Re: Query related to detection of the Source IP Address in Load-balancing mode

1) have a tomcat instance, containing config directory. This would
have catalina/demo1.company.com/ROOT.xml containing pertinent jndi

Sounds good.
2) in server.xml add this

directory=logs prefix=demo_access_log. suffix=.log
pattern=%h %l %u %t quot;%rquot; %s %b resolveHosts=false/
/Host
Well, that will give you an access log for the whole host. If that's
what you want, that's what you got. If you want the webapps to have
separate access logs, you'll have to configure the Valve in ROOT.xml
(and whatever other webapps you deploy). Maybe something like
ROOT-access as the prefix value.
When I start the app, it works and the app works. However all
context's apps log to the same log file. What I want to know how to
make the different contexts under different hosts log to different

appender name=FILE
class=org.apache.log4j.rolling.RollingFileAppender param
name=Threshold value=INFO / param name=File
value=${catalina.base}/logs/demo.log /
So, this is a different issue. Above, you had an access log, which
logs the hosts and URLs that they request, etc.
It appears that log4j is an application log, like for INFO and DEBUG
and stuff like that, right?
Well, the obvious solution is to change the value of the File
parameter in your log4j configuration. Try using something like
ROOT-demo.log and a different value in the config file for the other
copies that you deploy. Of course, that means that you can't actually
use the same WAR file, or you need to figure out some way to load the
log4j configuration file from another location.
If you write your own ServletContextListener to load the log4j
configuration (that's what we do over here... it also shuts-down log4j
when the webapp undeploys), then you ought to be able to use the JNDI
context to find the location of a configuration file on a per-context
basis. For instance, you could put your config files somewhere like
/etc/mywebapp/ROOT.xml and /etc/mywebapp/non-root.xml and just change
the name of the log file name.

I'm afraid I don't know a thing about JNDI context selectors and
log4j. Sorry.
I have tried to add a suitable web.xml environment entry, and then

Yeah, that doesn't work because it doesn't set a system property,
which is what log4j requires for that kind of replacement.
You could just run separate instances of Tomcat. It would be less

Re: Connection pooling issue with MySQLNonTransientConnectionException and Java webapp
On 21 Nov 2011, at 09:28, app...@dsl.pipex.com app...@dsl.pipex.com wrote:
Hello
I don't think this is a Tomcat issue but I thought I would post here just in
case.
I have a Java, JSP and MySQL application running under Apache Tomcat 6.0.26
which I've been testing with JMeter.
What I find is that for a simple test having 10 users logging in and
displaying a JSP which is populated from
several database reads, everything is fine.
But when I increase the number of users in JMeter to 20+, logging in starts
to fail with HTTP request 500. Checking
the logs I find that I am getting large numbers of
MySQLNonTransientConnectionExceptions as follows:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could
not create connection to database
server. Attempted reconnect 3 times. Giving up.
So this indicates that there's an issue either with the connection pooling
through Apache Tomcat 6.0.26 or MySQL
Community Server 5.X.
The relevant part of the application's context.xml file in the project reads
as follows:
Resource auth=Container driverClassName=com.mysql.jdbc.Driver
logAbandoned=true maxActive=-1 maxIdle=30
maxWait=1 minEvictableIdleTimeMillis=3
name=jdbc/myApp numTestsPerEvictionRun=5
password=XX removeAbandoned=true
removeAbandonedTimeout=120 testOnBorrow=true
testOnReturn=false testWhileIdle=true
timeBetweenEvictionRunsMillis=-1
type=javax.sql.DataSource
url=jdbc:mysql://localhost:3306/myApp?autoReconnect=true
username=XX validationQuery=select 1/
I've set maxActive above to -1 on the understanding that this is unlimited. I
think that the MySQL error is because
MySQL is refusing the connections.
Am I correct here? Can anyone suggest a workaround or advise?
Typically, my database operations are as follows:
// Gets an ArrayList of Datasets.
public static ArrayListDataset getDatasets() {
ConnectionPool_DB pool = ConnectionPool_DB.getInstance();
Connection connection = pool.getConnection();
Usually the connection is initialised as null and then assigned inside
the try block. What happens if the method above throws an error after
a connection is removed from the pool?
p
PreparedStatement ps = null;
ResultSet rs = null;
String query = (SELECT * +
FROM Dataset +
WHERE Active = ' + Valid.TRUE + ';);
try {
ps = connection.prepareStatement(query);
rs = ps.executeQuery();
ArrayListDataset datasets = new ArrayListDataset();
while (rs.next()) {
datasets.add(mapDataset(rs));
}
return datasets;
}
catch(Exception ex) {
logger.error(Error getting list of Datasets\n, ex);
return null;
}
finally {
Database_Utils.closeResultSet(rs);
Database_Utils.closeStatement(ps);
pool.freeConnection(connection);
}
}
And there can be quite a few of these per page.

I might file an enhancement request for Tomcat... If you have already done it, can I vote it for? If I add my own script containing /etc/init.d/tomcat restart to the crontab I loose the user sessions and users have to relogin. Yes... because you restarted the server! As Chris Schultz wrote it is possible to persist sessions over tomcat restarts. I chagned my session objects to be serializable and It works. I experience some problems with OutOfMemory error. Wouldn't it be better to understand and fix the OOM, rather than just rebooting the server frequently? Yes, it is allways better to solve the cause than the consequence of a problem. But not allways man can have enough time or means to solve it. When an error occurs at production it is better to setup some kind of recovery (eg. recycling) and than solve it at pre-production / devel environment. You can use a third party lib with an error. Particulary in my case, my app consists of a one single cycle where I download a CRL, parse it using BouncyCastle lib and retrieve serial numbers of revoked certificates. So the problem can rather in third party lib than in my small piece of code. I've tried to profile memory consuption but have not found out nothing. Maybe I had had not enough memory for java virtual machine. I've set it from 128 MB to 512 MB and the problem have not occured yet. On tomcat I run a periodic thread that downloads CRLs and I suspect this of memory leaks. Why? Can't you fix that? If we forget the OOM exception, I was forced to make a ShutDownHook. I use spring quartz scheduler and my job can run quite a long time. So I had to add some notification to stop job correctly. Tomcat was complainting about possible memory leaks when ending quartz job-worker threads when I was stopping app for redeploy my app. Yes, Tomcat is helping you by warning you about a potential problem. The last time I looked at Quartz the shutdown process didn't actually wait for threads to finish before returning. I had a little success with Thread.yield() but I suspect that it would not be effective for multiple jobs or a longer process. In a single process model (crontab) I could afford to kill -9 the process and I could rely on transactionality in the database which I'm using. I'm not sure how that relates to this discussion. At the end I'd like to make a little comparision. Recently I've used .NET + native calls of dlls, php + custom made php modules (native dlls), jsp+java. .NET and php have possibilities for some kind of recoveries. I'm not sure what that means. It's almost imposible to crash Apache like a whole (control + x worker processes). So .NET and php seems me they're more stable than tomcat because they have some possibilites. I completely disagree. You're comparing two languages with an application server, for a start. I haven't studied recovery options in other java app. servers, but I'd really appriciate something in Tomcat. I think the harm this function would do would outweigh any perceived benefits.

Re: where to put static files?
On 21 Nov 2011, at 18:52, André Warnier a...@ice-sa.com wrote:
Hi.
What we are trying to say is this :
The WEB-INF and META-INF sub-directories of a Tomcat webapp, are supposed to
contain files
that should NOT be accessed by the users. For example, in the WEB-INF and
META-INF
subdirectories, there are files (like WEB-INF/web.xml) which may contain
private
information (such as, e.g., passwords to access a database system).
For that reason, Tomcat itself forbids access to the content of these
directories.
If you try to access Tomcat directly via a URL like
http://myhost.company.com/mywebapp/WEB-INF/somefile;, you will get a
Forbidden
response. Always.
But if on the same host, you run another webserver (Apache, nginx,..), and
you allow this
webserver to access the content of the Tomcat ../webapps/mywebapp/WEB-INF
directory, then
you bypass the Tomcat security and make it useless.
That means that a user, with a well-crafted URL, will be able to access and
display the
content of those files. This is a big security hole.
You can configure the front-end webserver to also forbid this, but it
requires additional
configuration, and you will forget to do it, or do it wrong.
So don't do that.
Tomcat will server static resources just fine, usually as fast as Apache or
nginx would.
If you insist that you must serve this static content directly from the
front-end
webserver, and not ask Tomcat to do it, then place them somewhere under the
DocumentRoot
of the front-end webserver (which should /NOT/ be the same as the Tomcat
webapps
directory), and use the proxy instructions so that these requests are /not/
forwarded to
Tomcat, but served locally.
+1. I would use stronger terms: never allow DocumentRoot and
tomcat/webapps to overlap.
p
For example :
ProxyPass /mywebapp/images !
ProxyPass /mywebapp/css !
ProxyPass /mywebapp ajp://tomcat:8009/mywebapp
will proxy all requests for /mywebapp to Tomcat, *except* for the /images and
/css
subdirectories.

If you are using httpd for something useful (and just serving static content isn't one of those things), then most people connect Tomcat to it via mod_jk or mod_proxy_ajp. If you have no specific need for httpd, then use Tomcat directly and avoid the complexity and performance impact. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Auto-size or select-at-startup? I thought the latter, and that in worker mpm it derived from ThreadsPerChild. At least that's how I read the docs Mladen / Rainer's previous statements on the topic. Obviously, in the prefork MPM, it defaults to 1 because you simple can't make more than one connection. For the worker MPM, I think the default is one connection per thread (per worker, of course), so if you have 600 total threads, you'll have 600 threads * 20 connections each = 12000. Right... but if MaxClients is 600 that's a lot of unused open connections, no? You can, of course, limit the number of connections by setting connection_pool_size to something smaller than the total number of threads * Tomcats you have. You'd only really want to do that if you were expecting a lot of requests to be handled directly by httpd with no communication with Tomcat. If you have 10% of your traffic going to Tomcat, then you might want to have your connection_pool_size set to 60 instead of (defaulting to) 600. I thought it defaults to 60 but becomes 600 in total because there are 10 pools, one for each worker. If MaxClients is still 600 and there is one Tomcat, one might assume that allowing all 600 to go to that Tomcat is sensible - but if there are two Tomcats, what is the behaviour? NB 600 to each Tomcat would be more than MaxClients. mod_jk isn't affected by MaxClients, of course (aside from possibly the auto-default of connection_pool_size). Correct, but if MaxClients is 600, what's the point of having more connections open to the backend Tomcat(s)? If you have 600 worker threads and 1 Tomcat, I would expect 600 persistent connections from httpd to that one Tomcat instance. Doubling the number of Tomcat instances (by adjusting the worker, for example, to be an lb) will result in doubling the number of backend connections to 1200. If you have more than one worker, then the number of Tomcat instances is essentially multiplied. So, if you have 20 TC backends each with 2 workers assigned to them, then you'll 24000 connections instead. Will this change If Tomcat instances start failing? Probably not -- mod_jk will just retire the connection and create a new one. If you are having load problems, you might make things worse with all this connection churn. Agreed. So, what was the problem you were trying to solve in the first place? I saw behaviour I didn't expect at a customer. Made more complicated by other factors, so I wanted to clarify the expected behaviour. Or, was this a capacity-planning Gedankenexperiment? - -chris PS Missed you (again) at ApacheCon.

If ThreadsPerChild is 60 and ServerLimit is 10, MaxClients is 600, how many connections, at peak, will be made to 20 Tomcat instances? - From httpd docs: MaxClients: For threaded and hybrid servers (e.g. beos or worker) MaxClients restricts the total number of threads that will be available to serve clients. The default value for beos is 50. For hybrid MPMs the default value is 16 (ServerLimit) multiplied by the value of 25 (ThreadsPerChild). Therefore, to increase MaxClients to a value that requires more than 16 processes, you must also raise ServerLimit. ServerLimit: With worker use this directive only if your MaxClients and ThreadsPerChild settings require more than 16 server processes (default). Do not set the value of this directive any higher than the number of server processes required by what you may want for MaxClients and ThreadsPerChild. So if MaxClients is 600 and ThreadsPerChild is 60 then you can't have more than 10 processes each with 60 threads. If you want more than 16 server processes (which it looks like you don't need), then you'll need to set ServerLimit to something higher than it's default for worker which appears to be 16. I'm not sure you need ServerLimit at all. If you have 20 TCs on the back end, then mod_jk will have to open 20 * 600 = 12000 connections at peak, if my math is correct. That's only 600 connections per TC, or course, but you may have trouble with creating that many connections from the proxy. What I'm not clear on is whether the mod_jk worker connection_pool_size is 60 per Server child, or 60 * 10 Server children. If MaxClients is still 600 and there is one Tomcat, one might assume that allowing all 600 to go to that Tomcat is sensible - but if there are two Tomcats, what is the behaviour? NB 600 to each Tomcat would be more than MaxClients. If you have more than one worker, then the number of Tomcat instances is essentially multiplied.

Is that correct?
You state that you want to eliminate Level 2.
However, from a performance standpoint, why would you? Without the Level 2
balancing, it is conceivable that one of the 3 Tomcats could end up
processing the bulk the JSP requests.
Why?

However, Pid is correct. If you are worried about performance, you could drop
the HTTPD servers and balance directly to the Tomcat servers. Tomcat is just
as fast at delivering static content as HTTPD, and it simplifies deployment.

Subject: AW: mod_jk Avoid loadbalancing
Hello,
Yes, it was an option to solve my problem. But what about the
performance?
My opinion was to forward only necessary requests to the Tomcat (jsp,
java
etc) and let the Apache HTTPD deliver the static content (CSS,JS,Images
etc).

Please don't top-post. No-one can really answer the question you have asked, we don't know enough about your application or how much memory it needs to use. We can only advise you to avoid bad configuration. Trying to assign 2Gb to a Java process if the OS only has 0.5Gb free beforehand is bad configuration. And maths, it's also Bad Maths. If you use JAVA_OPTS to set memory config, (as below), you will create a JVM instance with 2Gb of RAM, if you are using the shutdown.sh script which will run as well as the existing Tomcat instance. Both processes will end up using the swap, be horribly slow probably OOM. If you use CATALINA_OPTS, these values are not applied during shutdown but are used during startup. You have 4Gb of physical RAM. The amount of memory you can use for Tomcat is the amount of free RAM when Tomcat is not running. If your server (without Tomcat) has 2Gb free, then Tomcat can use up to 2Gb. The -Xmx and -Xms settings apply to the Object Heap. The Object Heap is only one part of the memory that a Java process consumes. (The Non-Heap area includes the PermGen space, for example.) So, with 2Gb free RAM, you may be able to set -Xmx to 1.2Gb (this is a guess, not a hard rule). You will have to test it yourself to determine what is safe. Use VisualVM or JConsole (both are included with the JDK) to measure heap/non-heap usage and compare it to the amount that the OS says the process is using. p Pid * wrote: On 10/11/2011 22:45, Igor Cicimov wrote: JAVA_OPTS=-Xms2048M -Xmx2048M -XX:Permsize=512m -XX:MaxPermsize=512m You are allocating here 2.5GB of memory to tomcat ... how do you expect it to start on a box with 2GB in total of which only 500MB are available? +1 It's the perfect way to achieve shockingly bad performance. p On Fri, Nov 11, 2011 at 8:25 AM, Christopher Schultz ch...@christopherschultz.net wrote: Celtic, On 11/10/11 12:02 PM, celtic man wrote: So i have updated the setenv.sh with -Xms2048M -Xmx2048M -XX:Permsize=512m -XX:MaxPermsize=512m and restarted tomcat..

The two are not usually compatible. 'graceful' is found in Apache HTTPD: [the] signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately. There is no equivalent for Tomcat. The Commons Daemon found in tomcat/bin/commons-daemon-native.tar.gz provides a service wrapper and /etc/init.d/ type sample script which may be useful. Why do you need to schedule Tomcat restarts?

No, you are right.
What I meant is that I was/am managing session expiration inside the Webapp
(for instance if the user clicks a button which is inside the Webapp and if
the session has expired, I redirect him to the log in page).

A SOLUTION... I THINK.
I have found a solution, here it is:
for all the JSPs which require a user to be identified (*), I add the
following code:
Better solution is to check whether the user principle is set. The spec
will explain this.
%
ASessionAttribute aSessionAttribute = null;
HttpSession httpSession = null;
httpSession = request.getSession();
aSessionAttribute = (ASessionAttribute)
httpSession.getAttribute(aSessionAttribute);
if(aSessionAttribute == null)
{
response.sendRedirect(the-log-in-page.jsp);
}
%
Then if a user presses the F5 key and if the session has expired, he is
properly redirected to the log in page.

You'll have to provide more information, such as the code you are

I'm fairly sure Tomcat is not the source of the problem.
+1.
I think you need to pay more attention on the documentation of the
java.io.Reader#read() method, or maybe look for a tutorial.
See also documentation for java.io.InputStream#available().
In short: the read() method returns a portion of data that is
currently available. If you need more data you must call read()
repeatedly in a loop until it returns -1.
.. and the difference between two systems, may be that on one system, the
network is
faster (or the system slower, or the buffer bigger) and so by the time you do
the read,
there are more bytes available in the buffer.
If you had provided some of your source code that performs reading, we
would be able to point at the exact error in your code.

You'll certainly end up with both apps writing to the same file. Whether
or not that is a problem will depend on exactly how you have configured
logging.
Is it possible to pick up the name of the war file (or version number) so
that you can log to different files? So instead of
${catalina.base}\logs\myapp.txt
I could use
${catalina.base}\logs\myapp-${applicationName}.txt
say ${applicationName} which would be replaced with ROOT##001, making the
log file
catalina_base\logs\myapp-ROOT##001.log?
Basically I am trying to ask does such a variable exist, and if so what is
its name?
The catalina.base variable works because it's a system property.
There's no applicationName variable.

You have, say, 3 Tomcat servers running, and for the sake of the example let's say that these are - a Tomcat 5.x server - a Tomcat 6.x server - a Tomcat 7.x server You want to run the same applications on all of them (with identical names on each server), because for instance these are test servers serving to verify that a given application runs fine under each of these Tomcat versions. You want to be able to choose which Tomcat server you are accessing, by means of some URI prefix. Example : a request with URI http://myhost/tomcat7/webapp1; should be forwarded to webapp1 on Tomcat7, while a request with URI http://myhost/tomcat5/webapp1; should be forwarded to Tomcat5. Of course, once inside the respective Tomcat, you want this prefix to have been removed, so that the applications inside this Tomcat look similar to the same ones in other Tomcats, name-wise. Example : a request with URI http://myhost/tomcat7/webapp1; should be forwarded to webapp1 on Tomcat7, whith a request URI of /webapp1 (and not /tomcat7/webapp1). For this, you set up a front-end proxy Apache httpd, which should forward the requests to individual Tomcats in function of the URI prefix, and strip this prefix while doing so. Preferably, you would like to do the proxying via mod_jk. That is a problem, because the standard proxying instructions of mod_jk (JkMount e.g.), do not provide a syntax for forwarding URI's, and modifying these URIs at the same time. That is why Mark originally oriented you to mod_proxy and mod_proxy_ajp, which can do that, for example as : ProxyPass /tomcat7 ajp://tomcat7-host:8017 ProxyPass /tomcat6 ajp://tomcat6-host:8016 ProxyPass /tomcat5 ajp://tomcat7-host:8015 (and have each Tomcat listen on the apropriate port with its AJP Connector) Using the above, a request with URI http://myhost/tomcat7/webapp1; will be forwarded to the tomcat7 server with a URI of /webapp1, while a request with URI http://myhost/tomcat5/webapp1; will be forwarded to the tomcat5 server with a URI (also) of /webapp1. As far as I understand, this is what you want to achieve (although it is not via mod_jk, but via mod_proxy_ajp instead). Mark however pointed out the drawbacks of modifying the URI : when one of these applications generates a self-referencing URI, it will not by default re-insert the stripped host prefix. For example, if application /webapp1 on tomcat7 creates a page with a link to itself like href=/webapp1/something, it will not magically know to make this into href=/tomcat7/webapp1/something. And when this link is clicked in the browser, it will generate a request to http://myhost/webapp1/something;, and the above Proxy instructions in the front-end won't know what to do with it and will ignore it. And the same happens with redirects etc.. You can overcome this, but it is likely in the end to create more hassle than you really want. On the other hand, if you do /not/ modify the URI while proxying the call, then you end up with a much less easy configuration on the side of the Tomcats, as you have seen before. So maybe let's look at another kind of solution, involving DNS and VirtualHosts. Would a solution whereby you access the different Tomcats as follows be acceptable ? - http://myhost-tomcat7.company.com/webapp1 is forwarded to tomcat7's webapp1 - http://myhost-tomcat6.company.com/webapp1 is forwarded to tomcat6's webapp1 - http://myhost-tomcat5.company.com/webapp1 is forwarded to tomcat5's webapp1 If yes, then do as outlined below. For a start, I suppose that you want to have an Apache httpd front-end, and that the Apache httpd and all tomcats, all run on the same physical host. Step 1 : Suppose that the front-end Apache httpd host is currently known via DNS as myhost.company.com. Define 3 additional DNS aliases for it : - myhost-tomcat7.company.com - myhost-tomcat6.company.com - myhost-tomcat5.company.com Step 2 : define 3 new VirtualHost's in the Apache httpd front-end, one each with - ServerName myhost-tomcat7.company.com - ServerName myhost-tomcat6.company.com - ServerName myhost-tomcat5.company.com (I assume that you know how to do that) Step 3 : In each of these VirtualHost configurations, add the following lines : - in the myhost-tomcat7.company.com host, add ProxyPass / ajp://myhost-tomcat7.company.com:8017 ProxyPassReverse / ajp://myhost-tomcat7.company.com:8017 (and similarly for the other VirtualHost's) Step 4 : make each of your Tomcats listen on the corresponding AJP port : - tomcat7 listens on port 8017 - tomcat6 listens on port 8016 - tomcat5 listens on port

Re: JAR locked in Tomcat after using addUrl to dynamically add JAR to running webapp
On 20/10/2011 18:18, Bob DeRemer wrote:
Hi Tomcat Community:
BACKGROUND:
I have a Servlet-based WEBAPP that is running in Tomcat7, JDK 1.6.0_27 on
Windows Server 2008 R2 64-bit - all 64-bit. We make use of class.newInstance
quite a bit as we have a fairly modular, interface-based system, and create
class instances on the fly. As part of our extensibility, I'm also using a
pretty well documented hack [The code is listed below] for dynamically
adding JAR(s) so they are accessible immediately without stopping our WEBAPP
or the actual Tomcat server process. This process has worked great for both
JAR(s) in the WEB-INF/lib and for ones we dynamically added - until you try
and stop the WEBAPP via the Tomcat manager app.
PROBLEM:
This solution for dynamically loading JARs worked great as long as we
start/stop the actual Tomcat server process, but I found out the JAR(s) that
I have been dynamically loading this way are not released when you stop the
WEBAPP. I am using SysInternals Process Explorer to monitor the open file
handles of the Tomcat7 process. I can see that when I stop the WEBAPP, the
dynamically loaded JAR is still referenced.
QUESTION:
I made an assumption that calling
Thread.currentThread().getContextClassLoader() would provide me the
classloader of my WEBAPP - which should be the same classloader that all the
JARs in the WEB-INF/lib are in. We control the WEBAPP, so I assumed this was
a safe assumption.
The usage of the dynamically loaded JAR(s) is no different than the default
JAR(s) in WEB-INF/lib. None of the WEB-INF/lib JARs are left open when we
stop the WEBAPP - only the JAR(s) that are loaded via the addUrl approach
below.
I have been through a number of online articles when I first created this
logic - including a PDF by Ted Neward [while at Developmentor] that described
these approaches, but am not sure how to troubleshoot this further now.
If anyone has an answer or any suggestions, I would greatly appreciate it.
Do you have 'antiJarLocking' enabled on the Context?

Re: Tomcat 7 won't run as Windows service

Normally I do keep multiple instances, each installed as a service (on different ports with different service names), but they've always been of the exact same version. It was not clear to me whether you were adding a service or replacing it. Would there be an issue with different Tomcat versions installed at once? There shouldn't be. On my development box I did get the Tomcat Windows service to run after moving back to Java 6. But my last attempt to install and run a Windows service on our staging machine is now failing to run as a service as well, although I'm not getting the commons-daemon error like before. Again I can run it fine from startup.bat, and can install the service, but starting the service fails. Nothing notable in stdout or stderr logs, either. Event viewer says The david2 Tomcat 7 service terminated with service-specific error 0 (0x0). Bah. What exactly is needed for the Tomcat bootstrapping to find the Java install that it's to use? The service wrappers, e.g tomcat7w.exe, have a control panel with various tabs properties therein. You must either run that program with a parameter so it knows which service to refer to, or make a copy with the same name as the service, e.g. david7w.exe and then run it. I thought that setting JAVA_HOME in setenv.bat was a way, but apparently that's not used when it runs as a service. See above, and: http://tomcat.apache.org/tomcat-7.0-doc/windows-service-howto.html Use the popup to select the Java version you wish to run. p Is it a matter of having JAVA_HOME set at the time that the service is created, and it keeps that value in the service configuration somehow? Or does the JAVA_HOME env var have to be set in the environment of the service that's trying to run, every time it starts?

Re: How to externalize a webapp's logging.properties?
On 11/10/2011 07:28, Dan Checkoway wrote:
Hello,
I run several webapps under one instance of tomcat (7.0.21 currently, fwiw),
and each webapp uses JDK logging and needs to log to its own separate log
file. I accomplish this by placing logging.properties in WEB-INF/classes,
and an example of how it's set up is:
handlers = org.apache.juli.FileHandler
org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = ${catalina.base}/logs
org.apache.juli.FileHandler.prefix = my-webapp.
org.apache.juli.FileHandler.formatter =
com.mycompany.logging.MyCustomFormatter
...all of my logging levels...
You can configure the main logging.properties to output separate files
per application, as per:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
The Manager application is configured like this.
p
(and fwiw, my custom logging formatter lives in a jar that I place in
$TOMCAT_HOME/endorsed)
It works great. The challenge I face, however, is that I deploy my webapps
as .war files, and I'd like to be able to deploy the same exact .war file to
different environments...dev, test, staging, production. And I'd like to be
able to use different logging level config in each of those environments.
As it stands right now, I'm sorta confined to that single instance of
logging.properties that gets built into my webapp. I want to
externalize this moving part if possible.
I played around with omitting logging.properties from my webapp, and instead
using just $TOMCAT_HOME/conf/logging.properties, but (a) I wasn't able to
get it to work the same as it's working right now, and (b) that funnels me
into sharing logging level config across my webapps (in other words,
webapp 1 can't have a different logging level for package x.y.z than webapp
2). Forget (b) for the time being, since I can live with shared logging
levels across webapps. The main issue I'm having with this approach is that
I can't seem to get *all* of my logging to go to my webapp-specific log
file. Some stuff still gets logged to catalina.out.
So...
1. Is it currently possible to do what I'm trying to do? Per-webapp logging
control without using WEB-INF/classes/logging.properties? I could really
use a working example if this is doable.
2. Is there any other hook I can take advantage of (i.e. a context listener
or something), by which my code can get invoked prior to JULI initializing
for my webapp, where I might be able to override the
java.util.logging.config.file system property, or something like that?
3. If neither of those options is possible, how feasible would it be to add
a feature to tomcat, where you can configure a path to logging.properties
(in theory classpath: or file: style) on a per-webapp basis? i.e. in
conf/server.xml in the Context.
Or if there's an easier way, shove me toward it...
Thanks,
Dan

We use a single tomcat instance (soon switching from 5.5.23 to 7.x) with 24 webapps. Each webapp is based on spring and hibernate doing a lot of I/O during initialization. Tomcat is often restarted which causes long downtimes. As far as i can see the tomcat initializes its wepapps sequentially. So despite the fact, that our tomcat-intance runs on a 8 core linux system, tomcat seems to use a single thread to initalize the webapps. Is there a way on tomcat 7 to make it initialize webapps in parallel? Nope. Or is there a basic obstacle? Not that I can think of off the top of my head. Just that no-one has felt the need to scratch that particular itch. Both start and stop needs to be taken care of. If you want to propose a patch, this might provide a starting point: https://issues.apache.org/bugzilla/show_bug.cgi?id=46264 I've added some review comments to that patch that you may want to consider when writing a patch. If you need any help with the patch, just ask here. Thinking about this has got me interested. If you decide not to take a look at writing a patch for this, I'll probably take a look - maybe later this week.

Re: Loading Super Classes with ClassLoader in Tomcat
On 11/10/2011 12:59, Peter Lavin wrote:
Hi Christopher, Pid, Filippo, thanks for your help. I have got this
working as required on my Tomcat server. Here is the code that works.
public class MyCustomClassLoader extends ClassLoader {
public MyCustomClassLoader(ClassLoader contextClassLoader) {
super(contextClassLoader);
}
public synchronized Class? arrayToClass(String name, byte[] ct,
boolean resolve) {
Class? c = defineClass(name, ct, 0, ct.length);
try {
this.loadClass(c.getName());
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
if (resolve)
System.out.println(Resolving Class in + this.getClass());
resolveClass(c);
return c;
}
} // end class
// This is called by...
MyCustomClassLoader cl = new
MyCustomClassLoader(Thread.currentThread().getContextClassLoader());
Class? sp = cl.arrayToClass(null, byArray, True);
// use the now loaded class sp for something here
So passing the parent ClassLoader to the constructor was the key.
I'm curious to know what the class
org.apache.catalina.loader.WebappClassLoader is intended for?
I was trying to do...
MyCustomClassLoader extends org.apache.catalina.loader.WebappClassLoader{
It's the classloader the webapp uses. Extending it doesn't mean you
inherit the relationships it holds, you still have to pass in a parent
classloader in the constructor.
p
and had to add tomcat-catalina-7.0.0.jar to my dependencies in Eclipse.
This works in the IDE but I get the following error when attempting to
deploy the subsequent war in Tomcat (as the jar ended up in the WAR file
too)...
Oct 11, 2011 10:42:30 AM org.apache.tomcat.util.digester.Digester
endElement
SEVERE: End event threw exception
java.lang.NoSuchMethodException: org.apache.catalina.deploy.WebXml
addServlet
What is the class WebappClassLoader intended for? It looks like what
Christopher's question is valid :-)
I have a question, though, since the default parent ClassLoader of
any ClassLoader /should/ be the current thread's context ClassLoader,
so none of the above code should be necessary.
but the default ClassLoader used does not appear to be the one of the
Webapp in question.
thanks again,
regards,
Peter

Hi Filippo, tks for your reply.
I'm not actually specifying any ClassLoader, perhaps I should? How
should I specify a ClassLoader to use when dynamically loading a class?
You can pass one into the Constructor of your own classloader:
public CustomClassloader(ClassLoader parent) { super(parent); }
And to be perfectly explicit, OP should be doing this when
constructing their CustomClassLoader (presumably in a
ServletContextListener):
CustomClassLoader cl = new
CustomClassLoader(Thread.currentThread().getContextClassLoader());
This should allow Peter's ClassLoader to find superclass definitions
from the webapp's ClassLoader.

Perhaps the CustomClassLoader is being initialized in a weird way
that does not make the above connection.
