Re: avoiding multiple form submission
1) How do you submit your forms ... a few years ago I had a guy who show my that issue, in fact he submitted the form oncheck on an input image ... 2a) There is a simple server side pattern two avoid double submit:(could not find the www reference). * jsp put a token in the session (scriplet, taglib). * submit action test the token and remove it from the session. so the second post can safely fail as the token is not found ! 2b) js code !?

Limit Num Requests
Hello, I'm running a j2EE with Apache front end and Tomcat at the back accessing a MySQL db. I have some heavy urls, can take around 2 seconds each call. While testing the site with JMeter if I put 25 users in a thread group and hit the above url concurrently I kill my tomcat instance. This means that someone could bring my site down with the above method? I'm looking for some way to stop this happening. Could be caused by by ajp13 connector? I'm not looking for a solution to cut down the time it takes to service each request, with caching for instance. Thanks in advance, Adam. -- View this message in context: http://www.nabble.com/Limit-Num-Requests-tf2858769.html#a7987047 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Limit Num Requests
From: adamle [mailto:[EMAIL PROTECTED] While testing the site with JMeter if I put 25 users in a thread group and hit the above url concurrently I kill my tomcat instance. What's the error? Do you run out of memory, for example? How much memory have you allocated to the JVM? I'm looking for some way to stop this happening. Cut down the number of worker threads in Tomcat to limit the number of requests that are processed concurrently? Note that this has the unpleasant side-effect of throttling Tomcat's request processing even for the lighter pages that don't cause problems. Could be caused by ajp13 connector? Much more likely to be an application issue - there are plenty of other people on this list who run Tomcat with significantly higher loads than that with no issues.

RE: Limit Num Requests
Thanks for the reply Peter. I am caching these pages after they are processed, but because of the nature of the application, they are many different kinds of these pages. Tomcat does not even throw an exception, I have allocated 128-356 mb memory. It just dies and does not response to requests. I am looking for a solution that for a certain url pattern only allows a certain number of requests to be serviced at the same time. This would solve my problem, while not affecting servicing lighter pages. Cheers, Adam.

Re: How to Run Servlet
no wonder, add the classpath to servlet, you need to ad the servlet-api.jar e.g : javac -cp d:/path/to/servlet-api.jar HelloServlet.java Athula, I suggest u startoff with an IDE, I recommend Netbeans for a beginner to servlet. download the Netbeans5.5 then new project, choose web project, choose the bundled tomcat as the server then new servlet, choose any name, or HelloWorld. Then you'll get a starter servlet and a mapping after that you can start running... and you can test using a browser. If the bundled tomcat port is 1980 then you tried hitting http://localhost:1980/context path/mapped servlet-name for example if my context path is /Dummy and the mapped-servlet-name is HelloWorld then I hit http://localhost:1980/Dummy/HelloWorld try it I always regard a servlet as a cgi java, if you want to do a complex programming, i recommend you start with java 1st then the servlet and jsp, you might wanna take a look at Spring Framework, Struts, WebWork or GWT On 12/20/06, athula bogoda [EMAIL PROTECTED] wrote: Here is the out put.

But for IIS, /luntbuild does not exist. How does it figure out that it is a Tomcat dir? Have you configured URI mapping ? I use jk1.2 (not jk2), I have a uriworkermap.properties file which saved from my former tomcat installtion. It seems that new version tomcat does not contained this file.

Hi there,
It is well noted by Google (and other search engines) that they do not like
session tracking info as part of the URL. This does include JSessionId, and
because Google visits your site as a cookieless user, every page indexed by
them includes JSessionId, this is bad for numerous reasons - but the main
reason is that Google may think you are cheating, as they are indexing the
same page multiple times and it adversely effects your ranking.
It is annoying as Tomcat deals with the URL according to standards, It seems
to be everything else which doesn't. To be more precise, it is the ';' in
the URL which servers such as Apache, and search engines and spiders like
Google don't like much at all. By all rights Google should ignore the
session id but it doesn't.
Anyway, how do I turn this cookie-less tracking off for Tomcat? I would
rather have better ranking (and not be banned) than have a minor percent of
customers not being able to use my site. Or is there another solution that I
have missed here?
Kind Regards,
Simon.

Hi Joe,
This is my commit(). I think you are missing the User Principle.
When you say request.getUserPrincipal(), that
token (1) I am putting in first comes back. The Principles you add
after that are the roles you want to test against.
This stuff drove me nuts when I was setting it up. Hope that does it for
you.

Re: Multi processor issue
BINGO :-) Please check the servlet spec 2.5, SRV 8.2 To use a request dispatcher, a servlet calls either the include method or forward method of the RequestDispatcher interface. The parameters to these methods can be either the request and response arguments that were passed in via the service method of the javax.servlet interface, or instances of subclasses of the request an response wrapper classes that were introduced for version 2.3 of the specification. In the latter case, the wrapper instances must wrap the request or response objects that the container passed into the service method. The Container Provider should ensure that the dispatch of the request to a target servlet occurs in the same thread of the same JVM as the original request. Please note that the last paragraph. I assume if the servlet container works properly, your method simply can't work. Can you remove Dispatcher caching and check whether the issue is gone? regards Leon On 12/20/06, Marziou, Gael [EMAIL PROTECTED] wrote: By looking at the code of ApplicationDispatcher, I would tend to think that the answer is no because of fields like wrapRequest and requestURI (there are other fields but they are unused) however the javadoc does not mention it.

Re: JSessionId and Google
Also, if you have been running your site with jsessionids for awhile then the spiders have your jsessionid urls on their link frontier. So the spiders will continue to crawl your site for jsession funky urls even once you've prevented your tomcat from generating them. Tomcat strips the jsession part of the url before you get to test them so this can be hassle. Try a apache mod_rewrite rule: IfModule mod_rewrite.c RewriteEngine On RewriteRule ^(.*)jsession(.*)$ - [R=404] /IfModule On Wednesday 06 December 2006 5:53 pm, Simon Pink wrote: Hi there, It is well noted by Google (and other search engines) that they do not like session tracking info as part of the URL.

RE: Need help with JK2 connector/workers2.properties
I tried to get it to work with JK1.2 but I got the same page not found error. There was no workers.properties and uriworkermap.properties files in Tomcat 5.5.20 so I had to make my own. This might be the problem.

I'm not sure the above is really pertinent to the issue, which I think can be boiled down to this: Should a RequestDispatcher object be treated as if it were in the scope of a Request or instead in the scope of a Servlet? The spec provides no definitive statement that I can find, but there are a couple of hints that a RequestDispatcher should be considered unique to each request. In particular: SRV.8.1.1 Query Strings in Request Dispatcher Paths: The ServletContext and ServletRequest methods that create RequestDispatcher objects using path information allow the optional attachment of query string information to the path. Parameters specified in the query string used to create the RequestDispatcher take precedence over other parameters of the same name passed to the included servlet. The parameters associated with a RequestDispatcher are scoped to apply only for the duration of the include or forward call. SRV.8.4.1 Query String: The request dispatching mechanism is responsible for aggregating query string parameters when forwarding or including requests. SRV.15.2.8 ServletContext, getRequestDispatcher(String): The resource can be dynamic or static. Based on the above, I think the app's reuse of RequestDispatcher objects is indeed erroneous. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I already compile the file and put both .java and .class file it to the C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\bo (bo is the file I put my develped files) after I browse the file using http://localhost:8080/bo/ It show all files in it. But when i click on the HelloWorld.class file it disply as a pop up dialog box to Open. How can I dispaly this servlet in the browser. Thanks.

I already compile the file and put both .java and .class file it to the C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\bo (bo is the file I put my develped files) You need to read the Servlet spec and become familiar with the proper structure of a webapp. In particular, your bo webapp should not go under webapps/ROOT, it should be in webapps/bo. Under the webapps/bo directory, you need a WEB-INF/web.xml, where you will specify your URI path to servlet class mappings. Take a look at the sample applications that come with Tomcat for examples, and get the Servlet spec from here: http://jcp.org/aboutJava/communityprocess/first/jsr053/index.html - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Servlet with POST Request
I see, you're thinking in Sockets
Sockets are usually :
1. open connection
2. give start byte
3. keep streaming the job byte
4. give the stop byte
The question is. How long is the number 3 ? how long between the 1st adduser
and the 2nd adduser ? if its very short then you can use put, if not... you
can consider writing a socket server or creating an async servlet, the logic
is
1. Hit the startjob servlet and get a trxid
2. Hit the job servlet with trxid and jobdescription as its parameter, this
servlet will write the jobs and its sequence to database
3. Hit the endjob servlet with trxid as its parameter, this servlet will
commit the whole process.
Make sense ?

I am creating a client - server application that will process lines like:
startjob
adduser
adduser
adduser
adduser
endjob
adduser can be an unlimited amount of times. I want to process the
lines as they come into the Servlet, that way a seperate process could
be doing something to complete each of the tasks, while I am in the
process of working on reading the lines.
I have written a Socket server of my own to do this before, I am now
trying to use Tomcat Servlet to do the same thing, because Tomcat
already some behind the scenes stuff already setup.
Does this make sense? Am I totally off my rocker? (My wife would
definately agree with that last bit.)

Why do you want to read POST by using reader ? I only use the stream

A pretty cursory test seems to indicate not, but I could just be
lucky

Have you tried this yet? request.getReader() would seem to cover
your situation, assuming this isn't binary data.
Hm, the reason I asked, is because of a test I ran. strLine is always
null.
Using the following code for processRequest:
response.setContentType(text/plain);
m_out = response.getWriter();
m_bufRead = request.getReader();
while (true) {
strLine = m_bufRead.readLine();
if (strLine != null) {
if (strLine.startsWith(login)) {
ProcessLogin();
} else if (strLine.startsWith(exit)) {
break;
}
} else {
try {
Thread.sleep(1000);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
}
}
m_bufRead = null;
m_out.close();
