You don't tell us which version of Tomcat you're running, so it's hard to point 
you to the correct docs for your version on the Web.  However, if memory 
serves, look at the file RUNNING.txt in your Tomcat directory.  There's a 
section in there about setting up multiple Tomcats on the same machine.

 Subject: Three tomcat instances


 I write a java web service and depending on a result i want it to call
 other web service (http://localhost:80/axis/serv.jws).
 But, i want serv.jws to be handled by three different servers
 depending
 on where i want to send it.
 How can i run three tomcats simultaneously?I read the server
 documentation,but mentions that only one server i can set
 into server.xml

 Any help appreciated.

RE: How to reference Shared Libraries with TOMCAT

 From: Sarva [mailto:malhotrasa...@yahoo.in]
 Till now I have been deploying all the JARs in WEB-INF/lib
 folder of my Web Application and run it to satisfaction.

OK.

 Now we need a mechanism by which the JARs will not be stored
 in WEB-INF/lib
 but in a centralized location for example c:/lib, and all tomcat Web
 Applications should refer to this folder for all JARs required during
 runtime.

Why?  You will make a maintenance nightmare for yourself when the version of a 
jar changes for one application, but another application still needs the old 
version.

 How can I do this.

Depends on your Tomcat version, which you didn't bother to tell us.

Hello,

You need to add those JAR files on central location add these files in Class

If you have multiple tomcats and multiple applications then you have to put
the jars on a separate location and add these in class path environment
before starting any of the tomcat, it will work for more then one tomcats
and more then one applications, thanks.

What is a typical Comet event flow, with multiple READ events?

2009-06-03 Thread Pieter Fibbe

Hi,

I have been trying to write a Comet webapp, but it's not totally clear
to me when and how CometEvents are exactly triggered. According to the
documentation a typical life cycle of a Comet request will consist in
a series of events such as: BEGIN - READ - READ - READ -
ERROR/TIMEOUT (from: http://www.mbaworld.com/docs/aio.html).

It seems that a READ event is triggered only by a POST request, but
the event flow that I am getting never triggers more that one READ
event in a row, for example: BEGIN- -READ-END, BEGIN- -READ-END,
etc. Is the way a comet application should work? So you have to
establish a new connection every time you get a response from the
server and wait for the next response, process it and start from the
beginning? My idea was having one connection and reuse that connection
for multiple requests. So on the client side there would be something
like the following code:


script
var xhr;
function init() {
xhr = new XMLHttpRequest();
});

function triggerEvent() {
xhr.open(POST, /servlets/cometservlet, true);
xhr.send(something);
}
/script
input type=button onclick=triggerEvent /


Since it is not possible to invoke xhr.send() several times without
opening the connection first (xhr.open()), a CometEvent.BEGIN is
always triggered first. So how can the BEGIN - READ - READ - READ
series (given in the documentation) be implemented?

Re: Just a few questions on my Tomcat Configuration

Sorry about that Chuck, I'm a little new to this here...

Tomcat version is 6.0.18.

My /conf directory is the standard windows installation directory structure
it contains no other sud-directories, just my config files.  If I modify the
directory and add the recomended structure, will Tomcat pick it up, or is it
different because this is the Win32 installation?

also there is a way in Tomcat to do a contextual reload of the xml files
automatically as soon as they change, but I forget how.  Any takers on this?

  I have tomcat running on a dedicated Windows server (this
  is a web server).

 Tomcat version?  Always tell us that - we're not mind readers.

  My /conf directory is not exactly the same as what it is
  calling for (Approach #2).

 What's different?  Again, we can't read your mind.  Choice of the two
 approaches is up to you; some find it easier keeping Context elements
 inside each webapp (in META-INF/context.xml), some prefer to keep them
 separate from the webapp itself by placing them in
 conf/Catalina/[host]/[appName].xml.

  Bind each virtual host to the corresponding sub-domain (not
  a clue on how to do this)

 Use the sub-domain as the name attribute on the associated Host.

Re: How Can I integrate tomcat6 cometprocessor + apache2.2 (load balancing)

I am trying to integrate tomcat6 and apache2.2 for load balancing.

I tested connecting tomcat6 and apache2.2 (not nio) and load balancing, and
it was successful..
By the way, I must use cometprocessor of tomcat6, so that I have to use nio
protocol.
When I send http request(comet timeout 10 sec), it send response
immediately..
The right action is that client receive response after 10 sec.
In this case, how can I integrate tomcat6 and apache2.2?

I saw the sentence...
IMPORTANT NOTE: Usage of these features requires using the APR or NIO HTTP
connectors. The classic java.io HTTP connector and the AJP connectors do not
support them.


please let me know the solution..

When a browser is a client, you typically don't have multiple read events.

That depends on your OS - which you haven't told us.  Tomcat should show up as 
a Java process, so if you're running a recent Java (which you also didn't tell 
us) then jps should tell you some possible process IDs.

 That depends on your OS - which you haven't told us.  Tomcat should show
 up as a Java process, so if you're running a recent Java (which you also
 didn't tell us) then jps should tell you some possible process IDs.

This is not a Solaris training list.  Since you're acting as a system 
administrator, you need to have system administrator knowledge.

Try the jps program, as already suggested.  Look at the man pages for netstat 
to see what option to use to display the pid (it's usually -o).

   How I can free the port without going to the original tomcat shutdown.

You may be able to use Sysinternals' tcpview.exe to close those
connections, but it's possible that you'll only be able to close active
connections, and that you can't unbind a bound IP port.

I don't expect this to work, but you can try it.

Why not just change the configuration and bounce Tomcat?

As Peter pointed out, doing so is a really bad idea.  The OP should continue to

Don't *EVER* set the CLASSPATH environment variable - that causes no end of

Re: sqljdbc, integrated sql server authentication and multiple webapps - only the first app can connect

2009-06-03 Thread vsoneta

Hi,

I had the same problem.

I resolved the issue by deleting sqljdbc.jar from both the apps and added
that jar in the tomcat's lib folder along with the .dll and also .dll to
your windows\system32.

Make it sure the system's Path is set to your windows\system32.

Hope so this helps

The

If you're using a native library (sqljdbc_auth.dll), you must be using a
Java wrapper that loads the library and then puts calls through to it. I
wonder if you are putting the JNI wrapper in your webapp's lib directory
and that's trying to double-initialize the DLL.

The DLL file should have come with a JAR file, too. Where do you have
that JAR file installed? If you have it once per webapp, your problem is
probably double-init. Try moving the JAR file that came with the DLL
into Tomcat's lib directory (that is, $CATALINA_BASE/lib).

What authentication mechanism are you using already? FORM? BASIC?

With BASIC or DIGEST authentication, it's easy enough to put the
credentials into the request that the remote server sends to you.

If you're using FORM authentication, it's more complicated because
Tomcat's authentication /requires/
request-challenge-credentials-repeat-request. If you use
securityfilter (http://securityfilter.sourceforge.net), you can do
drive-by logins by just calling j_security_check directly (without an
initial request).

Another option (which I prefer) is to provide a service that is oriented
toward these clients which accepts credentials in a different form.
Don't use container-managed security for this service. Instead, accept
credentials in some other way. You can accept username and password, or
you could even accept a single token which is encrypted using a
pre-shared key.

RE: Just a few questions on my Tomcat Configuration

 From: Josh Gooding [mailto:josh.good...@gmail.com]
 Subject: Re: Just a few questions on my Tomcat Configuration

 Tomcat version is 6.0.18.

Good.

 My /conf directory is the standard windows installation directory
 structure it contains no other sud-directories, just my config files.

Tomcat will create the subdirectories as needed, such as when you deploy a .war 
file that has an context.xml file in its META-INF directory.  It won't create 
them until needed.

 If I modify the directory and add the recomended structure,
 will Tomcat pick it up

Yes; it's all Java, so it doesn't care what the platform is.

 also there is a way in Tomcat to do a contextual reload of the 
 xml files automatically as soon as they change

Depends on which .xml files you're talking about.  For WEB-INF/web.xml, that's 
controlled by a WatchedResource element nested inside a Context element.  
That's enabled by default for all webapps, since it appears in the global 
conf/context.xml file.  You can add other WatchedResource elements to the 
global or individual webapp Context elements to monitor changes in other 
files, if desired.  You can also set the reloadable attribute for any Context 
to have Tomcat watch for changes to the webapp classes and jars.  Note that 
none of the monitoring mechanisms should be used in production, due to the 
overhead incurred.  Doc for Context:

 Looks like the last SecurityFilter build was released on Dec. 14,
 2004, which makes me hesitant to use it.

The servlet specification regarding authentication and authorization
hasn't changed in a long time, so newer releases haven't been warranted.

The project is definitely active, in spite of a lack of recent releases.

 I am wondering if it is possible to use JavaScript to include the
 user name and password in the HTTP header when the link is clicked.

Yuk. Relying on javascript for security is, IMO, a terrible mistake.

 Does this mean that there is no way to authenticate against Tomcat
 server unless the server initiated the request itself?

No, that means that the client must make a request for a protected
resource /before/ the client can provide credentials to the server (i.e.
no drive-by logins).

It really shouldn't interfere: it should actually have no effect at all.
startup.sh calls catalina.sh which calls setclasspath.sh and at the
beginning of that script is

# First clear out the user classpath
CLASSPATH=

Now, of course, anyone can modify these scripts and totally screw
everything up, but simply setting the CLASSPATH environment variable at

java.net.SocketException: Too many open files

2009-06-03 Thread John . C . Cartwright

Hello All,

something strange happened to our tomcat 5.5 instance running on RHEL Linux.

Suddenly we began getting the exception listed below written out to the
catalina.out log.  It was repeated approx 4 million times w/in a couple
of hours until it filled up the file system and hung tomcat.  This is a
pretty standard setup.  Requests come into apache and then a ProxyPass
forwards onto tomcat. Apache has a directive like the following for each
context:

ProxyPass /gdsg   ajp://localhost:8009/gdsg


Can someone please help to to understand what might cause such an
exception?  Is there a good way to see the files tomcat has open?  I'm
not sure that a simple lsof -u tomcat will show them all.

Thanks so much for the help!

File descriptor exhaustion - the process has run out of fds.  Any i/o could use 
a file descriptor, whether that's socket to httpd, socket to database or access 
to a file.  Naively, I'd expect lsof to show them - what makes you think it 
isn't?

If you're lucky, you merely need to find the piece of code that's leaking 
resources and fix it - which I accept isn't always the easiest of jobs.  If 
you're *un*lucky, it's load related and you've just plain run out.  I'll leave 
the UNIX specialists to suggest ways of increasing the number of fds per 
process, but there have been some recent threads on here.

But not on Windows.  The corresponding Windows script only sets CLASSPATH if 
running with a JDK and it can find tools.jar (which is odd, since Tomcat no 
longer uses javac).  Under any other conditions (such as running with a JRE), 
the CLASSPATH is left untouched.

Setting CLASSPATH globally (which a quicktime install does) can be disastrous 
for other programs, if not Tomcat; that environment variable has long outlived

[SECURITY] CVE-2009-0033 Apache Tomcat DoS when using Java AJP connector

2009-06-03 Thread Mark Thomas

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

CVE-2009-0033: Apache Tomcat denial of service vulnerability

Severity: important

Vendor:
The Apache Software Foundation

Versions Affected:
Tomcat 6.0.0 to 6.0.18
Tomcat 5.5.0 to 5.5.27
Tomcat 4.1.0 to 4.1.39

The unsupported Tomcat 3.x, 4.0.x and 5.0.x versions may be also affected.

Description:
If Tomcat receives a request with invalid headers via the Java AJP
connector, it does not return an error and instead closes the AJP
connection. In case this connector is member of a mod_jk load balancing
worker, this member will be put into an error state and will be blocked
from use for approximately one minute. Thus the behaviour can be used
for a denial of service attack using a carefully crafted request.

Mitigation:
6.0.x users should do one of the following:
 - upgrade to 6.0.20
 - apply this patch http://svn.apache.org/viewvc?rev=742915view=rev
5.5.x users should do one of the following:
 - upgrade to 5.5.28 when released
 - apply this patch http://svn.apache.org/viewvc?rev=781362view=rev
4.1.x users should do one of the following:
 - upgrade to 4.1.40 when released
 - apply this patch http://svn.apache.org/viewvc?rev=781362view=rev

supplying illegally URL encoded passwords. The attack is possible if
form based authenticiaton (j_security_check) with one of the following
authentication realms is used:
 * MemoryRealm
 * DataSourceRealm
 * JDBCRealm

Mitigation:
6.0.x users should do one of the following:
 - upgrade to 6.0.20
 - apply this patch http://svn.apache.org/viewvc?rev=747840view=rev
5.5.x users should do one of the following:
 - upgrade to 5.5.28 when released

4.1.x users should do one of the following:
 - upgrade to 4.1.40 when released
 - apply this patch http://svn.apache.org/viewvc?rev=781382view=rev

Example:
The following POST request should trigger an error (500 server error or
empty response, depending on the configuration) if the ROOT web
application is configured to use FORM authentication:

POST /j_security_check HTTP/1.1
Host: localhost

j_username=tomcatj_password=%

Re: Just a few questions on my Tomcat Configuration

Excellent.  So let me see if I have everything straight here:

I use virtual hosting to create /abcapps and /xyzapps and install the
program in each directory.  In the Host section, bind the sub-domain to
them and then I should be able to login per subdomain and have everything
completely seperate (since I have files being uploaded to the server).  It's
all housed in the Server.xml file right?

One more quick note, is there a way that I can break out certain sections of
the server.xml file into a seperate .properties file?  I have some of the
properties broken out of the web.xml, but can I do the same thing in the
server.xml file since it is a core file that tomcat relies on for it's
configuration?

Thanks again!

ask our customer to distribute it to its users and have them install
certificates in their browsers.

Is there a reason why not many people recommended CLIENT-CERT authentication
on this thread?

Thanks

  Alec, so basically members of your client company should be able to have
  direct access to a servlet that is otherwise restricted to a handful of
  users who must authenicate themselves with a username/password login,
  right?
 
 
  Yes, this is exactly what we need.
 

 Awhile back, I had a request to do something similar.  However, in this
 case
 the (then) client was providing a portal that their users logged onto, and
 proxied to our app.  What we did is to clone the webapp and make the clone
 authenticate with CLIENT-CERT.  The client portal would then proxy to the
 clone and provide the same certificate for all users that it had
 authenticated (which Tomcat then accepted).  In this case, even if a
 blackhat could find the URL for the clone, she still couldn't get in.

 
 
  One solution to this situation would be to create a simple servlet that
  sniffs incoming request IPs, if they match the range/set of IPs of your
  client, then you bypass the authenication mechanism of your existing
  servlet
  and give them a full view of whatever goodies your servlet has.  If
  incoming
  requests don't match the IPs then bounce them off somewhere.
 
  However this approach is not a complete solution, a very interested
 party
  could observe your system and deduce that it was based upon privileged
  IPs
  and then spoof them.   It all depends upon how important this servlet is
  you
  and your organization.  If it is absolutely mission critical, then
 you'll
  want to use SSL and require logins.
 
 
  The servlet is not mission critical and provides only read-only access. I
  like this idea, but as Hassaan pointed out it does not allow our customer
  users to access this page if they are outside of the VPN.

   I may not be explaining it clearly.
  
   We have one corporate customer who is putting a link to our servlet on

  need
   custom authentication. We can also tell the customer to put whatever
 we
   need
   in the link, such as HTTP headers.
  
   Does this give you enough information to propose a solution?

If you have a customer who would like to put a link on a web page

IIS Connector Redirect to Localhost?

2009-06-03 Thread Patrick Markiewicz

Hi,

I configured the isapi_redirect file for tomcat using the
instructions I found online.  The only twist I added, was instead of
defining the ISAPI filter for the entire website, I used a wildcard map
and instructed IIS 6.0 to use isapi_redirect.dll as the high priority
wildcard map for an empty directory called C:\myapp.  In my worker map,
I defined /myapp to go to the ajp13 connector.

If I visit the page in plain http, it seems to work fine all
the time.  I.e. http://www.example.com/myapp brings up the page. When I
visit the page in https, ajp13 tries to redirect the client to
localhost:8009 (which of course is not valid).  But when I reload the
page, it goes to the https://www.example.com/myapp.  How can I avoid the
redirect to localhost?  I suspect I just need to put www.example.com
http://www.example.com/  somewhere in server.xml, but there were 3
places with localhost specified, and I wasn't sure which one I should
replace.

 

Thanks.

 

Patrick

3 possiblities
1)misconfig with AJP connector

2)so you're running out of heap 
tweaking JAVA_OPT minheap and maxheap parameters would help
a 2004 post http://forums.sun.com/thread.jspa?messageID=10055131 says it best

The default stack size is 256K on UNIX and on 32-bit Windows operating systems. 
To set Stack
size

java -XX:NewSize=128m -XX:MaxNewSize=128m -XX:SurvivorRatio=8  -Xms512m -Xmx512m

1. Setting the New generation heap size
 -XX:NewSize
 Use
this option to set the New generation Java heap size. Set this value to
a multiple of 1024 that is greater than 1MB. As a general rule, set
-XX:NewSize to be one-fourth the size of the maximum heap size.
Increase the value of this option for larger numbers of short-lived
objects.(problem is you would have to know which objects are short-lived)

Be sure to increase the New generation as you increase the number of
processors. Memory allocation can be parallel, but garbage collection
is not parallel.

2. Setting the maximum New generation heap size
 -XX:MaxNewSize
Use this option to set the maximum New generation Java heap size. Set
this value to a multiple of 1024 that is greater than 1MB.
(this is the ceiling for New Generation heap)

3. Setting New heap size ratios
 -XX:SurvivorRatio
 The New generation area is divided into three sub-areas: Eden, and two 
survivor spaces that
are equal in size. 

Use the -XX:SurvivorRatio=X option to configure the ratio of the
Eden/survivor space size. Try setting this value to 8, and then monitor
your garbage collection.

4. Setting minimum heap size
 -Xms
Use this option to set the minimum size of the memory allocation pool.
Set this value to a multiple of 1024 that is greater than 1MB. As a
general rule, set minimum heap size (-Xms) equal to the maximum heap
size (-Xmx) to minimize garbage collections. 

5. Setting maximum heap size
 -Xmx
 Use this option to set the maximum Java heap size. Set this value to a 
multiple of 1024 that
is greater than 1MB.

i would double all specified params (leave Survivor alone) until maxheap -Xmx 
reaches AvailablePhysicalRam/2
2)you've maxed out HW RAM
at which point I'd run down to local tech supply store and buy more RAM sticks 
(good to wait for offhours
,down the server and take one of the ram sticks with you just to make sure you 
have a good fit..generally safe to double..if you have 1 get another..if you 
have 2 get 2 more )

(unless of course this is a unisys box then i would ask Unisys)

RE: Just a few questions on my Tomcat Configuration

 From: Josh Gooding [mailto:josh.good...@gmail.com]
 Subject: Re: Just a few questions on my Tomcat Configuration

 I use virtual hosting to create /abcapps and /xyzapps and install the
 program in each directory.

The proper term is webapp, not program.  A webapp has a spec-defined 
directory structure that must be adhered to for proper operation of the webapp. 
 Browse through the various webapps that come with Tomcat to get an idea of the 
layout, read the servlet spec for the details.

 In the Host section, bind the sub-domain to them

Also set the appBase attribute of each Host to point to the specific 
sub-domain directories.  Note that the default webapp for a Host must be 
named ROOT (case sensitive).  One of your Host elements must be declared as 
the defaultHost for the surrounding Engine; this is the one used when the URL 
does not match any of the Host name attributes (including references via IP 
address).

 then I should be able to login per subdomain

Depends on what you mean by login.  If it's just accessing the web site, yes; 
if you mean authentication, you'll need to configure the appropriate security 
mechanism.  This is usually done with a Realm, which can be placed inside an 
Engine, Host, or Context, as needed.

 (since I have files being uploaded to the server).

Do not attempt to write files into the appBase directory - keep them outside of 
Tomcat's directory structure.

 It's all housed in the Server.xml file right?

Context elements are not.  (Watch out for your capitalization; many file 
names are case-sensitive, even on Windows.  That should be server.xml, not 
Server.xml.)

 One more quick note, is there a way that I can break out certain
 sections of the server.xml file into a seperate .properties file?

Not that I'm aware of, although various XML inclusion mechanisms might work 
(haven't tried).  You can resolve attribute values from system properties, 
using the ${prop.name} notation.  Anything to do with specific webapps should 
not be in server.xml.

 can I do the same thing in the server.xml file since it is 
 a core file that tomcat relies on for it's configuration?

And is thus not intended to be updated frequently.  The contents of server.xml 
are only read when Tomcat starts up; changes mad after the fact won't be 
honored until the next Tomcat restart.

File descriptor exhaustion - the process has run out of fds.  Any i/o could use 
a file descriptor, whether that's socket to httpd, socket to database or access 
to a file.  Naively, I'd expect lsof to show them - what makes you think it

If you're lucky, you merely need to find the piece of code that's leaking 
resources and fix it - which I accept isn't always the easiest of jobs.  If 
you're *un*lucky, it's load related and you've just plain run out.  I'll leave

tomcat-connectors mod_jk.dsp file will not load in Visual Studio 2005

2009-06-03 Thread Andy Wang


Hi all,
I was able to get mod_jk building fine using Makefile.vc, but couldn't 
get the .dsp file loaded into Visual Studio 2005.  Anyone know if 
there's a trick to this, or should I just not care (it does build and 
seem to work fine with the Makefile).


When Visual Studio 2005 tries to convert mod_jk.dsp to the newer format 
it complains with a

Cannot load the project due to a corrupt project file

popup.

Does anyone really care about this or should I just ignore it?

Thanks,
Andy

If you have multiple tomcats and multiple applications then 
you have to put the jars on a separate location

As Peter pointed out, doing so is a really bad idea.  The OP should continue to 
run what's working, with the jars duplicated in each webapp's WEB-INF/lib 
directory.  Anything else is extremely problematic.

Yeah, I once tried having a single lib location for the common jars, and 
while I could get it working, it was quite fragile, and I ended up 
giving each webapp its own copy of the libraries in question.  It's been 
much more robust since then.

Understanding GC Logs

2009-06-03 Thread CrystalCracker


I am just trying to learn and understand the GC logs. (I did read the sun's
docs on GC tuning).

jdk1.6.0_07
-Xms2g -Xmx2g -Xss256k 
-XX:+UseLargePages -XX:+PrintGCDetails 
-verbose:gc -Xloggc:/var/log/gc.log 
-XX:PermSize=512m -XX:MaxPermSize=512m

It is running Parallel Collector by default. The full GC usually runs in
every 20-30 minutes (takes 2 seconds), and the minor collections occur every
40-50 seconds. I viewed the logs in GC Viewer, and the throughput is about
99.6%, but the pauses tend to get noticable at times slowing the app down
for upto 10 minutes- and sometimes the app becomes unresponsive after
running for about a week due to GC. 

I have pasted the snipped from my GC logs (when the pause became
noticeable). Does the logs in themselves indicates any possible problems?
Thanks in advance.

Re: Blank page when native DLL used

2009-06-03 Thread Frank W. Zammetti


Hi Chuck,

Nope, I just verified, I made no changes to server.xml at all... in 
fact, the only thing I did do was take all the preinstalled applications 
and remove them from webapps... I'd be surprised to learn it, but could 
that be the problem somehow?


Thanks,
Frank

32-bit, and I re-confirmed I have the right download (which seems
obvious anyway given that Tomcat picks it up and starts running 
with it, but you never know).



You didn't happen to disable the APR listener in server.xml, did you?  That 
might contribute to the observed symptoms.

Including ROOT?  If you don't have a default webapp deployed, you will get a 
blank page back if the URL can't be matched against any of the deployed 
webapps.  (This is true with and without tcnative-1.dll available.)  Note that 
the browser may display an old copy of the Tomcat home page if it has one lying 
around; hitting refresh will get rid of that.

Re: Blank page when native DLL used

2009-06-03 Thread Frank W. Zammetti

That's correct, root too... I tried adding all the webapps back in 
anyway to no avail... the URL I know is correct because without the DLL, 
it gets me my page as expected, but when I drop the DLL in and just hit 
refresh, I get the blank page (I also confirmed there was no trailing 
slash both times to be extra sure).  I can of course hit refresh all day 
long without the DLL (the JSP renders the current time so I know it's 
properly being refreshed).


Well, if I'm the only one that's ever reported this then no big deal, 
I'm perfectly happy assuming it's something on my machine (or me doing 
something stupid that I just can't catch).  This is just for development 
so not a problem at all.  If others see this though, maybe then it might 
be indicative of an actual problem.


Take care,
Frank
