Re: List traffic et al
I'm not sure that I agree with the idea that I have to wade through all these messages for the good of the list. As I said, I have no experience with Tomcat on Windows, so I'm not interested in Windows specific issues nor can I help to solve them. Splitting along platform lines should retain a relatively good mix of newbies and experienced developers in each list, so I don't see the problem you are pointing out. In any event, even if the list is split on basic vs. advanced topics, advanced users who wanted to help the community could subscribe to all lists. I don't think it's necessarily bad to want to subscribe only to the lists you feel you can learn from. I've been lurking and posting for about 9 months now and it seems that the same basic group of people answer a majority of the questions. I used to answer a lot more than I do now, but I'll admit that I get pretty frustrated answering the same questions over and over when I know the answers can be easily found in the archive. Is it selfish or bad of me to skip over questions I used to answer, or should more responsibility be placed on the person asking the question? (rhetorical, because there's no way to control whether or not people actually search the archives before posting...) A digest version is already available for this list. --jeff From: Dmitri Colebatch [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Date: Fri, 6 Jul 2001 16:03:14 +1000 To: [EMAIL PROTECTED], Jeff Kilbride [EMAIL PROTECTED] Subject: Re: List traffic et al I think the big problem with splitting the list is that everyone is going to be interested in their own little niche.

I even volunteered to take the lead in doing this. So I sent a note to the list owner explaining the idea. Unfortunately, I never heard anything back. Without the list owner's cooperation/participation (or someone who can modify the apache/jakarta mailing lists), it won't be possible to do this.

Trouble trying to port from JServ
Hi all, I hope someone can help me with a problem. I'm sorry if this is a stupid newbie question but I've been working on this for days with no success. I have been through all the documentation too. I am trying to port my web application from JServ to Tomcat/mod_jk and am having trouble configuring Tomcat to use the same URL for servlets that I used with JServ. Unfortunately changing the URL of my servlets is not an option because hundreds of external sites already link to these URLs. The URL I am currently using for all servlets is http://www.mydomain.com/int/MyServlet. Unfortunately under Tomcat my servlets only work at the URL http://www.mydomain.com/int/servlet/MyServlet. I think I've configured it correctly but it still won't work. I just see the following from stdout: 2001-07-06 01:49:23 - Ctx( /int ): 404 R( /int + /MyServlet + null) null Below are my conf files. I've tried several variations on them with no success. I have the following settings in server.xml: Context path=/int docBase=/opt/dev/website/int crossContext=false debug=0 reloadable=true /Context /opt/dev/website/int is the directory that contains all my servlet classes. It also contains WEB-INF/classes which is actually a symbolic link back to /opt/dev/website/int. I am not using JSP. web.xml contains the following: servlet-mapping servlet-name invoker /servlet-name url-pattern /* /url-pattern /servlet-mapping servlet-mapping servlet-name invoker /servlet-name url-pattern /servlet/* /url-pattern /servlet-mapping ... I thought this should cause all files in /int to be handled by the invoker. Finally mod_jk.conf contains the following: Alias /int /opt/dev/website/int Directory /opt/dev/website/int Options Indexes FollowSymLinks /Directory JkMount /int/* ajp12 Location /int/WEB-INF/ AllowOverride None deny from all /Location Location /int/META-INF/ AllowOverride None deny from all /Location Under this configuration the URL http://www.mydomain.com/int/MyServlet always returns 404 - Page not found. But http://www.mydomain.com/int/servlet/MyServlet returns the correct servlet response. Sorry dump all these configuration files on you but I wanted to provide as much info as possible. Can someone kindly explain how I can continue to use the same url (http://www.mydomain.com/int/MyServlet) with Tomcat? What am I doing wrong? I am using Tomcat 3.2.2 and Apache 1.3.20. Any and all replies are much appreciated. Thank you, Barry [EMAIL PROTECTED]

Re: strange way to start tomcat
The first time a jsp script is requested, it has to be compiled. This procedure takes some time. But I agree with you: Waiting some minutes is very long. What processor, memory etc do you have and is the machine loaded (use top to display the load). Perhaps you should try to use another JVM? That the sequence (start, stop, start, start) works could have following reasons: * The first time you start, everything seems to be ok. * Then you stop. * The next startup tells you, that the port is already used, so tomcat was not stopped properly. Did you do a ps -edaf to view your processes after the shutdown? Perhaps there are hanging java processes/threads? * The next time you start is the same as before: the port is used already I think that something triggers the compilation of your jsp while you perform that procedure and tomcat is not shut down at all. When you try to access your jsp afterwards, it is already compiled and so it is served faster. I would try another, more up-to-date JVM. Bye, Peter. -- Mag.

AW: User login logging (JDBC authentication)
Hi, yeah this is more or less OK. For my application i have a servlet acting as a controller (like a portal) - all functions are accessed thru the controller, which dispatches the request to the correct JSP (in your case), for my part i'm using Velocity and templates. This controller servlet initializes - initialize the user session - the logging system - messages - Database pools - The events the application can handle For every request to a protected resource (JSP), the controller checks if the user is identified. If not, the request is dispatched to the login event. After a successfull login, the login event redirects to the protected resources (which was saved from the controller before redirecting to the login JSP. I'm using a login object in the session context which knows about - the username - the language - preferences - . Hope this helps Reto -Ursprüngliche Nachricht- Von: Rajehswar V.

Problem changing default web.xml : conf/web.xml is not processed
Hi there, I have a problem changing the web.xml in the conf dir (conf/web.xml). I wanted to configure some central stuff there and wondered why it isn't working. Then I placed a wrong tag with no closing tag into the web.xml. The sax-parser must throw an exception with this file. But nothing happened. I tested the same wrong tag in an webapps web.xml file. There I got the exception. My conclusion is now, that the default web.xml is not proccessed! I wonder why, because the server.xml file is in the same directory. If server.xml is found by tomcat, why not the default web.xml. I can post a log-trace if you are intereseted, but I don't see any informative help in it. Be method opening the default web.xml does not log anything. Any comments, how I can make tomcat reading and processing the default web.xml are welcome.

Re: strange way to start tomcat
Hi Kris, thanks for the answer. I have narrowed down the problem. The default server.xml file sets tomcats to run on port 8080 as stand alone server. If i comment out the lines corresponding in the server.xml file, and run tomcat as an apache module, evererything starts smoothly, just with a bin/startup.sh command. So my problem is only on start up of tomcat as a standalone server. I still don't understand why i need this tricky sequence of startups and shutdowns, but that doesn't matter too much to me, as I is recommended to run it as an apche module ;) Alex Alex Looks like the port on which tomcat is using is being already used by something else , hence the bind exception kris

RE: Invoke New Window From Applet
Hi, from there Applet they don't invoke a new application, they only invoke a new Dialog-window inside their application (you see it by the words in the statusbar Java Applet Window). When you look at the html code, you see they have done it with the swing components. That means you only need to instantiate a new JDialog inside your Applet and invoke dialog.setVisible(true); Thats it!

problems with redirect after inserting post with form
Hello Tomcat users. I am experiencing some weird problems with my web server setup when trying to redirect after a plain form for posting data. My system configuration is: Windows 2000 server IIS 5.0 Jakarta Tomcat 3.2.2 MS SQL 2000 Avenir aveConnect JDBC-driver 2.4M (developer verison) I have built an insert post page in MM Dreaweaver Ultradev 4.0 with a standard html form (texfields and a submitm button) and a jdbc connection. After the submit button is activated and the form data is inserted (which works great) I have added an jsp redirect command, and it is here the weirdness starts. The redirect function ( response.sendRedirect(response.encodeRedirectURL(MM_editRedirectUrl)); ) doesn't seem to work if the page contains a lot of html code. With only the form tags bodyform.../form/body the redirect-command works just fine. But when nestling the form tag with tables and other formatting html code the redirect seems to break down. After pressing the submit button, the URL changes as it should and the new page is displayed, only BELOW parts of the old (form) page. How much of the old page that is included after the redirect-command is dependent on the amount of html code on the form page. Does this make any sense at all? I have spent 3 days trying back and forth with tomcat conf-files and IIS settings and so on, without any success. I have added all the context tags and so on in the conf files. Running small jsp pages works just fine. Best regards, PJ Utsi - Gothenburg Sweden
Re: strange way to start tomcat
Hello Peter, I have noticed the difference in speed you talk about when I use the mod_jk.so apache module (not stand alone mode): the first time I load the page is a bit slower than the next times. But when I use tomcat as a stand alone server, it is very very slow (order of minute...) I don't think that's my hardware (P3 933MHz) or JDK 1.1.8 on suse 7.0. Yes you are right i the standalone config, after a shutdown.sh a 'ps' command shows that the tomcat service is still running. Alex The first time a jsp script is requested, it has to be compiled. This procedure takes some time. But I agree with you: Waiting some minutes is very long. What processor, memory etc do you have and is the machine loaded (use top to display the load). Perhaps you should try to use another JVM? That the sequence (start, stop, start, start) works could have following reasons: * The first time you start, everything seems to be ok. * Then you stop. * The next startup tells you, that the port is already used, so tomcat was not stopped properly. Did you do a ps -edaf to view your processes after the shutdown? Perhaps there are hanging java processes/threads? * The next time you start is the same as before: the port is used already I think that something triggers the compilation of your jsp while you perform that procedure and tomcat is not shut down at all. When you try to access your jsp afterwards, it is already compiled and so it is served faster. I would try another, more up-to-date JVM. Bye, Peter.
creating a instance of a servlet: takes too long!!
Greetings, why is that my servlet when the first time is invoked, it takes about 30 seconds or more to start when the servlets that came in tomcat are instantaneous? After the servlet container instantiated and initialized my servlet, all the following requests are very fast. Is there any advice for what we should do and don't do in init() method? I just initialize some properties and a connection pool Well is it possible that my servlet container at any time my may shutdown my servlet to release memory, and another time it will be requested to start again and take another time too long to start, correct? How can I benchmark the time of instantiation of my servlet and the time of my init method?

Re: List traffic et al
Hi, I've been on the list about eight months and I'm not sure I agree that splitting it will alleviate the volume problem. I'm rather afraid that I would end up subscribed to 2 or 3 high volume lists rather than one. I imagine that we would see a lot of multiple posts across the lists. Previous suggestions for how the list could be split seem to me to fall into three categories 1) By platform 2) By competence (i.e. newbie list, advanced user list) 3) By category of problem Splitting the list on basis of platform strikes me as little perverse for a java based technology. However I recognise there are substantive issues because different platform = different web server. And I guess it would mean no more 'out of environment space' and 'how do i run tomcat as a service' posts but I already manage to filter most of these out anyway. My main concern would be that I'd be effectively cutting off a valuable section of the tomcat community. Whose to say the person capable and willing to solve my problem isn't running NT? And conversly why should i only post solutions to people who happen to be running the same OS as me? Problem with dividing on competence is that it is not clear how attractive a newbie list would be. Would people subscribe to a list made up of people who by definition are unlikely to know the answer to your question? Also aren't we trying to foster a strong community of tomcat/servlet developers. We would hardly be doing that by cutting newbies off from the 'experts'. After all what is going to happen? Newbies will post to their list, wait , not get an answer and repost to the advanced users list. Not a very encouraging introduction to tomcat. Dividing by category of problem seems to me the suggestion with the most merit. However here again I'm not convinced. I just think it would be incredibly difficult to get the right categories. Problems by their nature tend to cut across such neat boundaries. And half the time you don't know what category your problem fits into; that's why you have a problem. Suppose I'm trying to set up SSL. Potentially this is going to fall into all three of the categories that Sam has suggested. So again I think we are going to get multiple redundant posts and I think we completly cloud the issue of where to look for help. So what is to be done. It seems to me that good documentation projects (such as the tomcat book at sourceforge) offer the best hope for cutting the volume on this list. I know there is a big problem people posting problems which have been dealt with many, many times (sometimes in the same day!). I just don't know what you do about it other than regular reminders to check the archives before posting. And it is fairly clear that doesn't work. Last point: This list has saved my bacon a couple of times in the last eight months. As irritating as the high volume can be I think it is still very valuable in its current form. andrew On Fri, 06 Jul 2001, you wrote: I'm not sure that I agree with the idea that I have to wade through all these messages for the good of the list. As I said, I have no experience with Tomcat on Windows, so I'm not interested in Windows specific issues nor can I help to solve them. Splitting along platform lines should retain a relatively good mix of newbies and experienced developers in each list, so I don't see the problem you are pointing out. In any event, even if the list is split on basic vs. advanced topics, advanced users who wanted to help the community could subscribe to all lists. I don't think it's necessarily bad to want to subscribe only to the lists you feel you can learn from. I've been lurking and posting for about 9 months now and it seems that the same basic group of people answer a majority of the questions. I used to answer a lot more than I do now, but I'll admit that I get pretty frustrated answering the same questions over and over when I know the answers can be easily found in the archive. Is it selfish or bad of me to skip over questions I used to answer, or should more responsibility be placed on the person asking the question?

AW: creating a instance of a servlet: takes too long!!
The time it takes to start a servlet depend on following factors: - if it is run for the first time or has been changed since it was run last it will be regenerated and recompiled. Depending on size and conplexity this can take some time. - if it is the second call after a compilation it will directly serve your response. - AFAIK if it has been finalized by the servlet container it will be reloaded and your init method will be called again To measure the time in your init() method just log some timestamps like: long mStart = System.currentTimeMillis(); log(mStart + : + getClass().getName() + : + hashCode() + : started); some code/ long mEnd = System.currentTimeMillis(); log(mEnd + : + getClass().getName() + : + hashCode() +: finished after + (mEnd - mStart) + ms); -Ursprüngliche Nachricht- Von: pedro salazar [mailto:[EMAIL PROTECTED]] Gesendet: Freitag, 6.

RE: List traffic et al
I TOTALLY agree with this, deviding will not be helpful. Rather let all of us try to reduce volume(both in size and number), it does not require much effort. Lets just try to follow the following. - Please go through the archives and docs before posting a question. The members should also refrain from answering questions which are there in the docs, please refer the docs would be the best reply. - Do not post messages in non text format such as HTML, Doc or RTF. - Do not post attachments to the list (such as vCards, ms-tnef etc.) - Use a meaningful subject. A single word like ``Help!'' doesn't help in understanding the nature of the problem, and may be skipped by a person who may actually have been able to help you. It also will be helpful in ignoring the issues in whcih an individual is not interested. - Change the subject if you're changing the content of a thread drastically. - Remove extras when quoting. If the quoted message contained a standard list trailer or a long signature, do remove it in your response. - Give enough information to help your reader to help you if you're posting about a problem. Statements like, ``My Apache doesn't work'' are useless since they give no description of the problem, no idea about the methods you tried to identify the problem, and no information (logs, etc) which could help in diagnosing the problem. Give enough information (how did you set it up, what did you do to test it, what was the exact output, what did the logs contain, what versions of software/hardware were you using, etc) to enable remote diagnostics. - Research your facts before you post solutions to the list. If you're not sure of the solution to a problem, either do not post, or first make sure of all the steps and then post. If you cannot make sure, state very clearly in the message that you're not sure and that the user is trying your solution at his/her own risk. No solution is preferable to a wrong solution, which may cause immense damage.

RE: stand alone tomcat webserver question
-Original Message- From: Yomyung Leem [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 05, 2001 9:18 PM To: [EMAIL PROTECTED] Subject: stand alone tomcat webserver question Hi folks. I am quite new to this web server stuff, and I found tomcat today. What I want to know that I could not find on the web page were the following: 1. Can it handle cgi perl scripts? *.asp files? If could be made to handle cgi perl, but you would have to write it yourself - you would create a servlet that executes the perl file. The catch is that you would have to set up the shell environment according to the CGI spec (sending POST to stdin and GET paremeters to environement variables, I believe). ASP is not builtin, but there is nothing that says you can't write something to convert ASP to JSP. Sun and Oracle have announced a product about it, but I don't know any more than that. 2. ApJServDefaultPort 8007, does ApJServ have to be started even in stand alone mode? (I read that it is always required, and 8080 http port is optional. I do have a .jsp file, so I guess it is essential to have ApJServ running) AJP12 is the default manner to shutdown Tomcat. It runs on port 8007 and is only really necessary if you want to cleanly shutdown Tomcat. If you are comfortable using Unix's kill or NT's Task Manager to end processes, you don't really need it. 3. I am running this on UNIX box (Solaris 2.7), and does environment variables get passed to JVM when I start the tomcat server with startup.sh command? No. Java doesn't provide any mechanism to read environment variables from within a program and the startup scripts don't support this. One thing you could do is to iterate through the list of environment variables and create -Dxxx=yyy statements as part of the TOMCAT_OPTS. You would probably need to be careful, though, since this could very easily get very long and contain things you might not want Tomcat to know about. I know some of the questions sound pretty stupid, but I'd like to hear some answers from you. Thanks in advance. Yung

RE: creating a instance of a servlet: takes too long!!
why is that my servlet when the first time is invoked, it takes about 30 seconds or more to start when the servlets that came in tomcat are instantaneous? After the servlet container instantiated and initialized my servlet, all the following requests are very fast. Is there any advice for what we should do and don't do in init() method? Well, one option for a solution is set your servlet to load on startup and have all your initialization done at startup so that these elements are already initialized before the first request even comes. How can I benchmark the time of instantiation of my servlet and the time of my init method? I would just put in some logging code and find out where exactly the time is being taken up in your servlet(if indeed this is where it is actually munching clock cycles). --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
RE: creating a instance of a servlet: takes too long!!
Really it depends upon what you are doing in your init method. I have several servlets that load almost instantly, but don't do anything in their constructor or init methods. The only thing that you should do in your init method is to call super.init at the beginning. If you want to move the time it takes to initialize, you could use the web.xml's load-on-startup tag (see the spec for more details) to load the servlet at Tomcat startup. You servlet should stay in memory until its shutdown - Tomcat keeps a reference to the servlet, thus preventing it from being garbage collected. The only reason, I believe, that a servlet is unloaded during the middle of Tomcat execution is a newer version is detected on disk.

RE: JDBC Realm Questions Tomcat 3.2.2
Now, when somebody wants to access myServlet resource, he/she must have the role of an Administrator or Operator. I think this should be checked into the database. The problem is that, when I've tried to access myServlet for the first time, the following message was generated in the tomcat console: 2001-07-05 04:11:49 - ContextManager: JDBCRealm: JDBCRealm.authenticate: SELECT PASSWORD FROM MYUSERTABLE WHERE NAME = ? 2001-07-05 04:11:50 - ContextManager: JDBCRealm: Authentication unsuccessful for user null In the same time, the login window has appeard on Netscape browser, but after I'd entered a valid user name and password (from myUserTable) the message was the same: 2001-07-05 04:14:19 - ContextManager: JDBCRealm: Authentication unsuccessful for user null It seems for me that the user name is null every time, no matter if I enter a valid (user, passwd) or not. Is that a Tomcat bug, or I've missed something? Check your database schema and make sure it is correct. If it is all I can suggest is add some debugging code to JDBCRealm, recompile and throw it in TOMCAT_HOME/classes/, then restart and see what the actual value of username is when authenticate(String, String) is called. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

Re: creating a instance of a servlet: takes too long!!
There's another reason for this and it has to do with the java.security.SecureRandom class. From what I can tell, tomcat uses this class to generate a seed value for the session ID. The first request for a SecureRandom value (eg. new SecureRandom().nextLong()) can take many, many seconds to complete. After the first usage however, it returns immediately. I'm not sure what goes on when SecureRandom initializes but that seems to be where the slow down occurs. As a work around, you could create a low priority thread that instantiates a SecureRandom calls nextLong() then exits, and have this thread get launched by the init() method of a servlet that gets preloaded. This solution worked for me. Regards, Pete.

Hi! I have the same behave when the server (in with tomcat runs) is not configured properly with the spanish locale.

I for instance learn nothing by answering many questions that I answer, but I do learn things from reading other answers.

Even relative newbies should be capable of answering some questions that they have just dealt with the day before. I can see what you're saying, but I see a couple of problems with this. First, it's like forcing people to do something that they would/could/should have the option of doing themselves anyway. You're making it sound like people should have to read everything so that they wouldn't miss anything where they might be able to help. Well, of course, if there was a split, people who wanted to do this could still do this. And you shouldn't force people to do this. More practically, I don't think it's the most effective way to achieve your goal (more participation from people who have the answers). With a single high volume list, I believe people will tend to skim/skip more things, and perhaps even drop off the list totally. With a lower volume list, they might very well participate in the way you're suggesting -- albeit only on a subset of posts. But greater participation on a subset of posts may work out better than less participation on all the posts. For example, I see myself skipping a ton of posts because I just don't have the time; if the volume were smaller, and the scope more relevant to my interests/expertise, I would definitely participate more. (Granted that coming up with a split that will facilitate this is not trivial. But it may be worth it.) Basically, you want to make it easy and worthwhile for the more experienced people to participate, and I think a split -- a good split -- will do this. If we want to reduce traffic surely a digest is the option. The JBoss list has a _lot_ more traffic than this one, and I am able to receive that in digest mode quite happily. As has been pointed out, there is already a digest option. And this must be a personal thing, because I would absolutely detest getting such a high volume list as a digest and couldn't imagine reading it that way.

Well, the InetAddress methods do work correctly, Dave. Here is a quick demo:
import java.net.*;
public class IPGet {
public static void main(String[] args) {
try {
System.out.println(InetAddress.getByName(args[0]).getHostName());
} catch (Exception e) {
System.out.println(e);

Now, for the kicker... On one run I got the same return as you
did: the IP number instead of hostname - this happens when the lookup
fails. Therefore, I would guess right now that here might be some problem
in the nameservers at lightrealm.
So, a partial dig shows:

Are you sure there are no problems with jdk1.3.1? The main problem I found with 1.3.0 was that it shut down when you logged off. I found the same problem in 1.3.1. The fix is to add -Xsa to the execution line that starts Java in Tomcat. As for making Tomcat a service, I found the jk_nt_service.exe (zipped up) in the jakarta downloads. I thought that was the standard way of making it into a service. Is this what is causing the shutdown problem? ShouldI be using a different method? Randy Layman wrote: 1.

Re: jk_nt_service is not shutting down
I'm getting the same error (2186). It started when I added the -Xsa parameters to the Java startup, which seems to be necessary to keep the service from shutting down on logout. The problem seems to be that the service takes, as you noted, about 20 seconds too long to shut down. I'm ignoring it for now but would also like a solution. Jochen Wiedmann wrote: Hi, I am using TC 3.2.2 on several machines, all configured to be running as an NT service with jk_nt_service.

Moreover, I can see that TomCat is running for about 15-20 seconds more, which can easily be verified by deleting the log files. (They cannot be deleted until TomCat is actually stopped.) Any ideas what might be the reason? Thanks, Jochen

RE: Help on application scope
Dear all, I used a java.util.HashMap for session invalidation in my JSPs. It is declared as such in 2 jsps: jsp:useBean id=monitor class=java.util.HashMap scope=application / (GalleryViewBottom.jsp and Logout.jsp) Now the funny thing is when I issue a monitor.put(request.getRemoteAddr(), session); (GalleryViewBottom.jsp) And then try to access it from Logout.jsp the monitor has no such key value. Isn't application scope mean its accessable from ANY jsp page? I got the ideas for this code from Professional JSP (WROX, pg133 checklogin.jsp). Another way to do this, and better in my opinion, would be to write a GenericServlet which has a static HashMap member which gets initialized in init() method and has a static get and put method. Configure the servlet as a load-on-startup servlet and you're ready to go. Just import the class and do ClassWhatever.get|put(...); This will remove lines of code from the servlet generated from your jsp(autogenerated by the useBean tag). You could also include remove() and clear() methods. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

You MUST make a copy of the web.xml and put it into each webapp context's WEB-INF directory. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, July 06, 2001 12:34 AM To: [EMAIL PROTECTED] Subject: Problem changing default web.xml : conf/web.xml is not processed Hi there, I have a problem changing the web.xml in the conf dir (conf/web.xml). I wanted to configure some central stuff there and wondered why it isn't working. Then I placed a wrong tag with no closing tag into the web.xml. The sax-parser must throw an exception with this file. But nothing happened. I tested the same wrong tag in an webapps web.xml file. There I got the exception. My conclusion is now, that the default web.xml is not proccessed! I wonder why, because the server.xml file is in the same directory. If server.xml is found by tomcat, why not the default web.xml. I can post a log-trace if you are intereseted, but I don't see any informative help in it. Be method opening the default web.xml does not log anything. Any comments, how I can make tomcat reading and processing the default web.xml are welcome. Kind regards Guido --- This message is intended for the adressee or its representative only.

RE: JDBC Realm Questions Tomcat 3.2.2
Tomcat's JDBC Realm won't work with an empty database password. I posted
about this a week ago and asked if it was a bug and noone responded.
If you proved the JDBCRealm a valid username with a blank (empty string)
password, Tomcat will ignore BOTH Username and password.

Subject: JDBCRealm doesn't allow a blank password -- is this a bug?
I'm using Tomcat 3.2.2
I was just beginning to try out JDBCRealm and was continuing to get an
error. The Tomcat.log said:
2001-06-26 11:27:05 - ContextManager: JDBCRealm: SQLException:
java.sql.SQLException: Login failed for user '(null)'. Reason: Not
associated with a trusted SQL Server connection. Severity 14, State 1,
Procedure 'null null', Line 0 Unable to connect, please check your server's
version and availability.
I WAS including the proper credentials in my web.xml, so I delved into the
Tomcat source code to find what was going wrong. (this was my FIRST Tomcat
delving experience!) In JDBCRealm, method checkConnection() I found this:
if ((connectionName == null || connectionName.equals()) ||
(connectionPassword == null || connectionPassword.equals())) {
dbConnection = DriverManager.getConnection(connectionURL);
} else {
dbConnection = DriverManager.getConnection(connectionURL,
connectionName,
connectionPassword);
}
I'm practicing on an internal dev server that is poorly protected and has no
password for the username I was using, so my server.xml had:
connectionName=aDevUser connectionPassword=
Obviously, this is what is causing the problem, given the code snippet
above.
I created a new username with a real password, entered those in my
server.xml, and the problem went away.
Now I know it's not a good practice to have a password that is an empty
string, but is it an error? Should this be logged as a Tomcat bug? I'm
still fairly new to Tomcat and tried searching for this in Bugzilla and
didn't find anything and wasn't sure where to go from there. Would someone
with more experience with the process like to enter this?

Now, when somebody wants to access myServlet resource, he/she
must have the role
of an Administrator or Operator. I think this should be
checked into the
database. The problem is that, when I've tried to access
myServlet for the
first time, the following message was generated in the tomcat console:
2001-07-05 04:11:49 - ContextManager: JDBCRealm:
JDBCRealm.authenticate: SELECT
PASSWORD FROM MYUSERTABLE WHERE NAME = ?
2001-07-05 04:11:50 - ContextManager: JDBCRealm:
Authentication unsuccessful for
user null
In the same time, the login window has appeard on Netscape
browser, but after
I'd entered a valid user name and password (from myUserTable)
the message was
the same:
2001-07-05 04:14:19 - ContextManager: JDBCRealm:
Authentication unsuccessful for
user null
It seems for me that the user name is null every time, no
matter if I enter a
valid (user, passwd) or not. Is that a Tomcat bug, or I've
missed something?
Check your database schema and make sure it is correct. If it is
all I can suggest is add some debugging code to JDBCRealm, recompile
and throw it in TOMCAT_HOME/classes/, then restart and see what
the actual value of username is when authenticate(String, String)
is called.

Re: apache not able to access jsp files
I've found that setting a host to the tomcat webapps directory sort of works except that you don't get the ROOT folder. I can get to the examples via http://hostname.dom/examples/ however. I just don't get the Tomcat start page. Moreover, going ot http://hostname.dom/ROOT/ brings up the start page but the examples won't run because it's looking for them in webapps/ROOT/examples/.

turbine's database connectin pool service
Is there any documentation on how to use turbine's database connection pooling service? I'm running tomcat3.2.2 and interested in using tubrin's db pooling service only. Thanks!
Re: Apache - Tomcat - Servlet Mapping
It would probably help if the mod_jk howto contained an example showing how to run the examples through Apache. For example, I have Tomcat 3.2.2 running nicely and get the examples to run using http://servername:8080/ to launch the examples. When I connect Apache to Tomcat, using http://servername/ doesn't recognize that the / context should go to ROOT. And going into http://servername/ROOT/ gets you into trouble when it tries to go to the examples context. Eitan Ben Noach wrote: I had the same servlet-mapping problems and the right ApJServMount command is: ApJServMount /context_path/myServlet /context_path/myServlet ( You must omit the 'servlet' string from the mount command ! ) In that way Apache knows to redirect /myServlet URL to Tomcat. You can make it more straight foreword and redirect every thing under context_path to Tomcat by: ApJServMount /context_path /context_path But then also static files ( like HTMLs and GIFs ) will be directed as well to Tomcat ( which usually you don't want ) You are right, and I don't have the answer for this, that in order to redirect only servlets from Apache to Tomcat we need to write specifically the servlets url-pattern in a special ApJServMount command, which actually duplicates the information in the web.xml file. Very bad!!. Does any body have the answer for it? I have some thoughts that the using Jk_mod maybe more flexible, but didn't yet check it. Eitan Ben-Noach -Original Message- From: Colin Hawkett [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 04, 2001 9:19 AM To: [EMAIL PROTECTED] Subject: Apache - Tomcat - Servlet Mapping Hi all, This question seems to be popping up pretty regularly, but I couldn't extract a solution to my problem - namely: getting apache to recognise servlet-mappings. I am running tomcat 3.2.2 and apache 1.3.11 on win98. I have a web application packaged up as a war file and deployed to the webapps directory. The web.xml file contains (among other things) servlet servlet-nametheServlet/servlet-name servlet-classcom.myco.test.TheServlet/servlet-class /servlet servlet-mapping servlet-nametheServlet/servlet-name url-pattern/myServlet/url-pattern /servlet-mapping Now, I've confirmed that the mapping is correct by accessing it using the URL http://myserver:8080/context_path/myServlet- This is fine, no problems As I understand it, this is connecting to the tomcat web server (on port 8080), which is aware of the servlet mapping because it has read the web.xml file for application. And this is how I would expect it to work. Cool. However, I don't want Tomcat to be my web server. I want apache to be my webserver. So I try to access the application using the URL http://myserver/context_path/myServlet- This fails! everything about the web-app works with apache except the servlet mapping, so I assume Apache is unaware of it. The closest thing to a solution I have found is that I need to add a line to 'tomcat-apache.conf' that looks something like - ApJServMount/context_path/myServlet /context_path/servlet/theServlet which seems like a really annoying thing to have to do. The whole point of web-apps is that you define everything you need to in web.xml, so that you don't have to change configuration files on the deployment system. If this is necessary, then what is the point of the servlet-mapping? Surely tomcat should generate the necessary ApJServMount lines in tomcat-apache.conf when it starts up and reads web.xml? So, the big question is - * Is it possible to get apache to recognise servlet mappings defined in a web-app's web.xml without explicitly making a modification to an apache config file? If so, how? * If not can someone give a concrete example of a servlet mapping, and the corresponding ApJServMount line that will get apache to recognise that mapping? I hope this all makes sense - appreciation in advance, Colin

Works for me without any command line fixes. I thought that the -X option was added for some of the betas of 1.3.1. Is it possible that you have an older version of 1.3.1? As for making Tomcat a service, I found the jk_nt_service.exe (zipped up) in the jakarta downloads. I thought that was the standard way of making it into a service. Is this what is causing the shutdown problem? ShouldI be using a different method? You are correct. The JavaService program does basically the same thing as jk_nt_service, but it traps the OS signals and doesn't relay them on to the JVM.

Even if you think you're only using Ajp13, you probably don't want to delete this connector - it's required to shut down Tomcat.

Re: AW: List traffic et al
In a perfect world, yes, I totally agree. However, in the real world, who's going to enforce the guidelines? (we already have guidelines that few people pay attention to...) Reposting the guidelines and links to the FAQ and archive on a regular basis would probably help, and I agree that it should be done. Personally, I don't care about the volume on the list. I have a broadband connection and it only takes me a couple of seconds to download all the daily messages. However, I think Tomcat is a broad enough subject to warrant more than just one generic list. I think a couple of focused lists would help people with non-generic questions. And, as Milt Epstein points out in a later post, involvement may actually increase on smaller, focused lists. I don't think the volume on the tomcat-user list will decrease much at all, even if it is split. However, splitting will allow people with focused interests beyond getting Tomcat up and running to participate without being deluged with messages they may not be interested in. More choices are usually better than less. --jeff From: Nico Wieland [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Date: Fri, 6 Jul 2001 13:17:13 +0200 To: [EMAIL PROTECTED] Subject: AW: List traffic et al i agree 100%. i think a _good_ thing would be to include these guidelines in the confirmation message one receives after subscribing to the list. this is the way how it's done eg. on sun-managers, they post the guidelines once a month. it's the most disciplined list i know. -nico Rather let all of us try to reduce volume(both in size and number), it does not require much effort.

Thanks for all the help. It wasn't my code or my ISP, but a security manager problem...

question about classpaths in tomcat run
Hello, I specified wrapper.classpath in tomcat.properties file fora certain run and it could not findmy classes. Then I stopped tomcat and set classpath to the same destination directory and started tomcat in the same window. This time my program worked. Any clarifications about these differences -- setting classpath in properties file as opposed to setting it directly before starting tomcat ? Thanks. [EMAIL PROTECTED]

How to configure a custom page for JSP 404 errors?
Hello, This question probably has come up before, I just can't find it in the archives I am using Tomcat 3.2.2 standalone (not with Apache). How can I configure a particular page (servlet, static html, or jsp) to be the default page that comes up if the requested jsp is not found, instead of the 404 error. In other words, if a user requests: http://myTomcatSite.com/somePage.jsp I want to have somePage.jsp come up if it exists. But if somePage.jsp does not exist, I *don't* want the default 404 error to be displayed. Instead I want some custom page (a servlet actually) to be processed. I don't really care if this is achieved with a client-side redirect or a server-side include/forward. I have tried using the DefaultServlet, which doesn't seem to work. I have also set up my own servlet against url-pattern /* /url-pattern. This works for servlets only, not JSPs. It seems the basic problem is that any URI that matches *.jsp. gets processed by the JspServlet. So it is not determined if the .jsp file actually exists or not until the JspServlet is triggered. Can this custom error page functionality be configured somehow in Tomcat? Thanks for any help, Pierce Courtney [EMAIL PROTECTED]

Problem running servlets on Apache/Tomcat
Hi This query has been posted on this list quite a no. of times and even after going through the archives I'm still stuck up with this problem! To start with the configuration... I'm working Windows 2000 professional with Tomcat 3.2.2 and Apache 1.3.20. The backend is Oracle 8.1.6. I have an application called 'portfolio' for which I created a folder in C:\TOMCAT_HOME\webapps called portfolio with a hierarchy of other directories required, like C:\TOMCAT_HOME\webapps\portfolio\WEB-INF where I copied the web.xml and C:\TOMCAT_HOME\webapps\portfolio\WEB-INF\classes where I put all the servlet classes. I have put all the other files like htmls, images etc. in the C:\TOMCAT_HOME\webapps\portfolio directory! and not to forget the C:\TOMCAT_HOME\webapps\portfolio\lib dir. for all the jar files and Orcale driver... I have made changes to my servlet.xml file also to let tomcat recognize my application! Putting in the 'context-path' stuff and have edited the web.xml file to map the servlets Now I can execute my servlets but cannot run them... coz when I try exceuting them I get an error 'ClassDefNotFound: ConnectionPool/ConnectionPool' Now CoonnectionPool is actually a package(as the name impies) that i created to make a connection to the database. Its also in the classes dir. When I execute the servlets I dont get any errors as to unable to find ConnectionPool, so I presume that they are in the Path. Now I'm really stuck up and am unable to find the real problem! May be someone out there whos done something similar can help me solve this Thanks a lot in advance Priyanka __ Do You Yahoo!?

RE: Apache - Tomcat - Servlet Mapping
You could try adding the following in the TOMCAT_HOME/conf/server.xml: Context path=/ docBase=webapps/examples ../Context This will map your examples webapp to the '/'. This will allow you to access http://servername/servlet/HelloWorld. -keng wong -Original Message- From: Gary Dale [mailto:[EMAIL PROTECTED]] Sent: Friday, July 06, 2001 12:27 PM To: [EMAIL PROTECTED] Subject: Re: Apache - Tomcat - Servlet Mapping It would probably help if the mod_jk howto contained an example showing how to run the examples through Apache. For example, I have Tomcat 3.2.2 running nicely and get the examples to run using http://servername:8080/ to launch the examples. When I connect Apache to Tomcat, using http://servername/ doesn't recognize that the / context should go to ROOT. And going into http://servername/ROOT/ gets you into trouble when it tries to go to the examples context.
Re: How to configure a custom page for JSP 404 errors?
Hi Pierce, From what I've been able to gather, you should be able to set the error page using the error-page directive within the deployment descriptor for a web app (web.xml). error-page error-code404/error-code location/error.jsp/location /error-page Looking through the bug database, there was an open issue regarding the use of static html pages within the location tag. I'm uncertain at this time what release it's actually fixed in, but if you try it and get a stacktrace, then I guess you know :) The bug report can be found here: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=291 I did find this information in the archives.

But problem is I am unable to generate web.xml file with new JSP file mapping like if I give this command jspc -webxml pweb.xml -uriroot c:\myapp *.jsp the above should actualy convert all JSP files in directory myapp to *.java files by giving appropriate mapping in pweb.xml file But genrate pweb.xml file is not generated with new JSP mappings Even though if I specify mapping explicitly ,when client hits JSP page it is again converting jsp to java file in work directory.

webapp classloader ProtectionDomain (running secured tomcat)
Hi all, It seems that webapp classloader puts all classes loaded from a webapp directory into the same ProtectionDomain regardless of the location where the class was loaded from (like classes dir or a jar file). It means that any security grant entry granting permssions to a webapp codesource effectively grants the same set of permissions to each and every class in web application. This is probably fine in most cases but leaves no possibility to fine tune security within web-application. My particular problem is that I'm trying to use JAAS to enable access control with custom JAAS policy implementation. CodeSOurce partitioning that Sun suggests requires that the code sensitive to user-based operations shoud be put into separate ProtectionDomain for JAAS mechanisms to work. The only way to do this with Tomcat is to put classes someplace out of webapp directory, so they don't inherit any permissions assigned to webapp ProtectionDomain. I think that webapp class loader should put classes loaded from class directory and every jar file into diffrent protection domains, like class loaders that load classes from the system classpath in Java. Well, if all that makes any sense to you may be there's something I'm missing here?
