Subject: Connection Pooling with different databases problems


Dear all,

I used Tomcat 3.2.1 with Poolman 1.4.1 running on an
iis4 webserver. I have configured Poolman serving 4
databases with the MSSQL server installed on the same
machine. All servlets run well and can get connections
at the beginning, however, general error (from Tomcat
console) and access violation (windows system
alert)occur from time to time which rendered the JVM
(I used sun jdk 1.3.01) and Tomcat died. I already
spend alot of time to fix this but still didnt get any
clues

Thanks

Any instance of Win2K with TOMCAT?

[Sachin Phatak]

Hi! Everybody,
1. Has anyone out there used this combination successfuly - TOMCAT (running
as an NT service), IIS5 on Windows 2000 Server?

2. TOMCAT works fine on port 8080 but when I call the default examples
context, via IIS (i.e. on port 80) I get a 404.
The log files seem to show the redirection (using isapi_redirect.dll) being
executed.
Can anyone suggest a possible cause &/or solution?

3. What do the entries in isapi.log mean?

log file entries:
isapi.log
[jk_uri_worker_map.c (334)]: jk_uri_worker_map_t::uri_worker_map_close, NULL
parameter
[jk_uri_worker_map.c (184)]: In jk_uri_worker_map_t::uri_worker_map_free,
NULL parameters

Are you using JNDI for Driver-Access ? I figured out that this is the
only access-mode in wich poolman isn't corrupting database access from

Tomcat, IIS and virtual hosts

[Robert J. Lebowitz]

I recently installed Tomcat 3.2.1 on an NT 4.0 server running IIS according
to Gil Shachor's directions, using JavaService to install it as an NT
Service.  Everything worked exactly as it supposed to; my JSPs are working
fine.

However, on a separate NT 4.0 server, following the same directions, I've
been unable to get the server to redirect correctly.  I know that Tomcat is
running because I can call up my JSPs and the Tomcat examples using:

http://localhost:8080/examples/jsp/index.html

However, what I really want is to be able to use the URL

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


I realized that primary difference between the two servers is that one runs
virtual hosts.  I suspect that the configuration for Tomcat on IIS must be
different when you have virtual hosts.  I've looked for examples in the
documentation, but haven't found any; most examples seem to be geared for
Apache.  I discovered the  directive for server.xml, but my efforts
at getting it to work failed.

Can someone send me an example of how to configure Tomcat to work with
virtual hosts?

JSP re-compile performance under heavy load

[Jason_Henriksen]

I am considering a design where a thread calls a  long running query, uses
the results to generate a JSP and then write the new JSP over the old JSP.
Tomcat would then notice the update, recompile the JSP and display the new
query results.  The query/rewrite would happen once every 10 minutes.  The
query could take up to a minute to run.

Will tomcat do this acceptably if the server is under heavy load?  If this
would create a performance/memory problem, is there anything in my code
that could be done to minimize it?  Is there any help I could provide in
the Tomcat code to optimize this?  (I've never coded anything for Tomcat,
but I'd love an excuse to get involved)

I know that JSP re-compilation is not generally used as a production
feature.  Could it be reasonably used this way, or am I better off to
examine another avenue?  (Such as holding the results in memory and
re-printing them for each request, which would be memory prohibitive)

Thanks,
   Jason Henriksen

Re: JDBCRealm enhancements

[Peter B. West]

Following Ignacio's suggestion, I checked out the cvs of 3.3 and tested
the message digest password fucntions again.  They are working as (not)
advertised.  Not being familiar with Java or Java security, I am still
not sure of the supported message digest algorithms, but, according to
http://java.sun.com/products/jdk/1.2/docs/guide/security/CryptoSpec.html#AppA,
they include MD5, MD2 and SHA.  I tested MD5.  I wrote a small app to
generate md5 versions of the plaintext passwords in the users table of
my postgresql 7.1 database.

The html howto on JDBCRealm in the distribution is out of date and a bit
misleading.  It documents this entity in server.xml:

 

In 3.3, this entity becomes JDBCRealm, and the className attribute
disappears.  This is documented in the server.xml file.  The howto has
this in the discussion of attributes to the previous entity.

Digest The algorithm used for digest passwords or "No" for plain
passwords, the values can be "MD5", etc... (Optional)

I have used lower-case `digest'; i.e.
digest="MD5"
 
Then there is the following setion on digested passwords.

Using digested passwords

To use digested password you need to store them digested. To achieve
this, you will need to use the same digest strategies that JDBCrealm
uses to store the passwords, inside JDBCRealm there is a static method
with signature final public static String Digest(String password,String
algorithm) this method is provided as a tool to be used outside
JDBCRealm by an application that want to store passwords readable by
JDBCRealm.

Again, the method is all lower case, i.e.
final public static String digest(String password, String algorithm)

Furthermore, there is a main in JDBCRealm.java which allows the class to
be used as an app to generate the digested passwords.  Format is

java org.apache.tomcat.modules.aaa.JDBCRealm -a MD5 passwd1 [passwd2
...]

and the -a argument is your desired algorithm.

Ignacio, I have just put a note in bugzilla.  I have a patchfile for the
howto.  Where should I send it?

Preserving session state from https to http on tomcat

[Ben Wong]

Hi,

I am using form login and I'd like to send my username/password via https to
the server. That can be easily accomplished by setting up the https
connection on port 8443 on tomcat. The problem is after logging in, I'd like
to switch back to http with the user "login state" preserved from the https
session. But alas, switching from https to http wipes out session info on
Netscape (4.7). When my post login jsp pages reference the previously set
session login object via http, null is returned. However, if I stay in
https, everything is fine.

I know bea weblogic has a solution where the server can be set to inhibit
the server port number from being included in the cookie sent back to
Netscape. This way only the domain name is sent. But I can't find that a
similar setting in Tomcat.

Any advice on this would be greatly appreciated.

Thanks

Ben Wong

Fixed Tomcat white pages and no responses problem...for me anyway.

[Rainer Mager]

Hi all,

I know quite a few people have experienced problems with Tomcat such that a
web hit will hang (never return) or give an immediate empty page. These
incidences are somewhat dependant on traffic and when under heavy load seem
to increase. Anyway, we too saw this problem with Tomcat 3.2.x and 3.3.x (we
haven't tried 4.0 yet). Well, for us anyway, we managed to get around this
problem with 3.3.
Basically, I ran Tomcat from within a debugger (Borland JBuilder) and found
that when these errors occur Tomcat didn't seem to be at fault, that is, I
could find no threads doing anything wrong. This, compounded with other
tests, eventually led me to believe the problem was in the communication
from Apache to Tomcat. I tested this by running Tomcat stand-alone and with
Apache (Ajp13) under heavy loads. When running with Apache we could
reproduce the problem within minutes, to the point where the server (the
combination of Apache and Tomcat) was in a state where nearly every second
or third hit had the above problem. When running with Tomcat stand-alone
(running servlets on port 8080) and Apache serving static pages on port 80
we could not reproduce the problem after hours of testing.
Obviously the big problem with this solution is the need to run on
multiple, non-standard, ports. If you have the above problems and can live
with this then you might want to try our solution. Of course you could
alternatively run everything through Tomcat on port 80 but this has its own
limitations.

Today I hope to begin testing these problems with 3.2.2b4 which I have
heard may not have the existing problem. Anyone else with news on this
front?

I don't really know what you're trying to do, but the above looks like
a simple perl problem.  Note that when you define the variables, the
names are $CFC_CFLAGS and $CFC_CFLAGS_SHLIB, while the error messages

Servlet Classloader problems Tomcat 3.2.1

[August Gresens]

I am trying to deploy a servlet in Tomcat 3.2 which uses a 
classloader. I am having problem with the classloader not finding the 
classes I have installed in the WEB-INF/lib directory.

 From other threads, I have discovered that this a configuration issue 
that has to do with the classloader hierarchy.

The solution ( described in a thread called "Re:Servlet Classloader" 
posted on Feb 2nd, 2001 ) describes the work around to the problem, 
which is unclear to me:

"place a copy of the dispatcher servlet into each apps 
WEB-INF/classes directory."

Can anyone tell me what this means? Does anyone know if this problem 
has been addressed in version 4.0 of Tomcat?

Thanks,

August Gresens

TC 3.2.2b4 URI Rewriting with mod_ssl

[Wolle]

I have testet the TC3.2.2b4 now with the ajp13 protocol over the new
mod_jk-eapi.so
and mod_jk-stdapi.so (release 4/30), and nothing will work with URI
Rewriting.
Have I  something more to  do ? set TOMCAT_OPS like below, or to copy

Servlets, Beans, and Threading

[Sean]

Hello All,

If I have a process that needs to run within Tomcat to communicate with a
remote server, and that process needs it's own thread of execution, what
would be the best way to go about this in the Tomcat/Servlet container
world?  I am not sure if each Servlet has it's own thread of execution so I
wasn't sure if I should just subclass Servlet or HttpServlet.  I am not sure
of the ramifications of having a bean manage it's own threads and how that
would effect Tomcat in general.

Does anyone have any pointers, ideas, or suggestions on how they have done
this or would go about doing this nicely in Tomcat?  Would this be cross
container code or Tomcat specific?

Thanks,
Sean

integrating Tomcat with PWS on NT

[Lyle H. Ward]

All,

I'm getting "java.lang.NullPointerException
at org.apache.tomcat.service.JNIEndpointConnector.start(JNIEndpointConne
ctor.java:110)" 

Question 1. Should uriworkermap.properties and uriworkermap.properties-auto
be similar? uriworkermap.properties is set to use jni only and
uriworkermap.properties-auto does not contain any reference to jni. It's
default is ajp12.

Question 2. For an NT installation, does the path separator matter in the
conf files. e.g. in server.xml there is path="logs/tomcat.log" and 




Question 3. The jni_connect.dll appears to be failing to load with a
java.lang.NullPointerException. Any Ideas?

Re: tomcat.log

[Ben Ricker]

You want to turn down the logging level in the server.xml file; if it is 
info, change it to 'warn'. Also, you could use logrotate running at a 
certain time frame to watch the log for a specific size and then "roll 
it". I am not sure what issues this raises with Tomcat alone. With 
apache, you have to HUP it (on Unix).

Hi Christian, I'm writing a document on interceptors at the moment, I can

The TC 3.2.1 JDBC realm is a pretty poor implementation since it is not

Jakarta NT Service

[MAURER,ALEXANDRE (HP-Switzerland,ex1)]

Hi !

My environment : 
NT 4.0 Worksation SP5 192 Mb RAM

I managed to have Tomcat run on my NT notebook, I even managed to connect it
to Apache (well the instructions were very simple and clear). 
Tomcat is running using the startup batch files.

I still have a problem running Tomcat as a NT Service; I downloaded the
jk_nt_service.exe and configured to whole as described in the doc, which
works; well partially : 
- Registery entries are correctly done
- I can hence see the Service using the appropriate Control in the Control
Panel
.. but the service won't start  
net start JK_Tomcat ( the name I gave) results in : 
The JK_Tomcat service is starting.
(working)
The JK_Tomcat service could not be started.

The service did not report an error.

More help is available by typing NET HELPMSG 3534.

My questions are quite simple : 
Is there a way to produce verbose output from jk_nt_service ? 
Is there a place where log information about that can be found ? 

I tried to trace the Registery/File access done by the JVM (only one running
on my system) using some utilities from SysInternals but the JVM is not
started at all (or it does no Registery/File accesses I could trace !).

Thank you for your help

You can also trick it with some JavaScript.  When the user goes back check
to see if there is anything in the browser's forward history (i.e.
history(1) or something like that, I don't remember the exact syntax).  If
there is something in the forward history then just do a
location.href="someurl.jsp" redirect to the page you want them to go to.
That might be a work-around.  Total speculation here because I've never
tried this before, but I don't see why it wouldn't work.

Unsubscribing problem

It seems that is no solution to get out this list, but to change the email

mailto:[EMAIL PROTECTED]  with the unsubscribe in

STATUS: doesn't work

mailto:[EMAIL PROTECTED]
but with my very own data. My emal address is [EMAIL PROTECTED], so I sent
the email at
mailto:[EMAIL PROTECTED]
STATUS: doesn't work


Although, in the welcome message, it was clearly specified that a
confirmation email will be sent back to me, no such thing happened. So I
guess that we're all stuck in here, unless someone has another idea.

Re: GZIP, JSP and servlet

[Cécile QUERAN]

Servlet filters may be a very good idea for my problem.

mod-gzip is used -as far as I know- just to compress files when a .gz
version exists, which means it won't do anything for dynamic content, unless
the dynamic content is output in a file, which is not scalable nor
efficient.

Thanks a lot for your help.

RE: [ERROR] OutputStream is already being used for this request

I do not use pageContext.forward(..) or .include(..)  and there aren't any
<%  written the following code is written in a Servlet:
response.setContentType ("image/GIF");
ServletOutputStream outStream = response.getOutputStream();
int p1 = 1;

stream.RemoteRead(bytes,p1,p2);
outStream.write(bytes);
I thought that they might be some flag which can dim the PrintWriter "out"
and then I could pass the outtputStream to the client side.

-Original Message-
You might need to make sure that no output is being sent to the browser
prior to your attempting to open the outputStream. ANY spaces before the
pageContext.forward(..) or .include(..) call may be sent to the browser and
will create a JspWriter output stream that will conflict with your
getOutputStream() call. One thing worth trying is to start your jsp file
with the first characters "<%", the scriptlet openning tag, and make the
call to the servlet before any output is generated in your jsp file. 
I hope that helps,

tomcat.log

[Georges Boutros]

hi,

i'm testing the durability of tomcat under a heavy attack of users ,

i got a problem with the tomcat.log and jasper.log , those 2 files got so
big they took all the available space on my harddisk

which have failed my test.


does anyone know how to manage the log files not to get so big.

thanks

JDBCRealm changes

[Christian Hargraves]

Hi all,

I sent a message earlier this morning about enhancing JDBCRealm. We are 
going to do this anyways. I think it would be better if we could somehow work 
together and put the changes in the tomcat release. 
Does anyone have anything to say about this? Does anyone care? Is anyone out 
there? I'm beginnig to feel lonely..

Anyways, I would appreciate some form of feedback, even if it's "go to hell 
and leave us alone." 

Thanks,
Christian

I don't really know what you're trying to do, but the above looks like
a simple perl problem.  Note that when you define the variables, the
names are $CFC_CFLAGS and $CFC_CFLAGS_SHLIB, while the error messages
 ^   ^
are for $CFG_CFLAGS and $CFG_CFLAGS_SHLIB.  Looks like a simple typo.

RE: Why Use apache

[Tony Armstrong]

These questions seem to come up a bit. The answer to which server(s) to use
really depends on the situation you are in  e.g.:

1. You want to develop and test JSPs/servlets for yourself - Tomcat is fine,
you do not need to have another server.
2. You already have a production server e.g. IIS and want to add
JSPs/servlets and use Tomcat - well you would have to have a real strong
business case to change from IIS to Apache or another server
3. You have a business plan that incorporates a web server serving static
pages - high load, and has dynamic pages based on JSPs/servlets. This is
probably the hardest decision as it involves many aspects i.e. company
policy, current hardware etc

So the first thing to do is assess your needs, what do you really want. From
this you can narrow down the different scenarios.

One thing to remember, just because apache/tomcat are free (which is great)
there is always a cost involved.

RE: Problem with session tracking. Please help

[Roberts Huw]

Nope.  I have a JSP with only 26 lines (started with about 7 lines but I've
been 
adding more information).
What I'm finding now is that if I shut down my browser and restart it then
the 
result of HttpSession.getId is a new random string.  On the first refresh,
that 
id is also put in the browser cookie as "JSESSIONID".  Some other user
connecting 
from a browser running on a different machine can (not always) then "steal"
my session 
and rewrite HttpSession.getId.  Subsequently the other browser has getId and

JSESSIONID consistent with the new id, and my browser has getId and
JSESSIONID 
inconsistent(!!!) with the getId equal to the new id and JSESSIONID equal to
the old id.

Here's the JSP:

  
  
  Huw's snoop page
  
  

  <%HttpSession ss = request.getSession(true); %>
  SessionId: <%= ss.getId() %>
  IsNew: <%= ss.isNew() ? "true" : "false" %>
  <%Integer i = (Integer)ss.getAttribute("fred");
if (i == null) 
  i = new Integer(0); 
else 
  i = new Integer(i.intValue()+1);
ss.setAttribute("fred", i); 
  %>
  Count: <%= i.toString() %>
  <%Cookie[] cookie = request.getCookies(); %>
  Cookies:
  <%for (int j=0; j
  <%=cookie[j].getName()%> <%=cookie[j].getValue()%>
  <%}%>

  
  


Thanks,
Huw

RE: Tomcat Performance..

[Craig O'Brien]

Hello,

Those are similar numbers to what I have been getting on Intel platforms
with Tomcat3.2.1.  You can boost Tomcat to about 90 pages per second using
ajp13, mod_jk, and reducing the log level to warn rather then info. (of
course your Servlet code makes a difference) There is actually a bug in the
logging with Tomcat 3.2.1 -- info actually gives you debug log level.
According to GOMEZ the ajp13 connector is not fully optimized and mod_jk is
still unfinished.  Apache's performance can be boosted by limiting the
modules that you use and reducing log levels as well.  Interestingly, I was
testing a servlet which displayed date, session variables, and generated a
random password and clocked in at about 88 pages per second with mod_jk.
When I direct connected to Tomcat I was able to get 463 pages per second
with no errors so there is allot of potential there. I was able to top out
at 1107 pages per second on that servlet with Resin. Consider your
bandwidth, of course, 50-60 pages per second can easily overwhelm a T1 line.
Indeed with a standard 45k+ page you would be lucky to anywhere near 25.

Regards,
Craig

  Well, alas I haven't been able to talk the iPlanet folks into building
iWS for me on Solaris x86 yet so I can't test it that way. In testing
just straight normal everyday static HTML serving between Apache and
iPlanet between the two platforms I get a more expected performance
difference. Where the iWS server can spit back something like 200
requests per second and the Apache server can spit back 170 requests per
second. That would be what I expect. I've got a couple of other projects
I've got to get done here today and then I was planning on building the
Apache/Tomcat setup over on the Ultra 60 to see if the performance
numbers are still skewed as much on the same platform.

AW: Why Use apache

[Ralph Einfeldt]

There are some things to add:

- tomcat has to run as root to use a privileged
  port (like 80). Apache just opens the port as 
  root and spawns children under a different
  user id that process the requests.

- there are several modules around that only
  exist for apache (Like mod_gzip, mod_zlog)

- tomcat doesn't support Frontpage Server 
  Extensions (Or other CGI-Packages)
  (Please no flames, I'm not using it, but
   some of our customers)

Summary from previous posts:
- tomcat access logging is not standard
- apache will be faster in serving static content
- apache will be faster in 'speaking' http
- apache 'speaks' HTTP 1.1, tomcat 3.x speaks only 1.0
- apache is more stable
- apache is more secure

So it sounds like you _are_ running into a similar issue as I am: one
browser instance (see below) connecting to one or more servlet containers
running on the same machine.  Right?

IE will only ask once per browser instance (or process): if you start up
another IE (from a desktop icon, for instance), it'll ask again.  But if you
start a new window by selecting "File/New/Window" from the menu, it's the
same browser instance, and you'll share the same session ID; and, if the
original browser window was already connected to your server, IE won't ask
again for the new one.

And note that, if you disable per-session cookies and enable persistent
cookies in your browser, the cookies will now go to disk and be shared among
all browser instances: you'll once again run into servlets clobberring your
cookie, but opening new browser instances won't help you anymore.

Re: mod_jk build on Solaris

I tried updating the apxs perl script with the following:

my $CFG_TARGET= 'q(httpd)';# substituted via
Makefile.tmpl 
my $CFG_CC= 'q(gcc)';# substituted via
Makefile.tmpl
my $CFC_CFLAGS= 'q( -DSOLARIS=260 -DMOD_PERL -DUSE_PERL_SSI

my $CFC_CFLAGS_SHLIB  = 'q(-fPIC -DSHARED_MODULE)';
my $CFG_LD_SHLIB  = 'q(ld)';
my $CFG_LDFLAGS_SHLIB = 'q(-G)';
my $CFG_LIBS_SHLIB= 'q()';
my $CFG_PREFIX= 'q(/usr/apache)';
my $CFG_SBINDIR   = 'q(/usr/apache/bin)';
my $CFG_INCLUDEDIR= 'q(/usr/apache/include)';
my $CFG_LIBEXECDIR= 'q(/usr/apache/libexec)';
my $CFG_SYSCONFDIR= 'q(/usr/apache)';

When executing the script, I now receive the following errors:

Global symbol "$CFG_FLAGS" requires explicit package name at
/usr/apache/bin/apxs line 91.
Global symbol "$CFG_CFLAGS_SHLIB" requires explicit package name at
/usr/apache/bin line 371.

I was unable to copy verbatim the settings that John had mentioned due to
differences in the location of certain apache directories.
Does anyone have an idea why this is failing?

 <<...>> 

some doubts abt precompiling jsps.

[kamesh jayachandran]

Hai all,
As suggested I can precompile the jsps to classes,but the problem is
1)With jspc I am able to parse the jsps to java files.Now I can
compile.But tomcat follows its own naming convention when compiling the
jsps to classes upon request(if it is not precompiled).Shall I have to
follow the conventions in to make tomcat recognize it.But one solution
sugested is 
$./jspc.sh -webxml $TOMCAT_HOME/webapps/urcontext/WEB-INF/web.xml -d
$TOMCAT_HOME/webapps/urcontext/WEB-INF/classes -webapp
$TOMCAT_HOME/webapps/urcontext/

It parses the jsp files in the context "urcontext" to java files to my
classes folder now I have to compile it.

It generates the web.xml file which maps the jsp request to a compile
servlet.
According to my understanding each web application will have one
JSPServlet instance and depending on the request the corresponding pages
will be shown as the output stream of JSPServlet.(This is what I infer
from the extension mapping in the ROOT web.xml file).If I generate the
web.xml which points to each request to each servlet,It will lead to many
servlets instanaces instead of one JSPServlet.

Any other solution .

RE: Problem with session tracking. Please help

[Jan Kester]

I have seen a problem with sessions in the past due to bad program design.
Make sure that your servlets have no members. If so, they would share them between all 
users.

Try to make a simple example first to make sure that you can maintain session state.

Are both the servers running on the same host?  This sounds like a problem
I've run into: since cookies are identified by host, all cookies named
"JSESSIONID" from the same host are considered the same cookie.  

In my case, the servlets are running on different ports on the same machine.
I can't see anything in the cookie spec (RFC 2109) which lets you segregate
cookies by port, so I'm out of luck (and maybe you are, too, if that's what
you're doing).

If this isn't your case, try seeing what Tomcat is putting in the JSESSIONID
cookie.  A cheezy way to do this would be to use IE: in the security
settings for your host, change the cookie settings to "Prompt"; then, when
hitting your site, you'll get an alert from which you can see the cookie
info.

RE: Why Use apache

[Duncan Irvine]

I would suggest that Apache is also more secure - it's been around longer,
and has had more development, thus has had longer to mature.  If you hide
Tomcat behind Apache, then any bugs that may appear in Tomcat's URL parsing
(for example) are less of a worry.

Duncan.

RE: Problem with session tracking. Please help

[Roberts Huw]

Apologies.  A misunderstanding.
I have only one tomcat server.  The "different machines" in question
are different client machines.

Interestingly tomcat doesn't appear to be trying to put anything in
the cookie!!!  I have another page which uses javascript to manipulate
the cookie and (when I switch on your suggested option) IE prompts to 
ask whether I should allow it to store that cookie.  In no other 
circumstance does IE prompt to ask about storing a cookie.

So...  How is tomcat keeping track of my session?
Looks as though I may have to revert to your URL encode suggestion...

Thanks a lot
Huw

  Well, alas I haven't been able to talk the iPlanet folks into building
iWS for me on Solaris x86 yet so I can't test it that way. In testing
just straight normal everyday static HTML serving between Apache and
iPlanet between the two platforms I get a more expected performance
difference. Where the iWS server can spit back something like 200
requests per second and the Apache server can spit back 170 requests per
second. That would be what I expect. I've got a couple of other projects
I've got to get done here today and then I was planning on building the
Apache/Tomcat setup over on the Ultra 60 to see if the performance
numbers are still skewed as much on the same platform.

That said, I use it as a standalone web and servlet server. The primary 
drawback then becomes:

It does NOT keep logs like a "real" webserver. There is nothing to show 
traffic or which is amenable to analysis.

So, for a small site which doesn't care about logs, it's great and a lot 
easier to install, configure, and maintain than in combination with Apache.

Re: ODBC-JDBC ** with JSP ** : 'No suitable driver'

[JFC]

Hello ~

Actually I unzipped the classes12.zip file in 2 directories !
1°  %TOMCAT_HOME%\lib
2°  {my_webbApp}\WEB-INF\classes

Moreover, the classes12.zip file still remains in the %TOMCAT_HOME%/lib 
directory... ^-^

I nevertheless feel like it's still a CLASSPATH or dir problem...
Coz it works fine with a "java {my_MainClassName}" DOS command !

But thanx for your answers !

If you unzipped the file into the WEB-INF/lib directory, then 
you did it in the wrong place.  They should go in the WEB-INF/classes

No really, because Tomcat adds the jar files to the classpath, not the lib 
directory itself. If you unzip the file into the lib directory, it wouldn't 
have any effect because of that.

Re: Newbie problem starting web server.

[jackling]

Thanks for Darrell's advice.
I've tried the method. But the message appear in the TOMSTART.LOG is
minimum:

"Starting tomcat. Check logs/tomcat.log for error messages"

in the logs directory I do have tomcat.log. I saw the modified datetime that
it was created some date ago (I don't know how it was created.) That means,
this tomcat.log is not updated either.

So, I don't know what's wrong

my config again:
ver: Tomcat v3.1
OS: Windows98 (able to run on Win98? No need WinNT/2000, right?)

thanks again,
jackling.

How to host a website at home using tomcat?

[Web master]

Hello,

I would like to know, will it be possible to host more than one website 
using one static IP address using Tomcat or am I asking this question in 
a wrong forum?

Any tips would be greatly appreciated.
Thanks

RE: Problem with session tracking. Please help

[William Kaufman]

Are both the servers running on the same host?  This sounds like a problem
I've run into: since cookies are identified by host, all cookies named
"JSESSIONID" from the same host are considered the same cookie.  

In my case, the servlets are running on different ports on the same machine.
I can't see anything in the cookie spec (RFC 2109) which lets you segregate
cookies by port, so I'm out of luck (and maybe you are, too, if that's what
you're doing).

If this isn't your case, try seeing what Tomcat is putting in the JSESSIONID
cookie.  A cheezy way to do this would be to use IE: in the security
settings for your host, change the cookie settings to "Prompt"; then, when
hitting your site, you'll get an alert from which you can see the cookie
info.

Re: ODBC-JDBC ** with JSP ** : 'No suitable driver'

[JFC]

Ok, I'll try that.
Nevertheless, I already tried to put the developped classtree of 
classes12.zip (oracle.jdbc) in the lib directory (unzipped file), and 
it didn't work properly either. I may guess that renaming the .zip in .jar 
would have the same (non-)effect, wouldn't it ?

RE: tomcat3.2 as NT-Service

[Sadasivakurup, Jiji L.]

There is a known problem
 in JDK
1.3 that affects Java applications being run as Windows NT services. The bug
causes the service to terminate when the currently logged in user logs out.
The simplest way to work around this problem is to use JDK 1.2. If your
application requires JDK 1.3 features then you may want to look into
javaserv  or JavaService
. Users have reported
success with both of these packages but there may be others that work as
well.

Hi,

I have installed Tomcat as NT_Service and I have changed the start mode to
'automatic'.

If I make a reboot, the Service starts and all looks fine.

If I only log out and make a new log in, the Service does not start !

Can anyone help ?

Re: Why Use apache

[Peter Davison]

In a word: "speed".

Tomcat is a java application, which runs in a JVM and because of this it runs
fairly slowly.
Apache is (AFAIK) written in C and runs native, and therefore is a lot 
faster.

RE: Why Use apache

[Mike Braden]

This is a confusing part of Tomcat.

You definitely do not need Apache to use Tomcat.  It works
great by itself (and is easier to use that way).

You would add Apache into the mix for several reasons:

* You want to do something other than Java - Perl, PHP, etc.
* You are already running apache and you want to use Java
* Apache is faster at serving static content (tuned for performance)
  and your site has a heavy amount of traffic for static content
* You don't want to run Tomcat as root to be on port 80.  You
  are concerned about security
* You have a heavy load and want to have more than 1 Tomcat server
  i.e. load balancing multiple TC's behind Apache

Mike.

Well, it's been asked many times, so you can check the archives for
answers.  But basically, Apache is more reliable, more robust, faster,
more flexible, more configurable, etc.  If you're only doing
JSP/servlet stuff, then maybe it would make sense to use Tomcat
standalone, but in general, I think it's much better to use it in
conjunction with Apache (or some web server).

Re: Tomcat Boot: Help!

My script:

# Start/Stop Jakarta Tomcat

# Source function library
. /etc/rc.d/init.d/functions

export PATH=$PATH:/usr/java/jdk1.3.0_02/bin

echo

  restart)
$0 stop
sleep 2
$0 start
;;
  *)
echo "Usage: $0 {start|stop|restart}"
exit 1
esac

exit 0
---

I have used other scripts as well, some that use "su", some that just call
/usr/java/jakarta-tomcat-3.2.1/bin/tomcat.sh...none of them have worked.  I
get the same results every time.  Tomcat appears to start (from reading the
logs) but then mysteriously dies before I can run "ps aux".  The script is
currently in /etc/rc.d/init.d with symbolic links in the various rcx.d
directories pointing to it.  When I run the script from the command line, it
works properly, but not while the system is booting.  What distro are you
using, and what versions of Tomcat, Apache, JDK are you using, if you don't
mind me asking?

TC4 & SSL: Error in SSLServerSocketFactory: initProxy()?

[Philippe Khalife]

Dev environment: Win2K Pro, JDK1.3, TC4 B3, latest JSSE, openssl, apache
1.3.19
I don't have a connector for apache compiled on this platform yet, so I'm
trying  direct SSL on TOMCAT

The JSSE seem to be properly setup: I have the JSSE in the CLASSPATH also
under $JAVA_HOME\jre\lib\ext, and $CATALINA_HOME/server/lib, also registered
the Provider in $JAVA_HOME\jre\lib\security\java.security


Server.xml:

  



I tried both openssl certificates and keytool generated ceritificates.

I tried the code of SSLServerSocketFactory (initProxy) in a test class and
it works fine, with or without Security.addProvider(new
com.sun.net.ssl.internal.ssl.Provider());
So it's not a JVM setup issue. Is there a problem with this JSSE?

So what am I missing?
Your help will be greatly appreciated!!

JDBCRealm enhancements

[Christian Hargraves]

First off. Is JDBCRealm just an example of what can be done or is it meant 
for actual use?

If it's only meant as an example of how to write a RequestInterceptor, then 
don't bother to read on, please just respond and tell me so.

We need to add some functionality to JDBCRealm that I think a lot of other 
people might also be able to use.

The following modifications are:

1) The option to put in the password encode type -- This is for those 
companies that encode the password (I think most do). 
Currently only 'base64' and 'none' are supported. This is done by adding an 
attribute in the server.xml tag in the RequestInterceptor called 
encryptMethod. 
I just used the SecurityTools.base64Decode(password) method to do this.

2) The option of storing the userid as well as the username. -- This is done 
by adding another optional attribute that states the userid column. 
This enables user-role table to be queried against the userid instead of the 
username for those sites that have a lot of users. It also throws the userid 
in the session for those that need the userid throughout the entire 
application.

Please tell me what you think. We already added the functionality so there is 
no work for anyone else to do, but to review the code.

ODBC-JDBC ** with JSP ** : 'No suitable driver'

Sorry if this issue has recently come, I'm new to this mailing list.

Yes it does have cookies enabled.  Supposing I decide to use the

I'm not doing either of these things.

No.  What seems to be happening is that a browser will "steal"
a previously existing session while it is still owned by another
browser.  

I have two machines "A" and "B".  "A" looks at the page and gets
a session id (e.g.)"A1" and isNew() returns true.  "A" then refreshes 
the page a number of times.  session id is still "A1" and isNew()
returns false.  Everything is wonderful.  Browser "B" looks at the page
and gets a session id "B1".  isNew() returns true, but the objects 
attached to it are the objects that were
associated with session "A1".  If "A" then does a refresh then the
session id comes back as "B1" and the objects are the same objects.
>From this point on the two browsers share the session and session id
and the objects attached to the session until the session is timed 
out by tomcat.

Re: Tomcat 4-beta 3: ready for prime time?

[Peter Mutsaers]

But for Tomcat, the beta versions are post-milestone "releases" ???
There have been 5 4.0 milestones (alpha) and now there are beta's, that appear to be 
more advanced and stable than the milestones.

Am I wrong in assuming that 4.0 is closer to a release than 3.3?

Subject: Tomcat 4-beta 3: ready for prime time?



Hello,

A week ago I decided to switch from JRUN to Tomcat for my JSP/Servlet
environment. Naturally I started with the officially released version (3.2).

But, especially in the JSP department I found some bugs and inconveniences,
that have been fixed in later releases (3.3-milestone-x, and also 4.0).

Now I wonder, which version should I use in production? It is a stand-alone
Tomcat site for Intranet, so issues with the connectors to other webservers
are not important.
The site is low-volume (1 request per 10 seconds at prime time) but very
important, thus reliability/stability is vital.

Obviously, although 3.2 is the official release, by browsing through the CVS
logs it looks like the unreleased newer versions are of higher quality.

3.3-milestone-2 doesn't seem to have much advantage compared to version
4.0-beta3, since 4.0 seems closer to a real release (it has gone through 5
milestones already, and now seems very close to the final release after some
betas with relatively minor
changes and fixes).

What do you advice?

Not Found (404)

Hi,

I've mounted Tomcat under Apache's server.

I' had plenty of html pages under a lot of directories under my wwwuser.

When I try to reach those directories, I can't.
Each time I've got this error : Not Found(404)

What can I do ?

Re: Newbie : Help integrating Tomcat with PWS on NT

[Lyle H. Ward]

Keith,

You and I are both working with the same configuration. Mine isn't working
yet either, however our problems are different so maybe swapping experiences
will help.

My green arrow is up. My problem is that the jni_connector has a context
problem. Tomcat was working in stand-alone before trying to integrate with IIS. 
I was waiting for someone to answer your Filter DLLs key question before
doing that entry. IIS in not logging attempts to connect to tomcat contexts.
I think this is due to the jni_connector failing to load. The jni_connector
is failing with a NPE. My tomcat logfiles are: isapi.log, jvm.stdout,
jvm.stderr, servlet.log, and jasper.log. I could try sending you a
screen-shot of my registry entries (off-list) if you think it might help. Or
we could go the other way and you send screen shots of the registry branch
and the MMC panels. Just be sure to send any attachments to me. We aren't
supposed to send attachments to the list.

RE: [ERROR] OutputStream is already being used for this request

[Mark Howell]

Your best bet is to call the servlet directly.  I agree with the other
responders that suggest that using a jsp to dispatch a request to a
servlet that generates a non-html/text/wml/xml document should be avoided.
If you *have* to do so, then your jsp must be setup in an awkward way.

related to your step 3:
> 3. This servlet is called by a jsp which is called from an Html file
>(by the tag: , or pageContext.include|forward(). If
this is the case, then...

All of the proper headers must be sent from the dispatching jsp file
(myJsp.jsp), and none from the servlet.  I believe the jsp file will
always send response headers, and it is definitely an error to commit the
headers twice.

No output can be sent from the jsp file at all prior to dispatching to
the servlet, else a JspWriter might have been opened.  It would then
generate an error.

As an example, create a myJsp.jsp file that has no other characters other 
than:
<% @ page content-type="image/GIF" %>

(again, check the page tag for correct syntax, I still haven't referenced
the cheat sheet)

and coment out the following line in your servlet:
 //response.setContentType ("image/GIF");

The point is, that there are no white spaces that might cause output.
This is an ugly hack, and as another responder suggested, it is easily
broken by somebody putting white space in the file before the
 tag. 

All of that said, you should really consider calling the servlet directly
if at all possible.

in server.xml file of tomcat or httpd.conf? do you mean "error" parameter
for low logging?

do you mean the following parameter from server.xml

First, We are a brokerage firm and approximately 1000 different customers
use our internet branch, and I guess 100 user at most use the web branche
simultaneously. what do you think about parameters for Pooling?
(max_threads, mx_spare_servers, min_spare_servers).

But now, the system has too many processes, when I look at with top or ps
commands.

I do not know how to make this change. But Now system runs under heavy
memory load now, I mean that the system uses some swap memory when the
server has heavy load (when it has about 400 processes, it has 3-5M free
memory, and uses 5-6M swap memory).

this is very critical for us, if you help me it is very appreciated.

RE: Objects in Vector are loosing type

[Joel Parramore]

Well, Endre, comments such as "classloading is totally fucked", while having
a nice kewl sound-bite quality, really don't explain what is going on too
well to someone who hasn't encountered the problem before.

Speaking for myself, I had not seen any sort of explanation on the mailing
list before (haven't done an extensive archive check, admittedly, esp. on
the developer list), nor in the Jakarta FAQs.  Another poster commented that
this item keeps popping up; perhaps making this into a FAQ item would insure
that questions and comments on the topic would assist in preventing this
question from (re)occuring.  (Perhaps a weekly posting of FAQ items would
help as well, but that's another issue.)

Thanks for the explanation, though.  And your English is just fine. :-)

RE: Problem with session tracking. Please help

[William Kaufman]

1) Does your browser have cookies enabled?  If not, you need to rewrite all
your URLs, using HttpServletResponse.encode[Redirect]URL().

2) Are you defining a cookie or URL parameter names "jsessionid"?  That one
is used by Tomcat to keep track of the session, and shouldn't be set by the
servlet.

3) Does HttpSession.getId() keep returning new IDs, and HttpSession.isNew()
keep returning "true" on each call to your servlet?

As for documentation, the servlet spec goes into this stuff.  You can
download it at,

> Hi All,
> 
> We're having a problem with session tracking.
> We are using tomcat pretty much "out of the box", without integrating
> with apache or anything like that.
> We are attaching an attribute to the session which we want (reasonably
> enough) to be "per session".
> We are then sending requests for information to tomcat from several
> different client machines (sometimes logged on as the same 
> user, sometimes
> as different users, sometimes using Netscape, sometimes using 
> IE).  All
> machines are running Windows NT4.0.
> 
> What we are finding is that the Session objects are being 
> indiscriminately
> associated with the servlets.  We are getting the right number of
> session attributes created, but when we refresh the page we find that
> the new request is associated with the wrong session.
> 
> Help?  Is there anything obvious we are missing?  Is there a 
> document on
> how the session management works in tomcat?
> 
> We are using tomcat-3_3-m1

> Thanks a lot,
