Re: [OT] How much RAM can java use

I've tested 32/64 bit JVMs extensively and done considerable amount of JAVA_OPTS tuning for my company's application. On a 32-bit machine you can't reliably go above a -Xms=1600m without getting OOM errors. With a 3/1 split your virtual page table size for the entire JVM process must be below 3GB total virtual memory. That's 3GB allocated, not commited. The JVM allocates a lot more memory besides the heap. With the 64-bit JVMs, the sky's the limit, however the 64-bit address also make your application take up more space relative to a 32-bit JVM. A 3.2GB 64-bit heap space isn't going to double the amount of identical objects you can create as compared to a 32-bit 1.6GB heap space because all pointer references will occupy twice the space. -ryan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat Session Replication Question
Can somebody tell me if there is a way to determine when session replication is complete after a new tomcat instance joins the cluster? When updating our cluster we usually restart one tomcat instance at a time. What we noticed is if we restart the second one too quickly after the first rejoins the cluster some sessions are lost because we did not provide enough time for all the sessions to replicate.

Clusters - Disabling or restricting autodiscovery via multicast (security question)
When using tomcat clusters on an untrusted subnet or using a routable multicast address, i see the potential for a rogue tomcat instance to join a cluster in order to hijack session information. This doesn't seem to be cured by any firewalling of incoming connections to the valid servers, as, from what i have read, the valid servers will do a unicast conect to the rogue sever on the address/port specified by the rogue server's multicast transmission and will transfer session data to it. If this is incorrect, I'd be grateful for an explanation. If this is correct, Is there any way to restrict autodiscovery of cluster membership to a known list of IPs or disable auto discovery alltogether?

DeltaManager: calculation of deltas
I'm trying to understand how the DeltaManager determines the deltas of a session. From what I could find out by browsing the source code, there is no way to know whether a session attribute is dirty unless is it set again, e.g. HttpSession.setAttribute(Object obj). In other words, if the following piece of servlet code were serviced within the context of a DeltaManager, I could not expect the Count object to be broadcast to the cluster as a delta: Count count = (Count) request.getSession().getAttribute(count); count.value++; I would have to ensure that the following code were executed in order to broadcast the count attribute as a delta: request.getSession().setAttribute(count, count); 1. Are my findings correct? 2. If my findings are correct, where is the justification for this logic? Is there some specification or other official documentation that acknowledges that this is acceptable?

Re: Max thread/session timeouts
As a reference, in conf/server.xml I set my thread limit to 1 max threads, 1000 max idle threads, and 100 on startup. I've seen my as many as 7K threads busy within my application. This is on a 32bit 2.6 Linux kernel with 2GB of RAM (-Xmx1500m). On the 2.4 kernel I found practical limitations in how many threads the kernel could multiplex between, saw frequent system hangs under high load where the whole server would become unusable. On either linux kernel, you probably want to increase your maximum number of file descriptors in /etc/security/limits.conf for your Tomcat user account(s). 16K nofile as default works great for me. How much more memory you need really depends on your application. 500 threads isn't that much memory overhead, but if each thread goes off and creates a bunch of objects while it's working you'll need to assure heapspace is available accordingly. The short answer is: try it out, play with it. 500 threads isn't a whole lot. -ryan Kenneth Litwak wrote: We're running an application on Tomcat that often hits the limit of 150 threads.

Classpath issues with embedded tomcat
Hello all, I'm running embedded tomcat 5.5.9. Let's say that I have one version of X.jar in my main classpath when I launch my embedded Tomcat, and also a different version of X.jar in a deployed webapp under WEB-INF/lib. Is there a way to force tomcat to use the X.jar version that it's in WEB-INF/lib and NOT the one that's in the main classpath? The default class loading behavior uses the X.jar in the main classpath and not the X.jar in WEB-INF/lib, which is causing problems since the deployed webapp doesn't suppor the version of X.jar that the parent classloader has already loaded. Any help is greatly appreciated! Thanks, Ryan

Problem configuring context resource in embedded tomcat 5.5.9
Hello all,
I'm trying to manually configure a context resource using embedded Tomcat
5.5.9. I'm not sure if ordering is important in the code below, but perhaps
one of you could shed some light. I don't get any exceptions or anything,
but my webapp isn't able to find the resource. Here is the relevant code:
// - BEGIN LOAD CUSTOM WEBAPPS
try {
// Configure JDBC data source.
ContextResource ctxResource = new ContextResource();
ctxResource.setName(jdbc/juddiDB);
ctxResource.setAuth(Container);
ctxResource.setType(javax.sql.DataSource);
ctxResource.setProperty(maxActive, 100);
ctxResource.setProperty(maxIdle, 30);
ctxResource.setProperty(maxWait, 1);
ctxResource.setProperty(user, user);
ctxResource.setProperty(password, pass);
ctxResource.setProperty(driverClassName,
org.firebirdsql.jdbc.FBDriver);
ctxResource.setProperty(url,
jdbc:firebirdsql://localhost:3050/juddi?autoReconnect=true);
ctxResource.setProperty(validationQuery, select count(*) from
PUBLISHER);
NamingResources namingResources = rootcontext.getNamingResources();
namingResources.addResource(ctxResource);
tomcat-user@jakarta.apache.org
// Load and configure the UDDI registry webapp.
Context ctx = this.embedded.createContext(/juddi, getPath() +
/webapps/juddi);
ctx.setPrivileged(true);
this.host.addChild(ctx); // add context to host
ctx.getNamingResources().addResource(ctxResource);
} catch (Exception e) {
e.printStackTrace();
}
// - END LOAD CUSTOM WEBAPPS
---
All of the above code is executed after the root context is created and
initialized, and before the embedded tomcat engine is started. Any ideas?
Thanks!

img tag's src not working for image files in a JSP in tomcat 5.5
All, I've read quite a few articles on this issue and tried all the solutions given and none of them seem to be working. I'm using Netbeans 4.1 with Tomcat 5.5. My application is using the MVC patter so I have a controller that is using the request dispatcher to forward a request to a JSP page. Basically I have an application at the context /Company. I have all my images in a folder called img and all my JSP's in a folder called jsp. I've tried using relative paths to the image directory and the images don't show up in the browser however if I look at the URL it seems right. I right-clicked to get properties and copied the URL: http://localhost:8085/Company/img/image.jpg If I paste that into a browser I get a 404 error from Tomcat. However, if I take off the image name and do: http://localhost:8085/Company/img I get a listing of the image files. If I click on the link for the image image.jpg it opens the file in the browser and I see the URL as: http://localhost:8085/Company/img/image.jpg which is exactly the same as what I had manually typed in. Doesn't make any sense to me as to why it works one way and not the other. Possibly a permissions issue? Can anyone shed some light on why I can't get my image files to show up in my JSP pages?

Properly setting src attribute for an img tag in a JSP
All, Can someone at least let me know what the proper way to set the src attribute on an img tag is? I've currently used relative ../img/image.jpg and also the following: img src=%=request.getContextPath()%/img/image.jpg/ When using either I'm seeing the same URL show up at the browser when getting properties on the unfound image. I'm able to load that image in the browser using that path only after I've taken the file name off and see the directory listing. Then I'm able to put the image name back in and access the image. This is really getting frustrating as I can't get a single image to show up in any of my JSP's. I even tried creating a simple HTML page, not a JSP, with an img tag and that image can't be found either. Same type of case as mentioned in my previous post. It can't load the image from that URL. But as soon as I hack off the file name and get the directory listing I can then readd the file name and the file will load in the browser. Any clue?? I'm completely stuck on this one.

If I click on the link for the image image.jpg it opens the file in the browser and I see the URL as: http://localhost:8085/Company/img/image.jpg which is exactly the same as what I had manually typed in. Doesn't make any sense to me as to why it works one way and not the other. Possibly a permissions issue? Can anyone shed some light on why I can't get my image files to show up in my JSP pages?

SSL keystore with more than one key entry - which alias is used?
If the keystore that Tomcat uses contains more than one entry where Entry type = keyEntry, how does Tomcat choose which one to use when sending a certificate to the client? It seems as though the alias name is not significant - any alias will do. After some experimenting it seems it uses the first one found. Is this correct? Or is some other method used?

ConcurrentModificationException in 5.0.27
We discovered what appears to be a bug regarding a ConcurrentModificationException Tomcat 5.0.27. The problem arises when two web apps are deployed that are trying to interact with each other in some way. The exception isn't thrown when one of the web apps is taken out of the loop.

RE: Tomcat processes
Generally speaking, one process with a lot of threads should perform better than distributing the threads among multiple processes because you're not doing as much context switching and it's more efficient on caches.

Ryan Earl Systems/Network Engineer dynaConnections Corporation 512.306.9898 -Original Message- From: Iannis Hanen [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 04, 2005 12:01 PM To: tomcat-user@jakarta.apache.org Subject: Tomcat processes Hi everyone, I have a question related to the scalability and performance of Tomcat. Typically, when tomcat gets started, it creates one process that spawns all the threads required to answer the requests for all the deployed web applications. Let's assume that I have 6 distinct web applications to deploy on a tomcat instance. If tomcat runs on a single high end server machine (with multi CPU), I am wondering which approach would scale better: 1) launch tomcat once with the 6 web applications (the regular way) 2) create two server.xml files (one server.xml including 3 web apps, and another one containing the remaining 3), and start two tomcat instances (running on different port obviously) on the same machine. 3) Follow approach 2 except that each tomcat instance contains all 6 web apps (and some load balancer is put in front). In short, I am wondering if having multiple tomcat processes running on a multi CPU box would scale better than having a single tomcat process dealing with everything. Is there a way to tune up the number or tomcat processes from server.xml or elsewhere? I could not find anything related to the number of processes to spawn at all. In some app server, it is possible to create several process for the same application. Is there anything similar in Tomcat?

I don't think you lose anything, assuming your application works fine. You gain: * A 64-bit Sun JVM for x86-64. * SNMP monitoring of the JVM. * The ability to attach a profiling to a running JVM and see what all the threads are doing--useful for catching production problems as they occur.

If i do some math, we can calculate a rough estimate for the min heap (154 - 64)/25 = 3.6megs so basically, you'll need to multiply the number of webapps by 4 megs to figure out the heap setting. peter lin On 4/20/05, LeeAnn Pultz [EMAIL PROTECTED] wrote: when you say 50 threads, do you mean 50 separate web applications?

Further testing, when we added in debugging code that would spin up dozens of threads just to see if we could cause the tomcat to get the error if we started one application up and had tons of threads, showed that we could get 800+ threads with no problems (no outofmemory errors) and that the problem does not in fact seem to be specifically related to the number of threads the application creates. In fact, regardless of whether each instance of the application spins up 3 threads (real situation) or 10+ (debug code only) threads, we still get the out of memory error not when we hit a certain number of threads, but actually when we hit a certain number of servlets having been initialized. Testing a very simple servlet, I can start up 25 instances of the servlet with no OOM error. Testing our application's servlet, I can only start up 17-18 instances of the servlet before getting an OOM error.

For #1, the (portable, spec-friendly) way is to write a servlet or

Just make sure said webapp has a WEB-INF directory and a web.xml. Even
a web.xml of just
web-app/

Yea, I accidently hit the send button on the last email before I was done
writing it, but it's working. I just had to create two context files under
conf/Catalina/localhost/

Need help exporting contexts not under webapps/
Hello,
I'm in the process of bringing an in-house application up under Tomcat.
Previously we were using Jetty as the servlet container, but for various
reason I'm trying to get said application running with Tomcat 5.5.9 and Java
1.5.0.
The problem I'm having is that there are two directories with a large amount
of static files (pictures, videos, documents, and other forms of media) that
are mounted outside of the webapps/ home. Under Jetty, there is a
configuration directive that I can use to export these directories under a
URL path. I'm trying to do that in Tomcat, and the documentation has been
somewhat confusing.
What I've gathered is that this type of configuration should be put under
${CATALINA_HOME}/conf/context.xml however I have been able to do this
successfully. I've tried putting the following in context.xml but it gives
me errors:
Context path=/DOCS docBase=/mnt/CMFiles/DOCS
debug=0
/Context
So my question is, in short, given a directory structure of static files,
how do you get Tomcat to serve said static content off of an arbitrary URI?
Ideas?
Thanks in advance,
-ryan

Changing .systemPrefs location
All: I'm running various Tomcat instances on the same system, using the same JDK. One problem I'm running into is: * One web app is running as user1 * Another web app is running as user2 * Both web apps use the same JDK * Both web apps use system preferences * When one web app is started, it writes .system.lock, and .systemRootModFile, and won't allow the other web app to start cleanly because those files are not writable. Is there a way to tell one Tomcat instance to use /a/.systemPrefs, and the other to use /b/.systemPrefs to avoid this deadlock?

Re: Re: Out of Memory when compiling JSP (Struts app on Tomcat 4.1.27)
If you're nervous about registry work, back up your registry. Then open regedit and find: HKLM\SYSTEM\CurrentControlSet\Services\Apache Tomcat 4.1\Parameters (You can choose a different control set as well, and for Tomcat 5 users, this is under ...\Services\Tomcat5\Parameters.) You should see some Java startup options there already. They are named JVM Option Number x where x is a zero-based option count. The x *must* be incremented by one each time. If you skip a number, only the options before the skip will be loaded. e.g. If you set options 0, 1, 3, 4, and 5, then only 0 and 1 will be loaded. The rest will be ignored. Also, you must set the JVM Option Count key to the total number of options you have set. This will be one more than your highest option number. Think of it as an array where the options are the elements and the option count is the array length. I would guess that's how it's implemented. -Original Message- From: David Johnson[EMAIL PROTECTED] To: Tomcat Users Listtomcat-user@jakarta.apache.org Date: Thu Jan 06 07:40:27 PST 2005 Subject: Re: Out of Memory when compiling JSP (Struts app on Tomcat 4.1.27) Cool.

Probably the best way to troubleshoot out or memory errors is to see what is really happening with garbage collecting, the same way that you tune it. If you can add these options, then the JVM will spit out all kinds of useful information: -XX:+PrintTenuringDistribution -XX:+PrintGCDetails -Xverbosegc But it sounds like the problem is that it's not getting the options. What you really need to figure out is exactly how the service is getting started. For instance, if it's calling tomcat.exe then I don't believe that the JAVA_OPTS environment variable is ever looked at since that is in the startup.sh and startup.bat files (I'm not 100% certain about that however). Find out how it's starting. Also, post the version of Java you are using (since the options I gave you above don't work on all versions, I think 1.4 and up or 1.3 and up).

Re: web.xml servlet mappings, url pattern and CGI.PATH_INFO (tomcat 4.1.31)
I don't know anything about ColdFusion, but if I understand you right, you're
wanting to tack extra information onto a url beyond the file name and retrieve
it somewhere for use, like so:
http://server/context/index.cfm/someParam
Then the page is actually index.cfm, and when it is run it will be able to see
the someParam. Is this correct? If so, my first thought is a query string.
Can you use one instead of the above?
Next, here's why what you're trying to do with the url-pattern won't work. The
'*' in a url-pattern isn't actually a normal wildcard. There are only a couple
of specific ways it can be used:
1) /* or /something/* or /.../* - This is path mapping. When a request is made,
the longest matching pattern is used.
2) *.something - This is extension mapping. Anything with the extension you
specify will be matched.
(For full rules on url-pattern matching, see the Servlet spec, chapter 11.)
I suppose you could map a pattern like /cfm/* to your own servlet, which would
extract the file name from the path and request it from the cfm servlet and
also do something with your extra information.
This early in the morning, I can't think of a good way to do what you want
easily.

Subject: web.xml servlet mappings, url pattern and CGI.PATH_INFO (tomcat 4.1.31)
I am new to the J2EE world, so hopefully I will not use terms incorrectly.
Due to circumstances beyond my control, coldfusion has been retrofitted
into a J2EE web application and I have recently taken on the task of
trying to make previously existing cfm code work as part of a tomcat
installation. I have found (so far) only one thing that doesn't work
like it used to, and its a significant problem for me.
CGI apps can have a false path appended after the script name, which is
written into the CGI.PATH_INFO variable, so that it can be available to
scripts. It would seem that tomcat is less flexible than apache httpd
about when this information will be supplied. At least, jakarta-tomcat
4.1.31 doesn't want to play ball. I have not yet experimented with
version 5.x.
I have found a lot of discussion of this matter, but no conclusive
answer as to what the workaround is, nor, as i fear, that there is no
viable workaround.
By default, my coldfusion war file came with this in the web.xml:
servlet-mapping id=macromedia_mapping_3
servlet-nameCfmServlet/servlet-name
url-pattern*.cfm/url-pattern
/servlet-mapping
attempting to browse (via the coyote thingie) to
http://{server}/cfusion/htdocs/index.cfm
will bring up the right page, but
http://{server}/cfusion/htdocs/index.cfm/fake_path
this gets me a 404.
So far, I have only found one way to make tomcat give me the correct
PATH_INFO -
If I do this:
url-pattern/htdocs/index.cfm/*/url-pattern
then I will be able to run the right script and CGI.PATH_INFO is set to
/fake_path.
Naturally, if you have more than a couple situations where you use
PATH_INFO, this configuration becomes quickly unmanageable, and
unreasonable. (grep -iRl path_info . will only get me so far)
Is there a way to make this work without naming every cfm file that
might use PATH_INFO in the web.xml?
For anyone interested in helping, here are some things that I have tried
that did not work (in each case, I have tried it as a replacement,
breaking the normal way it works for possible experimental value, or as
an additional servlet-mapping):
If I do this:
url-pattern*.cfm/*/url-pattern
I get an error in the jakarta logs when the web.xml is read;
java.lang.IllegalArgumentException: Invalid url-pattern *.cfm/* in
servlet mapping
I looked up the source code and it says you can't start a servlet
mapping's url-pattern with *. and have a / in the pattern at once. :/
If I do this (nevermind that its not exactly what I want):
url-pattern*.cfm*/url-pattern
Then the second * is not expanded as a wildcard. i.e. a file named
index.cfm* (literal '*' character) could be processed as a cfm file.
If I do this
url-pattern/*.cfm/*
I get a 404.
Thanks in advance for any time that any of you spend considering this issue,

kaffe and tomcat 5.5.4
I'm running tomcat 5.54 on the free kaffe vm instead of Sun's JDK. When I start tomcat with the startup.sh script as root, everything runs perfectly. However I'm having trouble launching the process with JSVC. Does anybody know if JSVC can be made to work with java VMs other than SUN's? Jsvc debug output says it cannot find the file jvm.cfg, and also the actual vm file library names from the sun jdk appear to be hard-coded into the jsvc source because they cannot be found in the kaffe vm as well. If anyone has any helpful information, I would be most grateful. It is disappointing that Tomcat 5.5.4 runs perfectly on Kaffe only to be stopped by limitations in the commons-daemon...

SSL mutual authentication problem with Tomcat5
Hello, I'm trying to have a standalone Java client communicate via SSL with a remote Tomcat5 server. I'm setting the two system properties for specifying the SSL trust store path and trust store password. The client is able to successfully communicate via SSL when Tomcat is configured to not require client-side authentication (for example in tomcat the configuration attribute 'clientAuth=false' would be used). However, when I turn on this attribute and require client-side authentication, the client fails to communicate successfully with the Tomcat5 server. The following exception is generated: java.rmi.RemoteException: HTTP transport error: java.net.SocketException: Software caused connection abort: recv failed; nested exception is: HTTP transport error: java.net.SocketException: Software caused connection abort: recv failed at . Is there anything else that must occur on the client side when the remote web server requires a client-side certification authentication? I'm still new to SSL, so perhaps I have the basic concept confused. Do I have to import another certification in the client-side keystore for this to work? I looked in the SSL HOW-TO but didn't find an answer to my question. I also tried importing all of the certificates in the client keystore into the cacerts file in JAVA_HOME/jre/lib/security/cacerts. Here is the connector configuration for SSL in server.xml: !-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -- Connector port=8443 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 debug=0 scheme=https secure=true clientAuth=true sslProtocol=TLS keystoreFile=C:\ssl\sslWSCerts.keystore keystorePass=changeit/ Thank you for any help that you may be able to provide. -- Ryan

Subject: JNDI / pooling
Hi,
I can't describe exactly the problem because I'm not familiar with all the
terms... But the big picture is that I want to create a pool of ftp
connections to work like a database connection and I want to get the
connection from JNDI.
So far I extended BaseKeyedPoolableObjectFactory and StackKeyedObjectPool
and it works fine like this:
FTPConnectionPool pool = new FTPConnectionPool();
String key = key;
try{
FTPClient ftp = pool.borrowClient(key);
if( ftp.sendNoOp() ){
System.out.println(OK);
}else{
System.out.println(NOPE);
}
pool.returnClient( key, ftp );
}catch(Exception ex){
ex.printStackTrace();
}
But I want to make it work from JNDI almost like a datasource
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)
ctx.lookup(java:comp/env/jdbc/backup);
Anyway I am completely lost if it can be done or not.
So far I get an exception when I try to start Tomcat:
GlobalResourcesLifecycleListener: Exception processing Global JNDI Resources

Hi Ryan,
I should have asked this earlier, but are you using the RPM version of
Apache or compiling the source tarball ? I notice that your directory is
/usr/local, which indicates that you are probably using the source tarball
(for RH9 rpms, it would be /etc/httpd).
If you are using the source tarball, there are a LOT of things that are
different. I believe you are missing a package, hence the gdbm error. I
cannot recall at the moment what the name of the package is -- can you do
a search on rpmfind ? Another thing: apxs is located inside
/usr/local/httpd-2.0.49 -- just do a find /usr/local/httpd-2.0.49 -name
apxs to locate it.
Did you do a Minimal install for Red Hat ? You will need to ensure that
you have the necessary packages installed. See this for a short list :
http://cymulacrum.net/writings/tomcat5/c875.html#JK2_INTEGRATION_SETUP
You probably don't need apr and apr-util because you installed Apache from
source.
As promised, here are my notes on installing mod_jk2 with Apache
2.0.49 and Tomcat 5.0.25. This is under RedHat 9.0 and the paths and
things are a straight cut and paste from my system here, so may not match
up for all accounts. Key problem I had was the libraries, once that was
figured out it was some minor typos in the configuration files, and then
its all up and going now.
Cheers,
Ryan.
Notes --
mod_jk2 (tomcat connector)
Download mod_jk2
http://apache.ausgamers.com/jakarta/tomcat-connectors/jk2/source/jakarta-tomcat-connectors-jk2-2.0.4-src.tar.gz
Check the
http://apache.ausgamers.com/jakarta/tomcat-connectors/jk2/ page for
information/status on mod_jk2
Uncompress the archive
gzip -dc jakarta-tomcat-connectors-jk2-2.0.4-src.tar.gz |

edit ./server/apache2/Makefile
Find the block --
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
endif
And change it to this:
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
JK_LDFLAGS=-lcrypt ${APR_LIBS} -L/usr/local/httpd-2.0.49/lib -laprutil-0

endif
Note the extra LDFLAGS -- JK_LDFLAGS=-lcrypt ${APR_LIBS}
-L/usr/local/httpd-2.0.49/lib -laprutil-0 -lgdbm -ldb-4.0 -lexpat
To know what flags to add, run
apu-config --link-ld --libs
That will output something like
-L/usr/lib -laprutil-0 -lgdbm -lexpat
Then check the version of apu-config. I discovered that I
had two versions. One in
/usr/bin and another in /usr/local/httpd/bin/
/usr/bin/apu-config --link-ld --libs

-L/usr/local/httpd/bin -laprutil-0 -lgdbm
-ldb-4.2 -lexpat
When I tried adding the -ldb-4.2 flag it didn't like it,
so I did a bit of a search and tried
-L/usr/local/httpd/bin -laprutil-0 -lgdbm
-ldb-4.0 -lexpat
instead which worked. (I think the path for db-4.2 may
need to be added to my /etc/ld.so.conf file?)

The second app has been running for a couple weeks and did not hang at first but has started to hang once in awhile and it appears to be happening more frequently. This does not seem to be related to usage as neither app is getting a lot of traffic when they go down. Here's our setup: Red Hat Linux 9 Apache 2.0.49 Tomcat 5.0.19 Java 1.4.2 we are using mod_proxy to forward requests from apache to tomcat. It went down this morning and we did a thread dump as was suggested elsewhere and couldn't find anything that was suspect. There is nothing in catalina.out to indicate why this is happening. Someone here suggested that perhaps it has something to do with writing to catalina.out. This is legacy code and catalina.out is used for logging. The previous developers are logging every single SQL statement to catalina.out. This file is getting very, very large. Could this have anything to do with it? Any help on this would be greatly appreciated as our customers are getting more and more annoyed. Thanks.

RE: Tomcat 5.0.x deadlock
Hi, Does Tomcat stop responding on both RedHat 8 and RedHat 9 or just the one on RedHat 9 ? Ryan. -Original Message- From: Stefano Lissa [mailto:[EMAIL PROTECTED] Sent: 08 June 2004 13:31 To: Tomcat Users List Subject: Tomcat 5.0.x deadlock Hi, this my situation: two indipendent servers, the first with red hat 8, jdk 1.4.1, tomcat 5.0.16, no connectors, no Apache. The second with red hat 9, jdk 1.4.2_04, tomcat 5.0.19, no Apache. Randomly I find Tomcat stop responding: no CPU load, no JVM activity, no information on catalina.out and localhost_log. No one web app respond, even the manager is not accessible. This situattion is not connected to a high load, on a server I have no high load at all. It seems a server deadlock... the only way to recover is to restart tomcat. Same situation? Some ideas? I haven't changed tomcat jars, they are clean installations. Can I setup Tomcat on a way to track what happen? Thank you.

RE: Tomcat 5.0.x deadlock
It is more than likely a problem with the NPTL stuff that was included in RedHat 9. Setting the LD_ASSUME_KERNEL environment variable to 2.4.1 will probably fix your problem, so in /etc/profile (or equivalent) add: export LD_ASSUME_KERNEL=2.4.1; There are plenty of details about this in the archives ...

Custom Authenticator for Flash Remoting?
I am writing a custom authenticator for flash remoting. Flash remoting uses a binary message format that is stored in the request body, and it has its own credentials header in the message. That means I have to read the body from the inputstream in the authenticator to retrieve the credentials, but the gateway Servlet that actually processes the message also needs to read the message from the request body. Is there any way to wrap the HttpRequest from an authenticator so I can read the input stream in a buffer and hand a buffered input stream on for the Servlet to process? I tried to override the invoke method of Authenticator hoping that I could wrap the request from there and then call super to hand it along to AuthenticatorBase, but this threw an exception. Any Ideas? --Ryan

No, you misunderstand. Port 8080 is the unsecure port, so trying to access it with https gives a cannot find server error. That's my problem.

Subject: value for useBean class attribute invalid
Hi there,
I'm trying to set up a simple beans backed jsp application. I set up
everything, the bean compiles, the context for the web app is set.
*snip*
package my.packages;
public class PrimitiveBean implements java.io.Serializable
{
String content = PrimitiveBean says hi!;
PrimitiveBean() {
}
*snip*
One problem I see is that your constructor isn't public, therefore the bean can't be
instantiated by any class outside the package it is in. If that's not the problem, I'd
make doubly sure your WEB-INF folder is being picked up correctly.

I've been trying to install the mod_jk 2 module statically into Apache

looked around and mostly find that people use the so module way of
installing.

RE: Tomcat having strange 'hickups'
Hi, If it is running on a machine with multiple CPUs, you can use the concurrent collector. The collector then runs on one of the CPUs while the application continues to run on the others, the other threads will still be suspended for a short period (during the marking phase) but it can be an improvement. Note that there is a trade-off in that the collection will typically take longer. First things first though, you should tune the size of the total heap and, importantly, the size of your young generation. This has a very large impact on garbage collection performance. You will of course have to profile you app and test extensively to find the best settings for your application. I found the following links to be helpful: http://ph.sun.com/events/presentation/files/java_tech_day/hotspotperformance .pdf http://www1.sitraka.com/JUG/meetings/presentations/sep02/JUG%20Sept%202002.P PT http://java.sun.com/docs/hotspot/PerformanceFAQ.html http://www.javaperformancetuning.com/news/qotm026.shtml http://www.run.montefiore.ulg.ac.be/~skivee/java-perf/j2se141-gc-options.php http://java.sun.com/developer/technicalArticles/Programming/GCPortal/ http://java.sun.com/docs/hotspot/gc1.4.2/index.html http://java.sun.com/developer/technicalArticles/Programming/turbo/ http://www.javaworld.com/javaworld/jw-03-2003/jw-0307-j2segc.html http://performance.netbeans.org/reports/gc/ http://www.tagtraum.com/ http://jakarta.apache.org/tomcat/articles/performance.pdf Regards, Ryan. -Original Message- From: Wojciech Sobczuk [mailto:[EMAIL PROTECTED] Sent: 13 May 2004 17:51 To: Tomcat Users List Subject: Re: Tomcat having strange 'hickups' It is possible.

I noticed it when browsing one of my sites, everything was working fast, and then at a certain point, after I clicked on a link, the browser started connecting to the server and waited for the response for a long time. When I checked the load on the box it was 1-2 (normally it's 0.5), but didn't notice any processes hogging the CPU with 'top'. I already fixed all DB connection leaks I had so that can't be the issue here. Traffic peaks can't be it either, I have constant traffic. I know that this isn't a precise description of the error I'm encountering but I don't have any more information at this point. I'm hoping that someone encountered this already and can help me, or perhaps you can give me directions how to figure out what's wrong. Best regards, W.

RE: Off Topic - Java Graphing Package

I am going to use it within Tomcat, but I could probably use something that's aimed at applets if I had the source code. Thanks to anyone who responds.

RE: Tomcat 4.1 HttpServletRequest.getServerPort() returns incorre ct port ?
Hi Bill, Thanks for the clarification. Best regards, Ryan. -Original Message- From: news [mailto:[EMAIL PROTECTED] Behalf Of Bill Barker Sent: 12 May 2004 07:22 To: [EMAIL PROTECTED] Subject: Re: Tomcat 4.1 HttpServletRequest.getServerPort() returns incorrect port ? Ryan Lissack [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, In our setup we have a hardware load-balancer which forwards normal requests to our cluster of Tomcat servers. For SSL requests, the load balancer first forwards to an hardware SSL accelerator and then on to one of our Tomcat servers. Each Tomcat instance has 2 connectors configured. For normal requests, clients connect to load balancer on port 80 and the load balancer then forwards the request to a Tomcat instance on port 8800. For secure requests, clients connect to the load balancer on port 443, the load balancer then forwards to the SSL accelerator and then the load balancer forwards to a Tomcat instance on port 8801. The problem I am having is that the getServerPort method *always* returns 80 for all requests even though I know they were received on either port 8800 or 8801 (netstat also confirms this). If I connect directly to the servers (http://server:8800), the port is correctly reported. I can access the correct port by inspecting the incoming requests using reflection (request.request.connector.port) but this is obviously far from ideal (non-portable etc). Does anyone have an idea why this is occurring or perhaps a way around the problem ? This is occurring because getServerPort returns the value that the request was sent to (i.e. the value in the 'Host' HTTP header). This is necessary so that it is possible to form URLs that refer back to the server (e.g. response.sendRedirect). The way around the problem is to upgrade to Tomcat 5, and use request.getLocalPort. This returns the port that the request was received on. Thanks, Ryan.
