The current released version is Tomcat 6.0. Before that, there have been Tomcat 5.5 and Tomcat 5.0 and Tomcat 4.1, at least. If you want to get help for that or any other Tomcat-related subject, I would strongly recommend that you upgrade that Tomcat to a more recent version (and probably also the Java JVM). In case the above is not clear enough : it is not that nobody here /would want/ to help you; they would if they could. But Tomcat 3.3.2 is so old that some of the people here were probably still in school when it was released, and that any people here who have actually used it are probably over 50 years old.

java.util.logging - help needed with configuration and problem

I'm using JSVC to start Tomcat 6.0.20 as a daemon on Solaris. Java is
jdk1.6.0_16.
I need to deploy the same war file as 2 different contexts. Each context
has the same logging.properties file in the classes directory. The
conf/logging.properties has not been changed.
Problem: The logging from both contexts IBINET and IBMIN are being
written to both logs. ie IBINET.-mm-dd.log and IBMIN--mm-dd.log.
This did work on my PC where jsvc was not being used. Very difficult to
test with out jsvc on Solaris due to firewall.
Does the logging.properties file below look correct for loggers named
eocene.web.* ?

Re: Tomcat dies suddenly
Chuck, Thanks, I will give it a try after I complete the two experiments currently underway (the IBM JVM and running with strace from the command line.) Tried bringing the server running the IBM JVM into production this morning (tested it yesterday with different browsers... can't use IE 6 but all the others seemed to work) but couldn't as there is some problem with SSL. The indicators are that some people can access the application just fine but others (they appear to be mostly IE users, will be getting the IE versions later this morning) never get past the first page (I can see from the log what is requested)... the first page starts a series of processes including copying some signed jars down, if needed, starting an applet that serves as a conduit for moving information to printers, etc. The odd part is all of these worked fine yesterday when we were using the firewall to redirect traffic on a specific port to this server (yesterday, we were sending traffic on port 8084 to 443 on this server, this morning we were sending all 443 traffic to this server.) More testing this morning but all ideas are certainly welcome.

RE: Tomcat threads
scalable also seems to be a relative term here, and there are well documented strategies for scalability.

You should also read the servlet spec, in particular SRV.2.3.3.3: Implementations of the request and response objects are not guaranteed to be thread safe. This means that they should only be used within the scope of the request handling thread. References to the request and response objects should not be given to objects executing in other threads as the resulting behavior may be nondeterministic. If the thread created by the application uses the container-managed objects, such as the request or response object, those objects must be accessed only within the servlet's service life cycle and such thread itself should have a life cycle within the life cycle of the servlet's service method because accessing those objects after the service method ends may cause undeterministic problems. The illogical behavior you're asking for simply isn't allowed. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Problem setting keyAlias for https connector using tomcat 6.0 API's
Hello All, I m using tomcat connectorhttp://tomcat.apache.org/tomcat-6.0-doc/api/index.htmlAPI's to establish a connector (on some port both http https) at run time. I have no issues with the Http as of now. But Https, facing one issue. The connector specified on port is getting established successfully. I do it as following. connector.setPort(7005); connector.setProperty(keystoreFile, C:/myKeyStore.jks); connector.setProperty(keystorePass, keypassword); And some more properties. When there is more than one certificate in the keystore, I want it to pick particular certificate specified by alias. But when i set *connector.setProperty (keyAlias, mykey);* It’s not picking the certificate with specified alias, rather picking some random certificate. I tried with Connector port=7005 keystoreFile=pathToKeyStore keystorePass=keypassword keyAlias=mykey / This works very much fine. Can you please suggest me how to set keyAlias for connector using connector API's. Please let me know if more information is needed. Looking for your replies Thanks, Bhuvan

Why does the request have to be an HTTP request in order to have the

That does seem to be a bug.
Note that this is not actually a part of the AccessLogValve, it's just
part of Xie's implementation.
By default, the access logger logs the common
log web server
format, but of course it doesn't have to, so it should log non-HTTP requests
as well, but maybe
only if a non-default pattern is configured?
Fair enough: most of the information you'd want to log is from HTTP
requests (like the URI, for instance). The only things that are
available for non-HTTP requests are:
- - current date/time
- - transaction time
- - number of bytes read and sent
- - local address
- - remote address
- - request attributes
- - server name
Actually, that's quite a bit, but I've never seen an HTTP log that
doesn't log the URI :)
long t2 = System.currentTimeMillis();
long time = t2 - t1;
This isn't your choice, it's in the original code, but why not just do:
long elapsed = System.currentTimeMillis();
...
elapsed = System.currentTimeMillis() - elapsed;
??
Fewer items on the stack, etc.
Except that then it is more difficult to debug. Right? It isn't as easy to
inspect the value of
the current time if you perform the subtraction without first assigning the
current time to a
variable.
Fair enough, though debugging this timing code shouldn't really be required.
private Date getDate() {
// Only create a new Date once per second, max.
long systime = System.currentTimeMillis();
AccessDateStruct struct = currentDateStruct.get();
if ((systime - struct.currentDate.getTime()) 1000) {
struct.currentDate.setTime(systime);
struct.currentDateString = null;
}
return struct.currentDate;
}
I don't understand why this is ThreadLocal, instead of just synchronized
across the object. Maybe it's slightly faster to avoid the
synchronization and just use ThreadLocals, but I'm not sure how many
requests per second a single Thread is going to process, so I'm not
convinced that caching this data is worth the complexity it requires in
this class. I'd love to hear from a Tomcat dev about this.
Tomcat can (hopefully) answer a larger number of requests per second
every year on decently modern hardware. Benchmark it both ways on
a reasonably good/wide machine and you'll see why avoiding the sync
is helpful. I don't think it muddies the code very badly here.
Okay. Certainly avoiding object creation is a good idea, and avoiding
highly-contended synchronization is a good idea, too. I'd like to see a
performance comparison between these strategies, though. Maybe I'll run
one :)
The %b portion of the Combined Log Format is documented to be the size of
the object returned to the client, not including the response headers.
http://httpd.apache.org/docs/1.3/logs.html#common
Right. Presumably, the Content-Length is synonymous with the above, but
it might not be. Also, Content-Length is not always set, so you'll get a
lot of - written in the log even when response bodies actually has
content. In this implementation, %b is equivalent to %{Content-Length}o.
Counting bytes isn't that big of a deal, either. I'll submit a patch at
some point... maybe using a different pattern character.

It seems that you use Apache Httpd mod_proxy in front of your Tomcat, both located on the same server (this is the reason why get localhost).

Re: Access Log /Filter/?
Hello,
I think log.debug() method should first check current logging levels, or our
code will have those if() {} template everywhere.
I checked java.util.logging.Logger, and found this:
public void log(Level level, String msg, Object param1) {
if (level.intValue() levelValue || levelValue == offValue) {
return;
}
LogRecord lr = new LogRecord(level, msg);
Object params[] = { param1 };
lr.setParameters(params);
doLog(lr);
}
Java 6 hotspot can determine that the StringBuffer synchronization isn't
actually used across threads in many cases, and thus it doesn't bother
synchronizing. Thus, the performance of the two classes becomes identical.
http://www.javalobby.org/java/forums/t88518.html
But it is more secure to not depend on specific jvm version, so it is more

Fair enough: most of the information you'd want to log is from HTTP
requests (like the URI, for instance). The only things that are
available for non-HTTP requests are:
- - current date/time
- - transaction time
- - number of bytes read and sent
- - local address
- - remote address
- - request attributes
- - server name
Actually, that's quite a bit, but I've never seen an HTTP log that
doesn't log the URI :)
long t2 = System.currentTimeMillis();
long time = t2 - t1;
This isn't your choice, it's in the original code, but why not just do:
long elapsed = System.currentTimeMillis();
...
elapsed = System.currentTimeMillis() - elapsed;
??
Fewer items on the stack, etc.
Except that then it is more difficult to debug. Right? It isn't as easy
to
inspect the value of
the current time if you perform the subtraction without first assigning
the
current time to a

Fair enough, though debugging this timing code shouldn't really be
required.
private Date getDate() {
// Only create a new Date once per second, max.
long systime = System.currentTimeMillis();
AccessDateStruct struct = currentDateStruct.get();
if ((systime - struct.currentDate.getTime()) 1000) {
struct.currentDate.setTime(systime);
struct.currentDateString = null;
}
return struct.currentDate;
}
I don't understand why this is ThreadLocal, instead of just synchronized
across the object. Maybe it's slightly faster to avoid the
synchronization and just use ThreadLocals, but I'm not sure how many
requests per second a single Thread is going to process, so I'm not
convinced that caching this data is worth the complexity it requires in
this class. I'd love to hear from a Tomcat dev about this.
Tomcat can (hopefully) answer a larger number of requests per second
every year on decently modern hardware. Benchmark it both ways on
a reasonably good/wide machine and you'll see why avoiding the sync
is helpful. I don't think it muddies the code very badly here.
Okay. Certainly avoiding object creation is a good idea, and avoiding
highly-contended synchronization is a good idea, too. I'd like to see a

one :)

it might not be. Also, Content-Length is not always set, so you'll get a
lot of - written in the log even when response bodies actually has
content. In this implementation, %b is equivalent to

Re: Tomcat threads
Hi Charles, Let me explain the scenario. When tomcat gets a request, it does a socket send to some other process to handle the request and then respond. This would happen fast. But assuming 20k client requests come in at the same time, the server would try to allocate 20k threads and handle it. Mostly the system would trash and go down. But if it was to be handled gracefully, we can have the threads pick up the request throw it in a queue and let the worker threads work and respond. Let me know if I am missing something here.

I think log.debug() method should first check current logging levels, or

I checked java.util.logging.Logger, and found this:

if (level.intValue() levelValue || levelValue == offValue) {
return;
}
LogRecord lr = new LogRecord(level, msg);
Object params[] = { param1 };
lr.setParameters(params);
doLog(lr);
}
Java 6 hotspot can determine that the StringBuffer synchronization isn't
actually used across threads in many cases, and thus it doesn't bother
synchronizing. Thus, the performance of the two classes becomes identical.

But it is more secure to not depend on specific jvm version, so it is more
appropriate to use StringBuilder when necessary.

You should also read the servlet spec, in particular SRV.2.3.3.3: Implementations of the request and response objects are not guaranteed to be thread safe. This means that they should only be used within the scope of the request handling thread. References to the request and response objects should not be given to objects executing in other threads as the resulting behavior may be nondeterministic. If the thread created by the application uses the container-managed objects, such as the request or response object, those objects must be accessed only within the servlet's service life cycle and such thread itself should have a life cycle within the life cycle of the servlet's service method because accessing those objects after the service method ends may cause undeterministic problems. The illogical behavior you're asking for simply isn't allowed. At least not until Tomcat 7 ;). In there, you can do exactly what the user is asking for using the AsyncContext. The details are in the Servlet 3.0 spec, but basically the request is handed off to another thread and the original one returns to the pool. This also allows for two-way communication instead of relying on polling.

Tomcat doesn't do that - your webapp does. You have now introduced a previously unmentioned dependency - that the response depends on the behavior of an external resource, unrelated to Tomcat. That changes the picture considerably. The neat thing the servlet 3.0 AsyncContext does is handle this case by letting you decouple the original Request and Response objects from the original processing thread. But assuming 20k client requests come in at the same time, the server would try to allocate 20k threads and handle it. No, the server will allocate maxThreads request handlers; the other requests would sit in the TCP stack's queue (not in the JVM), up to the configured acceptCount value - which you can set as high as your OS allows. Mostly the system would trash and go down. Which is my point about why you don't want to set maxThreads to arbitrarily large (or small) values. But if it was to be handled gracefully, we can have the threads pick up the request throw it in a queue and let the worker threads work and respond. Which you can do in your webapp by sending an interim response to the client and having the client poll for the final one. You'd have to disable keep-alives as well. The 3.0 spec allows the container to perform this task, rather than requiring the webapp to do so. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

The most useful comment about StringBuilder in that thread was this: Re: StringBuffer Thus, the performance of the two classes becomes identical. Reality is more complicated than that. - You can't rely on latest/hardest optimizations in the HotSpot Client VM, which is the VM you gotta use for most desktop apps, games and others. - Optimizations are not portable. Just because Sun has optimizations X it doesn't mean that IBM, BEA, GCJ etc. (even at the same Java SE level) have it too, and vice-versa. - Optimizations are fragile and difficult to predict. Say you have a StringBuffer that is non-escaping (thus benefits from lock elision etc) because it's a local var of a single method. Now if this method grows too big and you refactor it into multiple smaller, private helper methods, suddenly the StringBuffer is passed from one method to another and it's not anymore a non-escaping local... unless, thanks to inlining or smarter escape analysis, the optimized code can handle it again as non-escaping... but now you're depending on a combination of several optimizations, and it's increasingly difficult (at least for the average developer) to predict the compiler's behavior and to rely on its behavior. Conclusion (for this particular optimization): Using StringBuilder is no more complex than StringBuffer, so there's no excuse to not use it when you now the buffer is unshared. Unlike some other optimizations, this doesn't confuse your code, doesn't create maintenance problems or incur increased development cost. in cases like this - where writing optimal code is just as easy as non-optimal code - I'd optimize since version 0. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

For log.debug() part, seems I misunderstood your meaning. Sorry about that,
you are right. But I do not think it matters too much. :)
Well, if were using tricks to avoid synchronization, we probably ought
to avoid four object creations (StringBuilder, char[] in sb, String, and
char[] in s) plus the character-copy operations. This is a filter that
is supposed to avoid performance impact on the webapp: this is such a
cheap optimization, it would be foolish not to do it.
Java 6 hotspot can determine that the StringBuffer synchronization isn't
actually used across threads in many cases, and thus it doesn't bother
synchronizing. Thus, the performance of the two classes becomes identical.
http://www.javalobby.org/java/forums/t88518.html
It's a rough reference from a comment on a blog. Gimmie something I can
really read, not I remember a guy saying once...
Jeremy Manson says this:
A final note. Some people think that there is no performance impact to
using StringBuffer instead of StringBuilder, because of all of the
clever things JVMs do to eliminate synchronization (I can blog about
this, too, if you want). This is a little unclear. Whether it can even
perform these optimizing transformations definitely depends wildly on
which JDK you use; I wrote a microbenchmark to test it, and the results
differed on different JDKs -- but all that microbenchmarks really
demonstrate is the performance of the microbenchmark.
(http://jeremymanson.blogspot.com/2008/08/dont-use-stringbuffer.html
from 24 August 2008)
But it is more secure to not depend on specific jvm version, so it is more
appropriate to use StringBuilder when necessary.
I agree. Using my own microbenchmark (below), these are the results I get:

It seems that, in these two environments, StringBuilder outperforms
StringBuffer by a small margin (5% on average in my Linux environment,
13% in my Microsoft Windows environment), but consistently.
It seems that the JVM has to do some work to even determine if the
synchronization can be eliminated before it can actually do it, so why
bother making it do that work in the first place? Avoiding
synchronization is simply the right choice.

The short answer is that if you haven't changed the conf/apps-admin.xml (yes, TC 3.3 was the first one to have context configuration files), then you need to edit the conf/users/admin-users.xml to enable a user for the admin app. The file posted by the OP is in the wrong format (it is for TC 4.0+). Of course, one of the things that the TC 3.3 admin app lacks is the ability to show the number of connections, so this will likely be of little use to the OP ;). It mostly lets you start and stop webapps. Since it shares connectors with later Tomcat versions, this information is available via JMX however. I told you, we need guys over 50 to answer questions about Tomcat 3.3.2. Maybe there's hope for us after all. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

No, the server will allocate maxThreads request handlers; the other requests would sit in the TCP stack's queue (not in the JVM), up to the configured acceptCount value - which you can set as high as your OS allows. I was assuming that the tomcat main thread is going to pick it up from the TCP stack and let the web server thread handle the request. Wont tomcat reject the request when max threads have been reached (since it would have already picked up tcp layer)? No, because the container doesn't know when a thread might become available. Serving content after a delay is considered better than not serving content at all, so the requests are simply queued in the TCP stack. - Peter
