I can easily reproduce this "zip file closed" issue in trunk with a
simple jar containing Tomcat's icon in META-INF/resources/favicon.ico
if I change configuration by removing JreMemoryLeakPreventionListener
from server.xml.
The first request to /favicon.ico hits the error.
It is a rare configuration and IMHO a broken one.
I think that running without JreMemoryLeakPreventionListener is wrong.
A place that I know that closes JARs is WebappClassLoader#closeJARs().
The closeJARs() is called after StandardContext has started up.
But WebappClassLoader and WARDirContext use different API to locate
and open the JAR file and I do not see how they can interfere with
each other.
I cannot reproduce the issue with the standard configuration.
Best regards,
Konstantin Kolinko

Chuck, Thank you for your response. Unfortunately, due to some company policies on supporting packages as supplied by Red Hat, I am stuck with 5.5.23 for now. I've read the docs and I am aware of the setting for maxParameterCount, which is not set at all in my Tomcat. What I don't know is if it will be honored. I read some posts where it was apparently ignored and the default used instead. Can you confirm that setting maxParameterCount in the connector attribute will override the default?

maxParameterCount with Tomcat 5.5.23
A recent RHEL patch supplied the following Tomcat packages which attempt to address a possible DoS attack as outlines at the link below: tomcat5-jasper-5.5.23-0jpp.31.el5_8 tomcat5-server-lib-5.5.23-0jpp.31.el5_8 tomcat5-servlet-2.4-api-5.5.23-0jpp.31.el5_8 tomcat5-jsp-2.0-api-5.5.23-0jpp.31.el5_8 tomcat5-admin-webapps-5.5.23-0jpp.31.el5_8 tomcat5-common-lib-5.5.23-0jpp.31.el5_8 tomcat5-webapps-5.5.23-0jpp.31.el5_8 tomcat5-5.5.23-0jpp.31.el5_8 http://rhn.redhat.com/errata/RHSA-2012-0474.html Since then I've encountered a problem with exceeding the maxParameterCount which seems to default at 512: May 4, 2012 2:30:27 PM org.apache.catalina.connector.Request parseParameters WARNING: Exception thrown whilst processing POSTed parameters java.lang.IllegalStateException: Parameter count exceeded allowed maximum: 512 at org.apache.tomcat.util.http.Parameters.addParam(Parameters.java:331) at org.apache.tomcat.util.http.Parameters.processParameters(Parameters.java:407) at org.apache.tomcat.util.http.Parameters.processParameters(Parameters.java:358) at org.apache.catalina.connector.Request.parseParameters(Request.java:2400) at org.apache.catalina.connector.Request.getParameterValues(Request.java:1063) at org.apache.catalina.connector.RequestFacade.getParameterValues(RequestFacade.java:394). I do not need it to be the old default of 1 and I don't think I want to set it to unlimited (-1) but I do need more than 512 for the application I am supporting. Does anyone know how to tweak the maxParameterCount in a standalone Tomcat listening on 8080, requests are sent via Apache listening on 80? This is not Tomcat as supplied with JBoss, so a fix such as that detailed at the link below I do not think will work: http://docs.redhat.com/docs/en-US/JBoss_Communications_Platform/5.1/html/5.1.3_Release_Notes/ar01s05.html Thanks in advance!
Multiple tomcat Instances on Same Server and One Apache Instance
Hi, I am in need of a little help. I have 2 tomcat instances running on the same machine and one apache instance running on a different machine. I configured jk_mod to access the 1st tomcat instance. Now, I have a second tomcat instance running on the same server as the 1st instance. I would like to access both tomcat instances via the one apache webserver instance. Because some requests are referenced by the same name, there is a conflict. On the tomcat server in server.xml, one instance is running on port 8009 and the 2nd instance (in another directory structure) is running on 7009. On the apache server in httpd.conf, I have the following: Listen 80 . . . LoadModule jk_module modules/mod_jk.so # JkWorkersFile conf/workers.properties JkMount /abc* instance1 JkMount /xyz* instance2 In workers.properties, I have the following: worker.list=instance1, instance2 # worker.instance1.port=8009 worker.instance1.host=server..com worker.instance1.type=ajp13 worker.instance1.lbfactor=1 worker.instance1.socket_keepalive=1 # worker.instance2.port=7009 worker.instance2.host=server..com worker.instance2.type=ajp13 worker.instance2.lbfactor=1 worker.instance2.socket_keepalive=1 When I call abc*, it goes to instance1; and when I call xyz*, it goes to instance2. However, both instances have apps that start with "tsa". How do I configure the apache webserver to service the "tsa" app for both tomcat instances? Thank you... ___ Regards,

RE: Slow downloads through mod_jk on Windows XP
Andy- On the receive side *if you have windows scaling enabled* you supposedly *can* enhance the receive window by setting these registry keys HKEY_LOCAL_MACHINE\System \CurrentControlSet\Services\Tcpip\Parameters\TCPWindowSize HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interface\TCPWindowSize registry values can be set to a maximum of 65,535 bytes (without window scaling) or 1,073,741,823 (with window scaling).

Re: Slow downloads through mod_jk on Windows XP

But I do see some neat numbers in case people care. I was following this tread and was hoping that someone will say: "Do not use workstation grade software for server applications" but no. XP (Win7 falls in the same category) has good network stack but focused on client applications. There is a good reason why MS charges extra $$ for server versions since they make sure your server application don't perform well on workstation software. I'm not sure what to make of the customer reports of the slow downs but at this point, I'm going to have to ask them to use something like ab.exe to do the downloads instead of Internet Explorer (most of them use IE to do it). Maybe there's some stupidity with IE. IE tries to open several concurrent connection at once (RFC says that number is max 3) I'm sure you can simulate that with 'ab -c 10 -k -n 1 ...' Anyways, I'm closing the book on this (with a bookmark just in case) but wanted to provide the numbers in case people were curious what I got. There is nothing wrong with tomcat, mod_jk or httpd. It's just your use case. Regards -- ^TM - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Starting up Tomcat in debug mode with tomcat6:run
The most simple is to use mvnDebug (no need to add vm options all is already set in mvnDebug script). 2012/5/11 Henrique Ordine : > Hi everybody, > > I understand that to start up tomcat in debug mode I need to add the > following JVM options : > > -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n > > I'm using the Maven tomcat6:run plugin though to start up my application on > Tomcat.

Starting up Tomcat in debug mode with tomcat6:run
Hi everybody, I understand that to start up tomcat in debug mode I need to add the following JVM options : -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n I'm using the Maven tomcat6:run plugin though to start up my application on Tomcat. Does anyone know how I can set those JVM options for this plugin? Thanks in advance. -- Henrique Ordine http://hordine.wordpress.com/
