Re: Java and tomcat issues
'which' on checks the PATH variable,
type: echo $JAVA_HOME
and you will be able to verify you set that.
I think then you have to add that to your path
PATH = $PATH:${JAVA_HOME}/bin or something like that.

Re: tomcat 4.1.27 log4j problem
if you use log4j on a tomcat-wide basis (ie 1 configuration for the tomcat runtime and all your webapps), place your log4j.xml in [tomcat-home]/shared/classes/ if you use log4j on a per-webapp basis, make sure the log4j classes aren't on the tomcat classpath and configure commons-logging to use jdk logging (assuming you are using jdk 1.4).

RE: how to suppor 30000 concurrent users
With that many users you are going to HAVE to cluster if for no other reason than to provide backup for system maintanence. As to how many, the answer is it depends on the hardware you are going to use and the types of load your webapp puts on the system. When you say 30k concurrent users do you mean 30k people clicking a link at the same time or 30k active sessions at a time? If you are going to have this many people clicking on the same time you should have the cash to do proper load testing to see how many people one of your servers can take, divide 30k by that number for the number of servers you have, multiply by 1.1 AT LEAST and round up to get 110% capacity so you should be able to swap out one server. This is BARE minimum.

Servlet BufferedOutputStream Question?
Someone PLEASE Help!
I have been having hassles when using a BufferedOutputStream to send multiple images
from an Oracle database to the client. The error that I am getting is in the While
loop that sends the image as a byte[] to the client. java.net.SocketException:
Connection reset by peer: socket write error. What I think is happening is that the
first image is been sent to the browser and thereafter the connection is closed! Is
there a way to send multiple images out to the client in a single Servlet (Possibly
using a buffer). P.S The reason why I am not using IMG tags and sepecifying the
source to point to another JSP or Servlet is because I am doing some timing methods in
a single Servlet that writes out to a file.
Thanks for your help.

RE: XP random tomcat crashes
Hi David, The following might be of use to you: We recently had a struts-based application that crashed seemingly randomly, and after a lot of work and debugging we tracked it down to a bug in the JVM (we were using Sun's 1.4.1 JDK ). It was reproduceable on several platforms (HP-UX, Linux, win2k). We were not getting any dumps either on some of the platforms, the process seemed to just hang. Note: testing showed IBM's JDK didn't exhibit this behaviour, but Blackdown did. A workaround for us was to add the following parameters to Sun's 1.4.1 JVM: -Xint Operates in interpreted-only mode. -XrsReduce usage of operating-system signals by Java virtual machine (JVM). A fix for us was to upgrade to JDK 1.4.2 For more info, try posting the VM messages you are receving here.

RE: how to suppor 30000 concurrent users
I would also do a serious reality check on the 30,000 concurrent users number. After going through something like the drill below you will find that you have architected yourself one big system. The sticker shock alone might be enough for people to go back and seriously reconsider their numbers. Marketing people are sometimes on crack. Bigger sites (like eBay) work on seperating their services. So their frontpage is static and gets updated every so often. The second you search you are thrown to another server that just does searches. When you want to buy/bid you move to another server that just does that. -e On Tue, 5 Aug 2003, Ralph Einfeldt wrote: build a model like - each user is on the site for n Minutes - each user makes n requests - the mean time between to page requests is n seconds - each page request creates n http requests - specify the average size for an http request - specify the average ratio of request/db access . With that you can compute memory usage, requests/per second, concurrent databae connection etc. With these number you have to test your application (not tomcat) and see what your application can handle. There is no rule of thumb.

Howdy,
This is a separate issue, how to measure an object (or object graph more

measurement is not trivial. There have been discussions on the list, as
well as some good articles (I recall one on JavaWorld about 2 years ago)
on how to do this.
You should do this with a fixed heap size, i.e. -Xmx=-Xmx, and a fixed
young generation size (I forget the JVM parameter name). You should
call System.gc() before and after the test, but that's just a suggestion
to the JVM and doesn't really matter: this is why N should be high, to
offset the gc effect. And you will end up with an average that's an
estimate. The test keeps MyObjects allocated and does not release them
(until it's done) on purpose.

Hi,
it appears freeMemory is highly not to be trusted ;-):
Here is the free memory after each 1000 objects created:
#:717000
#:320080
#:1152992
#:512992
#:266208
#:1784800
#:1144800
#:504800
#:389088
#:3894240
The more objects I create the more memory I get ;-). In addition, how
can
the garbage collecter still collect any of these objects, if I have
stored
them in an array or is it collecting other objects (??)?
[ testing testing ]
ok after some more tests, it appears freeMemory keeps on returning
different results because it allocates more and more memory as more is
consumed. I ran the taskmanager and looked at the footprint, here is
what
it gave me:
no objects - 6 MB
5000 objects- 9MB (3MB for 5000 objects)
1 objects - 12MB (6MB for 1 objects)
2 objects - 18MB (12MB for 2 objects)
This seems to be pretty accurate, about 629 bytes per object (still
seems
low for what I am creating ;-)).
I rewrote the testing procedure to see if I could come up with the
same,
here it is:
System.gc();
int N =1;
int valid = 0;//count object creations that did not cause
additional memory to be allocated by the VM
long last = -1; //free memory during last run
long current = 0; //free memory during current run
long usedup = 0; //total memory used up by all 'valid'
allocations
Object workers[] = new Object[N];
for(int i = 0; i N; i++) {
workers[i] = new MyObject ();
current = Runtime.getRuntime().freeMemory();
if (current last) { //if allocation is deemed valid update
administration
valid++;
usedup += last-current;
}
last = current;
}
System.out.println (Footprint in bytes:+usedup/valid);
Result 640 bytes. I hope it is not a coincidence ;-)

Not exactly: I wouldn't put non-serializable objects in the session at
all, regardless of their size. You will get errors. Instead, put the
ID (or some other key allowing you to retrieve the object) in the
session.
In addition does anybody know how I can accurately estimate the

The same way you estimate the memory footprint of any other object.
For example, from a simple command-line program that does nothing
else:
int N = 1;
long freeBefore = Runtime.getRuntime().freeMemory();
MyObject[] myArray = new MyObject[N];
for(int i = 0; i N; i++) {
myArray[i] = new MyObject();
}
long freeAfter = Runtime.getRuntime().freeMemory();
long delta = freeAfter - freeBefore;
long memPerObject = delta / N;
(Use a large N to reduce impact of overhead, allocation, etc.)

RE: Jasper, JSPC, Ant and Precompiling JSP's
Mark,
The jspc task that I used from the standard Optional Tasks that come with ant, does
support a webapp parameter, and this works
fine to compile the whole webapp without any regexp voodoo ( I didn't use it because
it won't allow you to exclude any files ).
I did see once a conversation on the ant-dev list that complained about how brittle
the jspc task has been to maintain.
So jasper ( with 4.1.28 ) comes with it's own built in task to completely compile a
webapp. As described here :
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html#Web%20Application%20Compilation
If you ignore the part about the web.xml fragment, and make sure your output dir is
the same as your Tomcat workdir, then this works
too ( I think - I did so many experiments my mind is now cloudy ).

Subject: RE: Jasper, JSPC, Ant and Precompiling JSP's
That is EXACTLY what I am trying to do today. I've tooled around in the ant code,
and it seems this is more of a jasper
issue than
an ant one, because ant passes a long list of files to jasper, with the unwanted
pathnames that end up as part of your
package name.
I'm pretty sure if you used something like foreach to iterate through the same
fileset that is being created in the
jspc task, and
called jspc for each directory individually, and used the package=org.apache.jsp
attribute, then this would work -
because then
jasper wouldn't know about you're own subdirectory. But this seems ugly so I
haven't actually done it yet.
You can use the webapp element inside jspc, but then jasper doesn't know about
your exclude and so tries to compile some
fragment.jsp type include files, that are not really full jsp files, and so it
crashes on those ( this is my current
problem ). But
if all your included files are called .inc rather than .jsp then this may work.
jspc
destdir=${webapp.workdir}
failonerror=false
classpathref=jspPreCompile.classpath
package=org.apache.jsp
compiler=jasper41
webapp basedir=${webapp.path}/
exclude name=**/WEB-INF/**/
exclude name=include/**/
/jspc
So now I'm trying to make an ant step or task to replace the first line of every
generated _jsp.java file with the
correct package
name, between generating them and compiling them.
Plz met me know if you have something better.

Re: Behaviour of JSP with tomcat 4.1.24
AFAIK, Tomcat saves sessions across restarts. One of the gurus may have
the specific answer as to how you can disable this, I believe it has
something to do with whether your session attributes are serializable or
not.
You can just clear out the work directory between restarts. My shutdown
scripts have a rm -rf $CATALINA_HOME/work/* in them so that it is done
automatically. This can cause a slow startup, since Tomcat has to
recompile JSP again when they are accessed, but I restart Tomcat so
rarely (maybe 2-3 times a year) that it really doesn't affect my
instances all that much.

Hi All,
When we start tomcat and connect to the server, the index.jsp page is

to the next jsp page(login.jsp)
I stop tomcat and restart it again. Now when I connect to the server,
the index.jsp directly takes me to the login.jsp page without asking for
password. This should not happen. Everytime the tomcat is stopped 'n
started we should get the password validation.
But when I stop tomcat and clear the contents of
$CATALINA_HOME/work/StandAlone/,
When tomcat is started, it displays the index.jsp which asks for
password validation.

Tomcat v4.0 Admin Utility Crashing

RES: Where can i set Groups and user roles?
Ok, thanks! At this moment, I will try to use MemoryRealm. My last doubt is: does my application know the user role automatically whenever the login process have finished (role comes together)? Or not, my app should ask for authorization later... So ( automatically option ), the app could choose what view the user will deal with. Thanks Murray. -Mensagem original- De: Murray [mailto:[EMAIL PROTECTED] Enviada em: segunda-feira, 4 de agosto de 2003 22:26 Para: Tomcat Users List Assunto: RE: Where can i set Groups and user roles? Euclides, Try starting tomcat then look at the examples at http://localhost:8080/tomcat-docs/realm-howto.html. You can assign roles to users based on any of the three realm types but the mechanism is different in each case. I have implemented the JDBC based realm model and have a table in my database which has two columns: user and role. A user may have more than one role in my implementation and I have used the request taglib to ask req:isUserInRole role=leader to determine whether or not to display particular parts of a page. If the user has a row in the table with role set to leader access is allowed. Note that I discovered it is essential that all protected pages need to belong to some generic role first before you can gain access to the page to make the test above. Thus, if a user is to pass the above test, he must have at least two entries in the role table: one with member and one with leader. The member role permits access to the secure part of the website (as defined in the web.xml snippet below) and the leader role provides additional access controls. security-constraint web-resource-collection web-resource-nameScoutGroup-Secure/web-resource-name url-pattern/members/*/url-pattern /web-resource-collection auth-constraint role-namemember/role-name /auth-constraint user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint /security-constraint Murray -Original Message- From: Jose Euclides da Silva Junior - DATAPREVRJ [mailto:[EMAIL PROTECTED] Sent: Tuesday, 5 August 2003 06:01 To: '[EMAIL PROTECTED]' Subject: Where can i set Groups and user roles?

performance question
Tomcat 4.0.6 Solaris 8 Java SDK 1.4.2 We have a web app that is slightly slow. This is a problem because it is just a bit slower than the app it is supposed to replace. This has the customer upset, partially because we all hate change, but also understandably, the customer wants it faster. We had a third party build the application but we will maintain it. For whatever reason the company that built it will not be providing any more support as to how we can make it go faster. We have looked at the box, and it does not seem to be taxed. We have tried setting CATALINA_OPTS to maximize performance but tomcat does not seem to be using the additional memory and the system's load average remains low. Is there any way we can have tomcat use more resources, as much as necessary to run the application faster? On a side note I can find no documentation that explains the difference between JAVA_OPTS and CATALINA_OPTS? Also, we tried upgrading to 4.1.24 yesterday on another test server. The application will not run correctly on the newer version of tomcat, any ideas why? The results of the queries are not correct and the data is not returned correctly. Is there any major change in tomcat 4.1.24 from 4.0.6 that would cause such a disparity. Thanks, -Mark

Hi, This problem bought to the user list after it became evident it was a configuration issue and not a development one. Can anyone tell me why my session cookie is being invalidated when I close a popup window (the original remains open), either by window.close(); (Javascript) or the Windows close Ap. icon on the top right corner? Note: running the app. (and closing the popup) from the same instance of Tomcat, but from a different terminal does NOT do this! This would imply it is an IE config issue? Does anyone have any experience of this please? Thanks Paul. where my session was being invalidated OK, Thanks for that. An interesting note however..after some testing, the session is not killed when run from another terminal i.e running the same instance of TC (same server) but from different terminals. That would suggest it is an IE configuration issue (at much annoyance to certain developers). I will at this stage bring this up on the user list! Thanks Paul. i had the same problem with internet explorer. mozilla seems to work properly. i tracked the problem down and found out that internet explorer looses the session cookie when closing the popup browser window. then i added DefaultContext cookies=false / to my virtualhost definition in server.xml to disable the session-cookie mechanism. after that everything worked fine for me. remember to encode all urls with response.encodeURL(). jochen schwörer Wednesday, August 6, 2003, 6:00:57 AM, you wrote: PW Dear all, PW May someone enlighten me on why my session is being invalidated PW when I close a browser window?
