Обсуждение: permissions
The scene: Tony re-writing his HOWTO
The players: Tomcat4, Postgresql 7.2
The plot: writing to page the definitive guide on file permissions so
that Tomcat can talk to Postgresql via JDBC.
All that in place - the install on my development machine gives the
following result:
- I can read fronm the database. The web app functions perfectly and
with Tomcat4/Postgresql 7.2 much faster (no benchmarks, just human
"feels snappier")
- when I try to login to the administration pages I get chucked out...
javax.servlet.ServletException: Connection refused. Check that the
hostname and port is correct, and that the postmaster is running with
the -i flag, which enables TCP/IP networking.
YES IT IS FOR PETES SAKE!!!!!!
My question for the weekend is "what files/applications should have what
read/write permissions?".
In fact I feel that this is a much wider Unix/Linux question which is
one of the major problems for newcomers. I am not (a newcomer) but have
had trouble (coming from the Mac) understanding what is what since
1997...
We have three users: tony (thats me =;-{ ), postgres and tomcat4. tony
is via JDBC trying to send a login/password combination via JSP to
tomcat4. tomcat4 is validating the password against a table in
postgresql and getting the errror above.
tomcat doesn't have (decent) docs (now you know why I wrote a HOWTO)
postgresql has good docs (If I said "great" you would get sloppy...).
But there is no place where it is written in stone who should own what.
help
Cheers
Tony

So you're saying that part of your web app works fine and talks to the
database, and part of it doesn't? What are the differences between
the parts?

The error you're getting indicates that the DB connection URL used by
that part of the web app is wrong. I doubt it's a file permissions
error at all.

Each page has a Macromedia "restrict user" script which checks to se if the user is logged in. > The error you're getting indicates that the DB connection URL used by > that part of the web app is wrong.

The connection details are in Connection/name.jsp and this is included in the page on the fly. e.g. <%@ include file="Connections/frac.jsp" %> <% Driver Driverdocumentation = (Driver)Class.forName(MM_frac_DRIVER).newInstance(); Connection Conndocumentation = DriverManager.getConnection(MM_frac_STRING,MM_frac_USERNAME,MM_frac_PASSWORD); I can see your point about the connection URL but it is only in one place for the whole app. Not being able to connect at all seems logical in this case... It seems that the login part is not working i.e. the request to the password table is failing. tony, postgres and tomcat4 are all database users, tony owns the database. Really stumped on this one Cheers Tony -- RedHat Linux on Sony Vaio C1XD/S http://www.animaproductions.com/linux2.html Macromedia UltraDev with PostgreSQL http://www.animaproductions.com/ultra.html

Hmm, I don't know anything about that (I stay away from proprietary frameworks), but it sounds like it could be the problem. > > The error you're getting indicates that the DB connection URL used by > > that part of the web app is wrong.

If it was a problem with table permissions, you wouldn't be getting "connection refused", you'd be getting "permission denied". "Connection refused" has a very specific meaning--you are trying to connect to a port that no server is listening on. -Doug -- Let us cross over the river, and rest under the shade of the trees. --T.

It contains the org.postgresql.Driver jdbc:postgresql://host/database user and password information that would normally be in the header of each page. I saw a message go by that spoke of the org.postgresql.Driver bit being changed for jdk 1.4. Is that the case? As I set up my developpment server I changed the host details to the IP of my test machine. Otherwise this app is running on the clients server with no problems...

Is that the case? I dunno--still running 1.3.1 everywhere. I'm conservative. ;) Anyhow, if part of the app does connect to the database successfully, that's not the problem. > As I set up my developpment server I changed the host details to the IP > of my test machine.

I would suspect whatever Macromedia thing you're using for authentication, just because it seems to be the difference between the parts that work and those that don't.
