RE: 100% CPU Usage by upload from Netscape under Windows NT
Just one more comment on this. I have experienced a similar situation on Linux running Tomcat 3.2.1 and Netscape 6.0. (It doesn't matter whether Netscape 6.0 is local or remote) In coding a page with 1 pixel gifs which are resized to form lines and boxes (memory saving trick) Everything is fine on the first load of the page, however, if you refresh the page Netscape 6.0 will continue to request the graphics indefinitely causing very high cpu drain. It does not occur when the graphics are sized normally. I believe this to be one of many bugs in Netscape 6.0 but this one, unfortunately, effects the server. This does not occur with earlier versions of Netscape.

RE: Tomcat hangs when my ORACLE database instance is running
Do a netstat -a from your shell to see where your conflict is. Do it with nothing running, do it again with only oracle running, stop oracle and do it again with tomcat running (confirm it is running) and find the conflict. I am not familiar with Oracle on Solaris. The Oracle command console for NT has an easy stop http server button. Oracle 8i is really meant to be run on its own machine so it conflicts with other server instillations. (IIS, Apache, etc port 80 etc.) Look in the bin directory. Look in your etc/services directory to see what ports are registered. Do a search for JServ. Search the directory tree. You could always kill the process if you can identify it. If all else fails, ...read the manual. Oracle works fine without its http server running in my development environment.

Attn: GOMEZ - RE: Apache and Tomcat integration
Hello GOMEZ Henri, Everything is working great for me so this is not a call for help. Mandrake 7.2, as you mention, uses a modified version of Apache they call Apache-AdvancedExtranetServer version 3.12 (SGI). I found that in using the binary mod_jk from the Jakarta site that everything would configure correctly and produce the message that Ajp13 worker found etc. All indications in the logs were that it was working correctly, however, no forwarding would take place. Adam Fowler mentioned that he had compiled a version which works for Mandrake 7.2 and indeed it does. I am under the impression, perhaps mistakenly so, that differences in the version of Apache and even the Kernel can effect the mod_jk's performance and as such, it should be rebuilt for every unique system. I believe this to be our (the users) responsibility as there are so many variations with Linux. I only see one version of mod_jk.so available for Linux on the Jakarta site..? In hindsight, I believe that I have installed a Mandrake 7.2 with Apache and Tomcat using the original binary and it worked fine. I'm fuzzy as to whether that Apache had mod_ssl. Perhaps it was the ssl version that was needed for my most recent install. (mod_jk.so-eapi) I really appreciate your hard work with Tomcat. You and Craig McClanahan are heroes here.

RE: Tomcat Performance..
Hello, Those are similar numbers to what I have been getting on Intel platforms with Tomcat3.2.1. You can boost Tomcat to about 90 pages per second using ajp13, mod_jk, and reducing the log level to warn rather then info. (of course your Servlet code makes a difference) There is actually a bug in the logging with Tomcat 3.2.1 -- info actually gives you debug log level. According to GOMEZ the ajp13 connector is not fully optimized and mod_jk is still unfinished. Apache's performance can be boosted by limiting the modules that you use and reducing log levels as well. Interestingly, I was testing a servlet which displayed date, session variables, and generated a random password and clocked in at about 88 pages per second with mod_jk. When I direct connected to Tomcat I was able to get 463 pages per second with no errors so there is allot of potential there. I was able to top out at 1107 pages per second on that servlet with Resin. Consider your bandwidth, of course, 50-60 pages per second can easily overwhelm a T1 line. Indeed with a standard 45k+ page you would be lucky to anywhere near 25.

Well, alas I haven't been able to talk the iPlanet folks into building iWS for me on Solaris x86 yet so I can't test it that way. In testing just straight normal everyday static HTML serving between Apache and iPlanet between the two platforms I get a more expected performance difference. Where the iWS server can spit back something like 200 requests per second and the Apache server can spit back 170 requests per second. That would be what I expect. I've got a couple of other projects I've got to get done here today and then I was planning on building the Apache/Tomcat setup over on the Ultra 60 to see if the performance numbers are still skewed as much on the same platform. -- Steve Brunton [EMAIL PROTECTED] Phone: 404-827-2756 Chief Engineer Enterprise SystemsOne CNN Center, Atlanta GA CNN Internet Technologies ICBM: 84W 23' 45 33N 45' 29 * There's too much blood in my alcohol system. *

RE: Directory structure blocking
Hello, I answered this question yesterday. This is the default behavior for apache web server configured with mod_dir. (standard configuration) If there is no Directory Index page found it will display a listing of the contents of the directory. Either place a default index.html page in the directory or modify the apache httpd.conf file to route to the page that you desire. You can have many pages listed separated by a space. eg: DirectoryIndex index.html index.jsp index.php yourdesiredpage.whatever Apache will choose the first one it encounters so add yours to the end. This only takes effect after you restart apache. Comment out mod_dir, and mod_autoindex(if you have it) to turn this behavior off completely. - you can also use a .htaccess file to modify a directory(if active), or modify individual directives in the httpd.conf file.

RE: to many tomcat processes!! AAH!!
I do not know why you would want to do this other then for testing but -- change your startup script for tomcat to include the option java -classic and you will be using green threads. Be aware that it is now easier to create a deadlock situation. I believe that it would be a big mistake to deploy a system with green threads. My system incorrectly reports that I am using 217 meg of ram but that is incorrect, It is actually using 74 meg of ram.(with tomcat running) Use gps for a more accurate reading. Pushing the server hard during testing does not increase the ram used significantly. (cpu usage reflects as you would expect) All those processes that you are seeing are simply sleeping threads. They are NOT using any resources and are being incorrectly reported as consuming processes. This is the very compelling reason that you would want to use java in the first place. Native multi-threading. You have a thread pool ready to respond without the overhead of creating new processes on demand.

RE: ArrayList vs. Vector
An ArrayList will provide better performance but it is not synchronized. ArrayLists are part of the Java 2 framework. As long as you do not need your application to perform in a pre Java 2 environment it is my opinion that the ArrayList is an attractive option. The methods of dealing with ArrayLists are similar to other data types throughout the collections framework and as such you will have the ability to change your data type in the future with less effort. For instance if you decide that you need a Map or Tree. That is the goal at least. Be aware that it is not synchronized and the programmer must provide their own synchronized methods should they be needed.

RE: ArrayList vs. Vector
Hello,
I'm not really sure why you are doing what you are doing but if you need key
value pairs that can be called arbitrarily you may consider a HashMap rather
then a HashTable. Perhaps you are creating a data or object pool..? If
everything is truly read only by the servlets it doesn't seem to me that
you would need the synchronization overhead except for that brief moment
when you update the data structure. In any case a HashMap is fail-fast so
if the data changes after an iterator object is created and before it
finishes it's task the iterator will safely fail -- you could easily write
into your code to throw and catch an error there and have the process loop
by using a flag during updates. I would imagine were talking about
milliseconds. Give your unique update thread a high priority --
(Thread.NORM_PRIORITY + 2)
Are the individual elements of various object types? If not perhaps a
simple array would be the quickest as you would eliminate the casting
overhead. If you order your array you can use a binary search or simply
create a position index to call elements directly from their position in the
array. It sounds like the size of your data object is constant. If you are
iterating through your data an array would certainly be faster. Usually
simpler is better.
I wonder how much overhead creating an iterator costs? Perhaps create an
iterator pool.
Just a few thoughts. Sounds like you aren't having any troubles.

Craig

Subject: Re: ArrayList vs. Vector
Ok, that makes sense, but I don't think it applies to my case. Most of the
caching I'm doing is read-only for the servlet. I pull the info out of my
database during the init and spawn a thread to refresh the Hashtable every
six hours. By refresh, I mean I'm creating a new Hashtable object and
replacing the current cache with the new object. I'm assuming that replacing
the entire object won't wreak havoc on any current accesses -- that the
replace will wait until any current synchronized accesses have finished.
That may be a bad assumption.
In the one instance in my code where I'm doing something similar to what you
have, I'm still pulling info from my database to create the object to be
cached. If two requests come in nearly simultaneously, they'll both pull the
same info from my database and the second will overwrite the first in my
cache. No big deal, because they both contain the same info/same key. I'm
not sure if synchronizing the whole block is worthwhile in this case. Any
strong argument why I should?

Subject: RE: ArrayList vs. Vector
I still use Vectors/Hashtables when I need thread safety, though. Does
anyone know if it's faster/better to wrap one of the new
collection classes in a Collections.synchronized* class instead?
I'd expect Vector/Hashtable to be a little faster: they subclass
ArrayList/HashMap, where synchronized Collections are proxies.
But, really, neither one works.
Any places you'd use a collection, it's usually insufficient to
synchronize
the specific access: what you need to do is synchronize a block of
accesses.
For instance, here's a simple cache of Foo objects (each identified by
name), implemented with a Hashtable:
Hashtable fooCache = new Hashtable();
public Foo getFoo(String name)
{
Foo foo = (Foo)fooCache.get(name);
if (foo == null)
{
foo = new Foo(name);
fooCache.put(name, foo);
}
return foo;
}
If you only want one Foo allocated per name--always--this caching
mechanism
will break down. You'd need to synchronize around _all_ accesses to the
fooCache, whether it's a Hashtable or a HashMap. In other words,
synchronizing the table's access methods don't buy you anything--you need
to
synchronize _across_ calls. And once you synchronize it correctly,
synchronizing specific methods just slows you down.
So, you should implement the above code as,
HashMap fooCache = new HashMap();
public Foo getFoo(String name)
{
synchronized (fooCache)
{
Foo foo = (Foo)fooCache.get(name);
if (foo == null)
{
foo = new Foo(name);
fooCache.put(name, foo);
}
return foo;
}
}
This may be a peculiar case for you, but you're probably doing something
which needs similar synchronization--whatever kind of collection you're
using.

Subject: Accessing HTML files in the apache root from servlets
Greetings everyone,
I am going mad over this: I have a servlet directory structure in my apache
virtual host document root. Servlets can be reached by typing
"www.../servlet/ServletName. I am trying to access a html file from that
servlet as input data, it could be just any type of text file. Its name is
passed to the servlet in the URL:
www.../servlet/ServletName?search=inputfile.html. I would like to place that
file somewhere in the apache document root, ideally in the same directory as
the classes.
But tomcat (or the JRE from the Sun JDK, not sure) looks for that file in
the server system root if I do not specify the correct (system) path -
/usr/local/... - in the URL. First, this path is very very long, and second,
users shouldn't be bothered with the directory structure of my system (it is
really ugly).
BTW, the software versions of the tomcat engine and the JDK are, AFAIR, the
latest respective releases.
So, could anybody tell me how to tell tomcat (or the JRE) to consider the
web-documents directory as their root? Any help is greatly appreciated.
Thx in advance, Matthias
RE: Tomcat Windows NT IIS
Good, So you have tomcat running and can view the JSP and Servlet examples using port 8080. (localhost:8080/) Do not add any contexts yet. First you want to get the isapi_redirect.dll installed so that you can call the examples directly without referencing the port. If you haven't downloaded this yet get the binary from the apache site. There are several steps to follow in the IIS how to instructions. Again follow them explicitly. You will need to register the isapi _redirect.dll with IIs, modify your registry (be very careful!!), create a directory to place the isapi redirect into, and modify your workers properties file. (tomcat/conf/workersproperties) I am doing this by memory so follow your instructions carefully. Most people make their errors in the registry settings. Again it is so much easier if you print out the instructions. If you want to test some jsps or servlets that you have already made before you have the isapi working, place the jsps into the ROOT directory and call them with (localhost:8080/yourjspname.jsp). Servlets must be placed in the WEB_INF/classes directory and are referenced by (localhost:8080/servlet/yourservletname_noextention). Spend a little time getting familiar with the directories. All of your web apps go under the webapps/ROOT directory. You will know if isapi is working when you can drop the port reference and still get them. Sounds like you are getting there. Go one small step at a time, test your results, then proceed. By the time you install tomcat for the 3rd or 4th time it will only take 30 minutes. Print out all of the conf files. All your tomcat configuration is done through modifying them. They are well documented with comments. Tomcat adheres strictly to the Sun jsp/servlet APIs so those documents are worth getting familiar with as well.

I already mentioned this to Dan Milstein. It should really be checked, if that way of flushing to the physical disk (and not only to the file system cache which should be enough) is really needed. The problem becomed more important due to the fact, that the actual production release incorrectly documents the existence of a log level "warn". In 3.2.1 this does not exist. The header file for the logging declares only: #define JK_LOG_DEBUG_LEVEL 0 #define JK_LOG_INFO_LEVEL 1 #define JK_LOG_ERROR_LEVEL 2 #define JK_LOG_EMERG_LEVEL 3 #define JK_LOG_DEBUG_VERB "debug" #define JK_LOG_INFO_VERB"info" #define JK_LOG_ERROR_VERB "error" #define JK_LOG_EMERG_VERB "emerg" and if you use any undeclared log level (as e.g. warn) the code falls through to "debug". So using warn you actually produce tons of debug output, each line calling fdatasync to flush to disk. We had the same problem on the first day of a heavy load production system and had some hard hours to find out. I think the second point (incorrect log level "warn") is corrected in the next release (by changing documentation and default - not code), the first thing, throwing out fdatasync - should still be done.

I already mentioned this to Dan Milstein. It should really be checked, if that way of flushing to the physical disk (and not only to the file system cache which should be enough) is really needed. The problem becomed more important due to the fact, that the actual production release incorrectly documents the existence of a log level "warn". In 3.2.1 this does not exist. The header file for the logging declares only: #define JK_LOG_DEBUG_LEVEL 0 #define JK_LOG_INFO_LEVEL 1 #define JK_LOG_ERROR_LEVEL 2 #define JK_LOG_EMERG_LEVEL 3 #define JK_LOG_DEBUG_VERB "debug" #define JK_LOG_INFO_VERB"info" #define JK_LOG_ERROR_VERB "error" #define JK_LOG_EMERG_VERB "emerg" and if you use any undeclared log level (as e.g. warn) the code falls through to "debug". So using warn you actually produce tons of debug output, each line calling fdatasync to flush to disk. We had the same problem on the first day of a heavy load production system and had some hard hours to find out. I think the second point (incorrect log level "warn") is corrected in the next release (by changing documentation and default - not code), the first thing, throwing out fdatasync - should still be done.

RE: Cleaning up servlets
Remember that only a single instance of the servlet is created the first time it is called. It is up to tomcat to decide weather to call that servlet's destroy() method. I personally prefer that the servlet is just waiting for a request rather then being destroyed frequently as your performance will be better and servlets are idle while not in use. The effect on memory or cpu usage is extremely low (insignificant?). Your individual sessions will clean up after themselves. I have been closely monitoring this on a Linux server and have found everything to work perfectly. You can try starting tomcat with the -verbose:gc Option and watch the garbage collector at work. (beware this is allot of information) I have been very impressed with the garbage collection with Sun JDK1.3x. I also use NT2000 but haven't monitored the situation as closely in that environment.

RE: mod_jk
My understanding is that nearly any module can be statically linked within apache rather then used as a DSO. (within the Apache tree vs. mod_jk.so) This must be done during the build of Apache. The trade off is larger instances of Apache and losing the ability to upgrade the individual modules but %20* faster loading. It is on my list of things to do but I have not tried it yet as I currently have a happy family. I have read many recommendations against doing this, however, as you must thereafter completely rebuild Apache for every upgrade. I too am interested in any information from anyone who has tried this. Is there a performance boost? I personally find the mod_jk.so route to suffer in performance.

Hello, I have installed Tomcat 3.2.1 several times on NT systems using the isapi_redirect with no problems and I have been using Tomcat for about 6-8 months. I am now doing my first Linux install. The system is Mandrake Linux 7.2 with apache 1.3.12 and JDK 1.3.1 on a PIII 667 256meg ram. I have Tomcat working and have installed my package of various servlets, taglibs, and jsp pages and everything is working when I use port 8080. Apache is working great. I have switched to ajp13, and closely followed the documentation to configure apache and install mod_jk which I downloaded from the apache site. (binary) Everything has been checked at least 5 times. I am getting a little cross-eyed. I have not been able to get mod_jk to tomcat. I have my logs set to debug and after each change that I make I have restarted both servers and checked the logs. The mod_jk.log is showing that everything is being configured correctly and ajp13 is being found with each attempt yet no redirection is occurring. *mod_jk.log shows [jk_uri_worker_map.c (344)]: Into jk_uri_worker_map_t::map_uri_to_worker [jk_uri_worker_map.c (406)]: jk_uri_worker_map_t::map_uri_to_worker, Found a match ajp13 apache's access.log shows the usual 404 not found message. On each restart the note that apache is configured with mod_jk appears. Simply adding the port :8080 to the domain with the same path shows me that everything is working with regards to java and tomcat. I do have the ssl module installed in apache but it is not configured with a certificate at this time. Are there any known issues?? Any Ideas?

Developer Java 2 Platform, Enterprise Edition Technology. This certification will cover JSP and Servlet technology.
If you are an expert in JSP and Servlet technology this is
your opportunity to get involved in the creation of
a certification exam. The current phase of development is a survey, called a blueprint, that helps us weigh the
testing objectives. The survey will determine which
objectives are most important to develop questions
for. Qualifications
for this project are as follows:
- certified as a Programmer and Developer (or 1-2 years Java
Programming experience) and - experience using JSP and Servlet
technology If you
have these requirements you may proceed with the survey.
I have attached our Java based Survey tool. It will take
about 30-45 minutes to complete. Your participation in this survey will
help insure that we are testing on the appropriate
areas and that the result of our efforts will be a quality certification that is an industry standard for Java
Programming.
Survey Instructions:

If you made all of the settings in the "IIS how to" correctly it will work. The registry is the usual trouble spot. You must reboot the entire machine not just IIS. Good luck, It does work well.

RE: Tomcat broke after Oracle installation
I had the same experience with 8i Enterprise. Realize that 8i includes Apache and Jserv and you will have a conflict with ports. I just stop Apache and Jserv. For some reason you have to do it 3 or three times then restart tomcat and you are back to a happy family. It has to do with a conflict with the port that ajp12 listens on and the port that Jserve listens on. (internally not 8080...1079..??) You don't need Jserv. Just rearrange your ports and take close note of the error message that tomcat gives. Sorry but I am away from my server so I can't give you specifics. Hopefully someone is sitting near their machine and can give you the specifics.

I then used the isapi_rediredct.dll to have my IIS use Tomcat for servlets. I confirmed that worked using the examples also. My problem is, I have not been able to get IIS to recognize any other contexts. In an attempt to set up and test a new context, I copied the examples folder into a folder named "servlets" under the webapps directory. I then configured a "servlets" Tomcat context and tested it. It worked fine. When I then added the the context to uriworkers.properties and stopped and restarted IIS though, I was not able to access the new context. I kept getting 404 errors. I could tell from the error format that it was being generated by IIS rather than Tomcat. Any ideas what I might have done wrong? FYI, I'm using NT Workstation 4.0 SP6a, IIS 4, jdk 1.3. Thanks!

There is a known issue. It appears that you must insure that Tomcat only operates in a valid context. I have not faced this issue so I don't have any suggestions, however, this may be helpful. Here is a snippet from a past discussion on this issue: /* 6.11 Misconfiguration Can Cause CPU-Bound Loop If you misconfigure Tomcat 3.2 in a way that there is no valid context to handle a request (such as removing the root context and then attempting a request that should be handled by that context), Tomcat will enter a CPU-bound loop instead of responding with a 404 error. */ Hope this helps, Craig -Original Message- From: Rui M .

RE: runaway threads eating cpu cycles on Solaris 7
Garbage collection can be called by System.gc(); or Runtime.getRuntime().gc(); but this doesn't really give you control, It only suggests to the JVM to garbage collect. Solaris uses "green threads" is that correct? Are you using an earlier version of Java? (1.x) If so this can be an issue with a thread "hogging" all cpu cycles. If you are controlling threads in your applications I would suggest adding a call to yield() in your run() method. Could be a problem with thread priorities as well. I don't use Solaris so this is the best I can do. To the best of my knowledge solarus doesn't time slice.

RE: Which JVM for Tomcat?
Hello forsythe, I recommend downloading the Java 1.3 SDK. I believe it is final now..? It outperforms earlier versions and would be the best choice for your server. If you are downloading at 56k - ...oh well, just do it. It also includes all of the latest features (java 2d, java 3d, java media, etc.) It is stable and is a good performer. You need a good compiler for JSP pages. For applets, you are stuck with 1.1 and earlier if you want the majority of your visitors to make use of them. The plug in is a 2-3 meg download and it is unreasonable to expect a visitor to download that. There is also a bug in Sun's delivery system currently which doesn't allow Internet Explorer to download the plug in anyway. You will receive the latest plug in with your version 1.3. You can still compile your applets with depreciated methods. You can install multiple JDKs of different versions on the same machine.

RE: Buffering of servlet responses
I stand corrected. Since version 2.3 these are methods of the
ServletResponseWrapper. Thank you for bringing this to my attention. Tomcat
3.2 uses a servlet.jar which was updated 11/29/2000 so the capabilities of
this wrapper should be included. I tried your code and got the same result.
This seems like something that could be very interesting. Perhaps it would
be useful combined with innerHTML.?
I see you have replied. I was using the old spec. We can wait for the bug
fix then.

RE: IIS 5.0, Windows 2000 Server, Tomcat 32
I have had Tomcat 3.2 running on Windows 2000 server with IIS-5 as a stand alone configuration with the isapi_redirect.dll for about 1 month. It has been stable and performed better then I expected. My configuration is a single cpu. The documentation in the package that you download is good and will get you running fairly quickly if you are familiar with running Java apps. I also use MS-SQL7, DB2, Oracle 8I, and mySql and everything works as expected. I much prefer JDBC to ADO. The isapi_redirect.dll is pre-compiled and must be downloaded separately. Documentation is in the original documentation package. I see the advantage is that you can still use IIS with all of its functionality and native components, and Tomcat for Java. To the visitor it is seamless. Spend some extra time getting really familiar with the directory structure and all of the configuration files in the config directory. We should see a final version of Tomcat 4 soon. You can install Tomcat and play with it without affecting IIS.

The first time I call the page the URL looks like this:
http://myHost:21968/Demos/Formating.jsp

This is a serious problem because it means that someone accessing the site
for the first time, would see the result page generated by the parameters
passed by the last visitor instead of the original page.

Gaston, Tomcat will not time out and shut down as far as I am aware. It never has on me and it runs for days and weeks between reboots. Soon to be months hopefully. Perhaps it is being started by someone with less then root privileges and when they log out the process goes with them. ?.. What version are you using. I use 3.2 and JDK 1.3 and have very stable performance. Do your system resources ever become critical? Power shortages, rolling blackouts...

RE: I don't want cached pages
Thierry is correct!! When you use %! you are inserting variables into the main body of the servlet class, outside of the JSPService. This is useful for "global" counters and such but not for your use. Take a look at your preferences in your browser. I set my browsers to the minimum cache and reload on every request. That is more useful for testing.

I tried the carts.html example with the following results: - In my machine I added some articles to the cart. Then I closed my browser and opened it again. When I ran the example and added 1 more item, I noticed that all of the items I've added before where still in the cart, which didn't look nice to me. - Then I went to another computer and tried the same example. I added 1 item to the cart and I was expecting to a list with the items I've added in my computer, but I saw just 1 item. Which was perfectly fine. I opened the carts.jsp file and noticed that the bean they where using had "session" as the parameter in "scope". Anyway, I didn't used beans in my .jsp file (the one I had troubles with), but it made think it wasn't the page that remained cached but the variables I was using, so I reviewed my .jsp file and I found the problem: I was initializing my variables with something like this, %! String strOne = "", strTwo = "", strThree = ""; Double dblNumber = 0.0; Locale currentLocale; % Then I used some java code to assign these variables some values and I expected that the variables where initialized each time I called the .jsp file but it wasn't like that. Removing the "!" solved the problem. My variables are now initialized like this, % String strOne = "", strTwo = "", strThree = ""; Double dblNumber = 0.0; Locale currentLocale; % It's like if I use "%!" to initialize the variables, they are initialized just the first time the page is called, and the subsequent values assigned to them remain on the next requests to the page. Using only "%" seems to initialize the variables on each request. Do these ideas make any sense or I'm just to tired?

I've received some kind emails from the community suggesting me to include the "Expires", "Pragma" and "Cache-control" (with the appropiate values) in the header to avoid caching. This is not working, and that's because (and I'm convinced of this) it's not a browser/proxy problem. It is Tomcat that keeps the last version cached, and I'm sure of it because it's enough to restart Tomcat to solve the problem.

RE: Set up path for running the servlets
Hello Pamela, There is a configuration file located in the webapps/ROOT/WEB-INF directory called web.xml. This is the first place where servlets look for ServletConfig information. This is probably what you are looking for if I understood you correctly. This is where you add your taglibs, paths to password files, give servlets handles etc. You can download the DTD at http://java.sun.com/j2ee/tdts/web-app_2_2/dtd to see what you can do with it. You must restart tomcat for changes to take effect.

Thanks Hans, this seems to make the most sense. I was seeing this error on
multiple images, not just those in the root, and it would produce errors
like:

Haven't checked but these images were probably cached (and I was using IE5)
Still annoying though, I'm wondering if I just use apache to serve all my

I have seen this when using Internet Explorer (IE) and the resource
is cached by IE. It seems like IE closes the connection before reading
the complete response in this case, so Tomcat complains that it
couldn't write the full response. I don't see a way to fix this at
the Tomcat end. It's irritating but nothing bad happens, so just
ignore it.

What happens when you use the url http://localhost:8080/jsp/index.html ? Do you get the index page? If not make sure that you have tomcat started and all of your classpaths correctly entered. (JAVA_HOME, TOMCAT_HOME etc.) 404 error means that you have a directory misrouting issue.

Have you created a virtual directory named "jakarta" in the same folder that the isapi_redirect.dll is located? Have you assigned this directory "execute" access?

Hello, Make sure that you have set a %TOMCAT_HOME% entry into your environmental variables (ex c:\tomcat\bin ). Make sure you have set a %JAVA_HOME% environmental variable.

(the only entry I have for tomcat in my %CLASSPATH% is c:\tomcat\bin\servlet.jar ) Make sure that your JDK is in the %CLASSPATH% (are you able to javac etc. without typing the classpath?)

Good luck, Craig -Original Message-From: michael.paul3 [mailto:[EMAIL PROTECTED]]Sent: Monday, January 15, 2001 9:27 AMTo: [EMAIL PROTECTED]Subject: Redirector Failure I have a problem with using the isapi_redirector.dll with Windows NT4.0. I am trying to use Tomcat 3.1 with JDK1.3 and the NT service pack4.0. Every time I try to access any Servlets or JSPs using the redirector the web server crashes and I get a message: Dr Watson for Windows NT.Exception access violation(0x005) Address 0x10002110. I have searched the archive of FAQ's without success. I have checked the installation several times and rechecked that all the registry entries are correct. I have checked the isWorkDirPersistent="false", all without success. Does anybody have any suggestions? Would upgrading to Tomcat 3.2 or 4.0 improve the situation? Any help at all would be appreciated. Mike Paul
RE: Install the Binary Version of Tomcat
I had a similar problem and found it to be a semicolon at the end of my classpath. Look at your classpath very closely. I am running tomcat 3.2.1 on Windows 2000 server with no problems. I start tomcat by simply double-clicking on the startup.batch file in the tomcat\bin directory. This opens its own dos window. Shut it down by double-clicking on the shutdown.batch file which closes the dos window. You can make a shortcut on your desktop. Hope this helps.

D:\jakarta-tomcat-3.2.1\bin\startup a new window (Tomcat 3.2) would appear for one/two seconds, then it killed itself immediately!? Try opening a DOS window, change to the D:\jakarta-tomcat-3.2.1\bin directory, and run: "tomcat run" This should run tomcat in the same window, so you can see the error messages. Also check the logs in jakarta-tomcat-3.2.1\logs.

RE: Installation on Windows 2000
I just installed Tomcat 3.2 on windows 2000 Server yesterday and it went rather easily. Everything works great! :0) Print out and read the documentation that comes with the download before you begin. Also print out the server.xml, tomcat.xml etc all of the configuration files. The documentation is good. There are about 25 steps or more including modifying your registry so be careful. Preparation and a hard copy in hand are the keys. I would estimate that I could do the entire procedure now in about 2 hours although it took about a day the first time. This morning I was able to set up MySQL with tomcat as well. Sql-Server7 and DB2 to come over the weekend. I chose to use the isapi_redirect.dll and a stand alone configuration as it appears to be the most stable and still allows full functionality of the existing IIS-5. This means several configuration files must be dealt with. Speed with my personal servlet library seems better then ASP and Visual Basic. JSP pages will be slow the first time they are run but performance is very good afterwards. (they must compile) Tweak the workers.properties file to get maximum performance. Don't drink too much caffeine and use a "Zen" approach and it will come together. Take some time to really learn the directory structure. You can set directories to automatically reload.

Windows 2000; 2. Windows NT 4.0 Workstation. Thanks, Shicheng PS: JRun from Allaire Corporation is an expensive software which supports JSP; so what is the difference between JRun and Tomcat? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
