Re: [Jetty-support] Jetty directory usage

[Chaudhuri, H. <Hir...@so...>]

Hi, Jan.

Thank you for hint. I just tried to create a lib/ext directory and move
my jar into that one, but I still have the same result. It just seems to
me that Jetty 5.1.8 does not use the lib directory at all. Placing my
jar either in the ext directory or in the webapps' WEB-INF/lib is ok
though.

>From tomcat I'm used to have three directories: The webapps'
WEB-INF/lib, the shared/lib and the server/lib directories, while only
the first two are visible to a web application. Does jetty come with a
similar model?

Maybe I will try to turn off JSP as those two webapps are servlet based
only. But that will only fix xerces to get along....

Hiran,

Individual jars in $JETTY-HOME/lib will be put on the classpath.
However, that is quite untidy, leading to a proliferation of jars at the
top level of the lib. The tidy way to do it is to create subdirs under
$JETTY-HOME/lib/ext and put your jars into the subdir structure, which
can be as deep as you want.


Regarding xerces, that is one of the biggest PITA for web containers -
every webapp wants to use a specific version and that was one of the big
drivers for the crazy inverted classloading hierarchy of the servlet
spec.=20
Note that Jetty itself does not use xerces for parsing web.xml, it is
the JSP engine that requires this. So, if you can turn off JSPs, then
you're sweet :-) If not, then either you can try and make your webapps
use the same version of xerces that the JSP engine uses, or vice versa
(althought it sounds like you've tried that). Failing that, you are
going to have to live with a copy of xerces in each.

cheers
Jan
