myapp's problems with 4.0.*
Dear List, This is the context of my app from the server.xml. It seems that the app works o.k with Tomcat 4.1.* but not 4.0.*. As you will see we are using the Oracle driver and we have both the necessary oracle jar files in the %CATALINA_HOME%\common\lib directory. Could anyone explain why this might not be working with 4.0.* ? This is not so bad it is an older version, but it would be nice to explain why it doesnt work ;) I would really appreciate (again) any pointers. regards Ben Bookey. === Context path=/myapp docBase=D:\Tomcat\Apache Tomcat 4.0\webapps\myapp reloadable=true Logger className=org.apache.catalina.logger.FileLogger prefix=myapp__log. suffix=.txt timestamp=true/ Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=oracle.jdbc.driver.OracleDriver connectionURL=jdbc:oracle:thin:@146.140.211.60:1521:ingeo connectionName=myappdb connectionPassword=myappdb userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ Resource name=jdbc/myoracle auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/myoracle parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter parameter namedriverClassName/name valueoracle.jdbc.driver.OracleDriver/value /parameter parameter nameurl/name valuejdbc:oracle:thin:@146.140.211.60:1521:ingeo/value /parameter parameter nameusername/name valuemyappdbuser/value /parameter parameter namepassword/name valuemyappdbpwd/value /parameter parameter namemaxActive/name value20/value /parameter parameter namemaxIdle/name value10/value /parameter parameter namemaxWait/name value-1/value /parameter /ResourceParams /Context - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Can server.xml be reloaded without restart?
The context is your application so (context)/META-INF is right beside
your (context)/WEB-INF.
Tomcat will know whch host to use because that's where you deploy it (if
you use the deployer) or you can stick the app in the host's appbase
folder, and it'll work it out. It did with me anyway. Once it's
deployed, have a look in conf\Catalina and you find equivalent
context.xml files in there too.
As Apache acknowledge, they just write software that they give away for
free, and documentation and support are just extras when they get time.
There are a couple of books on Tomcat that go into more detail and
explain how things work. (Again, my experience).

What do you mean by {context}/META-INF?
What the hell is {context} ?
And still, how would it know which Host to use?

Correct.

{context}/META-INF
To answer your other question: this file is associated with the webapp
because of its location in the context dir or WAR file. That's how the
manager app/Tomcat/etc know what to do with it.
I don't know what's up there now, but this was described on the Tomcat
site when I made the switch to using context.xml many moons ago. ;)
In fact, for Tomcat5 use of context.xml is encouraged.

Ok, I get it now... But is there any way to make it so that you can add new
www.domain.com aka virtual hosts without restarting the server?

hanging application and broken pipes
Hi,
I am looking for some advice on tackling the following problem.
We have to maintain an application not written by us, and about three times
a day the server hangs.
We are using tomcat 4.1.29, oracle 8 and use connection pooling.
Upon calling a certain method: readDidactischTypes() (don't mind the
language mixing), the log should print:
2004-06-07 00:04:32 kwaliteitskaart.SchoolsBean[4402]: readDidactischTypes()
2004-06-07 00:04:32 kwaliteitskaart.SchoolsBean[4416]: SELECT DISTINCT
vis.vis_code AS dedactTypeCode, vis.vis_omschrijving AS dedactTypeName FROM
ins_visies vis ORDER BY vis.vis_omschrijving
The log query action is the first thing printed AFTER getting a connection
from the pool, in other words:
public DidactischTypeBean readDidactischTypes()
{
log(readDidactischTypes(), 4402);
DidactischTypeBean didactischTypeBean = null;
DidactischTypeDetailsBean didactischTypeDetailsBean = null;
Connection conn = null;
PreparedStatement stmt = null;
ResultSet rs = null;
int didactCounter = 0;
int rowCount = 0;
try {
didactischTypeBean = new DidactischTypeBean();
conn = getConnection();
log(SQL_all_didact, 4416);
(don't mind the cumbersome logger either ;-)).
Now sometimes during the day, the following happens:
2004-06-07 13:34:50 kwaliteitskaart.SchoolsBean[4402]: readDidactischTypes()
2004-06-07 13:34:51 kwaliteitskaart.SchoolsBean[4402]: readDidactischTypes()
... and this about 20 times more.
2004-06-07 13:37:21 kwaliteitskaart.SchoolsBean[4402]: readDidactischTypes()
2004-06-07 13:37:31 kwaliteitskaart.SchoolsBean[4402]: readDidactischTypes()

My questions are:
- does anybody know how to identify different clients in the log, can I
print an ip for example after each timestamp?
- does anybody know what the 'waiting for 276 instances' means, does it
mean I have 276 concurrent clients?
- did anyone experience a similar problem and found a solution ;-)?
- does anyone have any pointers of how to detect where the application or
the server goes wrong?
The application uses jsp's and almost no servlets except a pdf and
fopservlet. It does use thirdparty libs such as classes12.jar for oracle
and the commons-dbcp
Thank you very much in advance for any advice you can offer.

Cluster not working properly
Hi, I'm having a problem with replicating session information in my clustered webapp. Let me first introduce my scenario: I have two TC instances 4.1.18 running on two different machines. On one of them I also have an Apache front end for the two TC and let mod_jk balance the load between them. I also have the InMemoryReplicationManager (tomcat-replication.jar from Filip Hanik for T4. Then I tested it with the SessionExample in the example-Context and it worked great. Whenever i add something into the session I can see in the console that the data gets replicated on both TC instances. Therefore one TC instance can fail and the application still keeps on working. Then I inserted the SessionExample into my own Context to test the replication mechanism in that context as well and adjusted the Context definition for my webapp on both TC instances accordingly Unfortunatelythe replication no longer works.. But the session info never gets replicated on the other TC instance. The only thing I'm currently seesing is Caught 'java.lang.NullPointerException' closing channel in the console. Does anybody have an clues as to what is wrong here? Mit freundlichen Grüßen A.

[ANNOUNCE] Servlet Utilities 0.1
I threw together a few filter utilities. Everything (including source) can be
found here:
http://funkman.home.comcast.net/
Utilities of interest:
*TimerFilter* - A Filter that lets you spew out how long it took to serve a page.
*ErrorFilter* - Spit or an error code and a file or message.
*NoCacheFilter* - Set all the appropriate no cache headers
EL Wrapper - Make it easy to use EL expressions in servlets or dynamically
use EL expressions in JSP's.
All 3 filters extend a class called ConditionFilter. ConditionFilter allows
you to decide when the Filter will execute. It's default implementation
allows you to use an EL expression. For example:
filter
filter-nameErrorFilter/filter-name
filter-classnet.funkman.servletutil.filter.ErrorFilter/filter-class
init-param
param-nameerrorMessage/param-name
param-value ![CDATA[bTHBBBT!/b]] /param-value

AW: JK2: lb_factor
Yes, I'm still struggling, too, and have quite similar problems now - I added a third server to the load balanced cluster, but only two of them get requests. I shut down each server in turn, and the load got balanced fine between the remaining two - on starting up the third server again, one always becomes idle (not always the same, above all...). Not talking about the fact that setting lb_factor to whatever value doesn't seem to have much effect on the load distribution... At least, I found out that lb_factor has nothing to do with a factor, indeed - assume that each worker has an initial lb_value, set to it's lb_factor. With every request, a worker is chosen, its lb_value gets increased by its lb_factor, and if it's smaller than lb_value of the other nodes, that worker gets the request. If lb_value is 255, it gets resetted to 0. ^^ Just search archives of Apache User Mailing List, found it there (and hope I understood correctly) - however, the mail was from some months ago, so I really don't know if it still works like this. I'd really like to know if someone has managed to build a cluster of more than 2 Tomcat servers, using Apache + JK2, with working loadbalancing? Just curious... If someone could give a hint why it does such strange things (like ignoring cluster nodes), we'd of course be thankful, too... :) Greets, Nicole -Ursprüngliche Nachricht- Von: Kommuru, Bhaskar [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 17.

RE: [ANNOUNCE] Servlet Utilities 0.1
Hi,
You know, when I was putting the balancer app in tomcat proper, I was
thinking it'd be great if we had a place for these extra things that
don't quite belong in tomcat itself, but are useful accompaniments. We
could do this any number of ways, such as sourceforge or a contrib
section of the tomcat CVS, but at the time I was too lazy to pursue.
Now that I see these filters, I think they belong in the same space, so
maybe it's time to think about this a bit further.
Of course this comes up when I'm going on vacation ;)

I threw together a few filter utilities. Everything (including source)
can
be
found here:
http://funkman.home.comcast.net/
Utilities of interest:
*TimerFilter* - A Filter that lets you spew out how long it took to
serve a
page.
*ErrorFilter* - Spit or an error code and a file or message.
*NoCacheFilter* - Set all the appropriate no cache headers
EL Wrapper - Make it easy to use EL expressions in servlets or
dynamically
use EL expressions in JSP's.
All 3 filters extend a class called ConditionFilter. ConditionFilter
allows
you to decide when the Filter will execute. It's default implementation
allows you to use an EL expression. For example:
filter
filter-nameErrorFilter/filter-name
filter-classnet.funkman.servletutil.filter.ErrorFilter/filter-class
init-param
param-nameerrorMessage/param-name
param-value ![CDATA[bTHBBBT!/b]] /param-value

RE: How can I inhibit web navegation?
Well, you can stop directory lists by setting listings to false in web.xml in /tomcat/conf (the global web.xml file). There are comments about it in the file. As for the navigation thing, you can externalize your security with something like Netegrity Siteminder. This will allow you to stop users from accessing any page of your application except those you define as unprotected, unless they have a valid session established. However, you can do much the same thing within your application, and I think this is what's generally done. On each request, see if a valid session exists. If not, redirect to some logon page, or whatever is appropriate. That takes care of PART of the problem. The other part is once a session IS established, there's not really anything to stop a user from going to any URL they can properly construct. One way to handle that is that on each request, you set in session what page was being viewed. Then, you check that whatever page was last being viewed is a valid predecessor to the page being requested. In other words, if the user is on page A, then you might know that in your application flow it's only ever valid to go to Page B, never directly to page C. So, when page A is requested, yiou set in session a flag to say page A was last being viewed. Now, when page B or C is requested, you check that value. If page B is requested and the value is A, then you know you are OK. If it's anything else, redirect the request. Hope that helps!

RE: JK2: lb_factor
In my case, I have 4 tomcats, 2 running locally and other 2 remotely. I have noticed onething here.. Loadbalancer is giving preference only to local servers.

RE: JK2: lb_factor
Yes, right, that was the mail I meant. Your assumption about failover instead of load balancing seems to be correct, at least, at my cluster (one local server, on a remote machine another server + VMWare with a third server) it is the same - thanks for that comment, I was to blind to see it myself. ;-) I'll try to find out more tomorrow, maybe we'll get it to work - I'd be very interested in your progresses, however. Do you've got any idea how to realise load balancing with a defined distribution? Or, in other words: as long as it does not work properly with Tomcat mod_jk2, are there any reasons to use those, after all, instead of Tomcat's balancer-webapp, if one is mainly interested in performance issues? -Ursprüngliche Nachricht- Von: Kommuru, Bhaskar [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 17.

Adding roles to users
I have been able to create a user by calling the createUser method on the Users:type=UserDatabase,database=UserDatabase object. Now I need to add a role to that user. In the mbeans-descriptors.xml file it describes the return value as being the name of the user bean. The source for MemoryUserDatabase returns the full name of the user created. The return I get from my call to createUser with the full name supplied is null. I now have two questions: 1. What is the name of the object I should use to manipulate an individual user? 2. How do I set the desired user active so I can update the correct user? I have a hard time following the code for the admin app because the code is so abstracted and I don't know where all of the property strings and attributes are coming from. Robert S.

All threads are busy ... servlet status 75
Hello everybody. I receive an error like the above and then Tomcat stops to respond. I searched the archives about this error and found that a lot of people also had this, but I didn't find the solution in the answers. Sometimes it was suggested to upgrade to 4.1.29, but that's what we are already using. What I found is, that there were no more messages in this mailing list about this bug since begin 2004, so maybe 4.1.30 solves this ? We are running Tomcat on Redhat Linux with kernel 2.4.9-e.27smp and Java SDK 1.4.2-02-b06. There is also Oracle 9i running on that server and it Tomcat/JSP is used to generate a WEB application from database information. This is quite URGENT, because this is a system going productive soon and will run 24/7. Any idea ? Has there been a solution for those which had the problem earlier (in 2002/2003) ? If needed I can post catalina.out messages, configuration files etc. With kind regards, Harald Henkel -- Harald Henkel GS automation GmbH Winterstraße 2 82223 Eichenau Germany Tel:+ 49-8141-35 731-37 Fax:+ 49-8141-35 731-38 Mobile: + 49-178-7829126 e-mail: [EMAIL PROTECTED] Web:www.GS-automation.DE - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi, No, they can't be viewed directly: the servlet container is prohibited from serving content under WEB-INF directories by the Servlet Specification.

I shut down each server in turn, and the load got balanced fine between the remaining two - on starting up the third server again, one always becomes idle (not always the same, above all...). Not talking about the fact that setting lb_factor to whatever value doesn't seem to have much effect on the load distribution... At least, I found out that lb_factor has nothing to do with a factor, indeed - assume that each worker has an initial lb_value, set to it's lb_factor. With every request, a worker is chosen, its lb_value gets increased by its lb_factor, and if it's smaller than lb_value of the other nodes, that worker gets the request. If lb_value is 255, it gets resetted to 0. ^^ Just search archives of Apache User Mailing List, found it there (and hope I understood correctly) - however, the mail was from some months ago, so I really don't know if it still works like this. I'd really like to know if someone has managed to build a cluster of more than 2 Tomcat servers, using Apache + JK2, with working loadbalancing? Just curious...

IIS, Tomcat 5, Win2K issue
I am having an issue with connecting Tomcat to IIS 5. I am trying to use the isapi_redirector2.dll. Everything appears to be installed correctly, I am getting a green arrow. Tomcat works fine when accessed with the standalone connector. However, when trying to request the tomcat example context through IIS, I get a Cannot find server or DNS error message. If the redirector isn't installed I get Page not found. The only issue I can think of is that this server has two network cards and three IP's assigned to it. My question is, should I bind the AJP connector to a particular address or leave it localhost. Currently it shows up this way in the stdout.log: Jun 17, 2004 11:53:00 AM org.apache.jk.common.ChannelSocket init INFO: JK2: ajp13 listening on /0.0.0.0:8009 Jun 17, 2004 11:53:00 AM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/32 config=C:\Tomcat5\conf\jk2.properties My worker properties files uses this..

Tomcat RPMs and database pools - no joy
Hi all, I have a war that connects to a database pool defined in a Resource section within server.xml. This war is run in a tomcat v5.0.19 environment as binary released by the jakarta project, and works 100%. I now want to deploy the war inside a jpackage RPM version of tomcat on my production server, and use the identical configurations for the Resource section and war, but an attempt to start the application fails like so: javax.servlet.ServletException: Error initialising za.co.fma.patricia.struts.PatriciaPlugin with configuration file at '/usr/share/tomcat5/webapps/patricia/WEB-INF/torque.properties': za.co.fma.patricia.PatriciaException: org.apache.torque.TorqueException: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver I tried the v5.0.24 RPM, and the same results were evident. Googling for the above shows lots of questions, but no definitive answers. Usually the problem goes away when the person with the problem goes over the config. In my case I know my config works, because my test environment is 100% functional. I am trying to work out what could be different between my test environment and the final tomcat RPM file. I have checked that the Postgresql driver is placed in common/lib in both the test environment and the RPM environment. In order for tomcat to install at all, I have forced it to ignore the following three dependancies, as (to my knowledge) they are are included in Sun's JDK v1.4.2 (and jpackage provides no compatibility packages to fake these dependancies for JDK v1.4.x): - [javamail].jar (is there already courtesy of Redhat supplied package, but jpackage cannot find it) - [jdbc-stdext].jar (part of v1.4.2, not present in Jakarta's official tomcat release) - [jndi].jar (part of v1.4.2, not present in Jakarta's official tomcat release) Has anybody got database pools and the tomcat5 RPM to work properly together, and was there anything you needed to do over and above the normal Resource configuration? The config for server.xml looks like this: !-- Global JNDI resources -- GlobalNamingResources Resource name=jdbc/GlobalPatricia auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/GlobalPatricia parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter parameter namedriverClassName/name valueorg.postgresql.Driver/value /parameter parameter nameurl/name valuejdbc:postgresql://127.0.0.1:5432/patricia/value /parameter parameter nameusername/name valuexxx/value /parameter parameter namepassword/name valuexxx/value /parameter parameter namemaxActive/name value20/value /parameter parameter namemaxIdle/name value10/value /parameter parameter namemaxWait/name value-1/value /parameter /ResourceParams /GlobalNamingResources The config for warfile.xml looks like this: Context path=/patricia docBase=patricia Valve className=org.apache.catalina.valves.RemoteAddrValve allow=127.0.0.1/ Logger className=org.apache.catalina.logger.FileLogger prefix=localhost_patricia_log. suffix=.txt timestamp=true/ ResourceLink name=jdbc/GlobalPatricia global=jdbc/GlobalPatricia type=javax.sql.DataSource/ Realm className=org.apache.catalina.realm.DataSourceRealm debug=0 dataSourceName=jdbc/GlobalPatricia userTable=person userNameCol=uid userCredCol=user_password userRoleTable=company_person roleNameCol=serial/ /Context Can anyone shed some light?

RE: question
Did you set up the web.xml file in your application area to direct the browser to your application? If you are using a servlet, then you should have something like the following in the web.xml file in your application's WEB-INF directory. ?xml version=1.0 encoding=ISO-8859-1? !-- This xml doc is for configuration of my web app -- !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app display-nameMy display name for Tomcat Manager/display-name description Some sort of description /description !-- Define your servlets that are included your application -- servlet servlet-nameMyServlet/servlet-name servlet-classmy.package.com.MyServlet/servlet-class /servlet servlet-mapping servlet-nameMyServlet/servlet-name url-pattern/servlet/MyServlet/url-pattern /servlet-mapping /web-app Now that that is set up, you may use the Tomcat administrator to add your app to the known contexts in Tomcat. After that has been done, try pointing your browse to http://localhost:8080/myapp/servlet/MyServlet and see what you get. Look at the servlet-examples tree for more detail and samples.

Tomcat 5 Database Connections
This is part question and part observation regarding database connectivity under Tomcat (5.0.24). My application normally runs in production at my company on a Tomcat 4.0.4 server. The applications includes Cocoon and access to several databases (Sybase) via both Tomcat connections from servlets and from Cocoon XSP pages. I've been at this for awhile now and I'm a huge fan of Tomcat (and Cocoon). On a new test server I setup Tomcat 5.0.24 and installed my applications. For sometime I thought all was well because most of my stuff is Cocoon driven, and it's fine, including database connectivity. This week I realized that my servlets are getting: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: null I've spent several days now trying to fix this. I've read verious posts from this list's archive, and several other places. I've studied many examples, and done google after google on it. My conclusion is that for whatever reason *a lot* of people have this trouble with TC 5x. However there are very few solutions. Yes, my jdbc jar file is in common/lib (and WEB-INF/lib, both). Yes, I've tried declarations in GlobalNamingResources and in the apps context, either. Yes web.xml contains a resource-ref with the same res-ref-name. The only thing I have not done is to create a META-INF/context.xml (is defining these resources in server.xml simply broken?). I'm dead stopped on this - yet I have no trouble at all with Tomcat 4.0.4. It seems like some people do get this to work. It seems like many, many people do not. Is there a bug at play in all this?

Sybase and Tomcat 5, Possible Problem
After a lot of effort, I feel there may be some reason that the Sybase JConnect JDBC driver doesn't work in Tomcat 5.0.24 (I use Tomcat 4 for my Sybase driven apps quite a bit). The exception is: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: null META-INF/context.xml is: Context path=/forteCommon docBase=forteCommon reloadable=true ResourceLink name=jdbc/odsdb03 global=jdbc/odsdb03 type=javax.sql.DataSource/ /Context From conf/server.xml contains: GlobalNamingResources Resource name=jdbc/odsdb03 auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/odsdb03 parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter parameter nameusername/name valueexcalibur/value /parameter parameter namepassword/name valuemypassword/value /parameter parameter namedriverClassName/name valuecom.sybase.jdbc2.jdbc.SybDriver/value /parameter parameter namedriverName/name valuejdbc:sybase:Tds:pdxax12:4100/value /parameter parameter nameurl/name valuejdbc:sybase:Tds:pdxax12:4100/value /parameter parameter namemaxActive/name value5/value /parameter /ResourceParams /GlobalNamingResources web.xml contains: web-app servlet servlet-name ProvCICS /servlet-name servlet-class com.ods.forte.cics.servlet.ProvCICS /servlet-class load-on-startup1/load-on-startup /servlet servlet-mapping servlet-nameProvCICS/servlet-name url-pattern/ProvCICS/url-pattern /servlet-mapping resource-ref descriptionodsdb03 Connection Pool/description res-ref-namejdbc/odsdb03/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref /web-app I have also tried working with the context placed in server.xml and with the Resource defined in the context, all combinations yield the same behavior. *Tomcat does actually log into the database server when it starts* I can see it from the database side. Therefore I know the jdbc jar file is loaded and the connection specification correct and working. In addition, the stack trace in catalina.out includes a point in Sybase code: Cannot create JDBC driver of class '' for connect URL 'null' java.lang.NullPointerException at com.sybase.jdbc2.jdbc.SybDriver.acceptsURL(SybDriver.java:197) at java.sql.DriverManager.getDriver(DriverManager.java:249) at org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:743) ... So can I conclude that the app is actually linked to the resource? If so then the problem seems to be that the information required somehow does not reach down the driver? Ideas?

Re: HttpClient
inbound.xml and outbound.xml are probably being written in JRUN and weblogic too, just not the same spot. inbound.xml and outbound.xml have nothing to do with tomcat. It must be some custom code. -Tim Malai wrote: Hi., In my web-application i'm communicating the other external server using thrier HttpClient Library.

Jasper2 fork
Greetings. Quick question re the jasper2 (org.apache.jasper.servlet.JspServlet) fork init param. The default of the fork setting is true, however the Tomcat 5 binary (and I think source) distribution ships with this init-param set to false. Now the reason I am curious about this shipping with this overridden to false is that I have innumerable memory problems - up until I was pointed in setting the fork init param to true. This *seems* to have solved pretty much all my problems! Is there some reason NOT to use this fork setting? Thanks a stack to those that assisted me! Very much appreciated!

tomcat5, apache2, mod_jk2 and mod_userdir
I don't seem to be able to get tomcat5, apache2, mod_jk2 and mod_userdir working together entirely. Everything works fine for the most part as users can serve jsp pages from their directories and tomcat recognizes each of their contexts. But I cannot get the uri host/~user/servlet/HelloWorld passed to tomcat with 2 wildcards (*). Here is an example of what the problem is using workers2.properties; If I try to do what I think should work; [uri:/~*/servlet/*] info=UserDir worker=ajp13:localhost:8009 It will not pass to tomcat and I recieve an apache 404 error instead of the servlet defined by the invoker (or a tomcat 404 error if the invoker didn't exist) If I try; [uri:/~user/servlet/*] info=UserDir worker=ajp13:localhost:8009 or [uri:/~*/servlet/HelloWorld] info=UserDir worker=ajp13:localhost:8009 It has no problem and everything works as it should, but it seems as thou it cannot deal with 2 wildcards if one is trailing the uri Anybody have any ideas or know what I am doing wrong? -RV - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I really like other things about the recent releases. But I have to agree. I just changed my java to call for a bogus resource name. The exception changed to no such resource in the context exactly as expected. So that's that. The server is connecting the database, and the app is looking up and finding the resource. But somehow the information needed to create the connection doesn't get through. Could there even be a work around?

Deploying problem with ant and the manager application
Hi
I'm trying to deploy a application using ANT but I don't get it to work.
I know that I'm doing som general error here, but since it's my first
build.xml script I just couldn't figure it out.
My install task looks something like this:
target name=list
description=List installed applications on servelet
container.
listurl=${manager.url}
username=${manager.username}
password=${manager.password}
/
/target
And I get the following error:
BUILD FAILED
file:/home/johan/development/javaxptest/build.xml:183:
java.io.FileNotFoundException:
jar:file:/home/johan/development/javaxptest/dist/xptest.war (No such
file or directory)
But my script have created a xptest.war file in the directory so I
don't know whats wrong.
Is it a permission error or what have I missed?
Please help

Tomcat 4.1.30 does not respect Date header
Hello. I am using Tomcat 4.1.30, with java 1.4.2 on a Readhat linux server. I was going to submit a bug report, but I noticed the bug tracker only goes through version 4.1.9. Is that bug tracker still being used? Should I still submit bugs to it? Anyway, I am implementing an HTTP Cache filter using the Java Servlet Filter API. The HTTP spec (ftp:/ftp://ftp.isi.edu/in-notes/rfc2616.txt) requires that a cached response set the Date response header to the date/time that the response was generated. In my servlet filter I accomplish this by calling: response.setDateHeader( Date, timestamp ); When I look at the actual HTTP generated response I'm finding that my attempt to set the Date header is being ignored and the date of the header always reflects the time now. So when my filter returns a cached response to the request, the Date header does not reflect the time the cached response was created and my code ends up violating the HTTP spec and breaks the manner in which the client should be calculating the freshness of the requested resource. This behavior is correct the majority of the time, however, there are cases, like this one, where the programmer needs to explicitly set the Date header. Do the developers agree with me that this is a bug, or am I wrong somewhere in my reasoning? Please let me know.

Classpath problems on Tomcat
From what I understand about Tomcat all of my application specific classes and libs are picked up after the bootstrap and system libs are grabbed. However, we are running into this problem: We have a package defined and several classes within this package. When we compile the source files they compile without problem (we set the classpath to WEB-INF/classes to make sure everything is picked up). However, at run-time, we get a NoClassDefFoundError on some of the classes package (but not all). The directory structure I have is as follows: WEB-INF / classes / search / dbBean / la / lib / ... (others, but not important) It is in the search package we are having this issue. Is there any other settings Tomcat needs to be able to correctly set the classpath to include these packages?

Re: JK2: lb_factor
I measured similar effects using The Grinder. Under maximum load with long running requests it can be even that worse that one Apache 2.x (default compile: prefork) with 2 Tomcats 5.x/mod_jk2 only distributes to the first Tomcat at all. This is true as long as Apache runs out of MaxClients because of the concurrent requests. Then, for some reason, Apache starts to distribute also some load to the second Apache. So it might help if you lower MaxClients (this seems the only thing that has an direct effect, not lb_factor, not ajp13 threads or anything else) to force this earlier, but be aware that this might produce errors if you get much more requests that then can't be queued anymore. I suppose Apache prefork and worker communication via shared memory by mod_jk2 don't work well together, or the don't work at all for true round robin. Putting more than 2 Tomcats won't help with high load. I once had 10 Tomcats, but in the end only the first few got most of the load, Tomcat No 7-10 almost nothing. I also heard that Apache MPM may help, but didn't try yet. So either I forget something in my config, I have to use MPM (although nothing is really mentioned about those issues in the docu), or mod_jk2 is really not too good in this area. Last advice: If you have that option to use a hardware router than I'd suggest to use more Apaches with only one Tomcat behind each of them. This will definitely work best as those routers do a true round robin. Ralph Einfeldt wrote: The quality of the distribution depends on the worker type of apache. (AFAIK only the 'worker' MPM will work) Nevertheless AFAIK the load balancing in mod_jk is not complete in this area, so I'm not shure if you will get the desired distribution (but it should be closer). -Original Message- From: Weseloh, Nicole [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 16, 2004 11:48 AM To: [EMAIL PROTECTED] Subject: JK2: lb_factor I've got a cluster with 2 tomcat 2.0.25 on different machines, on one of them also running Apache 2.0.49 with JK2 as a loadbalancer.

Tomcat 4.1 stops responding on RH9
Here goes Tomcat installaion on Red Hat Version 9 intermitnently stops Responding. I'm the Linux admin not the developer. The developer swears up and down its not his application causing the problem. In fact the same application runs on Red Hat version 8 without a problem. Using: Tomcat 4.1 j2sdk1.4.1 Red Hat 9 Kernel 2.4.20-9 It appears that tomcat was installed via RPM Version : 4.1.18 Vendor: JPackage Project Release : le.1jpp Can someone suggest how I can troubleshoot the problem. Right now, I have a perl script attempting to conncet to the tomcat server. If the server does not reposnd in 10 seconds it kiils the PID and restarts the server.

Connecting Tomcat and Apache
Evening all, I'm trying to connect Tomcat and Apache, I've been following this tutorial: http://www.meritonlinesystems.com/docs/apache_tomcat_redhat.html In order to run the buildconf.sh I installed libtool, httpd-devel, autoconf and automake because I found on a site that redhat 9 users need httpd-devel, the rest are dependencies.

basic authentication or not?
In a nutshell, I'm wondering if it's better NOT to use basic authentication. We have over 10,000 regular users, and I think it would be good for us to move to a more standard login page instead of that authentication box that pops up. My question is, would we have to change a lot to do this? At the moment, I'm not even sure we're using basic authentication, and below I will outline my attempt to determine if we're even using it... When you type the URL to our website, it pops up an authentication box before it shows you anything else and you must get past that to get into the web app. As far as I understand (the original developer is no longer with us), we are using basic authentication with Tomcat 4. However, I was perusing this document to figure out where our basic authentication is configured and it doesn't look like we have all this stuff: http://www.jguru.com/faq/view.jsp?EID=1131436 Notable exceptions are any security-constraint or login-config nodes in our web.xml, and since the example on the jguru page put BASIC in the login-config node, I'm really not sure that we're using basic authentication (although that's still my gut feeling). In our server.xml, I see that both of the following are uncommented, but I'm guessing that only the second one is being used since I don't think we have anything (no JNDI) set up for the first one: Realm className=org.apache.catalina.realm.UserDatabaseRealm debug=0 resourceName=UserDatabase / Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://127.0.0.1/mainDB connectionName=user connectionPassword=pass userTable=users userNameCol=Username userCredCol=Password userRoleTable=roles roleNameCol=Role / Aside the big database used by our web application, we have a small MySQL database whose sole purpose is to authenticate users. Would it be just as simple to continue using that for authentication if we moved away from this popup box authentication? Is there any good reason to have this authentication database outside of our main database? Or is this somehow protecting our web app more--making you authenticate before you ever communicate with anything in our site (e.g. a LoginServlet or something like that). I know this is long...I appreciate any feedback, though! Thanks, Stephen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

mod_jk is corrupting chunked responses
i've developed a servlet that streams data back to an applet using transfer-encoding=chunked. everything works fine when the applet connects directly to tomcat. but when it connects via apache/jk2, the streams is corrupted. the servlet sets the headers like this... httpServletResponse.setHeader(Pragma, no-cache); httpServletResponse.setHeader(Cache-Control, no-cache); httpServletResponse.setDateHeader(Expires, -1); httpServletResponse.setHeader(Content-Length, null); httpServletResponse.setHeader(Connection, close); httpServletResponse.setHeader(Transfer-Encoding, chunked); the response outputstream is wrapped... bufferedOutputStream = new BufferedOutputStream(outputStream); chunkedOutputStream = new ChunkedOutputStream(new DataOutputStream(bufferedOutputStream)); dataOutputStream = new DataOutputStream(chunkedOutputStream); it seems the problem is that mod_jk is stripping the chunking headers, which includes the size of the chunk followed by \r\n. does anyone know a work around for this? please help. -ming fang - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: basic authentication or not?
Duh. I was looking in the general Tomcat web.xml--yes, in my app-specific one, we're using BASIC authentication. Ok, so Tomcat knows to use the additional MySQL database for authentication. Right now, if you go to www.ourDomain.com it'll make you authenticate and then it will forward you to the default web application at www.ourDomain.com/DefaultApp/Welcome.jsp, and we have several web apps and you can cross from one to the other without authenticating, so you could go up and modify the URL to www.ourDomain.com/OtherApp/index.jsp and you'd be there instantly. So my question is, if we changed to form-based authentication so we could present our look and feel from the start, would it work for authenticating all the web apps if the login page was under a particular web app's folder? In other words, where would and could we stick a Login.jsp that would be presented to the user when you type www.ourDomain.com?

Multiple Thread Pools
Is it possible in tomcat to segregate certain jsp pages to its own thread pool/connector? We have certain pages that take a while to execute, and when multiple users access the page, all threads are used up serving those requests. Weblogic allows defining multiple ExecuteQueues and assigning jsp /servlets to this queue -- you can either throttle bad pages or ensure thread availability for critical pages. Is there a way in tomcat to achieve similar results? Or are my options limited to 1.increase the maxThreads count 2.try and improve the performance of those pages 3.implement a poll/callback on the long running page to prevent tying the thread up.

Object datasource =

But if I run it as a tomcat user, then no mod_jk.conf file is created. 3) But not least, I would like to web applications through my user directories and not through the tomcat directory.

RE: three problems
Thanks for your prompt answer, Could you be more specific on the address attr? I have the following in the Connector element on my server.xml: Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8080 minProcessors=5 masProcessors=75 enableLookups=true redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 useURIValidationHack=false disableUploadTimeout=true / -Original Message- From: QM [mailto:[EMAIL PROTECTED] Sent: Thursday, June 17, 2004 6:09 PM To: Tomcat Users List Subject: Re: three problems On Thu, Jun 17, 2004 at 05:44:51PM -0600, Casas, Claudia wrote: : 1) When I go to another PC and try to access my server: : http://my.domain.com:8080 http://my.domain.com:8080/ I get The page : cannot be displayed : but if I access http://my.domain.com:80 http://my.domain.com/ : (apache), it works fine : : Why in this world can I access my tomcat from my server directly but not : from outside my server??

I see the address attr isn't being used, so Tomcat should be listening on all available IPs. For sanity's sake, please confirm that Tomcat's running: lsof -i :8080 If that returns data, then it's down to a networking issue. Is there a firewall between the other computer and the Tomcat machine?
