re: on adjusting incoming queue
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 - From what I understand there are two queues in Tomcat, and incoming queue and an execution queue. It appears tomcat is rejecting some clients when too many people try to hit my server at one time. During this time the cpu utilization was about 80%-95%, which probably exacerbated the problem. I hope I am understanding what the incoming queue is for, as, if the size of the queue is 10, and 12 clients try to hit the server at the same time, then 1 or 2 clients will get an error back from tomcat. If I adjust the size of the incoming queue so that it is larger than the current value of 10 might that cause problems with other parts of tomcat? I don't seem to hit the limit of 150 threads on the execution queue, but I did see it get to 109 threads in use at one point. Is there any way to monitor how many connections are rejected because the incoming queue is full? I am using Tomcat 5.5.9, on Solaris 9 with jdk1.5.

Re: Tomcat Tuning Memory leak
David Strupl wrote: I have already changed this ;-) Also added the fork attribute to true for jsp compile. It is not caused by the app - after the app starts and first 100 or so users connect the memory jumps up to approx 130 MB. But during the next 24 hours it eats more than 300 megs. From what I have seen from the profiler so far number of my objects is fairly decent. But there are more and more approx 100k (98320 chars) buffers created somewhere. I will post more precise info later after I a. upgrade to the latest and greatest JDK 1.4.2_03 b. create some HTML output of the heap Your JSP page shouldn't have any business logic in it, that should be in beans that your JSP page uses. You can test the beans in a profiler and see if there is any memory leaks. If you are using JDK1.4.1 then that will probably be your problem as there was a memory leak in the String class that was fixed in JDK1.4.2. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Classes cannot be found
Jeff Greenland wrote: Does anyone know a way around the serialization problem? If there's an easy solution, I would jump on moving all of our classes into a package immediately -- something we've been wanting to do for a few years. Thanks for the help everyone, hopefully someone has a deserialization solution as well! Write a standalone application that will go through the customer records, extract the information using the old classes, then repackage them in the new classes and reserialize them? That should work, then you can just move to the new, better, structure. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: java.lang.OutOfMemoryError
You may need to go modify Catalina.bat (I guess that is what it would be on Win2k), add a JAVA_OPT variable, such as JAVA_OPT=-mx512M. I don't remember if it is -mx or -mX though. This will set the highest heap size that the java application can use. You may want to set it to 2 or 3GB though instead. You may also want to use a profiler and see if you have a memory leak in your application.

RE: unit testing when application level scoping used
-Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Monday, December 22, 2003 10:03 AM To: Tomcat Users List Subject: RE: unit testing when application level scoping used Cactus works beautifully with regards to servlet context and general environment setup. Should I instantiate a bean with session scope that is expected to be present? Also, how do I handle the fact that I need to log in before I can test the parts I need to test? This whole set up is very difficult to unit test, and that is bothersome, as I am certain that this is a source of considerable errors in applications. Thank you for your response.

re: unit testing when application level scoping used
Hello, I am trying to write a unit test for an application I didn't write. There are classes in the classes directory I want to test directly. The problem is that the application uses application and session scoping for some of the classes, so they can reference the instance without having passed it into the instant I am trying to test. I hope this makes sense, I started to understand what was going on last night. How can I unit test a non-jsp page, non servlet page, when scoping is involved? Thank you for any help. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why JBoss (and Tomcat)?
Michael Coughlan wrote: I agree. Sorry to be so thick, everyone. I hope I am not too far off topic with this conversation thread, but I simply don't understand how JBoss differs from the J2EE SDK. There is a specification for J2EE, and then Sun makes an implementation of that specification, just as many other companies implement the spec. There are differences among the implementations, depending on what your needs are. JBoss for example also supports aspect oriented programming, if that will help your application out. Perhaps this will help you decide which application server to use. http://www.theserverside.com/reviews/matrix.jsp - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why JBoss (and Tomcat)?
Michael Coughlan wrote: It seems to me that I might want to blow away my Tomcat install and unpack JBoss (with Tomcat). You should look at what you will need, in terms of features, and what you can spend, and then decide. Sun's implementation also uses Tomcat as do at least some of the other implementations. There is no reason to develop a new application to compete with tomcat when it is so well done, so the differentiation is outside of tomcat. Jboss is a good choice, if it meets your requirements, but, all I have used is JBoss and Sun's implementation. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I believe the reference implementation is not meant for production, from Sun, but for $2k or $10k/cpu you can buy one that is. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: unit testing when application level scoping used
Shapira, Yoav wrote: You can use MockObjects for this type of thing, assuming that you mean the ServletContext and similar scopes. We are using a commercial application that is buggy. I am trying to test it to see if a new version is better or not than the current version, but I can't test the webapps because the class expects that some classes are already instantiated, as they are set in an application scope by a servlet or jsp page, and there are other classes set in a session scope by other jsp pages. When this is done, will cactus work, or will I need to write my own jsp page, instantiate the classes needed myself, then run the unit test, so that everything is set up for it? I have never thought of the difficulty of unit testing when using servlet contexts.

re: compiling tomcat-5.0.16 from source
Hello, I am curious how I compile all the components of tomcat from source code. I am having various problems, the only one that made sense was that I had to upgrade mail.jar. From the $HOME_DIR/jakarta-tomcat-5.0.16/src I should just be able to type 'ant' and have it compile, but it appears that the connector section isn't compiled and catalina isn't compiled. Thank you. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

re: integrating Tomcat5 with Apache2
Hello, I recently upgraded to tomcat5 and now have a problem with trying to do the integration. I used to use (under Tomcat4) in server.xml Listener className=org.apache.ajp.tomcat4.config.ApacheConfig ... / but now I can't find any ApacheConfig. I am trying to get tomcat to create automatically a file that apache will read in to know what directories are in the tomcat. At the moment they are not integrated, and it appears that the documentation for Tomcat5 is not exactly like Tomcat4 on this subject. Any help would be appreciated. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to monitor RAM Usage

I also can't find this information on the Apache site, after having looked for 1/2 hour. If you use top (on unix) or the taskmanager, on windows, you can see how large it gets. Most likely you will just need to add a java option to catalina.sh try JAVA_OPTS=-mx512m if you want it to grow to 512megs in size. Any thoughts/info would be greatly appreciates. Thanks.

RE: How to monitor RAM Usage
Thanks. Out of curiosity, what sort of RAM allocations would you typically do on a production UNIX machine? Obviously I don't want to use up all of my memory, but this and mySQL are my only two production apps. It depends on what your application does. Mine does a lot of graphs, and the data could be considerable, so I have it where it can be up to 400M. You could try 256M and see if that works for you. Your unit tests should help to see if that is enough. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
