Re: Pass parameter to the JVM at startup
Looking back I was starting Tomcat from inside Eclipse with the Sysdeo Tomcat Plugin which apparently doesn't use the tomcat startup scripts, i.e., it bypasses startup.sh so it never sees -server. When I started tomcat manually via the cli with startup.sh with the JAVA_OPTS in catalina.sh it did see the -server option and it does indeed show up on the cli too: Nevertheless you can also configure the start options (e.g. to adjust the memory usage) when using the Sysdeo plugin... There's a dialog for this in Eclipse/Sysdeo as the startup scripts aren't used, as you mentioned. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat 5 slow, it's in production, please help!
Yoo, Yes switch to jk2 is faster! set parameters in OPT_CATALINA with -server Xmx=? and Xms=? Sorry values depend on your available memory on the server, parameters could be different with your version, check or google for correct parameters, should improve performance... Another option could be your code, have a good look at it and try to optimize... Greetings O. On 5/6/05, Jeffrey [EMAIL PROTECTED] wrote: I use just mod_jk, not jk2 I believe.

To quote Mladen: You are probably using prefork mpm, so there is no way to control the number of connections to Tomcat in any way, trough mod_jk. You can limit it only by setting MaxClients in the httpd.conf to the maximum number desired. Because of pre-forking mechanism each child process will eventually establish a single connection to Tomcat, thus the number of connections will rise from StartServers to MaxClients. So there are two solutions for prefork. 1. Make maxThreads==MaxClients 2. Add connectionTimeout=2 to AJP connector.

Simple JavaBeans applications not working (newbie question)
Hi,
First off, let me apologise for the level of detail in
this message; if possible, I'd have made it shorter.
Anyway, I'm trying to learn J2EE; Tomcat seemed like a
good choice to learn the underlying technology, rather
than a particular JSP/Servlet container's deployment
tool. I can get 'plain' JSP pages working fine.
Unfortunately, I'm having major problems developing my
own Javabeans applications for Tomcat; they all fail
as shown below. The demos that come with Tomcat work
fine (although I can't get the demo at
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/appdev/sample
to work; However- that's another story)
I understand that I should simply be able to drop the
directory structure containing my program into
$CATALINA_HOME/webapps, restart Tomcat (I'm using
5.5.7) and have it work.
Its contents (root:root ownership, Tomcat running as
root) is:-
skeleton
skeleton/subapp
skeleton/subapp/skeleton.jsp
skeleton/WEB-INF
skeleton/WEB-INF/classes
skeleton/WEB-INF/lib
skeleton/WEB-INF/lib/subapp

skeleton/WEB-INF/lib/subapp/Beany.java
skeleton/WEB-INF/lib/subapp.jar
skeleton/WEB-INF/web.xml
Contents of files listed at end of message.
Here's what happens when I try to run it:-
(1) When I try to access
http://localhost:8080/skeleton/subapp/skeleton.jsp
with the setup as above, I get
HTTP Status 404 - Servlet

127421 over what period of time? Without a profile it is impossible to say if Tomcat can handle the load.

Re: How do I handle International Characters

Re: Tomcat 5 slow, it's in production, please help!
It seems that, at least in most cases, the main menu page after a login is loaded slow. After that other pages are loaded pretty quick. Does that mean once a connection is established, browser and server communication is ok. If that is the case, maybe I should look more at the connection timeout at the OS level (solaris 5.6) since I see a lot of TIME_WAIT at the machine using the 'netstat -n' command. --- Jeffrey [EMAIL PROTECTED] wrote: Please see the answer embedded below. --- Parsons Technical Services [EMAIL PROTECTED] wrote: 127421 over what period of time?

Re: Simple JavaBeans applications not working (newbie question)
Another thing I noticed that you have placed your bean as a jar in the WEB-INF/lib directory - while this works perfectly the practice is to put custom class files in the WEB-INF/classes directory as just .class files under their respective folders (as per package declaration).. IMO the lib folders should only contain jar files that represent generic functionality as opposed to customised project specific class files in the classes folder. regards, Anoop On 5/7/05, Anoop kumar V [EMAIL PROTECTED] wrote: Michael, Everything works perfectly fine in your jsp and bean except that the package mentioned in your bean (Beany.java) file seems incorrect: It is: ** BEANY.JAVA package subapp; It should be: ** BEANY.JAVA package subclass; Or else an alternative is to change the folder in which the bean is to subapp from subclass to match the package name...

ClassNotFoundException - common/lib works, shared/lib gets exception
So that I avoid already loaded classloader problems with jar's that front native library calls via JNI, I am following the pattern of putting the jars into shared/lib. However, I get a ClassNotFoundException. If I put this into CATALINA_HOME/common/lib, everything works fine. It's my impression, though, that one ought to put it into shared/lib. I've tried both CATALINA_HOME/shared/lib and CATALINA_BASE/shared/lib. This is on Tomcat 5.0.28.

Re: Tomcat 5 slow, it's in production, please help!
I think that would be the direction I would take. If you need more proof: Sniff the connection to the server to confirm the lack of available connections. So far it is pointing in that direction. Another test you might do is create a connection from a known IP, close the browser and monitor the connection status. If it is hanging open then start digging. I think you may also be experiencing an issue of clickatosis. It occurs when the client doesn't think the page is responding quick enough and since more is better after 10 or 20 clicks they decide to wait or give up. Mean while for each click they cause a request which can bog things down. Wrapping this with the held connections you can get a scenario as such: Client hits site. No or slow response. Clicks again. Or several times. Often closes browser and tries over. This creates a new connection request. Snowballs from there. Think about this, do you really get over a 100k users in six hours? Or even 100k page requests? That's a lot of traffic. If the client machines abandons the connection before the server, then establishes a new one, it compound the problem. Find a way to have the OS let Apache handle the connection timeout and get it down to a reasonable time. Since you are inheriting this, there may be a reason that the connection timeout is set so high. If the original creator of this wanted the user to be able to sit on a page for a long time without losing the session and connection thus causing the user to have to re-authenticate. But then there is a trade off. which you are experiencing right now. Get the time down until the complaint about having to re-login get too high or until the connection speed delay is acceptable.

I did get the slow reaction if I hit Tomcat directly at port 8080 to the same webapp. But the tomcat manager web pages seem show up fairly quick. I may be repeating something that was covered because I have not been reading this thread in detail. So sorry if already asked and answered.

confusion to DBCP
I'm using mysql + tomcat as server to run jsp pages. and there are JavaBeans too. I have read a lot on the web that using a connection pool is very good. I just wondering why I should configure DBCP in tomcat? i think if i write the database connection in jsp pages(not in beans) I need configure DBCP in tomcat. if in the page I just call some JavaBeans to connect to database, i just need write a connection pool class in java. is that true? thanks -- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: trouble with Font objects in Tomcat
Is there at least someone that could tell me where to find more
information about the option JAVA_OPTS=-Djava.awt.headless=true?
What exactly is its purpose? Thanks in advance.

Hello,

Tomcat 5.0.30 and I get the same error. I have set a Windows XP

the option to the Java tab of the Tomcat monitor under Java Options:.
What is the cause of this error? Is there some way that I can make it

Re: trouble with Font objects in Tomcat
Look at this link:
http://java.sun.com/j2se/1.4.2/docs/guide/awt/AWTChanges.html#headless
This option is being used when you are operating on a machine without
graphics support (usually in a server configuration). You will use the
option for example when you want to do some AWT/Swing operation on the
server side (image manipulation). You want to check and see if you have
graphics support on your server (on unix/linux run something like xcalc
on the server).
Based on your information, it is your class that has problem and has
nothing to do with graphics.
