Re: Why use SOAP in Java

Since SOAP is based on RPC, I think the best question may be asked, why use RPC for client-server application? Well... let's put it another way: Why not use SOAP and/or RPC for client-server applications? Isn't RMI per definition also sort of RPC if you keep it straight Java? Good thing about doing RPC in a SOAP-like way is that you virtually can create a client-server system without requiring any of the both parts to be implemented in Java, as it is easy to, say, call server-sided Java procedures from a system implemented in Python, .NET, Perl or whatever could come to your mind...

semi-OT: lambdaprobe and logging on tc6?
Folks; earlier some kind souls on this list recommended me to check out lambdaprobe.org to fulfil my tomcat management and monitoring needs which has worked out rather well ever since.

Why systems banks use an IIS Server instead of an Apache Server over a Tomcat Server(or some servlet container) [...] For what I have seen about online banking systems around here, some of them do use an IIS to do their web hosting (eventually by making use of some internal CMS to actually include/edit content) but the actual banking solution they do use is a J(2)EE application in some app server. In such a scenario, they are required to somehow create an integrated environment (with a behaviour seamless to the user), to somehow linking, say, IIS and the J(2)EE app server / servlet container. I understand the fact that systems uses a Web Server over another to serve static content. But if in my application all content is closed, i.e., every client that wants to accede to that content must be authenticated and that authentication is controlled by Tomcat. There's more to security than just authentication. In our environment, the tomcat installations are on production servers in our LAN fully accessible to our internal users desktop clients (including some more services for document / file access), and external access (from the outside internet) is done via an apache2 reverse proxy living in a DMZ segment. This way, I can keep people from directly accessing my productive systems, which is helpful to say the very least. ;) Cheers, Kristian -- Kristian Rink * http://zimmer428.net * http://flickr.com/photos/z428/ jab: [EMAIL PROTECTED] * icq: 48874445 * fon: ++49 176 2447 2771 One dreaming alone, it will be only a dream; many dreaming together is the beginning of a new reality.

[OT] webdav client libraries for Java?
Folks; sorry for the OT: Being into building a WebDAV enabled application based on tomcat, I am so far trying to find a way how to programmatically interact with the WebDAV using some kind of Java webdav library - but which one? As far as I have seen so far, there is next to no working, up-to-date Java WebDAV client library: - Jakarta Slide seems to have been retired a while ago, the jackrabbit implementation doesn't provide a _generic_ webdav client. - commons-vfs has webdav supported as sandbox component for quite some aeons by now it seems. - SkunkDAV just doesn't work, constantly throwing NPEs, and it's rather old (2001) either. So... does anyone of the kind, wise people out here know a better way how to interact with a WebDAV server from within a Java application? Is there any way how to programmatically access, modify, add, remove files from/to WebDAV without manually crafting a WebDAV client on my own on top of some HTTP client lib?

[OT] applets in webapps
Folks, slightly OT: can someone provide me with a few good pointers and/or hints how to correctly integrate a Java applet into a JEE based web application? More specifically, my problem is something like that: I do have a .jsp containing code to show an applet. Both applet .class and some other resources (.properties files, images, ...) do live inside a .jar file in the same folder as the .jsp. Unfortunately(?), the .jsp is never called directly but rather forward()ed to from within a servlet mapped to some specific URL. So, the situation is that - while calling the .jsp directly (using http://host/context/real-path-to/file.jsp ), the applet loads and runs the way it's supposed to, but - while having the resource called the way it's supposed to (using http://host/context/mapping-for-servlet-forwarding-to-jsp/ ) the plugin doesn't load but provide me with ClassNotFoundException, obviously not capable to find the applet class. Tried playing around with the applets archive / codebase parameters made things just slightly better: By now the browser does lock up, the applet class seems to get loaded, but obviously fails to load some resources, and I see strange access attempts in my tomcat log, trying to fetch resources like /context/servlet-mapping/classpath/lang/de_DE.properties (the file originally lives inside the applet.jar in classpath.lang). Is there any sane way of keeping applets inside a JEE web application, regardless on whether they're invoked directly from a .jsp or from a resource forwarded to from within some servlet? Or am I just too stupid? Sorry again for the OT, feel free to contact me off-list in case you feel like providing me with some hints / pointers.

Let's say the servlet serving up your applet and resources is mapped
to /appletRes in your webapp. The jsp could then access
${request.contextPath}/appletRes/resources/applet.class or what
ever. The client browser would then request the applet/resources
separately and the companion servlet would find
resources/applet.class in your jar file.
Thought about something like that already, as well. However I am unsure
whether it would work out, given that, in our case and looking at what
the applet does, we need to have it digitally signed and packed to
a .jar because of that. Won't using a servlet to provide these
resources from within the .jar file make this sort of providing a
signed applet impossible?
Cheers best regards,

clients behind nat/masq: sessions mixed up?
Folks; dealing with quite an annoying problem right now: One of our web applications (running inside a tomcat 5.5.20 cluster spread across two machines behind an apache2 / mod_jk frontend) seems to act strangely in some situations: Most of the times, the application works rather fine. However, it seems that in some(?) cases when clients working in a LAN connected to the Internet using NAT or Masquerading (i.o.w.: comin' from the same public IP address), their sessions get sort of mixed up, leaving one user seeing the wrong data, suddenly also obviously being authenticated as someone completely else who's working in the application, on a different computer but just within the same network. On one side, this is something rather important to me as providing users access to the wrong data isn't to be considered a good thing. Other side, however, I don't at all know how on earth this could happen - for what I see, the application uses either a cookie (stored on the client side) or a JSESSIONID (also just available on the client side) so having these things mixed up should be virtually impossible... shouldn't it? I am aware that this also might be application-specific. However, does someone of the kind folks around here feel like pointing me some places where to look, here, to get this sorted out?

An easy solution to fix this (at least this is how I do it by now, on several machines) is to set JAVA_HOME and PATH to something like this: export JAVA_HOME=/opt/java export PATH=$JAVA_HOME/bin:$PATH Prepending the $JAVA_HOME/bin to $PATH helps here because, by then, the java(c) commands provided by the JDK are to be found first (and used, by then - otherwise the GNU Java that comes with Ubuntu will be used no matter which JDK you do have installed).

Re: Embed license to tomcat
[Li [EMAIL PROTECTED] @ Fri, 8 Jun 2007 15:29:45 +0800] Our company is going to deploy a system externally. In order to prevent illegal deployment by our customer to other tomcat in case. Why do you want to keep people from deploying your application to another tomcat installation? Do you want to keep them from running pirated versions of your software, or do you rather need the application to be run in a tomcat setup completely configured by and thus (in case of support questions) known to your company? If the latter applies, maybe you'd be better off having a contract stating loss of any warranty and/or support in case the application is run inside a non-certified environment. Surely this is not a _nice_ way to do things but it seems to be a common practise so obviously customers are willing to accept things like that. Otherwise (if you intend to keep people from pirating your software), you possibly should give up on software development and do something else. Trying to protect software from pirates (I hate this term, but that's just my $0.02...) is something software industry has been doing at least for the last two decades, and by now all mechanisms and ideas to do so seems to have completely failed. You won't come up with a reliable software-based solution to keep your customers from running illegal deployments of your software. Period. You might consider asking them to use a hardware dongle solution to at least tie a tomcat/app installation to a given host (don't know whether there are Java interfaces to access these things, but I guess so...). Anyhow, a better way in my opinion would be to give away the software for free (or charging money for it, as you like, but without wasting time / energy on trying to keep people from copying it) and make sure users will get back to you in order to actually _run_ the software. What application are we talking about here? You know, we're a proprietary DMS as an in-house solution... the software itself is not free but rather inexpensive compared to the amount of money you have to spend on adapting the rather generic solution it provides to the very special needs of your business... If this is somehow applicable to your software, I guess it would be the best way...

David kerber schrieb: ... hardware failures won't cause problems. If they move to a completely new machine, but you politely post a nag screen that says something to the effect New hardware detected; please contact Mycompany within 30 days for a new license, then that's not likely to offend many customers. Depends, I guess... Actually, our DMS vendor used to have its licensed coupled to several aspects of the hosts network configuration (MAC, IP address, DNS name), and they dropped this very idea already a bunch of years ago - it's annoying for honest customers, it generates unnecessary maintaineance work, and, most notably, in the age of virtualization it's possibly pointless. We run tomcat nodes that live inside different VMWare ESX (or Virtual Infrastructure as they call it by now...) hosts. No matter what actually happens to the physical hardware - the machines inside are likely to stay the same. You can have the same thing running VMWare Server free of charge on modest x86 hardware and will smoothly make your way 'round any machine-tied licensing mode... You could also have it phone home once a day (or once a week, or whatever) with an app's internal key value, and if you get two connections from the same ID value, then you know there are multiple copies running. No. From a customers point of view, I simply wouldn't deploy such an application, at least not in the enterprise market. Bad enough knowing most desktop software is likely to phone home, the very moment our network monitoring would capture any of these server-based applications establishing unwanted connections to some external site would be end-of-life for this application in our environment. Having an application phone home drastically reduces trust in this very application especially if it is meant to keep track of sensible business information. This IMHO is a way that should be strictly discouraged... just my $0.02 on that...

deployment / war unpacking and Context definition?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Folks, feeling kinda ashamed asking such a (probably rather basic) question, but nevertheless: By now, I only built applications packed to *.war files and then thrown to a tomcat /webapps/ folder, which obviously made / makes tomcat redeploy the application - so far, so good. However, in order to get a JDBC resource set up and running, I added a context definition like this ... Context path=/jdbclink reloadable=true ... Resource name=jdbc/SQLDB auth=Container ... / ... /Context ... and then dumped in a jdbclink.war file. Deployment works fine the very first time, and then never again. :o Even worse, removing the webapps/jdbclink/ folder while the container is running doesn't make tomcat unpack / redeploy the .war file. Likewise, even placing a new war file in webapps and restarting the container doesn't do - I have to stop tomcat and manually remove the unpacked web application in webapps to get the war redeployed again. Haven't messed with any other settings so far, the Host declaration looks like this... Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false We're talking tomcat 5.5.20 atop Ubuntu/JDK 1.6 here. Can anyone enlighten me why in this configuration tomcat doesn't redeploy the application when having a new war file dropped to webapps (by removing the Context definition from server.xml, this does work again...)? It's not all _that_ bad the way it is now, but having to shut down tomcat and manually remove the webapp to get it redeployed is not that fine on a production system running more than just that very application. :) Thanks in advance and bye, Kristian - -- Kristian Rink * http://zimmer428.net * http://flickr.com/photos/z428/ jab: [EMAIL PROTECTED] * icq: 48874445 * fon: ++49 176 2447 2771 One dreaming alone, it will be only a dream; many dreaming together is the beginning of a new reality.

Re: GUI implementation with tomcat
Alicia; [Alicia Sánchez-Mora [EMAIL PROTECTED] @ Thu, 8 Mar 2007 15:05:09 +0100] I have the class Window to initialize the GUI and I call (locally) an instance of this class from my service class. The problem, or at least what I think the problem is, is that every time I make a call the service container unloads my class and nothing (related to my window) is initiallized. The idea is to run my window only one time, when tomcat starts. To do that I should specify somehow on the web.xml file to do this: write a jsp class, put it somewhere and call the initialization of the window.. honestly, the architecture of your overall application by now seems somewhat obscure to me. What exactly do you intend to do? Is the window supposed to display the web service calls actually supposed to be a _desktop application_ window or rather an HTML page rendered by some JSP? If you want to build a GUI, probably you will have to build something like that: * Web Service and related classes deployed to a tomcat application context making use of axis and friends, and * GUI application, built as a standalone Java application making use of Swing(?) to render a GUI and using web service client classes to do remote calls. Can you be more verbose about your application architecture? :) Cheers, Kristian -- Kristian Rink * http://zimmer428.net * http://flickr.com/photos/z428/ jab: [EMAIL PROTECTED] * icq: 48874445 * fon: ++49 176 2447 2771 One dreaming alone, it will be only a dream; many dreaming together is the beginning of a new reality.

Re: GUI implementation with tomcat
Alicia;
first off; thanks for your explanation and pointing things out a little
more. :) I think I slightly understand the structure of your
application but honestly I doubt it will work out this way:
[Alicia Sánchez-Mora [EMAIL PROTECTED] @ Thu, 8 Mar 2007
16:24:33 +0100]
public class ListItems {
List listOptions;
private static ListItems instance;
private Frame f;
This is java.awt.Frame, isn't it?
In my opinion (list people feel free to correct me if I'm all too wrong
here), the issue with your application is that you try to instantiate
and access the java.awt.Frame object from within code running on your
server but you actually want it to appear and work on your client. This
is not going to work out. To do so, you need to have the client code
(containing the Frame stuff) run locally on the client - the fact that
some window does actually appear is likely due to that server and
client runs on the same machine in your setup.
To achieve the desired effect, you should really try separating the web
service and the window connecting to it into two different, separate
applications (a webapp hosting the service, and a desktop application
or an applet running the window/frame). Then, you need to implement
logic in your client to remotely call the web service and possibly get
some meaningful data from it.
Don't know if this really is a helpful answer, feel free to ask if you
need more assistance. :)
Cheers,
Kristian

reasonable session size?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Folks; not sure whether this is too much a tomcat-related question, but at least it relates to Java based web applications so hope someone around here might have an idea on that: While building a Servlet/JSP based intranet application, quite late I realized that somehow just adding new objects / data to the HTTP session, say, is something so easy one makes excessive use once getting acquainted to it. However, thinking about these information being stored somewhere on the server, the idea of performance impacts due to sessions way too large is the next thing to think of. So, to ask: Are there any reasonable maximum sizes for HTTP sessions in general and/or objects attached to a session? What is the maximum session size you would accept before considering rewriting large parts of your application to reduce session size, i.e. by introducing a smarter architecture? Is there any actual use in making _general_ statements here, or is this more likely to be application-dependent and a matter of having server hardware built to meet the needs of the application? What do you think?

tomcat: jmxremote and catalina.sh

Re: clustering and jvmRoute
Rainer; at first, thanks for your hints and getting my view on the world set straight again. ;) [Rainer Jung [EMAIL PROTECTED] @ Fri, 23 Feb 2007 09:32:59 +0100] But: with stickyness (different jvmRoutes and a session sticky load balancer) you only rely on the correctness of the replication when a node actually fails. Since replication takes a little time and is very difficult to implement, that's the better strategy. This seems reasonable. However, in terms of load balancing, I wonder whether there are any benchmark / comparisons on that: - Using stickiness, I ensure each request of a session to run on the host the session initially was started upon. This way, the session is the most fine-grained way I can provide load balancing, but I possibly don't have to spend that much (development, runtime) resources in order to ensure session replication is always correct. - Not using stickiness, and judging from my environment, I see that I can do load balancing on a per-request base, which seems to be a way more fine-grained approach especially in certain imaginary worst-case situations (given that the duration of sessions can drastically vary). But, however, this way indeed I do have to take at least runtime resources for session replication into consideration. Is there a meaningful approach to comparing these setups in terms of worst-case / average-case performance, or is it simply plain trial-and-error (and possibly some lambda-probe watching)?

dynamic JSP include?
Folks; currently I am playing around with something like that in my JSP pages... jsp:include flush=true page=/pages/%= request.getParameter(site)% /jsp:include ... which, as I understand the JSP reference, should be possible. However, it doesn't seem to work right. It actually _does_ work and include the page referred to this way, but it just works _sometimes_, in any other try I get something like this: [...] org.apache.jasper.JasperException: /index.jsp(11,69) equal symbol expected org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:512) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:377) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) [...] (index.jsp line 11 is the full jsp:include as outlined above). I feel sort of stupid now - having something that doesn't at all work would be easier to handle, but the behaviour of this to work once and not work again the next time is rather disturbing. Can anyone enlighten me here? I also played around with the flush but it doesn't really make things better...

Re: dynamic JSP include?
Hi Tim, list;
[Tim Funk [EMAIL PROTECTED] @ Thu, 22 Feb 2007 07:30:23 -0500]
A few problems:
0) Try page='/pages/%= request.getParameter(site)%' (Notice the
use of single quotes - jasper is getting confused by the extra use of
double quotes
This doesn't work, it seems using single quotes keeps jasper from
actually evaluating what's in between them, here.
2) Try validating %= request.getParameter(site)% first in EL so
you can say: page=/pages/${param.site}
That, however, does it. Even though I'm not completely sure to know why
the difference in behaviour, thanks a lot for that hint! :)
Cheers,
Kristian

clustering and jvmRoute
Folks; yesterday I dealt with the tomcat clustering feature for the first time, getting things basically set up and working in quite a short time (thanks to the documentation which is rather good), and even made my application distributable / the session attributes serializable really fast. However, one thing is massively confusing me: I followed the straightforward approach, reading through [1] where there is a configuration file in a section named Simple Engine Cluster Configuration for all hosts - without thinking twice, I installed a configuration similar to that on both of the nodes of my cluster (including the _same_ jvmRoute parameter on both machines) and it worked - no matter which one of the nodes went down, my session remained alive and well. However, spending some more time trying to study the details and options of clustering, I came across [2] and learnt that the jvmRoute parameter should be a per-host not a per-cluster configuration. Thinking twice about this and its implications on session replication, this seems reasonable, and looking at the log of mod_jk while running both tomcats with the same jvmRoute parameter, indeed I see requests belonging to the same session processed by different nodes (which, if I got the servlet specifications right, shouldn't be). So: Why does this setup, having jvmRoute the same in all cluster nodes, work? Just an undesired side-effect of a broken configuration? Luck? Is there something I didn't yet get about the cluster configuration?

This is bad. So, short question, given that modifying the calling

that error? Is that an issue related to the tomcat setup or to axis?

Re: tomcat, apache, mod_rewrite and http-auth
Hi David, @list; On Thu, Aug 17, 2006 at 08:33:21AM -0400, David Smith wrote: Have you tried loosening up the refresh to let's say 5 seconds? Sounds to me like the refresh rate is too intense for a proxy environment. I will give that a try. By now, I started setting up a second configuration using mod_jk which _seems_ to work more reliable using my in-house development environment. Perhaps it will also help providing better external access to the resource. Another way to go (and I don't have the sample code) is to use a little javascript and some AJAX techniques for updating the page without a round trip. Yeah, I thought about this as well, but then again, initially I didn't expect to see any issues with my approach about that, and I am not yet experienced enough to know about AJAX in a proxy environment... Nevertheless, thanks a lot for your hints! :) Cheers best, Kristian -- Kristian Rink * http://zimmer428.net * jab: [EMAIL PROTECTED] icq: 48874445 * fon: ++49 176 2447 2771 Wenn einer allein träumt, ist es nur ein Traum.

tomcat, apache, mod_rewrite and http-auth
Hi all; I do have a web environment running inside my LAN in a tomcat container, forcing users through HTTP Basic authentication. For now and locally, this uses to work well - the browser is prompting the user with a HTTP login window, and everything is fine. Right now, I need to expose this service, and, as for most of the other web sites hosted in our LAN, this includes using an apache2 in a DMZ environment acting as Reverse Proxy using mod_rewrite. So far, so good. My setup is something like that: RewriteEngine On RewriteLogLevel 5 RewriteLog /var/log/apache2/rewrite.log RewriteRule ^/pcd/(.*) http://192.168.1.242:8080/pcd/$1 [P] [L] It works, which I hoped. But it doesn't work _right_. Whenever requesting an URL like http:/domain/pcd/get?... , I am prompted to log in using HTTP auth. But then, after this happened, the browser tries to access 192.168.1.242 instead of domain. This is obviously not working, and this also ain't what I want. But I wonder why mod_rewrite doesn't work well in this situations. Explanations, anyone? Or hints how to get out of this? Much appreciated, if so.

[OT?] Servlet, redirect and progress-monitoring?
Hi all, being aware that this is not a question strictly tomcat-relevant, lacking a really good mailing-list for discussions closer to the J2EE background itself, I hope for some input by all the gurus out there. I'm into a situation like this: A servlet gathers statistical information across the data in our DMS, is supposed to make a PDF out of them and send them back to the client who requested them (PDF is demanded). Problem, however, is that sometimes these computations take quite some time, leaving me with two situations: (a) The browser itself considers the connection to be timed out as the servlet is stuck in doGet() for a bunch of minutes. (b) The user itself considers the connection to be dead and closes the browser window. Both situations are uncomfortable. By now, my initial idea was something like that, utilizing two servlets: - Servlet 1 processes the request and immediately redirects the client to another servlet while finishing the calculations and creating the PDF file. - Servlet 2 refreshes, say, each 2 seconds, checking whether the file in question finally has been created and put in place to, then, send this back to the browser. This, however, doesn't work out as Servlet 1, even though sending the Redirect, doesn't redirect until leaving doGet(). So, that's not the solution... My question, now: Is there any usual / best-practise way of doing something like that, of presenting people with a please-stand-by page while there is activity goin' on in background? Is there a way of solving something like this without being in need of JavaScript/AJAX/DWR or something the like? Any hints, even just pointers to good documentation on that issue, are very much appreciated.

Re: servlet and HTTP authentication
Hey there; and, at first, thanks a lot for the hint. [EMAIL PROTECTED] schrieb: WWW-Authenticate: Basic realm=My Document Management System I'm not sure if tomcat will interpret the resulting Authorization header in the next request, given that you asked him not to authenticate, but you can always ask for the contents of that header, strip off the Basic from the front, and Base64.decode the rest, yielding userid:password. Split on the : and you have your id and password. Hmmm, I feel stupid right now as I could have thought about that myself. Thanks for enlightening me, that's pretty much what I needed! :) Thanks and bye, Kristian -- Kristian Rink * http://zimmer428.net * jab: [EMAIL PROTECTED] icq: 48874445 * fon: ++49 176 2447 2771 Wenn einer allein träumt, ist es nur ein Traum.

servlet and HTTP authentication
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all; gotta solve a very special authentication situation: Users need to have access to certain file packages using an URL like http://.../packages/package-id with package-id referring to an identifier stored in a local document management system. User information (id, password) are stored in the DMS database as well. To provide access to a certain package, I need to ensure (a) the user is valid (thus, has authenticated) (b) the user is owner of the package (which I can find out using the DMS database as well) However, following this approach I cannot use container-based authentication as the DBMS user management repository is not easily accessible via such a configuration but there are Java classes to authenticate the user using an API which to be called from another Java class, a servlet, ... So, my question: Is there a way to configure Tomcat that, for a given servlet or resource, a HTTP authentication window will appear and, then, the data entered there (username, password) is given to the servlet in order to do anything useful with it? I _suppose_ those parameters should be available as part of the Request, but I don't know how to make tomcat demand HTTP authentication _without_ automatically validating these parameters. Any hints on that? TIA and bye, Kristian - -- Kristian Rink * http://zimmer428.net * jab: [EMAIL PROTECTED] icq: 48874445 * fon: ++49 176 2447 2771 Wenn einer allein träumt, ist es nur ein Traum.

css and images (stupid question?)
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all; playing around with tomcat in order to both learn using the package and create a small web site there, I'm currently left with a problem which, though probably being small (and not really related to tomcat), keeps bugging me: I'm trying to do the visual stuff of my jsp using a css style file, which is good, so far. Within the css file, I'm using images for backgrounds etc like that: background: #fff url(/images/bg_header_blau.jpg) no-repeat top left; My problem, right now, is where to put the images within the web application so they're actually found when displaying the page. Initially, I created a folder images within my web application and referred to the images using url(images/...) with relative path names, which didn't work. Also tried to place the images folder inside $CATALINA_HOME/webapps and then using absolute image urls (/image/...), which also didn't work. So, where's the magic? I've always been through some tougher moments with css and images while dynamically generating content, but right now I feel really helpless about that. Can someone enlighten me?

unix user auth within servlets/jsps?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all; another question which probably can be considered stupid, but nevertheless: I'm in an attempt of learning how to deal with server-sided java by rebuilding an intranet solution formerly implemented in Perl which currently runs atop gnu/linux. The java solution I'm about to build is intended to fully replace this, which requires me to do two basic things besides just presenting content: - - users need to be enabled to upload files to some pre-defined folder within the unix filesystem - - users need to have a download page where they can fetch files from within their $HOME - From a Perl programmers point of view, determining which folders to use might be an easy task doing some black text-processing magic using /etc/passwd, but that's somehow not the way, I guess. Besides this, users of course need to login to the site before they may up/download anything, so I need to authenticate them against the Unix-style user information stored locally. I'm not yet completely sure how to deal with this... So, two questions: * How to link a jsp/servlet-based app to any unix-based user management? Will I have to take a dive into JAAS for this, or is there a faster way? * Generally, since this is not really tomcat-related (just to the point that I'm using tomcat for this): Can anyone recommend a good mailing-list for j2ee newbies? :) Thanks for any hints and bye.
