Re: How to specify windows user in runtime in tomcat?
You can try with jcifs (http://jcifs.samba.org/). It should allow you to access a remote share using a different user context, though I'd reccommend using a dedicated account for this kind of job.

Re: How to specify windows user in runtime in tomcat?
Thanks for your help. I will try JCIFS. Your are correct about using a dedicated account. But on the tomcat server which I am deploying the servlet, has other servlets and It is not feasible for me to change its access rights. Once again thanks a lot. br1 wrote: > > You can try with jcifs (http://jcifs.samba.org/). > It should allow you to access a remote share using a different user > context, though I'd reccommend using a dedicated account for this kind of > job. > > Hope it helps, > b. > > > nitin403 wrote: >> >> >> >> Juha Laiho wrote: >>> >>> nitin403 wrote: I have create a servlet which needs to read a file on a share folder. When I run tomcat service as anonymous it is not able to access read this file. But when I run tomcat service as a user who as access to this file, then it runs fine. My Question is, is it possible to something similar to this in servlet code at run time for running the servlet in tomcat. >>> >>> No, you can't change Tomcat user at runtime.

Tomcat 6.0: placement JAAS config file?
Hi all, I just got my JAAS example working on Tomcat 6.0. To accomplish that I created a directory in webapps called myjaas, placed my jsp file, and jaas.config file in that directory, and placed my jar-file in myjaas\WEB-INF\lib. Next I added the placement of my jaas.config to the 'Java Options' in the tab 'Java' in the 'Apache Tomcat Properties' window, and restarted Tomcat. My question. I tried different places of the jaas.config file. One of them in the $CATALINA_HOME\conf directory (while changing the 'Apache Tomcat Properties' accordingly). But I now had the error that the LoginModule I made could not be found. I would think a jaas configuration file should belong in the conf/ directory. I could not make it happen. Is the place correct which I described in the first paragraph, or should it be placed in $CATALINA_HOME\conf? Do you have any other comments (like the wisdom of setting the location of my jaas.config in 'Apache Tomcat Properties' ) Looking forward to your comments. Abel
Tomcat does not stay on as a windows service
I am trying to get Tomcat going on a windows machine. There are running and woking installations of Java 2 Standard Edition Development Kit version 2, update 6, with JRE and Java Web Start Apache 2.0.58 Tomcat seems to install fine; I have created and checked the paths of the system variables CATALINA_HOME and JAVA_HOME for spelling errors. However, Tomcat does not stay on as a service. It starts and a second later it is off again.

Intermittent blank page after log-n
Chris, To answer your question, Chris, I do a post to j_security_check. Actually, my "login" link really just does a GET for a secured resource and Tomcat serves up a standard j_security_check form. I only post j_username and j_password, so don't expect max size to be a problem. I was not able to reproduce the problem this morning, but after pouring through the logs I found an exception that shed some light on the problem. I saw a "connection already closed" message from one of my DAOs and I found a SQLExceptions from MOD_JK. It looks like on of my DAOs left a transaction open and the login error is really just fallout from that. I have a TODO to replace my transaction logic with Spring transactions. I'll see if the problem goes away after I do that. Here is the error: ERROR | 2007-12-13 20:53:36,085 [TP-Processor11] org.apache.catalina.core.ContainerBase.[Catalina].[www.homesassn.com].[/] - Exception performing authentication java.sql.SQLException: Communications link failure during commit().

Re: Tomcat does not stay on as a windows service
I've also found the TcpDump tool available from Microsoft's website extremely helpful in looking at this stuff. I would say it should be safe to stop the instance of java.exe holding on to 8005, but you should try to be sure it's not used for anything. Various third party software companies have been known to leverage tomcat in their own products. --David Ljuba Veselinova wrote: I found info about netstat in the windows help files. I apologize for this simple question. I'm looking at the results produced by netstat and tasklist right now. It looks like java is listening to port 8005; there appear to be two instances of java.exe running and each one of them is listening to several ports. I need java to run though. Is it safe to end the instance of java.exe listening to port 8005?

Re: problem in loading class file
I mean the path to cib.expserver.plugin.basics.ExpressServer, which your
tomcat is complaining about not being able to find.
Anyway... taking a closer look at the code you posted, I think the URI
you are using won't work
file:/c:Tud/Server/program/bin should probably be more like
file:///c:/Tud/Server/program/bin.

but when i put the same code in a web service and deploy it on the Tomcat
5.5 then it gives error:
exception classNotFoundException: can not find the class
cib.expserver.plugin.basics.ExpressServer
Some one please help me out in this regard.
The code is following:
mport java.io.*;
import java.net.*;
public class WebService {
public byte[] run(byte[] inputFile) throws Exception
{
URL url = new URL("file:/c:Tud/Server/program/bin");
System.out.println("successfully created the url");
URL[] pluginURLs = new URL[1];
pluginURLs[0]=url;
URLClassLoader pluginClassLoader = new
URLClassLoader(pluginURLs);
System.out.println("The class loader has been created successfully ");
String pluginClassName =
"cib.expserver.plugin.basics.ExpressParser";
// The following line of code gives the Exception when run
// under Tomcat but runs fine in a standalone application
Class pluginClass =
pluginClassLoader.loadClass(pluginClassName);
// The following line of code is not executed under Tomcat
System.out.println("successfully loaded the class");
return inputFile;
}

Re: swith of a connector
I'm guessing you mean switch OFF. Apart from chucking the connector config from the XML, not really. One kludge: you could try and make the connector port a property, And on startup with JAVA_OPTS='-Dfoo=-1' and ignore the exception which gets thrown by tomcat. (I can't recall if tomcat aborts startup on this type of exception) -Tim Kovacs, Robert wrote: Hello All, I'm looking for a method how I can switch of a configured connector.

Re: Tomcat does not stay on as a windows service
I found info about netstat in the windows help files. I apologize for this simple question. I'm looking at the results produced by netstat and tasklist right now. It looks like java is listening to port 8005; there appear to be two instances of java.exe running and each one of them is listening to several ports. I need java to run though. Is it safe to end the instance of java.exe listening to port 8005?

Re: Tomcat does not stay on as a windows service
Apache is running but it uses port 80. As far as I can tell (via the Task manager panel) there are no other instances of tomcat running on the machine.

Re: Tomcat does not stay on as a windows service
there is another process that already uses port 8005. check whether there are other servers (apache?) or instances of tomcat running on your machine. dirk On Friday 14 December 2007 12:31, Ljuba Veselinova wrote: > I am trying to get Tomcat going on a windows machine.

Re: Tomcat and IIS losing their link
Thanks for the reply Per... Tomcat and IIS are running on the same machine, with no external load balancer or firewall between IIS and Tomcat. When the connection is lost, IIS displays either "service is unavailable" or a "503 error" message. I only have maxThreads=400, because I didn't think it would hurt anything. I was running with far fewer maxThreads and had the same problem. The machine is a quad-core CPU with 4 gigs of ram and the load is very light. I'll look into your other suggestions. Also, I noticed in my original post that the redirectPort was wrong and I fixed that :) Any other ideas out there? -Travis - Original Message - From: "Per Johnsson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, December 13, 2007 11:52 PM Subject: FW: Tomcat and IIS losing their link (Tomcat maillist bounced my mail so I send it to you directly./per) Hi!

Tomcat Process Memory Leak?
Hi All, I am looking for some help. We are running into what appears to be a memory leak situation. The Java heap usage looks fine, but the overall Tomcat process memory usage continuously goes up and up, until it reaches the Windows 2GB per process limit, at which point it crashes. Using the Windows Performance Monitor, I am tracking the "Virtual Bytes" value of the Tomcat process. Upon Tomcat startup, it is at around 1.1GB. It then increases over time, sometimes fluctuating up and down a small degree, but the general trend is always upwards. Sometimes it jumps 40MB or more at a time. Eventually it hits the 2GB limit, and then the application stops responding and we get out of memory errors: "unable to create new native thread". Sometimes this takes 20 hours, sometimes it only takes 8 hours. We are running a third-party app on Tomcat 5.0.28 with Java 1.4.2_11. The machine is running Windows Server 2003 and has 2.5GB physical memory. We have the heap size set to 928MB. We have plans to upgrade to Tomcat 5.5.16 and Java 1.5_06 (which is also supported by the application vendor), but this will take some time, since we are in a validated environment. Any ideas about what could be causing this? I realize it could be an application-related leak, but in that case wouldn't we see it running out of heap?

Re: Tomcat does not stay on as a windows service
I don't think that's the best solution. The java.exe which is bound to 8005 is probably your tomcat service started but not active. From previous emails I assume you are running under Windows. Here's a suggestion (you may have tried this) 1. Go to the windows services manager and make sure that tomcat is set to 'manual start' 2. Reboot the machine. 3. Try the netstat to see if anything is bound to 8005. If so, investigate exactly what. 4. Start tomcat either from the task bar or the services manager 5. Check the logs to see if it started OK. I'd guess that it is possible that tomcat was already running but not responding and when you attempted to start it again you were getting the 'already bound' error message.

Question about tomcat bugzilla which is resolved but not fixed.
Hi, We've come across a problem in Tomcat 5.5.17 not completely dissimilar to the following issue: http://issues.apache.org/bugzilla/show_bug.cgi?id=33374 I notice that this issue has been marked fixed, but the comments on there indicate that the bug isnt actually fixed, and that the problem remains. Indeed, looking in the source of 5.5.25 it does not seem to contain the code in the patch in this issue. Can anyone answer why not? I wonder if i should attempt to patch the current 5.5.25 and try this fix to see if it solves our problem? Any other suggestions?

But since you are experimenting with Tomcat, I'd call it a "safe" bet that it's a Tomcat instance that's already running. You could do a telnet localhost 8005 If telnet is able to connect, type SHUTDOWN an press the Enter key (by default with Windows' telnet you won't get any visual feedback of what you type). Wait a few seconds and check whether the java.exe process bound to 8005 is still running.

Have a look at the other thread running on this list the last few days
("ISAPI JK2 ran better than JK, how can that be?"). To get a slightly
better idea what's happening when, you could also introduce a load

Most likely it would help to take Java Thread Dumps and look inside the
JVM, what your request threads are doing, when IIS gets stuck.

Server-side application leaks are really hard to figure out, because they usually only happen in a high-traffic production environment and are difficult to produce on development machines. Basically, you should look at bug reports (e.g., bugzilla) for all of the 3rd party libraries that your application uses, or at least those libraries that have been added/upgraded since this problem started occuring. For each component, search for 'memory leak' and see where that gets you.

I am using Comet for by directional communication between a native java

I noticed that when sending chunks to the Tomcat server over the request
stream Tomcat does not like to receive a CRLF at the end of a chunk, it
is only accepting the CRLF at the beginning of the following chunk.
According to rfc2616 the CRLF should be at the end of each chunk:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1
For example tomcat likes this type of chunk to be sent:
CRLF chunk-size CRLF chunk-data
But it does not like this format:
chunk-size CRLF chunk-data CRLF
Tomcat basically fires a Comet Read event to the CometProcessor with the
chunk data, but afterward fires an ERROR event with subevent type
IOEXCEPTION. I have tested this with Tomcat 6.0.14 as well as the trunk
(Dec 11th, 2007).
Here is the sample code of a java client that connects to a simple
CometEcho processor:
Socket s = new Socket("localhost", 8080);
OutputStream out = s.getOutputStream();
out.write(("POST /CometEcho HTTP/1.1\r\n" +
"Host: localhost:8080\r\n" +
"Transfer-Encoding: chunked\r\n" +
"\r\n").getBytes());
out.flush();
boolean first = true;
BufferedReader reader = new BufferedReader(new
InputStreamReader(System.in));
while (s.isConnected()) {
String line = reader.readLine();
//String chunk =
(first?"":"\r\n")+Integer.toHexString(line.length())+"\r\n"+line; //
tomcat only accepts this kind of chunk
String chunk =
Integer.toHexString(line.length())+"\r\n"+line+"\r\n"; // this format
should work according to rfc2616
first = false;
out.write(chunk.getBytes());
out.flush();
}
I was wondering if someone could explain this, and if this is by design,
or if I am using Comet incorrectly.
Thank you,

Chris Pettitt wrote:
Hello,
I'm using Tomcat 6.0.14 and its CometProcessor to create a long
running connection between an HTTP client and my server. The client
posts requests to the server using chunked transfer encoding (each
chunk is a complete XML request processed by the servlet).
I'm using a servlet that is heavily derived from the
example[1] on Tomcat's website. I've found that this implementation
blocks the worker thread - which I would not expect - if the client
sends a complete chunk and then wait some time before sending the next
chunk.
I'm using the W3C specification[2] of a chunk:
chunk-size CRLF
chunk-data CRLF
Surprisingly, if I send a chunk that does not include the last CRLF,
then the CometProcessor works correctly and does not block.
My analysis of the blocking condition follows:
ChunkedInputFilter.doRead() reads everything in the chunk except the
last CRLF. It defers reading of the last CRLF until the next read()
call by setting needCRLFParse to true at line 157. Calling
ChunkedInputFilter.available() before receiving new data will
therefore return 2, because the CRLF at the end of the chunk have not
yet been read.
The implementation of
org.apache.catalina.connector.InputBuffer.available() always delegates
to coyoteRequest.getAvailable() (in my environment, state is not
BYTE_STATE or CHAR_STATE during this call).
// org.apache.catalina.connector.InputBuffer, ~ line 260
public int available() {
int available = 0;
if (state == BYTE_STATE) {
available = bb.getLength();
} else if (state == CHAR_STATE) {
available = cb.getLength();
}
if (available == 0) {
coyoteRequest.action(ActionCode.ACTION_AVAILABLE, null);
available = (coyoteRequest.getAvailable() > 0) ? 1 : 0; //
<--- delegates here
}
return available;
}
The value that is returned by coyoteRequest.getAvailable() is set by
Http11NioProcessor (see processing of ActionCode.ACTION_AVAILABLE at
line 1218) to the value returned by its inputBuffer.available(). This
method delegates to the ChunkedInputFilter, which returns 2,
indicating two available bytes (CR, LF). Ultimately the
InputBuffer.available() method above returns 1, because
coyoteRequest.getAvailable() returned a non-zero value.
Because in.available() in the attached servlet is non-zero, the
servlet calls read() again. This time the call blocks, because when it
calls read ChunkedInputFilter.doRead() finishes reading the CRLF it
has in its buffer, it calls parseChunkHeader which makes a blocking
call to readBytes().
Is this misuse of CometProcessor? Is there best practice guidance
for managing long running connections with multiple requests with
Tomcat?
Thanks,
Chris

Re: Tomcat and IIS losing their link
Travis
take a look at this excerpt from Tomcat committer Mladen Turk..
"Just like Apache Web server for Windows, Microsoft IIS maintains a separate
child process and thread pool for serving concurrent client connections. For
non server products like Windows 2000 Professional or Windows XP the number
of concurrent connections is limited to 10. This mean that you can not use
workstation products for production servers unless the 10 connections limit
will fulfil your needs. The server range of products does not impose that 10
connection limit, but just like Apache, the 2000 connections is a limit when
the thread context switching will take its share and slow down the effective
number of concurrent connections. If you need higher load you will need to
deploy additional web servers and use Windows Network Load Balancer (WNLB)
in front of Tomcat servers. "
http://people.apache.org/~mturk/docs/article/ftwai.html
this means that Windows 2000 Pro or Windows XP has an artificial limit of
10..2 solutions
another (more capable) OS
existing OS with WindowsNetworkLoadBalancer
Nota Bene:
Any diagnosis is incomplete without looking at Java Thread Dumps as Rainier
suggested earlier..

directory listings per webapp
I want to create a webapp that just lists the content of a directory - but I don't want to turn on directory listing globally. I've seen lots of people say it can be done, just do but I've yet to find a working example. Can someone tell me what I'm missing here? I have a file: tomcat/conf/Catalina/localhost/foo.xml The contents are: Now this, all by itself works for creating the webapp, and it will get a directory listing if I enable global directory listing in the web.xml file, but I don't want that. So, I created: tomcat/server/webapps/billing/WEB-INF/web.xml The contents are: http://java.sun.com/dtd/web-app_2_3.dtd";> foo org.apache.catalina.servlets.DefaultServlet debug 0 listings true 1 foo /foo/* But this doesn't work. What do I need to do to make this happen?

Re: directory listings per webapp
There is a typo in the below. This > tomcat/server/webapps/billing/WEB-INF/web.xml Should have been tomcat/server/webapps/foo/WEB-INF/web.xml So thats not the problem.

Re: Tomcat is unable to startup in Windows 2003 Server
Looks like you have an invalid / missing server.xml file.

RE: directory listings per webapp
> From: Dan Armbrust [mailto:[EMAIL PROTECTED] > Subject: Re: directory listings per webapp > I made those two changes - but I still don't get any directory listing What do you get? Did you restart Tomcat (or insure that the webapp was otherwise redeployed)? What version of Tomcat are you using? To test what's under discussion, I changed webapps/docs/WEB-INF/web.xml to include the following: docsListing org.apache.catalina.servlets.DefaultServlet debug 0 listings true 1 docsListing / References to http://localhost:8080/docs/appdev/printer/docs/ now return a directory listing, whereas before a 404 came back. > Is my path correct for the web.xml file? Probably not. You specified a docBase of /dir/foo for the foo webapp, but appear to have been editing webapps/foo/WEB-INF/web.xml, which is not where you've told Tomcat the app is deployed. It's extremely bad practice to have a directory under the appBase that's the same as one for an app with a docBase that points somewhere else. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: directory listings per webapp
I made those two changes - but I still don't get any directory listing (I can get a file if I name it specifically - so I know that that context is working) Is my path correct for the web.xml file? Or am I missing something else?

I had tried putting the web.xml file there before - but at the time, I had the incorrect in my web.xml. Thanks a lot. I'll see if I can get access to http://wiki.apache.org/tomcat/FAQ/Miscellaneous and update the answer to this question - since the current answer is pretty poor. It would be nice if someone could update http://tomcat.apache.org/tomcat-6.0-doc/default-servlet.html as well, because in general, having documentation basically say "if you don't know how to do this already, too bad" is just bad practice ;) Thanks again, Dan - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It describes exactly what must be done - it really is that simple. You created your own problem by putting in a docBase attribute telling Tomcat where the webapp was locating and then editing a web.xml for an entirely different deployment. > It would be nice if someone could update > http://tomcat.apache.org/tomcat-6.0-doc/default-servlet.html > as well, because in general, having documentation basically say "if > you don't know how to do this already, too bad" is just bad practice > ;) I think you misunderstand the meaning of "customize" and perhaps are confusing it with "configure".

Well, it does now :) Previously - it said "This is done in TOMCAT_HOME/conf/web.xml by changing the listings property for the default servlet."

Re: CATALINA_HOME
My Tomcat directory is c:\Tomcat6\apache-tomcat-6.0.14. I tried starting startup.bat but got the error: The CATALINA_HOME environment variable is not defined correctly This environment variable is needed to run this program My CATALINA_HOME environment variable is set to c:\Tomcat6\apache-tomcat-6.0.14\conf Drop the "\conf" directory as catalina home should point to the tomcat base for most deployments and not the conf folder. Also, if you are using the Windows Tomcat Monitor process, this value should be set in the Java tab where you configure things, with an entry like -Dcatalina.home=c:\Tomcat6\apache-tomcat-6.0.14 Note that I'm only running 5.5, so pardon my answer if it doesn't apply to 6.

A work-around is to set a connectionTimeout on the element similar to what is configured on the Apache side. Personally, on a system that I actually care about the maxThreads value, I prefer to set the connectionTimeout only on the Tomcat side and configure to use CPING/CPONG on the Apache side. > Can you reproduce this for one thread with a single request?
