OT - Tomcat and Stanford NLP POS Tagger
Hi: We are trying to implement servlet setup with Tomcat 5.0.28 and JDK 1.5.x using POS (Parts of Speech) Tagger. We can not get it to work. Unfortunately, there are no error messages in the log files for us to debug. So, I was wondering - anybody in this newsgroup was successful in getting POS Tagger (specifically Standford's) to work properly. I would appreciate any pointers. It works fine as a stand-alone application. Also, we checked their user group not much response so far. Also, googled without much success. Thanks. -vasu - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes. They are using the web application from the same computer. -Vasu "Terence M.

Re: OT: Sessions
Hi: Thanks David, Chris and Martin for the responses. I appreciate them. May be I didn't explain the situation properly in my posting. I will try to explain better - The application has pretty decent authentication mechanism that differentiates between users, roles and permissions etc. What the application need to maintain is user object information specifically - name, role, dept - to be used across other pages of the application. Since we are using session as datum - after 2nd user logs in ... the 1st user object is overwritten with 2nd user information. This creates problems specifically while logging out. In the application we are making sure that only one user login is allowed per user. This also complicates when we are attempting to create audit log of the user operations. Even though an operation is performed by the 1st user the audit log registers it as the operation performed by 2nd user. This messes up the whole point of creating audit logs. Also, for the question of Chris - there could be a need for two different users with different roles could try to login and that is when we are having this problem. Thanks again for the fe edback. regards, vasu Christopher Schultz <[EMAIL PROTECTED]> wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > Vasu, > > [EMAIL PROTECTED] wrote: > > Since we are using Session Attributes to keep track of User > > Information - this gets mangled when we try to login to application > > from the same browser (in FireFox) and Ctrl-N from IE (in other words > > the person who gets logged in will overwrite the current user's > > attribute thus losing first user information). > > Just to be sure I understand: > > You have an application that uses sessions. > > When the user logs-in in one window, then opens another window and > logs-in again, the first user's session appears to go away, and both > windows now point to the new login? > > If that's what you are describing, then it is expected behavior if you > are using cookies for session management. > > When cookies are used, the browser sends a cookie with each request.

OT: Sessions
Hi: We have an Enterprise application that uses sessions to keep track of User Information (name, role, dept). This information is used against the user when logging out, checking credentials and displaying user information. Since we are using Session Attributes to keep track of User Information - this gets mangled when we try to login to application from the same browser (in FireFox) and Ctrl-N from IE (in other words the person who gets logged in will overwrite the current user's attribute thus losing first user information). So, I am wondering whether you all have any recommendations/inputs to avoid this scenario. Thanks in advance. I did check the google and other search tools, but could not locate anything useful. regards, Vasu - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
File deletion problem
Setup: Tomcat - 5.0.28 Java- 1.4.2 OS - Windows XP Problem: Within my webapp there is a need to delete a file. When I try to delete the file sometimes it gives the message "the file can not be deleted beacuse it is being used by another user or process". The only way to get out of this situation is - stop tomcat, delete file, and start tomcat. We do not see this message always - it seems pretty random. We tried to isolate it, but unsuccessful. Any thoughts/comments? Thank You. vasu - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Are servlet name and class name required in web.xml for tomcat 5.5?
Please look into "pre-compiling" sources. You could look into - http://tomcat.apache.org/tomcat-5.5-doc/appdev/build.xml.txt and http://tomcat.apache.org/tomcat-5.5-doc/appdev/web.xml.txt When you "pre-compile" sources, it automatically generates a stub file that can be copied into "web.xml".
