How can I limit the number of instance my servlet can server concurrently?
Is it possible to limit Tomcat to just handle 10 concurrently request to my servlet? for all others (11 and onward), it will queue them up, and serve them only when one of the currently-serving request is done?

tomcat one more then one CPU
Hello, Can we configure tomcat in a way that it uses more then one CPU? It seems to use only one CPU ? We are using the following: - Sun Fire v240 (with 2 CPU's) - Solaris 8 (including patches) - tomcat 5.5.7 - Java 1.5.0 Thanks Walter

Re: how to control lifetime of JSessionID cookie in Tomcat 5.5
I think you mixing things up. The http session isn't designed to run forever. The session ends as soon as the user closes his browser. If you want to have some kind of direct login, you should just set your own cookie, evaluate this cookie in your first servlet/jsp/action or filter and login the user properly. Trying to prolong the session duration is surely not the right way to do it. regards Leon On 4/4/06, Andrew E.

Why?
Any idea will be appreciated!
This error implies there is something wrong with your configuration, and
that the registration of the resource did not get completed successfully.
In my experience, there's usually a stack trace in the Tomcat logs that says
why it didn't get processed. You might also want to add a call to:
e.printStackTrace();
inside your exception handler to see where the error is actually coming
from.
I don't use Tomcat 5.5 much myself (primarily 5.0) so I can't help you much
more than that ... best bet would be to ask questions on the Tomcat user
mailing list.

In your particular case, the most likely problem is trying to use the

removed in Struts 1.2. You should use the JNDI data sources provided by
your container (Tomcat) instead. There is pretty reasonable
documentation
on the Tomcat web site for how to set this stuff up, which applies to
all
webapps, not just Struts based ones.
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
Historical note -- the only reason Struts 1.0 supplied a data source
implementation in the first place was that, six years ago, most servlet
containers did not support JNDI based resource access. Now that they
(essentially) all do support JNDI, that is the recommended mechanism for
managing data sources.

cluster prblem
hi, I created a tomcat cluster (using tomcat 5.5.15 and jdk 1.5.0_06 in linux) with two nodes, by uncommenting the existing cluster element in server.xml and changing the tcplisten ports. And I created a web application to test the cluster (put and entry distributable/ in web.xml). Then I deployed the application in both servers and started the servers. When I see the logs there are no errros and every things seems to be ok. Then I access the application of one server, and see the nummber of sessions of that application in both servers using tomcat manager. Here I found that both nodes have sessions and according to my application i think that session is being replicated. But when i check the catalina.out it has following exception. SEVERE: TCP Worker thread in cluster caught 'java.io.IOException: Connection reset by peer' closing channel java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:21) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233) at sun.nio.ch.IOUtil.read(IOUtil.java:206) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:207) at org.apache.catalina.cluster.tcp.TcpReplicationThread.drainChannel (TcpReplicationThread.java:125) at org.apache.catalina.cluster.tcp.TcpReplicationThread.run( TcpReplicationThread.java:69) And also In my web application I have a class which implements the HttpSessionActivationListener, HttpSessionBindingListener and Serializable interfaces. and I store an instance of this class as an attribute of the httpSession. In this case I think the sessionWillPassivate and sessionDidActivate should be called when the session is replicated across different jvms. But it seems this does not happens. (i.e. it does not print my log messages) can someone explain this, amila.
Re: PHP Servlet Fails in Tomcat 5.5.15-SOLVED
Hi all. Just one opinion, if it hasn't been said before. Do not mix Java and PHP. PHP is inherently thread un-safe. Basically the PHP code itself is, AFAIK, OK (thread safe), but all those myriads of 3rd-party libraries providing needed functionality to the myriads of PHP extensions can, and some are thread un-safe. In case you haven't noticed, most decent Linux distros disable multi-threaded MPMs in Apache, if you enable PHP in them. Well, if Apache feels unsafe with PHP around, how should you feel in Tomcat? I can understand why you would want to run PHP, a lot of freeware projects out there were written in PHP. Or, should I be more precise, in PHP+MySQL glued together. Perhaps you cannot afford to rewrite it all. But sometimes, it is worth it. Decision remains yours, but I would run PHP separately from TC, if at all possible. Nix. __ Do You Yahoo!? Tired of spam?

jdk1.5, tomcat 5.5.9 and jsp compilation
I've a problem compiling jsp's against jdk1.5. I've searched the archives, google, tomcat docs etc but found no help on my specific issue although I can see anumber of people have had problems with generics support. I've changed to the Ant compiler and copied the ant.jar to common/lib, added the compiler parameters to conf/web.xml to enable 1.5 compilation. I still get a message saying that generics are not supported and I should change the -source 1.4 to -source 1.5. I've looked through the ant docs and this appears to be related to the javac tag in build.xml, but I'm not sure where to put this tag in the context of a tomcat installation. I've looked through the tomcat docs on jasper (how-to) but I believe I've removed the dependency on japser so I dont think this is relevant, although it does mention using the 'javac' argument with catalina.sh. I've tried this with no success, but it's quite possible I didn't configure this properly as I'm not sure where catalina.sh is called from. I've looked through the .sh files but it's not clear. To sum up, I would like to know how to configure '-source 1.4' to '-source 1.5' or am I barking up the wrong tree? thanks *** The Royal Bank of Scotland plc. Registered in Scotland No 90312.

Once the needed adress translation tables do not fit into the TLB, performance gets bad. Since Java often uses a large and continuous heap it's a very good candidate for using large pages, saving entries in the Hmmm, Im not sure about this. I do agree that a page size too small will make a heavy use of CPU/OS internal structures, resulting in poor performance. OTOH, using a page size too big results in degradation of effectiveness of that processes working set. Suppose a whole block of 1 MB was out of the TLB or swapped out. Operating on a relatively small, well grouped memory region, would result in the whole 1 or 2 MB of memory be introduced into the active set, instead of just those smaller pages. Of course, having portions of your memory collect dust, could be a sign of poor programming, memory leaks and what not. You mileage may vary. Setting a page size to 2 MB may be a bit extreme. If it can be set to just one process and dynamically, or at least at startup, that would be coll. Somehow, I doubt this level of flexibility exists.

GET FORM Encoding Test JSP
Hi,
The following JSP presents a well-known problem found all over the web
regarding GET form submissions not encoding form parameters properly. The issue
does not exist with POST.
I have read just about every article on the web about this issue, and the below
JSP incorporates all of the solutions.
However, it still does not work and I wonder having seen a few suggestions that
this could be the fault of Tomcat, whether there is any truth in this, since an
equivalent ASP test does not exhibit the issue.
I have used the below JSP test with both a SetCharacterEncodingFilter in front,
and without (this is also catered for by the request.setCharacterEncoding
call).
Everything reads UTF-8 except when you submit the word Amélie into the form,
the output is broken. Interestingly, the QENC string which converts the
request.getParameter to UTF-8 fixes the string. This is impracticle I would
have thought and should be converted by Tomcat given the request encoding which
is correctly set.
My question - is this a Tomcat bug, a Tomcat caveat, or my own silly fault?
Thanks, Allistair

SEVERE: TCP Worker thread in cluster caught 'java.io.IOException: Connection reset by peer' closing channel java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:21) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233) at sun.nio.ch.IOUtil.read(IOUtil.java:206) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:207) at org.apache.catalina.cluster.tcp.TcpReplicationThread.drainChannel (TcpReplicationThread.java:125) at org.apache.catalina.cluster.tcp.TcpReplicationThread.run( TcpReplicationThread.java:69) And also In my web application I have a class which implements the HttpSessionActivationListener, HttpSessionBindingListener and Serializable interfaces. and I store an instance of this class as an attribute of the httpSession. In this case I think the sessionWillPassivate and sessionDidActivate should be called when the session is replicated across different jvms. But it seems this does not happens. (i.e. it does not print my log messages) can someone explain this, amila. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: cluster prblem
ok thankx for reply, What a about not calling methods of HttpSessionActivationListener listner. I set an object (of which class implements the HttpSessionActivationListener) as an attribute of the session. i think when this session being migrated conatiner should call these methods amila.

RE: Tomcat tag question
Here is a quick smattering to do what you want; this is the dofilter for
the cclass you'll write that extends filter. You'll want to append
stuff at the end... play with it a little and you'll get the idea pretty
quick.You can alter anything in the body.. but for your case, just
add your meta tag to the end.
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse)
response;
CharResponseWrapper wrapper = new

Sorry to bother you with what is most likely a silly question, but i
have been googling, and found no real answers and was hoping you might
know. I am doing another Tomcat project and to that end, i need to get
tomcat to behave in a certain way, namely i need tomcat to add an html
tag to each page requested, like so:
meta name=agmips value=1.963752
where the value is a box identified (bad# good# bad# good# bad# good#)
-
672 in this case, actually i would LOVE to be the hostname of the box,
but can be anything really - even static if it cant be done
dynamically.
Is this possible? And if so, would you mind sharing the trick with
this
newbie?
Hmm... Isn't this a job for JSP. Rename your index.html to index.jsp
and add a new first line of:
%@ page language=java %
Then insert this into the point you want the page output to change:
meta name=agmipsvalue=%=request.getServerName()%
Best of luck,

[OT] AIX filtering Explorer?
Hi everybody, I marked this message as OT because it may not pertain to Tomcat, even if I presume so. I have a problem with a Jboss/Tomcat 5.5 installed on an IBM AIX machine. The application redirects user requests to an encrypted channel at login: 1) The browser sends an unsecure request. 2) the request is redirected to a secure channel I have no problem with Firefox, while IE looks as if it get lost. The secure request does not arrive on the tomcat server. Where did it go? I've put a proxy in the middle so I'm pretty sure the connect request is made on the correct URL.

The problem is that AJP/1.3 only allows a maximum of 8Kb to be sent in a given packet. For the Request packet this has to include all of the Request headers, as well as the SSL variables. I'm guessing (since you say you are doing a POST), that the referer URL is very long, and that FireFox is adding just a bit more than MSIE to push it over the edge. If it's possible for you to hack your copy of the mod_jk code, then putting something like: jk_dump_buff(l, __FILE__, __LINE__, ajp_marshal_into_msgb, JK_LOG_LEVEL_TRACE, ssl_cert, msg); at line 490 of jk_ajp_common.c, and configuring your log-level to trace will give you the info to see what is wrong. And feel free to post the results to the list: Myself and at least a couple of other people can parse what the data in an AJP/1.3 message is. Thanks for your help. It turns out that the referer for this page is indeed HUGE! I turned off referer sending in Firefox and this fixed it. I will talk to my vendor about using POST instead of GET.

Tomcat Clusters, private network for replication, and Oracle 8i JDBC driver
I have a 3-node cluster, running on Linux. All 3 boxes are identical. Eth0 - A class B network address - The 'public' interface for web traffic (public in that it goes back out through httpd to the internet) Eth1 - A class C network address - The 'private' interface for replication. I.e. Receiver className=org.apache.catalina.cluster.tcp.ReplicationListener tcpListenAddress=192.168.x.y tcpListenPort=4009 tcpSelectorTimeout=100 tcpThreadCount=6/ Tomcat clustering all works fine. The problem comes when I request a connection from the connection pool to an Oracle 8i data source, like the following: Resource name=jdbc/dbname type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver url=jdbc:oracle:thin:@hostname.company.com:1521:dbname username=user password=password validationQuery=SELECT COUNT(*) FROM DUAL initialSize=10 defaultCatalog=dbname maxIdle=20 maxWait=5000 maxActive=50/ If I have the private network enabled for replication, then the Oracle thin driver insists on trying to connect through this interface first. This happens on a class A network (10.0.x.y) as well as a class C network (192.168.10.y). It also happens if the OS happens to be W2K. It will take 5 seconds and time out, and the connect through the class B address. With 10 data sources (on Oracle) I get a connection pool startup time of 50+ seconds (minimum). If I turn off the class C (or class A) private network and replicate on my class B network, this problem does not happen. Can anybody explain to me why this is the case? Has anyone else seen this? Has anyone else got this working as expected? Should I even bother trying to keep the replication traffic on a private network? The boxes have 4 gig connections and so it seems like I should be able to make use of the other 3. Thanks, Tim P.s. Yes I know Oracle 8i pre-dates modern man and is no longer supported.

Connecting Apache 2.2 and Tomcat 5.5.16
Hi there =) I've been trying to figure out how to get my Tomcat 5.5.16 to play with an Apache 2.2. (and Linux) I'm new to configuring these applications and seem to get lost in the documentation. mod_jk, mod_jk2 (same as jk2?), mod_proxy, mod_proxy_balancer, mod_proxy_ajp APR, AJP etc. and my head starts spinning.. :o\ Well basically what I though was to set up an Apache server and more then one Tomcat servers with some load balancing. Am I wrong if I have the impression that Apache is the way to go with 128bit SSL and as the front end for load balancing? Everything else should be handled by Tomcat, even static content I think. (Thinking of some hardware SSL offloader if Apache don't handle it all that well. Too bad they are not free too ;) First of all giving my wishes, what connection type should I use? Then how to write the proper configuration settings for my Tomcat and Apache versions? And last, how much load can an Apache server and Tomcat server expect to handle of request/sec?

PostgreSQL access via JNDI
I've been trying to get PostgreSQL set up to be accessed through JNDI in Tomcat 5.5.x. I found the docs page describing it, jndi- datasource-examples-howto.html, and followed the example there, but it still doesn't work. I'm trying to provide access to PostgreSQL for use by both JDO and JCR in my web-apps. Here's the Resource definition I'm using: Resource name=jdbc/whisper_db auth=Container type=javax.sql.Datasource driverClassName=org.postgresql.Driver url=jdbc:postgresql://127.0.0.1:5432/my_db username=--- password=--- maxActive=10 maxIdle=100 maxWait=3000 / In my application's META-INF/context.xml, I have the following ResourceLink: ResourceLink global=jdbc/whisper_db name=jdbc/whisper_orm type=javax.sql.Datasource / In my application's WEB-INF/web.xml, I have the following resource- env-ref: resource-env-ref descriptionWhisper's Database/description resource-env-ref-namejdbc/whisper_orm/resource-env-ref-name resource-env-ref-typejavax.sql.Datasource/resource-env- ref-type /resource-env-ref Depending on where I put the Resource definition, I get different errors. If I put it in the web-app's META-INF/context.xml, or in $TOMCAT_HOME/ conf/context.xml, my JDO implementation complains: NestableRuntimeException: There was an error duing JNDI lookup of the name java:comp/env/jdbc/whisper_orm.

Is there any logging that I can turn on that will tell me the WHY Tomcat Cannot create resource instance? Or am I doing something obviously stupid with my Resource definition? Or could it be something else entirely? Any suggestions would be really helpful. Thanks! Mark - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Connecting Apache 2.2 and Tomcat 5.5.16
mod_jk, mod_jk2 (same as jk2?), mod_proxy, mod_proxy_balancer, mod_proxy_ajp APR, AJP etc. and my head starts spinning.. :o\ From what I understand, as of Apache 2.2, the mod_jk project no longer applies. Instead, the mod_proxy module is a generic way to proxy from Apache HTTPD to other servers. So for Tomcat, the mod_proxy_ajp module will proxy from Apache HTTPD directly to Tomcat using the AJP protocol. This is much simpler than ever, here is how I do it for one of my servers... VirtualHost 12.34.56.78:80 ServerName my.server.com ProxyPreserveHost On ProxyPass / ajp://12.34.56.78:8009/ /VirtualHost ...which passes all requests for my.server.com to Tomcat, with an AJP connector listening on port 8009... Connector address=12.34.56.78 port=8009 protocol=AJP/1.3 enableLookups=false minSpareThreads=20 maxSpareThreads=100 maxThreads=200 connectionTimeout=6 / ...it's very simple now, no workers.properties or crazy mod_jk directives. In fact mod_proxy_ajp is included with Apache 2.2. Well basically what I though was to set up an Apache server and more then one Tomcat servers with some load balancing. Am I wrong if I have the impression that Apache is the way to go with 128bit SSL and as the front end for load balancing? I have it set for SSL, which still uses the exact same proxy diretives, since the proxying is done using AJP after Apache does all the SSL protocol stuff. Again, very simple. As for load balancing, I believe this would be handed by some additional mod_proxy directives. Bernie - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Filter Help!
Hello everyone,
If this is not the right place to post this could you please let me know
where. I have searched the forums and Google and cannot find an answer.
I have a Servlet filter that checks to see the content length of the
request.
long contentLength = request.getContentLength();
If contentLength is greater than some configurable size, I would like to
stop the request and send back a response saying that the request is to
large.
This is being used for a file upload Everything is working, except it
seems like the ENTIRE request (or file) is sent BEFORE my redirect is
happening.
My logs are showing the correct information at the appropriate times,
but the entire request is being processed before I can send a request
back.
Is there a way to immediately cut off the request and return a
response? Is there a better way to do this?
Request Size Filter: REQUEST LENGTH=401458785
Request Size Filter: CONTENT TYPE=multipart/form-data;

javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
Why?
Any idea will be appreciated!
This error implies there is something wrong with your configuration, and
that the registration of the resource did not get completed successfully.
In my experience, there's usually a stack trace in the Tomcat logs that says
why it didn't get processed. You might also want to add a call to:
e.printStackTrace();
inside your exception handler to see where the error is actually coming
from.
I don't use Tomcat 5.5 much myself (primarily 5.0) so I can't help you much
more than that ... best bet would be to ask questions on the Tomcat user
mailing list.

In your particular case, the most likely problem is trying to use the
Struts
data source. This functionality was deprecated in Struts 1.1, and was
removed in Struts 1.2. You should use the JNDI data sources provided by
your container (Tomcat) instead. There is pretty reasonable
documentation
on the Tomcat web site for how to set this stuff up, which applies to
all
webapps, not just Struts based ones.
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
Historical note -- the only reason Struts 1.0 supplied a data source
implementation in the first place was that, six years ago, most servlet
containers did not support JNDI based resource access. Now that they
(essentially) all do support JNDI, that is the recommended mechanism for
managing data sources.

SV: Connecting Apache 2.2 and Tomcat 5.5.16
Thanks! This sounds promising :D I guess I need to figure out what modules I need to load etc. It seems like my Apache installation don't have any mod_proxy_ajp.so (or what the name is). I think I'll need to fiddle with my server and see what else is running. For my contect I have a feeling I would need these modules; - mod_proxy - mod_proxy_ajp - mod_proxy_balancer - mod_ssl Anything else I need to set up? (And if so, why?) My plan was to remove as much modules etc. as possible. -Erik -Opprinnelig melding- Fra: Bernie Durfee [mailto:[EMAIL PROTECTED] Sendt: 4. april 2006 21:10 Til: Tomcat Users List Emne: Re: Connecting Apache 2.2 and Tomcat 5.5.16 mod_jk, mod_jk2 (same as jk2?), mod_proxy, mod_proxy_balancer, mod_proxy_ajp APR, AJP etc. and my head starts spinning.. :o\ From what I understand, as of Apache 2.2, the mod_jk project no longer applies. Instead, the mod_proxy module is a generic way to proxy from Apache HTTPD to other servers. So for Tomcat, the mod_proxy_ajp module will proxy from Apache HTTPD directly to Tomcat using the AJP protocol. This is much simpler than ever, here is how I do it for one of my servers... VirtualHost 12.34.56.78:80 ServerName my.server.com ProxyPreserveHost On ProxyPass / ajp://12.34.56.78:8009/ /VirtualHost ...which passes all requests for my.server.com to Tomcat, with an AJP connector listening on port 8009...

In fact mod_proxy_ajp is included with Apache 2.2. Well basically what I though was to set up an Apache server and more then one Tomcat servers with some load balancing. Am I wrong if I have the impression that Apache is the way to go with 128bit SSL and as the front end for load balancing? I have it set for SSL, which still uses the exact same proxy diretives, since the proxying is done using AJP after Apache does all the SSL protocol stuff. Again, very simple. As for load balancing, I believe this would be handed by some additional mod_proxy directives. Bernie - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If-Range bug in DefaultServlet?
Hi
I've been making If-Range requests to Tomcat (5.5.16) and it seems
not to be sending back content when the request and current ETags
don't match.
RFC 2616 section 14.27 says
If the entity tag given in the If-Range header matches the current
entity tag for the entity, then the server SHOULD provide the
specified sub-range of the entity using a 206 (Partial content)
response. If the entity tag does not match, then the server SHOULD
return the entire entity using a 200 (OK) response.
Am I doing something wrong, or is the servlet behaviour not as it
SHOULD be?
Thanks in anticipation

Re: jdk1.5, tomcat 5.5.9 and jsp compilation
I can vague remember issues about tomcat 5.5.x which came out with the jdt from eclipse which had no support for 1.5. I maybe also be completely wrong here.

The Sun JVM should use as many CPUs as are available, but keep in mind that each thread the JVM spawns can only use one CPU at a time.

Re: Tomcat Clusters, private network for replication, and Oracle 8i JDBC driver
Just a thought, you are using IP addresses for replication. But hostname for Oracle, have you checked out local DNS issues with the jdbc:oracle:thin:@hostname.company.com:1521:dbname ? Check the IP address records are correctly setup, and everyone listed is connectable and working. Check all your local DNS caching servers are operational. However for DNS issues I would expect ping/ssh to be affected too. Can you configure an IP address in the JDBC connection string ? Do you have 2 default routes setup on your clustered boxes ? You do not say in your original mail which directly connected network eth0 is on, I now read it as 172.25.x.y from your follow up. What does your routing table look like. One reason why the oracle driver uses eth0 over eth1 is that when the JDBC client opens the socket to connect it is not bound to any specific interface. Where as with replication I'd guess the tcpListenAddress forces which physical card it will use. Normal then the socket is auto-bound (within the kernel) it will choose the default address of the physical interface closest to the host (or gateway - if nto directly connected). Have you setup any interface aliasing that might confuse the kernel. For example you have IP addresses in overlapping subnets on two physical interfaces in the same host ? When the JDBC client does get connected to the SQL server, what does 'netstat' show for the IP addresses of that connection ? Is it using the 172.25.x.y: -- 172.25.x.z :1521 as you expect ? -- Darryl L. Miles - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

virtual hosts on tomcat 5.0.28
I have been trying to create a virtual host with tomcat 5.0.28 to no
avail. I have read all the docs. read the Wiki. and still no joy.

I was hoping to leave up the manager and admin page and then have the
server respond to a dns name for my reall web app. Am I completely naive?
I tried the following:
http://wiki.apache.org/tomcat/CreateVirtualHosts?action=diff
Which is:
0. create ${catalina.home}/www/appBase , ${catalina.home}/www/deploy,
and ${catalina.home}/conf/Catalina/www.myhostname.com
1. add a host entry in the server.xml file
Host appBase=www/appBase name=www.myhostname.com/
2. Create the the following file under
conf/Catalina/www.myhostname.com/ROOT.xml
?xml version=1.0 encoding=UTF-8?
Context
path=/
docBase=www/deploy/mywebapp.war
reloadable=true antiJARLocking=true
/Context
Add any parameters specific to this hosts webapp to this context file
3. put your war file in ${catalina.home}/www/deploy

The site processes anywhere between 400,000 and 700,000 JSP pages per day. I've included the configuration files at the bottom of this message. Usually, the site runs great. No problems whatsoever (well, my code occasionally crashes, but that's to be expected). But once in awhile, my mod_jk seems to suddenly start to lose connections to my tomcats. mod_jk.log sees this: [Tue Apr 04 18:23:35 2006] [info] ajp_process_callback::jk_ajp_common.c (1384): Connection aborted or network problems [Tue Apr 04 18:23:35 2006] [info] ajp_service::jk_ajp_common.c (1731): Receiving from tomcat failed, because of client error without recovery in send loop 0 [Tue Apr 04 18:23:35 2006] [info] service::jk_lb_worker.c (711): unrecoverable error 400, request failed.

All new requests seem to get stuck in this state. Quickly, the apache fills up and new requests are locked out. If I look at my tomcat logs, I see that processing has slowed and stopped. One interesting thing is that if I kill and restart my apache, the tomcat logs go crazy with output, as if killing the apache somehow unsticks them. Is something running out of sockets? If I had to guess, I'd say that it feels like mod_jk can't receive the data back from the tomcats, but thats just a hunch. I've seen the apache mod_jk config page which seems to have a bunch of different parameters for dealing with stuck tomcats, but I'm unsure of which one to use, because I don't really know whats happening or what the problem is. I've found other posts on the web that list similar problems, but haven't seen any Oh this is the problem and this is the simple solution. I haven't yet dug in with netstat to see what's going on network-wise, I'm hoping there some magical bullet configuration parameter that will help. C'mn magic bullet!!

Re: about maxProcessors attribute
Since MaxClients is so big, I'm assuming that you have a pre-fork MPM Apache. In this case, you are strongly recommended to have maxProcessors = MaxClients, since each client will have it's own connection to a processor. If you include something like connectionTimeout=6, then the Tomcat processors will eventually die off if the Apache child doesn't get any requests for awhile. Mostly useful if you are running an older Linux kernal. I think that the /manager/status Servlet for 5.0.x includes this information. However, since it's at most the number of Apache children, you should be able to approximate it via: $ ps -ef | grep httpd | wc -l Iratxe Etxeberria Sainz-Ezquerra [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi!

Diagnosing DBCP JDBC connection leak using removeAbandoned parm
Bear with me, I'll try to make this short, but want to give enough info/background that it makes sense. Basically we are a bit confused by the output of the DBCP logAbandoned parameter. Any help is appreciated. Environment: We are using Tomcat 4.1.18 (for now), MySQL 4.0.18, Java 1.5.0_04-b05, all running under Linux kernel 2.4.22-1.2115.nptlsmp on a dual Xeon dedicated server. Anyway, we determined that we had a connection leak when our application froze today. We obtained a thread dump and it showed that everyone of the Tomcat threads that were running application code, were waiting to get a connection from the DBCP pool. Each process looked something like this in the thread dump: Thread-171 daemon prio=1 tid=0x8a88a528 nid=0x46e9 in Object.wait() [0x9559f000..0x955a0700] at java.lang.Object.wait(Native Method) - waiting on 0x4a08cb78 (a org.apache.commons.dbcp.AbandonedObjectPool) at java.lang.Object.wait(Object.java:474) at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(Unknown Source) - locked 0x4a08cb78 (a org.apache.commons.dbcp.AbandonedObjectPool) at org.apache.commons.dbcp.AbandonedObjectPool.borrowObject(AbandonedObjectPool .java:117) - locked 0x4a08cb78 (a org.apache.commons.dbcp.AbandonedObjectPool) at org.apache.commons.dbcp.PoolingDataSource.getConnection(PoolingDataSource.ja va:110) at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:3 12) at com.acme.Connector.CreateConnection(Connector.java:56) at com.acme.OpenMailData.insert(OpenMailData.java:282) at com.acme.trackopenmail.doPost(trackopenmail.java:127) at com.acme.trackopenmail.doGet(trackopenmail.java:65) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Application FilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterCh ain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.ja va:260) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.ja va:191) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2415) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180 ) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve. java:170) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:641) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:172 ) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:641) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java :174) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invok eNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.coyote.tomcat4.CoyoteAdapter.service(CoyoteAdapter.java:223) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:261) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:360) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:632) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:590) at org.apache.jk.common.SocketConnection.runIt(ChannelSocket.java:707) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.jav a:530) at java.lang.Thread.run(Thread.java:595) So, we decided to change our removeAbandonedTimeout to 60 (from the default of 300 seconds) and also to supply the parameter logAbandoned=true for DBCP. So far, this seems to have helped the situation, but we realize that the real problem is that connections are not being properly closed and this is only giving us a bit of breathing room. The good news is that we immediately started seeing

Moving from Tomcat 4.1 to Tomcat 5.5 - issues?
We are about to move an application from Tomcat 4.1 to Tomcat 5.5. We are already running Tomcat 4.1 under Sun java 1.5 on 32-bit Linux on dual Xeon processors with 4GB of memory. Can anyone else comment on what we should expect as far as changes in stability and performance? Also, I am wondering if anyone has had problems moving a non-WAR webapp from 4.1 to 5.5. The applications is a sort of Content Management System and is not deployed as a WAR file - changing it at this point is simply not practical because of all of the content files that are in the webapp directory. Instead the application is build, using ant of course, including pre-compiling the JSP's - the end result is a set of jar files. These are then copied into the test or production environment.

I've changed to the Ant compiler and copied the ant.jar to common/lib, added
the compiler parameters to conf/web.xml to enable 1.5 compilation.
I still get a message saying that generics are not supported and I should
change the -source 1.4 to -source 1.5.
I've looked through the ant docs and this appears to be related to the javac
tag in build.xml, but I'm not sure where to put this tag in the context of a
tomcat installation. I've looked through the tomcat docs on jasper (how-to)
but I believe I've removed the dependency on japser so I dont think this is
relevant, although it does mention using the 'javac' argument with
catalina.sh. I've tried this with no success, but it's quite possible I
didn't configure this properly as I'm not sure where catalina.sh is called
from. I've looked through the .sh files but it's not clear.
To sum up, I would like to know how to configure '-source 1.4' to '-source
1.5' or am I barking up the wrong tree?
