RE: Failing a JK Worker thread
We have an application running as a webapp which requires legacy systems and network resources which are not fault-tolerant. Luckily these resources are stateless. So we have replicated these resources so that one is available per tomcat instance. When we attempt to use one of these resources from within the webapp and it fails, we need a way to try the next pair (tomcat legacy) in the group. This will allow us to provide a balanced fault-tolerant service with a webapp interface. Since the tomcat instance is responding and functioning, the reply_timeout was not met so apache webserver considered the request a success. Providing a application error from tomcat (maybe a 503 or 401 instead of 500) seemed like the rightest way to do it. I see a few other options: 1. Put a layer on top of apache that tests the response and makes a new request. This doesn't buy us anything and circumvents the use of jk 2. (some how/maigcally) Send an out of process message from tomcat back to apache that the resource is down. 3. Modify AJP to handle this error (this may already have a mechanism that I missed) Does any one have any other suggestions for ensuring reliability when there is a 3rd party piece of hardware/software which your webapp relies on that has no fault-tolerance of its own? I may be totally missing the point here, but isn't this something that could be handled in a servlet filter. If you have an availability problem, set a flag in the response header that the filter can check for and take appropriate action?

RE: How to get know what version of TC is running behind Apache
Hi all, Is it possible to know what version of Tomcat is running behind an Apache. The connector used is JK. Try asking for a non-existant servlet in your web-app. The 404 page is issued by Tomcat and, I think, tells you the version.

Multiple mappings to same servlet query
Hi I know that if I have multiple mappings to the same servlet, then I get two seperate objects instantiated. However, where does the engine instantiate the copy from? For example, I want to run two copies of the same servlet with different URLs, one in test mode, one in live mode. I was planning on configuring a different set of parameters for the two cases in my web.xml file but I need to be sure that I will get two instances, each with its own set parameters rather than the engine cloning a copy of the servlet it has already loaded.

HttpServletInputStream is corrupting data?
Hi I don't think that this is a Tomcat problem per-se, but it involves Tomcat so I'm asking here in the hope that someone else has seen this before. An external program reads XML from a file on disk into a ByteArrayOutputStream to calculate the length of the data. The byte array is extracted from the stream and written to the OutputStream of a URLConnection object which is pointing to my servlet running under Tomcat 4.1.31. The servlet reads the XML from the HttpServletRequest InputStream and performs an XSLT transformation on it. If I point the URL to the normal port 80, the request is routed through Microsoft IIS server and passed to Tomcat. The input stream read by Tomcat is corrupt - parts of the file are missing. However, if I point the URL to Tomcat directly via port 8080 everything works fine. I've verified that the original disk file is valid, the byte array created by the external program is correct and contains correct data and that all the correct data is written to the URLConnection by the external program. Has anyone either seen something like this before or have any suggestions as to where to start looking.

RE: HttpServletInputStream is corrupting data?
I'd worry about character encoding if I were you. I bet someone is transcoding. I'd thought about that, but if it was an encoding issue, wouldn't I expect the same problem regardless of whether I routed the request through IIS first or sent it directly to Tomcat? The XML header specifies iso-8859-1 - I wouldn't have expected a problem in a UK locale with this.

RE: performance/scalability impact of many webapps in one container
For reasons beyond my control, a web application (apache/Tomcat/PostgreSQL) that I support will need to be partitioned into one context per customer (to support one database per customer). I'm wondering: Do you really need one database per customer? In a similair situation, we resolved this by adding a client code to all our database tables indexes. Each customer/client was given their own URL to access the system and a filter used the incoming url to load a client code into the request headers before passing the request to a single servlet.

RE: Tomcat fails - Can't read body, waited #0 Seems size related
Hi, Ahh, it's great that you tried this: I was just going to ask if the connector is to blame ;) The range of data sizes you mentioned immediately starts the buffer size alarm horn in my head ;) 8192 = 8k is the default buffer size for many connector versions, including probably the one you're using. See if adjusting the buffer size (if it's possible at all) to a higher value like 16K makes this go away. Hi Yoav Thanks for your response. Any idea where I should be looking. I've found the AJP13 config entry in server.xml but there is nothing that looks like a buffersize parameter. I've looked on the AJP13 page at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html and that doesn't seem to mention buffersizes either.

Is it possible to force Tomcat to drop a servlet?
Hi I'm experiencing odd failures when a servlets init procedure is called for a second time. What I *think* is happening is that Tomcat is deactivating the servlet (as it is allowed to do) but some of the singleton objects created by the servlet initialisation routine are not being culled at the same time. As a result, when Tomcat receives a request for this servlet and starts to re-load it, my servlet is falling over when it tries to create objects that already exist. Obviously this is a logic problem with my servlet rather than with Tomcat but so that I can test my theory (and soloution), how can I force tomcat to drop my servlet and reload it under controlled conditions without re-loading the entire web-app? Reloading the entire application through the manager doesn't appear to exhibit the problem.

Class Load Order
Hi In what order does Tomcat search ./common/classes, ./shared/classes and ./webapp/classes for .class files? I have a number of web-apps that use class files located in ./shared/classes to connect to a backend ERP system. There has always been an implicit assumption that there would only ever be one backend system hence locating the class files in ./shared/classes - that assumption was blown apart this morning.

RE: Serving up static content through apache using mod_jk
Hi, As always, consider using tomcat standalone for all your traffic, static and dynamic. This is the third time I have heard this piece of advice recently. When I started off with Tomcat back in the 3.x days the recommendation was always to run Tomcat for the dynamic servlet/jsp stuff and a real web server (Apache/IIS) for the static content. Are we now saying that Tomcat is as good a web server for static content as is Apache?

URL Mapping Question
Hi I have Tomcat 4.4.18 running behind Microsofts IIS web server. In IIS I have two virtual directories defined InboundA and InboundB both of which are mapped to the same physical directory $TOMCAT_HOME/webapps/Inbound. In workers2.properties I have added the lines ... [uri:/InboundA/*] context=/Inbound [uri:/InboundB/*] context=/Inbound and I have added the context Inbound to the server.xml in $TOMCAT/conf After restarting IIS and Tomcat, the Tomcat manger application sees the Inbound context loaded and I can run the servlets contained in the context by accessing Tomcat directly via port 8080 (http://hostname:8080/Inbound/servletname, however when I use the browser to access http://hostname/InboundA/servletname or InboundB I get a 404 response from IIS rather than a response from Tomcat which implies that the forwarding is not taking place.

Tomcat and restricting the size of HttpServletRequest
Hi I have an application where a client transmits data to a servlet by opening a URLConnection to the servlet and writing the data to the outputStream as a POST request which the servlet processes by reading the HttpServletRequest inputStream. What can I do to protect my servlet against a rogue client that opens the outputStream and trying to write multi-gigabytes of data and running the server out of memory or does Tomcat already have mechanisms in place to prevent this.

RE: Tomcat and restricting the size of HttpServletRequest
There is a max POST size limit attribute on the Connectors. Otherwise - you can code for it too: request.getContentLength() == Size of posted content. -1 if the client did not provide a Content length. I wondered about request.getContentLength() but was worried that it was calculated by Tomcat rather than relying on it being set by the client. Either way, if the client doesn't specify the length or lies about it then I'm still in danger of running out of room. This also begs the question as to when my servlet gets to see an incoming request - I was concerned that by the time my servlet gets to see the incoming request Tomcat had already read the incoming data and stored it in the HttpServletRequest object - in which case request.getContentLength() is of no help.

RE: Tomcat and restricting the size of HttpServletRequest
I remember a previous discussion on this and one of the solutions was to use an applet that would check the file size prior to transmission. I can do that if the remote end is using my client - my concern is that once the URL is known anyone could write a program that writes huge amounts of data to that URL. Is this not a general problem for any servlet that receives data in a POST request over the internet? Is there anyway to monitor the size of the object as it is uploaded and terminate it if it exceeds a certain size? Just a thought. I guess this what I'm asking :) Regards Roger There is a max POST size limit attribute on the Connectors.

RE: Tomcat and IIS Web Server
IIS will handle the https. That means that actually the connection between IIS and tomcat is not secure, so take that into consideration as you make your decision. Thanks Daniel. Both the IIS server and Tomcat are located on the same server behind a firewall - so that really shouldn't be an issue should it? Even if they were on different servers behind a firewall given that I'm not worried about internal snooping it's still not an issue - or am I missing something important here?

jk2.properties and
apache workers2.properties. If you comment out one, you have
to comment out
another.
It's not in jk2.properties. My jk2.properties is empty, in so far as all the
entries are commented out. [shm] appears to be required in
workers2.properties otherwise the isapi_redirector2.dll complains. I'm not
using Apache, I'm using IIS. I've attached my jk2.properties and
workers2.properties below.

Roger

Subject: RE: Tomcat 4.1.18, JK2 - no iis_redirect.log
has been the
major cause of my problems in getting Tomcat to work. For
example, I only
found out about the need for [shm] through the archives of
this list.
[shm] is needed section is needed to run i_r2.dll ?
i'll test this.. shouldnt be needed at all.. or at least have a
plausible default that to not cause any problems if not needed..
I think it's a bug.. Please report this issue at
http://nagoya.apache.org/bugzilla.. Thanks..
If I try to start Tomcat without
[shm]
file=e:\java\jakarta-tomcat\logs\shm.file
size=1048576
in the workers2.properties then I get [Thu Feb 06 16:00:41
2003] (error )
[jk_shm.c (333)] shm.init(): No file in the tomcat logfile
and I cannot
load the examples webapp.
Before I report this as a bug I need to tidy up what I've
been doing, I've
been trying to get this to work for a couple of days now and
it is entirely
possible that I've got some crud/unneccassary configuration
floating around.
Incidentally, does the path http://domainname/global/ have a special
meaning to Tomcat 4.x. I have a web application global that
I have not yet
mapped into server.xml yet, but trying to load a static html page
domainname/global/default.htm is returning a 404 from
Tomcat rather than
finding it with IIS which I would have expected.

Roger

sendRedirect() fails on first call only within a session
Hi I'm using IIS to serve the top level html pages from a web application that runs under Tomcat 3.2. The first page (default.htm) in the top level directory (http://domain/applicationname is displayed and prompts for userid and password and passes this data to a servlet /domain/applicationname/servlet/doLogin in a POST request. If the userid/password is invalid the servlet issues response.sendRedirect(response.encodeRedirectURL(../default.htm)); to redisplay the original form. What actually happens is that if an invalid password is entered into default.htm when it is displayed for the first time in a session, the redirection displays the standard IIS 404 Not Found page. If I then navigate back to default.htm by either using the browsers back button, or re-entering the URL in the adress bar and re-enter an invalid password, then the re-direction call works and re-displays default.htm and will continue to do so for as long as I keep entering invalid passwords. Any ideas what's going on? Regards Roger -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: sendRedirect() fails on first call only within a session
I've done some more investigation. If I replace 'response.sendRedirect(response.encodeRedirectURL(../default.htm))' with 'response.sendRedirect(../default.htm);' then everything works as expected, so there is something about response.encodeRedirectURL() that I'm not uderstanding. I've looked through the isapi.log and I've noticed that when using response.encodeRedirectURL() that the resulting call for the first call (and the first call only) in a session is something like /application/default.htm;jsessionid=0c1stutim1 - which is the correct path. I was wondering, could IIS be considering the ';jsessionid=' string as being part of the actual path to the page?

URL mapping problem
Hi (Tomcat 3.2, IIS 4.0 Win NT5.0 Sp6) I have a commercial web application (to which I have no access to the source) that exists in two configurations (i.e two sets of web directories below Inetpub/wwwroot). The application ends by calling exit.htm in their respective html directories (ipshtml and elcomhtml). I need to do some extra processing and want to replace these calls to exit.htm with calls to servlets that exist in a Tomcat web application. Each call needs a different servlet although they are in the same Tomcat web application I've put the following entries in uriworkermap.properties (one for each of the applications) /ipshtml/exit.htm=$(default.worker) /elcomhtml/exit.htm=$(default.worker) and after restarting both tomcat and IIS, I can see from the isapi.log that IIS is correctly identifying both these calls as servlet URLS and hands off to tomcat. What I'm having problems with is configuring the web.xml file to find the servlet. I started with servlet-mapping servlet-nameExitReplacement/servlet-name url-pattern/ipshtml/exit.htm/url-pattern /servlet-mapping servlet-mapping servlet-nameElcomExit/servlet-name url-pattern/elcomhtml/exit.htm/url-pattern /servlet-mapping but calls to either ipshtml/exit.htm and elcomhtml/exit.htm both return 404. If I change to servlet-mapping servlet-nameExitReplacement/servlet-name url-pattern/exit.htm/url-pattern /servlet-mapping servlet-mapping servlet-nameElcomExit/servlet-name url-pattern/exit.htm/url-pattern /servlet-mapping then Tomcat logs that it's removing duplicate exit.htm's during startup and calls to both /ipshtml/exit.htm and /elcomhtml/exit.htm resolve to ElcomExit. If I reverse the order of the servlet mapping entries then both resolve to ExitReplacement. So, how do I map /ipshtml/exit.htm to ExitReplacement and /elcomhtml/exit.htm to ElcomExit when both ExitReplacement and ElcomExit exist in the same Tomcat Web Application. I hope that this makes sense. Regards Roger -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: URL mapping problem
Howdy, You realize one page can only map to one servlet, right? There can only be one /exit.htm for your webapp. My mistake, I assumed that Tomact would see /ipshtml/exit.htm and /elcomhtml/exit.htm as two. You can, however, code that servlet to see whether the request came from ip or elcom and do different things accordingly. No problem, thanks for your help.

RE: JSP source
Hi I want to do some reporting that is to be called by a cron job. I do not want to use a reporting tool. Can use JSP * to talk to the database * fetch the relevant details * format the details as a report * fetch the HTML source of the generated report * and email it to intended recipients My doubt is is it possible to fetch the HTML source of a JSP? I know I could use java mail to email if I could manage to get the source. Please pour in your suggestions This is probably not what you want to hear, but if I had to do this, then I would be looking to provide the report data as XML and then use an XSLT stylesheet (call it your template if you wish) to transform the XML data into HTML or whatever I wanted.

RE: Java method equal to perl crypt()?
The only problem I have is if I migrate to JSP, how can I compare passwords that are supplied in the JSP page to the password in the DB that was stored via the Perl crypt() function? Assuming that the Perl crypt() function is an implementation of the Unix crypt command then try either http://manticore.2y.net/Java/examples/crypt.zip or google for Jcrypt.java Regards Roger -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: servlet communication
Could you just rely on the manager application to reload the webapp? Then there is no code to maintain. I've been looking for an effective way to emulate the unix 'kill -HUP' command for ages. It's not always practical to kill off the webapp, since you need to ensure that no-one is using it at the time. Otherwise - your in a kludge. You can: - Put a status object in your application context - When a servlet is executed - it can first check its status instance locally stored against the application version. If out of sync - the servlet can reload its config. But this requires a syncronization block on the servlet which is a pain. IMO - Use the manager app. You may be able to minimise the synchronization effect by adapting the technique used by the fast collections implemented in the Apache Commons project. These allow unsynched read access unless a change is taking place, in which case the read access is only synced until the change is finished.

iis_redirect.log
Hi I'm using Tomcat 3.2 as a servlet engine for Microsofts IIS. Is there anyway that I can either force the iis_redirect.log to rotate on a regular basis, or stop/reduce the volume of data that's getting spat into the log file.
