1. It is possible to inject user's URL factories into
DirContextURLStreamHandlerFactory of Tomcat 7. See static method added
in
http://svn.apache.org/r1078601
https://issues.apache.org/bugzilla/show_bug.cgi?id=26701
2. java.protocol.handler.pkgs shall work, but it have been a long
time since I last experimented with that.

3. Exactly how you did it?
4. Modifying catalina.sh is usually a bad thing.
Modifications shall go into a "$CATALINA_BASE/bin/setenv.sh" file.

5. Are those the Java version that you are using? Are they visible to
the class loader (e.g can you load the class in any test JSP page?)

but nothing.
Is your webapp the ROOT one?
If it cannot be in $CATALINA_BASE/lib then put it elsewhere and add it
to CLASSPATH variable in setenv.sh.
6. Is "jespa" the correct value for that property? It shall be a
correct Java package name.
