RE: FW: After manager says that there was a leak, how to use a profiler?
Solved: I had several contexts in my server, in each one was already a WAR created days ago. I forgot about all these old WARs. Since I took off my JARs from the shared/lib directory, all these old WARs could not work because they didn't include the JARs inside. So basically I was trying to run the new WAR and it worked, but I was still watching in the log the output of the old WARs trying to deploy and work, but failing. > -Original Message- > From: Brian [mailto:bbprefix-m...@yahoo.com] > Sent: Wednesday, November 17, 2010 11:35 PM > To: 'Tomcat Users List' > Subject: RE: FW: After manager says that there was a leak, how to use a > profiler? > > I have notices several weird things: > > - Sometimes it runs, sometimes it doesn't > - When I'm in Eclipse, if I already started the Tomcat server and it is running, if > I ask to run it again, it does without any error messages in the log > > It looks like if it was a syncronization issue.

Re: Problem in accessing jsp:useBean
*Your code:
<%@ page import = "beans.*, java.sql.*"%>
*
I think the value for class should be "beans.PasswordEncryptService". Class
should be "package.class". That's what I remember.

Hi,
I have installed tomcat-6.0.20 and postgresql-9.0.1
I have created a java bean PasswordEncryptService.java
I have kept it in WEB-INF/classes/beans directory and in beans
package.
I compiled the java file and successfully ran the class and could
enter a data in a table in pgsql database.
I have created a jsp file under webapps/apps/InfoMgmt/secure
directory.
In this jsp file I imported the PasswordEncryptService class and used
the
bean under the tag jsp:useBean. But I am getting the following error.
The value for the useBean class attribute PasswordEncryptService is
invalid.
Can anybody please, help me in resolving this issue?
Thanks and Regards,

configuring the tomcat-6 to support list of user certificates
Hi, Can anyone give some idea to configure the tomcat-6.0.18 to enable SSL ( https ) and also to support the list of user certificates to access a sample web application I have the user certificate and also the CA certficate , I have checked the docs of tomcat but i was not clear to configure it if we have both user and CA certifcates Thanks & Regards, shashi
RE: FW: After manager says that there was a leak, how to use a profiler?
I have notices several weird things: - Sometimes it runs, sometimes it doesn't - When I'm in Eclipse, if I already started the Tomcat server and it is running, if I ask to run it again, it does without any error messages in the log It looks like if it was a syncronization issue. Something like these: "If nothing is running, it will wait when I ask it to start. But of something is already running, maybe it will run.

It doesn't work either in the Tomcat installation at my production server, or the Tomcat local installation that my Eclipse uses when running the app. One interesting thing is happening though. Now it is showing the error messages in the log when I run it on Eclipse, but then IT WORKS!

That is not the problem, because as you said there is the WAR file that
expands, and other files there (.jsp for example) are reachable

Yes, I did, even though I read somewhere that if the JAR files are found in
"WEB-INF/lib", they are read from there before the "/shared/lib"
directory, if present at both places at the same time.

Well it will actually replace one line of code with another. In fact

The problem is, that I don't always run my processes in a tomcat, in
fact most of the time they don't (hence the OT).

Hi,
I have a ugly issue I'm sure many people on this list already solved.
For multiple purposes I need pid's of processes, to stop/start them or
ensure they are running. So far nothing spectacular.
To obtain the pid I have following util:
String[] cmd = { "/bin/bash", "-c", "echo $PPID" };
p = Runtime.getRuntime().exec(cmd);
and afterwards read the ppid from the output stream of my process. So
far - so good.
The problem now occurs if a process has a lot of memory configured.
Like 25Gb on a 32Gb machine. In such a configuration the above command
fails with an OS'es out of memory, because fork
fails to create another process with THAT amount of memory:
1598388 2010-11-17 02:54:47,061 ERROR net.anotheria.util.PidTools -
Could not determine PID: java.io.IOException: Cannot run program
"/bin/bash": java.io.IOException: error=12, Cannot allocate memory
Is there another method to obtain the process id from within the
process?

Leon

[2] http://blog.igorminar.com/2007/03/how-java-application-can-discover-its.html
I like the following:
int pid = Integer.parseInt( ( new
File("/proc/self")).getCanonicalFile().getName() );
There are others as well.

Pid, Andre
thanx.
I will try both approaches.
I will try the MX Bean first, this just seems to be more elegant ;)
Typical Java thinking..
Sure, let's pull in another 15 classes..
Gotta use those GB of RAM for something..
Why do simple when complicated would do just as well, he ?
:-)
While you're at it, here is another variation of the original scheme, much more to my own
liking :
String[] cmd = { "/usr/bin/perl", "-e", "print getppid(),\"\\n\";" };
p = Runtime.getRuntime().exec(cmd);
Same defect as yours though, damn.
Or (from the same jguru post) :
String[] cmd = { "/bin/sh", "-c", "/bin/ps -f | /bin/awk '{print $2,$3}' | /bin/grep
\"^$$\" | /bin/awk '{print $2}'" };
p = Runtime.getRuntime().exec(cmd);
Now that one is not really elegant, but kind of .. macho ! 5 processes in a row, with
pipes. Woaw.
To get serious again, it /is/ funny that Java does not provide this simple
function.
And somehow I have a feeling that there may be a catch somewhere when dealing with threads
under various platforms.
I prefer Konstantin's first suggestion.
Now the question is : if Tomcat writes it's PID to that file, where does Tomcat
get it from ?
thank you

The problem now occurs if a process has a lot of memory configured.
Like 25Gb on a 32Gb machine. In such a configuration the above command
fails with an OS'es out of memory, because fork
fails to create another process with THAT amount of memory:

Is there another method to obtain the process id from within the process?

Re: [OT] How to obtain the id of the current process
I found the following trick somewhere, maybe it works for you :
When starting your JVM, use a line like
java -Dpid=$$ program.java
and in the java program using the statement System.getProperty("pid");
If it works, it's cute, and certainly a lot less overhead.

I'm not sure I entirely understand the context, but if it's a Java 5+
process: ManagementFactory.getRuntimeMXBean().getName() will return
@.
Are you trying to determine the PID of a new process, or the current one?

[OT] How to obtain the id of the current process
Hi,
I have a ugly issue I'm sure many people on this list already solved.
For multiple purposes I need pid's of processes, to stop/start them or
ensure they are running. So far nothing spectacular.
To obtain the pid I have following util:
String[] cmd = { "/bin/bash", "-c", "echo $PPID" };
p = Runtime.getRuntime().exec(cmd);
and afterwards read the ppid from the output stream of my process. So
far - so good.
The problem now occurs if a process has a lot of memory configured.
Like 25Gb on a 32Gb machine. In such a configuration the above command
fails with an OS'es out of memory, because fork
fails to create another process with THAT amount of memory:
1598388 2010-11-17 02:54:47,061 ERROR net.anotheria.util.PidTools -
Could not determine PID: java.io.IOException: Cannot run program
"/bin/bash": java.io.IOException: error=12, Cannot allocate memory
Is there another method to obtain the process id from within the process?
regards
Leon

I will have to swallow my pride with this question. I bet this is a very easy issue, but for some reason I haven't found an answer. I moved my JARs from the ".../tomcat/shared/lib" directory to the "web-inf/lib" directory in the app itself, but it seems that the JARs there are not being discovered by Tomcat.

Maybe a web application/service isn't appropriate for this type of thing.

Generally multiple copies of the same class visible to an app but loaded by different class loaders is liable to cause issues. You can sometimes get away with it but often not.

Re: Change the class loading of tomcat 6.0.29 to child-first
Hi Mark Thanks for responding. Let's make an example. Suppose I have two libraries that implement the same functionality. The only differ for example for the version. Suppose my web app uses that kind of library. I have libV2.jar in the lib folder of the web app, and libV1.jar in the libs folder of tomcat so that libV1.jar is visible for all web applications. Now suppose that my web app only works with libV2.jar. I understand from your response that the class loader loads "offers" to my web app the libV2.jar so everything should work! right? But in my real situation if i run my web app in a "clean tomcat" without the Mule libs loaded it works. When i run the web app in a tomcat installation that loads those Mule libraries the web app does not work anymore. So waht is not working?

The above isn't going to work because Tomcat provides webapp isolation
in the JNDI space.
You should look into the documentation for Tomcat's JMX beans: I'm sure
there is a way to use those to create on-the-fly DataSources (really
DataSourceFactories I think) using the mbeans that Tomcat exposes.
Running under a SecurityManager may complicate that effort.

Instead, you see the class that implements that interface. N.B.: the HttpSession documentation says that IllegalStateException will be thrown when calling getAttributeNames on an invalidated session.

Change the class loading of tomcat 6.0.29 to child-first
Hi I'm running tomcat 6.0.29 on windows vista. I'have deployed a web application under webapps folder. This web application comes with some jar libraries. Unfortunately these libraries conflicts with others libraries installed under tomcat. I deployed under tomcat Mule esb so I have a lot of libraries loaded by the common loader that belong to Mule esb. And these Mule libraries conflict with my web application libraries. So basically I would like to tell tomcat to first load for my web application his libraries (under WEB-INF/lib) and then if a resource is not found it should be searched in the global libraries.

I don't know about the "login session timeout" (or even if it is relevant in
this case),
but if the browser has to wait more than 3-4 minutes for a server response, the
browser
will time out on the connection and declare the server dead.
You may want to consider that part first.

Re: Request count increases drastically in tomcat 6.0.29
Hi. Again, I do not know LambdaProbe and I don't know precisely how it names things. But what I believe is this : > http-443 > Current thread count: 1149 Current threads busy: 1148 Max threads: 3000 Max > spare threads: 0 Min spare threads: 0 Max time (ms): 896953 Processing time > (ms): 166070125 *Request count: 148736* Error count: 527 Received: 687Kb > Sent: 143Mb The "Request count" which you see there is probably a cumulative count of all the requests that Tomcat has already processed (or received) so far, since the time it was started. If so, then it is normal that this number will always go up, and never go down. What is more striking here, are the threads counts : the above says that Tomcat currently has 1149 threads started, and that all of them are busy. To me it looks like either your server is too small for the load, or your application is too slow to respond. Even if you told Tomcat that it can start a maximum of 3000 threads, that does not mean that it will do so. It may not have enough memory available to do it. How much RAM does your server have, and how much of it is being used ? (for a quick check, use the Windows Task Manager). It may also be your back-end database system which is slow in responding, and keeping the threads busy. Anyway, as per the information above, there are no "idle threads". That explains why additional users would be rejected : your server is just too busy to answer them. You need a bigger boat. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Request count increases drastically in tomcat 6.0.29
Warnier, Herewith I given the details: http-443 Current thread count: 1149 Current threads busy: 1148 Max threads: 3000 Max spare threads: 0 Min spare threads: 0 Max time (ms): 896953 Processing time (ms): 166070125 *Request count: 148736* Error count: 527 Received: 687Kb Sent: 143Mb Tomcat Version: Tomcat 6.0.29 Java:1.6.0 64 bit version Os: Windows 2008 Enterprise edition 64 bit The problem is when the request count is less the users can able to login and submit the forms without delay.Meantime request time keeps increasing and they are not able to login into application and submission of forms also taking long time and finally page is expired.We set the session timeout as 30 min.Then we are forced to restart the tomcat to come to normal condition.We are using the Oracle database. Is it the normal for any application to keeps increasing the request count. Is there any way to recycle this request count in my tomcat application server? --rujin On 17 November 2010 17:41, André Warnier wrote: > Rujin, > > as it is phrased, your message is not very clear. > It is probably a question of language or terminology. > I don't know how LambdaProbe displays the information, but > > - a "request" is what the browser sends to Tomcat (like "GET /index.jsp") > - when Tomcat receives the request, it selects an idle thread to process > the request > - while processing the request, the thread is no longer idle, it is working > - the thread produces the response and sends it back to the client > - then the thread becomes idle again, ready to process another request > > So, an "idle request" seems to be a contradiction in terms. > Please explain better what you mean. > > And the list strips attachments, so sending screenshots does not help. > > > rujin raj wrote: > >> MArk, >> >> Its request count >> >> Screen shot attached. >> >> --rujin >> On 17/11/2010, Mark Thomas wrote: >> >>> On 17/11/2010 06:45, rujin raj wrote: >>> Hi, I am using an application in tomcat 6.0.29 and the java version is 1.6 64 bit.

RE: Placing JARs in "..../tomcat/shared/lib" causes leaks when stopping apps?
Hi Mikolaj and Mark, Thanks for your help. I do know about aliases, but for some reason a couple of years ago I decided to keep each domain in a different context. And that reason was.hummm..like.. you know what? Either I forgot what the reason was (maybe because I have barely slept last night cause my website crashed), or there was no valid reason! As soon as I finish moving my JARs from the shared directory to the web-inf/lib directory and everything is OK, I will review that.

Re: WEB Application need to upload a txt / csv file with 100K records
Hi, you can do this using some ajax: First upload the file then in the returning JSP you will have a ajax request that check the status of the process. You can check the validation process, then the actual database insert. The resource checked will return the message (and depending of the returned message you display 'under processing' or the error message or whatever you need.

Re: Request count increases drastically in tomcat 6.0.29
Rujin, as it is phrased, your message is not very clear. It is probably a question of language or terminology. I don't know how LambdaProbe displays the information, but - a "request" is what the browser sends to Tomcat (like "GET /index.jsp") - when Tomcat receives the request, it selects an idle thread to process the request - while processing the request, the thread is no longer idle, it is working - the thread produces the response and sends it back to the client - then the thread becomes idle again, ready to process another request So, an "idle request" seems to be a contradiction in terms. Please explain better what you mean. And the list strips attachments, so sending screenshots does not help. rujin raj wrote: MArk, Its request count Screen shot attached. --rujin On 17/11/2010, Mark Thomas wrote: On 17/11/2010 06:45, rujin raj wrote: Hi, I am using an application in tomcat 6.0.29 and the java version is 1.6 64 bit.

I originally did struggle with encoding so have probably gone over the top in
an attempt to fix the issues I was having. I will review my code following your
suggestions.
Many Thanks
Rob

When doing that I get the following message: That's nice. I don't see a question above but I assume that your post was trying to report what you believed was a problem with Tomcat. The root cause of the exception is in code from org.n52: > org.n52.wps.webadmin.ConfigUploadBean.compile(ConfigUploadBean.java:233) You need to talk to whoever wrote/provided that code.

Re: Usage of Tomcat SSL in client-side class
Thanks André, I have been checking Apache Http Commons API for connecting through HTTPS in my client-side classes and it seems that protocol is supported well. My doubt regarding if I had to do anything special in the client side was related to the certificate, I have a self generated certificate using JSSE keystore tool and I had read that those kind of certificates must be accepted explicitly by the client (the same that browsers do), therefore I was wondering how can I do that in my client to accept that automatically... 2010/11/16 André Warnier > Moley Harey wrote: > >> Hello folks, >> >> I have a set of web services installed in Tomcat 6.0.26 that I would like >> to >> access using HTTPs, I have following the instructions in Tomcat web side >> to >> set up JSSE support and now I can access the web services using SSH. >> >> My question is what do I have to do in my Java client-side classes to work >> with HTTPs requests from Tomcat?

Re: Usage of Tomcat SSL in client-side class
Thanks a lot Christopher, my web services are implemented using JAX WS API and I am connecting using REST, I was planning to use Apache Http Commons library for HTTPS as is the one I am using for simple HTTP connections... 2010/11/16 Christopher Schultz > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > Moley, > > On 11/16/2010 9:33 AM, Moley Harey wrote: > > My question is what do I have to do in my Java client-side classes to > work > > with HTTPS requests [to] Tomcat?
