Hi, Probably your browser is misconfigured. I don't think this is a tomcat issue. Check the file type associations in your browser and make sure that xls files are configured to be opened by msexcel.

Hi From: Antonio Fiol Bonnin [mailto:[EMAIL PROTECTED] Sent: 11 2004 . 11:39 Subject: Re: Datasource - OK in app context - Fails in Global context So, could someone summarize for me the different ways of creating a JDBC DataSource in Tomcat? I will start the summary, so that it's easier to correct/complete. Please fill in the gaps ;-) 1. Have the DataSource defined in your application's context. That way, if you have two apps, you have to copy the datasource definition from one to the other. Two connection pools will be created. If the database schema is different for each your of you applications you will end up using this setup anyway, so just go for that. 3. Have the DataSource defined in GlobalNamingResources. If you have two apps, you need to ResourceLink in both contexts. ... connection pool(s) will be created. This setup suit the case, when your applications all use the same database schema (means can access their database objects trough the same authentication/db user). Ofcourse only 1 pool will be created, so you'll have to scale the pool parameters for all the applications that use it.

RE: Encoding issues
I used to have similar problems with windows-1251 cyrylic codeapge and I solved it by
creating a siple filter, mapped to all request that explicitly sets the encoding of
the request before any1 else gets the request:
request.setCharacterEncoding(windows-1251);
I think this happens because Internet Explorer does not set the appropriate encoding
headers on HTTP level of the protocol and tomcat just assumes it is ISO8859-1 (leading
to garbage ofcourse)
Here is the full source of the filter:
package bg.cbm.servlet.filter;
import javax.servlet.*;
import java.io.IOException;
/**
* Creator: paltankov
* Date: 2003-10-30
* Time: 10:03:49
*/
public class LocaleHelperFilter implements Filter
{
private String defaultRequestEncoding = null;
public void init (FilterConfig filterConfig) {
defaultRequestEncoding =
filterConfig.getInitParameter(defaultRequestEncoding);
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
if (null == request.getCharacterEncoding())
request.setCharacterEncoding(defaultRequestEncoding);
chain.doFilter(request, response);
}
public void destroy() {}
}
Here is the mapping entry for web.xml of the application that uses it:
filter
filter-namelocaleHelper/filter-name
filter-classbg.cbm.servlet.filter.LocaleHelperFilter/filter-class

If so, sorry about being lazy. You seem to be hitting maxProcessors. If you do, no more threads are created, and connections start getting into SYN_RECV state, simply because Tomcat is not accept()ing them, exactly as you told it to do. So, either reduce your concurrency level for the tests, or increase maxProcessors. Actually, I don't think I'm hitting maxProcessors - usually when that happens, you only get an error message about no more threads being available in the pool. Here, the issue is that Java is unable to create a new native thread and therefore throws an OutOfMemoryError. So the problem is that even after the tests are complete and there are no active connections at all, it's no longer possible to connect. I think perhaps the OutOfMemoryError causes whatever thread is accept()ing new http connections to die. - Frode - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

How would Tomcat setup datasources? If I define a connection pool with 16 connections, will it be sread over the two servers, or will *each* get 16 connections. If they are spread, how is it done? Tomcat uses DBCP, which uses the Pool package which I guess have a singleton that manages the connections ... but on which server is the pool (singleton) then actually active?

RE: Threaded servlets okay in a compliant container?
David, you can have wget/Scheduled task on Win box -Original Message- From: David Wall [mailto:[EMAIL PROTECTED] Sent: 05 2004 . 20:54 To: Tomcat Users List Subject: Re: Threaded servlets okay in a compliant container? The use of a cron job that does a WGET on a URL that triggers the background processing sounds nice, but what's the process that triggers that on a Windows box that doesn't have cron? A huge power of our application is that it's written in Java and we can run it easily on Windows or Linux or Solaris. Linux and Solaris could allow a cron job, but I'm not a Windows person so I don't know how I'd do the same there. Also, if a process needs to be run every minute, or perhaps even every 5 to 15 seconds (like for processing a work queue), cron would be overkill because it would launch a new process, that process would have to construct the simple URL and the POST it to the system. Also, if someone else also did POSTs to that same URL, they'd also trigger the background processing though it wouldn't be on schedule per se. Using cron doesn't sound that much better than just writing a batch C/Java program that does this in a loop so that a process doesn't have to be started each time (though you then have the issue of what to do if the batch program terminates unexpectedly). The key for me is to have a very simple to deploy and manage application, and keeping Tomcat and a database running should be the minimum in our environment, though we probably will also have an Apache web server handling the SSL and static content like javascripts, images, URL rewriting, allowing for easy port 80/443 port listening without having to run as root, and allowing other types of backend apps run, like Perl/CGI or whatever. By far the easiest way to deal with work queues is to allow one thread to insert a transaction into a queue and then notify() the other waiting threads that work has been inserted. But that means that the work queue thread is a background thread and thus has issues with being truly compliant now and in the future. By far the easiest way to deal with background tasks is to simply launch a thread that waits() for a certain amount of time and then does work when that times out. Clearly, the cron type solution solves the thread issues, but at the expense of creating another program that needs to be configured and must run and must be checked if it's not running, and causes overhead each time it's launched.

RE: strange error messages in tomcat log and mod_jk2 log
My production server setup is Apache/1.3.19 (built on HP-UX)mod_ssl/mod_jk/tomcat 4.1.29 on a separate machine I have a moderate loads of 5-10 hits per second and no really big responses (no more than 300k) What I know so far is that this is caused by an attempt by the coyote connector to write in a already closed by the mod_jk socked. The hints I have so far: 1. some proxy servers in the middle might explicitly close lenghty collections 2. lotso ppl blame users pressing stop button in browser!? 3. I follwed some forum thread somewhere (cant remember now) where the guys had observed as a weird bahaviour of Windows IE. They had narrowed the log entry appearances to a hit to a page where the request was submited like this: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit() They were saying that the IE evaluates the onclick and submits the form, at the same time requests the blah/blah.html document, and THEN decides that the blah/blah.html document is not needed and just closes the socket. The guys also were saying that such a behaviour was not observed while tested with Mozzila and Opera browsers. They have been able to avoid it just by making the onclick event handler return false: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit(); return false Though, I have not tested it myself. -Original Message- From: Chris Joelly [mailto:[EMAIL PROTECTED] Sent: 15 2003 . 10:31 To: Tomcat Users List Subject: Re: strange error messages in tomcat log and mod_jk2 log Hi! thanx for your reply. hm. it's a very strange thing. some questions: are you running your application under heavy load? are the responses very big in size? do you use the apache2/mod_jk2/tomcat4 config on a windows nt4 box? does a dialogbox appear on the server with an error message stateing that the apache.exe caused an internal error, and after pressing Ok the apache2 server continues to run? maybe we can find some similarities. we have no idea what direction to look for, and the problem is very critical because a very big application is crashing every few minutes, so a production environment couldn't be setup... :-(( thx, Chris Am Fri, Dec 12, 2003 at 01:46:13PM +0200, Altankov Peter meinte: Hi!

forward(whatever, req, res);

Thanks for your help everyone . after some number of hours of work yesterday, I
managed to get everything changed over, and I'm NOT using the SingleThreadModel. I
inherited part of the code, and wrote most of the rest a couple of perl scripts
was able to help significantly.
Long and the short, was we were trying to get away with an OOP design, in which all of
our servlets derived from a single class (which in turn, implements HttpServlet), so
that our forward(), logging, and erroring methods could be easily implemented. In
doing so, you were all correct, we were over-writing our own variables.
On Wednesday I upgraded to the latest DBCP and Commons Pool, as well as the latest
JDBC driver for our vendor, reducing the number of those errors from an enormous 760
to 220. Today, thus far, we've had a total of 10 errors, only two of which were
related to that same problem, and probably are from me missing something in the code.
Thanks for your help in this mess

As a rule of thumb, do not let your req and res leave local scope
(do not store them anywhere [attribute, static attribute, other
object, ...]).
If you need help with the refactoring and I can access your code, I

Sorry, but I think your solution is not completely thread safe, because you do not
declare doGet synchronized. If you did that, it would be thread safe. But what is the
point then? Declare the servlet as implements SingleThreadModel, and you are done!
Obviously, you will not avoid other global or out of scope variables concurrency
problems with that.

Altankov Peter wrote:
If you go for the SingleThreadModel, try this to workaround your
problem:
public class TestServlet extends HttpServlet implements SingleThreadModel {

However, this interface does not prevent synchronization problems that
result from servlets accessing shared resources such as static class
variables or classes outside the scope of the servlet and moreover its
depricated.(http://jakarta.apache.org/tomcat/tomcat-5.0-doc/servletapi/
javax/servlet/SingleThreadModel.html)
In general avoid any global variables in the scope of the servlet class
definition unless you know what you are doing. Use method variables
instead. If you decide to go for the real problem solution, either
declare the req and res objects in the, lets say, doGet method and
pass them to the forward method, or keep their declaration in the
servlet class but mark the forward method as syncronized (causing
threads to enter it one by one).
Here are your hnt snipplets:
// the workaround
public class TestServlet extends HttpServlet {
private HttpServletRequest req;
private HttpServletResponse res;
[...]
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
[.]
forward(whatever);
}
protected synchronized void forward(String s) {
[.. Here is where you refer the global req and res objects ..]
[.. but its safe, since the method is marked as synchronized ..]
}
}
-- Or --
// some real solution
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
HttpServletRequest req;
HttpServletResponse res;
[]
forward(whatever, req, res);

My guess:
req and res are attributes of the Servlet, like in:

So you are calling forward(s) for a request once req and res have
been overwritten by another request.
Hmm... Im a bit lost here... could anyone perhaps be so kind and post a
code snipplet of how a thread safe use of a Servlet's request and
response attribute could look like? I have not been working with
Servlets for too long and I worried I might run into the same problem.

RE: mapping different JKMounts to same Tomcat context
Why dont you try the Apache's mod_alias directive: IfModule mod_alias.c Alias /xyz/ /path/to/abc /IfModule Since you have only 1 instance of tomcat and one instance of your webapp - this should do. -Original Message- From: Vijay Kandy [mailto:[EMAIL PROTECTED] Sent: 10 2003 . 18:52 To: 'Tomcat Users List' Subject: RE: mapping different JKMounts to same Tomcat context Thank you but the doc doesnt describe mapping to same context. If I have one worker per Tomcat instance, they work fine e.g: JKMount /abc/* WORKER1 JKMount /xyz/* WORKER2 where WORKER1 and WORKER2 are two different instances - this setup works fine.

RE: response.reset() and forward() ... problematic? DBCP related?

If you really cannot follow any of the above, there is still one
solution:
- Make sure your servlet implements SingleThreadModel. This will

no concurrent requests will occur.
Hope that helps.

Either that or you can just declare your method syncrnized:
protected synchronized void forward(String s) {
Which ofcourse will become a bottleneck of you application during loads.

RE: response.reset() and forward() ... problematic? DBCP related?
If you go for the SingleThreadModel, try this to workaround your problem:
public class TestServlet extends HttpServlet implements SingleThreadModel {
...
}
However, this interface does not prevent synchronization problems that result from
servlets accessing shared resources such as static class variables or classes outside
the scope of the servlet and moreover its
depricated.(http://jakarta.apache.org/tomcat/tomcat-5.0-doc/servletapi/javax/servlet/SingleThreadModel.html)
In general avoid any global variables in the scope of the servlet class definition
unless you know what you are doing. Use method variables instead.
If you decide to go for the real problem solution, either declare the req and res
objects in the, lets say, doGet method and pass them to the forward method, or keep
their declaration in the servlet class but mark the forward method as syncronized
(causing threads to enter it one by one).
Here are your hnt snipplets:
// the workaround
public class TestServlet extends HttpServlet {
private HttpServletRequest req;
private HttpServletResponse res;
[...]
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
[.]
forward(whatever);
}
protected synchronized void forward(String s) {
[.. Here is where you refer the global req and res objects ..]
[.. but its safe, since the method is marked as synchronized ..]
}
}
-- Or --
// some real solution
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
HttpServletRequest req;
HttpServletResponse res;
[]
forward(whatever, req, res);
}
protected void forward(String s, HttpServletRequest req, HttpServletResponse
res) {
[...]
}
}
I hope this helps.

Hi!
Antonio Fiol Bonnn wrote:
My guess:
req and res are attributes of the Servlet, like in:
public class TestServlet extends HttpServlet {
private HttpServletRequest req;
private HttpServletResponse res;
[...]
}
So you are calling forward(s) for a request once req and res have
been
overwritten by another request.
Hmm... Im a bit lost here... could anyone perhaps be so kind and post
a code snipplet of how a thread safe use of a Servlet's request and
response attribute could look like? I have not been working with
Servlets for too long and I worried I might run into the same problem.
Thanks in advance

RE: How to configure the default application in apache to point to tomcat??
The reason for 404 is that your application context is mapped in tomcat container under /myapp. Try this: JkMount /* your_worker_definition In apache httpd.conf, and: Context debug=0 docBase=/absolute/path/to/myapp - (or relative to CATALINA_HOME ofcorse) path= - this tells comcat that requests for / should be mapped to myapp I hope this hints help. -Original Message- From: Natarajan Arun [mailto:[EMAIL PROTECTED] Sent: 09 2003 . 00:03 To: [EMAIL PROTECTED] Subject: How to configure the default application in apache to point to tomcat?? Hi, I have integrated tomcat and apache. Now when I type http://localhost/myapp i get the page from the tomcat myapp application. However now, I want http://localhost to point to this application, since this is my default application. What configuration would I have to change ?? I tried using + Redirect / http://localhost/myapp in the apache httpd.conf but that + did not work. + Changing the alias in mod_jk.conf to / instead of /myapp also did not help. It lists the directory but then invoking any pages results in a file not found because it is probably looking in apcahe's document root. Thanks for any help.

Tomcat 4.1.24 and mod_jk
Hi, I am migrating to tomcat 4.1.24 and mod_jk on apache 1.3.26 configuration Unfortunately when i deploy my production webapp im getting constant lines in the catalina.out log file [INFO] ChannelSocket - -server has been restarted or reset this connection This INFO line is actually loged 3 and more times per request (js, img, css includes in HTML?). When I google it all I get is some postings about apache restarting its childs in order to avoid memory leeks. Obviously its not the case. Do u guys have any clue? Thanks in advance.
