Load Balancing on Tomcat.

[manish . khubchandani]

Hi all,
My webserver IIS is routing requests for JSPs and SERVLETs  to a Tomcat
Engine installed on one machine (This is working fine).
My aim is to achieve load balancing for Tomcat and distribute requests
between multiple Tomcat workers.
I am not aware of the process by which one can achieve this.
It would be a great help if anybody can please send me some documentation
illustrating the steps invloved in this process.
Do i have to use mod_jk (mostly used with Apache) to achieve this?

Waiting in anticipation...

Thanks & Regards,
Manish Khubchandani.

Shouldn't Tomcat keep on running? Or better yet, daemonize itself?

Re: tomcat session problem

Thanks Chintan, actually I heard from someone that tomcat server does not
support sessions properly at times, so, I just wanted to clarify it.

RE: tomcat session problem

[Geoff Howard]

I am pretty sure from having been through this before that Netscape and IE
differ on this issue.  The description below holds for IE, but not Netscape
which will share a session no matter how you open the 2nd window.

Hi Rinku,

Your application should work fine in both the browsers opened
simultaneously...only if the second browser window is not opened from the
first browser window using Ctrl+N

If you are opening the 2nd browser window from 1st one only... as said
above, then the session object will be single and both of the browsers will
be interacting(i.e. reading, writing or get/set) with the single session
object...and in that case, it will not behave properly.. 

ya, but if you have opened two browser windows separately, then there will
be two different session objects for each of them, you must be able to work
on both of them simultaneously..

I hope, this will help you.

Chintan.

Hi there,

I am using jakarta-tomcat - 3.2.3 server to run my project. I am finding
that session tracking, when more than one browser window is opened at one
time, doesn't come out to be correct. I am using its inbuilt session object
and the cookies are enabled in my browser. When more than one sessions are
running then the page presented is unpredictable.Sometimes correct page
displays and sometimes totally diferent page gets displayed. It works great
except if I have 2 browsers sessions up - then it gets confused and losses
track of which is the current session.

Are there any issues with the Tomcat server regarding session tracking?

Thanks in advance,

RE: File Download - CSV question ****

[Evan Swanson]

I order to reduce the variable, I tried installing TC4.0 on the same 
windows based machine. I am using the same client for both( IE5.0 ).

Results:
TC3.2 will present a popup box for downloading files with .CSV extention.
TC4.0 throws data directly up on the screen.


Is there any reason for this? Can I change the configuration? 

Is this a MIME type problem?

Are you using the same client between the two servers?  IE seems to
consider itself more important than mimetypes, and if it sees a file
extension it recognises it treats it as it deems fit, regardless of the
mimetype.  So one possibility is that you have just installed excel or
something on the client, and IE is redirecting the download there.

another option is that the mimetype being sent in tomcat 4.0 is different
to 3.x, but I'm not sure about this, so will let someone else answer this
option.

if you outline exactly what client/server you were using before, and now,
it will make the question more specific.  for intsance, tc3.2 on windows
with a win98 client with IE4.0 and now using tc4.0 on linux with a win2k
client with IE5.0.

getRemoteAddr() vs getRemoteHost()

[Miao, Franco CAWS:EX]

 When I put the following code in my Jsp, it comes up two identical
remote IP addresses, instead of one remote IP and one remote host name. My
computer  has Internet IP and valid Internet DNS server. Any suggestion
about
that?


Thanks!

out.print( request.getRemoteAddr() );
out.print( request.getRemoteHost() );

Re: Is Tomcat 4.0 Backward Compatible with 3.2.3 App??

[Vernon Wu]

We run into the compatible problem in our one module of servlet/JSP
application. A few months ago, I implemented it using the 3.x version of
Tomcat. After the 4.x version was stable, I had tried to move it over to the
Tomcat 4 for a better performence. The problem we run into is an exception
on a serializable from the DB access utility. The non-standard DB access
utility is from IBM, Informix formerly. We had reported this problem on the
support mailing list for more than a month, not response yet. I don't know
whether the problem is related with the Servlet/JSP spec or not. I would
like to know the cause.

Thanks in advance.

RE: File Download - CSV question ****

[Evan Swanson]

Thanks for answering...

That is the thing, I am using the same client in both situations.

I am using IE5.0 in both situations. The only difference is going from
TC3.2 on windows to TC4.0 on HP Unix. I would think that the IE would be
making the 
decision on how to handle the file by the extension name but it is not.

Is MIME type something you can configure on Tomcat?

Re: Precompiled jsp's

I precompile my jsps at build time using jspc.  If you add the mappings in your
web.xml, the server will use these instead of precompiling the jsps for you.

How do you precompile JSPs on startup? I know they can be precompiled if called
with that "precompile" URL. But suppose I had a lot of JSPs and I would like to
tell Tomcat to precompile a defined portion of them into run-time servlets, so I
could avoid that initial lag of first-time-run JSP.

Re: tomcat session problem

Thanks Ralph for the information, my question is when there are 2 sessions
running on the web in the same PC (by opening 2 browsers) then it doesn't
track the sessions properly and changes the value of the session when I go
to different pages even if I limit one session to one browser.

Providing for persistent files in a web-app

[Frank Lawlor]

I have a web app that allows users to add files to 
the app, some of which can be displayed via URL
references (many different file types).

Currently these files are in a subdirectory ("New") of the
web-app.  This creates a maintenance problem
since replacing the web-app (erase webapps/MyApp.war,
erase webapps/MyApp directory, and deploy new 
MyApp.war) also destroys the "New" directory.

Rather that having a complicated process of saving
and restoring the "New" directory it seems like it 
would be better to keep it elsewhere.  However, the
contents still need to be displayable in a browser as URLs.

The best approach I could think of was to add a 
simple tomcat web-app whose only purpose is to
hold the contents of "New".

Any problems with this approach?  Is there a 
better/simpler approach?

Error in mod-webapp nightly snapshot

[David Smith]

Pier -- Thought you might want to know about this (you might already).  I 
just built mod-webapp from the nightly snapshot dated 10-25-2001 and found an 
error in the build.

Line 77 of WarpConnector.java imports 
'org.apache.catalina.ServerSocketFactory' when it looks like it should import 
(at least for Tomcat 4.0.1) 'org.apache.catalina.net.ServerSocketFactory'

I made the change in the snapshot I downloaded and it built without a hitch.

RE: sourcepath problem in building tomcat (apxs pb building mod_jk.so)

[Larry Isaacs]

The Tomcat 3.3 release is built on a Sun box running
SunOS.  It has no problem using the build.xml file
as is.  I don't know why your system is having
trouble with the ';' in build.xml, though perhaps
its a JDK 1.2.1 issue, assuming thats what you are
still using.

You are correct that the "ant" build doesn't build
mod_jk.so.  Building of the native connectors is
done separately.  Given that I'm pretty much a
Windows person, and don't know much about Solaris,
someone else will have to provide advice about
how to get mod_jk.so to build on Solaris.  You might
search the tomcat-user archive to see if similar
errors have been encountered in the past.

RE: servlets path in tomcat 3.3

[Larry Isaacs]

Hi Mathieu,

RequestInterceptor is still supported, but not used because modules.xml
provides for simpler syntax in the server.xml.  Thus, the
InvokerInterceptor is still there in server.xml, but it appears as:



The class for InvokerInterceptor is now
org.apache.tomcat.modules.generators.InvokerInterceptor.  Unfortunately,
it has lost its ability to set the prefix, which is hardcoded to
"/servlet/".  I'll add the prefix property back in for Tomcat 3.3.1.
In the meantime, you could use the PasswordPrompter.war add-on module
as an example of how to create a MyInvokerInterceptor add-on module.
Modify the InvokerInterceptor source to allow the prefix to be set.
Your "interceptors.xml" might look like:









Hope this helps.

Larry

Re: Launching subprocess under Tomcat as a Service

[Frank Lawlor]

You should try to figure out what it is hanging on.
Add some tracing.

You can launch a subprocess, but it is running as the 
service user in a service environment.  This is VERY
likely different from your non-service environment.

To help debug:
  - print out the path to a file
  - print out the classpath ...
  - print out the env ...
  - remember that services are usually set to NOT be able
to interact with the desktop.  Try changing it to yes.
  - remember that it may have different permissions so
it might not have access to resources that you do.
  - remember that you cannot access mounted drives

TC4: stopping/starting an application works, reloading does not

[Wolfgang Stein]

Are there any known problems related to 
reloading of an application with the 'manager' app ?

E.g. a servlet request did not load a servlet
since i forgot to deploy the corresponding servlet class.

After deploying it and reloading the application 'myapp' with
  http://localhost:8080/manager/reload?path=/myapp
the servlet is still not found.

After doing successively 
  http://localhost:8080/manager/stop?path=/myapp
  http://localhost:8080/manager/start?path=/myapp
the servlet of application 'myapp' is loaded successfully.

The corresponding servlet entry/mapping in myapp/WEB-INF/web.xml
was already present on the first attempt.

Any similar experiences ?

Hey Alex - looks like we're on the same lists!

JDBC Realm

[Mihai Gheorghiu]

Tomcat 3.2.2 on RH7.0
I created a JDBC realm as per "JDBC Realms"
server.xml
...
 

...
Application in webapps/development/*
WEB-INF/web.xml
...


  
 Protected Area
 /*
  DELETE
 GET
 POST
  PUT
  
  
 tomcatRole
  



  BASIC
  development

...
When I try to log in, I am prompted twice:
First, a Win-like window:
Please type your user name and password
Site:xxx.yyy.zzz.ttt
Realm:development
User Name
Pasword
Save this password in your password list
OK   Cancel
Then it starts loading the applet, Java console pops up, and another window
(with Duke's icon) comes up:
Firewall:xxx.yyy.zzz.ttt/xxx.yyy.zzz.ttt
Realm:   development
Scheme:  basic
User name:
Password:
Yes   No
Once authenticated, the applet displays some data queried by a servlet.
Could this be the cause for being prompted twice?
I'd like to ask for username/password only once, in the beginning. How can I
do that, while preventing users from logging directly into the next level?
Thank you very much for your patience and support.

Re: Tomcat and firewalls...

[Barry White]

Go to the ZoneAlarm "programs" section and see if your program has access to
the internet.  If you are not sure about the settings then delete all of the
setting for  the programs in ZoneAlarm and start up Tomcat and mySQL.
ZoneAlarm will ask you if you want to allow these programs to access the
internet... just click yes.

P.S. Your problem could also be your anitvirus sorftware or w2k indexing.
Try disabling these and see if that helps.

RE: Automatic Application Deployment

[Brad . Moreland]

I actually found the problem in my web.xml file.  I sort of figured out what
needs to go in there, but I really need a tutorial that is in layman's
terms.  The docs included with Tomcat regarding the web.xml file just say to
read the servlet spec.  The servlet spec assumes that a "real web developer"
is the reader.  I need something that will help a newbie understand the
web.xml file.  Can anyone point me to some descent documentation?

Thanks in advance!!

Re: how to keep form data

[David Smith]

I would like to add to that.   It's a better user experience to do the 
validation on the client side since they don't have to actually submit and 
then wait for a reply, but definitely still validate on the server side as 
well.  All data coming into a web server should be considered untrusted until 
proven otherwise.  After all, the submission might come from one of your 
pages or some hacker trying to break/exploit your app.

As far as keeping form data, I tend to have the form submit data to the page 
it's in and then do some code to grab the data and process it.  Then forward 
the user to the next page.  Obviously do a quick check and if there is no 
form data skip the processing.  If there's a problem, then just take the 
submitted form data and enter it back in the form with value="<%= ... %>" 
attributes.

Strange problems happening with virtualhosting: URGENT

[Gabriel J Zimmerman]

Hi,

I am using Tomcat 3.2.3 on a Linux system with a setup of multiple
virtual hosts. Most of my class files are in the /lib
directory, but when I move them out, I still get these problems.

I am having two very strange problems:

First, the java classes do not seem to be able to load a properties file
located in the classes directory using the following code snipit:

InputStream is =
getClass().getResourceAsStream("/prop_file_name.properties");
Properties props=new Properties();
props.load(is);

I get a null pointer exception at the "props.load(is)" line. This would
assumedly mean that the properties file is not there, but it is there
under the correct name. In fact, this is a program copied from another
server with a similar configuration, except it did not use the virtual
hosting. This problem is especially weird, because the webapps recognize
my tld files located in the lib directory.

Second, I am using the mailer taglib, and although everything seems to
go through fine and the taglib reports no errors and there are no
exceptions thrown, the mail doesn't get sent. I tried this from all
virtual hosts on the box with the same problem both using a general mail
server and localhost as the mail server. On another box this same code
works fine, and sendmail works on the box. The code is posted below.

In my investigating this problem there are a couple direct questions:
1) Is there anything I need to do to add a virtual host to Tomcat other
than adding the following lines to the server.xml file?:

  


  

2) Might there be some problem with a class located in the
TOMCAT_HOME/lib directory trying to call getResourceAsStream on a class
that is located in an individual webapp, even if that webapp is the one
that is using the class file in TOMCAT_HOME/lib?
3) Is there anything else that anyone can think that might be causing
this?

This a very urgent problem. Any help would be greatly appreciated.

Thanks,
Gabe

Re: tomcat session problem

[Craig R. McClanahan]

It's more likely to be a problem with your application, or a
misunderstanding of how browsers handle cookies.

In general, cookies are *not* specific to a particular browser window.
Therefore, all windows that the client has open are part of the same
session.  This is the way Netscape (at least 4.7.x) always runs -- but in
IIS it's configurable.  But the bottom line is that you cannot expect each
window to be running in its own session.

Did you download the "optional.jar" file that goes with Ant, and put it in
the $ANT_HOME/lib directory?  Did you add xalan.jar (from JAXP/1.1) to the
$ANT_HOME/lib directory?  Both of these requirements are documented on the
"BUILDING.txt" step about downloading and installing Ant.

RE: how to keep form data

[Mehdi]

Ooh.. i have issue with this.  Validation should always be carried out on
the server side.

If validation is done on the client side, that is good, but server side
validation is always a must, especially if data being entered could cause
problems with data integrity ( i have seen this happen before).  Server side
code is the last defence and the safest as you dont need to worry about
whether or not javascript is enabled in their browser.

If you do the validation in the client side (using java script) you do not
lose the information. Besides this is a better approach once you don't want
your code to do the avalidation in the server side and then post that the
user made a mistake.

Keep validation in the client side always

RE: tomcat 4.0: Plug in custom Realm

[Barney Hamish]

You'll notice in the realm file there is a line that gives the class of the
JDBC Realm interceptor you're using. You should replace this class name with
the name of whatever inteceptor you want to use.

ie, change the line:
className="org.apache.catalina.realm.JDBCRealm"
to
className="my.FooBarRealm"
or whatever.

As long as this class can be found somewhere in your class path tomcat
should be able to load it.

Hello.

Is there a way to run Tomcat 3.2.3 or 4.0 so that the server will listen 
on a specific host interface (IP address)?

For example, my machine has two IP addresses (123.123.123.123 and 
111.111.111.111). I would like to run two instances of Tomcat on port 80 
each one listening on one of the interfaces respectively. I specifically 
don't want to use Virtual Hosting.

The server.xml file on both versions of Tomcat seem to take a port 
parameter but not a host parameter.

One way to solve this of course is to use Apache as a front for Tomcat. 
But I would like to use Tomcat as a standard alone web server if at all 
this is possible.

Thanks for any help.

RE: Update JSP

[Barney Hamish]

You shouldn't actually need to do anything to get tomcat to recompile the
page (assuming you don't have automatic compilation turned off). Just
request the page and tomcat should recompile it for you. If that doesn't
work shutdown tomcat, delete all the files in the $tomcat_home/work
directory and start tomcat again and it should recompile the JSP page
automatically for you.

Hi there,

I am using jakarta-tomcat - 3.2.3 server to run my project. I am finding
that session tracking, when more than one browser window is opened at one

displays and sometimes totally diferent page gets displayed. It works great

Are there any issues with the Tomcat server regarding session tracking?

Servlet Mapping -- Servlet getting called twice

[Smith, Lawrence T (Lance)]

Please HELP:
I don't know if what I am seeing is standard behavior or something I am
doing wrong.

I have the following in my web.xml file:

  CardServlet
  /Cards/*


The servlet at this point only writes out a simple hello page and debug
output of getPathInfo() and getRequestURI() but it will do some pretty heavy
processing which I don't want done twice. What is happening is as follows:

I submit the URL: 
/foo/Cards/a/b/aCard.jsp
The servlet debug prints:
pathInfo=>/a/b/aCard.jsp
requestURI=>/foo/Cards/a/b/aCard.jsp
pathInfo=>/a/b/
requestURI=>/foo/Cards/a/b/

I submit the URL: 
/foo/Cards/aCard.jsp
The servlet debug prints:
pathInfo=>/aCard.jsp
requestURI=>/foo/Cards/aCard.jsp
pathInfo=>/
requestURI=>/foo/Cards/

What I thought should happen is that I would only get called once. Is what I
am seeing the proper behavior or am I doing something wrong? Help. The first
time the servlet gets called with what I would expect the second call is
really throwing me for a loop.
Thanks for any help given.

Some things I've tried now, are:
 1. decrease the  in the web.xml
of the webapp the .jsp being tested resides in
from 30 minutes to 1 minute

 2. limit the maximum number of threads used by tomcat
by using the max_threads setting in 
in the server.xml file, as outlined in


What I thought might happen here was that I could
trade the crash for a slowdown under heavy load

What happens in 1. is that the tomcat processes don't
seem to ever get the OutOfMemoryError exception, and
die.  But the response seems to be seriously slowed
down over time.  I wonder why?  I'm also wondering if
a low  will create problems for
Struts applications?

When I limited the maximum number of threads to 30,
the footprint of the tomcat Java processes seemed
to level out at 78MB and stay there.  So I thought
things might be stable.  However with a long enough
test running, things eventually crashed.

The third line throws an exception.  The connection itself is fine,
I can call stuff like con.getContentLength() and it works (correctly)

Security Question

[Drasko . Kokic]

Hi there,
I have read the "Existing Risks and Problems" (Chapter 8 in the internal
document of the TC-3.3) and spotted that there is a potentional security
risk in using Tomcat as a platform for the Application Gateway to an
enterprise business support system.
One of very important subprojects I still need to solve is providing a
secure environment and currently we are constructing a sort of "Checking
Engine" that basically test every parameter against predescribed conditions
and reject all invalid requests.
Has anybody already thought about this or eventually produced some
code/concept?  I hope some of original contributors will also read this
post.
I have some development resources allocated to this task, but would prefer
if we could join forces with other interested parties as this must be a
very important issue.

JSP - How do I make it invisible to the browser's "back" button?

[Navarro, Jose]

Hi!

I have developed a JSP page which in turns invokes a servlet used to keep
track of the number of times a certain page in my web is visited.

In other words, when I have a link to some page, I do not link the target
page directly but execute the JSP instead. More or less it goes this way:

http://the/
desired/URL.htm" target="_self">Text of the link

(here, "thisorthatpage" stands for an achronim that is stored in my hits
database and that identifies the page being visited).

So when the user clicks on the link, he or she is redirected to the jsp page
which invokes the counter servlet and then redirects the user to the target
(destination) page.

The problem is that the jsp is stored in the browser's list of visited
pages. If then the user wants to go back and clicks on the corresponding
browser's button, the jsp page is executed again and he is redirected one
more time to the same page. The feeling, therefore, is that the back button
doesn't work at all.

Then it would be very interesting to remove the jsp URL from the browser's
access list, so the consequence would be that it would be "invisible" to the
back command. Well, I hope that it is possible to access this list of
visited pages from the jsp code and remove its own entry.

Is this possible? If so, can you tell me how? If not, do you know any other
way to implement it?

Thanks alot for your help!

Regards,

Jose.

Problems with PostgreSQL + Tomcat solved - sort of

[Nikola Milutinovic]

Hi all.

Now it's working all of a sudden. I have made three changes:

- removed $CATALINA_OPTS=-Djdbc.drivers=org.postgresql.Driver
- removed: import="javax.sql.*" from page directive
- added: Class.forName( "org.postgresql.Driver" ) to my code

Could someone answer these questions:

QUESTION 1. What is the proper way of specifying a JDBC driver in Tomcat?

In a standalone application I will use "-Djdbc.drivers=..." and it works. Tomcat, 
obviously, doesn't like it. Is there some property file, where I can specify JDBC 
drivers? I would like to make my code as independant of a database used, as possible. 
By specifying which JDBC driver I'm using and supplying JDBC connection parameters in 
web.xml I am getting there.

QUESTION 2. Should I put as a parameter in my web.xml?

QUESTION 3. How would Tomcat use JDBC realm on, say, PostgreSQL, anyway?

QUESTION 4. Could it be that importing "javax.sql.*" broke my JSP?

I was getting all sort of *compiler* errors, not runtimes. Jasper was trying to parse 
"postgresql" (inside JDBC connection string???) to Integer:

java.lang.NumberFormatException: postgresql
at java.lang.Integer.parseInt(Integer.java, Compiled Code)
at java.lang.Integer.parseInt(Integer.java, Compiled Code)
at org.apache.jasper.compiler.Compiler.getJspLineErrors(Unknown Source)
...

on Class.forName( "org.postgresql.Driver" ) it complained:

/usr/local/java/tomcat-4.0/work/mercury.ev.co.yu/addr_book/firm$jsp.java:20: Type 
expected.
Class.forName( "org.postgresql.Driver" );

It was getting very weird. Thank God, it is working now, but being an administrator, 
I'd like to know this in the future.

RE: Can't get precompiled JSP to be welcome page?

[Randy Layman]

The problem seems to be that Tomcat is scanning the file system for
the welcome pages, not including the servlet mappings.  What I do is create
a zero length file of the file name.  Tomcat will see this and redirect the
/ request to /whatever.jsp (the welcome file), which is then intercepted.
This fix only adds a few bytes (one file entry in the contents) to the
application and doesn't reveal anything about the internals that people
couldn't already easily figure out.

Tomcat does to it automatically, but there are two primary reasons that
people want to precompile JSPs for distribution:
1.  You can't legally deploy the JDK/tools.jar that Tomcat needs to
compile without an agreement with Sun.  Precompiling eliminates the need for
the JDK, simply a JRE is now needed.

2.  It makes it more difficult for people to view and modify the
source code of your application.  This way, over ambitious people aren't
modifying their source code in an effort to fix your "bugs" and crackers
have to put forth more effort to find vulnerabilities (scaning Java byte
code is more difficult than scanning JSP souce).

RE: XML ClassCastException and tomcat 4.0 documentation

[Dan Silcox]

I don't remember exactly what my error was but I rolled my JDOM 7 upgrade
back to JDOM 6 because I was having some compatibility problems.  You may
want to see if that helps.  I know JDOM6 works with the latest xerces.jar.

Subject: XML ClassCastException and tomcat 4.0 documentation


I am facing a terrible dilemma and in need of accurate information.

I believe my issue deals with the Tomcat 4 class loaders and my problem
surrounds the use of Tomcat 4.0.1 on jdk 1.4 with the JDOM beta 7 jar.

2 scenarios:

1.  unpack tomcat 4, configure the server.xml to look to my webapp.

My application WEB-INF/lib jar contains jdom beta 7 and the latest and
greatest xerces jar (built from source of xml.apache.org).  (Note that we
now have a xerces jar in the CATALINA_HOME/common/lib directory AND my
webapp/WEB-INF/lib directories)

For some reason, despite the fact that both xerces are recent, the following
exception occurs.

javax.servlet.ServletException: Servlet.init() for servlet jsp threw
exception
at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:871)
at
org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:
3267)

at org.apache.catalina.core.StandardWrapper.load
..

For some reason, the ClassLoader(?) get confused and spits back a that
ClassCastException, claiming that the xerces DocumentBuilderFactory
implementation does not implement the interface - when it clearly does.

2.  Ok, so I remove the xerces.jar from the webapp/WEB-INF/lib directory.

I startup the system.  Now the jspservlet starts fine but my own servlet
that (a few levels deeper) makes a call to org.jdom.input.SAXBuilder chokes
b/c the org.apache.xerces.parsers.SAXParser is being cast to an XMLReader.
Now I checked the xerces.jar's SAXParser class AND IT DOES implement
XMLReader, but it throws the following exception none the less.

This leads me to believe its ClassLoader issue.

My frustration comes in that the documentation (HOWTO on ClassLoader) seems
to be very inaccurate, and I am left wondering how the ClassLoaders work,
what I need to configure to seperate these jars or whatever might be needed.

Someone who knows what they're doing... please help me.  I can (and do)
duplicate the error like clockwork.  I'm certain not to be the only one with
this issue and I hope to contribute the solution / explanation to the
community.

JSP-JDBC-Problem

[Hostmaster of the day]

Hi there !

I got the following problem :

Our Tomcat 3.2.1 (RH 6.2) server is located in New York.
twz1jdbcForMysql-1.0.4-GA is installed.

Our mySQL 3.23. (RH 6.1) server is located in Baltimore.
Remote '%' access is enabled.

I'm trying to access from our NY server to the mySQL db in
Baltimore using : 

databaseURL =
jdbc:z1MySQL://www.domain.com:3306/database?user=correctuser&password=
**";

All I get is an Internal Servlet Error
javax.servlet.ServletException: The url cannot be null

I don't know what this mean.

What is my fault and what can I do against it.

Thank you,

Where to place the Login.html file

[raj]

Due to the bug (yet unresolved) in Tomcat 3.x, the Login.html and 
Error.html files cannot be
placed inside the servlets dir.

For instance:
My servlet is inside the dir called "foo" (i.e webapps/foo) and is 
called "bar".
URL pattern is "/*" for security.
This means "Login.html" and "Error.html" cannot be placed inside 
/webapps/foo.

Question: Where should I placed them instead?

I have tried to place them in webapps and declared them (in web.xml) as:
/../LoginForm.html
/../LoginError.html

but this would not work.

Any suggestion would be most appreciated. Should I try another
URL pattern?

The release note says something about placing "other" files in "other"
sub-dirs but what other files and what other
sub-dirs.

Some clarity would help, n'est pas?

Cheers

Tomcat shutdown destroy not called

[Erik B]

With small or medium load destroy is called at shutdown.
With heavy load destroy is not called at shutdown.

I have also tried ContextListeners and with heavy load
contextDestroyed is not called either.

What can I do to ensure that either destroy or contextDestroyed
is called before tomcat is shutdown.

Im using Tomcat 4 on Win 2000.

mod_webapp not forwarding

[Frank Niedermann]

Hallo!

I have a problem with Apache Webserver and Tomcat 4.0.1 on my Linux-

working because httpd -t says it's all ok:
  httpd -t:
  dettlx07:/var/log # httpd -t

Class partially reloaded even after restarting Tomcat

[Cathy Ooi]

Hi,

I don't know if anyone have come across this ...

I'm running a Tomcat-3.3-m4, with Apache 1.3 on Red Hat Linux release 7.0.
My JVM is Classic VM (build 1.3.0, J2RE 1.3.0 IBM build cx130-20010329 (JIT
enabled: jitc)).

I have 2 JSP pages menu.jsp and data.jsp that called a class DBManager that in
turn uses DBConfig that contains final static variables e.g. DBConfig.DB_URL.

Originally, DBConfig.DB_URL = "10.10.10.10:3306".
Called http://testserver/menu.jsp.
And I get an Exception "java.lang.Exception: Cannot connect to MySQL server on
10.10.10.10:3306". Perfectly okay, since "10.10.10.10:3306" is the wrong value.

So I modified to the correct value, DBConfig.DB_URL = "10.10.10.20:3388".
Compile & upload DBConfig.class again.
Remove the generated files in "work".
Shutdown & start up tomcat again.
Called http://testserver/menu.jsp again. And I get an Exception
"java.lang.Exception: Cannot connect to MySQL server on 10.10.10.10:3306" again!
But when I called http://testserver/data.jsp, the page was displayed correctly
with the data retrieved from the DB.

I've tried stopping & restarting both tomcat & apache several times but the
result remains the same. I've even 'pstree -ap' to check that all tomcat
processes has terminated. But the old value stubbornly remains after several
shutdowns & startups.

Finally, my colleague shutdown tomcat and waited about 30 minutes before
starting up tomcat again. (Previously, there's a few seconds interval between
shutdown and startup) This time, menu.jsp works correctly.

Is there anywhere tomcat might have cached the class or value?
Is there a faster way to get the static final value reloaded?

Thanks in advance.

Cathy.

p.s. There are 2 other J2SE applications running in the same server, but I don't
think this should matter since they're both running in different processes,
right?

As seen in the doc, an url path can be sliced in

Actually I use jserv and I have the following directive

Yes, this is probably what happens.

It looks like the --session-cookie and --wsess arguments
to httperf may be doing what you suggest.  And using
this argument may give a more realistic test (I'm
running one right now).

But it doesn't address my real worry at the moment:
that a script kiddie armed with nothing more than
the httperf testing tool can bring my tomcat to 
crash.

Hm... yes, but our actual application (not the test
page I've done the current tests on), will be Struts
based, and I don't think Struts will work without
sessions...?

Thanx!

one simple thing, just try it out

i.e. in browser window location bar :
http: and see, if it opens up
the file in browser or pops up 'save as'  dialog box.  If it shows u "save

RE: tomcat session problem

[Shah, Chintan V (Chintan)]

Hi Rinku,

Your application should work fine in both the browsers opened
simultaneously...only if the second browser window is not opened from the
first browser window using Ctrl+N

If you are opening the 2nd browser window from 1st one only... as said
above, then the session object will be single and both of the browsers will
be interacting(i.e. reading, writing or get/set) with the single session
object...and in that case, it will not behave properly.. 

ya, but if you have opened two browser windows separately, then there will
be two different session objects for each of them, you must be able to work
on both of them simultaneously..

I hope, this will help you.

Chintan.

Hi there,

I am using jakarta-tomcat - 3.2.3 server to run my project. I am finding
that session tracking, when more than one browser window is opened at one
time, doesn't come out to be correct. I am using its inbuilt session object
and the cookies are enabled in my browser. When more than one sessions are
running then the page presented is unpredictable.Sometimes correct page
displays and sometimes totally diferent page gets displayed. It works great
except if I have 2 browsers sessions up - then it gets confused and losses
track of which is the current session.

Are there any issues with the Tomcat server regarding session tracking?

I perhaps wasn't too clear about what I was doing.
There is no real application involved in the tests
I'm mentioning.  It's just a simple JSP page _hammered_
by requests.

The usage is atypical, I'm the first to admit, but it
worries me that hammering the server with requests
can make tomcat _crash_ (ref. DOS attacks).

In fact, the crash is the real worry.  Why does a
single OutOfMemoryError cause _all_ tomcat processes
running under apache control to crash?

AW: tomcat session problem

[Ralph Einfeldt]

It's not a tomcat issue, it more an issue of your application.

If you open a second windows from a running session, the windows 
will share the session from tomcat. From the view of tomcat the 
windows are indistinguishable from each other. Tomcat even can't
recognize that there are two windows (That's true for any server
that talks HTTP with its clients). 
So if you want to allow more than one window, your application
has to take care of that.

There is only one webapp. 
btw, I have some files like jar_cache22482.tmp
Who is caching these. Is it jvm, or tomcat, 
or cos.jar ? Any idea? More over, I get these
tmp files only with tomcat 4.

For me, the second upload works only if I

Neither. Type 'java -X' to see the options. You probably want -Xmx and
-Xms. You can set these in your TOMCAT_OPTS variable rather than edit
tomcat.sh

Re: sourcepath problem in building tomcat (apxs pb building mod_jk.so)

[Bill Cai]

I think the problem is it didn't like the ";"s in the
value of "sourcepath". It no longer complains after I 
changed them to ":"s. I guess the source was for 
Windows platform. On Solaris ";" means end of the
command...

However, it still complains about "srcdir" in the
following block:

  


Actually, what I want is "mod_jk.so". Not sure "ant"
it
will build the whole thing including mod_jk.so? I
went to build/tomcat/apache1.3 to build mod_jk.so
individually by using build-solaris.sh or 
build-unix.sh. But both of them failed "apxs" from
my apache installation. I didn't install a binary
version of apache. I built it by using:

configure --prefix=/usr/local/apache \
--enable-module=most --enable-shared=max

But that failed on linking from apxs. i.e., didn't
product an mod_jk.so

Re: Precompiled jsp's

[Nikola Milutinovic]

> Why are you pre-compiling the JSP's?
> Doesn't Tomcat do that automatically?

How do you precompile JSPs on startup? I know they can be precompiled if called with 
that "precompile" URL. But suppose I had a lot of JSPs and I would like to tell Tomcat 
to precompile a defined portion of them into run-time servlets, so I could avoid that 
initial lag of first-time-run JSP.

Nix.

Re: File Download - CSV question ****

[Dmitri Colebatch]

Are you using the same client between the two servers?  IE seems to
consider itself more important than mimetypes, and if it sees a file
extension it recognises it treats it as it deems fit, regardless of the
mimetype.  So one possibility is that you have just installed excel or
something on the client, and IE is redirecting the download there.

another option is that the mimetype being sent in tomcat 4.0 is different
to 3.x, but I'm not sure about this, so will let someone else answer this
option.

if you outline exactly what client/server you were using before, and now,
it will make the question more specific.  for intsance, tc3.2 on windows
with a win98 client with IE4.0 and now using tc4.0 on linux with a win2k
client with IE5.0.

how to configure mod_jk for multiple hosts?

[Sebastian Schulz]

hi,

i need information on how to enable loadbalancing in a
one to many scenario (one apache - many tomcats at different
hosts) using apache 1.3.20, tomcat 3.3 and mod_jk.

i successfully enabled loadbalancing on one machine
(different ajp13-workers at the same port), but don't know
exactly how to aply this to differnt hosts.

any suggestions highly appreciated.

thank you all in advance,
basti

p.s.

Launching subprocess under Tomcat as a Service

[Robert Casto]

To all,

I have a servlet that spawns a process to generate PDF reports. When I run
Tomcat 3.2.3 using the startup.bat method, everything works fine. The
subprocess runs, completes its task, and my Servlet returns and completes
its processing. The problem comes when running Tomcat as a service using
jk_nt_service.exe. My Servlet will run, all of my webpages will work, but
when my Servlet spawns the subprocess to generate the PDF file, it hangs. I
have tried changing the settings of the service to log in as various users
with no luck. Any suggestions on how to ensure that the subprocess will
execute while running Tomcat as a service. NOTE: This problem occurs whether
I am using NT4 SP6 or Win2k.

Nope.. That's the idiotish implementation of Threads under Linux. Under
Linux every thread is seen as a process by "ps" so, if you have an
application using 500 threads, "ps" will report 500 processes (this is
because Linux has just one scheduling table for all, unlike real operating
systems which have two, and differentiate between threads and processes).

Short test to prove it, you know how much ram you have in your machine, do a
"ps" and see the amount of Ram used by each single "java" process, sum it
all up, see how much swap space you're using, and "tad" You have more
memory than you thought

Regarding your OutOfMemoryException, when that's thrown in one thread, all
other threads die too, because all threads reside in the same memory space,
so, if one thread doesn't have memory left, so not even the others. (they're
threads, not processes).

Re: Precompiled jsp's

[Thomas Crook]

You need to include the URL to servlet mappings in
your web.xml file. The -webinc switch will generate
the mappings. Here's the command line I use:

jspc -d jsp2java -p com.myco.myapp.jsp -webinc
WEB-INF/jspc.xml -webapp .

After Ant runs the jspc command I have it run a javac
task which places the class files in
WEB-INF/classes/com/myco/myapp/jsp

Then I run a small script to insert the webinc
generated file "jspc.xml" into web.xml

In the server.xml file, you would create an entry like this:

  

with "..." replaced by whatever other attributes you need.  The startup
processing will automatically look for matching property setter methods
(for instance, an attribute "debug" will look for a "setDebug()" method)
in your implementation class.

The class itself needs to be unpacked under $CATALINA_HOME/server/classes,

Re: how to keep form data

[Siomara Pantarotto]

If you do the validation in the client side (using java script) you do not 
lose the information. Besides this is a better approach once you don't want 
your code to do the avalidation in the server side and then post that the 
user made a mistake.

Keep validation in the client side always

File Download - CSV question

I wrote an application that for Tomcat 3.2 running on window. In the HTML
the is a reference (  ) to the filename. 
When I run this on windows I get a popup "save as" selection box.

Is this a difference between TC32 adn TC40 or Unix / Windows.
Is this configurable.

Win2K IIS/Tomcat hangs

[Dan Rasmussen]

Hello,

if (true == repeate message)  
{
Sorry this is a repeat... I just joined the list yesterday
and sent this to the list at the same time but didn't get
confirmation that I joined until this afternoon.  I just
started seeing traffic on the list and I'm afraid that I
might have missed any replies if it did make it to the
list. 
}

I did check the archives and have seen similar postings but
no info that fixes my problem...

I have been attempting to get IIS on Win2K/SP2 to play with
tomcat 3.3.  I have tomcat 3.3 installed and serving up the
Tomcat examples using this url:
http://localhost:8080/examples/jsp/index.html.  

I then used the "Tomcat IIS HowTo" to get IIS setup.  I got
to the point where I get a green up arrow on the filter but
when I try to get at 

http://localhost/examples/jsp/index.html

The browser (exploder 5 or netscape 6.1) just hangs (see
below for the tail of the iis_redirect.log which has a
happy look about it to my untrained eye).  I did the whole
bit with making the jakarta virtual directory and adding
the ISAPI filter.  I don't think I would get this far
otherwise.  

The redirector is a downloaded binary.  I checked the
registry entries.  What else could be wrong?  Is there
something I missed in IIS: Security?, other virtual
directories besides jakarta?.  Suggestions?

I had no problems integrating with Apache on NT and few
with Apache on Solaris.  IIS is a different story :( 

Any help greatly appreciated.

Thanks.

Dan Rasmussen

have set CATALINA_BASE to the dist dir that I built and set
CATALINA_HOME to a different dir that contains "conf", "logs", "webapps"
and "work" dirs (copied from CATALINA_BASE). When I run startup.sh, I
get the output about what environment variables are being used, but no
tomcat is running (no java in ps) and I get the following entry in
$CATALINA_BASE/logs/catalina.out:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/catalina/startup/Bootstrap

If I unset CATALINA_HOME, I can run tomcat ok. However, I would like to
try to get this to work with multiple CATALINA_HOMEs.

When I look at the Bootstrap.java file, in the comments section, it says
something about the server directory being under catalina.home and the
code seems to do it this way to. Did I make a mistake or misunderstand
CATALINA_HOME and CATALINA_BASE? 

For fun, I tried just copying the "server" dir to CATALINA_HOME (even
though that seems at odds with what CATALINA_HOME is for) and that
didn't seem to help. Thanks for any help,

Lloyd

XML ClassCastException and tomcat 4.0 documentation

[Joel P. Worrall]

I am facing a terrible dilemma and in need of accurate information.

I believe my issue deals with the Tomcat 4 class loaders and my problem
surrounds the use of Tomcat 4.0.1 on jdk 1.4 with the JDOM beta 7 jar.

2 scenarios:

1.  unpack tomcat 4, configure the server.xml to look to my webapp.

My application WEB-INF/lib jar contains jdom beta 7 and the latest and
greatest xerces jar (built from source of xml.apache.org).  (Note that we
now have a xerces jar in the CATALINA_HOME/common/lib directory AND my
webapp/WEB-INF/lib directories)

For some reason, despite the fact that both xerces are recent, the following
exception occurs.

javax.servlet.ServletException: Servlet.init() for servlet jsp threw
exception
at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:871)
at
org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:
3267)

java.lang.ClassCastException:

at org.apache.catalina.core.StandardWrapper.load
..

For some reason, the ClassLoader(?) get confused and spits back a that
ClassCastException, claiming that the xerces DocumentBuilderFactory
implementation does not implement the interface - when it clearly does.

2.  Ok, so I remove the xerces.jar from the webapp/WEB-INF/lib directory.

I startup the system.  Now the jspservlet starts fine but my own servlet
that (a few levels deeper) makes a call to org.jdom.input.SAXBuilder chokes
b/c the org.apache.xerces.parsers.SAXParser is being cast to an XMLReader.
Now I checked the xerces.jar's SAXParser class AND IT DOES implement
XMLReader, but it throws the following exception none the less.

This leads me to believe its ClassLoader issue.

My frustration comes in that the documentation (HOWTO on ClassLoader) seems
to be very inaccurate, and I am left wondering how the ClassLoaders work,
what I need to configure to seperate these jars or whatever might be needed.

Someone who knows what they're doing... please help me.  I can (and do)
duplicate the error like clockwork.  I'm certain not to be the only one with
this issue and I hope to contribute the solution / explanation to the
community.

thanks,

Re: JDBC Problem

[James Chuang]

Can't see how this is a tomcat question, but the Oracle connect string
should be:

jdbc:oracle:thin:@::

so using your example, it should be something like:

jdbc.oracle:thin:@hostname:1521:dbname
