RE: Virtual Host to Redirect
Why don't you just set the DNS so that all hosts resolve to the same machine, and then set the default virtual host to have the files you want in it? George Sexton MH Software, Inc. Home of Connect Daily Web Calendar Software http://www.mhsoftware.com/connectdaily.htm Voice: 303 438 9585 -Original Message- From: Boemio, Neil (GEI, FGI) [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 6:26 PM To: Tomcat Users List Subject: Virtual Host to Redirect I have a sever with 2 IPs. One of the IPs (say 1.2.3.4) is going to be used as a redirector to point all our domains to one main domain. Example: Typing in another.name.com will send the browser to my.main.com another.name.com/somepage.jsp will send the browser to my.main.com yetanother.name.com will send the browser to my.main.com This will be accomplished by having all our domains point to this one redirector IP in our DNS. I'm running Apache 2.0.47 and Tomcat 4.1.27 with JK2 as the connector. So in my Apache conf I have: VirtualHost 1.2.3.4 RewriteEngine On RewriteRule /.* http://my.main.com/ [R] /VirtualHost Now this works fine if I go to http://1.2.3.4/. It redirects to my.main.com just fine. My problem is that if I enter something like http://1.2.3.4/somepage.jsp, then it does not get redirected. Instead Tomcat serves it up. I believe this is happening because I have the following in my workers2.properties file under the Apache conf directory: # Map JSPs to the Web server uri space [uri:/*.jsp] worker=ajp13:localhost:8009 So it seems the connector is sending all JSPs to Tomcat and the Rewrite in the VirtualHost is never getting to do it's job. But of course, I need JSPs to go to Tomcat. Does anyone know how to get around this problem? Or perhaps there is a better way to accomplish what I'm trying to do? Thanks a bunch!

RE: Tomcat Settings and Performance
It's nice to see someone that I agree with on performance optimization. So many people take either a dogmatic, or a scattershot approach to optimization. The most important thing is to measure. This quote sums it up: When you can measure what you are speaking about and express it in numbers you know something about it, but when you cannot measure it, when you cannot express it in numbers, your knowledge is a meager and unsatisfactory kind. It may be the beginning of knowledge but you have scarcely in your thoughts advanced to a stage of science. - from the Popular Lectures and Addresses of Lord William Thomson Kelvin in 1891 - 1894. -Original Message- From: Christopher Schultz [mailto:[EMAIL PROTECTED] Sent: Friday, November 14, 2003 9:31 AM To: Tomcat Users List Subject: Re: Tomcat Settings and Performance Steve, Maybe this is common knowledge, but you know never to do this right? String x = a + b; You have to do something like this: StringBuffer b = new StringBuffer(); b.append(a); b.append(b); Using StringBuffer vastly improves performance. Ugh! This is like saying never use goto. In this example, you are completely wrong: String x = a + b; compiles to: load x, ab which is a lot better than: getclass StringBuffer dup dup new load a invoke append load b invoke append store x The Java compiler will take constant string expressions that are concatenated and perform the concatenation for you. The code is smaller. However, if you are doing a lot of string (dynamic) processing, than using StringBuffer is to your advantage, because lots of string operations are converted (again, by the compiler) into uses of the StringBuffer class. There's also nothing wrong with doing this: String path = SOME_STOCK_PATH + argv[0]; Because if you want a String object that looks like some/stock/path/mypath, and not a StringBuffer containing those characters, then why would you write this: StringBuffer sb = new StringBuffer(); sb.append(SOME_STOCK_PATH); sb.append(argv[0]); String whatIreallyWanted = sb.toString(); This is exactly what the compiler will do with the code. You can't improve the speed, because you are just doing compiler work. What have you gained? Loss of readability, which I think is a poor tradeoff for no benefit. There is one was to make it better. Do this: StringBuffer sb = new StringBuffer(SOME_STOCK_PATH).append(argv[0]); or even StringBuffer sb = new StringBuffer(SOME_STOCK_PATH.length() + argv[0].length()).append(SOME_STOCK_PATH).append(argv[0]); At least then you'll have a somewhat appropriately sized array, and you'll avoid the re-allocation of arrays required to handle the string sizes. Over the versions of the JVM, StringBuffer and String performance have been improved; the implementors know that String objects get created all the time and are used heavily in the standard library and pretty much everywhere else. Bottom line: don't resort to performance improvements at the expense of readability of your code. I consider this to be a classic case of premature optimization. -chris - 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]
RE: RequestDispatcher.include() on 5.0.14
I Emailed Remy off list. Essentially, the problem appears intermittent
and may be hardware or JVM related (but I don't think so...). Here is
the text of the last message I sent to him:
You are right. I wrote a test case, and it worked.
I then went back and re-tested my original application. This time it
worked.
Today, I ran into another problem where I was getting a
ClassCastException retrieving an attribute from a session. When I run it
under 4.1.29, it works perfectly. FWIW, Tomcat 5.0.14 was not doing this
last night. There are many other places throughout the application where
this attribute is retrieved from the session, but this is the only one
failing. Just for grins, I made a small code change and re-compiled.
Unsurpisingly the issue went away
I just tried both issues on a different machine running 5.0.14 w/ JDK
1.4.1_01 under Windows and all aspects are working correctly.
The machine where I have been having issues is running SUSE 9.0
professional with JDK 1.4.2-b28. I tried upgrading the JVM on the SUSE
machine to 1.4.2_02-b03 and still had the same issues. This machine has
been running Win2K reliably for several years. To be safe, I ran
MemTest86 on it, and it reported no issues.
At this point I have conflicting data. On the one hand, the app works on
one machine with 5.0.14. On another machine, it doesn't work with
5.0.14, but works well with 4.1.29.
At this point I have to say I believe there is something (or many
things) wrong with 5.0.14. The problem appears intermittently, and is
difficult to trigger with many different symptoms.

RE: RequestDispatcher.include() on 5.0.14
OK, I have figured this out.
The issue is that I was deploying the contexts using the Admin
application. When I deployed the Root contexts, I specified the path as
/.
I was able to replicate the error on another machine by doing this.
Specifically, I could replicate the ClassCastException. After
replicating the error on the second machine, if I changed the context
XML file path to , then the application worked correctly.
I guess what confused me was that the context basically worked. If it
hadn't worked at all, I would have figured out the path was a problem.
Remy,
What is the correct thing to do here?

Admin Application
I created a new virtual host using the Admin Application, and attempted to deploy the Manager application using the interface. Initial attempts gave this message: java.lang.ClassNotFoundException: org.apache.catalina.manager.HTMLManagerServlet org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLo ader.java:891) org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLo ader.java:756) org.apache.catalina.authenticator.AuthenticatorBase.invoke(Authenticator Base.java:594) After some fooling around, I found that the issue was that the context need the privileged attribute set to true. I looked, but I don't understand how to use the Admin application to set this attribute for a context. More to the point, is it possible for the manager application to work across multiple virtual hosts? It seems like quite a waste to have to configure the manager application for each virtual host? I guess another, perhaps better question is why does the Admin application not have controls to stop, start, and re-load contexts? George Sexton MH Software, Inc.

More Admin Application: Service Reloading Question
I am evaluating Tomcat 5.0.14 for use in a ASP Hosting environment. As part of this environment I would need to routinely create (or destroy) virtual hosts. One major showstopper seems to be that if I create a virtual host and click on the Commit Changes, then the service reloads, including all of the virtual hosts, and their associated contexts. Is there some setting I don't see that can affect this restarting behavior? Without the capability to create virtual hosts on the fly, I will have to schedule routine re-starts of the servlet engine.

IBM JRE 1.4.1 dumping core on login with http/1.0 browsers
I'm having problems with the IBM 1.4.1 jvm dumping core every few days under fairly light use with tomcat 4.1.27. I'm looking for general advice (though specific advice would be even better).

Re: IBM JRE 1.4.1 dumping core on login with http/1.0 browsers
Daniel, et al, thanks for the info. I have put this in my tomcat script, but I thought it was a kitchen-sink approach, since I only thought this only applied to RH 9.0 with the NPTL thread library. But now the water is muddier since I found this http://speakeasy.rpmfind.net/linux/RPM/redhat/updates/8.0/i586/kernel-smp-2.4.20-20.8.i586.html which mentions NPTL in reference to the (8.0) kernel I have. Anyone know if this applies to RH 8.0 with the latest smp kernel? I noticed you also mentioned putting it in the apache startup script. Is this important, since apache does not (I thought) share threads with the jvm? At 03:56 PM 10/23/2003, you wrote: Search for Java IBM LD_ASSUME_KERNEL in google. That may be your problem. Then set an environment variable in your apache and tomcat startup scripts: export LD_ASSUME_KERNEL=2.2.5 I hope that helps. It seems to have solved my crashes.

Problem with Tomcat SSL Port
I am having a problem with embedded Tomcat 4.1.18. The problem is that after some unspecified period of time Tomcat is continually opening http processor threads that are then stuck in the CLOSE_WAIT state. I am seeing this intermittently in Windows, HP-UX and Linux. I am using the coyoteconnector to create both an http connector and ssl connector. The http connector continues to work, but the SSL connector stops working. This bug is supposed to be fixed in 4.1.24, but I question that based on the following bugs described in these links: http://www.mail-archive.com/[EMAIL PROTECTED]/msg103402.htm l http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23311 Here are links to the related bug that was fixed: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=14994 From looking at the stack trace it appears that the problem may be in the code org.apache.tomcat.util.threads.threadpool. When I looked at the source for that code, there are two methods that use notify instead of notifyall(), which is a very dangerous practice and can easily cause the behavior I am seeing. It appears as though changing these two lines to use notifyall() instead of notify() could fix the problem, however I have not tested this out. I wanted to verify that this code was changed in the latest version of threadpool in the tomcat-util.jar file, but in the latest releases of Tomcat I can't find the tomcat-util.jar file or the source for ThreadPool. However, you need that file to build http11processor.java, so it must be somewhere. Does anyone know where to find the latest versions of tomcat-util.jar for tomcat 4.1.27? Also if anyone knows if this code has definitely been fixed that would be helpful as well. Thank you, George

Subject: HTML quoting
What's the standard way of quoting text for inclusion in a web page in
Java? Ie. I need a method to convert the string
Jeb said, Hell damnation! Is 5 4?
to
Jeb said, quot;Hell amp; damnation! Is 5 gt; 4?quot;
(I think: I've never been entirely sure what the right way to handle
quotes is.) That is, I want the standard Java equivalent of Python's
cgi.escape(), or Perl's CGI::escapeHTML().
To my utter amazement, I cannot find any indication that such a method
even exists in the standard Java library! (I tried Google'ing and
poking through the JDK 1.4 docs.)
So I went looking in the source for Tomcat 4.1.27 -- surely the HTML
version of the manager app must quote at least the webapp's display
name, since it comes from a user-supplied file and therefore might
contain funny characters. Surprisingly, the manager just lets funny
characters through without touching them. Eg. if you put
display-namefoo amp; bar webapp/display-name
then amp; is translated back to by some part of the XML-parsing
chain, and is emitted as in the manager HTML page. Most browsers
can deal with minor violations like this, but it's still technically
incorrect. Just for fun I tried this:
display-namemy
lt;scriptgt;alert(foo);lt;/scriptgt;/display-name
...and it works! The manager emits this HTML:
td class=row-leftsmallmy scriptalert(foo);/script
webapp/small/td
and my browser pops up a JavaScript window while rendering the manager
page. Cool! I doubt this is a security hole -- not many people can
edit web.xml! -- but surely it at least counts as a rendering bug. ;-)
So: can someone tell me what the standard way of quoting text for
inclusion in a web page generated by a Java web application is?
Thanks!

RE: invalid direct reference..--problem with solution..
I would like to implement a fix to this. I think having users bookmark the
login page is a very likely frequent problem.
But..
What happens if you implement this solution and the user has disallowed
cookies? Don't you get an ugly loop?
If the referer header was set, you could use that, but it does not appear
to be. Anyone have a bright idea?

Subject: Possible workaround for invalid direct reference to
login page
Java Authentication with tomcat relies on realms. If you
access a page
protected by that realm you get directed to the login page.
However, it is possible to go directly to the login page (
this can happen
when users bookmark the login page inadvertantly ).
This happens in two scenarios:
1) The user is already logged in.
2) The user is not logged in.
If you authenticate yourself once you have gone directly to the login
page, you get a invalid direct reference error. Fair
enough, the login
page is trying to redirect to itself. Now, I tried to
workaround this by
checking if the session is null, and if it is, redirecting to some
protected page, eg. protected/index.jsp. No luck. It seems
that a session
is implicitly created, and a new session id gets created.
So I've tried a cookie strategy:
%
if ( request.getCookies()==null ) {
response.sendRedirect(//jsp/protected/index.jsp);
}
if ( request.getRemoteUser()!=null )
{
response.sendRedirect(/x/jsp/protected/index.jsp);
}
%
i.e, we wont have a cookie if we've gone directly to the
login page. But
we will have if we've tried to access a protected page and
then we've been
forwarded to a login page, tomcat will give us a cookie.
Now if we're already logged in ( which we check with
getRemoteUser() ,
then we just forward to user to an index page.
This seems o.k. However my index page actually includes my
login page! I'm
planning to get around this with some logic that only
includes the login
page excerpt if we are not logged in..

Subject: invalid direct reference to form login page...
Hi all,
I've set up Tomcat (4.1.24) to do form based authentication.
Everything
works great, except I've had to deal with a lot of users that
type in the
url I've given them, get redirected to the login page, and
bookmark the
login page before logging in. Later, when they use the
bookmark, they get
sent to the login page, but get a Invalid direct reference
to form login
page... message once they log in.
I understand why this happens, but don't know what to do
about it. Is there
a way to specify a default page to go to when the login page
is requested
directly?
Thanks,
Brian Kuhn

how to autogenerate mod_jk.conf w/ Tomcat 5?
Can anyone help with configuring Tomcat 5.x (as comes with Java WSDP) to integrate with Apache 2? As a longtime user of Tomcat 3.x, I've come to appreciate the auto-generation of mod_jk.conf, a feature that seems to be missing in Tomcat 5. Or is there a better way to have my webapps automatically integrated with Apache? I found a few guides on the web that discuss how to add Listeners to server.xml, but the class (org.apache.ajp.tomcat4.config.ApacheConfig) does not seem to exist in Tomcat 5. I plowed through the .jar files hoping to find its modern analog, but to no avail.

Cheers, George - Original Message - From: Dean Fantham [EMAIL PROTECTED] To: Syed Nayyer Kamran [EMAIL PROTECTED] Cc: Tomcat Users List [EMAIL PROTECTED] Sent: Tuesday, June 10, 2003 3:29 AM Subject: Re: Urgent : Can we restrict access to a directory in tomcat There is no guaranteed way to stop someone directly access a gif image via a browser url, because this is how an image is accessed by the browser itself anyways. The browser just makes a HTTP get request to the web-server (in this case tomcat) requesting the URL of the image to be included in the web page. i.e. in a standard jsp/servlet response to a web request the image request is embedded in a img src=.../somedir/some-img.gif. This is going to cause a browser request directory to the directory containing the image, which can also be duplicated in the browser. The only potential method that can catch most (but not all) of these would be to create a separate image handling jsp/servlet, say imageHandler. When imageHanlder servlet recieves an image request it can check the http-referrer header and ensure that the referrer is the url of the page to which the images are supposed to load, i.e. is the page containing the images in /servlet/somepage then the http-referrer that imageHandler see should be able to checked that it is /servlet/somepage. Someone can circumvent this control by the Internet, but just manually setting this header themselves (via a program or the like) and then having access directly to the images You would then have to update all image referrences on the somepage servelt/jsp however to something like img src=/servlet/imagehandler?gif=somerefernce.

Unfortunately, if I add another Logger className=... declaration to

RE: Can't get Servlet Inputstream
The Servlet is listening for requests. When a request is made it sends a response.
The request is one of the parameters to the servlet, and you can tell that it has
content in it, but you can not get the content from the request with getInputStream
and I don't know why that is. Maybe I am missing something, but it should work.

I´m don´t understand why you need the InputStream from a Servlet
once servlets just write text to client´s browser. And besides, what are you
expecting to get from InputStream? To get FORM parameters and cookies and
related things from client side you must call resquest methods.

Assunto: RE: Can't get Servlet Inputstream
As far as the exception it depends on whether I try to do a getInputSteam
or getReader call on the request. If I use getReader, I get an exception
that says getInputSteam has already been called. If I change the call to
getInputStream I always get nothing back.
Thank you,

Howdy,
Very interesting. Interesting enough that I want to try to reproduce it
myself, but my local tomcat instance is running a 12-hour long
performance/stress profile.
So in the meantime, let me ask this:
- Which version of tomcat?
- Which JDK?
- Does getReader() work?
- Are any exceptions thrown by the getInputStream request?
- Are there any relevant exceptions in the tomcat logs?
- Have you verified your tomcat installation is good by running the

Subject: Can't get Servlet Inputstream
I am converting a servlet from using Jigsaw's Servlet methods to
Tomcat's

returns null. This calls works fine in Jigsaw receiving the same XML
data,
but returns null in Tomcat. Any help would be appreciated. Below is
a
simple example of the code that is failing:
public void doPost(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException
{

System.out.println(Content lenght = +request.getContentLength()); //
this line works
ServletInputStream in = request.getInputStream();
// this returns null, why?

}
BTW - I can read the request header and content length fine from the
request, just can't get the inputstream.

RE: Can't get Servlet Inputstream
From the exception thrown it appears as though getinputstream has already been
called. I am using the embedded tomcat class to start Tomcat 4.1.18.
I have to go now, but I can provide the exact exception thrown later.

How do you get auto-deploy to work right using embedded Tomcat
I have used a variation of the embedded tomcat example code from the onjava site (http://www.onjava.com/pub/a/onjava/2002/04/03/tomcat.html?page=1). The problem I am having is that I can not get the WAR file auto-deploy mechanism to work the way that it does in stand-alone Tomcat. The functionality that I am trying to get is to have Tomcat 4.1.12 unpack the WAR files in the webapps directory so that the URL to access the WAR file contents is the name of the WAR file. For example, say that I have a WAR file named CoolStuff.WAR. This WAR file contains tag libraries that are in JAR files, jsp pages and html pages. It contains a file called index.html that is in the root directory of the WAR file. In standalone Tomcat when you place this WAR file in the webapps directory, to access the index.html file you would load the following URL: http://localhost:8080/CoolStuff/ , but using the embedded Tomcat you run into problems. If you use it as is, the WAR file in the webapps directory does not expanded, so you have to do one of three things (as far as I can tell so far): 1. Change the example so that these lines: // Create the ROOT context Context context = embedded.createContext(, getPath() + /webapps/ROOT); host.addChild(context); read: // Create the ROOT context - not really anymore Context context = embedded.createContext(, getPath() + /webapps); host.addChild(context); 2. Add a HostConfig LifeCycleListener: HostConfig hConfig= new HostConfig(); ... host.addLifecycleListener(hConfig); 3. Upgrade to Tomcat 4.1.18 and use the StandardHost APIs to deployWebApps: // Create a default virtual host host = (StandardHost) embedded.createHost(localhost, tempPath.toString()); host.setUnpackWARs(true); host.setAutoDeploy(true); None of these solutions provide the same functionality that stand-alone Tomcat does, so I am still searching for a solution that does. The problem with the first solution is that the ROOT context can not be added with , which means that you have type out ROOT in the URL. Which is different than stand-alone Tomcat. The problem with the second solution is that you get errors when the WAR file unpacks, because the JAR files won't unpack properly. It seems to be related to this issue: http://www.mail-archive.com/tomcat-dev@jakarta.apache.org/msg37181.html that does not appear to be fixed yet. The problem with the second solution is that although the WAR files get deployed, the WAR file name is not used in the URL, so in the example stated above instead of loading the index.html file from http://localhost:8080/CoolStuff/ it would load from http://localhost:8080/ which is not the way stand-alone tomcat works. It seems to me like there should be a simple solution to this, but I have not found one yet (besides not using embedded Tomcat). Any help would be appreciated.

RE: Simultaneous request from same IP
Let us apply Occam's Razor here. You probably haven't heard of it so I will
repeat it here and show the application to your situation. Quite simply, it
says that when you have two competing theories to explain something, the
simplest theory is usually the correct one.
So, let's apply this:
Theory 1 proposed by you: Tomcat is horribly broken, and unthread safe. It
has major problems processing more than one simultaneous request to a
servlet and no one but you has noticed this. Hundreds or thousands of
developers and applications have not heretofore brought this to light, but
you have.
Theory 2 (proposed by several people on the list): Your application is not
thread safe, and is broken.
Occam's Razor says that your program is broken, and you need to fix it.

TrafficCop is thread safe because add() is synchronized. Regardless if
trafficcop is thread safe or not the values that I get from
HttpServletRequest should not be the same. If I were to take TrafficCop
out of the servlet, I would get the same results in my servlet. I guess
what I am saying is that TrafficCop should have nothing to do with the

But the same trafficCop instance is being used at the same time for 2
differnt requests.
The trafficCop object has a method called add() which (seems to) acts
on instance variables inside of the trafficCop object. This makes the
trafficCop object not thread safe.

As others have said, you need to re-design your app. Personally, I would initiate the computation in a background thread and mail the results to the user as a PDF document. Further, I would use a queue design so that only one computation is running at a time. What will your app do if the user hits back, and keeps re-submitting?

Changing Keystore location when embedding Tomcat
I am taking advantage of the Embedded tomcat class in Tomcat 4.12 to embed tomcat in an application. I am trying to determine how to change the location of the default keystore. This is normally done by modifying the server.xml file, but since the embedded code does not use the server.xml file I need to find a programmatic way to change the location. The following is an example of the code to create the connector: Connector connector = embedded.createConnector(null, 443, true); Since the embedded code ignores the server.xml file and since the API for creating the connector does not allow you to change the keystore location, I looked at the connector class. It appears that the connector class does not allow you to change the location for the keystore file either, but I could be missing something. Is it possible to change the keystore location, without modifying the core Tomcat classes?

RE: Java returns bunk date!?
If you don't need the time portion, I once wrote a replacement for the calendar that handles just dates. Unlike all of the bizarre manipulations required by a calendar, with mine you can just call object.add(7) to add 7 days to a date. It uses an internal Julian date field. Checking for elapsed number of days is a straight integer subtraction. It pretty closely mimics the date capabilities of xBase variants. Personally, I never use calendars. They are just too obtuse and error prone. If you are interested you can view the Javadocs at: http://www.mhsoftware.com/resources/jar/doc/ The class name is SaneDate.

You could use SMB to mount the files from the Windows machine to the Linux machine. If you need high performance, this will have a hit. Alternatively, you could write a shell script that will sync the files on Windows over to the Linux machine using ftp. ncftpget is pretty nice for an ftp program that could keep them in synch. If you have to have immediate updates, then SMB is the way to go.

We don't use it in that way. We have a load balancer in front of our nodes, which has a standby balancer, if the first one goes down. If we want to get your requested behavior, we had to configure this on our load balancer, not on the nodes. This balancer knows nothing about apache, tomcat and mod_jk. So I don't know how to manage it with mod_jk. I don't know how your config should work. Because if N1 routes to all other nodes and N1 goes down, how should your client know, that he had to connect to N2? You need some logic in front of your cluster, that the clients see your cluster as one big server. If you want something like standby or hot standby you must implement this in the front logic, not on the nodes. And I don't know if this is possible with jk1. Why do you limit the balancing to N1? Most of the work is done in your servlets. The balancing is not so hard, that it will bring your node down. If all nodes do balancing its no problem, if one node goes down.

You need to take an off-line approach where the servlet places a job request into a job queue, and another application (or perhaps a servicing thread inside tomcat) services the request and mails it to the user.

At times one or more end-user's request may take several minutes possibly up to an hour to complete.I am attempting to plan for a worst case scenario that has all end-users making requests that take up to an hour to complete. From my understanding of Tomcat it is possible to configure how many requests can be processed at one time and how many can be on a queue waiting. In my scenario, it is possible that all requests processing could be waiting on data from the mainframe, yet Tomcat and the Web server itself would have cycles to process requests queued waiting. I'm wondering whether there is a way with Tomcat/Servlets that I might set up my own worker queue and thread pool to process requests; keep the connection with the end user (client) active and free up tomcat requests for additional processing?

I have Tomcat 4.x as Servlet Container and I have seen that sometimes the following strange thing happens When Tomcat doesn't receive requests for a period of time (that can take minutes or hours) it suspends itself and I must restart the service manually because Tomcat doesn't answer to the users' requests any more. In fact when this happens and then a user tries to connect to Tomcat he waits for an answer forever without success until the connection is closed by the Web Browser because it is timed out. Is there some setting in Tomcat to avois this? Has someone already had such problem? If yes, how did he solve it? I hope someone can help me Thanks in advance.

RE: Losing session in Internet Explorer 5x
There is a bug in IE dealing with re-directs and SSL. I forget how it works but it went something like this: Login page invalidates session. User enters user ID and password. Login page re-directs to target page IE Generates spurious additional request to login page which again invalidates the session. If you have pages that invalidate the session, you might want to take a look at them. Also, if you have a network protocol analyzer like Ethereal on Linux watching the packet flow can help you sort it out. George Sexton MH Software, Inc.

Possible bug with isSecure()/getScheme() methods in tomcat 4.1
Hi, I am having some problems with the servlet engine when connected to apache. When making a https request through the apache webserver the HttpRequest.isSecure() method is returning false and the HttpRequest.getScheme() method is returning 'http'. It seems like this information was lost when the connector passed the request to the servlet engine. I should note that the HttpRequest.getServerPort() does return the correct port. Having looked through the archived messages it sounds like there was a similar problem when using ajp12. However, I am fairly certain that I using the ajp13 protocol. I am able to work around this problem since I can use the getServerPort() method correctly, but I would be interested to know if this is a bug or if I have misconfigured something.

Step 1: Register a session context listener. Step 2: When each session starts, store an Integer in a Hashtable. The key would be the user name. The Integer value is the number of currently active sessions. Step 3: In the session destroy, decrement the Integer count, and if it is 0, remove it from the Hashtable.

RE: default charset in contentType?
Too bad! Setting the charset explicity in the Jasper compiled servlet breaks IE for image/svg+xml content. It seems that Microsoft does not properly recognize the contentType header so that for example running the resulting servlet thus: http://localhost:8080/foo/servlet/test?dummy=.svg will work but running it properly thus: http://localhost:8080/foo/servlet/test will not work?

RE: Using Non-Servlet Timers (Was - I need to run a servlet periodically)
Register a context listener and free the timer in it. -Original Message- From: gautam [mailto:[EMAIL PROTECTED]] Sent: 09 October, 2002 9:53 PM To: Tomcat Users List Subject: Using Non-Servlet Timers (Was - I need to run a servlet periodically) Hello, We are using java.util.Timer objects to periodically run through a few object caches and get rid of stale items. Everything works fine. However, I can no longer stop Tomcat using the Catalina.bat stop command. I suspect that the Timer objects are still alive and are the cause of the problem. Any ideas on how to fix this ? The objects we schedule via the timers are not Servlets. They are plain vanilla Java classes.

The servlet can get parameters from the web.xml file (like how often to execute) and pass that to your class that controls the timer. The servlet can pass your class the connection pool info and other needed session info.

Make your client to run periodically and it will cause the servlet to run. We can suggest you a solution if you let us know what exactly you want your servlet to do.

RE: Setting classpath..Kindly help...???
You might want to post a more complete message that shows the JSP Compile error. If the JSP is unable to included classes in your WEB-INF/classes directory you should take a look at bug # 10036 in the Tomcat bug database. -Original Message- From: sathya [mailto:[EMAIL PROTECTED]] Sent: 09 October, 2002 11:22 PM To: Tomcat Users List Subject: Setting classpath..Kindly help...???

RE: Forwarding in servlets.
Please remember that in both forward and send re-direct, execution of the
current servlet will resume unless you put a return statement after the
forward or re-direct statement.
if (dispatcher!=null) {
dispatcher.forward(request, response) ;
return;
}

Subject: Forwarding in servlets.
Is there any way besides the following :
request.setAttribute(selectedScreen, request.getServletPath()) ;
RequestDispatcher dispatcher =
request.getRequestDispatcher(/test.jsp) ;
if (dispatcher!=null) {
dispatcher.forward(request, response) ;
}
to forward a request to a jsp page. Is it possible to use
response.sendRedirect like in jsp ?
Any suggestions will be great.

RE: DBMS access denied with Jakarta NT Service
Don't you think the name and version number of the DBMS would be of the least bit help in solving your issue? -Original Message- From: Cinzia S [mailto:[EMAIL PROTECTED]] Sent: 08 October, 2002 2:10 AM To: [EMAIL PROTECTED] Subject: DBMS access denied with Jakarta NT Service Hi all, I'm having database access denied when running Jakarta as an NT Service, while no db access problems when running as a standalone program.
