Hi Jeff,

Thank you very much for the detailed outline.
The reason why I wanted to use a central library was that I wanted to 
prevent different versions of my core libs haunting the contexts of the 
Tomcat server.  So you're suggested solution would be to leave it up to 
the separate contexts to update and use the newer lib files.

The only drawback of this terms of use is, that you have one component n 
times installed across the various contexts of the Tomcat. This was what I 
wanted to avoid

So to use both ideas, what about the following:
*) central repository of all versions of all helper jar files
/{$tomcat_home}/repository/v1.jar
/{$tomcat_home}/repository/v2.jar

*) each application context picks the version it likes to use
/{$tomcat_home}/webapps/myapp/WEB-INF/lib/link to v1.jar
/{$tomcat_home}/webapps/myapp2/WEB-INF/lib/link to v2.jar

Do you think the approach outlined above makes sense?
I think this would reduce the scattered library version troubles and it 
would even be possible to search all the contexts to find out which 
versions are used.

Thx for your feedback
Johannes

RE: Reloading shared/lib JAR files?






Also, from a release management standpoint, the risk is the dependency of
all the apps on the specific versions of the jars in shared/lib.  Meaning,
if one app needs a newer version of a shared component placed in 
shared/lib,
then all are forced to upgrade as well.  Timing on upgrading the other 
apps
is not usually so helpful, particularly when needing even a small coding
change!

It is typically better to use the source control tool to integrate 
specific
versions of shared components into its own codeline - so the codeline is
complete without external dependencies (reproducible builds from the 
source
tree).  If it is a 3rd party component, check-in the distributables and
integrate/merge the right versions of them into your different product
codelines.  If it is your own component, do the same - check-in the
distributables.  For deployment, as part of the normal 
build/package/deploy
process, place the shared components in WEB-INF/lib so each app can have 
its
own version.

As Tim says, this would rethink the design and solve the problem by not
having anything in shared/lib.  At the same time, eliminating a potential
cross-application dependency problem.

Disclaimer - there may be something in your environment that forces you to
use shared/lib (or possibly never even have an upgrade problem), whether
technical (can't think of much other than large footprint jars) or
political ;-)

Your mileage may vary.

 If you redeploy jars into /shared/lib - they will not be
 reloaded on a
 webapp reload and there is no way to reload them(except a
 stop/start of
 tomcat). But jars/classes in WEB-INF/ can be reloaded.

 If you have jars in shared/lib that need reloaded when an webapp is
 reloaded - you might need to rethink the design of those shared libs.

  Is it possible to also include the shared/lib directory?
 
  We have some helper JARs, which are used by four web
 contexts, so I'd
  prefer to put them into /shared/lib.
  However, if it doesn't get reloaded after an update of
 /shared/lib, I have
  no means to perform a hot redeploy if only the JAR files change.

Handling release management with Tomcat

Hi there,

We have a multiple server and multiple release system using Tomcat 4.1.18.
Given the issues we have to address we want to ease updating from version 
to the other without facing big risks or interoperability issues. Servers 
acting as clients calling soap requests etc. should be able to stick with 
lower-level releases or test beta-releases easily.

I'd propose the following procedure for dealing with multiple releases 
easily:
{$TOMCAT_HOME}/webapps/myapp-1.0
{$TOMCAT_HOME}/webapps/myapp-1.1
{$TOMCAT_HOME}/webapps/myapp-1.2beta
{$TOMCAT_HOME}/webapps/myapp-1.3alpha

main application entry:
{$TOMCAT_HOME}/webapps/myapp

Above are the separate versions of the Tomcat Contexts of myapp. 
To switch between the different versions of myapp, two options exist in my 
opinion:
*) using a symbolic file system link to point to the version of myapp 
which is the lead version
*) using JK to link to the proper myapp-x.x directory (only possible with 
Apache/Tomcat connected with JK).

Which version do you think is preferable? 
Do different options exist which make more sense?

The release management should allow to:
*) decide to still take the lower level release (e.g. 1.0) explicitly, 
so clients could take the link with myapp-1.0 to do so. 
*) decide to test a higher level beta release (e.g. 1.2beta)

However, the main entry focuses on the current release. Hotfixes could 
be dealt with that system as well.

What do you think ?

Thanks Micael. Tried the same thing and got the same results. 
Looks like Catalina/Tomcat is indeed using headless mode but
it's not working with my Java (1.4) and operating system (SunOS 5.6).
I'm presuming you're using this to create/generate graphics in a
servlet ?  Do you mind posting sample Java that creates a
Toolkit or MediaTracker (and which therefore requires headless 
mode) ? I can't fathom what's wrong with mine. Mine works fine
when running on Win2K and Tomcat, but now dying on Sun.

Problem with Bookmarking a Login Page

2003-03-23 Thread Mike Duffy

Does anyone know of a Struts work around for the problem with Tomact
in bookmarking the login page for container managed security?

There was a brief thread on this issue about a month ago
[http://www.mail-archive.com/[EMAIL PROTECTED]/msg59734.html]

There is a SourceForge project called SecurityFilter that can be used
to replace Tomcat's container managed security, but it would be nice
to be able to work with Tomcat.

Has anyone tried to call j_security_check directly from an Action
class?  Once you can authenticate a user you would be able to get the
roles for that user.

Is there a way to set up a JDBC Realm purely in Struts? I did not see
any information on this in a quick scan of the documentation.

Hopefully, the good people working on Tomcat see this as a bug that
needs to be fixed.

Quote from a recent thread in the Tomcat news group:  I wish that
there was a legitimate configuration change to enable you to bookmark
a login.jsp page--such as a j_success_url parameter which instructs
Tomcat where to send users if not doing an automated login process.

Another user stated, ...I simply just can't believe that there are
Tomcat instances out there in a live production environment with

Webapp Precompilation using Ant and Jasper howto

Hi there,

I read the Jasper howto 
(http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html), but I 
didn't get the build.xml file to work.

here's the commandline I typed in:

-Dwebapp.path=f:/tomcat-4.1.18/webapps/myapp

I get the following error:

Re: Problem with Bookmarking a Login Page

The way I always do it is I create a User (with email, fullName, etc.) class
which is mapped into my database to the same tables I instruct Tomcat to use
for a JdbcRealm.  Then, I set up a filter which makes sure that a User
object exists when there is a user principal.  You can use the
request.getUserPrincipal().getName() to find out the username of the logged
in user.  In your filter, you do something like...

User user = ( User )request.getSession().getAttribute( user );
if( user == null  request.getUserPrincipal() != null )
{
 user = UserDao.getUserByName( request.getUserPrincipal().getName() );
 request.setAttribute( user, user );
}

Hope this helps!

Jasper Compilation - Vol. 2 (continued from Webapp Precompilation using Antand Jasper howto)

2003-03-23 Thread Michele Neylon :: Blacknight Solutions

Hi there,

I've just built an ant task to allow for compilation of Jsps (jspc)
*) the compiled jsps are put into /web/WEB-INF/src/*.java
*) a generated WEB-INF directory is created at 
/web/WEB-INF/generated_web.xml

However, I'd like to accomplish the following:
*) automatically merge the generated_web.xml into the web.xml that already 
exists
*) deploy the webapp to the container (not only install, I mean deploy)

Has anybody done this so far?

Re: install tomat on winZP pro

I think the original poster meant Windows XP Professional.

Java in general does not deal with spaces in file and directory names 
very well.  Try installing tomcat into a directory with no spaces in the 
 names, such as:

	C:\tomcat

and, of course, set CATALINA_HOME to the same.

works. I have followed the instructions in three books, several online tutorials and 
attempted to decipher tomcat documentation on the apache site. I've installed and 
reinstalled two versions to Tomcat (currently on 4.1.24). I've modified server.xml and 
web.xml files until my fingers are sore from typing. Any help would be GREATLY 
appreciated. Nothing helps; nothing works except the tomcat examples which mock me!

Here is my problem:

From a clean install of tomcat, create a new directory under webapps called 
dumfries. Create subdirectories dumfries/WEB-INF/classes.

Copy the file HelloWorldExample.class from webapps/examples/WEB-INF/classes and 
paste it into webapps/dumfries/WEB-INF/classes

Create the following file and save as web.xml in the webapps/dumfries/WEB-INF 
directory:

?xml version=1.0 encoding=ISO-8859-1?

!DOCTYPE web-app
PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN
http://java.sun.com/j2ee/dtds/web-app_2_3.dtd;
servlet
servlet-nameHelloWorldExample/servlet-name
servlet-classHelloWorldExample/servlet-class
/servlet
web-app
/web-app

Add the following tag to the server.xml file:

Context path=/dumfries docBase=dumfries debug=0 reloadable=true /

Start the server and browse to 
http://localhost:8080/examples/servlet/HelloWorldExample;
Note that the page displays.

Now browse to http://localhost:8080/dumfries/servlet/HelloWorldExample; and behold 
the error message.

What am I doing wrong How can I make this work??? I'm supposed to be half way done 
with my project and I can't get my first servlet to work!!! Help!

You need also something like

Thank you very much.

I did just try that and it didn't help, but perhaps it's only one of many
things I have wrong.

Thanks.

Re: Help with Servlets

2003-03-23 Thread p niemandt

At least you didn't say you've tried everything: I hate that, if you
have tried everything, something would have worked ;-),
but anyways, I'm going of on a tangent ...

Firstly, your web.xml looks kinda screwed: You have nothing mapped
int the wep app.

Then, quite likely your major problem is that you have not
mapped any requests to your servlet.

You need to map your web application to it's implementation. It's not
enough to just state your web descriptor {Like your post shows}, you
will also need something like

!-- Map requests to servlet --
servlet-mapping
servlet-nameServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping

after ALL the servlet / definitions.

So something like ...

?xml version=1.0 encoding=ISO-8859-1?
!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
!-- Publish the servlet to the container --
servlet
servlet-nameYourServletName/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class

/servlet

!-- Map requests to servlet --
servlet-mapping
servlet-nameYourServletName/servlet-name
url-pattern/*/url-pattern
/servlet-mapping

/web-app

That's of course, assuming a few things ...
1. Your servlet is compiled, and a proper extension of HttpServlet
2. You want everything under
http://yourservername.domain/YourServletName to go to your servlet.
3. And probably another few things,

Hopefully this will help you in the right direction ...

Thank you. I am seeing some success with this!

If I have multiple servlets, do I need to publish all to the container

order matter?

Re: Help with Servlets

Yes, you do need to provide a servlet mapping for each of your servlets you
wish to run, unless you want to run the invoker servlet (not recommended).
Usually you map a different url pattern for each servlet in your webapp.
This can be somewhat tedious, so I use XDoclet to generate my web.xml file
for me!  But, for simple projects, this is not necessary.

Oh, yes the order matters how you define things in your web.xml file.  It
has to follow the DTD.

Re: Help with Servlets

2003-03-23 Thread p niemandt

First, as a suggestion, you will need to understand XML and DTD's: This
will explain what the web.xml file can and can not do.

Then: There are multiple ways of doing servlet mappings: I tend to stay
away from war files, for no particular reason at all, so, in that case,
I need to map all my servlets and their requests in the web.xml file. I
have no experience with war files, but understand you do / can do it
differently using that.

web.xml
You need to publish every and all servlets, FIRST.
You need to map all the servlets to their requests, after publishing all
the servlets ...

web-app
!-- Publish the servlet to the container --
servlet
servlet-nameServlet1/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet

servlet
servlet-nameServlet2/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet


servlet
servlet-nameServlet3/servlet-name
servlet-classJavaPackage.ServletClass/servlet-class
/servlet


 !-- Map requests to servlet --
 servlet-mapping
 servlet-nameServlet1/servlet-name
 url-pattern/Servlet1/*/url-pattern
 /servlet-mapping

 servlet-mapping
 servlet-nameServlet2/servlet-name
 url-pattern/Servlet2/*/url-pattern
 /servlet-mapping

 servlet-mapping
 servlet-nameServlet3/servlet-name
 url-pattern/Servlet3/*/url-pattern
 /servlet-mapping


 /web-app

etc, ad infinitum ...

hth,
Paul

My question is, what Session is related the error to? what other Session

 First, as a suggestion, you will need to understand XML and DTD's: This
 will explain what the web.xml file can and can not do.

 Then: There are multiple ways of doing servlet mappings: I tend to stay
 away from war files, for no particular reason at all, so, in that case,
 I need to map all my servlets and their requests in the web.xml file. I
 have no experience with war files, but understand you do / can do it
 differently using that.

 web.xml
 You need to publish every and all servlets, FIRST.
 You need to map all the servlets to their requests, after publishing all
 the servlets ...

 web-app
 !-- Publish the servlet to the container --

  Subject: Re: Help with Servlets

   At least you didn't say you've tried everything: I hate that, if you
   have tried everything, something would have worked ;-),
   but anyways, I'm going of on a tangent ...

   Firstly, your web.xml looks kinda screwed: You have nothing mapped
   int the wep app.

   Then, quite likely your major problem is that you have not
   mapped any requests to your servlet.

   You need to map your web application to it's implementation. It's not
   enough to just state your web descriptor {Like your post shows}, you
   will also need something like

   !-- Map requests to servlet --
   servlet-mapping
   servlet-nameServletName/servlet-name
   url-pattern/*/url-pattern
   /servlet-mapping

   after ALL the servlet / definitions.

   So something like ...

   ?xml version=1.0 encoding=ISO-8859-1?
   !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
   !-- Publish the servlet to the container --
   servlet
   servlet-nameYourServletName/servlet-name
   servlet-classJavaPackage.ServletClass/servlet-class

   /servlet

   !-- Map requests to servlet --
   servlet-mapping
   servlet-nameYourServletName/servlet-name
   url-pattern/*/url-pattern
   /servlet-mapping

   /web-app

   That's of course, assuming a few things ...
   1. Your servlet is compiled, and a proper extension of HttpServlet
   2. You want everything under
   http://yourservername.domain/YourServletName to go to your servlet.
   3. And probably another few things,

   Hopefully this will help you in the right direction ...

2003-03-23 Thread Luciano Kiniti Issoe

Hi all,

It have been a long time since I read any post... but I can't ignore someone in 
trouble.
I had a similar problem using java.AWT with linux...
It needs a graphics system server, like windows or X11 running in your server. 
But as X11 was too heavy for my system, my workaround was to start Xvfb (X virtual 
frame buffer). Google it  to 
get a Solaris Xvfb...
take a look also at

tomcat auto-configuration file for mod_jk (apache-mod_jk-tomcat)

2003-03-23 Thread Richie Chauhan

Hello,
I can't seem to figure out what needs to be done on the tomcat side to
get the Apache Auto configuration file
TOMCAT_HOME/conf/jk/mod_jk.conf-auto

The mod_jk documentation says This file is created by enabling the
Apache auto-configuration as described in the Tomcat documentation -
but I can't find any reference to this in the tomcat documentation.

When I try to to  Include this file in httpd.conf I get the following
error:

httpd: could not open document config file
/usr/local/jakarta-tomcat/conf/jk/mod_jk.conf-auto

Which makes sense as the file is not there.

Please Help!

Richie

Non-servlet application

I have an application that needs to run as a service (on Windows) responding
to various events, none of which are HTTP/servlet/JSP related.

I could set it up as a separate Windows service (similar to jk_nt_service).
However, since there is an instance of Tomcat running already, it would be
easier to write it as a Tomcat application.

Is this a suitable use for Tomcat? If so, what is the right way of going
about this?

Thanks.

servlet problems with web app outside Tomcat directory

2003-03-23 Thread Michael Harrison

Hello,

 

I've been struggling for several days with setting up a modest web
application outside the Tomcat installation directory. I have JSPs
compiling, executing, and returning the proper display data, but I
cannot get my servlets to work: I only get 404 errors.

 

I'm running Apache 2.0.44 and Tomcat 4.1.18 on Linux. I have mod_jk.so
included in httpd.conf to provide AJP connectors to Tomcat. I have a
/home/web directory set up to contain all of my sites' filesystems. One
of these--we'll call it appsite.com--is happily laid out in
/home/web/appsite.com. I take care of the virtual hosts in my Apache
httpd.conf file. I have laid out the following structure for the site:
/home/web/appsite.com/webapps/ROOT. This is where I have JSPs and static
files. 

 

I set the DocumentRoot in httpd.conf to
/home/web/appsite.com/webapps/ROOT/. I also added an include directive
to include mod_jk directives in a separate file. In the mod_jk
configuration file, I include these servlet-specific JkMount directives:

JkMount /servlet  ajp13

JkMount /servlet/*  ajp13

 

In server.xml, I have the following containers defined:

 

Engine name=Tomcat-Apache-mod_jk defaultHost=www.appsite.com
debug=0

..

Host name=www.appsite.com debug=1
appBase=/home/web/www.appsite.com/webapps

..

Context path= docBase=ROOT debug=0/

 

The servlets are located in
/home/web/appsite.com/webapps/ROOT/WEB-INF/classes/mypackage/. I'm
trying to call them through www.appsite.com/servlet/myprefix.ServletX,
and that's when I get the 404.

 

Is there something else I need to do to map servlet to the
webapps/ROOT/WEB-INF/classes directory of my site? 

 

Thanks,

 

Michael

RE: LE version?

Title: RE: LE version?

So it is. Thanks.

Looking at the Apache distribution site (http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.24/bin/), this is stated up front on the web page. However, this information is not present at the mirror I use to download from (http://apache.ausgamers.com/jakarta/tomcat-4/binaries/) and which I'm recommended to use by Apache, so I've never seen it. Neither is it in the README.txt in the distribution, and there isn't a README.html in the distribution bin directory.

Sigh.

load-on-startup order

Tomcat 4.1.18

I have two applications, A and B, where a servlet in B depends on a servlet
in A being up, so I have

in A's web.xml:

  servlet
...
load-on-startup1/load-on-startup
  /servlet

in B's web.xml:

  servlet
...
load-on-startup5/load-on-startup
  /servlet

which should make A start first. However, when Tomcat starts, B's init() is
called first. B's init() attempts to make a connection to A's servlet, but A
hasn't started yet, so everything hangs.

Am I doing this correctly?

Thanks.

With your setup/solution you realy can´t tell if application A will load 
before B.

Load-on-startup orders the servlets in each application (web.xml)

Re: load-on-startup order

Instead of performing the necessary logic in the init method, why not try
lazy-loading.  Only initialize whatever you need when it is requested the
first time.  By the way, what are you trying to do?  I've never heard of
anyone having this kind of requirement/architecture.  Just curious.
