Tomcat9, JSP, CSS and JS not loading in Firefox
Hello,
My question is about loading a JSP page in Firefox (or Google Chrome) and
not having the CSS loaded and the JS operational.
I am using Tomcat v9.0 and Eclipse Java EE IDE v.2019-12 (4.14.0).
When I'm developing using Eclipse IDE, I usually:
- select a JSP in the "WebContent" directory in the Eclipse workspace,
- right-click,
- select "Debug/Run As -> Debug/Run on Server"
and the Webapp starts debugging/running.
With the URL "http ://localhost//.jsp", the page gets
displayed correctly in the Web browser that Eclipse "embeds" (maybe I.E., I
don't know).
In Internet Explorer, the page is displayed correctly too.
Now, if I copy this same URL "http ://localhost//.jsp" in
Firefox or Google Chrome, it's like the CSS is not applied to the page, and
the Javascript code doesn't run when it should.
Note that I didn't use to have that problem before I upgraded Eclipse and
Tomcat (I used Tomcat v.8 before).
Below is the beginning of the JSP page:
--
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http ://java.sun.com/jsp/jstl/core"%>
${initParam['S_IF_MSG_TITLE_WELCOME']}
--
Also in Firefox, I pressed Ctrl + Shift + k and saw the error message:
--
The stylesheet http ://localhost/fr/css/fo.css was not loaded because its
MIME type, “text/html”, is not “text/css”.
--
and the warning:
--
The script from “http ://localhost/fr/js/fo.js” was loaded even though its
MIME type (“text/html”) is not a valid JavaScript MIME type.
--
Can you help me solve that problem?
Best regards.
--
Léa
P.S. I added a space after each occurrence of the pattern "http" in this
message.

Is it the case ? Thank you for your answer. No, it is not the case. - There are no .class files from project3 under classes directories for the two projects project1 and project2. - I didn't make a .jar file out of project3 because I don't want to have to do it every time I change the code of the classes in project3... Note - If I do not add project3 via Project - Properties - Java Build Path - Projects for both projects project1 and project2 I get hundreds of errors. So clearly this is a required setting... I don't know what is missing... Thank you for helping me. Best regards. -- Léa In Eclipse, try Project / Properties / Deployment Assembly. Add project 'project3'. It should add project3's resulting jar file to WEB-INF/lib or resulting classes to WEB-INF/classes depending on how project3 is configured. UPDATE: The 2nd part of that sentence is not true; it will always add the resulting jar file of project3. However, it will create jar file on the fly when the webapp is re/deployed OR when project3 is modified. Keep in mind that this is simply a quick dirty way of testing the app from within Eclipse and NOT suitable for building a deployable war file. You should use Maven or Ant or etc. for that. Ok.

Thank you for your answer. Konstantin Kolinko wrote: Deployment can be done from Ant or from Maven. There exists tools for that. Ok, I understand. Konstantin Kolinko wrote: If you are developing your web application, is there a reason why you run Tomcat standalone and not from within Eclipse IDE? Here is why. On a Unix machine, I start Tomcat as a service, as a non-root user and via JSVC. (This is the as a non-root user part which is important here for me). Below is what I tried. First test: - remove /etc/init.d/tomcat7 from /etc/init.d/ and reboot the machine so that Tomcat is not automatically started at all (and so that I'm sure no other process is using the TCP ports 80 and 443) ; - run Eclipse as a non-root user ; - add a local Tomcat server to the Eclipse workspace ; - run a JSP on the server. = I get the error message: Several ports (443, 80) required by Tomcat v7.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s). Second test: - run Eclipse as root ; - run a JSP on the server. = There is no error message anymore. BUT, I need to run Tomcat as a non-root user. In particular, I need it for subsequent operations made via the webapps deployed on the Tomcat server (for example: directories and files creations). This is the reason why I wanted to use the standalone Tomcat that is started via the /etc/init.d/tomcat7 script. Usually, on my Windows development machine, I do not have these kind of issues. This is why I normally and usually use the Tomcat running on the Eclipse JVM. Does it make any sense? I wonder how people developing daily on a Unix machine do to debug their webapps in Eclipse as a non-root user. Maybe you do? I would totally be glad to know what is the usual practice.

Thank you for your answer. Konstantin Kolinko wrote: Why do you need the ports to be 80 and 443? (You cannot open those on Linux unless you are a root). You can a) change the port numbers in your configuration b) use firewall (iptables) to map different local ports to those external ones https://wiki.apache.org/tomcat/HowTo#How_to_run_Tomcat_without_root_privileges.3F Well, apparently, according to the author of this article, I chose the best method (JSVC)! But thank you very much for pointing me towards this article and this FAQ which looks very interesting, full of interesting questions (and answers). Indeed the iptables solution looks attracting. I chose JSVC because I wanted Tomcat to be started at boot time and, if I'm not mistaken, this is root who runs the /etc/init.d/ scripts including the /etc/init.d/tomcat7 script... but I needed Tomcat to be run as a non-root user etc. etc. Konstantin Kolinko wrote: Also, https://wiki.apache.org/tomcat/FAQ/Linux_Unix#Q5 That's exactly what I did and I did it for exactly the same reasons given in this article.

Thank you for your answers. @MarkEggers Thank you very much for sharing. Christopher Schultz wrote There are reasons to use jsvc, but the ability to run as a non-root uses is not one of them. What are these reasons according to you (apart from running Tomcat as a daemon on Unix which was also one of my goals at the time)? Also Excerpt from here: http://tomcat.apache.org/tomcat-7.0-doc/setup.html#Unix_daemon jsvc has other useful parameters, such as -user which causes it to switch to another user after the daemon initialization is complete. This allows, for example, running Tomcat as a non privileged user while still being able to use privileged ports. Thanks.

Debugging a Webapp in Eclipse running Tomcat as a stand-alone JVM process
Hello and thank you for reading my post. My problem is about debugging a Webapp in Eclipse running Tomcat as a stand-alone JVM process. -- In more details -- Below is what I would like to do: - Start Tomcat: - on Windows: via startup.bat in a cmd.exe ; - on Unix (Debian Squeeze): via JSVC in a /etc/init.d/tomcat7 script. - Run Eclipse (Juno): as a non-root user (say U). - Debug a Webapp in Eclipse running Tomcat as a stand-alone JVM process (NOT running Tomcat from within the Eclipse JVM). This article states that it is possible to do this: http://blogs.mulesoft.org/debugging-your-tomcat-webapp-with-eclipse/ Excerpt: Once you have Tomcat running successfully as a separate process, and your webapp happily running on it, you can begin configuring remote debugging. A) First of all, I do not manage to: have Tomcat run successfully as a separate process, and your webapp happily running on it [in Eclipse (personal addition)]. Can you tell me what I have to do? (I hope it doesn't mean putting a .war file in the Tomcat webapps directory because I know how to do that already). B) Second of all. As for the debugging part, below is what I did so far: 1) In startup.bat, I added the two lines: set JPDA_ADDRESS=8000 set JPDA_TRANSPORT=dt_socket I modified the line: call %EXECUTABLE% jpda start %CMD_LINE_ARGS% Below is the startup.bat that I have presently: -- @echo off rem --- rem Start script for the CATALINA Server rem --- setlocal rem Guess CATALINA_HOME if not defined set CURRENT_DIR=%cd% if not %CATALINA_HOME% == goto gotHome set CATALINA_HOME=%CURRENT_DIR% if exist %CATALINA_HOME%\bin\catalina.bat goto okHome cd .. set CATALINA_HOME=%cd% cd %CURRENT_DIR% :gotHome if exist %CATALINA_HOME%\bin\catalina.bat goto okHome echo The CATALINA_HOME environment variable is not defined correctly echo This environment variable is needed to run this program goto end :okHome set JPDA_ADDRESS=8000 set JPDA_TRANSPORT=dt_socket set EXECUTABLE=%CATALINA_HOME%\bin\catalina.bat rem Check that target executable exists if exist %EXECUTABLE% goto okExec echo Cannot find %EXECUTABLE% echo This file is needed to run this program goto end :okExec rem Get remaining unshifted command line arguments and save them in the set CMD_LINE_ARGS= :setArgs if %1== goto doneSetArgs set CMD_LINE_ARGS=%CMD_LINE_ARGS% %1 shift goto setArgs :doneSetArgs call %EXECUTABLE% jpda start %CMD_LINE_ARGS% :end -- 2) In Eclipse, I went to the menu Run - Debug Configurations... - Remote Java Application I entered the following values: -- Name: ExternalTomcat Project: webapp_pjt1 Connection type: Standard (Socket Attach) Host: localhost Port: 8000 -- I clicked the buttons Apply and then Debug. 3) I set a breakpoint somewhere relevant in the Webapp code. 4) I tried to send an HTTP request to the Tomcat server: I entered https://localhost/webapp_pjt1/welcome.jsp in a browser (NOT the Eclipse internal browser). I got a HTTP 404 error. Can you see what I'm doing wrong?

Re: From HTTP to HTTPS request.getHeader(referer)
Hello and thank you for your answers. I would like to say that my problem is solved (even though I would like to answer the remarks you made). I can't really tell what combination of adjustments (see my previous posts) are responsible for it. I just did things with more care than when I do things hastily (or just to try something). I'm saying this because (see below) I thought sendRedirect() was working only if I passed it the complete HTTPS URL of the JSP I was willing to redirect to user towards. I appears that now, it works if I only pass the JSP page name to sendRedirect() (like I did in the past when dealing with HTTP requests only). So, I don't really know what to think :'/ Christopher Schultz wrote: If you are already in HTTPS protocol and don't want to switch, then you shouldn't have to specify the protocol in the redirect. Well, indeed, it looks like I don't have to specify the protocol anymore... (see my comment above). Christopher Schultz wrote: Yes, they don't really help in any way because they don't describe use cases. You didn't provide anything like I want X, I tried Y, and Z happened so it's hard to help you out. Well, it troubles me because, I was willing to give you some relevant information (I just often do not know which and I also understand it's not easy for you to understand my stuff when you only get pieces of it). I wanted to know if my HTTPS configuration for a standalone Tomcat serving all the pages of some webapps with the HTTPS protocol is fine or not. The configuration details I sent previously are really the only thing I do (to have Tomcat serve the webapps JSPs with the HTTPS protocol)... Normally, if I'm not mistaken, I can switch back to HTTP by: 1) Removing the security-constraint element from the webapp web.xml file. 2) Replacing the three connectors: Connector port=quot;443quot; [...] lt;Connector port=quot;80quot; [...] lt;Connector port=quot;8009quot; [...] from the Tomcat quot;server.xmlquot; file (see the post in which I posted the config) and replace them with the two connectors: lt;Connector port=quot;80quot; protocol=quot;HTTP/1.1quot; connectionTimeout=quot;2quot; redirectPort=quot;8443quot; / Connector port=8009 protocol=AJP/1.3 redirectPort=8443 / To try to give you an answer: this is probably a typical use case in the webapp: - The user has requested a JSP page x.jsp: it can see this page properly in its browser. - The user submits this JSP's form (which has an action attribute mapped with a servlet in web.xml). - The doPost() method of the servlet is invoked. - Some instructions are executed (database access for example). - Before exiting (return;) the doPost(), I execute response.sendRedirect(y.jsp). This used to fail before: I don't remember the error but the page y.jsp wasn't served at all. This is working now. I thought that the two things I configure (1. security-constraint element the web.xml of the webapp and 2. the connectors Tomcat server.xml) are just enough to show what I do to make Tomcat serve the the JSPs of some webapps with the HTTPS protocol... If this config looks good and if what I wrote just now doesn't bring anything new to the table, please ignore it since its working now. Christopher Schultz wrote: Look at your access log to file out what's going on when you request an http:// URL.

Just reading this, can someone (you for instance) infer that the page welcome.jsp was served using the HTTPS protocol? Is there another log file where this can be checked?

Re: From HTTP to HTTPS request.getHeader(referer)
Hi, Christopher Schultz wrote: If you want to switch protocols I don't think I want that... but maybe I do not understand properly what you mean... For the webapp I've been considering in that thread, I would like Tomcat to serve pages only via HTTPS. I do not want some pages to be served via HTTP and some others to be served via HTTPS. I don't know if it clarifies my point... Have you had a little time to have a look at the configuration files I posted yesterday (complete server.xml and excerpt from the webapp's web.xml)? 1) In web.xml, I set the CONFIDENTIAL security constraint which, as far as I understood, imposes the use of the HTTPS protocol to serve the JSP pages of the webapp. 2) Ideally, I would like the webapp users to enter HTTPS URLs in their browser URL bar/directly click URLs like https://host/webapp/a-page.jsp. But I also would like them to be able to enter HTTP URLs like http://host/webapp/a-page.jsp which are, to my understanding automatically transformed into https://host/webapp/a-page.jsp thanks to the server.xml configuration line: Connector port=80 enableLookups=false redirectPort=443/ I realize I do not know what happens to the request in that case (http://host/webapp/a-page.jsp). Is it encoded or not? Terence M. Bandoian wrote: I'm not sure how you're using it but it's worth pointing out that response.sendRedirect Sends a temporary redirect response to the client... The client (browser) must then send another request to the server before any additional processing takes place. In contrast, pageContext.forward takes place entirely on the server. I didn't know that. I thought there was one HTTP(S) request and one HTTP(S) response only. How can the mechanism you describe above affect the use of HTTPS for a webapp with the CONFIDENTIAL security constraint on a standalone Tomcat server? I'm using sendRedirect() in a very straightforward way I think. I use some sort of pipelines for a subset S of JSPs in the webapp: 1) Given a JSP s in S, it contains a form with an action attribute mapped via web.xml to a servlet L. 2) The servlet L implements either a doPost() or (rarely) a doGet() method. 3) Given what was submitted via the form, work is performed in the servlet. 4) When the servlet work is done and depending on the result (success 1, ..., success n / error 1, ..., error n), the servlet redirects towards the next JSP using the method sendRedirect(). Is there a temporary redirect response to the client in that case? Is this behavior documented somewhere? I could totally benefit from a good documentation...

Put your code back the way you had it, take more data, and post a new question if you need help. Ok. Thank you. I restored the sendRedirect() calls I was making at first. I proceeded like I described in my last post: passing complete URLs to the sendRedirect() methods (ex. sendRedirect(https://host/webapp/example.jsp;);). As a reminder, before, I used to pass only the JSP page name as an argument to the sendRedirect() method (ex. sendRedirect(example.jsp);). It looks like that the webapp is now working nicely. I noticed your comment about encodeRedirectURL(). Thanks for mentioning it. When you use a forward, you will always end up with the URL the client first used as what the client sees. If you want to accept data (e.g. POST) *and* prepare some data for the next screen to be seen, consider a POST-then-redirect scheme: 1. Client POSTs to some URL e.g. /do_example 2. /do_example servlet runs and handles the POST data, then redirect()s to /prepare_view 3. /prepare_view servlet runs and gathers whatever data is appropriate for the next display screen and forward()s to /example1.jsp After all that, the user is looking at the URL /prepare_view instead of /do_example. That way, your referrer for the next POST will be /prepare_view instead of /do_example. Thank you. It's interesting. What if the user hits the BACK button and looks at a previous page, then re-submits that old page? Your server thinks that the source page was example1.jsp but the client actually posted example0.jsp or something else... Web application workflow management is non-trivial. Yes, it's tricky. Best
Re: From HTTP to HTTPS request.getHeader(referer)
Hello Mark, Chris and Terence. Thank you for your answers. After reading them and observing a few things I realized that my problem is not exactly the one I described at first. Christopher Schultz-2 wrote The Referer is going to be the URL that was showing in the web browser when the user clicked on the Submit button. This is right. I hadn't noticed it but the URL which is showing is NOT https://host/webapp/example1.jsp. Instead, it is https://host/webapp/do_example. So, what I was describing as abnormal in my first post is actually normal. So the problem is coming from elsewhere... Before I tried to make the webapp work with HTTPS, I was always using calls like these: -- response.sendRedirect(example1.jsp); -- Last week, I replaced all these calls with these new ones: -- requestDispatcher = getServletContext().getRequestDispatcher(/example1.jsp); requestDispatcher.forward(request, response); -- (with the appropriate JSP of course). I made that change because sendRedirect() didn't work with HTTPS. I didn't mention this before because I thought it was solving this other problem. Instead, it provokes new ones. What I actually would like is the webapp to behave like before: showing JSP page names in the URLs bar instead of URL patterns: in a given servlet, I generally have several forward() calls and hence several different .jsp pages to forward to depending on what happens inside the servlet. Having all of them replaced by something like do_example is kind of not what I had planned. It's definitely very problematic. So, hum, as I didn't asked it at the time: why can't I go on using sendRedirect() along with HTTPS? If I have to use forward(), is there any way I could make it behave the way I described above? Is there another method I could use that would suit my needs? Best regards. P.S. For the problem I was posting at first, as I don't really need to rely on the referer request header, I can instead, set a session attribute in each JSP.

From HTTP to HTTPS request.getHeader(referer)
Hello and thank you for reading my post.
I'm trying to make a webapp work with HTTPS.
It was working properly with HTTP.
Below is the problem I have.
Inside a servlet, in its doPost() method,
to check whether the incoming JSP is example1.jsp or example2.jsp,
I am using the following piece of code:
---
s_referer = request.getHeader(referer);
if(s_referer.contains(example1.jsp) == true)
{
b_jspReferer1 = true;
}
if(s_referer.contains(example2.jsp) == true)
{
b_jspReferer2 = true;
}
---
In example1.jsp and example2.jsp there is a form element
which action attribute is set to do_example:
---
form method=post action=do_example
[...]
/form
---
Now that I'm using HTTPS, s_referer is always equal to do_example in the
servlet.
Before, it used to be either example1.jsp in case the incoming JSP was
example1.jsp
and example2.jsp in case the incoming JSP was example2.jsp.
I don't know how to correct my code to be able to discriminate between the
two JSPs.
Can you please help me?
I apologize in advance for the barbaric expression incoming JSP.
I hope my point is understandable despite unfortunate expression.
Best regards.

HTTPS / URLs with no port number / Tomcat only
Hello and thank you for reading my post. I was willing to run only a Tomcat server and not a Tomcat server + an Apache HTTP server. Mostly because: - an article like this one: http://www.tomcatexpert.com/blog/2011/11/02/best-practices-securing-apache-tomcat-7 says, if I understand properly, that Tomcat is secure enough with what it basically implements, - and because, if possible, I don't want to have to secure an Apache HTTP server in addition to the rest of the architecture... (Actually I already made a solution work with an Apache server but I was wondering if I could do without it). So, I am willing to serve HTTPS pages only with Tomcat and with URLs not including a port number. I did some config (mostly taken from http://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html and http://java.dzone.com/articles/setting-ssl-tomcat-5-minutes) I could make this work: https://localhost:8443/my_webapp/a_page.jsp And this: http://localhost/my_webapp/a_page.jsp automatically redirects to: https://localhost:8443/my_webapp/a_page.jsp Now, in all possible cases, I would like to have this URL instead: https://localhost/my_webapp/a_page.jsp (which doesn't work presently). Can this be achieved with Tomcat ONLY? And how?

Re: How can Tomcat be started at boot time as a non-root user
Hello Dan and thank you for your answer. I installed the JSVC tool as indicated in your document http://tomcat.apache.org/tomcat-7.0-doc/setup.html#Unix_daemon I copied the jsvc executable into /opt/tomcat7/bin/.

File download using a servlet and error handling
Hello and thank you for reading my post.
My question is about downloading a file using a servlet and handling
possible errors that may take place during the download process.
1) I have a JSP page download-file.jsp with a Download file button:
==
form method=post action=do_download_file
[...]
input type=submit name=download_file id=download_file
value=Download file /
[...]
/form
==
When this button is hit by a user, the doPost() method of the servlet
mapped with the action do_download_file is executed.
It includes a call to the method below.
2) Everywhere on the Web one can find that type of code (for the file
downloading):
==
public boolean downloadFile(String s_fileNameAndPath, String s_fileName,
HttpServletResponse httpServletResponse)
throws IOException, SQLException, ClassNotFoundException, ModelException
{
File file = null;
long l_fileLength = -1;
ServletOutputStream servletOutputStream = null;
int n_bufsize = 4096;
DataInputStream dataInputStream = null;
int n_nbBytesRead = -1;
boolean b_anErrorOccurred = false;
byte[] byteBuffer;
file = new File(s_fileNameAndPath);
l_fileLength = file.length();
if(l_fileLength = 0)
{
b_anErrorOccurred = true;
return b_anErrorOccurred;
}
n_nbBytesRead = 0;
byteBuffer = new byte[n_bufsize];
servletOutputStream = httpServletResponse.getOutputStream();
httpServletResponse.setContentType(text/html);
httpServletResponse.setContentLength((int) l_fileLength);
httpServletResponse.setHeader(Content-Disposition,
attachment;
filename=\ + s_fileName + \);
dataInputStream = new DataInputStream(new
FileInputStream(file));
while((dataInputStream != null)
((n_nbBytesRead = dataInputStream.read(byteBuffer))
!= -1))
{
servletOutputStream.write(byteBuffer, 0,
n_nbBytesRead);
servletOutputStream.flush();
}
if(true)
{
throw new ModelException(To provoke an error
on purpose.);
}
dataInputStream.close();
servletOutputStream.close();
return b_anErrorOccurred;
}
==
(Apart from the exception being thrown) this code works: it actually
downloads the targeted file.
You may have noticed that in the method above, I deliberately throw an
exception so that I can test error handling.
My problem is that, with this way of doing things, I can't tell the user
that the download operation failed since the HttpServletResponse has
already been consumed when the method returns...
My question is:
Ideally, after the download, I wish I could go back to the JSP
download-file.jsp so that I can tell the user that an error occurred while
downloading the file.
If the download was successful, I also would like to tell the user that
everything went right...
I don't see how I can both download the file and redirect the user towards
the download-file.jsp page with an appropriate message.
Do you have an idea how I should proceed?
All the best and sorry for the language approximations like consumed, etc.

Lots of configuration descriptors
Hello and thank you for reading my post. My question is about configuration descriptors and how Tomcat deals with a lot of them. I have been thinking about a solution for a problem I have to solve. This solution would involve the creation of possibly a lot of configuration descriptors. -- About configuration descriptors (just to make sure we are talking about the same thing) -- (In my case) the configuration descriptors are XML files which contain only one XML context element. They are very simple. For example: Name --- webapp#confdescr1.xml Contents --- Context docBase=/somewhere/on/the/filesystem / Location --- webapp#confdescr1.xml is put in /etc/tomcat6/Catalina/localhost/ Then, suppose that there is a file my_file.txt in the directory /somewhere/on/the/filesystem/, Tomcat can serve it via the URL http: //localhost/webapp/confdescr1/my_file.txt. -- My questions are: -- Is Tomcat going to behave nicely (that is to say answer quick enough) if it has hundreds (even thousands) of configuration descriptors to deal with? If a user wants to download the file http: //localhost/webapp/confdescr1/my_file.txt, is it going to have to wait a long time while Tomcat is looking for the configuration descriptor webapp#confdescr1.xml to be able to serve the file my_file.txt stored in /somewhere/on/the/filesystem/? Does Tomcat implement a mechanism to find a configuration descriptor quickly, like an index? I hope my question is clear enough.

Hello Casper, Thank you for your answer. What you are explaining totally makes sense.

André Warnier wrote Presumably, it is via a POST, to a servlet you have created. That servlet knows where to store the files that are uploaded, via some parameter which it reads somewhere. Yes. André Warnier wrote Christoper's (and my own) suggestion is to create a similar servlet that serves to download the files, and which would use the same parameter to know where to download them from. Again, it looks very interesting. Maybe it's what I've been looking for from the beginning. To @André Warnier: Thank you for the two references Automatic Application Deployment and Single Sign On. If any of you two can post the code of the file-fetching servlet, it would be great.

Re: Tomcat6 - Context - aliases
@André Warnier: Thank you for your detailed answer. As of your objections: 1) We don't agree with each other. I *DO* care about what URLs look like: a) in general, b) for some reasons related to the user's speaking language, c) for search engines, d) ... The URL of a link can be seen in many circumstances and is used in various ways both by humans and bots. 2) I want the resources (files and other things like databases) to be stored outside the servlets container and more precisely on another partition, especially if data get erased when the context which contains them is undeployed! André Warnier wrote Do you know that when a Context is undeployed by Tomcat, all its files are deleted ? This is certainly not what I want. I would expect Tomcat to provide a mechanism for it not to happen. (See my questions at the end of this post). André Warnier wrote with your method consisting of creating a new context on-the-fly Am I? I put an_alias_1.xml in /etc/tomcat6/Catalina/localhost/ once and only once (never touch it again afterwards). André Warnier wrote But this is a logical consequence of building a context from scratch, outside of you /w context, and having Tomcat serve it, without any kind of security protecting that location. It's not exactly my full responsibility. I'm looking for a solution, remember. I'm not especially keen on that solution. André Warnier wrote An undeploy of a Context does not generally happen by itself What is the probability of such an event occurring? If it's like a rm -R on the directory, I'll forget about it. So, given your thoughtful observations, here are my questions: 1) Can you tell me how to test a context undeployment in command line (not via Tomcat Manager please)? 2) Is there any way, I can prevent a context to be undeployed ever (like setting a specific option in a configuration file, in an_alias_1.xml for example)? 3) Is there any good example illustrating how to do a cross context authentication you can point me to?

Re: Tomcat6 - Context - aliases
Hello André, André Warnier wrote - you need to tell your webapp where the uploaded files should be stored/retrieved - you cannot do it via an alias under Tomcat v7 Exactly. André Warnier wrote - so instead of an alias, do it via a property in a properties file, which your webapp would read. This is (almost) a pure java solution, which would work under any servlet container of any version. I wish I knew how to do that and yes, I'm interested in an (almost) pure Java solution. May I precise what I did and what already works with Tomcat7: 1) When a user uploads a file to the server running Tomcat, I store the file, for example, in a directory: /home/d1/ 2) In a JSP, this user can view the list of the n files he uploaded: -- a href=/an_alias_1/file_1.txt file_1.txt /a ... a href=/an_alias_1/file_n.txt file_n.txt /a -- 3) In Tomcat7, I used the aliases properties of the Context element in META-INF/context.xml to (magically to me :/), let Tomcat map these addresses: -- /an_alias_1/file_1.txt ... /an_alias_1/file_n.txt -- to their real addresses on the filesystem: -- /home/d1/file_1.txt ... /home/d1/file_n.txt -- so that the user could click on one of these links and retrieve/view the corresponding resource. Of course, I read carefully what you wrote, it looks like I'm really missing something important because I have absolutely no idea how to implement the same mechanism using a properties file as you suggest... Would you be so very kind to to explain a bit more?

Re: Tomcat6 - Context - aliases
Ok. So, I found a solution, if I can call that a solution. - I created a file an_alias_1.xml in /etc/tomcat6/Catalina/localhost/ (the OS being Debian Squeeze). - Here are the contents of this an_alias_1.xml file: Context path=/an_alias_1 docBase=/home/d1 crossContext=true / - This Configuration Descriptor is automatically deployed once saved. - I suppressed the Webapp w's WEB-INF\context.xml I had created. - I redeployed the Webapp w. = Now, when a user clicks on any link a href=/an_alias_1/file_ i.txt file_ i.txt /a it is successfully retrieved. = What is still problematic to me, is that, when the user clicks on a link, the context or Webapp changes (from w to an_alias_1). The resources which are in /home/d1 are available directly by typing the following URL in a browser: http://hostname:8080/an_alias_1/file_ i.txt and not compulsorily through the Webapp w.

Tomcat6 - Context - aliases
Hello, I've been struggling lately with the aliases attribute of the Context element of the context.xml file. I tested a Webapp with Tomcat7 and it appears to work properly. As a Debian user, Tomcat7 is not yet packaged in the current stable release Squeeze so I installed Tomcat6 instead. Result: the Webapp no longer works properly (as far as the aliases attribute is concerned). When I have a look at the Tomcat6 documentation (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), it looks like the Context element aliases attribute is not available. 1) Can you confirm it is not? 2) How can I workaround this problem?

Once copied, Tomcat6 refers the one in TOMCAT_HOME/conf. Tomcat7.0.26 no longer copies context.xml. I placed context.xml in yourwebapp/META-INF/. I am aware of what you mentionned above.

Thank you for your answer.

No, you are right.
What I meant is that I was/am managing session expiration inside the Webapp
(for instance if the user clicks a button which is inside the Webapp and if
the session has expired, I redirect him to the log in page).
Christopher wrote:
I always try to have enough information in the page (form) so that

I'm sorry but I do not understand what you are explaining me here...
A SOLUTION... I THINK.
I have found a solution, here it is:
for all the JSPs which require a user to be identified (*), I add the
following code:
%
ASessionAttribute aSessionAttribute = null;
HttpSession httpSession = null;
httpSession = request.getSession();
aSessionAttribute = (ASessionAttribute)
httpSession.getAttribute(aSessionAttribute);
if(aSessionAttribute == null)
{
response.sendRedirect(the-log-in-page.jsp);
}
%
Then if a user presses the F5 key and if the session has expired, he is
properly redirected to the log in page.
Best regards,

Léa
(*) That is to say, in my example, the aSessionAttribute object musn't be
null.

Re: WebApps sharing uploaded files
Hello. Ok. I found what I was doing wrong and corrected my mistake: added /w1 at the beginning of the href attribute value. See below: 2.C) test_download.html html head titleTest download/title /head body /w1/attachments/foo.txt Foo.txt /body /html Now it works!

Re: WebApps sharing uploaded files
Hello André, Do you mean that you are going to create a new JSP for every new file someone may ever upload? No... Or do they always upload the same file f.txt? No... I understand your being puzzled... my bad: the example I posted is oversimple but it works if tested! In reality, the c:choose is dynamic in the JSPs: it is part of a loop which loops through a dynamic list of attachments. And yes you're right, contrary to my original description, there is not a unique uf directory storing both the attachments of w1 and those of w2. Some attachments are in w1\uf1, all the others are in w2\uf2 (it's a partition). That solution is quite good because: - there are no file duplicates, - the JSPs are the same, - I just need a switch inside of them to pick the attachments in the right directory according to a test. What's interesting is that, in the same servlets container, one WebApp has access to another WebApp through /w1/uf1/f.txt /w2/uf2/f.txt type of addressing.

Re: WebApps sharing uploaded files
Hello, I solved my problem: 1) in WebApp w1, upload files to the directory w1\uf1\, 2) in WebApp w2, upload files to the directory w1\uf2\, 3) then you can have the same JSP foo.jsp for both WebApps. Put one JSP in w1 and another one in w2. The JSP itself contains a switch: c:choose c:when test=a_test a href=/w1/uf1/f.txtLink 1/ a /c:when c:otherwise a href=/w2/uf2/f.txtLink 2/ a /c:otherwise /c:choose Best regards, -- Léa -- View this message in context: http://old.nabble.com/WebApps-sharing-uploaded-files-tp32570911p32583746.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: WebApps sharing uploaded files
Hello Tim, Ok. - I have only one copy of f.txt. - uf1 and uf2 are two distinct directories, the first in w1, the second in w2. - I have one JSP (same code) but two copies of it, the first in w1, the second in w2. f.txt either lives under uf1 xor uf2. Maybe I'm not clear enough... but that's basically what I was trying to do...

Re: WebApps sharing uploaded files
Hello André, Thank you for your answer. awarnier wrote: You can define uf wherever you want, as long as Tomcat (and the applications which run under it, like your JSPs) has write access to it. Actually, I already noticed and tried that and my first question is closely linked to my second question about hrefs... (Questions 1) and 2) aren't really two separate questions.) Thank you for your two interesting suggestions: - creating some kind of downloader servlet, - WebDAV which I know nothing about. This is not an academic project. I just made a schematic picture of the situation.

WebApps sharing uploaded files
Hello, Thank you for reading my post. o I have two WebApps w1 and w2 (under the Tomcat webapps directory). o Both w1 and w2 contain (at least) a JSP which allows to upload files to the server. o Presently, the uploaded files are stored: - in the w1\uf1\ directory for w1, - in the w2\uf2\ directory for w2. (So: each WebApp has its own directory for uploaded files storage). = I need the two Webapps to store their uploaded files in the same directory, say uf. Let's say that: - we have created uf somewhere (where?), - uf contains a successfully uploaded file f.txt, - I have a JSP foo_1.jsp in w1 and a JSP foo_2.jsp in w2. I'd like: - to put an anchor in foo_1.jsp which links to f.txt. -- a href=?_1/f.txtLink 1/ a -- - to put an anchor in foo_2.jsp which links to f.txt. -- a href=?_2/f.txtLink 2/ a -- (I want the files to open properly when the each link is clicked). 1) If it's possible, where shall I create uf? 2) What shall I replace ?_1 and the ?_2 with in the href anchor properties? Please help me.
