Re: disable caching of static files in tomcat 5.5
- Original Message - From: Joerg Endrullis [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Tuesday, September 16, 2008 1:13 PM Subject: disable caching of static files in tomcat 5.5 Hi, I have a dynamically generated image a.jpg and I want Tomcat to always deliver the current version. Unfortunately Tomcat seems to have some kind of caching of static files? Where can one disable caching of static files in Tomcat? Why do I think Tomcat has caching of static files... You can reproduce the problem as follows: - create two different images x.jpg and y.jpg - then create a symbolic link from a.jpg to x.jpg, download a.jpg, change the symbolic link to y.jpg, download a.jpg again: $ ln -s x.jpg a.jpg; $ wget http://localhost:8180/a.jpg?time=0; $ rm a.jpg; $ ln -s y.jpg a.jpg; $ wget http://localhost:8180/a.jpg?time=1 You will see that both downloaded images a.jpg.1 and a.jpg.2 are equal to x.jpg, which leads to the conclusion that Tomcat uses some kind of caching. (in order to reproduce the problem, the commands have to be executed fast after each other, if you wait 5 seconds before the last wget, then Tomcat returns the correct image) Btw. it does not help to attach an artificial time-stamp to the URL: $ ln -s x.jpg a.jpg; $ wget http://localhost:8180/a.jpg?time=0; $ rm a.jpg; $ ln -s y.jpg a.jpg; $ wget http://localhost:8180/a.jpg?time=1 will produce identical images a.jpg?time=0 and a.jpg?time=1. Any help would be appreciated. Thanks, Joerg Joerg, not sure here... but this is what I think is happening... The images are been delivered to the page using ETAGS... basically they look at the file on disk size and modified time... If that changes they send it, if it does change it, nothing is sent to the browser... It seems to imply that symboloc links are not changing these links... but I dont think linux is that stupid... So I think its just the browser hanging on so try this... in the main JSP servlet/html page do this... response.setHeader(Cache-Control, no-cache); response.setHeader(Expires, Sun, 15 Jan 1998 17:00:00 GMT); response.setHeader(Pragma, no-cache); response.setDateHeader(Max-Age, 0); In html this is all meta tags... just look em up... Now you saying to the browser do not cache this page... and I'm hopng thats the images as well, and that ETAGS are not an issue with links... ie if it doesnt work... linux is showing tomcat the same modified time (doubtful) or tomcat can detect the change of the file, and does not update the etag stuff... more likely... hopefully telling the whole page not to cache gets around it... You have to do it all those ways because MS did their own thing... as usual ;) Have fun... --- HARBOR : http://www.kewlstuff.co.za/index.htm The most powerful application server on earth.

Dear all,
I seem to have problems with connection pooling.
I have tried so many ways, before I use to get the exhausted scenario,
where there were no connections left to use, and now I am getting a
different problem.
I have been digging in this issue for too long, and I am not sure if I
understand the depth of the connection pooling concept.
I have set the max active connections to 40.
My active connections keep increasing, they never seem to return back to
the pool,
eventhough when no-one is visiting the site.
(Well, I have had up to 3 idle connections and that is the most I have
ever had)
After a few days, the active connections reach to 37, and then
afterwards the active connections
are reset to 0.
It basically starts from 0 to 37 and then again 0 to 37, and so on
My understanding is that:
1. An active connection is a connection that is currently used, and not
yet returned back to the pool
2. An active connection will be returned back to the pool
straight after its usage and become an idle connection
The active connection is returned back to the pool as soon as you
call the connection.close() method (assuming that you have configured
for connection pooling)
3. An idle connection can only be idle for an X amount of time and then
it will be removed from the pool and get destroyed
4. An idle connection will become an active connection when it is
required and then returned back to the pool as an idle connection
when calling connection.close()
If that is all correct then why do my active connections keep
increasing?
Am I closing all the connections?
Well, I have checked every single line of code, and yes I am closing
result sets, statements and connections in a finally block:
[code]

results.close();
}

Yes, as I said in the first post, that I have checked through all the
code,
and I am closing all the connections (in a finally block) after they
have been used.
final Connection connection = datasource.getConnection();
try {
BUT you have a

It can never get to HERE
Just put the return after the finally

At the end of the servlet or JSP or whichever, you need to kill off
connections created that you establish.

Subject: Tomcat 5.5, JNDI Connection Pooling, Active connections keep

Dear all,
I seem to have problems with connection pooling.
I have tried so many ways, before I use to get the exhausted scenario,
where there were no connections left to use, and now I am getting a
different problem.
I have been digging in this issue for too long, and I am not sure if I
understand the depth of the connection pooling concept.
I have set the max active connections to 40.
My active connections keep increasing, they never seem to return back
to the pool, eventhough when no-one is visiting the site.
(Well, I have had up to 3 idle connections and that is the most I have
ever had)
After a few days, the active connections reach to 37, and then
afterwards the active connections are reset to 0.
It basically starts from 0 to 37 and then again 0 to 37, and so on
My understanding is that:
1. An active connection is a connection that is currently used, and
not yet returned back to the pool
2. An active connection will be returned back to the pool straight
after its usage and become an idle connection The active connection is
returned back to the pool as soon as you
call the connection.close() method (assuming that you have configured
for connection pooling)
3. An idle connection can only be idle for an X amount of time and
then it will be removed from the pool and get destroyed
4. An idle connection will become an active connection when it is
required and then returned back to the pool as an idle connection when
calling connection.close()
--
--
If that is all correct then why do my active connections keep
increasing?
--
--
Am I closing all the connections?
Well, I have checked every single line of code, and yes I am closing
result sets, statements and connections in a finally block:
[code]
} finally {
results.close();
}
} finally {
statement.close();
}
} finally {
connection.close();

Yeah, that should be closing itwould you be establishing the
connection(s) anywhere else though?
And do you have a ResultsSet that you're leaving open? You would need to
close that, too.
Same for any prepared or callable statement as well.

return statements do not prevent the finally block from executing:
http://java.sun.com/docs/books/tutorial/essential/exceptions/finally.html
I stand corrected...
Always understood as during exception handling... but you right it seems
I just cant bring myself to write code like that... feels un-natural...
I would still put return after the close... apologies...
Ok sinoea, what I thought was just s little slip turns out to be right... I
actually tested it... that finally does run as the method loses scope... I
actually wonder how they do that... I imagine a destructor in a C class
underneath Java... its interesting, but I got to tell you, you doing the all
the good text bokk stuff, but the code makes me feel uncomfortable...
Anyway... I think you got a threading problem...
You using static class and servlets are multithreaded
Rather do something like this...
CollectionBranch branches = new
BranchData().loadBranches(Data.getDataSource(), 1);
and get rid of the static methods in that BranchData class
ie make it thread safe... at the moment you have multiple threads in that
static method... and with that finally I really dont know... haha
and then...
results.close();
statement.close();
connection.close();
return branches;
Would make me happy... and handle those exceptions
} catch (SQLException e) {
branch.setErrorMsg(Dear User, you have run out of
connections);
}finally{
//absolute critical stuff
}
But that really is just a style thing from the looks of things... although I
do think that with just a finally, you will still get a ungly servlet
exception...
ie you are definitely cleaning up... but you not telling the user why... its
style
You doing all the good stuff... but more important even if you forget a
final or two... is just a nice clean readable flow... I think ;)
We have a style clash ;)
Anyway thing your problem may go away once its thread safe ;)
Thanks... learnt something ;)
Will keep guessing till we get it ;)

Re: Non-Heap Memory always increasing during deployment for TC 5.5.26/Solaris/JVM 1.5.0_16
I think you need to add one more line to your CATALINA_OPTS statement: -Dcom.sun.management.jmxremote=true If that does not help you, I'd try using port 6969 (the default) instead of . It should not matter, but I would at least give it a try as part of the troubleshooting process. You could also check to make sure you have access to the system on port , and that there are no firewalls (or iptables) in between you and the system preventing access to this port.

Tomcat 6.0 upgrade details
I am a Tomcat 5.5.x user and I am considering upgrading to Tomcat 6.0. In particular I am interested in knowing more about the details of changes made to Memory usage optimizations and Refactored clustering, two of the changes mentioned in 6.0. Performance and scalability are becoming important on my current project and I would like to know what upgrading will buy me. Does anyone on this list know?

Re: Can I get Millisecond precision in Access Logs?
It is. The docs are here:
http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/catalina/valves/AccessLogValve.html
I use
Valve
className=org.apache.catalina.valves.AccessLogValve
directory=logs prefix=unity_access.
suffix=.log pattern=%h %v %t %s %b %D %{RUNNING}c %r/
The AccessLogValve must be used and it is the %D spec that show
milliseconds.

Re: Can I get Millisecond precision in Access Logs?
Correct, I realized after I posted.
I guess you'll have to get the source code for AccessLogValve and roll
your own override...
I found this article via google accesslogvalve tomcat source
4th link:
http://www.devx.com/Java/Article/32730/1954 includes a source code
archive and the example in the article shows milliseconds on the
timestamp.
5th link:
http://www.docjar.com/html/api/org/apache/catalina/valves/AccessLogValve.java.html
is tomcat 6 source and you quickly see what to look for in the code:
874 timeFormatter = new SimpleDateFormat(HH:mm:ss);

(Apache + mod_rewrite + mod_proxy).

Re: [a little OT] Can I get Millisecond precision in Access Logs?
Mark,
Interesting but shouldn't the getDate method be slightly different:
if ((systime - currentDate.getTime()) 1000) {
In this line if currentDate is at millisecond 900 then the next second
starts with the millisec and that is 100 ms later.
long cachedtime = currentDate.getTime();
if ((systime - cachedtime 999 - cachedtime%1000) {
Yes, I know it is a quibble about what is probably fuzzy logic. But
I'm just a guy who learned to typeset using integers in ebcdic at 300
dpi in Fortran and IBM Sys 370 Assembler and this is a classic next
pixel problem with proportional width characters at a small font size.
(A comment for all those US-ASCII-7 haters - look up the EBCDIC code
table :-) or better look up Hollerith who invented Punchcards for the
1890 US Census. There is some logic to it that is very similar to
QWERTY...)

Re: Can I get Millisecond precision in Access Logs?
Does it have the %D reading? Also, I have seen on Apache web server that %D does not work properly for microseconds windows instead it is 15msec resolution due to windows timers. Basically not very usefull since some code is written correctly and is under 15Msec. I think I saw the same issue with Tomcat logging. Open source can run faster than commercial if you know what you are doing. I got Tomcat requests operating under 1 nanosecond at one point in time at the servlet level.

You are right this isn't perfect. I'd need to do some performance tests so
see how much slower the more correct code is. To be perfectly honest, I can
live with the current implementation and don't feel the urge to scratch
this particular itch.
Of course, that shoudn't stop anyone else who fancies taking a look at
this. Patches that improve the implementation without adding much (actually
any in this case) overhead welcome.

(duh) This will help: http://en.wikipedia.org/wiki/Named_pipe As Brantley points out, Debian is using a fifo (an object on the filesystem) to subvert Tomcat's usual, non-rotatable catalina.out output file and instead sending all those bytes to some other program for likely depositing onto the filesystem in nice, date-stamped files. Does the fact that the rotatelogs utility is also used some lines further down shed any light onto this ? Probably. I'm not familiar with 'rotatelogs' specifically, but it stands to reason that they'd create a consumer for all those log bytes expected to be streaming out to catalina.out after Tomcat starts. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkjQKyQACgkQ9CaO5/Lv0PB+HACfYxOO4+3+AZ+1qf5+SADSMXJV c7EAoKKX9kSrCf6+zp5j0Rvdj8oTAQVU =Ua3g -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How do you have your dev environment setup?
I've been doing a lot of webapp development on tomcat, but currently my process is all manual. I write the code in Eclipse, and then copy the appropriate files over to tomcat. I'd like to automate and standardize my process. So would y'all mind explaining how your dev environment is configured? I'd appreciate the insight. TIA.
RE: Balance and sync data
If you're expecting the size of your image store to grow, or better yet, grow rapidly, you'd be best served to consider a strategy either with mod_proxy/mod_rewrite, or better yet, looking into a CDN (content delivery network) to host the images themselves. Example, I'm about to launch an offering that will allow for our support team to publish video tutorials on how to use our products. It makes absolutely no sense to have a copy of each video file on each front end webserver (we use tomcat as the web server and application container), and it also isn't responsible to deliver a content offering with no redundancy in case of outage/downtime/disaster. Instead, we're leveraging some clever (but very easy) DNS, and Amazon S3 to host the files. By leveraging Amazon, we can link all our content by using a CNAME DNS record, like content.yourname.com , and automatically deliver that content from Amazon. Of course, there are drawbacks. I don't think this method would work in SSL implementations for instance. This link is to the instructions I followed ot deliver content via S3: http://www.carltonbale.com/2007/09/how-to-alias-a-domain-name-or-sub-domain-to-amazon-s3/ Paul McGurn -Original Message- From: Martin Spinassi [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 16, 2008 5:53 PM To: users@tomcat.apache.org Subject: Re: Balance and sync data On Tue, 2008-09-16 at 22:20 +0200, André Warnier wrote: [...] The question I've been holding back since your initial post, is why exactly you do want to load-balance similar requests to 2 Tomcats ? Just an idea : If it is because you have a) image stuff and b) non-image stuff, and they each represent about 50% of the load, then maybe you do not really want to balance (with the problems of sharing and/or duplicating the images), but you could just use a front-end to split the image stuff and send it to Tomcat-1, and the non-image stuff and send it to Tomcat-2. (Apache + mod_rewrite + mod_proxy). This way, only Tomcat-1 would need to handle the images (up and down) and it would always be up-to-date. They are all image stuff. The idea of duplicate those images are availability, just in case one tomcat goes down. But, in the other hand, images (and resize, thumbnails, etc) consumes resources, and the possibility of using just one server is still around my head. If the images load makes big enough, may be using another server just for that could be a good option. I've to read something more about mod_proxy, and see if I can apply it to resolve some load issues. Thanks for your help André, I'll keep your idea in mind to try it before selecting the right one to production. Cheers.

Re: How do you have your dev environment setup?
I use Eclipse with the Web Standard Tools plug-in. That lets me run and debug the app in Eclipse. When the app is ready to go I export it to a .war file and deploy the .war to the server. -- Len On Tue, Sep 16, 2008 at 17:59, Bai Shen [EMAIL PROTECTED] wrote: I've been doing a lot of webapp development on tomcat, but currently my process is all manual.

Re: Interapp Communications
Hi Johnny,
Thanks for your responses. I did read them on the day that you posted them but
only got a chance now to respond. Needless to say I have gone with a simple
HttpURLConnection solution, as my choice out of other suggestions given to me
in other threads, of using numerous other solutions including RMI, HttpInvoker,
JMS, etc. Eventually, the simple HttpURLConnection is nice and lightweight for
my needs right now. And now that the beast that is the Commons HttpClient is
out of the mix things are far more efficient.
Many thanks,
Darryl Pentz
P.S. Nice to see Saffers helping other Saffers :-)

Subject: Interapp Communications
Some time back I needed to communicate between two apps running in the
same Tomcat instance. I decided on using a simple HTTP call with Apache
Commons HttpClient. For some reason use of this class is causing PermGen
errors (I should add that I use a dynamic language in the mix, which might
impact that in some way) so I want to abandon that approach anyway,
because it just doesn't 'feel right' :-).
So I was wondering, is JMS the way to go with something like this? I see
Tomcat is able to use JMS via a JNDI read-only lookup.
Many thanks,
Darryl Pentz
Well, the way you doing it is also good for cross machine, cross domain
you using simple SOAP... Axis your way...
That HTTPd client is quite heavy, maybe Java's URL Connection will do what
you need
I dont bother too much with the stuff out there... JMS is a way, but you
looking for JNDI registries now.
Not sure if TC built in JNDI... targeting tomcat... will be enuf?
Some very rough code for you to play with... Java really makes http very
very easy
private byte[] loadURLFileBytes(String urlPlusFile) {
byte[] data = new byte[0];
try {
URL url = new URL(urlPlusFile);
URLConnection connection = url.openConnection();
connection.setDoInput(true);//GET
connection.setUseCaches(false); // get fresh from server
InputStream in = connection.getInputStream();
BufferedInputStream bis = new BufferedInputStream(in);
int length = connection.getContentLength();
int len;
byte[] buffer = new byte[512];
while ((len = bis.read(buffer)) != -1) {
data = appendBlock(data,buffer,len);
}
in.close();
bis.close();
} catch(Exception ex) {
//JOptionPane.showMessageDialog(null, ex.getMessage() , Error
during data download, JOptionPane.WARNING_MESSAGE);
return null;
}
return data;
}
That all your HTTP is doing for you...
Then Tomcat can do cross contexts as well... theres a cross context flag to
set and some code that looks like this..
The post also describes the issue...
http://forums.java.net/jive/thread.jspa?messageID=215873
One day when your site is huge, you making millions... maybe your cross
machine way will sound good again ;)
Theres SOA/EJB as well... ;)
Have fun...

You could use ant to automate it. I've tried deploying from eclipse to tomcat briefly. It seemed alright as well.
