Hi!
I've got the following problem - I want to dynamically display certain
information to a user, depending upon a role they've been granted (via JDBC
authorisation). how do i do that? getParameter("role") returns null.

Re: website image viewer
I suggest you use a bean for this. In the bean, read the jpeg files in the directory using a java.io.File method and then save them into a File array. Then you can go through the list by accessing each by it's array index. You not only can go to the previous or next image, but you could also directly jump to an image.

URL Rewriting Problem
Hi all, I was using Tomcat 3.1 with Apache 1.3.12 till recently. Now I changed my tomcat to Tomcat 3.2.1 and suddenly I started seeing jsessionid=* stuff in all my url's. I have coded my JSP's to support with no cookies as well (ie. urlEncoded all the links), but the thing is even tho my browser has cookies enabled tomcat seems to be encoding the urls'. This is the first problem. The second problem is that the Apache webserver is not redirecting the requests with the url having the jsessionid=* stuff. I have tried putting the URL rewriting thing given in the FAQ but even after putting that it didn't work. For you information i am giving you the thing that i put in the httpd.conf file for URL rewriting. RewriteEngine On RewriteRule ^(boats/.*;jsessionid=.*)$ $1 [T=jserv-servlet] Any help would be greatly appreciated. thanks boni p.s I have searched all the archives and the FAQ without success. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Re: Authentication to LDAP
Well, I extend SimpleRealm because I did not see securityCheck anywhere in the tomcat tree, and I assumed it was modified. And it works for me :) What is JAAS? And I am not sure if writing and intercepter qualifies as a project. I guess what we need to do is to get the wrox code to work for us and then modify it to do more general auth with ldap. I saw that there is a huge amount of bad coding in that wrox class and I am waiting to see it working so I would do a whole rewrite. I guess if you want us to launch a project for this we have to start putting the word on the tomcat-dev, rather than tomcat-users, someone would give us the heads on there. Regards. Ahmed.

Ipretty well understand everything there, except I have a blank spot inknowledge of the Tomcat architecture.

I'm assumingthat's because they were built before JAAS was defined. They're alsomuch simpler than the total pluggable-authentication-module frameworkimplemented by JAAS.

However, in an HTTP/1.1 environment (if your client supports it), Tomcat supports persistent connections. In such a case, the first three clients will grab all the available processors, and maintain those connections for later use. For clients that perform large numbers of requests, this is a huge win -- for clients that are grabbing occasional images, it is rather wasteful.

RE: Problem with Tomcat - Red Hat 7
Hi, Which/who's JDK are you using? Sun/IBM/Blackdown??? And is it Java 2 SDK v.1.3??? Also, If you installed from Henri's RPM's then they assume IBM's JDK. I'm currently working on a bit of c that will do a locate for the JDK on an RPM install so it _always_ get set right, but it'll take a while (pipe's n stuff) You can't use the java files that come with Redhat(or Mandrake) you'll need Sun's JDK 1.3 or IBM's. Make sure these are installed then check all classpaths to see they are finding the right one. Also, if upgrading then make sure the config files are accurate for the new release. You may want to make backups of your current config files then overwrite the originals with the 4.0 files. If the default 4.0 setup works then add your extra info from your 3.2 files. Good luck.

Re: tc4: catalina.home vs "catalina.install"
I've run into the exact same problem. I'd like to keep my tomcat installations separate and independent of my runtime environments. Here's what I did as a workaround: I have my own catalina startup script that runs org.apache.catalina.startup.Catalina instead of Bootstrap. In your script you'll need to explicitly add many of the catalina jars to your system classpath. It seems to be working, but it removes some of the catalina semantics found in Bootstrap. So I think a more permanent change should happen. As you suggest, there should be a distinction between the "install" directory (where the tomcat jars are) and the "run" directory, under which contains conf/, logs/, and webapps/. jeff On Sun, Feb 25, 2001 at 01:05:16PM +0100, Endre Stølsvik wrote: > Hi! > > It kind of seems to me that there is some "inconsistency" between the > catalina.home and where you actually want tomcat4 to _run_. > > I have a bunch of "installations" for my gang of developers, and each > developer have a complete env. to develop in. > > But how do I configure, "say to", catalina that "this is where you're > installed, and thus where you can find your code and stuff", and "this is > where you're supposed to run, this is your _home_".. > > Now, when I start up tomcat4, it starts to configure a lot of webapps > coming from the installation area's "webapps" folder, and tell me that > work directories are not existing, cannot be created or whatever (the > installation is made as root, I run it as me). > > Typical error line if I try to set catalina.home to where I want it to be > run from: > > Directory /devel/endre/active/SERVER/tomcat4.0-home/common/lib does not exist > > > -- > Mvh, > Endre > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, email: [EMAIL PROTECTED] > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

www authentication FYI
This is an FYI for people devloping servlets/JSP for use under Tomcat and JRun. Tomcat works fine when using the Sun recommended way of setting www-authenticate headers using setHEader followed by sendError with an UNAUTHORIZED code. JRun, on the other hand (sorry, don't know the version, but it is running Servlet API 2.1) need you to call setHeader followed by setStatus(int) with the UNAUTHORIZED code (401). If you call sendError jRun will not send the www-authenticate header and you will not be prompted for a password in IE. Netscape will prompt you for a password for "unknown" instead of for the Realm specified in the header (because the header is not sent). I am sending this because I figure a lot of people are doing devlopment under Tomcat, but their servlets may be deployed using other servlet containers...

Re: Macintosh and Java
You should be able to use IE or netscape, this is server side java so it doesn't matter if your browser supports it or not. Did you try the servlet examples? if MRJ is just a runtime then there is no compiler in it and your computer won't compile the JSP pages, try the servlets. they are already compiled. You may need to compile the JSP pages elsewhere. or find a compiler (JDK). S Lafredo wrote: > > I tried that and it did not work?

By default, standalone Tomcat listens to port 8080.
Try: http://localhost:8080/ instead. Alternatively,
edit the ..:tomcat:conf:server.xml file to change the
port.
Tomcat should be able to run fine with MacOS 9
and MRJ 2.2.4, but may occasionally encounter a glitch
with file separator. I've spotted more than one case
in the code already where folks have improperly
assumed they can use "/" as the file separator. So
watch out for possible problems in that area (mac OS 9
uses ':', mac OS X can use either ':' or '/').
Rule of thumb: When building file paths, be sure to
either use either the system property
System.getProperty("file.separator") or the public
field java.io.File.separator as the separator.
Alternatively, you should just let the File object
build paths for you:
String base = "/some/path"; // arbitrary '/' here
String dname = "mydir";
String fname = "myFile.txt";
File f = new File(base);
f = new File(f,dname);
f = new File(f,fname);
The above would build "/some/path/mydir/myFile.txt" on
unix. On a mac (assuming base=":some:path", the
result would be ":some:path:mydir:myFile.txt"

If you want to run Apache, you will need to use Darwin
or Mac OS X public beta while waiting for Mac Os X.
If you don't need Apache, then tomcat itself should
run fine on Mac OS 9. MRJ 2.2.4 has many 'Java 2'
apis added on top of the offic 1.1.8 spec.

If you have at least a 500MHz G3 box, running Apache
on Linux or WinNT inside Virtual PC v4 should be
actually viable unless you expect a lot of traffic
(i.e. it should be fine for development).

JSP code wont run
Hello All, I'm a newbie and would appreciate help... I've developed a few jsp pages and it seems to still caache the old servlets that Ive run before and wont update with the new changes even when I saved it to the hard drive and overwrote the old .jsp file. I think it's a caching issue... am I right? And how do I fix it? Also, I did the shutdown.bat and startup.bat files to restart tomcat with no effect...

Whether or not a stack trace gets printed is not a
function of the logging level. A stack trace will be
printed under the following conditions:
If an uncaught exception makes it through to the VM
runtime, a trace will printed by the runtime to
standard err (System.err).
If a catch() block in your code (or someone else's
code higher up the call chain) catches an exception
and proceeds to explicitely print the stack trace.
Note - if you are throwing an exception that you
expect to show a trace at the runtime level, it is
possible that "someone else's code" is catching it and
ignoring it (a very bad practice but all too common).
Finally, you can always just create a Throwable object
and print the stack trace yourself.
To display the stack trace of a Throwable object to
System.err, you can just use the
Throwable.printStackTrace() method. Thus, in your
code you might put:
try{
// do something that throws a FooException
}catch(FooException e){
e.printStackTrace();
}
Or, for debug purposes to find out how you got to your
code without relying on some Exception being thrown,
just do the following:
//...do stuff...
(new Throwable()).printStackTrace();
//... continue doing other stuff...
The only problem with the above technique is that
there is no control over formatting or where the
message goes. It always goes straight to stderr. To
change that, you can capture the stack trace in a
String using a simple method like so:
/**
utility function for retrieving the stacktrace of
a Throwable object as a String for easy
manipulation.
Useful for debugging. Returns "" if t==null.
@param t a Throwable object.
@return a String representation of the stack trace
for t.
*/
public static String getStackTrace(Throwable t){
if(t==null){
return "";
}
StringWriter sw = new StringWriter();
t.printStackTrace(new PrintWriter(sw));
return sw.toString();
}
Put the above method into a utility class (i.e.
'MyUtils' and then you can always grab the trace for a
throwable anywhere in your code with:
String trace=MyUtils.getStackTrace(new Throwable());
That way, you can display the trace in an html page,
or search it or make it part of the message nested
inside another exception, or whatever.
Using stack traces like this is a very useful tool for
developing and debugging code, or for simply trying to
understand other folk's code. Visual Debuggers are
useful too, but less reliable and not ubiquitous.
One tip: You refer to wanting to print the trace to
'standard out'. Just a bit of developer's philosophy,
but:
Standard out - for program _output_ (i.e., the actual
product of the application). Example: 'more'
displays text from files to stdout.
Standard err - for program _debug_ and _error_
messages. Example, if 'more' can't find the file
indicated, it prints an error message to stderr.
The distinction is important because conceptually,
these are two different io streams. By default,
System.err prints to the same OutputStream as
System.out, but that is not necessarily always so.
You can easily redirect one or the other using
System.setErr() or System.setOut(). By always sending
your debug and error messages to System.err, you
should not have to worry about forgetting to remove
all your debug statements and accidentally corrupting
your program's output.
Just my $.02. Take it for what it's worth. :-)
I hope this is helpful.

RE: Secure MessageDigest Login using JSP
And IE5 and Mozilla6 are supposed to support digest authentication so you might only need to implement something as a fallback (or if it is an intranet/extranet project specify only those browsers) Reading the rfc (rfc 2617) on digest authentication is a good idea if you are thinking of rolling you own. HTH -Original Message-From: Brett Bergquist [mailto:[EMAIL PROTECTED]]Sent: Saturday, February 24, 2001 7:13 PMTo: [EMAIL PROTECTED]Subject: RE: Secure MessageDigest Login using JSP Ryan, I did something like this in my current project. The currently supported authentication forms do not support this, but I needed it. Since my application UI is Java Applet based, I was able to use the message digest API's in Java 2 to do this. What I did is this: Modified all of my pages that I need to protect to see if the user is logged in and if not, forward the request to a Login JSP page, keeping track of the original request destination. Created a Login JSP page which contained a Login applet. The Login applet provides an area for the user to enter the username and password. I use this along with the session ID for the session and compute the digest hash. The digest hash, username, and session ID is passed to a Login servlet using HTTP POST. Created a Login servlet which receives a digest hash, username, and session ID in its POST handler. The session ID is validated against the current session. The username is used to lookup the user authentication information is a database and retrieves the user's password. I then compute the digest hash using the supplied username, session ID and the password lookup. If this hash is the same as the one passed in the POST message, then the user is authenticated and logged in and redirected to the orignal request destination. I probably could have implemented an Interceptor or such to do this, but I was fairly new to Tomcat and this seemed the easiest way and as a side benefit it is not Tomcat specific. The only real downside is having to protect each page individually. If you are not using an applet on the client side, you could still compute an MD5 hash in Javascript and do something similar.

Tomcat4 Authentication over Apache 1.3 does not work
Hi, I use the tomcat4 rpm from Henri Gomez I've setup the apache 1.3 Module and can succesful browse the examples over the apache webserver. I've setup a additional line in httpd.conf: WebAppMount manager warpConnection /manager and I've setup tomcat-users.xml When i browse over the apache webserver with http://myhostname/manager/ the authenticaiton prompt comes up, but I can not login. If i try this not over the apache webserver and use the tomcat4 engine direct then i can authenticate and it works. What i am doing wrong? Regards Dietmar P.S.

tc4: catalina.home vs "catalina.install"
Hi! It kind of seems to me that there is some "inconsistency" between the catalina.home and where you actually want tomcat4 to _run_. I have a bunch of "installations" for my gang of developers, and each developer have a complete env. to develop in. But how do I configure, "say to", catalina that "this is where you're installed, and thus where you can find your code and stuff", and "this is where you're supposed to run, this is your _home_".. Now, when I start up tomcat4, it starts to configure a lot of webapps coming from the installation area's "webapps" folder, and tell me that work directories are not existing, cannot be created or whatever (the installation is made as root, I run it as me). Typical error line if I try to set catalina.home to where I want it to be run from: Directory /devel/endre/active/SERVER/tomcat4.0-home/common/lib does not exist -- Mvh, Endre - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
tc4: "No processor available, rejecting this connection"
My config is like this: This gives me lots of left out small gifs, maybe a leftout stylesheet, or the whole document.. or whatever. I realize that there's not many processors configured here, but why does it start to reject connections? It should stack them in a queue, shouldn't it?

Thanks Karl for a very eloquent albeit terse reason for belonging to the group. Let me make a few things clear. 1. The Newbies UNITE TUG was started because email lists are not the ideal way of learning a new technology. I've been coding for almost twenty years and from my experience User Groups are the best way to get determined users up to speed quickly. 2. User Groups also allow topic branching that could never be tolerated in a mailing list. Could you imagine sharing emails on this list that went from TomCat to Java Math Classes to developing financial derivatives code. It doesn't work on an email list. Lists have to be specific. 3. We have five,people on the NEWBIE TUG so far (soon to be fifteen). If we can lessen the amount of usual posts, thus sparing some of the more experienced users, that's a good thing. Lastly, This is to the folks who already agreed with the NEWBIE TUG concept. Thanks. From reading your emails, it seems like we've got some motivated people going into this thing. If your a newbie and want to share and learn, JOIN our TUG. Lastly, I don't want any flame stuff around here. If you don't want to join or think we're crazy, please don't bash the concept. I'll tell you a thing or two about user groups. People have started companies from inside UGs, people have gotten friends from belonging to UGs, users in groups have even gotten married. It's an import concept in the software development industry. While I was composing this post Ashant posted and I do need to add this final note: Ashant does bring up a good point that should be addressed by our Virtual TUG. At some point, we should ask an experienced TomCat developer or User to join or at least give us some guidance.

RE: Tomcat deployment
When Using two tomcat with two server.xml files on the same machine I have 2 problems: 1.
