Hi there,

I have a WAR which normally should be deployed via myName.xml into
/tomcat/conf/Catalina/localhost, with docBase=AbsolutePathToWar.

Within that xml snippet, Context path=/myName

So I can call www.server.com/myName and it works.

Now I want to call myName.server.com instead.


This would mean that your webapp becomes the ROOT application of a 
virtual host.



I have tried to remove myName.xml from /tomcat/conf/Catalina/localhost and
added the following snippet within server.xml:

Host appBase=webapps name=myName.server.com  Context path=
docBase=/webs/web123/tomcat/application.war debug=0 ...

But it doesn't work, the application got undeployed (empty dirs), I even
deleted the empty dirs and restarted tomcat, nothing (seems as if tomcat
doesn't care about the context at all)...

I definitely want to run the application from the WAR (for upgrading
reasons), and the WAR definitely should NOT be put into the webapps
directory to get deployed (as it worked with the myName.xml deployment).


As you didn't specify which version of Tomcat, I'm going to assume 5.x.
Place the context here:

%TOMCAT/conf/Catalina/myName.server.com/ROOT.xml

... not in server.xml.


How to configure this?!

Thanks in advance
Detlev

Re: Install WAR via docBase within servlet.xml

Ahhh, that sounds as if would make sense... :-)

But the HOST entry for the virtual host would have to be in server.xml (with no

java.security.AccessControlException: access denied
(java.io.FilePermission 
/var/lib/tomcat5.5/webapps/blog/WEB-INF/classes/META-INF/hivemodule.xml

read)

This line (above) would indicate you have the security manager running.  
To fix this, you'll need to adjust conf/catalina.policy to allow read 
access to the file.  The OS's file permissions are probably fine.  As an 
aside, META-INF is typically a special folder in jar and war files -- 
you probably rename this META-INF to something else if for no other 
reason than to remove some potential confusion.

Why did you do this? Unless you have a /really/ good reason, all of the

Nobody seems to believe us whenever we say classes loaded by one
classloader cannot see classes loaded by another (unrelated)
classloader. It's true!

The commons-logging classes are loaded by one of the server's
classloaders (because you have them in $CATALINA_HOME/lib or whatever).
The log4j classes are loaded by your webapp's classloader (because they
are in $YOUR_APP/WEB-INF/lib). Therefore, commons-logging cannot create
instances of the log4j classes loaded by that other classloader.

The Tomcat 6 Logging page
(http://tomcat.apache.org/tomcat-6.0-doc/logging.html) lays these steps
out quite clearly:

1. Put a log4j.properties file in $CATALINA_HOME/lib.
2. Download Log4J (v1.2 or later) and place the log4j jar in
$CATALINA_HOME/lib.
3. Build the commons-logging additional component using the extras.xml
Ant build script which is part of teh Tomcat source bundle.
4. Replace $CATALINA_HOME/bin/tomcat-juli.jar with
output/extras/tomcat-juli.jar.
5. Place output/extras/tomcat-juli-adapters.jar in $CATALINA_HOME/lib.
6. Start Tomcat

You are missing (at least) step 2.

The good news is that since your log4j.jar file is in
$CATALINA_HOME/lib, you can also use log4j in your webapp (which is
probably what you want anyway).

For more information on where Tomcat loads which classes from where, and
what the relationship of the classloaders is, see the TC Classloader
Howto: http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html

Questions about Tomcat installation on Solaris Platform

2007-02-06 Thread Chittajalu, Ravi S.

Hello Users Group, 

Request your help on following questions

1. This one is more a clarification question. 
I used a Unix account 'devuser', which is not
associated  to any Unix group. I installed Tomcat
using this user account. I was able to
successfully install and Tomcat runs fine. With
the same user I am not able to execute any  Java
program. I get an
Exception in thread main
java.lang.NoClassDefFoundError: TestDB . The program
compiles well, but cannot execute. My question is how is
Tomcat able to Run under the same User account 'devuser'??

2. I configured a Database resource name with JNDI name
jdbc/oracle10g, but I do not have a way to test and it
does not look like the connection is happening.
I gave the 
 URL :jdbc:oracle:oci:@host:port:SID
Driver as: oracle.jdbc.driver.OracleDriver
Then userid / password.

I tested the SID from unix command line using
SQLPLUS and it works.
Can some suggest a way to test this and If there
is any  problem with the configuration.

Regards
Ravi Chittajalu

If you're sure the connection data is good, then it's configuration --
you'll need to provide the relevant parts of your config files.

Large number of active sessions

2007-02-06 Thread Christer Nordvik


Hi!

I've got a website with pretty low traffic (200 visitors a day). Lately it's
been very slow and when I look in Tomcat's manager it says that it has a lot
of sessions.
Once I had 13000(!) active sessions. The session timeout is set to 30
minutes.

How can this happen? Isn't this something that Tomcat should handle itself?
Can it be related to my code somehow? I have only basic JSP/Servlet stuff so
nothing fancy going on.

Any help would be very appreciated!

-Christer

Re: Large number of active sessions


1) Lower your session timeout.
2) How are you measuring/calculating statistics?
3) Which version of Tomcat?
4) Are you url encoding all of your links?

Re: Large number of active sessions

2007-02-06 Thread David Wall

It seems that Tomcat 5.5.17 (and earlier) has had some sort of problem 
in timing out sessions.  I'm not sure if it would clean itself up if the 
person really came back and did another HTTP transaction or not, but 
I've noted that Tomcat Manager will show sessions that are have been 
idle much longer than the session timeout value (based on the last 
access timestamp in the session).


Our application also has a registered listener HttpSessionListener and 
we've seen that these old sessions do not trigger that callback either 
as we also list the session as active.


As for suggestion (1), this won't matter and 30 minutes is the default.

As for suggestion (4), this could clearly create extra sessions for 
those few who don't allow session cookies, but even those sessions 
should time out.

Re: Large number of active sessions

2007-02-06 Thread Rashmi Rubdi

You can also activate server logs to log both visitor and bot activity by 
configuring AccessLogValve : 
http://tomcat.apache.org/tomcat-5.0-doc/config/valve.html . 

Some bots take up a lot of sessions, you can verfiy this by running a program 
like Xenu Link Sleuth on your site.

Then, you will be able to block certain bots by IP address or User Agent string.

I think it's still in 5.5.20, if this is the one you're talking about:
http://issues.apache.org/bugzilla/show_bug.cgi?id=37356

I don't think this would be triggered, though, unless you had heavy load
on the sessions themselves.

Session Affinity and Session Replication

Hello All,

I'm trying to get a better understanding when to use Session Affinity and 
Session Replication and have a question. Let me set my question up by 
describing my configuration. It consists of an Apache server with mod_jk and 
two Tomcat servers, where the Apache server is configured to load-balance 
between the two Tomcat servers. So my question is, if I enable session affinity 
but not session replication, how can I failover a connection without losing the 
session data?

Let me restate my question more like a use case:

  - Given the above configuration of Apache and 2 Tomcat servers

  - A session has already been started on Tomcat-1 (session contains data)

  - A new request comes in with the same session id. Session affinity is on 
so the request should go to Tomcat-1. But Tomcat-1 is down so the request fails 
over to Tomcat-2.

  - Since session replication is not enabled how does Tomcat-2 get the 
session data? Or can it?


Can this problem be solved by using both sticky sessions and session 
replication? Or do I have to abandon session affinity and just use session 
replication. All the documentation I've read to date indicates not to use 
sticky sessions and session replication together.


Thanks,
Rob

You can't, unless you are using some other mechanism to share that data.

Many times, losing a session isn't a big deal if there's not too much
information held only in the session.

 - Since session replication is not enabled how does Tomcat-2 get the

Tomcat-2 has to start over with a new session (i.e. there's no
recovery). In order to share sessions between servers, you must have
session replication enabled.

 Can this problem be solved by using both sticky sessions and session 
 replication?

That's generally the idea.

 Or do I have to abandon session affinity and just use session
 replication. All the documentation I've read to date indicates not to
 use sticky sessions and session replication together.

What have you been reading? I've never done either of these, but it
would seem that the two in concert is the best solution.

context placement

I am trying to use tomcat 5.5 for the first time - having just moved 
from tomcat5.

I am getting symptoms (I think) of my JDNI resource having not been set 
up properly

In particular, I have NO contexts in my $CATALINA_HOME/conf/server.xml, 
since I want to bring these in in my webapps .war file.

So in the .war file for my app I have a META-INF/context.xml file with 
the following in (apart from the password which I have changed)

?xml version=1.0 encoding=UTF-8?
Context docBase=usermgr path=/usermgr
Resource name =jdbc/usermgr auth=Container 
type=javax.sql.DataSource
driverClassName=org.postgresql.Driver 
url=jdbc:postgresql://127.0.0.1:5432/users
username=tomcat password=x
maxActive=20 maxIdle=10 maxWait=-1 /
/Context

and my application attempts to connect to the JDNI resource

java:/comp/env/jdbc/usermgr

But when I run it, I get the following in the error message

Cause: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC 
driver of class '' for connect URL 'null'


I am interpreting this as the JDNI resource has not been recognised.

Do I have the right interpretation?
Have I misunderstood how tomcat can find the contexts?

Steve,

This might be off-topic, but there's really not a good forum for
general webapp what-the-heck-is-going-on discussion. But hey, we're
nice folks ;)

Okay.

 I am attempting to create a report that will return all instances 
 where a person has not been assigned to a case.  There is nothing in
  the database in any fields that the NO ASSIGNMENT phrase is related
  to

This is not surprising. I'll bet that the code looks for an assignment
and, finding none, displays this message.

 I have been trying to track down within the code for the web page 
 where this NO ASSIGNMENT phrase is coming from in hopes of 
 understanding how the application knows to return this statement.  My
  theory is that if I can see how the application is returning this I 
 can figure out how to query the database to show me all instances 
 where this has occurred.

This sounds reasonable. Unfortunately, web application can grow to
significant complexity, and sometimes things like strings displayed in a
page can come from unlikely sources. Are you familiar with Java at all?
That might be helpful for your forensic reconstruction, here.

 Can someone give me some direction on where I can search for this 
 type of code?

Well, it's unlikely that the phrase NO ASSIGNMENT will appear in any
of your Java source code (that is, files with the .java extension).
You're more likely to find it in either a JSP file (ending in .jsp) or
in a properties file (ending in .properties).

You can search everything on a UNIX system using something similar to
the following:

$ grep -l NO ASSIGNMENT `find /path/to/application -type f`

(Note the use of back ticks).

This will display a list of files that contain that phrase.

 a 
 href=/occa/model.do?model=oscn.seq.prompt-Assignmentamp;assignType=1a
  mp;data=95972amp;caseMasterId=95972 NO ASSIGNMENT/a

Can you determine which file generated this output? Usually Java web
applications will use JSP or some other technology to generate the
actual HTML that the user sees. By locating the file that generates this
output, you can probably figure out how the decision is made that there
is no judicial assignment.

Otherwise, you'll have to start searching through code and basically
backtrack through the process.

I can probably take a stab at a query that might work. You mentioned
that you have tables like this (well, I'm guessing for most of this)

CASE
- 
id

ASSIGN
- --
case_id  (points to case.id?)
id   (points to assignee.id?)

If an assigned case has a record in the ASSIGN table, then an unassigned
case would probably have /no/ records in the ASSIGN table.

You could find those cases using a query like this:

SELECT case.id
FROM case
 LEFT OUTER JOIN assign ON assign.case_id=case.id
WHERE assign.id IS NULL

This should pull all CASE records who have no matching ASSIGN records in
the database.

Just a thought, but I have /no/ idea how your database is laid out or if
there's a better way to do this.

 If this question is better answered outside the Tomcat community
 please let me know and I will not waste your time any further.  Thank
 you in advance for any assistance you can provide.

This list typically deals with Tomcat-specific issues, but, as I said,
there's no really good forum for asking for this type of thing. Just
leave OT in the subject line and you'll generally be forgiven ;)

Get rid of docBase and path. I believe they are illegal in a
context.xml file, since the server has already determined where your
application is and to what URL it will be deployed. It is rumored to be
bad to set these attributes in context.xml. It might even cause Tomcat
to double-deploy (or worse, double-deploy on top of each other) your
webapp and cause great confusion.

The rest of this looks good, and matches the configuration I use for my
webapps.

Yup, this is going to be a subtle configuration error. Make the changes
I suggested above and see if that helps. If not, do a quick search in
the archives for cannot create jdbc driver null: this question comes
up occasionally.

Ah, OK -- perhaps that's JK-specific. As I said, I used mod_proxy_ajp
which has no worker configuration to it. In fact, having used mod_jk
in the distant past, I was impressed by the simplicity of configuration
of the mod_proxy_ajp setup. Might be worth a look :-)

Load Balancing Configuration


Hello All,

I currently have the following load balancing configuration: Apache with mod_jk 
and 2 Tomcat servers and Apache acts as the load balancer for the two Tomcat 
servers. I'm concerned about the single point of failure with Apache, however. 
Is there an alternate configuration that, for instance, allows me to have more 
than one Apache server balancing the Tomcat servers?

Thanks,
Rob

Guess I have to go the long way of creating my own session listener then,

If you /need/ real-time redundancy/failover, you want dedicated load
balancer hardware.

If your budget doesn't cover that, here's the bargain way(tm):

Set up two servers with Apache httpd, call 'em X and Y.

X is configured with the Web server's public IP address. A cron job on
Y pings or gets a test page every N seconds from X.

If that fails (or depending on how trigger-happy you want to be, fails
for some # of attempts) then the cron job on Y ifconfigs the box to
respond to the IP of X.

(You can criss-cross this if you're using round-robin-DNS.)

Hacky zero-dollar failover, and duct tape left over :-)

Re: webapp, ServletContextListener and log files

2007-02-06 Thread Hugues Ferland

I apologize for this previous mail, I realized this was just plain wrong. It 
was stdout and stderr that was written to catalina_.log (though I don't 
know where that log file is configured - there is also a catalina.out which 
remains empty).

This lead me ask: What Context  swallowOutput=... really do? As I 
understood it, it was supposed to indicate to Tomcat whether it should smallow 
stdout and stderr and write them to its log file. But I tried both true and 
false with no apparent difference.

Thanks,

Hugues

I use Tomcat 5.5 with Java 1.6.0-b105 on a Debian Linux.

I have a context defined and want all of its logging to be in its own logfile. 
The first thing I tried is to modify the file logging.properties, in the conf 
directory of my Tomcat installation, adding a handler for my new context.

This looked good until I added a ServletContextListener. Now what is logged 
during the execution of the method contextInitialized, is written to  
catalina_.log (the logfile defined in the Tomcat startup script).

I'd like that to be logged in the same logfile as the rest of the context. I 
would really appreciate any help.

Thanks,

Hugues

 I have to say that your recommended query was the advice that helped

 what I needed to jumpstart my brain.

Well, just make sure that I know what I'm talking about. You gave very
few details about the structure of your database. I don't want to have
given you completely incorrect advice... based upon database schemas and
possible foreign keys, etc. you ought to be able to piece together what
it means to have no assignment and then simply rely on the database to
determine that.

Your webapp is likely doing the same thing, just with much more
complexity (since that notion probably goes through at least one level
of data objects and some type of HTML generation).

 When I
 wrote the SQL query in the MySQL Query Browser (with the appropriate
 table names of course) I got the returns I needed.

So, CR is being a pain in your neck? Try a simpler query. Perhaps CR is
trying to do too many thing automatically (such as interpreting the use
of LEFT OUTER JOIN) and you need to help it along a little more.

Good luck,

Tomcat policy file, advice and clarification please

2007-02-06 Thread Hugues Ferland

Hi,

I have a Tomcat 5.5 installation on Debian Linux with Java 1.6.

I have a web application that create its own connection to an Oracle database. 
The ojdbc14.jar is included in the WEB-INF/lib directory of the web application.

Now with the default configuration with security enabled, a SecurityException 
java.lang.RuntimePermission getClassLoader is thrown.

I tried to apply a security policy to ojdbc14.jar with grant AllPermission, but 
without success. This is what I added to /etc/tomcat5.5/policy.d/50user.policy:

grant codeBase file:/the path to the web application/WEB-INF/lib/ojdbc.jar {
   permission java.security.AllPermission;
}

This did not work. One particularity of the web application is that I do not 
deploy it with a war file. I created it using a context xml file in 
${catalina.home}/conf/Catalina/localhost/context name.xml.

Also the docBase point outside the ${catalina.home}.

Of course, I'd like to know what I'm doing wrong... I looked on google, 
tomcat-docs, and other places without any luck... Maybe somebody could point me 
in the right direction? Or better yet tell me what is wrong :)

Thanks,

Hugues

 Mark,
 
 Is there a changelog available for the 4.1 line? I can't seem to find it
 on the website, using the search, or even googling for tomcat 4.1
 changelog. All of the more recent lines (5.0, 5.5, etc.) seem to have
 easily-findable changelogs.

It is in the release notes. The version in svn is up to date and
available from

2007-02-06 Thread 吳金能


Dear all

I want to confirm one thing that Tomcat only can provide SSL encryption 
serverice with sign-self certificate ?

Because i have tried SSL with certificate signed by our own CA, Tomcat would 
not work and occured SSL handshake Exception.

 Subject: Re: Session Affinity and Session Replication

 Thanks, for the information. My confusion in part stems from this comment
 in the The Apache Tomcat Connector - Reference Guide,
 http://tomcat.apache.org/connectors-doc/reference/workers.html

 In the comments for sticky_session: ... Set sticky_session to False when
 Tomcat is using a Session Manager which can persist session data across
 multiple instances of Tomcat Also, I've seen other comments in this
 mailing list that would indicate not to use both at the same time.

If session replication is on, and synchronous (the replication completes
prior to the request completing) then you do not need session affinity as
all cluster members will have the up-to-date session data.

If you use an asynchronous mechanism for replication, you will slightly
improve your response time, but at the possible cost of the next request
coming to a different cluster member which is not yet up-to-date.

Combining affinity and replication gives the session a preferred server,
with seamless failover.

Not only does it work, but it works really, really well.  I have been using
it in a production site now for almost a year, with one Apache+mod_jk, and
three Tomcats.  You can shut down one Tomcat for maintenance, bring it up,
and shut down the next, etc., and nobody is ever the wiser.

Tim

 Rob

 Can you cite where you saw that?

 I've set up a similar config (using mod_proxy_ajp) with both sticky
 sessions and session replication and it worked fine.
