Alternatively, have you try putting it inside the /lib directory of your webapp? It will then only be accessible to that webapp tho.
yes, I tried that, and it works. woopie. to extend the WebdavServlet, I've copied servlet-common.jar servlet-default.jar servlet-webdav.jar and catalina.jar (oops) from the server/lib into my /WEB-INF/lib
ugly, but it compiles and runs. it appears WebdavServlet was not intended to be extended by the authors, because quite some usefull things are 'private' :-|
now .. let's see if i can add the missing PROPPATCH support :-)
I found this old thread about extending WebdavServlet, in which Andreas Probst notes his webapp cant load classes from the $CATALINA_HOME/servlet/lib/ dir.
this url
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader- howto.html
makes it clear why.
but now: how should I extend WebdavServlet inside my webapp ? If i put my own classes in the org.apache.bla package, it can't load the classes from my webapp, ofcourse.
should I copy all jar files from $CATALINA_HOME/servlet/lib/*jar to my webapps /WEB-INF/lib ?
that should work, but it sounds ugly.

Hi all,
does Tomcat really look into tomcatdir/server/lib? For me it seems
Tomcat doesn't.
This directory is only visible to the classloader for Tomcat itself, not for webapps. There is a special rule that makes servlet classes in package "org.apache.catalina" available to webapps anyway, however, which is why the standard WebdavServlet (as well as the other Tomcat features that are available via servlets) can be loaded.

Thank you Craig.
Could you please tell more about the rule or give a pointer. The
class-loader-info of the Tomcat-Docu says nothing about the rule, but
says, that "These classes and resources are TOTALLY invisible to web
applications".
Actually, the rule is very simple, and it is there in the docs. Look at the picture of the class loader hierarchy in the Tomcat docs:
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader- howto.html
The classes that are visible to a web application are those in the class loader for that webapp, and any of it's parent class loaders. In other words, an application can see the "WebappX" class loader for itself, plus the "Shared", "Common", "System", and "Bootstrap" class loaders. It can*not* see the "Catalina" class loader.
thanks,
