Ok, I've had a chance to modify my msql example to work with Oracle. Here's
what I found

1) When using the thin driver, make sure that the SID is actually the SID,
not the TNS name of the service. If you're not sure, open your TNSNames.ora
and look for the service name, it should have a entry (SID = ). Use this
as the SID.
Also try specifying the instance on the connect string as in

jdbc:oracle:thin:myinstance@somehost:1512:mysid

I'm not an oracle DB BTW - sorry if the terminology is wrong.

2) You need to remove the javax.sql.* classes from classes12.zip and rename
to classes12.jar. You also need commons.jar, pool.jar and collections.jar in
your common/lib directory.

Debug. If the driver is loading, the Datasource will be created. When you
hit your JSP, Tomcat will dump Ora errors to stdout. Use
$CATALINA_HOME/bin/catalina.bat run to keep the server running in a console
window to get at this dump.

If you see nothing then you have a classpath/driver not found kind of
problem.

So, try a get it to throw some SQLExceptions - that why we know that you're
at least finding the driver OK.

Keep trying - it does work in the end (honest!)

BTW I'm using TC 4.0.3 LE with JDK 1.4.0-b92 on W2K with classes12.zip
downloaded from OTN yesterday, against Oracle 8i

Re: Tomcat 4 - OpenSSL - IE client certificate works partially

[Ismael Blesa Part]

The problem with homemade digital certificates generated with the 
Keytool is that they are self signed, then IExplorer and other browsers 
does
not trust them and does not let you use it for user authentication. 
However if you make your own CA using openssl and you generates server and
client certificates you will see that it works. You have only to add 
your new CA on the trusted group for IExplorer (similar with other 
browsers).

When you make a connection to a secure server, it returns data about in 
which  CAs it will accepct (which CA, means which client digital 
certificates
signed with the given CAs)

You can also use Thawte test certificates (client  server) but it is 
the same if you use openssl as I describe above.

Please, send me your howto and I will take a look :)

By the way If you use Apache as frontend your setup will work better and 
faster and you will be able to make load balance ;)

Henrik Schultz wrote:

Greetings all...

For those not interested in client certificates at the deep technical
level, this is probably not your favorite cup of tea. Otherwise read on.

Enabling SSL in Tomcat is really no sweat using your own home-made
certificates, thanks to the excellent  HOW-TO. Once you get your root CA
certificate installed in the right places, and a suitable certificate
installed in Tomcat, everything works just fine.

However, creating client certificates that works with IE has (at least for
me) shown to be a real pain. I've experimented for months, and tried
numerous postings on this list, but noone seemed to know the finer details.
It was only recently I had a breakthrough, in that a trial certificate from
Verisign allowed me to compare that and a home-made one, and find the bits
that makes the difference, that is, what it takes for it to be shown on the
selection list in IE when the server asks for a client certificate.
Last night I succeeded. The right combination of keytool and openssl
maneuvres to setup a private CA, finally generated a certificate that
installed without a hitch in IE, and came up when I subsequently connected
to my SSL enabled Tomcat. So far so good.

However there is still one major obstacle ... the server aborts the
connection right away :-

IE tells me:

The page cannot be displayed
The page you are looking for is currently unavailable.
The Web site might be experiencing technical difficulties,
or you may need to adjust your browser settings.

In other words, the usual message that indicates that the server screwed
up, and closed the connection.

Interestingly enough the Verisign certificate works just fine. So there is
apparently still a difference to Tomcat.
Have tried to connect using openssl s_client - works A-OK, also with my
home-made certificate.
Have looked in the tomcat logs to no avail. There is no trace anywhere why
the connection breaks.

So the question to the list is: how would I go by diagnosing this? I
believe that the problem must be related to the SSL container (?) that
responds to the traffic on port 443, and does all the SSL handshaking,
because my application never sees anything.
Just like in Apache there's an error log for all the pages that fail -
isn't there such a log in Tomcat?

Thanks for any input or advice you might have!

PS. If anyone is interested in a writeup or HOW-TO of making client
certificates for Tomcat, let me know. This is certainly tricky stuff!

Where to place pjaf files?

[Mats Palats]

When using pja with tomcat, where should I place the pjaf files (the fonts). 
Should they just be in a system path or some special directory inside the

AW: The best website database!

[Ralph Einfeldt]

Other things I noticed with postgres:
  - If you want 24x7 uptime the vacuum command is a show 
stopper because it optains table locks. So you can't
make updates while the vacuum runs. (Otherwise you risk 
deadlocks)
The latest postgres version has shortened the time
where the lock is hold, but the lock is still there.
  - The last time I tried postgres, it (or the driver) didn't
support alias names in selects.
  - The previous version of postres has a significant
performance degration if you join to many tables. One
of our custumers had joins over 10 to 15 tables and the
performance was horrible, so we had to switch to a commecial
one (MySQL was not an option as the application uses views 
and subselects, Firebird was not ready). Haven't tried the
current version.

 tomorrow to see if I did anything stupid, but the only difference seems

 DBCP between 4.1.3 and 4.1.6.

It is easy to replace the DBCP included with another version or a new 
nightly if there is a problem (just replace commons-dbcp.jar in common/lib).

In the case of 4.1.6, some last minute changes were integrated in DBCP, 
so maybe there was some regression.

 computers and different instituon by using servlets an JSP. For
 this purpose, I want to send a parameter to this remote databases
 using an HTML form. And I want to receive all responds and serve
 them in a HTML page to client. How can I do that?

of course, all you need is a class for handing your databases. make
different instances for different dbs and query them. Or let a
another class do it.. The request should not take too long,
as you have a max. response time für your http request..

Virtual hosts/Tomcat403/Apache2039/mod_jk

[Rupert Young]

After many days, I've got it cracked, so I thought this might help.

I am trying to set up a virtual host so that I can use the URL
bliss.mydomain.org (without any suffix), which will serve static and dynamic
(.jsp) files.

Here's what I did.

I used this guide, http://www.webmasterbase.com/article/305 to set things
up, except for the Include statement. I put the auto-generated (which I
don't think are quite right) directives, slightly edited, into httpd.conf
manually.

To the httpd.conf I added, at the end,

IfModule !mod_jk.c
  LoadModule jk_module c:/Apache/Apache2/modules/mod_jk.dll
/IfModule
JkWorkersFile c:/Apache/Tomcat/conf/jk/workers.properties
JkLogFile c:/Apache/Tomcat/logs/mod_jk.log

JkLogLevel debug

JkMount /examples ajp13
JkMount /examples/* ajp13

VirtualHost *
ServerName eai.mydomain.org
DocumentRoot C:/Apache/Apache2/htdocs/webdocs
/VirtualHost

VirtualHost *
ServerName web.mydomain.org
DocumentRoot C:/Apache/Apache2/htdocs/webdocs/web
ErrorLog logs/web-error.log
TransferLog logs/web-access.log
/VirtualHost

VirtualHost *
ServerName bliss.mydomain.org
JkMount /* ajp13
/VirtualHost

The first two hosts are static only (unless they have /examples context).
The bliss host will serve any dynamic files in its base directory.  The
corresponding Host directive in server.xml is,

Host name=bliss.mydomain.org debug=3 appBase=myapps
unpackWARs=true
Listener className=org.apache.ajp.tomcat4.config.ApacheConfig
append=true /
Valve className=org.apache.catalina.valves.AccessLogValve
 directory=logs  prefix=mybliss_access_log.
suffix=.txt
 pattern=common/

Logger className=org.apache.catalina.logger.FileLogger
 directory=logs  prefix=mybliss_log. suffix=.txt
timestamp=true/

Context path= docBase=ROOT debug=0/
/Host


the files for the bliss app are in tomcat/myapps/ROOT.  Hooray !

So I can give the URL http://bliss.mydomain.org/ and index.jsp (by
redirecting from index.html) will be served by tomcat automatically.

The host names, of course, must be set up in a DNS server.

Hope this helps.
Regards,
Rupert

Re: Tomcat 4 - OpenSSL - IE client certificate works partially

[Henrik Schultz]

Peter wrote:

this pretty much sounds like the same problem I was experiencing and
posted earlier today. Sadly, your link below only gives hints on how
to intall a SERVER certificate, but not on how to configure everything
to ask for a CLIENT cert.

This is what I found too. However, the ImportKey program sounds like
a nifty little thing that could come in handy. Thanks for the link
Schwarz!

The few other responses I got to my first posting were along the same
lines, so for the sake of making sure everybody understands this
correctly, let me reiterate:

This is about CLIENT certificates.
Apparently Tomcat gives up mysteriously when receiving a home-made
certificate (perhaps the thread dies or something), but in any case
the connection is quietly closed with no trace or log messages
to be found anywhere.

I have exactly the same problem where the
initial handshake with the exchange of the SERVER cert is just fine,
but then the connection breaks leaving you with absolutely NO
LOG-entry as to why it broke 

Ok, so I'm not the only having this problem, that's assuring... somehow ;-)

So far, I was only able to get an error-message out of Netscape (6.x)
saying unknown SSL Error -12227

I tried to use NS too to find out more, but I had some problems with the
firewall I'm behind to get to my server, so I never got to it.
Unknown SSL error ... Hmm!

Would it make sense to post this on the tomcat-development-list?

I think so. Regardless of why our own certificates does not work, it
is highly problematic that there are no trace of what goes wrong
anywhere.
Do you have experience in this, or do you have the FAQ handy?
I've never tried this myself, but one time has to be the first
I guess :-)

Hi,
try the following two urls, you can find a binary version of mod_jk for
apache 2.0.39 in the first page, and the deploy instructions in the second
page.
http://www.acg-gmbh.de/mod_jk/
http://www.cnr.berkeley.edu/~salazar/apache_tomcat.html

for a slight modification for the deployment, I just include the auto
generated jk config file in the end of httpd.conf instead of copy the entire
config lines into it, and it works, but you need to add a special line in
the server.xml in order to indicate the abosulute path of the mod_jk.dll.

here is a sample:
httpd.conf:
at the end add the following line
Include D:/WEB/tomcat/4.04/conf/auto/mod_jk.conf

server.xml:
Server port=8005 shutdown=SHUTDOWN debug=0
   Listener className=org.apache.ajp.tomcat4.config.ApacheConfig
modJk=D:/WEB/Apache2/modules/mod_jk.so /
   ...
   ...

Performance problems with tc4.0.4 and custom tags

[Timo Carl]

Hello,

We try to upgrade our setup from tomcat3.2.1/jdk1.2 to
tomcat4.0.4/jdk1.4.
There were some major performance problems on our jsp Pages that use
100+ custom tags.
I've already read some other threads adressing this problem.

But I wonder why tomcat3.2 with jasper1 does not have any problems, but
tomcat4. 
Any ideas?

Has anyone experiences with using tomcat4.0.4/jasper2 in a productive
environment?
Is it stable enough?

Thanks in advance,
Timo Carl

expired beans in expired sessions block new sessions? TC 3.3.x

[Power-Netz \(Schwarz\)]

Hi,

i wonder about this behavior:

1. Login in my site via a login bean ( self made )

login.jsp
...
jsp:useBean id=login scope=session class=web.Login/

if (login.valid()) {
%jsp:forward page=prozesse.jsp/%
}
...
login Form  target - login2.jsp
...

This works great as long as the session is valid.

2. The session times out and the login.jsp is forwarded from any page which
detects
that the login is no longer valid.

3. the login pages shows up and I enter the data , but the jsp can't connect
to the database
until the session is directly invalidated with session.invalidate();

4. stdout.log shows this

Tomcat 4.0.4, jndi, jdbc and postgresql [long]

[Przemyslaw Kowalczyk]

Hi

I've just started to write servlets. Servlets that only do processing, without 
connecting to database work fine, but I have some problems to get the 
connection with postgresql via jdbc work.

Tomcat: 4.0.4   (on linux)
Postgresql: 7.2.1 (on linux)
Jdbc: pgjdbc2.jar (from jdbc.postgresql.org)

The servlet is quite simple:

import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class InfoServlet extends HttpServlet {

Connection con;
private boolean conFree = true;

public void init() throws ServletException {
try  {
Context initCtx = new InitialContext();
Context envCtx = 
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open connection 
to database:  + ex.getMessage());
}
}

public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}

public void doGet (HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {

HttpSession session = request.getSession();

// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();

// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}

in web/WEB-INF/web.xml I defined:


!DOCTYPE web-app

And in server.xml in the contex of the application:

I've tried a few different driverName parameters: (restarting Tomcat after 
each change)
jdbc:postgresql://localhost/public
jdbc:postgresql://full.server.name/public
jdbc:postgresql:public
jdbc:postgresql://localhost/

But, despite the parameters, I always get the following error:

exception 
javax.servlet.ServletException: Couldn't open connection to database: 
Exception creating DataSource: org.hsql.jdbcDriver
at InfoServlet.init(Unknown Source)
at javax.servlet.GenericServlet.init(GenericServlet.java:258)
at 
org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:918)


{cut}

I have no idea why Tomcat wants to connect using hsql driver. I grepped 
through tomcat directory and found only one reference to this driver (in 
examples section). I removed event the sample section, restarted Tomcat but 
it didn't help. 

Does anyone know what is wrong?

Przem

Re: TomCat 3.2.3 not respond suddenly.

[TEOH KANG YIH]

Hi TomCat user,

Remember I post this question 1 week ago and there is no feedback from you all?  
However, I have found out further information as follows:

1. Port 8080 still can be telneted in
2. Other JSP files still can be accessed 

These 2 important tell us that TomCat is still functioning!  Only it can't talk to 
Oracle Database, until I restart TomCat.

In order to refresh you, TomCat 3.2.3 runs on Solaris 8.

Any idea or experience with this, kindly share with me.

Thanks.

Where can I find SCO binaries for Tomcat

[will]

Hi,

I have been using tomcat for a little while now, on Linux
and Win2K and love it to bits. I have a need to run it on
a SCO Openserver box, and I have been trying to locate
some binaries for it.

I checked the archives and found some references to a
3.0.3 binary, but was unable to locate it. Could any one
point me in the right direction? I would prefer a 4.0.3
binary but will take what is available.

I was thinking of building it, but taking a look at the
build help file fills me with dread.

Regards,

Wm.

here is part of my server.xml

Host name=localhost debug=0 appBase=..\webs unpackWARs=true
where ..\webs is the root for my iis,

and geomemory is a sub directory under ..\webs

thank you

AW: TomCat 3.2.3 not respond suddenly.

[Ralph Einfeldt]

If there is no error message in the logs, I guess 
it's a deadlock in the database.

Can you provide more info about the jsp that hangs ?

Try a kill -QUIT tomcat pid and have a look at the
stacktrace to see where the threads are.

Have a look at the oracle console (can't remember the name
of the management console for oracle, it's too long ago
that I used it) to find out which connections and statements 
are open.

Re: Performance problems with tc4.0.4 and custom tags

[peter lin]

I've been doing performance benchmarks and profiling of jasper2 with
4.0.3 and most indications tell me it's getting real close to release. 
Several tremendous improvements in jasper2 result in better CPU and
memory utilization. GC is now under control and scales well to 64
concurrent connections w/o any problems. On systems with more memory and
multiple CPU's, the performance should be even better.

The improvements I see in my profiling is speed and consistency. when I
profiled jasper1 with tomcat 4.0.3, the cpu and memory utilization
fluctuated wildly, causing unusually high variance in response time. GC
was horrible for pages with 100+ JSTL tags under 8+ concurrent
connections on a weak system.

I'm not recommending anyone use it in production, but my personal
feeling is it is getting very close to release quality.

AFAIK the main error is in the jdk 1.3 and 1.4. 
jasper2 just contains (beside other changes) a workaround for 
this bugs.

RE: Performance problems with tc4.0.4 and custom tags

[Reynir Hübner]

I have been playing a little bit around with jasper2 as released with tc 4.1.6 and I 
am haveing problems. 

I am using the OSCache taglibrary, and for some reason this does not work as it 
should. I cannot technically describe the problem, as I have not dug into it, but the 
tags are returning wrong values from cache. I think this has something to do with the 
tagpooling feature as this was not a problem in tc.4.1.3 version of jasper 2.

just wanted to bounce that of to somewhere. hopefully someone will pick this up, and 
check what's going wrong.

RE: Tomcat 4.0.4, jndi, jdbc and postgresql [long]

[Les Hughes]

Two things,

In your server.xml
user I think should be username
and
driverName has been deprecated in favour of url which needs the servername
and DB name as well
(as in something like jdbc:postgresql://full.server.name/mybookdb - or
whatever the DB is called)

Are you *sure* you're using the right install of TC and that the server.xml
has no reference to the hsql driver?

BTW - only got this working with Oracle and mySQL so most of this is
guesswork based on those two exercises. 

Bye,

Les
P.S. You shouldn't open the connection in init() nor cache the connection
BTW - use a pool instead :)

Re: Performance problems with tc4.0.4 and custom tags

[peter lin]

have you tried the jakarta cache tag?  Perhaps try it with that first.
It could be the taglib is not compliant with JSP1.2. Also, I notice
OSCache tag examples use scriptlets.  If I remember correctly from
discussion on tomcat-dev, tagpooling should be used only if the tag body
doesn't contain scriplets.  You should ask Remy or Kin-man to get the
authorative answer.

 We are running Tomcat 3.3.1 in standalone mode (no Apache etc) 
 and log requestes to AccessLog with AccessLogInterceptor.
 Unless we misconfigured something it seems like PUT 
 requests only show up in the log if they produced an error
 (404, 500).  Is this a configuration problem or is there
 something wrong with AccessLogInterceptor?

 AFAIK the main error is in the jdk 1.3 and 1.4.
 jasper2 just contains (beside other changes) a workaround for

 Have a look at this links: (Require login)

 http://developer.java.sun.com/developer/bugParade/bugs/4697245.html
I can acknowledge these bug reports. I've seen a significantly higher
memory usage. Additionally, the compiled jsp needs up to 20 sec to come
up. On jdk1.2 it came up within 1 second.

So, what do you propose me to do:
- wait for tc4.1 release (when can we exspect it: July,August or more?)
- play around with jasper2 on production system
- start with jdk1.2 and tomcat4.0

I'm a little bit confused what to decide now.

Re: Persistence Manager choice...

Anyway, I have tried Torque (part of the turbine project) and it looks
fairly
complete.
I have looked at the various mailing lists concerning castor and many
people are
complaining about its performance, that's why I've been directed to
Torque.

Torque has also a very nice tool that will generated the classes, sql
scripts, etc from an
existent database (in my case it was Oracle).

I believe if the body contains only tags, it will use tagpooling. You

RE: querying remote databases

[Turner, John]

All you have to do is write a servlet to do this.  You are confusing
databases with web pages.  It doesn't matter where the database is...if it
is available on the network and you have a valid user account on that
database, then a servlet can connect to it.

If a servlet is running on machine A, and the database is on machine B, the
servlet can connect to the database.  So, in your doPost() method of your
servlet, accept the parameters of your Form, make your connection to the
database, get your results back, format your results, and then send them
back to the requester.  You will want to implement/extend HttpServlet when
you write your servlet.

Hi there


I had some problems using the DBCP connection pool with 4.1.6 and the MS SQL Server JDBC drivers. I couldn't get the pool to use the user parameter specified in server.xml, I ended up having to include the username and password as part of the JDBC URL.

Oh, I've never used the built-in connection pooling before, so I can't speak for 4.1.3. What's happening with your 4.1.6 setup??

 tomorrow to see if I did anything stupid, but the only difference seems 
 to be the tomcat version, so it would follow that something broke in 
 DBCP between 4.1.3 and 4.1.6.


It is easy to replace the DBCP included with another version or a new 
nightly if there is a problem (just replace commons-dbcp.jar in common/lib).


In the case of 4.1.6, some last minute changes were integrated in DBCP, 
so maybe there was some regression.

Hi,

i am one of the guys trying to get a valid MysqlDataSource reference via

the reason is, i cant debug JNDI too good, cause i am no expert in it..)

i have the following:

i placed the mysql mm jar into commons/lib

When i run a servlet with the standard lookup code:
 try {
 javax.naming.Context jndictx = new InitialContext();
 if (jndictx == null) throw new Exception(Boom - No Context);

 DataSource ds =
 (DataSource) jndictx.lookup(java:comp/env/jdbc/TestDB);
 if (ds != null) {
[..]

i get no exception but i also dont get any reference returned from lookup.

I read tons of websites including the tomcat JNDI howto, without beeing able to 
understand it
better (in fact it gets worse cause of thousands of combinations in the web for 
server.xml and
web.xml)

When i leave out factory in the server.xml, i get a tyrex exception regarding loading 
a factory...

I just thought that using a datasource is better than just calling the DriverManager, 
but the
effort seems amazing... or i am too unclever... whatever...

thx for help.

RE: Error with Oracle Jdbc

[Les Hughes]

If you're using a client install of oracle instead of the thin drivers (I'm
guessing because of your @TOMCATDB syntax) then the url is
jdbc:oracle:oci8:user/passwd@TNSname ie

jdbc:oracle:oci8:spifdogg/spifdogg@TOMCATDB
or
jdbc:oracle:oci8:@TOMCATDB and passs the user and password into the
getConnection call.

But for any non-trival system, you should be using a connection pool (search
the archives for a HowTo)

AW: AW: Performance problems with tc4.0.4 and custom tags

[Ralph Einfeldt]

I think you have to (stress-)test which combination is best for your 
environment and application.

I would test them in this order: 

- jdk1.2 + tc4.0
- jdk1.4 + tc4.0 + jasper2
- jdk1.4 + tc4.1

This is more a feeling than a rational decision driven by facts, as 
we don't have tomcat in production and currently don't use tags at 
all)

Depends a bit on the scale when you have to use the environment 
online.

 So, what do you propose me to do:
 - wait for tc4.1 release (when can we exspect it: July,August 
 or more?)
 - play around with jasper2 on production system
 - start with jdk1.2 and tomcat4.0

 Subject: plain MySQL DataSource in Tomcat (i know, damn topic)
 
 
 Hi,
 
 i am one of the guys trying to get a valid MysqlDataSource 
 reference via
 JNDI. But i am getting crazy without knowing where the 
 problem is (perhaps
 the reason is, i cant debug JNDI too good, cause i am no 
 expert in it..)
 
 i have the following:
 
 server.xml

 i placed the mysql mm jar into commons/lib
 
 When i run a servlet with the standard lookup code:
  try {
  javax.naming.Context jndictx = new InitialContext();
  if (jndictx == null) throw new Exception(Boom - No 
 Context);
 
  DataSource ds =
  (DataSource) 
 jndictx.lookup(java:comp/env/jdbc/TestDB);
  if (ds != null) {
 [..]
 
 i get no exception but i also dont get any reference returned 
 from lookup.
 
 I read tons of websites including the tomcat JNDI howto, 
 without beeing able to understand it
 better (in fact it gets worse cause of thousands of 
 combinations in the web for server.xml and
 web.xml)
 
 When i leave out factory in the server.xml, i get a tyrex 
 exception regarding loading a factory...
 
 I just thought that using a datasource is better than just 
 calling the DriverManager, but the
 effort seems amazing... or i am too unclever... whatever...
 
 thx for help.

 I have been playing a little bit around with jasper2 as released with tc 4.1.6 and I

 I am using the OSCache taglibrary, and for some reason this does not work as it 
should. I cannot technically describe the problem, as I have not dug into it, but the 
tags are returning wrong values from cache. I think this has something to do with the 
tagpooling feature as this was not a problem in tc.4.1.3 version of jasper 2.
 
 just wanted to bounce that of to somewhere. hopefully someone will pick this up, and 
check what's going wrong.

All the tags which behaved bad with tagpooling in Jasper 2 have so far 
been proven to be non-compliant, so it's unlikely to be caused by a bug 
in Jasper. In the defense of the tag authors, I have to add that the 
example tag from the examples webapp distributed with Tomcat, as well as 
two of the custom tags from the admin webapp, were also non-compliant. 
So there will probably be a lot of tags which will cause problems.

You can disable tagpooling in the case you can't easily fix the tag.

Hi,

Does anybody know of any good websites/pages that explains step-by-step how
to integrate Tomcat and Apache? I'm using Tomcat 4.0.4 and Apache 2.0.39 on
Windows 2000. I already tried the tutorial at
http://www.webmasterbase.com/article/305 but it didn't work maybe because
that tutorial was for Tomcat 4.0.3 and not 4.0.4. Should it matter? Well, if
anybody knows any other sites, please let me know.

Hi

I've just started to write servlets. Servlets that only do processing, without 
connecting to database work fine, but I have some problems to get the 
connection with postgresql via jdbc work.

Tomcat: 4.0.4   (on linux)
Postgresql: 7.2.1 (on linux)
Jdbc: pgjdbc2.jar (from jdbc.postgresql.org)

The servlet is quite simple:

import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class InfoServlet extends HttpServlet {

Connection con;
private boolean conFree = true;

public void init() throws ServletException {
try  {
Context initCtx = new InitialContext();
Context envCtx = 
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open connection 
to database:  + ex.getMessage());
}
}

public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}

public void doGet (HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {

HttpSession session = request.getSession();

// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();

// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}

in web/WEB-INF/web.xml I defined:

And in server.xml in the contex of the application:

I've tried a few different driverName parameters: (restarting Tomcat after 
each change)
jdbc:postgresql://localhost/public
jdbc:postgresql://full.server.name/public
jdbc:postgresql:public
jdbc:postgresql://localhost/

But, despite the parameters, I always get the following error:

exception

Only one message in digests?

[Henrik Schultz]

Is it just me, or do the rest of you also get only one message following
the index in your digests?
Same thing when requesting a range of messages to be sent to me, only the
first message is returned.
Could it be a problem with our Notes Domino mail gateway perhaps?

R: application Context within a TagLib

[Alessio Fiore]

Hi, there is difference between context attributes and context init
parameters...

Context attributes are managed with setAttribute and getAttribute
methods.
Init parameters are defined in the web.xml file and are read with
getInitParameter method.

Then, you should modify your code in following way:

pageContext.out().print(pageContext.getServletContext().getInitParameter(se
rver_pfad));

You are right, there is a misseling, but correcting it didn't help much :-(

I'm still curious why tomcat wants a hsql driver even though it's not 
mentioned in any configuration file.

RE: Tomcat 4 - OpenSSL - IE client certificate works partially

[Adam Greene]

I don't know if this applies to Apache Tomcat, but Apache Web Server does
not like IE certs.  There was an article in Eweek that talked about how
Apache follows the standard, and Microsoft (as usual) innovated in regards
to SSL, TLS, etc.  So that Internet Explorer does work quite right with
Apache Web Server.  This might be what you are seeing.  Verisign must have
broken their certs to work with both IIS and Apache.

Greetings all...

For those not interested in client certificates at the deep technical
level, this is probably not your favorite cup of tea. Otherwise read on.

Enabling SSL in Tomcat is really no sweat using your own home-made
certificates, thanks to the excellent  HOW-TO. Once you get your root CA
certificate installed in the right places, and a suitable certificate
installed in Tomcat, everything works just fine.

However, creating client certificates that works with IE has (at least for
me) shown to be a real pain. I've experimented for months, and tried

believe that the problem must be related to the SSL container (?) that
responds to the traffic on port 443, and does all the SSL handshaking,

I would absolutely love a HOW-TO.  I have a project that is going to require
certs for security.  I will ultimately have to use a Verisign or Thawte
cert, but I can certainly test with the homemade ones.  Also, have you tried
to get Netscape or Mozilla to work??

Greetings all...

For those not interested in client certificates at the deep technical
level, this is probably not your favorite cup of tea. Otherwise read on.

Enabling SSL in Tomcat is really no sweat using your own home-made
certificates, thanks to the excellent  HOW-TO. Once you get your root CA
certificate installed in the right places, and a suitable certificate
installed in Tomcat, everything works just fine.

However, creating client certificates that works with IE has (at least for
me) shown to be a real pain. I've experimented for months, and tried
numerous postings on this list, but noone seemed to know the finer details.

RE: Tomcat 4 - OpenSSL - IE client certificate works partially

[Henrik Schultz]

You could also use a temporary Verisign certificate to test with, which is
what I have done so far.

No, I did not try Netscape myself due to a proxy issue, but someone else on
th list did that, and that came up with a strange error:
unknown SSL Error -12227
Have still no clue what this is. At least NS is saying something, contrary
to IE that just gives me that bloody Page cannot be displayed.

When I've gotten it all to work I'll write up a HOW-TO. Promise. Enough
people have been struggling with this now for way too long.

 The description is missing (but I dont have a DTD to had to tell whether

Neither adding description nor removing slashes helped.
I've checked the path in manual:

I wonder if there is a way to debug what exactly Tomcat does. What section of

Does anyone tried to connect to postgresql and succeeded?

Hi

I've just started to write servlets. Servlets that only do processing, without 
connecting to database work fine, but I have some problems to get the 
connection with postgresql via jdbc work.

Tomcat: 4.0.4   (on linux)
Postgresql: 7.2.1 (on linux)
Jdbc: pgjdbc2.jar (from jdbc.postgresql.org)

The servlet is quite simple:

import java.io.*;
import java.util.*;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class InfoServlet extends HttpServlet {

Connection con;
private boolean conFree = true;

public void init() throws ServletException {
try  {
Context initCtx = new InitialContext();
Context envCtx = 
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open connection 
to database:  + ex.getMessage());
}
}

public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}

public void doGet (HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {

HttpSession session = request.getSession();

// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();

// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}

in web/WEB-INF/web.xml I defined:

I struggled for weeks (on and off) trying to figure out why Tyrex ALWAYS 
tries to load the hsql driver - in vain.

Don't bother trying to get Tyrex to work - it just doesn't! (And neither 
does it pool connections) - you should try TC 4.1, which uses the 
jakarta-commons DBCP. DBCP works, and pools connections!

apache-tomcat: localhost/examples/ ok, but not locahost/examples

[Ralph Grove]

I've installed tomcat 4.0.4 along with the webapp connector and have 
modified the Apache config (as follows) to relay certain requests to tomcat.

# make connection to tomcat
LoadModule webapp_module modules/mod_webapp.so
AddModule mod_webapp.c
WebAppConnection warpConnection warp localhost:8008
WebAppDeploy examples warpConnection /examples

Now, apache forwards requests to tomcat only when the URL ends with a 
'/'. When I request the URL http://localhost/examples, for example, the 
server response Not Found, but it correctly processes 
http://localhost/examples/ .

Thanks for any help or suggestions.

Yes, without any problems from 'standalone' application. I'm able to query and 
update database, so parameters (url, username and password) are ok.

There is no postgresql.jar, only pgjdbc2.jar. I put it in ${tomcat-root}/lib 
directory.  I tried first to add a link named postgresql.jar and then I've 
renamed it but it didn't help :-(

 Do you have a file named hsql.jar? Can you remove it?

I don't have such file.

 Hi, there is difference between context attributes and context init
 parameters...

 Context attributes are managed with setAttribute and getAttribute
 methods.
 Init parameters are defined in the web.xml file and are read with
 getInitParameter method.

 Then, you should modify your code in following way:


pageContext.out().print(pageContext.getServletContext().getInitParameter(se
 rver_pfad));

RE: Tomcat 4.0.4, jndi, jdbc and postgresql [long]

[Les Hughes]

Ok. Summary time.

Martin reflects my experience - I dumped tyrex and used DBCP as well. But
aren't we trying to go direct without a pool? Having said that I've only
ever managed to get datasources working when DBCP is being used...

Check that your driver jarfile does not contain the javax.sql extension
classes. If it does, delete them and rejar. Some versions of Tomcat will
ignore any jar that has these classes present. Be careful with this thought
- I work with jdk1.4 which has these built in.

Also, you don't specify a DataSourceFactory in your server.xml - see below.


Here's a known (well as far as I know...) good postgres solution using DBCP.
See
http://marc.theaimsgroup.com/?l=tomcat-userm=102225547106556w=2
for my original mysql post as well.

 There is no postgresql.jar, only pgjdbc2.jar. I put it in

The problem is that the TC-4.1.6 Admin web-app adds a user ,not a username parameter when you add a DataSource resource.

 Oh, I've never used the built-in connection pooling before, so I can't

DBCP expects the user to be identified by a parameter called username,

R: taglibs and application context

[Alessio Fiore]

Hi Andreas,

the problem is that you put an attribute in the request and then you get it
from the  context... you should, instead, get it from the request, so:

request.setAttribute(Constants.VARIABLE_KEY, variable);

...

variable =
(String)pageContext.getRequest().getAttribute(Constants.VARIABLE_KEY);

Alessio

the variable is null

Waht's wrong?

plain MySQL DataSource in Tomcat (i know, damn topic)

[Marc Logemann]

Hi,

i figured out how to use the default DataSource with MySQL:

Resource name=jdbc/mysql auth=Container type=javax.sql.DataSource/
ResourceParams name=jdbc/mysql
parameter nameuser/namevalueroot/value /parameter
parameter namepassword/namevalue/value /parameter
parameter 
namedriverClassName/namevalueorg.gjt.mm.mysql.Driver/value/parameter
parameter namedriverName/namevaluejdbc:mysql://localhost/maxbahr/value 
/parameter
/ResourceParams

But i wonder how i can use the MysqlDataSource class and i wonder where is the real 
need to
use the MysqlDataSource class.

With this scenario however, is there a connection pooling implied? For me it seems that
when i do DataSource.getConnection() i just get a normal MySQL connection as when i do
classForName(Driver) or?

Updating files without restarting Tomcat

[cbarnes]

I am using Tomcat 4.

I have a number of properties files in the WEB-INF/classes directory. I need
to be able to change the values of the properties in these files, but it
looks as though I need to restart Tomcat every time I change a value in
order for it to recognise the new version of the file. Is there any
configuration I can change so that it is not necessary to restart Tomcat
when I change the values of the properties. Is it possible for this to apply
just to specified files - I don't want it to check the status of all the
files in WEB-INF/classes because I know the class files won't change.

Thanks,
Catharine

RE: plain MySQL DataSource in Tomcat (i know, damn topic)

[Clay Graham]

Are alot of people having problems with the mySql drivers or am I being 
myopic...

i tried to do this with STRUTS datasource pooling and had the following 
issues...

I am asking a question because I am very suprised at an unexepected 
behaviour and thought that someone may have a hint.

I have linux 7.1 tomcat 404 ant struts 102 working and they have been 
tested, and I am taking the next step by starting to connect to my MySql 
database, all goodness.

So my first step was to add the datasource in my struts-config.xml as 
follows:

data-sources
  data-source
set-property property=autoCommit
  value=false/
set-property property=description
  value=The Test Datasource/
set-property property=driverClass
  value=org.gjt.mm.mysql.Driver/
set-property property=maxCount
  value=4/
set-property property=minCount
  value=2/
set-property property=password
  value=/
set-property property=url
  value=jdbc:mysql://localhost/test/
set-property property=user
  value=root/
  /data-source
/data-sources

the next step was to add the mm.mysql-2.0.6.1.jar to my project's 
WEB-INF/lib directory, the standard approach

[clay@meis test]$ jar -tvf test.war|grep mm.mysql
390333 Sun Jun 30 16:20:20 PDT 2002 WEB-INF/lib/mm.mysql-2.0.6.1.jar

I am sure this JAR has the mysql driver in it:

[clay@meis test]$ jar -tvf web/WEB-INF/lib/mm.mysql-2.0.6.1.jar |grep 
Driver
 15163 Sat Jun 16 09:20:28 PDT 2001 
mm.mysql-2.0.6/org/gjt/mm/mysql/Driver.java
  5443 Sat Jun 16 09:20:28 PDT 2001 
mm.mysql-2.0.6/org/gjt/mm/mysql/Driver.class

so when I install the application using ant the following error occurs:

- Root Cause -
java.sql.SQLException: open: java.lang.ClassNotFoundException: 
org.gjt.mm.mysql.Driver

I have even put mm.mysql-2.0.6.1.jar in tomcat/common/lib and it does not 
find the driver. I am asking this question on this list because it happens 
in struts-config.xml

so now I am looking into going over to the JNDI approach using  the guide 
at:

http://marc.theaimsgroup.com/?l=tomcat-userm=102225547106556w=2

but I am interested if there advantages to the JNDO pool ober the STRUTS 
pool if I go to all this trouble?

this seems like something alot people would care about.

Clay

Hi,

i am one of the guys trying to get a valid MysqlDataSource reference via
JNDI. But i am getting crazy without knowing where the problem is (perhaps
the reason is, i cant debug JNDI too good, cause i am no expert in it..)

i have the following:

  res-ref-namejdbc/TestDB/res-ref-name
  res-type javax.sql.DataSource/res-type
  res-authContainer/res-auth

i placed the mysql mm jar into commons/lib

When i run a servlet with the standard lookup code:
 try {
 javax.naming.Context jndictx = new InitialContext();
 if (jndictx == null) throw new Exception(Boom - No Context);

 DataSource ds =
 (DataSource) jndictx.lookup(java:comp/env/jdbc/TestDB);
 if (ds != null) {
[..]

i get no exception but i also dont get any reference returned from lookup.

I read tons of websites including the tomcat JNDI howto, without beeing 
able to understand it
better (in fact it gets worse cause of thousands of combinations in the web 
for server.xml and
web.xml)

When i leave out factory in the server.xml, i get a tyrex exception 
regarding loading a factory...

I just thought that using a datasource is better than just calling the 
DriverManager, but the
effort seems amazing... or i am too unclever... whatever...

thx for help.

Error on startup when using custom error pages

[Sefton, Adam]

Hi,

I'm trying to pick up error codes and display custom error pages. The one I'm working 
with currently is the 401 error in the case of failed logins. I've added the following 
in my /conf/web.xml:

error-page
error-code401/error-code
locationerror.html/location
/error-page

and I have error.html in the conf directory.

When I try to start the Tomcat server, I get the following errors:

ERROR reading java.io.FileInputStream@e06940
At Line 849 /web-app/error-page/ 

ERROR reading java.io.FileInputStream@90c06f
At Line 849 /web-app/error-page/ 

ERROR reading java.io.FileInputStream@766806
At Line 849 /web-app/error-page/ 

ERROR reading java.io.FileInputStream@c623af
At Line 849 /web-app/error-page/ 

Does anyone have any ideas? I recall reading somewhere that the custom error setup 
with TOmcat was quite buggy, is this the problem?

I am using Tomcat 4.0.3 standalone on Win2k

Cheers

Adam

Re: HTTP Status 500 - No Context configured to process this request

[mpauley]

Hi (Jose),

I  made  the  changes  you suggested but I'm still having problems.  Let me
give you a little more background:

The  website  we  would  like  to  drive  using  tomcat4  is located in the
/bioinformatics/webapps/bioinformatics directory (again, we're using RedHat
Linux 7.3; I don't think it matters but /bioinformatics is a RAID 0 drive).
Since  it  is possible that other websites might be developed in the future
that need tomcat we want to access it using
http://bioinformatics.ist.unomaha.edu/bioinformatics.   Thus,  lines  198 -
201 in my server.xml file now look like this

!--
Context path= docBase=ROOT debug=0/
--
Context  path=/var/tomcat4  docBase=/bioinformatics/webapps  debug
=0/

Note  that  bioinformatics.ist.  . . is a VirtualHost in Apache, configured
thusly,

VirtualHost 137.48.138.201
ServerName bioinformatics.ist.unomaha.edu
ServerAlias bioinformatics.unomaha.edu
DocumentRoot /bioinformatics/webapps
DirectoryIndex index.jsp index.html
/VirtualHost

Now  for  the  problem that we're having:  The website itself seems to work
butIcannot   access   any   of   the   manager   functions;   e.g.,
http://bioinformatics.ist.unomaha.edu:8180/bioinformatics/manager/list.   I
have  modified  the  tomcat-users.xml file to contain a user admin with a
role of manager.  This is the error message that I get:

Apache Tomcat/4.0.3 - HTTP Status 404 - /manager/list



type Status report

message /manager/list

description The requested resource (/manager/list) is not available.

Any  help  you  could  provide  to help solve this problem would be greatly
appreciated.

Other general questions (if you have time):
1)  I  know  that  tomcat  can not stand alone and requires Apache to work.
   However,  in  our  case,  how  do they interact?  Do we need to set up a
   VirtualHost?
2)  My  understanding  is that we need to specify the port when accessing a
   tomcat-enabled website, e.g., http://bioinformatics.ist.unomaha.edu:8180
   .   Is this true?  If so, is there any way to configure Apache/Tomcat so
   that the port number is NOT required?
3) Right now, all we have done is to use some include file statements in an
   otherwise  static webpage.  In this case, do we need a WEB-INF directory
   in .../bioinformatics?
4)  We  have not deployed anything but our application seems to work.  When
   is deploying necessary?

Hi Mark,

Your server.xml looks fine.

Question which URL are you trying to access?

If you are trying to access http://localhost/ you will get this
error because there is no context defined to answer this request, only
request of the form

http://localhost/examples/***

and

http://localhost/manager/***

will be answered since they are the only two context defined

If that is the case, do the following

Replace line 198 -200

!--
Context path= docBase=ROOT debug=0/
--

for

Context path=/bioinformatics docBase=bioinformatics debug=0/

which will create a context /bioinformatics, so you can access it using
http://localhost/bioinformatics/

Or you can setup this app as the default context as follows

Replace line 198 -200

!--
Context path= docBase=ROOT debug=0/
--

for

Context path=/ docBase=bioinformatics debug=0/

which will create a context /, so you can access it using
http://localhost/

well, I hope this helps you, let me know how it goes

  Context envCtx = (Context) initCtx.lookup(java:comp/env);
  DataSource ds = (DataSource) envCtx.lookup(jdbc/cdePool);

The driverClassName is indeed defined in the config.xml, and it appears
from catalina.log that it loads without a problem (meaning it's finding the
jdbc driver).

Here's the config.xml snippet:
Resource auth=Container name=jdbc/cdePool scope=Shareable type

ResourceParams name=jdbc/cdePool
  parameter

Has anyone seen this, or could offer advice?

Connection Pooling

[Kevin Passey]

Hi,

I am new to Tomcat so bear with me.

I have developed something using Websphere application server which has
connection pooling built-in.

Is there anything simple to plug in so that I can do the same with Tomcat?

Any docs or Howto's would be appreciated

Thanks

Kevin

If those log messages are bothering you, this is perfectly ok.
Look at the httpd.conf and find the directive LogLevel. It is by the
default set to warn.
Set the LogLevel error.

We are using the native logging for debugging and what are you seeing is
exactly that, the various stages of the connector itself.
The debug level itself is contolled with the debug=0..n for each worker
or channel, but in the code there is still some debugging code that
doesn't exactly follow that.

RE: APR not loaded?

Title: RE: APR not loaded?





I don't think this is related to your problem.


YOu can remove this message by copying jkjni (.dll or .so) (from the binaries for the tomcat connectors) into one of tomcat\bin or jdk\jre\bin (can't remember which). I think this dll/so is only necessary for in-process integration of tomcat and a web server.

I get this message in my catalina log file whenever I start Tomcat. I am

How often would Tomcat crash?

[Prashanth Pushpagiri]

Hello everyone:

I realize that this might not be a problem to find a
solution for on this forum, but any input on this
might help me debug my problem.

This morning I was told that my website running IIS
5.0/Tomcat 4.0.2 was not accessible. Since I was
physically unavailable in the office, I could pass
only do some remote debuggin with the help of my
colleague. Apparently, IIS was working and so was
Tomcat. But no one was able to access the website. It
gave a 404. Now, one of the things I should have done
was to check if tomcat was running on 8080 (although
the tomcat service was running in the services
console). A restart of Tomcat did not help either.
FInally I had to have the server restarted and
everything was back online again.

I finally made it to the office an hour later and
started checking the logs to find a reason for the
failure...I have not been able to do so! The logs
suggest nothing went wrong. IIS did not record any
logs for the period when the service was not
available. Can I attribute this to an IIS crash? I did
not find and indications in the event log if so. or
could it be a problem with the isapi redirector?

I know it is as difficult giving comments on such a
topic without substantial input from me as it was for
me this morning, but any suggestions on what may have
gone wrong would be very helpful.

Thanks
Prashanth

Re: How often would Tomcat crash?

[peter lin]

this is just a guess, but if there were no logs, was the log directory
full?

I know with NT4 and IIS that once the log directory reaches 200+ mb of
logs, it can cause IIS to stop responding. It probably isn't it, but
just in case I thought I'd mention it.

RE: Error on startup when using custom error pages

[Sefton, Adam]

Actually, I've managed to answer my own question - the location path needs to be 
from the web root of Tomcat. Now its working fine, but with an interesting problem.
Http Status 401 actually just means that authentication is required, which means that 
the site is automatically redirecting to the error page before asking for 
authentication ... is there any way of solving this? Or is it time I accepted I should 
be using FORM authentication rather than BASIC???

Cheers all

Subject: Error on startup when using custom error pages


Hi,

I'm trying to pick up error codes and display custom error pages. The one I'm working 
with currently is the 401 error in the case of failed logins. I've added the following 
in my /conf/web.xml:

error-page
error-code401/error-code
locationerror.html/location
/error-page

and I have error.html in the conf directory.

When I try to start the Tomcat server, I get the following errors:

ERROR reading java.io.FileInputStream@e06940
At Line 849 /web-app/error-page/ 

ERROR reading java.io.FileInputStream@90c06f

At Line 849 /web-app/error-page/ 

ERROR reading java.io.FileInputStream@c623af
At Line 849 /web-app/error-page/ 

Does anyone have any ideas? I recall reading somewhere that the custom error setup 
with TOmcat was quite buggy, is this the problem?

I am using Tomcat 4.0.3 standalone on Win2k

Cheers

Adam

Hello peter,

The log files are not close to 200 mb. These are
relatively new machines.

Also, my current log_level for tomcat is debug. What
other options are available? isapi.log seems to be
growing by the day!

Thanks

Oracle jdbc driver not found

[Carlton Lo]

I'm using Tomcat 4.0.4 tyring to access Oracle 8.1.7 via oci driver.

I've tried many different approaches, they are
1. save classes12.zip into TOMCAT HOME\common\lib and changed the extension to .jar
2. save classes12.zip into TOMCAT HOME\lib and changed the extension to .jar
3. save classes12.zip into TOMCAT HOME\server\lib and changed the extension to .jar
4. unzip all contents of classes12.zip into TOMCAT HOME\classes

non of these works, I was able to connection to the same database in Tomcat 4.0.2, but 
not 4.0.4

 So, these are debugging messages that can safely be ignored?
 

Yes, as all warnigs can, until something hit you in the head :)

There is even one debugging message that's get logged as [error].

Don't wory will be fixed.

Re[2]: Tomcat-4.1.6 and DBCP issue?

[Jacob Kjome]

Hello Remy,

Cool, that did it!  Just by replacing the 4.1.6 version of
commons-dbcp.jar with the 4.1.3 version made everything work again.

I guess this definitely means a regression was introduced into
commons-dbcp in 4.1.6.

 tomorrow to see if I did anything stupid, but the only difference seems 
 to be the tomcat version, so it would follow that something broke in 
 DBCP between 4.1.3 and 4.1.6.

RM It is easy to replace the DBCP included with another version or a new 
RM nightly if there is a problem (just replace commons-dbcp.jar in common/lib).

RM In the case of 4.1.6, some last minute changes were integrated in DBCP, 
RM so maybe there was some regression.

j_security_check question

[Kevin Andryc]

I am using a servlet as a login form that uses  j_security_check. When
submitted I would like it to return back to the same servlet with the person
now authenticated except that it gives me the error:

Type Status report
message Invalid direct reference to form login page
description The request sent by the client was syntactically incorrect
(Invalid direct reference to form login page).

Here is my web.xml file:

I have searched through the archives and it appears no one responded. Anyone
have a solution?

RE: APR not loaded?

[Short, Dave]

I put jkjni.dll (tomcat also wanted libapr.dll) in the tomcat\bin directory
and the message went away.  Now it complains about not being able to find
the ${serverRoot}/conf/workers2.properties file.  This file exists in the
Apache2\conf directory.  How can I point tomcat to the Apache2\conf
directory (basically, how can I sent ${serverRoot)?

I don't think this is related to your problem. 

YOu can remove this message by copying jkjni (.dll or .so) (from the
binaries for the tomcat connectors) into one of tomcat\bin or jdk\jre\bin
(can't remember which). I think this dll/so is only necessary  for
in-process integration of tomcat and a web server.

Hi all, 

Does anyone know what this message means: 

INFO: APR not loaded, disabling jni components: java.io.IOException: no 
jkjni in java.library.path 

I get this message in my catalina log file whenever I start Tomcat. I am 
trying to load a native library in a servlet with no luck so far and was 
wondering if this had anything to do with it. 

Thanks 

Jim.

RE: Updating files without restarting Tomcat

[Douglas, Rory]

Title: RE: Updating files without restarting Tomcat





You can specify the attribute 


 reloadable=true


in the context element for your web-application (in server.xml)


This will, however, watch all files for changes. There is no way to my knowledge of watching only some files.

Subject: Updating files without restarting Tomcat



I am using Tomcat 4.


I have a number of properties files in the WEB-INF/classes directory. I need
to be able to change the values of the properties in these files, but it
looks as though I need to restart Tomcat every time I change a value in
order for it to recognise the new version of the file. Is there any
configuration I can change so that it is not necessary to restart Tomcat
when I change the values of the properties. Is it possible for this to apply
just to specified files - I don't want it to check the status of all the
files in WEB-INF/classes because I know the class files won't change.


Thanks,
Catharine
