authentication problem using manager URLs from a script
Hello -
I want to stop and start a context from a Java program running as
a cron job. I have tried
http://<host>:<port>/manager/stop?
username=<manager-role username>&
password=<password>&
path=/<context path>
(without the carriage returns, of course). This yields me a 401. Reading
the manager app documentation, it doesn't actually explain how to
authenticate from a script. How do I do it?
I apologize if this question has been asked before. I studied the list for
a couple of hours before giving up;

Thanks for the pointers. I ended up picking up code from the
Tomcat source of org.apache.catalina.ant.AbstractTask and using that to do
Basic Authentication. I've got it working now.

This isn't how BASIC authentication works. For details see RFC 2617 or
for the quick solution see the applyHttpBasicAuthentication method in
http://marc2.theaimsgroup.com/?l=fop-cvs&m=114069081209918&w=2
Alternatively take a look at HTTPClient that will hide all this fun
and games.

I have looked at the manager app how-to, and it doesn't describe
how connect from a script. I have this
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
private static String stop =
"http://myhost:8080/manager/stop?path=/myapp";
public static void main(String[] args) {
try {
URL stopURL = new URL(stop);
URLConnection cnxn = ustopURL.openConnection();
cnxn.setRequestProperty("username", "user");
cnxn.setRequestProperty("password", "password");
cnxn.connect();
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
but am still getting 401. Do you have any suggestions? I have a complex
app that does a number of things before stopping and starting a web app,
and I don't want to have to cram the whole thing int Ant.
Any help appreciated;

What on earth has webdav got to do with this?

The user name and password get passed as HTTP headers. The easiest way
is probably to use the provided ant tasks. See the bottom of
http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html for details.

You have to use the webdav application provide from tomcat. Check under
$tomcat_home/webapps/webdav/web.xml. there is a line commented out that
states some property of read-only = false. by default it is read-only and
you have to manually turn it on.
