U e...sure you could do that but you should ask yourself is this
the right thing to do? If the sample code you provided is similar to what
you're trying to implement I would recommend that you right your own
Runnable object and control it's lifetime using a ServeltContextListener
object. Or at least define the Runnable object as a private inner class of
the Servlet so you're not exposing a public method that isn't intended to be
called from outside the servlet. Just my 2 cents...

RE: How to set JVM memory size?
It's important to realize that this is setting the size of the Java heap within the JVM (which sounds like what you're looking for) and not the actual size of the JVM itself. Also note that you're not always going to get the best performance out of your app by using a large heap size because while it decreases the frequency of GC's the time each GC takes is going to increase (more to collect). So, and I know I'm not the first to say this, play around with the different settings until you find the one that suits your app. Jeremy -Original Message- From: Brandon Cruz [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 05, 2002 10:27 AM To: Tomcat Users List Subject: RE: How to set JVM memory size?

RE: how many linux processes should tomcat create???
Java threads under Linux show up as individual processes when you do a top or anything similar. The number of threads (Linux processes) that Tomcat creates will of course depend on the application you're deploying, i.e. if your app starts up a lot of threads for whatever reason you're going to see those show up as additional processes. I don't know the exact number off the top of my head but I would estimate that Tomcat itself starts 30 threads, of course this number also depends on the number of request processors you specify in your server.xml. In my experience any app that has 525 threads running needs to be looked at immediately. Having one or more open database connections is okay if you're pooling the connections in some way. If the number of physical connections to your DB is constantly increasing without bound then perhaps you have another problem to fix. Using netstat is should be easy to determine what's going on there.

RE: Socket GURU'S PLEASE HELP ON OBSCURE PROBLEM
Looks like you're trying to implement a small webserver but you're not
obeying the HTTP spec. You need to read the entire request in from the
client before responding and you should send the appropriate response
header, e.g. HTTP/1.1 200 OK, or your results will be unpredictable.
The reason you see it hang is because it's waiting for a response from
your server, it finally times out (Connection reset by peer) and closes
the connection. I would suggest using HTTP 1.0 on the server side to
avoid dealing with keep-alives sent by 1.1 clients. For more
information on the HTTP spec check out RFC 2616. Good luck on your
homework.

Subject: Socket GURU'S PLEASE HELP ON OBSCURE PROBLEM
The project that I'm working on is actually much larger and more
complex, but I've thrown together this class that illustrates my
problem. I'm basically starting a socket server on port 80 and then
connecting with a web browser. The strange thing is that the
connection
never terminates and I can't identify where it's hung up.
The code is as follows:
import java.io.*;
import java.net.*;
import java.util.*;
public class Lab9 {
ServerSocket ss;
Socket tempSocket;
BufferedReader instream;
PrintWriter outstream;
Socket connection;
public Lab9(){
try{
System.out.println(Server Started);
ss=new ServerSocket(80);
tempSocket=ss.accept();
instream=new BufferedReader(new
InputStreamReader(tempSocket.getInputStream()));
outstream= new PrintWriter(tempSocket.getOutputStream(),true);
ss.close();
String tempString;
System.out.println(Starting to read from client.);
while((tempString=instream.readLine())!=null)
{
//tempString=instream.readLine();
System.out.print(got:);
outstream.print(got:);
System.out.println(tempString);
outstream.println(tempString);
}
System.out.println(Done with Input.);
tempSocket.close();
instream.close();
System.out.println(Server Closed.);
}
catch(IOException e){
System.out.println(Error: +e.getMessage());
}
}
public static void main(String[] args) {
Lab9 bob=new Lab9();
}
}
The strange thing is where the output is concverned. The browser just
hangs indefinitely and claims that it's downloading the page. But on
the console I'm getting the following:
Server Started
Starting to read from client.
got:GET / HTTP/1.1
got:Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,

got:User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)
got:Host: localhost
got:Connection: Keep-Alive
got:
Then it hangs. This is what's really bugging me. It never exits the
while loop and it never iterates the loop again. It just hangs until
I
close the browser window. Then it gives me this:
Error: Connection reset by peer: JVM_recv in socket input stream read
There's obviously something here I'm not understanding. If the
inputstream is not null, then in my mind it should continue with the
loop and keep printing got and the line of input. Yet, the
connection
stays alive and the loop stops iterating. Is this a behavior of the
BufferedReader, is it a behavior of the Socket? Is this something
unique to using browsers? If anyone has any insight, I would
appreciate
it. Thanks.

RE: Socket GURU'S PLEASE HELP ON OBSCURE PROBLEM [OFFTOPIC]
The condition in your while loop is incorrect.
BufferedReader.readLine() is only going to return null when the end of
the stream is reached, i.e. when the client closes the socket either
fully or partially. What you really need to test for as a condition for
the end of the input are two consecutive line terminators, either
\r\n\r\n or \n\n. Since the readLine method only reads up to \r\n or \n
you'll have to add in some additional logic to test for this condition.
Hope this helps you out and please try to post only tomcat related
questions to this list. Thanks.

Thanks Jeremy.
You're right in that I'm not correctly implementing HTTP, but I'm not
sure that's my problem. When I kill the lines that write to the
output
stream prematurely, I still never exit that loop. My program just
simply waits forever. In fact, the client never times out. I've left
it this was for hours with no timeout.
I've found some info in the forums on readLine() being a blocking
thread and I think that's my problem though I'm still having trouble
resolving the issue. When I issue a timeout, my program errs out one
the timeout is reached.
Does anyone know of any way to resolve a readLine() or a read()
blocking forever?

The jar file containing several class files are located in
tomcat_home/webapps/axis/WEB-INF/lib. This is the same directory as
where
the jar
files for ldap are located.

RE: War files and config info
Try setting a parameter in your web.xml to the value of an external location for your config file. Inside your init() method check this location first for the config file you want to load, if you find it load it and move on, else load the config file you distributed with your application. Hope this helps. Jeremy Joslin Software Engineer Spotlife Inc. -Original Message- From: Bryan P. Glennon [mailto:[EMAIL PROTECTED]] Sent: Monday, April 08, 2002 3:24 PM To: [EMAIL PROTECTED] Subject: War files and config info Hi - We have a web app that gets distributed in a war file to a tomcat 4.0x server. One of the things in the war file is a configuration file for the app. This is an XML file that we open as a resource (using getResourceAsStream()) in our main servlet init() method. So far, so good. But, we need a way to override this file so that we can make config changes without redistributing the entire application. If we don't use a war file, we can just put the override file (using the same name) in a directory that is earlier in the class path. But we would like to keep the war file, since it does make distribution a bit easier. Any ideas on how to make this work? FYI, the exact call we use to open the config file is InputStream in = this.getClass().getClassLoader().getResourceAsStream(configFile); TIA, Bryan -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
