TAG Lib problem

[Pablo Carretero Sánchez]

Hi all,

I have a problem with the Jasper compiler when I try to compile a JSP using
TagLibs.

The configuration is:

Tomcat 5.0.19, JSDK 1.4.2.

I have a simple application with:

.- 1 TLD:


Operacion
com.kutxa.kn.comun.tags.TituloOperacionTag

MasInfo
false


Titulo
false
true


Ancho
false
true


Salto
false


VolverInicio
false
true






JSP:  With on reference to the TLD:
   


JAVA TAG CLASS: With one attribute and method:
   - String Titulo
   - public void setTitulo(...){
 }
   - public String getTitulo(...){
 }


When the jasper compile the JSP I have one error:

"...Unable to find setter method for attribute"


org.apache.jasper.JasperException: /jkn_opkn/tmpl/es/posglobal.jsp(433,0)
Unable to find setter method for attribute: Titulo

AIX 4.3 - java 1.3.0 and Tomcat 4.1.30

Hi there,

Trying to launch Tomcat 4.1.30 on an AIX machine ( version 4.3 ) with the java 1.3.0 
build from IBM.

However it gives me this error:

[ERROR] Digester - -Begin event threw exception java.util.MissingResourceException: Can't find bundle for base name 
org.apache.coyote.tomcat4.LocalStrings, locale en_GB

 

Anyone had this problem? Its really strange. Tried having all libraries and jar files 
in the classpath.  Also tried clearing out the classpath, still no luck.  At this 
point upgrading java is not the best option as other applications running require it.

Any ideas?

Many thanks in advance.

Andy Morton

 

TC4.1.30 autoDeply ignored?

[Lemke, Michael IZ/HZA-IOR]

I am trying to configure TC4.1.30 according to my needs.  When I set

 
  

in conf/server.xml Tomcat nevertheless deploys every directory under
webapps.  The only effect I can generate with that line is to 
ignore the .xml files in webapps.  What am I missing here?

What I want eventually is to ignore directories, honor .xml files
and unpack .war files.

Thanks,
Michael

problem with JNDI realm

[Sebastien Brunot]

Hy,

 

I've got a problem with JNDIRealm : the group a user is in in my LDAP
directory is an object which attribute "member" contains the user CN. So
I've set up the roleSearch attribute of JNDIRealm to the value
"(member=*{0}*)".

 

Both wildcards are replaced with the "\2a" String by JNDIRealm before
running the search  and the group my user is in is never retrieved. My
interpretation of RFC 2254 is that those wildcards shouldn't be replaced
with "\2a" : the replacement should only occur for wildcards in the String
that will replace the {0} portion of the filter, aka wildcards in the user
CN.

 

Is there an existing patch for this problem ?

 

Sebastien

Filesystem Layout

[Thomas Zehetbauer]

Hi,

to ease upgrading I am using $CATALINA_BASE to separate my local
configuration from the tomcat installation. Now I am trying to configure
a J2EE JNDI datasource and have found that: "These jar files along with
your the jar file for your JDBC driver should be installed in
$CATALINA_HOME/common/lib.".

I hope there already is an undocumented way to install additional JAR
files in $CATALINA_BASE but if there is none, I guess this would be an
useful feature to add.

RE: Weird stylesheet behavior

[Jérôme Duval]

Well I just unistalled 5.0.24 and installed the 5.0.27 binary version. The
stylesheet works correctly. I guess I'll try rebuilding the code or
rebuilding Tomcat.

I developped a webapp in Windows XP using Tomcat 5.0.24 (the binary
download). Everything is swell on my machine. When I copied it to a linux
box (using Fedora 2), on which we installed Tomcat 5.0.27 from source, my
application works, but the stylesheet stuff doesn't show at all. Inline
definitions also don't seem to matter. I am checking the application from IE
on another computer and the source contains all the necessary info (ie.

RE: SunONE versus Tomcat performance

[Jérôme Duval]

Why would you compare Apache and Tomcat vs. SunONE? Isn't there a lot of
overhead in using the connector and all that? Seems to me a more logical
test would be Tomcat vs SunONE and the most recent version of both, which
Tomcat 4.1.30 is not. I smell bogus test results!

I used it for webservice before, and it is faster than Tomcat, but I
wouldn't say that was 2 to 5 times for that particular case.  You can get it
for free because it's bundled with the Application Server platform which is
free.

Please see the download page from tomcat.
Tomcat is written in java, so the windows distribution works in linux too. There are 
different shell scripts to run for each platform.

Re: web.xml: my default.css file does not work correctly

[Jon Doe]

Thanks for this. But it still didn't answer my problem (which is solved -- 
see below). I don't have a 'welcome file'. I have a welcome page generated 
by a servlet -- so you can reference it with

  http://localhost:8080/context/home.myext
And I can map this no problem. But to get this to work:
  http://localhost:8080/context/
fails. I assumed the '' was relevant, but it only seems 
to be for real files (html, jsp, etc), not for 'virtual' URLs.

But for the record I solved my problem by creating an index.html file with 
just:

  
and had *everything* else mapped using my Router servlet. Works like a 
dream!

Thanks again.
Joe.
: So, I've disabled the / mapping by commenting it out. And my CSS
: pages are working as normal. But trying to access my app with the root 
URL
: just causes a directory listing.

Check your book (or the servlet spec) for "."
It's akin to the "DirectoryIndex" directive in Apache httpd, which lists
the file(s) checked when a request is made to just a directory path
(e.g. index.html).

RE: concurrency management

[Shapira, Yoav]

Hi,
If two users are on the app at the same time, both accessing the
database at the same time, and both have write privileges to the same
data, you are responsible for synchronization to suit your goals.  This
might mean no sync at all, meaning a simple race.  That's not
necessarily a bad thing, it depends on your app.  Many people think a
race condition is always a bad thing, and it's not.

If your application requires transactions, you will need to download the
JTA (you can get it by itself from java.sun.com, don't download the
whole J2EE jar) and an implementation thereof, e.g. Tyrex or JOTM, and
code your app to use it.  You can do this within Tomcat without going to
JBoss or another full-fledged J2EE server.  However, again depending on
your sync requirements and surrounding architecture, you might want to
get a full J2EE server which would have JTA support built-in.

BTW, JOTM is an excellent product, we use in production and like it.

Say what?  That's not what I said or at least not what I meant ;)  A
ServletContextListener is good.  A  servlet is also
good, but for other things, as the container may restart it at will.
Using one does not preclude using the other.  For your scenario, I think
the Listener is a better choice than the servlet.

RE: Is it possible to modify request parameter?

[Shapira, Yoav]

Hi,
Yes.  Use the HttpServletRequestWrapper, and modify the
getParameter/getAttribute/getHeader/getQueryString methods as you need.
You will need a Filter to go along with this, mapped to /servlet2 in
your example, which will intercept the request and wrap it with your
wrapper.

RE: Jakarta Commons Configuration files

[Shapira, Yoav]

Hi,
There hasn't been a release of commons-configuration yet (ever).
Version 1.0 is coming fairly soon, but then again that's been the status
for a while and I won't get into a rant about scope creep...  How have
you come to rely on it?  That's strange.

If you need them, you have to download the code from CVS and build it
yourself (it has a build script of course).  I was going to suggest the
nightly Gump builds for it
(http://brutus.apache.org/gump/public/jakarta-commons/commons-configurat
ion/index.html) but I see that it failed last night so that's a no-go.
Anyways, I don't think you should depend on it.

By using UserTransaction class I can get the control on transaction

But what if we are having  two different tomcat server with two

In this type of situation what to be done, since the other server is not

Re: concurrency management

[Filip Hanik - Dev]

if the backend database is the same, that DB will handle your transactions according 
to your transaction level.
if you want to handle the transactions by JTA/JTS then you need a system that 
implements distributed transactions, and that will not
have a pleasant effect on your performance :)

RE: other ways to register a Servlet web application

[Shapira, Yoav]

Hi,
I'll get you started, in my email editor and without even trying to
compile this out of laziness:  (But it should be very close)

import org.apache.catalina.Context;
import org.apache.catalina.Engine;
import org.apache.catalina.Host;
import org.apache.catalina.Server;
import org.apache.catalina.ServerFactory;
import org.apache.catalina.Service;
import org.apache.catalina.Wrapper;

public class NotPortable {
  public static void addServlet(Class myServletClass, String urlPattern)
{
Server server = ServerFactory.getServer();
Service service = server.findServices()[0];
Engine engine = (Engine) service.getContainer();
Host host = (Host) engine.findChildren()[0];
Context context = (Context) host.findChild("mywebapp");
Wrapper wrapper = context.createWrapper();
wrapper.setServletClass(myServletClass);
wrapper.addMapping(urlPattern);
wrapper.load();
context.addChild(wrapper);
// Optionally context.addServletMapping
}

A production-quality implementation would not hard-code the name of the
webapp, nor would it hard-code the 1st service and 1st host (index [0]
in the above code).  It might also pass init parameters, etc, but this
just an example to give you an idea.

yes, that helps.  Then it doesn't deploy anything.  Unfortunately,
still not what I want:

I can't have .xml deployed but directories not.  Only the other

Re: SunONE versus Tomcat performance

[Vy Ho]

I am sorry for not being clear enough.
The test did not run with both Apache and Tomcat, only Tomcat 5.0.  
Please understand that I do not try to create a flame war here.  This is 
only a particular case, no scientific comparison, and no pointing out 
which one is better overall.  Please download it yourself, and try with 
your application if performance is something you want to find out.

Jérôme Duval wrote:
Why would you compare Apache and Tomcat vs. SunONE? Isn't there a lot of
overhead in using the connector and all that? Seems to me a more logical
test would be Tomcat vs SunONE and the most recent version of both, which
Tomcat 4.1.30 is not. I smell bogus test results!

I used it for webservice before, and it is faster than Tomcat, but I
wouldn't say that was 2 to 5 times for that particular case.  You can get it
for free because it's bundled with the Application Server platform which is
free.

The link to the KeyLabs report is at

Why would SunONE be anywhere from 2 to 5 times faster than Tomcat?
They also suggest that Tomcat would start to show errors when 
loading 200 users at a time, whereas SunONE could handle up to 500 
users without any errors.
   

It's hard to say why the Apache/Tomcat combination would not perform 
as well as SunONE (which I am not familar with), but without more 
details of the Apache/Tomcat configuration it's too difficult to say.

Has anyone independantly tested SunONE compared to Apache/Tomcat?

Hi,
You might be right.  I've been away from TC 4.1 for too long to say
definitively...

RE: SunONE versus Tomcat performance

[Jérôme Duval]

The report you linked to ran with Apache and Tomcat version 4.1.30. Don't
believe me?
3.2 Web Server Configuration

3.2.1 Apache /Tomcat
For this test KeyLabs used Apache 2 and Tomcat 4.1.24. The Apache web server
was configured with
the Coyote connector. During the test all request were directed to the
Apache web server, which then
routed only the JSP requests to Tomcat. When the Apache server was compiled
SSL enabled, and the
worker mpm was specified. Tomcat used the Sun Java version 1.4.1_03.

In any case, I am just saying that the test results appear bogus to me,
because I would use only Tomcat as a web server (for both dynamic and static
content). That being said, SunONE might be better then Tomcat, but I don't
know because I haven't seen a reliable comparison and haven't tested them
myself.

Cheers!

Why would SunONE be anywhere from 2 to 5 times faster than Tomcat?

They also suggest that Tomcat would start to show errors when 
loading 200 users at a time, whereas SunONE could handle up to 500 
users without any errors.

Hi, i use tomcat 4.1.30 with apache 1.3.31 but i have some problem using the

when i start tomcat all is fine but when one of the site change his

apache (only on tomcat) for them to work i need to restart java completely
each time, i think this come from a problem of configuration of mod_jk but i

Do some searching in the archives.  Myself and others have talked about 
this to people at different times.  Try running tomcat not as a service,

but as a standalone application and you'll find that it will work for 
you, so it deals with a security setting some where on your computer.  I

assume this is on a 2000/XP machine.  You may have to give access to 
some registry entries to the user the service is running as for this to 
work properly.  Anyways, it's a security issue in one way or another or 
it's a path related issue (the user the service is running as doesn't 
have all the paths needed for some native libs or something).  Try 
adding the user the service is running as to all the directories under 
tomcat recursively, possibly some registry entries, and possibly some 
dll's for the access database drivers.

If you're using the mod_jk.conf auto-generation (I assume you are from 
the context of your message), then its simply because the mod_jk module 
only generates that file when Tomcat is started, once started, that file 
is not modified again. Even so, as far as I know, Apache doesn't pick up 
modifications to its .conf files - so Apache would need to get restarted 
for the updated configuration to take effect.

The same would be the case if you weren't running the auto-generation, 
you would need to add the JKMount directives to your apache 
configuration manually, and restart Apache for the changes to take effect.

Or maybe I've misunderstood your problem?

Re: SunONE versus Tomcat performance

[Robert Bateman]

I've just finished reading the report and can find no where in the report that 
Tomcat failed

It *does* indicate that the combination of Apache httpd and Apache Tomcat had 
problems - but the report does not indicate, as far as I can tell, which 
component reported the failure.  Without knowing "where" the error came from 
and what the error was - it's impossible to determine if httpd or Tomcat was 
the source of the error.

I wish the report would have detailed the configurations of all 3 tests as 
well as some of the errors that were received and where the error came from.  
That way we could more easily identify what the failing component was.


Just my opinion though.

You may be having a problem with the case of your tag attribute. Try 
changing the case of the attribute to all lower-case: "titulo" and see 
if that helps.

AW: Connecting to MS Access DB

[Gunnar Pörschke]

I think you need to run tomcat with an account that is allowed to access
network connections.
Could you please compare local security policy and compare local rights
assignment between system and the other user account.
Check if system is allowed to interact with desktop if you start the service
with system (see local services).

Cheers,

Do some searching in the archives.  Myself and others have talked about 
this to people at different times.  Try running tomcat not as a service,

but as a standalone application and you'll find that it will work for 
you, so it deals with a security setting some where on your computer.  I

assume this is on a 2000/XP machine.  You may have to give access to 
some registry entries to the user the service is running as for this to 
work properly.  Anyways, it's a security issue in one way or another or 
it's a path related issue (the user the service is running as doesn't 
have all the paths needed for some native libs or something).  Try 
adding the user the service is running as to all the directories under 
tomcat recursively, possibly some registry entries, and possibly some 
dll's for the access database drivers.

Re: [tomcat] proxy to php app

[Ruth, Brice]

This is also what we do. http://www.fiskars.com/ is a Struts/Tiles/JSP 
web-application, http://www.gerberblades.com/ is a PHP application, both 
run through the same server, Apache+Tomcat. We're not using JK2, we're 
using the original JK, but either way - if you setup Apache+JK(2), then 
you can have your cake & eat it, too. You can even mix 'em in the same 
VirtualHost, if you want ... just use Apache's mod_rewrite rules to 
ensure that everything goes smoothly, if needed.

I've started to use apache with mod_jk2, meaning that apache handles the web

In that way you keep using all your apache "goodies", cgi-bin, php, etc...
So my recommendation is: use mod_jk2, keep apache for everything else...

Weaver Release Announcement (XML Programmed Servlet Controller Component)

[Paul Harvey]

Weaver is a pure-Java, XML programmed Controller component for 
developing Model View Controller (MVC) structured, servlet based, Web 
applications.

Weaver exploits your existing knowledge of the JSP Expression Language 
(EL) and of JSTL via a consistent XML tag set.

The main features of Weaver include:
* Programmed via a simple but powerful XML syntax whose elements 
are modeled after those provided by JSTL.
* Support for an Expression Language (EL) syntax that is identical 
to that of JSP 2.0.
* Easily extensible XML tag vocabulary.
* Support for JSPs and for other View technologies.
* Model functionality is easily added via the implementation of a 
simple Java interface.
* Provision for multiple cooperating applications.
* Transparent support for authentication.
* Provides a management console to monitor and to configure running 
applications.
* Runs in any suitable servlet container.
* Automatic application reloading for rapid development.
* It's Fast!

Weaver's home page may be found at: http://www.oldlight.com/weaver/
Weaver may be downloaded from: http://www.oldlight.com/weaver/downloads.html

Re: Connecting to MS Access DB

[Robert Bateman]

Khalid,

Search the list...  You will see that Windows 2000/2003/XP services need to 
know how to "log into" any data bases in order to access them.  One of the 
biggest problems with services is accessing "mapped" files or files that 
require "user permissions."  It is unfortunate, but a fact of life on Windows 
2000/2003 and XP.

Just a thought...  Can you use the "personal" version of SQL Server 2000/2003 
instead of Access?  I believe Tomcat service will access this just fine.  
Same with MySQL and Postgres SQL.

Re: horrible problems with TC4.1 under RedHat Advanced Server

[Ruth, Brice]

Well, first off, it appears your problem is related to your JDK, not so 
much Tomcat - I'm sure you've assumed as much. Have you tried grabbing 
other JDKs? You seem to be using Sun's JDK (which happens to be running 
smoothly on two RedHat ES 2.1 systems I have, no modifications were 
necessary to install, either). BEA has a free (right? I think so ..) JDK 
called JRockit, which also runs smoothly on RedHat ES 2.1 (one server 
here with that). Then, of course, you can grab IBM's JDKs - they have 
all sorts of different flavors, but I know that on one RedHat ES 2.1 box 
hosted externally with Rackspace, IBM's JDK was installed by default ... 
so I imagine there's some history there.

Give a few different JDKs a whirl and see if your problems go away!!
Good luck.

(The move is for support reasons.)
Things were working basically okay under Red Hat 9.
But under Advanced Server or Enterprise Server, I have these two
problems:
1. Some pretty high percentage of the time, Tomcat fails to
  start.  After invoking "catalina.sh start", I get the errors
Another exception has been detected while we were handling last error.
Dumping information about last error:
ERROR REPORT FILE = (N/A)
PC= 0x
SIGNAL= 11
FUNCTION NAME = (N/A)
OFFSET= 0x
LIBRARY NAME  = (N/A)
  Simply retrying the command usually works, although sometimes
  it takes three tries.
2. Much more seriously, my web apps have been mysteriously hanging.
  They don't tend to crash or burn or emit error messages, they
  just... stop... responding.  In one case (that is, for one of
  my applications) they seem to hang after acquiring and holding
  certain database resources, which ends up meaning that other
  applications running on other servers also accessing that
  database also hang.
  In some cases these hangs are accompanied by the messages
org.apache.tomcat.util.threads.ThreadPool logFull
SEVERE: All threads (75) are currently busy, waiting.
Increase maxThreads (75) or check the servlet status
  I increased maxThreads (and maxProcessors, since the
  documentation is inconsistent) to 200, but now I just get
  "All threads (200) are currently busy, waiting".  Furthermore,
  it's not clear whether this thread exhaustion is the primary
  cause of my problems, or just one of the symptoms.
I suspect that there's some pernicious incompatibility between
this version of Tomcat, this version of j2sdk, and the C
libraries in these releases of RedHat.  (When I built these
machines, I think I had to manually install a C compatibility
library to get Java to work at all.)
There was a message to this list a month or so ago from
Harald Henkel describing some similar-sounding problems, but
it doesn't look like he got an answer.  He mentioned setting
LD_ASSUME_KERNEL to 2.4.1, and I'm going to try this, but it

his problem.
Anybody got any ideas?  Has this sort of thing happened before?
(Web searches haven't really turned up anything.)
Is there something I'm missing?
Here are the exact details of what I'm running:
Jakarta Tomcat 4.1.30
j2sdk 1.4.2_04
Working system:
Red Hat Linux release 9 (Shrike)
kernel 2.4.20-8smp
Troublesome systems:
Red Hat Enterprise Linux ES release 3 (Taroon)

Re: horrible problems with TC4.1 under RedHat Advanced Server

[Ruth, Brice]

Just as an FYI - with Sun's JVM, on Redhat ES 2.1 systems, I've seen no 
problems ... we've been running a production system which averages about 
57K visitors, 768K page views a month - on Tomcat 4.1.27 and Sun's 1.4.2 
JDK (RPM install).

This is running a slightly modified Rackspace kernel derivative of 2.4.9.
Chong Yu Meng wrote:
I think RHAS is running NPTL.
If you're using IBM's Java 1.4, 1.3.x or earlier and RH9, RHEL, RHAS , 
you need to set LD_ASSUME_KERNEL=2.2.5.
If you're using IBM's Java 1.4.1 or better on RH9, RHEL (not sure 
about RHAS), you don't need to set LD_ASSUME_KERNEL at all
If you're using IBM's Java 1.4.1 or better on Fedora Core 2, you 
definitely need to upgrade your kernel version to 2.6.6-1 or better. 
Though, if you're using the latest 2.6.6-1.435.2.3, you may get some 
strange problems if you're running on a Thinkpad, so use the earlier 
2.6.6-1.435 (if you can do without the security update).

I have not used Sun's Java on Red Hat systems, so I cannot say what 
will happen.

I have used Blackdown's 1.4.1, compiled with gcc 3.2 on FC2 and they 
work fine, even on the stock install kernel (though freezes can still 
happen). Although benchmarks (Volano Report) show Blackdown to be 
slower and possibly less scalable, I find that it performs on a wider 
range of Linux platforms.

I find the following procedure helps me to identify the problem:
After installing Java on your system, just execute "java -version". If 
you get a segmentation fault, you should try setting LD_ASSUME_KERNEL 
to 2.2.5, then 2.4.1. 2.2.5 bypasses the NPTL. See which setting works 
for you.

If you don't get a segmentation fault, try running the SwingSet2 
application which should come with your Java distribution. On FC2's 
stock kernel, this can freeze your desktop so bad that you'll need to 
power down your system manually. Upgrade to the latest (or next to 
latest kernel) and you should be fine.

There may be other problems I'm not aware of. Please post them here. 
I'm especially interested in hearing from people using the Sun JVM.

pascal chong

It's definitely some sort of JVM/OS issue, and not directly related to
Tomcat.  What glibc version are you running, are you running all errata
for the system (up2date)?  Also upgarde to the latest JDK, and finally,
if it is still not stable, try a LD_ASSUME_KERNEL setting of 2.2.5.

Host Aliases, Wildcards

Hey all.
I've searched the internet about this, but have come up empty handed, 
so I'll ask you guys;

Is it at all possible to use wildcards in host aliases? I have a host, 
say example.com. I would like all requests to anything.example.com to 
alias to example.com. I've already set up the DNS server to resolve 
hosts accordingly.

Weird context.xml default application problem

[Keith Bottner]

This is strange!

When I package my application and deploy it my context.xml file that is
contained within the META-INF directory is copied to the
CATALINA_BASE/conf/Catalina/localhost/app.xml properly.  Here is the file
for reference:






My server does NOT recognize this as the default web application, instead it
lists the directory contents for the webapps directory. BUT, and here is the
weird part. If I manually edit the file and add or remove a line and restart
appropriately, it then does get recognized as the default application. Any
ideas? Or am I just getting lucky that it ever gets recognized as the
default app and I should be setting this directly in server.xml? And how
does the default install of tomcat always seem to recognize ROOT as the
default even though there is no settings in server.xml or a context.xml file
associated with it?

Thanks in advance for any help,

Keith

Hrmpf, that is strange ... JK (to my knowledge) does no caching, so 
every request that matches its JKMount map parameters is handed off to 
Tomcat. When you change a .class file, reload the application, and 
access it via Tomcat directly (port 8080?) - your changes appear? But 
not through Apache?

Re: TAG Lib problem

[Ruth, Brice]

Pablo,
No, I'm afraid I don't know of any other workaround. This is all part of 
the tag spec, I believe, so it has to be done "right" ... I can only 
assume that BEA was lax in this regard ... but since Tomcat is the 
reference implementation, I'd expect it to adhere pretty closely to the 
specification.

That's all I can provide - maybe someone else has an idea for you!

the attribute in the tld, I need change the attribute in all my jsp, that is
very power change.
I appreciate your info, but do you know any other work around.
Thank a lot.

Re: [tomcat] proxy to php app

[Ruth, Brice]

Well, Tomcat can't load PHPs, so what server are you using to server the 
PHP content? Why does Tomcat have to be the proxy, instead of the other 
way around? Writing a proxy servlet sounds like its going to be painful ...

In that way you keep using all your apache "goodies", cgi-bin, php,

So my recommendation is: use mod_jk2, keep apache for everything else...

Re: Host Aliases, Wildcards

[Ruth, Brice]

Well, you should be able to use the mod_jk (or mod_jk2) module to hand 
off request to any JSPs to Tomcat ... and Tomcat can just be configured 
under a single host, so what the incoming hostname request looks like 
won't matter to it ... only the context its requesting.

Have you configured Apache to talk with Tomcat via JK?

Re: Weird context.xml default application problem

[Ruth, Brice]

I've heard mentioned that in the Tomcat codebase, "ROOT" is treated as a 
special identifier.

As for your problem ... I believe that Tomcat does not support 
deployment of the default context from the META-INF directory of your 
web-app. You need to explicitly configure it from server.xml or from the 
conf/Catalina/localhost directory. What you've seen is essentially that 
... it will automatically put it in the proper directory, but it will 
stop short of configuring the default context for you.

Keith Bottner wrote:
This is strange!
When I package my application and deploy it my context.xml file that is

My server does NOT recognize this as the default web application, instead it
lists the directory contents for the webapps directory. BUT, and here is the
weird part. If I manually edit the file and add or remove a line and restart
appropriately, it then does get recognized as the default application. Any
ideas? Or am I just getting lucky that it ever gets recognized as the
default app and I should be setting this directly in server.xml? And how
does the default install of tomcat always seem to recognize ROOT as the
default even though there is no settings in server.xml or a context.xml file
associated with it?

RE: Multiple contexts mapped to single docbase

[Robert Hunt]

Re: multiple mappings; not exactly the point and I apologize for not
specifying that 'docBase="appXyz"' (in both  descriptors) should
be an absolute reference.

The point was to have multiple contexts mapped to the same docbase, BUT,
with each context having its OWN web.xml deployment descriptor.

Using the undocumented (you don't see it listed in most texts) defaultWebXml
"feature" achieves this purpose.  But, as it is "undocumented," I'm
wondering if there's a better/more-robust (read: supported) method.

Re: Host Aliases, Wildcards

[J . Lindberg]

Yes it's configured to forward requests to tomcat, [uri:*.jsp]. The  
thing is, I have several virtual hosts on the server and I would like  
to keep them separate. I have had some issues using just one host on  
tomcat, namely; if you have two domain names and they both have a JSP  
page called page.jsp, then whichever domain who compiles this page  
first will have the other domain use the same compiled servlet!

I have used the host alias directive as found in the tomcat  
administration interface, it works superb on FQDN's, I just wish it  
would work as good using wildcards!

Tomcat docs on host aliases say nothing about wildcards, so I'm  
assuming it's not implemented. Would be nice to see a change in this  
policy. :)

How to deploy customized realm, authenticator, etc.?

[Dennis Dai]

In my webapp, I have customized realm and authenticator. I was wondering
how they can be easily deployed. Since they're internal to tomcat,
they'll need to be put into server/lib (or server/classes), thus can't
be put in the WAR file, which means the deployment won't be as simple as
dropping the WAR file into webapps directory.
Sure I can put the jar into server/lib, but those really belong to my
webapp (ie. not used anywhere else) and I'd really like it to go with my 
webapp.

Any ideas? Thanks.

ISAPI and SSI w/ IIS

[George Sexton]

I have been playing with trying to server side include a URL that is in a
context handled by the ISAPI redirector. This is on Windows Server 2003 with
isapi_redirector2.dll version 2.0.4. The chain is something like this:

URL /calendar/OutputCurrentWeek.html is in a context handled by the ISAPI
Filter. Directly invoking this URL produces output.

Attempting to invoke the URL via SSI as shown below fails:



I'm pretty sure that what is happening is the SSI handler is not passing the
request through the ISAPI filter chain.

I also tried something like:


And


The last two trys generated 500 errors.

Does anyone have any ideas on how I can do a server side include to a
context URL?

As a fallback, I can use some code to invoke the URL using a
Microsoft.XMLHTTP control, and retrieving the body text.

Any ideas are appreciated.

Re: How to deploy customized realm, authenticator, etc.?

Thanks Yoav.
I'd like it to be as simple as dropping a WAR file into webapps 
directory. But in my case, I'll have to drop something else into either 
common/lib or server/lib if not using a customized ClassLoader, right?

Also, putting them into common/lib didn't seem to work because my 
customized realm, authenticator use classes from Catalina, which is not 
available at common ClassLoader level.

If I'm going to use customized ClassLoader, how am I going to do it? I 
mean, if I do it on the Catalina side, that means some customized stuff 
needs to go into common or server, right? And I'd assume I can't use 
ClassLoader on the webapp side to load customized realm and 
authenticator, can I?

Sorry I'm not too familiar with ClassLoader stuff ...

Re: How can I display number of requests over the past n seconds?

[Justin Ruthenbeck]

More academic exercise than recommendation, but...
Write your own implementation of a Map/HashMap
specific to java.util.Date objects.
Identify your smallest time increment (5 seconds in your email).
Identify largest time increment (60 seconds)
Create (60/5)+1 buckets for your hash function
Write your hash function such that each date object -- representing one 
request each -- gets placed in the right bucket.  If the bucket contains 
"aged" dates, which you should know by simple counting (not comparison), 
empty it before placing a new one in.

To display results, simply add up the content size of the appropriate 
buckets and return.

This implementation is more lightweight than others suggested because the 
process of pruning is built into your implementation (instead of using 
external threads or comparisons each time you insert)... you're trading 
memory usage for decreased processing time.  On the other hand, it 
doesn't *strictly* tell you how many requests came in the last X seconds 
-- only how many came since the last time unit started.  It's also only 
reasonable for numbers like you suggested -- Tim or Yoav's suggestions 
would be better if your range is 5 seconds to 60 minutes, for example.

Hi,
Is the driver in the common/lib directory?

JK2: Override uri:vhost.tld/* mapping?

[Thomas Zehetbauer]

Hi,

is it possible to override a [uri:vhost.tld/*] mapping from
workers2.properties in httpd.conf? Or add a negative uri mapping to
workers2.properties? I want most requests to be dispatched to Tomcat but
I also want to have e.g. /~user to be handled by Apache.

Tom

Re: javax.servlet.ServletException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver

[David Smith]

Hi Isen.
This is a common problem and usually means your JNDI naming is 
inconsistent or your missing config info in one or more of the following 
files:

server.xml ( if you defined your JDBC resource here )
[context].xml
web.xml
Java code
Essentially make sure there are no spelling/capitalization mistakes and 
all the necessary parts are there, including the JDBC driver jar file in 
the common/lib directory.  The JNDI howtos on the Jakarta site is a good 
place to look:

(these are for tomcat 5, there should be equivalents for tomcat 4)
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-resources-howto.html
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html
If you're still running into brick walls, post appropriate sections of 
all the above files replacing security sensitive sections (database 
username, password) with *'s or something.

Re: javax.servlet.ServletException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver

[Isen,Ciji]

I wanted to tinker around hence i decide to just test using a jsp. The 
jsp code is pasted below.

<[EMAIL PROTECTED] contentType="text/html"%>
<%@ page import="java.util.*" %>

JSP Page

<%
   Connection conn = null;
   DBManager dbMan = null;
   Context ctx = new InitialContext();
   if(ctx == null )
throw new DBLibraryBaseException("Boom - No Context");
   Context envContext=(Context)ctx.lookup("java:comp/env");
   if(envContext == null )
throw new DBLibraryBaseException("Boom - 
java:comp/env - No Context");
  
   DataSource myDataSource 
=(DataSource)envContext.lookup("jdbc/EconDollarsDB"); 
   if (myDataSource != null) {
  conn = myDataSource.getConnection();   
   }else{
   System.out.println("jdbc/EconDollarsDB' is 
an unknown DataSource");
   }
   %>



Pasted below is the server.xml files part that i added.

   
 
   url
   
jdbc:mysql://localhost:3306/EconDollars?autoReconnect=true
 
 
   validationQuery
   select * from major
 
 
   maxIdle
   5
 
 
   maxActive
   20
 
 
   driverClassName
   com.mysql.jdbc.Driver
 
 
   maxWait
   1
 
 
   username
   asdf
 
 
   factory
   org.apache.commons.dbcp.BasicDataSourceFactory
 

   password
   asdf
 
   

This is placed inside GlobalNamingResources.

I had tried that. It used to be in commons but felt may be its not able

Hi,
If it's inside GlobalNamingResources, you need a  to it in
your Context.

You should also place a  in your web.xml, but you may have
done that already (you didn't post web.xml).

looking for tomcat/mysql examples

[Harold Pritchett]

Hello again.  In a couple of weeks, I am giving a seminar on
installing and configuring software to create an open-source
web site.  This is to be a hands-on lab with the attendees
actually installing and configuring the software.  It's an
all day affair.
The software I'm using for this program includes:
SuSE Standard Server 8.0
openssl 0.9.7d
Apache HTTPD 2.0.50
Sun Java j2sdk-1_4_2_05
Jakarta Tomcat 4.1.30
Jakarta Tomcat Connector jk2-2.0.4
MySQL 4.0.20
I need one more thing for this.  I'd like to find a simple
application demonstrating the accessing of a MySQL database
from the web via a tomcat application.  Either a JSP or a
servlet (which ever is simpler.)
Does anyone have any suggestions where I can find such an
application (or have any code they wish to donate to my
cause?)
Thanks again for the help
Harold

RE: looking for tomcat/mysql examples

[Shapira, Yoav]

Hi,
Maybe something like this would be helpful for you:
http://www.developer.com/java/data/print.php/10932_2172891_3.


As far as Tomcat is concerned, all DBs are the same.  Tomcat provides
support for connection pooling for J2EE DataSources.  By default the
implementation uses DBCP (http://jakarta.apache.org/commons/dbcp).  The
Tomcat DataSources how-to has MySQL configuration examples:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples
-howto.html.  The application code is standard again, not specific to
Tomcat or MySQL.  Any JDBC app will do.

What's the servlet spec declared in your deployment descriptor? 
2.3 or 2.4?  Servlets as welcome files was added in the 2.4 spec.

Subclassing ServletOutputStream/PrintWriter

[Kaleb Pederson]

I'm receiving a committed response object in an Servlet that I wrote.  As the 
response is committed, as far as I can tell, I need to create a custom 
HttpServletResponseWrapper. But as the response object is committed, it needs 
to use a new print writer or output stream.  So, as far as I can tell I need 
to do the following steps:

1) Subclass HttpServletResponse wrapper which overrides getWriter() and 
getOutputStream().
2) Subclass PrintWriter (so getWriter will return a non-committed object)
3) Subclass ServletOutputStream (so getOutputStream will return a 
non-committed object.)

Although I know write(int) needs to be implemented by ServletOutputStream, I 
don't see how that would be nearly sufficient?  How does Tomcat get at the 
buffer associated with an output stream so that it can send it to the client?  
What should my required steps be?

Thanks for the help.

Differences in classloading in Tomcat 5?

[dhay]

Hi,

I inherited an app that used Tomcat 4, and we are updating it to Tomcat 5.

It runs a web app with a custom built server, and the previous owner
created a custom web app class loader by changing the tomcat
WebAppClassLoader to also load libraries found in /WEB-INF/bin folders.

I have made the changes to the Tomcat 5 classes, but it doesn't seem to
find the class - gives me an error:  java.lang.UnsatisfiedLinkError: no
dpsk in java.library.path

Has anything changed that's likely to cause this, between Tomcat 4 and 5?

Many thanks,

David

Re: PersistentManager and Session Update

[Jules Gosnell]

Linder,
Last time that I looked at the PersistentManager the impression that I 
got was that it was not designed for use within a cluster, but rather 
within an isolated node. The move to a clustered mode of operation 
introduces many new problems into state management.

WADI (wadi.codehaus.org) is written specifically to resolve these 
problems. We are not yet production ready, but you may want to cast an 
eye over the project and, if interested in these issues, join the 
mailing list.

Cheers,
Jules

Hi,
I have a problem with the configuration of the PersistentManager and session update times. I would like to share sessions across a cluster (managed outside of Tomcat) by having the PersistentManager write and read session data to and from a database. 

I tried to configure the PersistentManager to update the session data immediately, and 
with Tomcat 4.1.24, this works as I would have expected. In Tomcat 5 (the version we 
use on the production system), the PersistentManager seems to update the session entry 
every 60 seconds, no matter what I set in the configuration. I have tried this with 
Tomcat 5.0.19 and 5.0.27, and both with the JDBCStore and the FileStore.
What am I missing? My configuration follows below (I have tried it with 0, 1 and -1 as 
parameters to the time intervals).

Khalid,

Search the list...  You will see that Windows 2000/2003/XP services need
to 
know how to "log into" any data bases in order to access them.  One of
the 
biggest problems with services is accessing "mapped" files or files that

require "user permissions."  It is unfortunate, but a fact of life on
Windows 
2000/2003 and XP.

Just a thought...  Can you use the "personal" version of SQL Server
2000/2003 
instead of Access?  I believe Tomcat service will access this just fine.

Same with MySQL and Postgres SQL.

I think the line above describe your problem.
Your should set environment variables JAVA_HOME to the folder of Java 2 SDK
installation.

One more thing.. you should use Java SDK (j2sdk1.4.2_03)
instead of Java Runtime Environment (j2re)

isapi_redirector2.dll - IIS redirecting to multiple Tomcat instances

[Matt Krevs]

Hi all,

I'm using isapi_redirector2.dll to redirect webapp requests on my IIS
server to tomcat.

Is it possible to make this single redirector redirect requests to
different
instances of tomcat (depending on uri)?

For example, a request to IIS for "/app1/" should go to localhost:8080
and a request for "/app2/" should go to localhost:8081.

I'm using Windows, so if this is possible, what would my registry
entries look
like (ie: serverRoot key), and what would my workers2.properties look
like?

Thanks

When I see 2-5 times, I smell bogus results. I know that SunONE is 
professional, I know that Tomcat is free and contributed, but it CANNOT 
be 2x-5x faster. Even if SunONE is written in assembler (which I doubt).

Even if they wrote it in C++, they still need Java classloader and other

it's either misconfigured Tomcat or connector issues.
