared

Hi Kenneth,

I've been able to resolve the issue by, well, reading the Xerces documentation 
:-)
In addition to the xercesImpl.jar (implementation) you have to drop in the 
xml-apis.jar, too (interfaces). No idea why it used to work with only the 
xercesImpl.jar so far. I guess this was possible as a side effect of the JDK 
implementation.

It's possible you have multiple xerces' in your classpath.  Try renaming one as 
"axercesImpl.jar" to ensure it always comes first in the classpath?

Try switching to another browser; I had no problems downloading this
file with Chrome or Firefox.  (And I am not even going to ask why IE
renamed a file?!)

Just tried it, but I get this error message when I try to download it
(click on the CK.jsp file)

"Internet Explorer cannot download CK.jsp from issues.apache.org

Internet Explorer was not able to open this Internet site.  The requested site is 
either unavailable or cannot be found.  Please try again later."

I had no problems downloading CK.jar (although it comes down as
CK.zip)

I can at least reproduce it. I assume it's caused by a version of 
xercesImpl.jar being too new.
At this point, I'd try to go for the CK.jsp which can be downloaded
via
https://issues.apache.org/jira/browse/JSPWIKI-623

Hi Kenneth,

you should give more details... Which versions of JSPWiki and FCK editor? Which 
application server? Which errors?

Betreff: FCK Editor

I want to install the FCK editor for my wiki.  I have followed the instructions 
on JSP Wiki (except for installing xercesImpl.jar) and the editor seems to be 
running.  However, I get errors when I save a document.  So, I added 
xercesImpl.jar, but the application will not start with it in WEB-INF/lib.  I 
had to remove it in order to get the app to run.

Any ideas?
