tomcat's webdav and "Premature End of File" error ...
Hi , I am testing Tomcat's webdav and could open the webdav as a web folder. When I double clicked on a MSOffice (MSWord, PPT, etc.) from the browsed folder, the files could be opened fine. However, with any other files (zip, pdf, txt, xml), it gave me the error : [Fatal Error] :-1:-1: Premature end of file. org.xml.sax.SAXParseException: Premature end of file. at org.apache.xerces.parsers.DOMParser.parse(Unknown Source) at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source) at WebdavServlet.doPropfind(IMOWebdavServlet.java:356) The exception was thrown at Document document = documentBuilder.parse (new InputSource(req.getInputStream())); in webdavservlet's doPropfind() . Is there a solution for this problem ? Thank you very much . Another problem is that , every time I double click on a file, it asks me to log in again with the login dialog box (even though I already logged in after browsing to the web folder). - Chinh - Do you Yahoo!?

Please Help : STRANGE WEBDAV problem with the setting in WEB.XML
Hi, If you install Tomcat 4, you should be able to open webdav as a webfolder by doing : http://localhost:8080/webdav (open as a webfolder). However, if I change the webdav servlet name to another name (eg. "mywebdav"), and try to open http://localhost:8080/mywebdav, it gave me the error "cannot open http://.. as a web folder" !. Is there a hard-coded path somewhere ? Does the implementation of webdav servlet have some kind of "forward" to "/webdav" Thanks . - Chinh mywebdav org.apache.catalina.servlets.WebdavServlet debug 0 listings true readonly false mywebdav / - Do you Yahoo!?

Re: AUTHENTICATE question with WEBDAV.
Thanks, Bill . In BasicAuthenticator.java , the authenticate() method gets the username and password by calling : String authorization = request.getAuthorization(); which gets the value from the "authorization" request header, which is the value to be base 64 encoded of username and password. My goal is to set this request with the correct "authorization" header so that I can bypass the "Login dialog" if the username and password are already got before the request (before the user enters http:///webdav to run the webdav servlet). I have no clue how to do this ... What's the purpose of a VALVE class ? Thanks. Bill Barker <[EMAIL PROTECTED]> wrote: The simplest solution is to enable the SingleSignOnValve. This allows any login to any Context to be passes to any other Context. If this doesn't meet your needs, then you can: 1) Write a custom Valve to pickup the User. 2) Write a custom Authenticator that knows how to pickup the User.

WEBDAV and FORM-Based Authentication
Does anyone know if it is possible to have a FORM-based authentication with webdav servlet (which is open as a "web folder"). I have tried, but unsuccessfully. If a servlet runs in a regular way (HTTP://), the form log-in page is displayed. However, if the webdav servlet is open the "webdav" way (as a "web folder"), the form is never displayed ?

getParameter does not work with webdav servlet
Hi
I found an interesting problem ...
If I run http://../webdavservlet?param1=YYY
req.getParameter("param1") returns YYY ONLY IF I run the webdav servlet in the
regular way (open IE -> type in the URL and return). If I run webdav servlet the
webdav way (File | Open choose Open as webfolder as you enter the same URL),
req.getParameter("param1") returns NULL .
Do you have any idea ? Is it possible to get the parameter from webdav servlet if we
run webdav as a webfolder ? Thanks.

AUTHENTICATE question with WEBDAV.
I have a question about WEBDAV and How authenticate works. If i have this in web.xml BASIC MyCustomRealm It will get an Popup Log in dialog, and it will invoke my realm's authenticate() method, with username and password being entered by the user. However, I do not want the log in dialog to pop up in all cases. There's a case that the user is already authenticated BEFORE he tries to run the webdav servlet, and in this case, he wants to bypass the log in dialog. Do you know How to pass in the Authenticator class some information so that it doesn't need to invoke the login dialog if the user is already authenticated ? What information would the authenticator need ? Thanks. - Chinh - Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month!
Re: REALM question - please help
Thanks for your help . I'm new to TOMCAT , so I may have some confusion. I thought it's the way that TOMCAT does. We have to use REALM to authenticate as we define this in web.xml : BASIC MyRealm It will pop up a log in box, and Realm's authentication method will does the authentication. After the Login , it 'll call the Servlet's service(). In the Realm class, which extends org.apache.catalina.realm.RealmBase, there is no access to HttpRequest, Response, or Session at this point . How do I store a data member of the Realm class some where (?) so that my servlet can access to it ? Or is it something that should never be done ? What'd be an alternative solution ? I don't think Filter serves the goal that I describe above, am I correct ? Thank you very much. - Chinh Bill Barker <[EMAIL PROTECTED]> wrote: I agree with Jean-Francois that the design is less than perfect ;-). You should probably re-think it. However, I'm willing to give you more than enough rope to hang yourself ;-). 1) If your custom Realm is configured under a , then simply have if save an instance of itself into the Session. 2) If not, or otherwise, have it set a request-attribute with itself as the value.

REALM question - please help
I have a tomcat question for you . In Tomcats server.xml, we define a realm (only ONE) When tomcat starts, I think it will instantiate a realm object of this type . I am trying to find a way to access this realm object in my servlet (the servlet that starts after the realm's authentication succeeds). Theres a method getRealm() from org.apache.catalina.core.ContainerBase , but how would we get this ContainerBase ? Does Tomcat have some kind of global object of this type ? Thank you .

TOMCAT webDAV question
Hi I am trying to use Tomcat's implementation of WEBDAV for my file upload requirement .After deploying webDAV as a web folder, I need to open to webdav as a webfolder, and upload files by dragging them over from Windows Explorer to IE . By default, Tomcat's webDAV does not have a configurable property where we can set the rootpath of where the files will be uploaded to (eg. C:/tmp). I think TOMCAT's implementation "PUTs" the file based on a relative path to the webdav web app directory . Right now, when you drag a file over to the webdav folder, it's treated as a "PUT" method, and it will invoke "DefaultServlet"'s service() to do the uploading. Do you know if it is possible to set an absolute root path with Tomcat's webDAV ? if it's not configurable, how would we change the code to do this ? I have been looking at WebDAVServlet, but found no solution yet how to control where the files will be sent to . - Ch
