form auth: how to get user name if login was incorrect

[Taavi Tiirik]

Hullo,

How to get a user name (and password) with form authentication,
if authentication was not successful and user was sent to error
page. Is this information lost at this moment or can I get it
somehow?

I am using tomcat 3.2.3 at the moment...

thanks,
Taavi

RE: Fine tuning my Apache -Tomcat Server

[Andrew McGhee]

Srinivas,
How about the following?
1. Ensure all loging is at warn level only (remove excessive logging of
text)
2. Install compression such as mod_gzip into apache, and configure to
compress dynamic content from tomcat
3. Remove language negotiation from Apache (unless you need it)
4. Switch to JDSK1.3 from IBM for linux (good reports from Volano site), and
arc up the amount of memory for it - use of native threads can make a
difference as well.
5. Ensure HTTP/1.1 KeepAlives are configured
6. Use AJP13 protocol for communication between Apache + Tomcat
7. Check database systems, and other back-end data sources for delaying /
causing slowdowns in operation - this is the source of about 80% of problems
we have encountered in slow systems.
8. Implement data caching on your app server.
9. Find out which java code is causing the problems (sorry this sounds
obvious, but often overlooked) - 90% of a time is spent in 10% of the code.
10. Lots more - but difficult without viewing configuration files,
application and method of operation - and there should be a lot that can be
added by others on this list. (And actually, it may be better to isolate
exactly where it is that it is going slow...)

You are only getting one user every 6 seconds, so as long as you can serve a
request in that time, you would rarely have any concurrency issues.

Be good to hear of advice from others, and their experiences regarding this.
There is probably a wealth of information out there regarding this, and a
lot of it probably won by many hard slogs.

Regards,
Andrew

Re: Tomcat crashes simultaneous more connection above 990+

[Santosh Pasi]

Hi Jeff,

Thanks for your reply.  And good link, really useful.

Here are results of our troubleshoot :(
On PIII 600, 256 Mb RAM, IDE Harddisk, RedHat Linux - 
total no. of max. connection 990-1000 and finally tomcat crashes.  But 
still apache, ldap and other applications are still running perfectly ok.
On RS/6000, AIX 4.3, 1000Gb RAM, etc
Total no. of max. connection 1600-2000 and finally reponse time 
increases specially from tomcat.  But still apache, ldap and other applications 
are still running perfectly ok.

inetinfo.exe crashes with Tomcat 3.2.3

[Claes Holmerson]

Hello!

I am trying to set up IIS 4.0 together with Tomcat 3.2.3 according to the
Tomcat IIS howto. Big problems though. When I try to access
http://localhost/examples/jsp/index.html, as the howto tells me, I get a Dr
Watson dialog telling me that inetinfo.exe has crashed. It happens every
time. I am using NT Server 4.0, sp 6a and IIS 4.0. 

Any clues to why? 

Thanks, 
Claes

In fact, tools.jar is the only extra file needed. J2SDK is huge and as Java 
improves, this becomes worse and worse. Java 1.4 distrib. is about 50 MB 
and requires more than 4 hours to be downloaded with a basic modem...

Various versions of tools.jar can be found on public ftp servers.

If I call session.getAttribute("j_username") on an error page, the

Re: javax.servlet.ServletException: No suitable driver

[Richard Draucker]

Your classpath indictes you're using the mm.mysql src distribution.  I don't 
know that this includes the compiled classes (then again, I don't know that 
it doesn't).  
None the less, put mm.mysql-2.0.4-bin.jar in either $TOMCAT_HOME/lib or your 
application's WEB-INF/lib (you might have to create this dir) and forget 
about the classpath.

Re: Trouble running a servlet

[Richard Draucker]

Your output from starting TOMCAT (in your earlier post) did not indicate a 
context being created for "ROOT", just "examples" and "admin".  Try putting 
it in the "examples" application and use the same url syntax:

http://localhost:8080/examples/servlet/LibraryServlet

As delivered, TOMCAT uses ROOT as the default webapp.  So, you may also be 
able to reach the application at:

http://localhost:8080/servlet/LibraryServlet

If you have to modify Tomcat to do it, that means your web app will only
ever run on your modified copy of Tomcat.  If you move to JRun, ServletExec,
or any other commercial container, you will not be able to modify the source
code.  The servlet specification exists for a reason =)

Re: javax.servlet.ServletException: No suitable driver

[Rob S.]

I always wish I was better with JDBC, but I never manage to find the time to
get down with it... Anyway, did you load the JDBC driver class?  Just
putting it in your classpath doesn't mean that it gets loaded.  To me, it
would appear that the "no suitable driver" when you're trying to connect to
the database would mean that DriverManager.getConnection can't find a
suitable JDBC driver ;)

RE: javax.servlet.ServletException: No suitable driver

[Mills, Theo]

Also, you're pointing to the src jar... if all you have are .java files in
there, things aren't going to work. I dunno if that's the case here. Might
want to check your jar.

Newbie wants to compile mod_jk for existing Apache sans apxs

[Bernard T. Higonnet]

Hello,

I have Apache 1.3.19 plopped down on my system as a result of installing 
Mandrake 8.0. I have installed tomcat 3.2.3 from the tarball and it 
seems to work to the extent that I can look at the examples at 
localhost:8080/examples.

I have the source code for mod_jk but I can't follow the instructions in 
mod_jk-howto.html because I have no apxs (at least that's what find 
says) since I didn't build Apache myself...


TIA
BT Higonnet

Re: Newbie wants to compile mod_jk for existing Apache sans apxs

[e-value - Maxime Mathon]

apxs is in you apache/bin directory (ie /usr/local/apache/bin)
set APACHE_HOME if you want to be clean.

In src\org\apache\tomcat\request\AccessInterceptor there is a class named
FormSecurityCheckHandler.  The doService method is where Tomcat moves the
values from the request to the session.  Here you could move the username to
the session. Also in that same file is a class FormAuthHandler.  Its
doService method is where Tomcat removes j_username from the session if the
user has an invalid login.  I've modified a lot of this code (I need to have
three things to identify a user, not just two) and am not sure which one was
the least intrusive change to allow me to get the username for an invalid
login.

But if you need to do things that Tomcat can't allow you to do (have three
criteria for login), then you don't have much of a choice - at least you can
modify the source instead of complaining to Tech support and not having any
other options.

Well, no. That's my problem.

On my machine (a standard Mandrake installation (I did not tell it to 
put apache in some funny place) as far as I am aware) there is no 
/usr/local/apache/bin.

The result of "find / -name apxs" is nothing.

"which apxs" says he can't find it.

The only other thing I can add is that, curiously, I do have the man 
page for apxs???

tag error

[Jacobs, Tim W]

I'm running Tomcat 3.1 with JDK 1.3 on win2000. I get the following error on
one of my applications:
 
Unhandled error! You might want to consider having an error page to report
such errors more gracefully
 
java.lang.NoSuchMethodError
 at
org.apache.jasper.compiler.TagLibraryInfoImpl.createAttribute(TagLibraryInfo
Impl.java:502)
 
Any ideas on what might be wrong?
 
Thanks,

Servlet design question.

[A.L.]

I am trying to create an internet based calendar
system similar to the one available at yahoo.com.  My
question is about the best way to design this system.

Currently I have a servlet whose main role during the
doget/dopost methods, is to create a monthlyCalendar
object and a dayCalendar object.  The drawMonth method
of monthly-calendar returns a String that is the html
code for a monthly calendar.  The dayCalendar object
calendar creates a database connection and the drawDay
method returns html code with the data from the
database for a specific chosen day.

  The doGet, doPost Methods of calendarServlet, simply
outprintln the strings returned by the monthlyCalendar
and dayCalendar objects' drawDay and drawMonth
methods.


My first question,  

Is this good design?  Are there any better
suggestions?  

 My second question is more specific to the code:
the drawMonth method of monthlyCalendar returns a
table which represents the chosen month.  I would like
each item in the table(which represents a given day of
the month)to be text, which when clicked will change
the arguments calendarServlet sends to the drawDay
method of dayCalendar.

  Any suggestions on how I can do this?



Thanks,
-Amos



p.s.  As in an earlier request, this question is not
specific to TomCat, yet I have been told that it is
o.k. to ask general servlet questions here.  If anyone
has a better place for me to ask general servlet
questions I would be happy to ask them there.

You'll never handle 10.000 connections on this thing... Get a decent
operating system and more ram :). If you're using native threads, there's a
limit of processes the kernel can spawn (and since threads are processes on
linux, you might be hitting that limit), and a limit on the number of file
descriptors open system-wide (and that's the other one you might be
hitting), or file descriptors open per-process (1024, so pretty close to
what you're observing, I believe that's it).

Dunno anything about AIX... But if response time increases, I believe it's
because you're using green threads, and the JVM slice takes more time to
figure out what green thread is active and what is not, rather than serving
requests... Try native threads...

Re: tag error

[Rob S.]

I can't say that I've seen this SPECIFIC error before, but if it's trying to
create an attribute and you're getting a "NoSuchMethodError" it looks like
you have an attribute in a custom tag, but not corresponding setter in the
tag class.  Or maybe no description of the attribute in your TLD.

I won't tell you what you can and can't send of course, but a better place
would probably be a general servlet or JSP or webapp forum.  We get more

My JSP pages are freezing !!

[Christian Cleber]

 Hello all ! I have tomcat 3.3  with apache and it seems work fine
until now. I have a JSP page that receive
only one param , execute a query in a database (interbase) , and
make the output.
All work fine during some time but suddenly, when i execute the page
with different values for the param, the output
is always the same , i.e., the output always show the answer not matter
what value i put for the param.
It seems like the page freezing with an old value .

RE: Integrating Tomcat with Other Servers

[Brandon Cruz]

Well, whatever version can most easily integrate with other servers would be
the one I would use.  We have a Java application that is used by many
different companies.  In many cases, they already have the capability of
running the application, but if not, I am looking for a good servlet
container to plug into their existing web server.  I would like to recommend
Tomcat whenever possible, but I need to know where it can work, and where
I'll need something else.

As far as I know, it works with Apache, IIS, Netscape, and maybe Domino.

Resource Bundle issues

[Justin Nichols]

Here's what I'm using:
Tomcat 3.2.3
JDK 1.3

Ok...here's a problem I'm having:

I am trying to use a ResourceBundle to get configuration data for the system.
The file I have is called foo.properties and the contents of the file is as 
follows:
key=value

I then put foo.properties in WEB-INF/classes because WEB-INF/classes and 
WEB-INF/lib are put into the classpath by tomcat by default, or at least it 
is supposed to.

Now from a servlet somewhere in WEB-INF/classes, I attempt to create a 
ResourceBundle using the static .getBundle("foo") method which should return 
a reference to a PropertyResourceBundle and thusly should allow me to get the 
keys and values from the foo.properties file.

What is happening is I am getting a MissingResourceException when it tries to 
do .getBundle().  However, if I add the path to foo.properties explicitly in 
the classpath, it work perfectly.  It looks to me like WEB-INF/classes isn't 
getting put into the classpath correctly when tomcat starts up, but 
jasper.log shows that it is.

I even tried to put foo.properties into a jar file and put that into the 
WEB-INF/lib directory but with no luck there either.

I'm looking for reasons why this is happening and how to correct it, not just 
ways around it.

Any answers, ideas, etc?

Thank you,

Justin Nichols

There seems to be something more sinister going on. I get the same error if

foo1.jsp does not. And all I'm doing is a file copy!

Changing the TARGET from Servlet for displaying something on theclient.

[Chinni . Venkateswara]

I have an issue here with Servlet and TARGET ( ).
Once I submit the FORM to a Servlet with a specified TARGET in the FORM
tag, can I change the TARGET in the Servlet  code to some other form.

Can any one tell me how can I do it.

FYI: I use the following code to forward to a JSP from the Servlet.

RequestDispatcher dispatcher =  getServletContext().getRequestDispatcher
("/.../test.jsp");
dispatcher.forward(request, response);

Thanks for your help.

Re: Trouble running a servlet

[Kenneth Litwak]

  I'm afraid this it doens't work in ROOT or examples.
How would I create a context for ROOT?  Another pster
told me I needed to look at my servlet.xml file which
should be in the config directory.  I don't know how
the names difer between platforms, but my "Conf"
directory under jakarta-tomcat-3.2.1 doens't have a
servlet.xml file.  What ight it be called instead on
Win 2000?  Thanks.


Ken

Your output from starting TOMCAT (in your earlier 
post) did not indicate a 
context being created for "ROOT", just "examples" 
and "admin".  Try putting 
it in the "examples" application and use the same 
url syntax:

http://localhost:8080/examples/servlet/LibraryServlet

As delivered, TOMCAT uses ROOT as the default 
webapp.  So, you may also be 
able to reach the application at:

http://localhost:8080/servlet/LibraryServlet

TC 3.3 ROOT context and PHP at the same time

[Hans Schmid]

Hello,

is it possible to have a root context webapp (no JSP's - so no filename
ending mapping possible)
and PHP working at the same time?


Let me explain our situation:

We have an old web application running under Jserv and Apache. (it does not
know about webapps)
(Apache 1.3.19, mod_jserv, Jserv 1.1.2)
This Application makes also use of PHP modules (PHP 4.0.5)

Now we are developing new modules (basically replacing old parts of our
application)
with a Velocity based approach.

Therefore we have to migrate to a Servlet 2.2 Container -> Tomcat 3.3.
(Apache 1.3.19, mod_jk, Tomcat 3.3b1)
+ PHP 4.0.5 or so

Status:
- New parts work fine in their webapp context
- Old application works fine in root context but no PHP
- Links form the old world to the new modules do work corectly


Now my problem:
I have to mount the old parts of the application to the ROOT context in
order to make
it work (runs perfectly without the PHP bit)

 JkMount /* ajp13

But: Apache then does not serve PHP anymore (they get routed to Tomcat)

Our application does not use JSP's only servlets - so I can not use a
pattern like
JkMount /*.jsp ajp13

I have mounted the root context to my Apache htdocs directory and have a
link in there
to the WEB-INF dir with all the required stuff.

Am I completly off the track here?

IBM JDK

[Mike McGuinness]

Has anyone tried IBM jdk/runtime environment on Linux with Tomcat 3.2.3?

I'v got sun jdk 1.3, running on Red Hat 7.1, with apache 1.3.20, and 
tomcat 3.2.3.
I was wondering how or if IBM's jdk/runtime works.

Re: Tomcat crashes simultaneous more connection above 990+

[Craig R. McClanahan]

Volano (makers of Volano Chat) is a company that is naturally interested
in servers that support lots of simultaneous threads.  For several years
they've been publishing their benchmark results on the abilities of
various OS+JVM combinations to scale up to thread counts in the thousands.  
There are some *very* significant (order of magnitude) differences between
combinations.

The report makes pretty interesting reading.  Most recent edition was May
29, 2001:

No, "%CATALINA_HOME%\lib" is the right place for JARs that should only be
seen by applications.  Use "%CATALINA_HOME%\common\lib" if you want a JAR
file visible to both applications *and* Catalina internal classes (which
is rarely necessary).

Without knowing what the failure symptoms are when you put the JDBC
driver files into "%CATALINA_HOME%\lib", it's a little hard to debug "that

That's specific to the way that one particular version of Tomcat does

Re: ClassLoader

[Vladimir Grishchenko]

I don't fully understand your setup from the messages you sent but if you
have a custom class loader then you should register webapp class loader to
be the parent of your custom class loader. So, if your custom class loader
lives in webapp directory its constructor should look like:

public class CustomClassLoader
{
   public CustomClassLoader()
   {
super(this.getClass().getClassLoader()  //1
   }
}

and then load your classes like

CustomClassLoader ccl = new CustomClassLoader();
Class clazz = Class.forName("xyz.zyx.Foo", true, ccl);

if you skip lilne 1 or have just call to super() then there's simply no way
you can load classes from webapp directory through this classloader, unless
it's implemented that way (btw it's a bad idea) , because system class
loader is set as the parent of ccl, and sys class loader has no clue of how
to load classes from webapp directory.
So, if you write your class loader the above way ccl will first try to
delegate class loading up the class loader tree, which will fail, so it'll
try to load the class itself. As the result of loading class xyz.zyx.Foo any
intefaces loading it implements will be unitiated through ccl, which will be
delegated to webapp class loader, so there should be no problem finding them
in jar files located in webapp directory. There's also a possibility you can
get nasty ClassCast exceptions because of the fact JVM considers  a class to
be a combination of class and its class loader, so the same byte array
represineting a class loaded through different class loaders is not the same
class to the JVM.

Re: Changing the TARGET from Servlet for displaying something onthe client.

[Craig R. McClanahan]

Unfortunately, TARGET is a client-side thing, not a server-side
thing.  There are no standard HTTP headers that allow the server to set
this, although there might be some browser-specific non-standard headers
to do so.

What about servlets that load at startup? Which directory does Catalina search?
For servlets that load at startup, will Catalina find servlet classes in war
files in the webapps folder? This didn't work for me.

mod_jk.so + apache

[Yann Sagon]

Hi,

I'm very new to tomcat + apache.

I've dowmloaded tomcat 3.2.3 and mod_jk.so (eapi)
I'v installed tomcat as a standalone version without problem.

Now, I want to use it with apache and some virtual hosts.

I have a probleme with the configuration of apache (I guess).
I have mod_jk.so in /etc/httpd/libexec/mod_jk.so

in my httpd.conf:

...
nb: those lines comes before mod_rewrite.so
LoadModule jk_module  libexec/mod_jk.so
AddModule mod_jk.c
##Configuration de mod_jk.c
JkWorkersFile /usr/local/tomcat-3.2.3/conf/workers.properties
JkLogFile /usr/local/apache/logs/mod_jk.log
JkLogLevelinfo
...
and then, some virtual hosts:
...

DocumentRoot /raid/ysagon/web
ServerName yanndev.local.hasa.ch
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13

...

My probleme:
when I try to start apache:

#apachectl start
Starting httpd: Syntax error on line 774 of /etc/httpd/conf/httpd.conf:
Invalid command 'JkMount', perhaps mis-spelled or defined by a module
not included in the server configuration
   [FAILED]

Thank you

Servlets that load at startup are loaded from the webapp class loader
(along with all other servlets, filters, and application event listeners),
which checks things in the following order:

  /WEB-INF/classes of your web-app
  /WEB-INF/lib/*.jar of your web-app
  $CATALINA_HOME/lib
  $CATALINA_HOME/common/lib
  System class loader (configured in catalina.sh or catalina.bat
   from a predefined CLASSPATH)
  $JAVA_HOME/jre/lib/ext (i.e. the system extensions directory)
  Java runtime classes

If you deploy a WAR file into the webapps folder, one of two things will
happen:

* The WAR will be unpacked into a corresponding directory
  and that directory will be used (if the directory already
  exists, unpacking will *not* happen, so delete the directory
  if you are redeploying an old WAR).

* If you have 'unpackWARs="false"' in the  entry
  for this webapp, the application will be run directly
  from the WAR.

but the same loading order still works either way.  I use load-on-startup
all the time on Tomcat with Struts-based apps (the controller servlet is
configured this way) and it works fine for me.  You might want to check
the log files ($CATALINA_HOME/logs/*) to see exactly what problem is being
encountered, so we can figure out what is going on.

Craig

PS:  Note that there are some Java classes which will work if you put them
in /WEB-INF but fail if loaded from $CATALINA_HOME/lib.  The key issue is
if this class needs to create an object of a class that is inside your
webapp.  When you put classes in $CATALINA_HOME/lib and try to reference
one of your webapp class names, they are not visible.

It has not been pushed out to the public web site yet.  I will ask the
spec leads for both specs about that.

The changes were mostly clarifications of internal details and corner
cases that apps don't commonly run into, but need to be defined for

Yes, based on my experience with certain applications the IBM jdk was

The other reason is I'm porting my apache/tomcat application to AIX and

Re: Trouble running a servlet

[Richard Draucker]

Before you try modifying your "server.xml" file, are you able to run the 
Tomcat examples?  If so, you should be able to drop your LibraryServlet into 
the webapps/examples/WEB-INF/classes directory and hit it at:
http://localhost:8080/examples/servlet/LibraryServlet

If you can't run the Tomcat examples, then your problem is something greater 
than matching the Url to your LibraryServlet.

Re: Re[2]: war files. (tomcat 4.0 beta 7)

[Rob S.]

Frankly, I'm not quite sure I understand what your problem is.  I've used
JDBC drivers from Oracle, Postgres, Sun, and (in a roundabout way) Versant,
and I'm yet to see anyone release a platform-specific JDBC jar.

Anyway, all I do is throw the .jar into the WEB-INF/lib path of the app that
uses it, and it always works for me.

What are you trying to do?

Hi All,

I just joined the list as I'm new to website admin duties and am
trying to 
bring up a tomcat server on a linux/apache box.
My current setup is RedHat 7, Apache 1.3.12,  jdk1.3.1, and Tomcat 
3.2.3.  I've been working on this server with my free time for the last 
month or so.

BTW,
JAVA_HOME= /usr/java/jdk1.3.1
TOMCAT_HOME=/var/tomcat


Here's my error that's in my tomcat log.

/usr/java/jdk1.3.1/bin/i386/native_threads/java: error while loading shared 
libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No 
such file or directory

Indeed this file does not exist and I'm wondering how I should go about 
fixing that.  Apache is operational and has been serving webpages for a 
while now.  I think mod_jk is loading correctly (according to logs) but I 
have yet to attempt a jsp page as Tomcat does not start for me.

Thanks for any help you can offer.

Hi,

I'm using Linux From Scratch with the latest stable glibc (at the time I 
built it) and had a similar problem. A putting a link with libstdc++-xyz (the 
one missing) to the newer version worked well, too. Downloading the compat 
libs is probably better, though.

Re: Re[2]: war files. (tomcat 4.0 beta 7)

[Richard Draucker]

Yes, of course including the jdbc jar in WEB-INF/lib is gonna make the .war 
platform specific in so far as the database is concerned.  What other option 
do you have, though?  ... do you plan to distribute EVERY jdbc type 4 driver 
with your application?  Wouldn't it be easier on you and maybe your clients 
to include just one 'example' jdbc driver in the .war and make an install 
note to replace it with the client's jdbc driver of choice along with 
whatever config info you include.  They're gonna have to config the driver 
anyway, what's an extra drag and drop.

RE: PLEASE - HELP PLEASE

Using a more descriptive title than PLEASE HELP PLEASE will help your
question get answered sooner.

You don't say if you're getting any error messages.  One comment -- docbase
must point to a DIRECTORY that holds your application context.  Yours points
at an HTML file.  That should cause problems.

are dir structure is something like this

Well, not *always* ...

For example, Oracle offers their drivers in two flavors -- one that uses
the appropriate Oracle SQL*Net installation on your system (so it is
platform dependent), and the other that does its own network
communications and thus runs everywhere.

A "type 4" driver (in JDBC parlance, )
is the kind that is portable.

Re: Trouble running a servlet

[Kenneth Litwak]

  Well, I still haven't been able to make tomcat work
for me on Win 2000.  Interestingly, I went to a
different machine, running Solaris 8.  I downloaded
Tomcat 3.2.3, instlaled it, put my code in the
Root/classes, and ran it with
http://localhost:8080/servlet/LibraryServlet
and it worked like a champ.  
The only real diference between the Solaris setup
(besdies it being Solaris) and the Win 2000 setup is
that on Win 2000, I've got Netscape set up touse a
manual proxy, and in that state, Netwcape won't talk
to the Internet.  On the Solaris machine, whre I can
talk to the Internet and also go to localhost:8080,
things work fine.  Does this help at all in
determining why the Win 2000 setup won't work? 
Thanks.

IllegalStateException with IBM

[Manish]

Hi All,

  I changed the jdk on my Tomcat today to use IBM instead of sun jdk. 
BUt since then I am getting this exception

IllegalStateException in: R(  + /myjsp.jsp + null) Cannot forward as 
OutputStream or Writer has already been obtained

I am not using any includes or forwards in my jsp page. I am using RequestDispatcher 
in the servlet to forward 
the request to the corresponding page. Is this is a bug in IBM or something that I 
might be doing wrong.

Please help

Thanks

Multiple servlets using same initParameters

[JBrawner]

I have multiple servlets in the same directory and they all get the same
init-params from web.xml.

Currently, I have 5 servlets and am required to repeat all the init-params
5 times, one for each servlet.  So if one parameter changes, I have to
change it five times in web.xml. I'd like to only have them in the web.xml
file once and all servlets use them.  How is this possible?

One approach I took was to create a servlet that all my other servlets
subclassed and all it did was grab the init-params.  I couldn't get it to
work.

Any ideas?

Thanks,

Re: Multiple servlets using same initParameters

[Peter Davison]

How about this:

Set up your init params for one of your servlets.
Make sure that this servlet get's pre-loaded first before the other
servlets.
Have the init() method of that servlet store all the parameters as 
System properties and let the other servlets retrieve the parameters
as System properties instead of init params.  A bit of a hack but it 
works.

Use a config file or properties file makes life a bit easier.. (at least

Re: Tomcat crashes simultaneous more connection above 990+

[Barnabas Yohannes]

Looks, like my webpage at tomcat is crashing because of many people trying
to access the page simultaneously.  Where in tomcat do you check to see how
many concurrent connections are connected?

RE: Multiple servlets using same initParameters

[Jim Urban]

This may not work, but is worth a try...

Create a servlet which does nothing other then read the init parameters into
static variables and provides static functions to access the variables
containing the init parameters.  Then in web.xml tell this servlet
1 so it will be always be the first
servlet loaded.  Then when you need to change a parameter you simply change
it once and restart Tomcat.

Subject: Multiple servlets using same initParameters


I have multiple servlets in the same directory and they all get the same
init-params from web.xml.

Currently, I have 5 servlets and am required to repeat all the init-params
5 times, one for each servlet.  So if one parameter changes, I have to
change it five times in web.xml. I'd like to only have them in the web.xml
file once and all servlets use them.  How is this possible?

One approach I took was to create a servlet that all my other servlets
subclassed and all it did was grab the init-params.  I couldn't get it to
work.

Any ideas?

Thanks,

Re: Multiple servlets using same initParameters

[Jan Labanowski]

In web.xml:


  open-port
  7180
  Port for regular HTTP via Apache


  secure-port
  7143
  Port for HTTPS via Apache


and in the jsp page:



parameters are:
open-port=<%= application.getInitParameter("open-port") %>
secure-port=<%= application.getInitParameter("secure-port") %>



or in the servlet:

String open_port = getServletContext().getInitParameter("open-port");
String secure_port = getServletContext().getInitParameter("secure-port");

Maybe enabling filtering by headers will help. That message had

some better filtering, or I don't know :) :) :)

All of them (well, most of them) gave Precedence: bulk :(

All the mailing list messages have Precedence: bulk :)

What I do on my lists is restrict posting to list members (and I have a 
secondary list of approved posters for people who subscribe from one
address, and post from another, it's usually easy to figure those out
after the first or second bounce and add them to the list)

Re: Tomcat 3.2.3 class loader hierarchy

[Craig R. McClanahan]

On Tue, 14 Aug 2001, Justin Nichols wrote:

> Can anyone tell me the class loader hierarchy of Tomcat 3.2.3 as it relates 
> to the CLASSPATH?
> 

Here's the hierarchy (bottom up) for Tomcat 3.2.3:
- Webapp class loader (WEB-INF/classes and WEB-INF/lib
- System class loader (i.e. contents of CLASSPATH, but see below)
- Extensions directory ($JAVA_HOME/jre/lib/ext)
- Java runtime library

There are three VERY important differences from the Tomcat 4 behavior that
was discussed earlier:

* Tomcat 3.2.3 core classes are loaded by the system class loader
  as well, along with the classes it requires (like an XML parser).
  Tomcat 4.0 core classes are loaded by a different class loader
  that is not visible to webapps, so it can use it's own XML parser
  without impacting what webapps use.

* Tomcat 3.2.3 builds a CLASSPATH for the system class loader that
  starts with what you already have on it, and then tries to add
  all JAR files in the "lib" directory.  Tomcat 4 ignores any
  CLASSPATH setting you had before (I think 3.3 does this too).

* When searching for a class, Tomcat 3.2.3 always follows the
  usual Java2 delegation pattern (ask my parent class loader if
  it has the class, and only look locally if it doesn't), while
  Tomcat 4 obeys the new statement in the Servlet 2.3 spec which
  allows the webapp class loader to look first before delegating.

The difference on the third point will show up if you have a JAR file
(say, a JDBC driver) in both the Tomcat "lib" directory *and* in
/WEB-INF/lib for your web app.  Under Tomcat 3.2.3, the version in the
Tomcat "lib" directory will always win.  In Tomcat 4, the version in the
/WEB-INF/lib directory will always win.

Re: Trouble running a servlet

[Kenneth Litwak]

   Okay, I made my Win 2000  trouble go away by
removing proxy settings in NetscRape and signing on to
the Internet through my ISP.  Now everything works
fine.  The question I have still, however, is:  how
can I avoid this?  I should not have to tie up my
phone line just to use Tomcat on my PC.  That's silly.
 How can I get around this please? Thanks.
