Tomcat 5.5.20 Stops Responding

[Etienne Lacombe]

Hello,

Setup
   Linux
   Tomcat 5.5.20
   Java 1.6

I would like some help in locating the cause of a problem on a Tomcat 5.5.20
server.

The server runs fine for some days and then suddenly stops responding to
requests - the client's browser waits for a respond and times out. 

On the server, there is no CPU usage. However, when trying to access any of
the webapps, including the Manager, they all time out.

We tried connecting to the JVM using the JConsole and we don't get a response
to that either.

I went through all the log files and could not find any significant error (no
out-of-memory, etc). Only a few error in our program but nothing that would
cause the whole server to freeze up. There were a few socket connection error
but they were not near the time of the freeze per what I could see.

If anybody could help me by directing me to what else I should look for, that
would be greatly appreciated!

Any ideas?

And yet if I copy in a new war file (I'm using ant's deploy task) I
don't see any changes to my webapp. If I look at the individual server's
webapp via the manager application, I see the changes; but I don't see
any changes by looking at the virtual host address until I restart Tomcat.

Why?

Thanks in advance.

Two ideas:
(1) I am not shure if Tomcat 5.5.20 is compatible with Java 1.6.
(2) Turn on the AccessLogValve in your server.xml config file, so you can see if 
the client requests attain your Tomcat. If not I would assume this has nothing 
to do with Tomcat. So I would check the firewall.

remove the context defs from server.xml and put them in
META-INF/context.xml, which is a dir/file inside your webapp.

this method of defining contexts is not encouraged, because you have to
restart the server to reload the config, amongst other reasons.

the default web app is called ROOT.war, your other one would be
asmalljspapp.war. put both files in the appBase dir.

when it unpacks, it'll drop the contexts like so:

appBase/ROOT/META-INF/context.xml
appBase/asmalljspapp/META-INF/context.xml

i strongly recommend that you have a read of the Context config stuff in
the docs.  you'll need to set reloadable="true".

Re: HTTP/1.1 400 no host matches server name

[David Delbecq]

In your server.xml, you probably have configured a host (probably
www.server.domain) but didn't configure the host (server).
If you don't use host aliasing (that is different webapsp for different
hostname), just configure a default host.

Java 1.6

[Marco]

Hello,

 

I read in previous post today that someone wasn't sure whether Java 1.6 is
compatible with tomcat 5.5.

This is new to me. Does anyone know more about this (more specifically, what
versions of tomcat DO work with SUN jvm 1.6)?

 

 

Regards,

 

Marco.

Re: Java 1.6

[David Smith]

I think that was pure speculation.  I use JDK 1.6 w/ Tomcat 5.5 in 
production and have had no issue.

Re: DeltaManager cannot receive message through TCP channel in Tomcat cluster

[Daniel M Garland]

Christopher Schultz wrote:


Is Eclipse re-setting the serialVersionUID for each compile, or do you
have one explicitly set in your code? (Meaning, does the
serialVersionUID ever change?)


Well in Eclipse I said 'add generated ID', but this declares a final 
static long that hasn't changed because the code in the class is the 
same. This long value matches what the Tomcat log says is the 'local' 
class name...





3) I have the same code running on both the Tomcat servers.


Are you sure? Try checking md5sum or sha1sum for the classes in
question. Object serialization should not depend upon the architecture
(that's the whole point), so switching from a 32-bit machine to a 64-bit
one should not have changed anything.


Yeh the MD5Sum matches.

Any other ideas? I've got expireSessionsOnShutdown=false on my Cluster 
element, perhaps when I redeployed the code at some point some old 
session with an old ID is being preserved somehow? I'm not using any 
session persistence either.


Another strange thing is since this started happening I don't ever see 
the session count in the manager app increase above zero, even though if 
I sit in front of the webapp my session is persisted across the 
cluster... weird.


Thanks

Re: Tomcat 5.5.20 Stops Responding

[David Smith]

Regarding the ideas:

1. tomcat 5.5 and java 1.6 should be fine together.

2. If all threads are busy, the AccessLogValve may not show anything.

Something _seems_ to be causing your jdk to turn into a zombie.  Sending 
a kill signal to the tomcat process so you get a thread dump is probably 
best. Can you post the last few messages of catalina.out?

Two ideas:
(1) I am not shure if Tomcat 5.5.20 is compatible with Java 1.6.
(2) Turn on the AccessLogValve in your server.xml config file, so you 
can see if the client requests attain your Tomcat. If not I would 
assume this has nothing to do with Tomcat. So I would check the firewall.


-- Franck

I would like some help in locating the cause of a problem on a Tomcat 
5.5.20

server.

The server runs fine for some days and then suddenly stops responding to
requests - the client's browser waits for a respond and times out.
On the server, there is no CPU usage. However, when trying to access 
any of

the webapps, including the Manager, they all time out.

We tried connecting to the JVM using the JConsole and we don't get a 
response

to that either.

I went through all the log files and could not find any significant 
error (no
out-of-memory, etc). Only a few error in our program but nothing that 
would
cause the whole server to freeze up. There were a few socket 
connection error

but they were not near the time of the freeze per what I could see.

If anybody could help me by directing me to what else I should look 
for, that

would be greatly appreciated!

Which AJP connector is used in JBoss exactly ?

Normally, the two connectors in org.apache.coyote.ajp cannot be doing

Setting ClientAuth parameter to true

[Subhash.NarayananDroupathy]

Hi,

 

I am unable to set client authentication for SSL in tomcat 5.5.2. I have
generated the certificate for the client and imported the same into the
server's keystore so that the server can verify the client's
certificate. The following is the modification I make on server.xml.

 



 

once this change is done and the server is restarted, I am not able to
hit this url https://localhost:8443  .

 

At the same time, if I change the value of clientAuth back to "false" I
am able to access the url.

 

Can some pls help where I went wrong?

 

Thanks,

-Subhash-

RE: Setting ClientAuth parameter to true

I am currently doing the samething right now and am able to access porst

Hi,

 

I am unable to set client authentication for SSL in tomcat 5.5.2. I have
generated the certificate for the client and imported the same into the
server's keystore so that the server can verify the client's
certificate. The following is the modification I make on server.xml.

 



 

once this change is done and the server is restarted, I am not able to
hit this url https://localhost:8443  .

 

At the same time, if I change the value of clientAuth back to "false" I
am able to access the url.

 

Can some pls help where I went wrong?

 

Thanks,

Filter GET and POST

[Franck Borel]

Hi,

i have a problem with an application that only accept GET requests. Now, I would 
like to know, if there is any possibility to write a filter, who is able to 
change the method from POST to GET.


I see that the FORM-Authentication could speek GET after authentication with 
POST method. Is there anybody outwhere, who knows how this was done?

Completely weird. Since we're grasping at straws, are you able to
re-deploy the old Mac servers for testing purposes? I'd be interested to
see if you do a "new" deployment on them if they will act properly.

Yes, for some reason spaces in path names are frequently the cause of
lots of head-scratching. I'm not sure if it's strictly a win32 issue or
not, but a lot of win32 folks seem to have this problem.

Something you could try is explicitly setting the value of the
CATALINA_HOME environment variable, and be sure to use the
8.3-equivalent of the path for the value. For instance:

set CATALINA_HOME=C:\PROGRA~1\thirdparty\TOMCAT
%CATALINA_HOME%\bin\startup.bat

I realize you might be using Tomcat as a service, so you'll have to
figure out how to get the same effect with the service launcher thing.
Another option, of course, is to install Tomcat into a directory with no
spaces in the path.

Hope that helps,

Actually, could you post the full stack trace? It might actually be a
bug in Tomcat that treats spaces as delimiters for path elements rather
than the commas that seem to make more sense.

Re: Tomcat crash @ midnight - but why?

[Martin Cavanagh]

Hi guys, I'm still having this problem.

Its happened 3 times now.  Always at exactly midnight.  21.09, 25.09 and 
26.09.


We have VM Ware Server as the hardware - could this cause the problem?

I have a firewall on the machine with only the HTTPS port open.

In the config file there is the standard AJP port (8009) - what does 
this actually do?


Hardware : VM Ware Server

Any ideas?

The "defaultHost" attribute allows one of your  entries to respond

Migration of Tomcat 3.2 to Tomcat 6.0

[Parandhaman, Vishnu Prasad (STSD)]

Hi,
Could anyone point out if there's a practical guide / tip to migrate
from tomcat 3.2 to tomcat 6.0 ?
(had anyone done before)
Basically there are lot of changes between the 3.2 and 6.0 versions in
terms of structure and files. 

Moreover the older tomcat 3.2 was used along with apache (through
mod_jk). 

Now when we start with the new tomcat 6 as a HTTP & Web Server it throws
up a lot of exceptions.

Thanks,

What do you mean by that? Do you just want to change the return value of
HttpServletRequest.getMethod? You can certainly do that easily.

Do you want to convert POST parameters to GET parameters? That is a bit
tougher, but is possible. I'm not sure why you'd want to do this, since
servlets do not really distinguish between GET and POST parameters --
the API abstracts that complexity away from your code.

Given that the Tomcat source code is available, you could always look in
there for inspiration!

Strange. What is the uptime of your operating system? Perhaps it's being
rebooted every night?

> We have VM Ware Server as the hardware - could this cause the problem?

Probably not, but if there's some kind of warm backup going on where the
OS is suspended for the backup, you may be running into trouble. VMware
allows the OS to respond to events (such as SUSPEND and RESUME), and
it's possible that your VM is rigged to shut down some services on
SUSPEND. I doubt that very much, but it's certainly possible.

> In the config file there is the standard AJP port (8009) - what does

If you are using a web server along with Tomcat, the AJP connector
allows the two to speak to one another. If you are using Tomcat all by
itself, you can safely disable this connector.

Re: Tomcat crash @ midnight - but why?

Hi Martin,

Its happened 3 times now.  Always at exactly midnight.  21.09, 25.09 and

We have VM Ware Server as the hardware - could this cause the problem?


What kind of network connection are you using? NAT or Bridge?

I have a firewall on the machine with only the HTTPS port open.

In the config file there is the standard AJP port (8009) - what does 
this actually do?


This is a connector, that is used to connect Apache with Tomcat. Are you using 
Apache with Tomcat? If yes look at the log file of your mod_jk 
(C:\apache2\logs\mod_jk.log).

I don't think anyone has ever made that jump before, so I don't think
there is such a guide out there. We'd appreciate any notes you take
during your upgrade, though!

Yes. Although the servlet API is mostly (if not entirely) backward
compatible, your configuration will have to change dramatically.

mod_jk can still be used today. You may decide that you do not need it,
as Tomcat's ability to serve static content has improved quite a bit in
the, uh, 4 versions you're skipping.

The first thing you have to do is throw out any server.xml files you may
have lying around from your old install. I tried upgrading from 4.1 to
5.5 by tweaking my old server.xml file, but it was a fool's errand. It's
much better to start with the server.xml file that is included with
Tomcat 6.0 and modify it until it meets your needs.

There is plenty of documentation on how to configure things in the new
versions on Tomcat. All of the documentation is available here:
http://tomcat.apache.org/tomcat-6.0-doc/index.html

The most useful things to read are probably going to be:

* Realms and AAA
* JDBC DataSources
* Connectors (if you choose to continue to use mod_jk)

That's about it. If you understood your 3.2 configuration, you should be
able to understand everything else just by reading the comments in the
server.xml file itself (there are LOTS of comments).

Hope that helps,

Re: Tomcat crash @ midnight - but why?

Check Windows Scheduled Tasks, to see what runs around that time. Could 
be a resource issue. A background task or even a load spike
from a search bot. How much memory is allocated to the VMWare instance? 
Also did you check the Tomcat logs?

Hi everyone.

Yesterday I started a 2nd Apache Server for my program.  It was
installed several months ago.  Version 5.5.0.23.

The server is running on Windows 2003 Server with Java JRE 1.5.0_11

It worked fine with my program for several hours.  Then exactly at
midnight it crashed.

Re: Filter GET and POST

[Franck Borel]

Hi Christopher,

thank you very much for your answer.


i have a problem with an application that only accept GET requests. Now,
I would like to know, if there is any possibility to write a filter, who
is able to change the method from POST to GET.


What do you mean by that? Do you just want to change the return value of
HttpServletRequest.getMethod? You can certainly do that easily.

No.

Do you want to convert POST parameters to GET parameters? That is a bit
tougher, but is possible. 
Yes, I think this is the only possibility. I found no example how this could be 
done. Any idea?



I'm not sure why you'd want to do this, since
servlets do not really distinguish between GET and POST parameters --
the API abstracts that complexity away from your code.


If I change the request from POST to GET the Servlet works. I have no
possibility to change the Servlet behind.



I see that the FORM-Authentication could speek GET after authentication
with POST method. Is there anybody outwhere, who knows how this was done?

Given that the Tomcat source code is available, you could always look in
there for inspiration!


Thanks!

Certificates, CLIENT-CERT Authentication and Authorization

[Edwin K. Brown]

I’m doing this to provide an _outline_ of what is needed to be done to get 
CLIENT-CERT authentication and authorization working in Tomcat 6. This is high 
level because each implementation will have to be done to suit your own needs.

 

This first part deals with the JAAS related code that you have to create:

 

*   The Tomcat documentation states that the 
org.apache.catalina.realm.JAASRealm has to be used to get this working. 
Actually, the JAASRealm should be extended or you create a class that extends 
org.apache.catalina.realm.RealmBase. For purposes of this post, lets call this 
class CertJASSRealm.
*   In CertJASSRealm, the authenticate(X509Certificate certs[]) method 
needs to be over-ridden/implemented to perform the certificate validation.
*   In CertJASSRealm, the getPrincipal(String username) and 
getPrincipal(String username, String subject) methods needs to be 
over-ridden/implemented to create the principal.
*   The Tomcat documentation states that it is best to implement your own 
Role and User class, and that is definitively the case!
*   Create a class to handle the role. 
*   Create a class to handle the user. This seems to be one of the keys to 
getting this right. Let’s call this class CertJASSUser. The getRoles() method 
needs to be implemented to retrieve the roles associated with this user. In the 
“demo” that I did, I had this return a set array of roles. I imagine in “the 
real world,” this would go to some external source like LDAP, a database, or a 
file, to retrieve roles, if any, for the user.
*   In CertJAASUser, implement hasRole(String role) that determines if the 
user has the role name passed in.
*   Implement a LoginModule class and a CallbackHandler class to the JAAS 
specification to suit your needs. 
*   Let’s call the CallbackHandler class CertCallbackHandler. I created a 
method that sets the certificates, public void setCerts(X509Certificate[] 
certs), for use later on during the login() process.
*   Let’s call the LoginModule implementation CertLoginModule. The 
initialize(Subject, CallbackHandler, Map, Map)  method should do any 
initialization needed. The login() method should do the “login” using the 
certificates from the CertCallbackHandler object.
*   Make sure you create the JAAS configuration file. The name of the 
module in this example is CertJaas.

 

This second part deals with SSL authentication. This has to make it possible to 
get the authentication with certificates:

*   Create a class that extends 
org.apache.catalina.authenticator.AuthenticatorBase. Let’s call this class 
CertSSLAuthenticator
*   Implement authenticate(Request request, Response response, LoginConfig 
config). The TOMCAT class SSLAuthenticator is a good class to use as a model 
for what to do for the authentication process. I think CRL lookup or OCSP could 
be used in this method.

 

 

This third part deals with what you have to do to get TOMCAT to recognize that 
you have JAASRelam code that you want to be used instead of what TOMCAT 
provides. Please note that JAASRealm is the ONLY JAAS implementation that 
TOMCAT will recognize “out of the box” without make the following changes. 
Believe me, if you don’t do the following, you will NOT get it working 
properly. You will have to extract, modify, and replace some files in 
catalina.jar.

*   Make a copy of catalina.jar.
*   Extract org/apache/catalina/authenticator/mbeans-descriptors.xml
*   Copy the mbean tag with attribute name “SSLAuthenticator”.
*   Change the name attribute to the name of the file you created to do the 
SSL authentication in the second part. In this case, the name would be 
CertSSLAuthenticator.
*   Modify the type attribute to the full class name of the SSL 
authenticator class.
*   Save the file and replace it in the catalina jar.
*   Extract org/apache/catalina/startup/Authenticators.properties
*   There is an entry for CLIENT-CERT: 
CLIENT-CERT=org.apache.catalina.authenticator.SSLAuthenticator. Change the 
class name to the class of the SSL authenticator class created. In this case, 
CertSSLAuthenticator.
*   Save the file and replace it in catalina.jar

 

The above was done because by default, TOMCAT uses it’s own files and no matter 
how you override things, your own code doesn’t get called.

 

 

The fourth part deals with the server.xml configuration.

*   The for the realm, an example would be as follows:



 

 

That is an outline of what I did to get it working. I’m sending this so that 
Google will find it and give it as a _possible_ way of getting it done. It 
appears to me that the TOMCAT team could make this a lot easier to do.

I'm not overly familiar with VMWare, but is that the memory assigned to
the OS instance?  Have you configured your JVM with custom memory
parameters?

clustering

[John Coleman]

Hi,

 

We have a thin web application that basically just manages the front end
for a remote business layer that handles the heavy session state stuff
and persistence. Basically the webapp emits and receives data as XML and
after some processing makes it available to the clients.

 

We want to cluster Tomcat in order to support more users, but I expect
each Tomcat instance will be able to manage 500+ sessions, whereas each
of our web applications can only have 250 sessions with the remote
business layer.

 

Is there a way for a single Tomcat instance to run 2 copies of the
application, each one pointing to its own instance of the business
layer? It seems silly to run 2 Tomcats, one for each application
instance, as I suspect that will waste memory and processor. I expect I
will just have to deploy the application twice to 2 different contexts,
but how is that dealt with when configuring load balancing and
clustering, or can I just use different port numbers?

 

Also, can I set a limit of 250 sessions in tomcat for a given
application so we don't blow out on the remote system?

 

John

Re: Virtual Host and dynamic webapp reloading

[Daniel M Garland]

I've gotta say I've had a miserable time with this one. I've tried 
nearly permutation of configurations in the Tomcat documentation and 
nothing seems to work; either I get the default host or a white blank 
screen.


What I need is for www.mydomain.com to host mywebapp on the default path 
and anotherapp on path /anotherapp


If I have this setup in server.xml, everything works:

...

  
  
...

However, to get the dynamic webapp reloading I've been recommended to 
move my  elements out of server.xml. As I am running muliple 
virtual hosts I understand that I cannot use conf/context.xml because 
this applies to all hosts.

So I have tried each of the following, without success:
- creating a conf/Catalina/mydomain.com/mywebapp.xml
- creating a conf/Catalina/mydomain.com/ROOT.xml
- creating a conf/Catalina/mydomain.com/context.xml
- creating a conf/Catalina/mydomain.com/context.xml.default
- creating a META-INF/context.xml in the web app (although I'd prefer to 
sort this out within Tomcat anyway)


I've also tried several variations on the docBase: ".", "mywebapp", the 
absolute path, the absolute path to the .war file...


I mean, why wouldn't this work?
in conf/server.xml:

in conf/Catalina/mydomain.com/mywebapp.xml:


Any ideas on how I can achieve the equivalent of my working server.xml 
with nested Contexts in some other file?

Regards
Dan Garland

Daniel M Garland wrote:

remove the context defs from server.xml and put them in
META-INF/context.xml, which is a dir/file inside your webapp.

this method of defining contexts is not encouraged, because you have to
restart the server to reload the config, amongst other reasons.

the default web app is called ROOT.war, your other one would be
asmalljspapp.war. put both files in the appBase dir.

when it unpacks, it'll drop the contexts like so:

appBase/ROOT/META-INF/context.xml
appBase/asmalljspapp/META-INF/context.xml

i strongly recommend that you have a read of the Context config stuff in
the docs.  you'll need to set reloadable="true".

No its definitely not being restarted automatically.  I've had the same

Probably not, but if there's some kind of warm backup going on where the
OS is suspended for the backup, you may be running into trouble. VMware
allows the OS to respond to events (such as SUSPEND and RESUME), and
it's possible that your VM is rigged to shut down some services on
SUSPEND. I doubt that very much, but it's certainly possible.
  

I don't have direct access to the VM, but I'll have this checked into.
  

In the config file there is the standard AJP port (8009) - what does
this actually do?



If you are using a web server along with Tomcat, the AJP connector
allows the two to speak to one another. If you are using Tomcat all by
itself, you can safely disable this connector.
  

Ok - I'll disable this.  There is no other Web Server involved

This is a connector, that is used to connect Apache with Tomcat. Are 
you using Apache with Tomcat? If yes look at the log file of your 
mod_jk (C:\apache2\logs\mod_jk.log).

Then the AJP port is harmless, Its a tomcat server which is working alone.

When you say "does not work", what do you mean? What happens when you
use POST?

It would be (somewhat) trivial to accept a POST request on one URL and
then forward (or redirect, I suppose) to another URL with the POST
parameters converted into GET parameters. It's up to you to find out if
a filter can do this properly, or even if that's what you want to do.

Hmm maybe this little bit of extra info helps



Not really, but answering Pid's question below might, as would following
David's suggestions. 
 
  
There is no \bin\shutdown.bat file - so this isn't being directly 
triggered.  There could of course be something triggering this in a 
different way, but not via this batch file.

656MB RAM



That's an awfully small amount of memory for a modern system, but is
probably not pertinent.
  
I know - it is very little.  That said I've got Tomcat Servers running 
on machine's with much less, without having any problems.
  
In the config file there is the standard AJP port (8009) - what does 
this actually do?



It allows connection between Tomcat and some front end such as Apache
httpd or IIS.
  
Cool to know - but not the problem then.  I can shutdown the AJP 
connector then...

Thats how much RAM the Virtual Machine has.  I'm not sure what the 
actual host machine has, but I'm assuming at least 1024 MB.  I believe 
this virtual machine is the only one on the Server.

Re: Tomcat crash @ midnight - but why?

[Martin Cavanagh]

Thanks Gabe.

I've checked the Windows Scheduled Tasks - unfortunately they are empty.

The VMWare instance has 656MB RAm.

Tomcat logs are quite boring - they only indicate that the Tomcat is 
being shutdown


The catalina logs show

All other logs I posted 5 days ago and I don't want to repost.

Thanks for everyones help

That docBase="." is going to give you nothing but trouble. Why can't you
just do this:

1. Start with a clean install of Tomcat.
2. Modify CATALINA_HOME/conf/server.xml to include your clustering
   configuration.
3. Drop ROOT.war into CATALINA_HOME/webapps
4. Drop anotherapp.was into CATALINA_HOME/webapps
5. Start up Tomcat

This should work. You don't need any crazy configuration. Your 
configuration should be in META-INF/context.xml in each of your WAR files.

Tell me more about your virtual host configuration. Do you actually need
Tomcat to understand your virtual hosts? Or, is it sufficient to have
all applications available to all host names?

Re: Tomcat crash @ midnight - but why?

[Martin Cavanagh]

the JVM is using the default parameters.  I installed JRE 1.5.0_11 (which was 
upto date at the time...)

Should I be using custom parameters?

VMWare means the the host machine, doesn't know that there is no "real" 
hardware beneath it

Martin

I'm not overly familiar with VMWare, but is that the memory assigned to
the OS instance?  Have you configured your JVM with custom memory
parameters?

How about this:

1. Check user id against requested path.
 a. Return FORBIDDEN for unauthorized access
 b. Open file and serve bytes to authorized users
2. Configure this servlet to serve all URLs like /content/*
   or something like that, instead of allowing Tomcat
   to serve content from the /content directory.

What do you mean? You want people to be able to get directory listings

Re: Virtual Host and dynamic webapp reloading

[Daniel M Garland]

Hi Chris,

I have three virtual hosts that I want to have hosting a webapp on the 
default path. Each host has a few aliases for subdomains etc. So I don't 
really want to have ROOT.war in CATALINA_HOME/webapps, partly because I 
want to keep the manager app and partly because I would have a ROOT.war 
files for each host, so I think you're saying


CATALINA_HOME/webapps
 /myapp1/ROOT
 /myapp2/ROOT
 /myapp3/ROOT

So I would've thought that I'd have the appBase of each host be 
myappX/ROOT, but what would the corresponding context.xml be? Does it 
actually work holding this file in /conf, I'm not sure about having this 
in the webapp, is it standard to have a META-INF/context.xml or is that 
a Tomcat thing?


Thanks for all the input so far folks

This should work. You don't need any crazy configuration. Your

Tell me more about your virtual host configuration. Do you actually need
Tomcat to understand your virtual hosts? Or, is it sufficient to have

Yes, as I said before...

1. Remove the context definitions from the server.xml.
2. You must not define multiple Contexts in conf/context.xml.
3. Do not define conf/Catalina/mydomain.com/.xml.
4. Do not use the path or docBase outside of server.xml.
5. Start with a fresh configuration, to ensure you aren't mixing configs
in your rush to solve the problem.
6. Include a META-INF/context.xml with your context config in the WAR.
Check that it's there by unzipping a copy of the WAR.
7. Don't forget to include the reloadable="true" settings in the context.
8. Just install the ROOT war, then configure the remaining app(s). One
thing at a time.  Tomcat will auto-deploy and copy the configs into
conf/Catalina/host/




Place the default app like so:

your/apps/ROOT.war


If this doesn't deploy/start up, check your log files and look for
errors in catalina.out and any app-local logs.

Post the file system layout after deployment, the actual context you
deployed in the war, and your current server.xml.

Re: Security restrictions for Tomcat

[alla winter]

Thanks for the quick response.
So, I want to make sure that understand it right : you are proposing that
the servlet should  display the file, instead of allowing Tomcat to invoke
Microsoft Word to disply the file content. The only issue with that is that
the file is created in the RTF format and it has control characters that
governs the formatting.

The second question was about how to set up TOMCAT not to allow the
directory listing

thanks for your help

Oh yeah, forgot about that one. Filip, Remy et al have a funny sense of
humour - they're always building crazy easter eggs into Tomcat.

No, Martin, there's no secret scheduled shutdown setting.

I've asked about the logs before, but I'll ask again...
What's in the logs immediately before the shutdown?

You'll need to look in catalina.out, any app logs and the access log for
the app.


If you're using the default JVM settings, there's a chance that you
might not be running on the server JVM, so your app may have a limited
amount of memory at it's disposal (32Mb if memory serves).  If it's
hanging for some reason (e.g. an app internal job at midnight?) would
VMWare shut it down as a bad/dead process?

Evidence of this might be found in the logs, by unexpected gaps in
access log traffic, error messages in catalina.out etc.


You could also configure jvm gc logging, (google for this), which may
tell you something.

You can deploy the manager app even when there is a ROOT application
deployed.

Well, I didn't say that, but if I had said something like that, I would
have suggested:

CATALINA_HOME/webapps (contains nothing)

VIRTUAL_HOME/www.domain1.com[/webapps]
ROOT
myapp1
myapp2
...

VIRTUAL_HOME/www.domain2.com[/webapps]
ROOT
myapp1
myapp2
...

You will need separate  elements in your server.xml file. The
"appBase" for each of these should be VIRTUAL_HOST/www.[whatever].com,
or whatever you choose to be your directory layout.

If you are deploying all the same applications on all virtual hosts,
then you can ignore the whole virtual host concept and just use a
default host to serve everything regardless of the hostname.

> So I would've thought that I'd have the appBase of each host be 
> myappX/ROOT

No, no no. The "appBase" tells Tomcat where to look for deployable
applications, not the directory where /index.html should be found. This
is NOT the same thing as DocumentRoot in Apache httpd. Shave off the
ROOT and you've got yourself a decent configuration. If there is a
directory called ROOT (or a WAR file called ROOT.war) in the appBase
directory, /that/ application will be used as the one that is deployed
with no context path (i.e on / instead of /myapp).

> but what would the corresponding context.xml be?

The context.xml file should not contain any path information whatsoever.
All you need is JNDI resources, realm configuration and stuff like that.
This is a perfectly good context.xml file:



You don't need anything else unless your application needs special
configuration. If you don't have anything in your context.xml file, you
can even leave it out, since Tomcat will give you the default deployment
configuration (which is an empty config).

This is a Tomcat thing only.

I've not benchmarked it, but our annual traffic high point passed (with
a traffic increase) and without the normal tuning and tweaking this
time.  So I'd have to say anedoctally - yes.

I'm not sure if compiling Tomcat under 1.6 would produce even better
performance - I don't know enough about byte code to comment on that,
but some of the more enlightened listers may do.

I think you are misunderstanding what is really going on at a
fundamental level. Tomcat will never invoke Microsoft Word for any
reason, unless you have something truly crazy going on in the background.

What I'm suggesting is that you write your own code to serve the
contents of a static file. It's pretty simple: open the file, write the
appropriate HTTP headers, copy the bytes to the servlet output stream,
close all streams, and you are done.

> The only issue with that is that

This is irrelevant. It doesn't matter if you are serving a text file or
a PDF, you are just serving bytes to the web browser.

Actually, I think you have to specifically enable directory listings. If
you haven't enabled them, then you shouldn't be getting any. Are you
able to get a directory listing?

I don't think so.  Lack of RAM might cause performance problems due to
excessive paging, but it's not going to cause a shutdown.  If there were
JVM heap issues, there would be OOME exceptions logged, and Tomcat would
not be going through a normal shutdown.

That just means you installed from the .exe rather than the .zip
distribution.  Something could still be running around terminating the
Tomcat service at midnight.  Take a look at the properties for the
Apache Tomcat service in the Windows Control Panel -> Admin Tools ->
Services, and see if it has any dependencies or other unusual
characteristics set.

[Alexey Solofnenko]

InstallShield now has auto update feature too. Plus there is auto update 
in antiviruses, Google Pack, other products. Also disk defragmenters may 
want to reboot the machine to defragment system files. Sometimes they 
log messages in EventLog.

Keep the ideas coming guys!

just to to check - there is no hidden setting in Tomcat which says - 
shut me down at midnight sometimes for an inexplainable reason?

Hi guys, I'm still having this problem.

Its happened 3 times now.  Always at exactly midnight.  21.09, 25.09 
and 26.09.


We have VM Ware Server as the hardware - could this cause the problem?

I have a firewall on the machine with only the HTTPS port open.

In the config file there is the standard AJP port (8009) - what does 
this actually do?


Hardware : VM Ware Server
OS: Win 2003
Tomcat Version: 5.5.23

Any ideas?

Thanks

Hi everyone.

Yesterday I started a 2nd Apache Server for my program.  It was
installed several months ago.  Version 5.5.0.23.

The server is running on Windows 2003 Server with Java JRE 
1.5.0_11


It worked fine with my program for several hours.  Then 
exactly at

midnight it crashed.

Dienst "Apache Tomcat" wurde unerwartet beendet. Dies ist 
bereits 1

Mal passiert. - Which translates to,
Service "Apache Tomcat" stopped unexpectedly.  This has 
happened once

already.

The catalina logs show

Which unfortunately isn't really particularly useful.  I can't 
see any
other logs regarding this.  How do I find out why my Tomcat 
crashed?


Thanks

Thanks Pid - some good tips

Oh yeah, forgot about that one. Filip, Remy et al have a funny sense of
humour - they're always building crazy easter eggs into Tomcat.

No, Martin, there's no secret scheduled shutdown setting.
  

phew :)

I've asked about the logs before, but I'll ask again...
What's in the logs immediately before the shutdown?
  
Like I said nothing - I posted them once before - but here they come 
again.  This time I'm even including the Std-Out, which is just junk 
from my program..although now I see something that could either be 
the problem - or a symptom of the problem.


Each time when Tomcat has crashed, it has been at midnight.  At exactly 
midnight my program changes log directorys - from 20-09-2007 to 
21-09-2007.  This is a TimerTask.  A thread which runs at exactly 
midnightat each of these crashes it has reported "Can't create 
directory '\.cs-aterm\logs\SYSTEM\2007-09-25'".  I can't help wondering 
if that might somehow be related.  However if that happens, it should 
result in no logs being produced, not in Tomcat crashing.


I've also been using this logging technique for years (inherited from 
the previous programmer).  It always worked fine - on many servers.

You'll need to look in catalina.out, any app logs and the access log for
the app.


If you're using the default JVM settings, there's a chance that you
might not be running on the server JVM, so your app may have a limited
amount of memory at it's disposal (32Mb if memory serves).  If it's
hanging for some reason (e.g. an app internal job at midnight?) would
VMWare shut it down as a bad/dead process?
  

Hmmm - how houw I change the JVM into a Server JVM?

Evidence of this might be found in the logs, by unexpected gaps in
access log traffic, error messages in catalina.out etc.


You could also configure jvm gc logging, (google for this), which may
tell you something.
  

That sounds like this is worth looking into

no i don't think so - (but how do I control that - It would be cool to 
use that).  Its pretty much a standard Tomcat installation - with HTTPS 
turned on and HTTP turned off.


My standard tomcat logs only change their  filenames, when i restart tomcat.

Server vs client JVM is likely to be totally irrelevant, but in any
event, run the tomcat6w.exe program, go to the Java tab, and see what is
set for Java Virtual Machine.  If the "Use default" check box is set,
clear it, and enter the location of the server jvm.dll file (e.g.,
C:\jdk1.6.0\jre\bin\server\jvm.dll).  You'll have to change the location
to match your JVM installation, of course.

There is no \bin\shutdown.bat file - so this isn't being directly 
triggered.



That just means you installed from the .exe rather than the .zip

There don't seem to be.

The Server is started with \Tomcat\bin\tomcat5.exe //RS//Tomcat5 - is 
that normal?


A temp solution appeared there - it is possible to tell windows what to 
do if a service stops - i could tell it to automatically restart - which 
would be a solution - not the best but i saves me having to monitor it 
at midnight

Tomcat is running a Windows service, so command line options cannot be
used.

SESSIONS.ser (Too many open files)

[Ranjan Kumar Baisak]

Hi Experts,
   I am facing a strange problem in my tomcat application. 
Suddenly it generates following Exceptions


java.io.FileNotFoundException: 
/server/http/site/music.yamaha.com/site/work/SESSIONS.ser (Too many open 
files)

  at java.io.FileOutputStream.open(Native Method)
  ..


And some other application FNF

java.io.FileNotFoundException: 
/server/http/site/ssd.com/site/dist/tilesCopy/en_US/siteTree.xml (Too 
many open files)

  at java.io.FileInputStream.open(Native Method)
...
...

What might be the possible causes that generates such exception?
Some people suggested me to check whether application is running on 
development mode, and if yes then change it to deployment mode i.e.


   configuration
  deployment
  


I am not using any  in my web.xml.
I would appreciate your thoughtful suggestion.

regards,
Ranjan

Are you simply running out of disk space, or file handles, or some
other OS resource?

Re: SESSIONS.ser (Too many open files)

[David Smith]

I would think this would be the root issue: "Too many open files"

What OS are you running.  Some limit the number of open file handles.  
Also might want to check to be sure you are closing files when finished 
with them in your webapp.

Is this the case for all 3 shutdown instances?

If so, I'd suggest that understanding why that is happening will lead
you to the cause of the shutdown...

You're not really logging much from your app it would appear - is there
any way to increase the logging level, or haven't you got much in the
way of logging in the code?

Re: HTTP/1.1 400 no host matches server name

[David Delbecq]

Are you behind an apache server, using mod_jk? Or is tomcat accessed 
directly. As omeone suggested, check you have a valid default host in 
tomcat. If you are behind an apache web server, you might to check it's 
not the apache server that answer with HTTP400 (tomcat error pages 
always include tomcat reference and are white and blue by default). You 
could also add aliases to your localhost  to match "myserver".

Re: Security restrictions for Tomcat

[alla winter]

I am confused now
web.xml instructs Tomcat what application needs to be called for a given
MIME type
for example:
- 
  rtf
  application/vnd.ms-word
  

 Tomcat pass the request to the  third party application based on the MIME
type, so if I show the link to the .RTF file and the user selects the link,
the Microsoft Word will display the selected file.  The same with PDF files
- the  the ADOBE reader is invoked
My undesraning is that by writing file bytes to the servlet output, I am
just creating and HTML file where the file content is a body of the HTML

But if I output the bytes of the file to the servlet output, it will look
the same way as I would open RTF file in the notepad - with all controll
characters inside.
Unless I am missing something here...


As far as directory listing - yes, I do see the directory listing for all
folders that are underneath of my application except WEB-INF and I didn't do
any special set up for that - I am using all default XMLs except the
web.xmlwhere I am defining my servlets.

I appreciate your help.

No, unless you've got some weird setup on a windows machine Tomcat is
not opening MSWord.  The mime type is sent to the browser in an http
header, and the browser decides what to open it with.

For example, if you didn't have MSWord installed, but had, say,
OpenOffice, you could find that OpenOffice opens the file.

Again no, the output is handled by the browser - if you set:

 Content-Type: text/html

the browser will do as it's told and try to process the output as an
HTML file.

Yes, the Content-Type header is the key to this.

RE: Security restrictions for Tomcat

Directory listings are disabled by default, as described in the
DefaultServlet section of the conf/web.xml file.  You have either set
the listings parameter to true, or you have overridden the
DefaultServlet with one of your own in your webapp's WEB-INF/web.xml
file, and that one is displaying the directory contents.

BASIC auth question, simple example...

[Greg Morphis]

Hi, I'm a n00b so bare with me!

I've got Tomcat 5.5 installed on my machine to the default location
c:\Tomcat5.5

I'm trying to get a simple example of BASIC auth running and I'm not
having any luck.

I created the folder
C:\Tomcat5.5\webapps\security\
In there I have
C:\Tomcat5.5\webapps\security\index.html
with just a simple "Hello World"
and
C:\Tomcat5.5\webapps\security\WEB-INF\web.xml

In the web.xml file I have

http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">

   
  
 Protected Area
 
 /security/*
  
  
 
 dau
  




  BASIC
  Example BASIC Authentication Area




  dau



and in the conf/tomcat-users.xml I added the dau role.
This is not working. When I run the page I'm taken to the Hello World
page, why am I not prompted for the password?

It has to be something simple!?

Thanks!

We dont have much file handling operations in our web applications,

What OS are you running.  Some limit the number of open file

when finished with them in your webapp.


its running on  *Red Hat *Enterprise Linux AS 4. I am at all not good

Hi Experts,

What might be the possible causes that generates such exception?
Some people suggested me to check whether application is running on 
development mode, and if yes then change it to deployment mode i.e.


   configuration
  deployment
  


I am not using any  in my web.xml.
I would appreciate your thoughtful suggestion.

regards,

To see your current settings use 'ulimit -a'. If you want to make 
permanent changes edit /etc/security/limits.conf
Everything in a system is a file, not just a single webpage, the default 
are not enough for your requirements.

Ok now I got it. default value for open files is 1024 and I think I need 
to increase open file descriptor limit.

Thanks a lot, I hope not to get this problem again.

You mapped security constraint to folder "/security/*" in your webapp. 
That means http://server/security/security/*
You probably should, considering where you index.xhtml is, map the 
security constraint to /* :)

RE: Tomcat crash @ midnight - but why?

Doesn't quite fit the symptoms.  When a webapp calls System.exit(), the
following entry does NOT appear in the logs:

Sep 26, 2007 1:23:07 PM org.apache.coyote.http11.Http11Protocol pause
INFO: Pausing Coyote HTTP/1.1 on http-8080

Whereas when the service is stopped or the shutdown string is sent to
the shutdown port, the above message does appear in the logs.  The OP
did report that the "Pausing ..." message is present.

In unix, opened pipe (stdout/stdin, etc) and network sockets are 
considered opened files btw

Tomcat 5.5.20 Stops Responding

[Etienne Lacombe]

Hello,

I would like some help in locating the cause of a problem on a Tomcat 5.5.20
server. I looked at many things but I don't know what else to look for.

Setup
   Linux
   Tomcat 5.5.20
   Java 1.6

The server runs fine for some days and then suddenly stops responding to
requests - the client's browser waits for a respond and times out.

On the server, there is no CPU usage. However, when trying to access any of
the webapps, including the Manager, they all time out.

We tried connecting to the JVM using the JConsole and we don't get a response
to that either.

I went through all the log files and could not find any significant error (no
out-of-memory, etc). Only a few error in our program but nothing that would
cause the whole server to freeze up. There were a few socket connection error
but they were not near the time of the freeze per what I could see.

If anybody could help me by directing me to what else I should look for, that
would be greatly appreciated!

Etienne
