Problem with tomcat behind IIS and modjk using integrated windows authentication
Hello, I developed a webapplication with tomcat 6.0.14 behind IIS 6 (IIS5 isolation mode) using modJK (1.2.25) and integrated wíndows authentication. I configured IIS and modJK following the descriptions in the connectors documentation. For most of the users (~70%) it works without problems. The rest always gets service unavailable from IIS. Other ASP Applications which are using integrated windows authentication work for the affected users. I looked in the log files of IIS and modJK and found nothing. I think it must have something to do with the windows profile because when we delete the windows profile of the user (c:\Documents and Settings\user) and recreate it then all works well for this user. We don't no why this happens, we can't see a difference between working profiles and not working ones e.g. the IE settings are the same. The problem is we can not kill and recreate all the profiles of the affected users.

Problem serializing JDK dynamic proxies
Hi all,
I am using Tomcat 6, and running in a cluster, with session-replication.
When I put in the session a JDK dynamic proxy, the serialization fails, like

Re: How can I refresh tomcat in the java code?
.
Hi Guilherme
I can see that English isn't your first language and I have a lot of
respect for anyone who is trying to work on technical things in a
foreign language - I could never do it!
To help our communication I have tried to explain below what I think it
is that you are trying to do. I may have misunderstood what it is that
you are doing so I apologize if what I am saying is wrong.
I've joined this thread a bit late, but looking at the previous emails
it seems to me that your need is that a user should be able to download
a pdf file which has been generated by your server?
This is 'dynamic content'. The server responds to the request for a file
by creating an OutputStream of pdf data
Your use case is that the user clicks on a link in a web page and the
PDF file appears in their browser?
Here's what I would expect the sequence of events to be:
1. The user clicks on the link in the browser. The link has as its href
for example www.mycompany/xyz.pdf
2. The browser generates an http GET request with the url
www,mycompany/xzy.pdf and sends it out over the net.
3. Your container detects this request, looks up the appropriate servlet
in its web.xml and calls the HttpServlet 'doGet' method.
4. Your servlet responds to this request and generates the pdf in a
temporary file.
5. You set any response headers that you need to set.
6. You read the temporary file as a byte InputStream and write this to
the servlet OutputStream.
7. The container takes the data from the output stream and transmits
across the wire back to the browser. It inserts any headers you have
specified (and a few others) at the beginning.
8. You return from the doGet.
That's it. Done!
So the stream of data which is returned as the response to .../xyz.pdf
IS the data you want displayed. You don't need to send a redirect to
xyz.pdf because you have already responded to the request.
The exact point at which the container (Tomcat) starts to transmit data
is up to the container. You can force it to send data by issuing a
'flush'. However, once it has started to respond to the specific request
you cannot issue things like a redirect. I'm simplifying a bit here.
Looking at your code there doesn't appear to be the doGet method - I
assumed initially that you were calling your class from within the doGet
of a servlet. Is this the case?
Have you checked the tomcat logs? I would have expected the server to
have thrown an exception when you attempted to send a redirect after you
have already written data.

These good folks are telling you to do something differently than you
are currently doing it.
Right now you are trying to:
1. generate your content
2. write the content to a file on the disk
3. redirect the user to the newly-generated file on disk
Everyone is telling you to:
1. generate your content
2. write the content out to the ServletOutputStream directly
~ (not to System.out, nor to a FileOutputStream)
No disk file; no redirect. Each request re-generates the content and
sends it back to the client (browser) as the response to the original
request.
Let me lay it out for you. You currently have this code:
| try{
| ServletOutputStream sos = response.getOutputStream();
| pdfStream.writeTo(sos);
| System.out.println(pdsStream - +pdfStream);
| response.sendRedirect(myPDF.pdf);
| sos.flush();
| sos.close();
| pdfStream.close();
| pdfStream = null;
| }catch(IOException e){
| e.printStackTrace();
| }
| return ;
You should change it to:
try{
~ServletOutputStream sos = response.getOutputStream();
~pdfStream.writeTo(sos);
~sos.flush();
~sos.close();
~pdfStream.close();
} catch(IOException e) {
~e.printStackTrace();
~response.sendError(HttpServletResponse.INTERNAL_SERVER_ERROR,
~ e.getMessage());
}
return ;
/// ^^^ What is this?
I'm not sure why your method returns a String. There's no reason for it
to do so. Is this in a servlet? If it is, then you are going to run in
to trouble with the request and response objects being members of
the class. Two simultaneous requests will completely break your application.
You can simplify the code somewhat, as well as reducing the amount of
memory required to operate by eliminating your use of a
ByteArrayOutputStream. The only downside is that your servlet will not
be returning a Content-Length with the response (which isn't that big of
a deal).

Re: How can I refresh tomcat in the java code?
Chris
Very nicely put. The only thing that I'm not clear on is your comment
about sending the data as a String. The OP is trying to return a pdf
file, which is a byte stream. I'd worry about trying to wrap that in a
String because of encoding issues.
You make a good point about two simultaneous requests breaking the app.
The other issue is of course that Jasper isn't necessarily that quick at
creating a report and the report generation is in line with the servlet
request and response.
A more sophisticated solution would probably follow a pattern of:
1. Respond to request.
2. Schedule a process (thread) to create report.
3. Return from the request saying something like Your report is being
prepared...
4. When the process in 2. is complete send an email saying please go to
... to pick up your report.
You can then make a design decision as to whether or not you want the
report generating process to allow multiple instances to run or not
(probably not in most cases).
Another tweak is to cache the generated reports if they are unlikely to
change frequently etc etc...
I've written systems that work this way. It may be that the OP was
trying to do something like this.

Tomcat podcast server
Hi everybody We've just put into service a set of web applications running under tomcat which works as a sophisticated podcast server. We deliver several thousand podcasts a day of about 20MB to 70MB in size. Originally when we started we used an Apache server (because it worked... just...) However it was clear to me that this was a poor solution for large volumes of traffic -- and I was right! So I have written a specialized http server which has the following features: 1. Adaptive rate-control algorithm which balances the load on a per-request basis to optimize the number of simultaneous requests to be serviced. The algorithm is 'pluggable' 2. Easy clustering of servers (no session state) to make it scalable. 3. Sophisticated logging to allow the easy generation of detailed reports on download activity. 4. JMX management. 5. A black-list scheme to mitigate badly written mulitmedia bots which can easily swamp a server. 6. A simple content management system to manage the import of media files. Although it is originally designed for use with mp3 files, it should work with any large media files or data downloads. The next stage of this project is to add a database controlled ad insertion facility which would insert sponsorship messages into the outgoing stream on a pre request basis. We are considering making this an open source project. If people think that this would be of interest to them to use, or if they might like to join the project, then please email me off-list at the following (substitutions obvious) alan A + T writingshow dot com So far I have only deployed this on Tomcat, but it is just a set of standard servlet 2.5 wars and should work on other containers. Currently it is running on a dual core opteron. Even at heavy loads the CPU utilization is low and it only needs about 100MB of heap to support 100 simultaneous connections. (which could represent 7GB of download) It is written using Spring and Hibernate (and a lot of other wonderful open source projects) Regards Alan Chaney - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So I decided on the fallback to write a simple filter to handle the authentication and redirection with Struts-based forms (simply because the rest of the site uses Struts) and handle the actual authentication (including password encryption) in a Struts Action. In order for the filter to receive the request, I had to remove some of the container-based security (the PUT and DELETE security-constraint still exists). The only other way I could think of handling the password encryption scheme was to write a custom Realm, which at the time, seemed over-the-top to me.

Re: How can I refresh tomcat in the java code?
Christopher,
You got it right. I was trying to generate the content, write it into server
disk and redirect it to the user.
Everyone recomended me to generate it and send it as a response.
If that's the only option, I can accept that. If there's a way to refresh
the content under tomcat server folder, it would be better.
The problem with the recomended option is: It doesn't send the content to be
downloaded.
The system.out was just a test to see if the file was generated correctly.
It seems to be, since it prints tons of unknown chars. ^^
What this code I sent previously tries to do is:
1) Generate the pdf report (working fine)
2) Create a ByteArrayOutputStream with it (working fine)
3) Show it to be downloaded by the user (not working)
This code is located on a managed bean. The method is invoked when a
h:commandButton is pressed. That's why I return a String.
Hope you guys can help me now. Sorry for the english. I finished my course
four years ago and haven't practiced since then...

These good folks are telling you to do something differently than you
are currently doing it.
Right now you are trying to:
1. generate your content
2. write the content to a file on the disk
3. redirect the user to the newly-generated file on disk
Everyone is telling you to:
1. generate your content
2. write the content out to the ServletOutputStream directly
~ (not to System.out, nor to a FileOutputStream)
No disk file; no redirect. Each request re-generates the content and
sends it back to the client (browser) as the response to the original
request.
Let me lay it out for you. You currently have this code:
| try{
| ServletOutputStream sos = response.getOutputStream();
| pdfStream.writeTo(sos);
| System.out.println(pdsStream - +pdfStream);
| response.sendRedirect(myPDF.pdf);
| sos.flush();
| sos.close();
| pdfStream.close();
| pdfStream = null;
| }catch(IOException e){
| e.printStackTrace();
| }
| return ;
You should change it to:
try{
~ServletOutputStream sos = response.getOutputStream();
~pdfStream.writeTo(sos);
~sos.flush();
~sos.close();
~pdfStream.close();
} catch(IOException e) {
~e.printStackTrace();
~response.sendError(HttpServletResponse.INTERNAL_SERVER_ERROR,
~ e.getMessage());
}
return ;
/// ^^^ What is this?
I'm not sure why your method returns a String. There's no reason for it
to do so. Is this in a servlet? If it is, then you are going to run in
to trouble with the request and response objects being members of
the class. Two simultaneous requests will completely break your
application.
You can simplify the code somewhat, as well as reducing the amount of
memory required to operate by eliminating your use of a
ByteArrayOutputStream. The only downside is that your servlet will not
be returning a Content-Length with the response (which isn't that big of
a deal).

RE: Threads
We recently resolved a similar problem on a win32 platform which presented as a java.lang.OutOfMememoryError when attempting to create a new native thread. Native threads were being created [each with their own 1Mb stack in the non-JVM heap space] in association with Thread objects as they were being managed in the JVM. In a paradox, increasing the heap available to the JVM can actually cause a thread-greedy app to fail by limiting the memory available to native threads. It's possible to change the default native thread stack size on that platform, but we didn't go down that route. It turned out to be thread leak; unnecessary threads were being created and the GC wasn't reclaiming their space [and therefore the native thread stack space].

Re: Threads
Actually another question is what is it in your application that NEEDS 2500 threads? What does the application do? Is it 3rd party or in house? Normally the creation of a thread is considered an expensive operation and typically one tries to avoid creating new threads all over the place. Hence thread pools as used by tomcat.

We are using a start up script as follows: #!/bin/sh export CATALINA_HOME=$2 export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Home export JAVA_OPTS=-Xms1024m -Xmx1024m -XX:+MaxFDLimit -server - Djava.awt.headless=false cd $CATALINA_HOME cd bin ./startup.sh Where (and how) is the 64 bit flag set?

Re: Threads
From: Stephen Caine [mailto:[EMAIL PROTECTED] I have a process that generates hundreds of threads. Running on Mac OS X 10.5.2 Server, the thread count tops out at approximately 2500. After which, the process is terminated. The heap size is set to 1 gigabyte. My question is how to increase the capacity of the JVM to handle more threads. Is the value of 2500 an absolute limit, or can it be modified by setting the thread allocation, increasing heap size or the use of another java option? What error message are you seeing in catalina.out? You are probably running out of memory. Each thread needs a certain amount of heap and stack. You may also want to look at the limits you set in the shell Defaults from mac os x 10.5.2 $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) 6144 file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size(512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited $ smime.p7s Description: S/MIME cryptographic signature

Re: Threads
Chuck, There are some thread-specific parameters you can play with, in particular -Xss. But as others have pointed out, changing one factor moves the limits on others. Your best bet (assuming you really, really need that many threads) is to run in a 64-bit process, also as previously suggested. I posted a response and hopefully I will get some good advice. increasing the size of the heap (from 1 to 1 gigs). That's not much of an increase... True enough. I meant to say, 1 to 2 gigs (but I bet you knew that).

Typicaly around 2000 or so is the thread number limit on 32-bit process due to its virtual address space limit (1 thread may claim 1MB of virtual space for stack). Running java with -d64 will invoke 64-bit JVM on leopard, and should increase the threads limit accordingly. The actual physical heap space is different story. It needs to increase only if you app/thread really use/allocate memory. But I am wondering why Tiger server did not have the issue. AFAIK, 64-bit JVM is only available on Leopard.

How to get Tomcat to pick up Oracle database connections after database shutdown?
Hi- I'm an Oracle DBA, but since I work in a small company, I've been tasked with restarting our Tomcat servers everytime I have to shut down or restart our database. (If I shutdown the Oracle database and then don't do a Tomcat restart when the database comes back up, we get HTTP 500 errors). To me, this seems silly though- Tomcat should be able to be aware that no database connection is available, but when one *does* become available, it should just pick it up, instead of requiring a restart. Does anyone here know how to configure this? Also- FYI, we are using Hibernate. Any help would be greatly appreciated. Thanks! -Steve. You rock.

rolling the console log
Hello! We are running Tomcat 5.0 in a production environment (so upgrading isn't an option) and have encountered an issue where our console log is getting to be quite large (on the order of gigabytes). Is there any way via Tomcat configuration to set this log up to roll daily? Ideally of course we'd fix the code to not print so much, but that's not an option either.

Re: How to get Tomcat to pick up Oracle database connections after database shutdown?
I think you are correct. We manage our Oracle connections ourselves using classes12 and a ConnectionPool. I have no need to restart tomcat after an Oracle bounce. I do restart my Tomcats much more often than Oracle - every day. It has been almost a year since we restarted Oracle. It could be that Hibernate is your issue. I know that Tomcat can manage connections perhaps there is something in that configuration that will help. Good luck.

Ideally, it would be. But, I neglected to mention we're running on Windows Server. That's the other reason I am looking for a configuration option. Thanks!

How can applications be isolated in Tomcat?
Hi, I'm currently putting together a solution for an off-the-shelf document management application that requires Tomcat to run a form design component. I'd like to have a single Tomcat server supporting the production and five non-production environments but isolate these instances. I’m hoping this will give some isolation so non-prod doesn’t take prod off-line but that I can also test new versions of the form design component in non-prod before rolling it into prod. It appears this could be done through virtual hosting and appbase settings but this is way beyond my knowledge and I’m just architecting the solution. I know we'll have to get a Tomcat expert in at some point in the future but just wondered if I'm going down the right or wrong road here. Any help or advice would be greatly appreciated and apologies if I got all of the terminology wrong. Regards, Pablo No virus found in this outgoing message. Checked by AVG.
