RE: Memory usage
setting the bean to null just marks the object as ready to be collected calling System.gc() requests to the vm when you are ready, please do your stuff. But gc only occurs when nothing else is happening ... it is a LOW priority thread. So as long as you have requests, GC will probably not happen but, this is vm implementation dependant ... so maybe it will :) depends on the vendor. -Original Message- From: Jurrius, Mark [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 03, 2001 11:43 AM To: [EMAIL PROTECTED] Subject: RE: Memory usage Correct me if I'm wrong. If for instance I want a bean removed knowing that System.gc() does not happen immediately, would setting the bean equal to null force the bean to be removed from memory right away and not have to rely on the garbage collection to eventually take place?

The only way to be shure that this happens, is to explicitly run System.gc(). Even that's not sufficient: it just suggests to the VM that garbage-collecting might be a good idea right now. Any actual garbage collection would take place later, in another thread. And, even when it does happen, that doesn't mean all the memory will necessarily be released to the OS: the VM will hold on to some so that it won't need to go back to the OS on the next allocation. You might want to get a memory profiler (like JProbe) and see where the memory is going. At the very least, try doing something like, Runtime rt = Runtime.getRuntime(); System.err.println(Free=+rt.freeMemory()+, total=+rt.totalMemory()); often, to see how much memory is actually in use, and how much is just allocated from the OS. -- Bill K. -Original Message- From: Ralph Einfeldt [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 03, 2001 5:51 AM To: '[EMAIL PROTECTED]' Subject: AW: Memory usage That your finalize method is called, doesn't mean that the garbage collector has released your objects.

Mai 2001 14:34 An: [EMAIL PROTECTED] Betreff: Memory usage snip/ I have in trouble with the memory usage with Tomcat 3.21, WinNt 2000 and Jdk 1.3 of Sun. the problem is that any operation does not release the memory occuped; to control the memory usage I use the Task Manager; when Tomcat start, the memory used from the process Java is of 9608 K; when I request a Jsp page that has an error, like a variable not declared, the memory used is 11868K; if I wait for 1 ay also, this value does not change, so the memory used is not released, running a correct Jsp page, the memory used increase, and this is not released yet; I have written a log on the finalize method of my class, and this is called, so the garbage collector release all my object. This behavoir is normal? Probably changing the version of Tomcat this problem may be corrected. snip/
RE: ArrayList vs. Vector
which (in theory) makes ArrayList's cheaper ... if you dont need synchronized access to your structure, you should use with ArrayList. jb -Original Message- From: Nick Christopher [mailto:[EMAIL PROTECTED]] Sent: Monday, April 23, 2001 4:59 PM To: [EMAIL PROTECTED] Subject: Re: ArrayList vs. Vector Hunter Hillegas wrote: I use Vectors in some parts of my Web app and I'm thinking about using ArrayLists instead...

setting up logs
Is there a way to set up a log file to report what servlets/jsps have been accessed. I need the following information - what webapp and servlet/jsp - time of access - from where (ip address) Jasper.log is ok for jsp, if it reported from where but I still need to now about servlets. thanks in advance Jody Brownell Product Development Core Networks Inc.

RE: setting up logs
right now I have three logs ... servlet.log, jasper.log, tomcat.log. jasper.log is great for loggin when a JSP serves a request, tomcat.log doesn't really tell me anything and servlet.log is just as bare as tomcat.log. I have all verbosityLevel set to "INFORMATION", I dont really think I need debug info :) e.g Logger name="tc_log" path="logs/tomcat.log" verbosityLevel = "INFORMATION" / Logger name="servlet_log" path="logs/servlet.log" verbosityLevel="INFORMATION" / Logger name="JASPER_LOG" path="logs/jasper.log" verbosityLevel = "INFORMATION" / Out of curiousity, how would I combine both the jasper.log and servlet.log? Logger name="servlet_log" path="logs/action.log" verbosityLevel="INFORMATION" / Logger name="JASPER_LOG" path="logs/action.log" verbosityLevel = "INFORMATION" / would this work?

RE: setting up logs
I like that! Unfortunatly I am looking for a quick fix for now. I will definatly consider this at a later time, thanks, Jody -Original Message- From: Michael Wentzel [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 15, 2001 11:24 AM To: '[EMAIL PROTECTED]' Subject: RE: setting up logs Could you not have a logging servlet then? that logs all requests, then forwards the request to the appropriate servlet. I think you'd probably be better off implementing your own RequestInterceptor. Check out /src/org/apache/tomcat/core/RequestInterceptor. While this is can be Tomcat specific it a very logical place to put this mechanism IMHO.

Help please :)
Hello, I tried to post the following to the soap.apache list with no luck, You are my last hope :) When using tomcat(3.2.1) to serve soap requests everything works fine. When apache(1.3.17) is added to the picture I get the follwing stack dump. Is it possible that mod_jk.so is stripping whitespace. That is what it sounds like. When apache is removed from the picture, everything works as per usual.
