AW: Load Balancing Concepts
mod_jk and mod_jk2 are currently the only connectors that supports activeliy load balancing. What's easy to achive is the following: - one apache/mod_jk as web server for static content and load balancer for dynamic requests. - Many Tomcat 4.0.4 instances to serve dynamic content In this szenario you don't need an external loadbalancer. As I understand it, mod_jk encodes the value of the jvmroute of the engine tag in server.xml in the session id and uses that to route incoming requests to the correct tomcat. So your scenario should be possible. (I've not tried it) What's currently not clear to me is, if it is possible to achive your goal with one AJPConnector in each tomcat instance for all apaches. (That's what I would try first, as in this case the configuration of the mod_jk is the same across all apaches) Otherwise you can try to use one AJPConnector for each apache instance and modify the mod_jk configuration for each apache instance accordingly.

The session id holds the information which route should be used. So there must be either a cookie with a session id or an url that contains the session id. If you don't use cookies you have to encode the url. So either if the form is generated by your servlet use response.encodeUrl() to create the action url or if the form is static html change that to a jsp file and use a scriptlet to create the ation url. There is !NO! other way. (Beside forcing the user to use cookies.

RE: Mapping directory
I'm afraid I don't have any expertise whatsoever concerning vq server, and don't have to trouble with loading dlls either (all my servers run under unix). But my guess would be that vq server somehow knows which dll it has already loaded and refrains from loading it again, whereas tomcat does not check for this. Maybe you can figure out a way to determine if the dll has already been loaded (or which dlls are present in the system) and make the loading dependent on the outcome of this check. It would be a good idea to make this thread-safe as well, i.e. to use some kind of locking mechanism. Alternatively you could place an object in application scope to indicate if the dll has already been loaded (by your servlet) if you do not get access to the information about which dlls are already present in the system and if you are sure that your servlet/application is the only one loading this particular dll. If you initialize this object with an form of application-initialization-servlet during startup, you could use it as a semaphore (synchronization object / monitor) as well. I'm not aware of any standard mechanism helping with such problems. Hope that helps.

url rewriting is mostly done by a module that intecepts incoming requests and changes it the before the request is forwarded to the application. The Application doesn't see the original request.

url rewriting is mostly done by a module that intecepts incoming requests and changes it the before the request is forwarded to the application. The Application doesn't see the original request.

The server tells the browser to look at a different location for a given url. NO. I know about redirection and do not want it. I have a servlet which is very general and takes a general input and generates different outputs. I want the servlet to send a url back to browser along with the output. This way, I need not bother the client with different URLs for the same servlet, this is anyway handled by the html form.

RE: what is url rewriting
I'd say make it work the other way around. If you want those URL's to be meaningful to the servlet (think search engines or referring to a specific call to your servlet), you'd have to do that anyway. So instead of trying to rewrite the URL in the addressbar, you make your servlet generate the URL's you want in your address bar and put those in the HREFs/ACTIONs on your form. Then (if neccesary, ) after the request you map the URL to your servlet parameters.

RE: Session and IP
Afaik tomcat uses either cookies or url-encoding to get the session-id from the users requesting a resource, which has nothing to do with the ip address. The only circumstances I could imagine therefore are two differente browsers having installed the same session-cookie (which is quite unlikely and would require the users to actively copy those cookie from one machine to the other) or (which is much more likely) two users using the same encoded urls. This might happen if one user sends another the complete(!) link containing the session id by copying it out of the address-field of his browser, e.g.: http://www.yourserver.com/yourcontext/someresource.jsp;jsessionid=C21CC5E4A5 890818B3E56426925E86F9 This would let the other user share the same session as long as it has not timed out. best regards Andreas Mohrig -Original Message- From: Roland Carlsson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 14, 2002 11:20 AM To: Tomcat Users List Subject: Session and IP Hi!

But the time that the error occur at is not the time that the server is unreacheable. (In the services window it is seemed as working properly.) What may the reason for this problem? --The following error --NT machine --High Load(In fact load is not so high) --Or what ??? Thanks in advance, Serdar By the way the error is that is in localhost_examples_log.2002-08-13.txt : !--StartFragment--2002-08-13 20:58:36 StandardWrapperValve[default]: Servlet.service() for servlet default threw exception java.net.SocketException: Connection aborted by peer: socket write error at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:83) at org.apache.catalina.connector.ResponseBase.flushBuffer(ResponseBase.java:674) at org.apache.catalina.connector.HttpResponseBase.flushBuffer(HttpResponseBase.java:764) at org.apache.catalina.connector.ResponseBase.write(ResponseBase.java:647) at org.apache.catalina.connector.ResponseStream.write(ResponseStream.java:312) at org.apache.catalina.connector.http.HttpResponseStream.write(HttpResponseStream.java:189) at org.apache.catalina.servlets.DefaultServlet.copyRange(DefaultServlet.java:1903) at org.apache.catalina.servlets.DefaultServlet.copy(DefaultServlet.java:1652) at org.apache.catalina.servlets.DefaultServlet.serveResource(DefaultServlet.java:1197) at org.apache.catalina.servlets.DefaultServlet.doGet(DefaultServlet.java:519) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:190) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2347) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:468) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:174) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1027) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1125) at java.lang.Thread.run(Thread.java:484)
Re: Session and IP
Thanks for your answer. We are not using url-encoding, only cookies. Is it possible that a proxy can catch the page and fool the cookie system? We have not set any commands to proxys but the default that tomcat uses?

The only circumstances I could imagine therefore are two differente browsers having installed the same session-cookie (which is quite unlikely and would require the users to actively copy those cookie from one machine to the other) or (which is much more likely) two users using the same encoded urls. This might happen if one user sends another the complete(!) link containing the session id by copying it out of the address-field of his browser, e.g.: http://www.yourserver.com/yourcontext/someresource.jsp;jsessionid=C21CC5E4A5 890818B3E56426925E86F9 This would let the other user share the same session as long as it has not timed out. best regards Andreas Mohrig -Original Message- From: Roland Carlsson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 14, 2002 11:20 AM To: Tomcat Users List Subject: Session and IP Hi!

Re: forward to TOP-Frame
Hello Harry
You can't solve this with forward.
You need to do this client side with
either javascript ...
Here is a example of a javascript function.
Must run on the client side.
script language=javascript
!--
function logout() {
thePage = http://www.thewebsite.com;
top.location.href=thePage;
}
// --
/script

I have a similar but different problem. Running 4.0.3 on solaris 8 standalone with jdk 1.4 Occasionally, tomcat dies with no error message in any log file. It is as if someone has kill -9'ed the jvm.

Is this a game? You are trying to manipulate client side functionality without using the only client side programming feature (javascript) you have. Trying to develop any system with a browser front end without using javascript is a futile exercise.

RE: forward to TOP-Frame
I'm afraid tomcat itself can't help you with this at all, since you really have to convince the client browser to use the top frame to display your page. Once the browser has requested your page to display within a subframe, your page doesn't even know it is to be displayed within this subframe. You would have to send back a page that instructs the browser to reaload another (or the same) page in the top frame. Without JavaScript I would imagine this to be quite difficult. If this is _really_ important to you there may be another way, though. You may be able to emulate your frame-structure by composing your jsp-pages dynamically via jsp:include page=somepage/ and/or %@ include file=somefile%. I admit this would be a painful course of action if you have already designed your application to use frames, but then you could just send back a page missing alle the included parts, which will make it top. greetings Andreas Mohrig -Original Message- From: Harry Knörrer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 14, 2002 11:49 AM To: 'Tomcat Users List' Subject: AW: forward to TOP-Frame And javascript isn't allowed -Ursprüngliche Nachricht- Von: Harry Knörrer [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 14.

Re: Session and IP
Thanks for your answer. We have now put a header with nocache. One of the users that have reported the error of getting someone else data says that it works like it should so it seems like if the problem was in a proxy. I would like to ask for tomcat as default to uses nocache since that is the behavior at least I assume that a dynamic webserver to have. But I'll guess that there are arguments to not to do that. But to me it seems more logically to tell when to allow caching then when not to since the reason to use dynamic webservers are that the pages changes. Thanks again all who have helped!

AW: Session and IP
- I don't think that 'no cache' is a usefull default for most applications, as in most applications the pages that contain personalized data are the minority. (Beside thhe problem mostly happens together with forms with method=post as in this case the url doesn't change) - Yes, I would like an option where the behaviour can be defined globally for . To do this on your own you could write a filter that sets the headers before calling doChain(). - To be very shure that no caching happens in dialogs we use sequence numbers that we append as parameters to the url. This way the url changes with every request and is never cached at all. -Ursprüngliche Nachricht- Von: Roland Carlsson [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 14.

Hi, I have taken Andrews advise and upgraded Tomcat. I am now using version 4.1.8, however I am still getting the same problem.

RE: fixed classes
Hi, In general it's better to re-compile, re-pack jars, re-deploy jars, restart app. It's clean, quick and safe, especially if you have ant targets for all of this ;) As a temporary fix, you can put the fixed classes themselves, unpacked, in the /WEB-INF/classes directory of your application.

RE: How to keep track of sessions
Hi, So my first question is, why? If you could describe the motivation / requirements / goals for your need to keep track of all the sessions, perhaps someone could suggest an alternative approach. If tomcat is restarted then the sessions are persisted fine. However my vector of sessions is lost so I have no record of sessions that were created during a previous tomcat run. Any idea how I could find or keep the list of previously created sessions? Sessions are not meant to be persisted across server restarts. Perhaps you are only interested in specific attributes of the sessions? In that case, the Singleton pattern comes to mind to be used as follows: - Have an object, MySessionInfoHolder, that holds the stuff you need about the session, for example some attributes. You probably do *not* want to keep the session ID. - Have a singleton, MySessionInfoManager, that keeps a set (no duplicates) of these MySessionInfoManager objects. - Your session listener (either a Session or a SessionAttribute listener, or both) would extract the proper info from a Jakarta session object and store it in the manager. - On context shutdown, persist the stuff in MySessionInfoManager using castor (or any of the other similar packages) or your own serialization / XML / JDBC / whatever mechanism. - On context startup, recall the stuff from XML / the database / wherever into the manager. Would that approach work for your needs?

AW: How to keep track of sessions
You can implement a ContextListener that persists your Vector when the Context is shutdown. A quite dirty trick would be to store a reference to the Vector in each session and let tomcat do the work for you. -Ursprüngliche Nachricht- Von: Mark O'Driscoll [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 14.

August 2002 14:59 An: Tomcat Users List Betreff: RE: How to keep track of sessions Sessions are not meant to be persisted across server restarts. Obviously other people have other opinions about that. Session persistence is implemented in tomcat, if there would be no need that wouldn't exist :). - Have an object, MySessionInfoHolder, that holds the stuff you need about the session, for example some attributes. You probably do *not* want to keep the session ID. - Have a singleton, MySessionInfoManager, that keeps a set (no duplicates) of these MySessionInfoManager objects. - Your session listener (either a Session or a SessionAttribute listener, or both) would extract the proper info from a Jakarta session object and store it in the manager. That was not the problem, this part works. It's the vector of sessions that is missing as it is stored ouside the session. So your next paragraph is a possible solution. - On context shutdown, persist the stuff in MySessionInfoManager using castor (or any of the other similar packages) or your own serialization / XML / JDBC / whatever mechanism. - On context startup, recall the stuff from XML / the database / wherever into the manager. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: How to keep track of sessions
Howdy, Sessions are not meant to be persisted across server restarts. Obviously other people have other opinions about that.

I'm still unclear as to why one would want to save the session object itself, as opposed to only the parts of interest from it.

Re: How to keep track of sessions
I am using the sessions to keep track of who is logged on, for how long and what they have done. Obviously there are other non servlet ways to do this but as tomcat gives the opportunity to track sessions, I thought I'd use it. Session persistence highlights a 'hole' in the sessionListener interface. BTW: I'm surprised you think sessions should not be persisted. I think it's cool!

Re: Access Parameter
I totaly agree with Yoav comment. I just say that technicaly, it's exactly the same, and you should be aware of it. In fact, i have ever initiated a project where we finaly only use JSP for many reasons (principaly , the team was very new to Java/Internet/...), and make it work. BUT the result was poor, and some month later, we have to make it again because it was hard to make to code evoluate to fit the new needs. So, better use JSP for what it is good at : presentation and only presentation. In fact, since i know model 2 (also called MVC), i use it without limit. And refactoring or making my code evoluate is never a problem.

E.G. if you want to implement a session monitor.

Now he has a Vector of SessionInfo objects that have to be persisted if the server is shut down. The other option is to recreate the Vector on the SessionActivated event (don't nail me on the exact name I don't have that at hand) which is fired each time when a session is recreated from a persistent store.

Hi, I like this thread as a theoretical discussion, so let's pursue it a bit more ;) Depending on the kind of information you want to display it gets at sime point annoying to to copy everthing from the session to a store and to remove it from the store when the session ends. - More code = more possible error, less perfomance - More memory = less performance More code, yes. But I think the SessionInfo-type objects would be trivial. The manager would be very easy to write as well. As they are simple and completely under your control, you could make the processing and persistence operations very fast. Having tried that approach on long-running servers with many users and delayed session expiration (120min), leading to many SessionInfo objects that had to be persisted on context shutdown and restored on context startup, I can safely say that performance was not a problem for us. Even for thousands of SessionInfo object, the persistence operations were only a few seconds. And that's on a fairly small server box, JDK 1.2.2 without much tuning.

Now he has a Vector of SessionInfo I agree. You have to worry about persistence either way. However, persisting your own objects is typically a lot easier than persisting third party objects such as tomcat's session implementation. The part that I think makes his use-case very interesting and non-trivial is the requirement to record (and thus persist) the user's click-stream. I'm not sure off the top of my head how that fits into the SessionInfo object, except maybe as a list of URLs the user visited?

If my dirty hack (storing a reference to the vector in the session) works, it could be even simple and performant, if tomcat is clever enought to store just the references, the sessions are made persistent anyway) The part that I think makes his use-case very interesting and non-trivial is the requirement to record (and thus persist) the user's click-stream. I'm not sure off the top of my head how that fits into the SessionInfo object, except maybe as a list of URLs the user visited? We did not have this requirement in the aforementioned system, and so I can't speak to it... We do, but again we store the data in a database. (I don't like to hold that much information in memory, even in times of boards with 4 Gig memory, for me memory is a valuable resource that I don't like to waste.) -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

session timeout
How closely does Tomcat follow the servlet specification concerning web.xml? I added the following to my web.xml, but the session seems to timeout immediately (0 minutes). session-config session-timeout0/session-timeout /session-config However, the servlet 2.3 spec states: If the timeout is 0 or less, the container ensures the default behaviour of sessions is never to time out.

RE: Writing files from a class

RE: Quick Question
IMO, it seems like a bad idea to me to tie your bean
code to a servlet context unless you REALLY need to.
To me, a better way would be to put the file in a
directory under classes, and use the classloader of
the current thread to get to the file.
This way, you do not need servlet.jar to use your bean
if you every decide to use it outside of a servlet.
This is a very simple process. Here is an example:
private InputStream getFile(String name){
return Thread.
currentThread().
getContextClassLoader().
getResourceAsStream(name);
}
To read a properties file classes/myprops.properties
for instance, you just do this:
Properties p = new Properties();
p.load(getFile(myprops.properties));

RE: Writing files from a class
Hi, I see that the spec mentions private temporary directory - I need a permananent directory - by temporary I take it to mean that I can't count on the files sticking around. Is my understanding here flawed? Your understanding as far as a temporary directory is correct. If you need a permanent directory, you can: - Specify one as a parameter (resource-ref, init-param to a servlet, context-param etc.). - Use another storage medium, e.g. a database. Also, I'd like to be able to specify the name and location. I had seen the javax.servlet.ServletContext.log() methods, but they seem to offer no control over where the output is placed. I'd rather have a debug file per class than have all messages sent to a single file. I'm sorry, I don't have your original message in front of me. Are you using a logging solution e.g. log4j or commons-logging, or are you constricted to relying only on the ServletContext.log() methods? Log4j etc will let you configure the log files to whatever detail level you want, including path and separate log files per class. And finally, I have servlets that take data from a db and place it in a (text) file for the user to download - so once again a file creation issue where I need a general file i/o solution. Why can't you use the temporary directory for this? Unless you want to files to persist across server restarts, in which case you would either put them in a DB or tell your servlets what directory to use via the param methods mentioned above.

RE: Quick Question
Howdy,
good point, although if you need to write to the file,
getResourceAsStream
doesn't work. Is there something else along the same lines that will?
How's about:
URL destinationURL = ...getResource(...);
URLConnection destinationConnection = URL.openConnection();
destinationConnection.setDoOutput();
OutputStream outputStream = destinationConnection.getOutputStream();
...
You are not guaranteed this will always work across containers. I don't
think the spec says the container *has* to give you write permission to
URLs obtained this way.

Subject: RE: Quick Question
IMO, it seems like a bad idea to me to tie your bean
code to a servlet context unless you REALLY need to.
To me, a better way would be to put the file in a
directory under classes, and use the classloader of
the current thread to get to the file.
This way, you do not need servlet.jar to use your bean
if you every decide to use it outside of a servlet.
This is a very simple process. Here is an example:
private InputStream getFile(String name){
return Thread.
currentThread().
getContextClassLoader().
getResourceAsStream(name);
}
To read a properties file classes/myprops.properties
for instance, you just do this:
Properties p = new Properties();
p.load(getFile(myprops.properties));

It will work in a bean if you pass a reference
to the servlet context to it...
