RE: Antwort: RE: Antwort: RE: user principal, realm

[Ralph Einfeldt]

As I understood your problem I think that you have to
implement your own RequestWrapper as your username is 
not in an official attribute but a private one. (So 
tomcat wouldn't know how to give this information to 
a realm)

More on extending a RequestWrapper:
http://java.sun.com/products/servlet/Filters.html#72674

Also note that Realms are tomcat specific.

If you are trying o deal with Realms and BasicAuthenticator
these will couple your application strongly with tomcat:

"Although the Servlet Specification describes a portable 
mechanism for applications to declare their security 
requirements (in the web.xml deployment descriptor), 
there is no portable API defining the interface between 
a servlet container and the associated user and role 
information. In many cases, however, it is desireable 
to "connect" a servlet container to some existing 
authentication database or mechanism that already exists 
in the production environment. Therefore, Tomcat 4 
defines a Java interface (org.apache.catalina.Realm) 
that can be implemented by "plug in" components to 
establish this connection. "

From: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.htm

RE: Using JMX with Tomcat - registering my MBean

[Michael Mattox]

I've narrowed this down to the fact that Tomcat isn't finding my
mbeans-descriptor.xml file.  I put this in my server.xml file:

  

But I have no idea where to place the actual mbean-descriptors.xml file.
Right now I have it with my Java classes under my WEB-INF/classes directory
but Tomcat must be looking for it some place else.

org.apache.catalina.connector.RequestWrapper

I'm wondering if I could just implement my custom authenticator (compare
BasicAuthenticator.java) or a custom Realm. But I don't know how I can
register my authenticator.
As mentioned already I want to read the delegated user from a http header
attribute and register it. Here the way how the BasicAuthenticator does it:
register(request, response, principal, Constants.BASIC_METHOD, username,
password);

My problem, am I free in choosing a constant? I don't have a password
because authentication has been done in the apache server which is in front
of tomcat.

I don't know if I have to write a custom authenticator, a custom Realm or
overwrite RequestWrapper. In all cases, how can I integrate my custom
classes in tomcat? I don't want to build a custom tomcat release.
Integration should be possible by configuration.

Re: JSP pages will not work for me. Please help

It looks like you've got a stray XML parser lying around somewhere.  My

Re: compilation of mod_jk, Solaris 8 (intel) using ANT

[Bill Barker]

I did this once a while back, just to see how.  Then I decided to stick with
"configure" and "make".

The main thing that is needed is to add ${java.home}/../include/solaris to
the  section of jk/native/build.xml.  If you a building from CVS
HEAD, that should be enough.  If you are building from the 4.1.x source
distro, then don't bother adding the check, since it doesn't evaluate the OS
anyway.

Also, you can avoid the sym-link with cc by defining:
build.native.cc=gcc
in jk/build.properties

Tomcat on Win2k with IIS problem

Hi all. I have connected Tomcat 4.1.18 on Win2k to IIS with
isapi_redirector2.dll. Everyting works except data uploading through
octed stream. When I try to save info to a file (GZip) archive comes
wrong. Snding data to Tomcat directly or usiage of the old
isapi_redirector.dll solves the problem. Had anybody got such kind of

Configuring Tomcat for multiple applications/users

[dwightHugget]

Can anyone point me to how to get this type of setup.
I want to have multiple instance of tomcat running on the same machine under 
different ports, say 80, 8080, & .
Would I achieve this if I setup an env variable called CATALINA_BASE as 
described in the RUNNING.txt file ?

I have only one server box and want to have a production, development, and 
experiment capability.

Finally, how can I run 2 different release of Tomcat ?
Say, I want to run 4.1.24 and 5 on the same machine.

thanks

Tomcat 4.1.24 Jasper Compile Problem

[Steve Vanspall]

Hi there,

I have this problem where Tomcat 4.1.24 doesn't let me compile the jsp's, I
assume, as you will se ein the error message, that tomcat has a problem with
there being spaces in the path to where it can find the JSP java code files.

in my case this is under the Program Files/Apache Group/Tomcat 4.1
directory.

the error I am getting is

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null

Generated servlet error:

4.1.19 had this problem also, 4.1.18 doesn't though.

I figured I would see if anyone is aware of this problem, and a way around
it. Prefereably, that solution would not be move webapp to a path that has
no spaces in it.

I was hoping that the problem would be fixed in this version, yes i did
report the bug to apache.

The reason I need 4.1.18+ is because there is a logging problem with 4.1.18
and SSL

Any help would be appreciated

SSL via files for Apache ?

[Jano Fetyko]

Hi all,
 
I have search the archive but didn't find an answer to my dilema. Our admin got me SSL 
certificate and private key that they use on their Apache server for SSL. It's signed 
by Verisign. 
 
I was wondering if there is a way to use these files to create the keystore instead of 
going through the process of creating the self signed cert. , submitting to Verisign

Re: Memory Woes

[Mark Pease]

Jake - you are a genius!  I reverted back to 1.4.0_03 and the memory leak
problem seems to have gone away.  I am heavily dependent on StringBuffers
for generating XML, so this bug was really causing problems.

Thanks for your time!

RE: session between domains

[Filip Hanik]

aahhh, now I see, you are asking about sessions between domains.
That is always gonna be impossible with tomcat as it is right now.
My question answered how to make a cookie persist across domains.

the answer on how to do the "sessions between domains" depends on how much
data you store in the session.

If you session has a tiny footprint, then store the data in the cookie
itself.
If you session has a medium footprint, then you could store session data in
the database,and then access it from all your servers since your "own"
cookie will have the ID.
If your session has a large footprint, then you performance is gonna be slow
no matter what, since I assume that your different tomcats are running on
different servers.

RE: Out of memory error

[Goehring, Chuck Mr., RCI - San Diego]

I just looked at this in Bug Parade.  They put out a J2SE Version 1.4.1_02 but the 
release notes don't mention this bug. The bug (4724129) is still listed as "In 
progress". I don't see a "Known problem" section of the release notes either.

This probably explains a bunch of problems reported recently on this list.

Re: session between domains

[Troy A. Griffitts]

Filip,
	Right, I think I understand your response, but, I believe I only have 1 
webapp on the server.

	Regardless, I thank you for your assessment of the problem, and for 
your helpful suggestion.  But I'm not quite sure what you mean:

"then keep track of it yourself"

Are you suggesting that I set the jsessionid in my own cookie?  If so, I 
couldn't find a function to get it, much less another function to use 
the jsessionid to retrieve the associated session object.

Otherwise, are you suggesting that I just extract the data that I need 
from the session and set cookies for it all, then grab the cookie data 
on the secure page?

Could i post to the secure page with the data maybe?

First things first, you need some standard way to determine the card
type.  

Then you need a configuration file which says do this for this card
type.  

This could be a series of rules to follow, or could be a list of objects
to
instantiate to process the card type.  

If it's going to go the object route you probably need to have a set of
interfaces that all different card handlers need to implement, and
possibly
a super class of some sort.

Anyway, enjoy working on it.

Here's some more info:

One database, several tables (about twenty).

The tables hold information about someone who uses the card, a
cardholder.

Each card has a particular type.

Each card type uses different information, for example one card type may
need the cardholder's name and address, while another may only need to
know
their number.

For the user (not to be confused with the cardholder) to use the system
they
need to be able to work with each kind of card and ONLY the data that is
relevant to that card.

The user also needs to be able to add new card types that use particular
data. This is why I think I need to store the information about which
fields
are relevant in a standard way. As new cards are added there needs to be
a
process in place for storing the information about that card.

I don't know what a rule processor or a rules engine is. 

My sense is that this is not a really complicated problem just one that
needs a fiendishly clever and simple solution. That's all ;).

1) Just to be sure, databases or tables?  Or since it's Oracle, do you
mean
different Schemas?  If it's different schemas then I'd create synonyms
into
a new schema for each of the different data sources (tables / schemas /
databases whatever).

2) Sounds like you need a rule processor.  If it were me I'd look at
what's
common between the different card types, and figure out how to determine
which card type you are working with.  Then based on the card type you
have
a rules engine, which may or may not load custom code for that card
type.  

Then again this sounds like you have a really elaborate need here, it's
not
going to be really easy to point you in a direction unless we have a
better
picture of what is going on.

I am stumped about how to manage a process.
 
Here is what I need to do:
I have several "cards". Each card accesses specific data from the
database.
Each card accesses a different collection of data from different
attributes
of different tables. 
For the user to work with the data (add, update, delete, search) the JSP
file must display the appropriate text boxes and drop down boxes for the
data relevant to that card. This will be different for each card. 

There will be new cards created that will have their own collection of
data.
The number of possible new cards is relatively infinite. That is why I
can't
do a specific JSP file 

RE: session between domains

[Filip Hanik]

tomcat sessions are not only specific to your domain, but also to the actual
webapp.

tomcat per spec can not share cookies across webapps, even less across
domain.

why dont you set your own cookie, and set the domain to myserver.com, and
then keep track of it yourself

I am stumped about how to manage a process.
 
Here is what I need to do:
I have several "cards". Each card accesses specific data from the database.
Each card accesses a different collection of data from different attributes
of different tables. 
For the user to work with the data (add, update, delete, search) the JSP
file must display the appropriate text boxes and drop down boxes for the
data relevant to that card. This will be different for each card. 

There will be new cards created that will have their own collection of data.
The number of possible new cards is relatively infinite. That is why I can't
do a specific JSP file for each card type: the card types that exist now may
disappear and new ones may appear.

How do I store the names of fields that are relevant to that card so that I
can access them when I need to display data about that

session between domains

[Troy A. Griffitts]

Hey guys.  I have a standard site, say:

http://mysite.myserver.com

And eventually the user gets to a place where we'll need to jump them to 
something like:

https://secure.myserver.com

to take their credit card information.  I lose my session when doing 
this.  Both URLs point to the same server and are served by the same 
webapp-- I can shop the whole site on https://secure.myserver.com/, but 
I can't make the jump.

I'm guessing it probably has something to do with my jsessionid being 
stored as a cookie.  I was wondering if I could force the 
';jsessionid=...' to the url or something.

Otherwise, how does one usually handle such a common thing with tomcat?

RE: Getting pretty far off topic here

[mike jackson]

It's that last little bit that's the hard part.  If you can I'd put a
column in the database that id's the card type (assuming you don't have
that already).

Also, remember that reflection is your friend...

Good luck.

First things first, you need some standard way to determine the card
type.  

Then you need a configuration file which says do this for this card
type.  

This could be a series of rules to follow, or could be a list of objects
to
instantiate to process the card type.  

If it's going to go the object route you probably need to have a set of
interfaces that all different card handlers need to implement, and
possibly
a super class of some sort.

Anyway, enjoy working on it.

Here's some more info:

One database, several tables (about twenty).

The tables hold information about someone who uses the card, a
cardholder.

Each card has a particular type.

Each card type uses different information, for example one card type may
need the cardholder's name and address, while another may only need to
know
their number.

For the user (not to be confused with the cardholder) to use the system
they
need to be able to work with each kind of card and ONLY the data that is
relevant to that card.

The user also needs to be able to add new card types that use particular
data. This is why I think I need to store the information about which
fields
are relevant in a standard way. As new cards are added there needs to be
a
process in place for storing the information about that card.

I don't know what a rule processor or a rules engine is. 

My sense is that this is not a really complicated problem just one that
needs a fiendishly clever and simple solution. That's all ;).

1) Just to be sure, databases or tables?  Or since it's Oracle, do you
mean
different Schemas?  If it's different schemas then I'd create synonyms
into
a new schema for each of the different data sources (tables / schemas /
databases whatever).

2) Sounds like you need a rule processor.  If it were me I'd look at
what's
common between the different card types, and figure out how to determine
which card type you are working with.  Then based on the card type you
have
a rules engine, which may or may not load custom code for that card
type.  

Then again this sounds like you have a really elaborate need here, it's

RE: Out of memory error

Oh, definitely, yes.  If you haven't used the -Xmx option then you are 
limiting yourself to 64meg of memory maximum!  You can hit that pretty quickly.

The multiple (100 per minute) mapping server lines occur before the out of

many of them.
I'll try the -Xms and -Xmx solutions and see if that helps. As I said it
doesn't happen often but it would be nice to track down the cause (or at

Once you hit an java.lang.OutOfMemoryError everything is in an inconsistent
state and I would not be surprised that you get lots of other error messages
thereafter.
The important question is are any of these messages appearing *before* the
initial out of memory error or *after* - if the're any before then I would
suggest investigating them otherwise I would guess that fixing your out of
memory error may fix your other error messages.

RE: Getting pretty far off topic here

[Sandra Patricia Hunter]

Here's some more info:

One database, several tables (about twenty).

The tables hold information about someone who uses the card, a cardholder.

Each card has a particular type.

Each card type uses different information, for example one card type may
need the cardholder's name and address, while another may only need to know
their number.

For the user (not to be confused with the cardholder) to use the system they
need to be able to work with each kind of card and ONLY the data that is
relevant to that card.

The user also needs to be able to add new card types that use particular
data. This is why I think I need to store the information about which fields
are relevant in a standard way. As new cards are added there needs to be a
process in place for storing the information about that card.

I don't know what a rule processor or a rules engine is. 

My sense is that this is not a really complicated problem just one that
needs a fiendishly clever and simple solution. That's all ;).

1) Just to be sure, databases or tables?  Or since it's Oracle, do you mean
different Schemas?  If it's different schemas then I'd create synonyms into
a new schema for each of the different data sources (tables / schemas /

Then again this sounds like you have a really elaborate need here, it's not

Subject: Getting pretty far off topic here

I am stumped about how to manage a process.
 
Here is what I need to do:
I have several "cards". Each card accesses specific data from the database.
Each card accesses a different collection of data from different attributes
of different tables. 
For the user to work with the data (add, update, delete, search) the JSP
file must display the appropriate text boxes and drop down boxes for the
data relevant to that card. This will be different for each card. 

There will be new cards created that will have their own collection of data.
The number of possible new cards is relatively infinite. That is why I can't
do a specific JSP file for each card type: the card types that exist now may
disappear and new ones may appear.

How do I store the names of fields that are relevant to that card so that I
can access them when I need to display data about that particular card? How
do I create new files of relevant fields when I create new cards?

I originally stored an SQL string that selects the relevant fields with the
table that holds other information about the card type. But what do I do
with it then? How do I take that SQL string and turn it into text boxes and
labels and drop down boxes?

Is there a better way of doing this that someone can think of?

1) Just to be sure, databases or tables?  Or since it's Oracle, do you

synonyms into a new schema for each of the different data sources
(tables / schemas / databases whatever).

2) Sounds like you need a rule processor.  If it were me I'd look at
what's common between the different card types, and figure out how to
determine which card type you are working with.  Then based on the card

that card type.  

Then again this sounds like you have a really elaborate need here, it's

RE: Out of memory error

[Januski, Ken]

Thanks Nikolaos,

The multiple (100 per minute) mapping server lines occur before the out of
memory error. But I now see that I also get these on days when there is no
memory problem. So I guess they're unrelated. It just seems odd to see so
many of them.

I'll try the -Xms and -Xmx solutions and see if that helps. As I said it
doesn't happen often but it would be nice to track down the cause (or at
least fix it so it doesn't recur).

Once you hit an java.lang.OutOfMemoryError everything is in an inconsistent
state and I would not be surprised that you get lots of other error messages
thereafter.

The important question is are any of these messages appearing *before* the
initial out of memory error or *after* - if the're any before then I would
suggest investigating them otherwise I would guess that fixing your out of
memory error may fix your other error messages.

RE: JDBC-ODBC bridge error

[mike jackson]

Remember though that Oracle and Access syntax is a little different.  If
most cases it doesn't matter, but sometimes it does.  For instance, if
you're working with dates it's a little different (if you're converting
the date from a SQL date to a text date).

However, that said, here's some things to consider:

1) PreparedStatements seem to be faster for data access when you're
talking to Oracle.  I don't know why this is, but when I switched from
Statements to PreparedStatements my speed went up.  Also with
PreparedStatements you don't have to worry about cleaning the input from
users prior to putting it into the SQL (example you're looking for
"'this'", the "'" is a reserved character).

2) If you're working with Oracle they have a XSQL Servlet in the XDK.
It's faster for accessing the database than anything I've been able to
write.  However that Servlet won't talk to Access.  This is also nice
because you can setup one xsql file to get the data and several xsl
files to format it for display.

3) If your web app is updating tables in Oracle you really ought to use
stored procedures in the database.  Access stored procedures and Oracle
stored procedures aren't the same syntax wise.  And they'll probably act
differently as well.

it is just a typo, I think what you want is this

String sqlString = "SELECT card_type.str_card_fields FROM card_type

cardType, is from you java and is a parameter

Wich connectors must i used if i want a secure connexion (ssl)

Once you hit an java.lang.OutOfMemoryError everything is in an inconsistent
state and I would not be surprised that you get lots of other error messages
thereafter.

The important question is are any of these messages appearing *before* the
initial out of memory error or *after* - if the're any before then I would
suggest investigating them otherwise I would guess that fixing your out of
memory error may fix your other error messages.

RE: How to hand in the passwords to 3000 users [urgent!]

[Goehring, Chuck Mr., RCI - San Diego]

Nancy,

Hope I understood you problem correctly.  It might be worth doing a signup 
application, then advertise it through the management chain of command with a url and 
instructions.  Have the app capture the information to a text file or database.  Get 
the email, username and password that way.  I think I'd also put password change & 
mailback capabilities in the app so you don't have to change passwords for users all 
the time.  

Chuck

Hi all!

I'm trying to entablish the best way to hand in their own user_id and

I don't know which could be the best way to do this without forgetting

Could you please help me?
Any clue could help me!
Thanks in advance!

RE: Out of memory error

[Januski, Ken]

No, I'm using 1.4.0, so that shouldn't be it.

But no one has answered my original question: Do the 100s of multiple
"mapping server nnn.nnn.nnn.nn" lines reflect another symptom or the
possible cause of the memory error? They just look odd to me and so I
wondered if they might be the cause of the problem.

I also have 2 instances of Tomcat running as services and need to add the
memory settings there in registry. I'll try that but I'm still curious about
my original question.

Thanks again,

Ken

JDBCRealm magic table names?

[G. Wade Johnson]

I just spent two hours tracking down a problem caused by new Oracle
tables we created for my application. I'm running Tomcat 4.1.18 with
Java 1.4.1.

Our DBA created tables for my system to use with authentication thru
the JDBCRealm. I populated the table and attempted to log in. The
system consistently refused my login.

After digging in the source of JDBCRealm, I found that no matter what
I did, the request for the password would return null if the name of
the table is 'WEB_USER'. If I change the name of the table, everything
works.

Does this make sense to anyone?

I can have the table name changed, but I'd like to know why that
name is special.

RE: Out of memory error

[Nikolaos Giannopoulos]

(1) We are seeing what seems to be this bug as well (we have no JSPs in our
app btw) - Could it be that by using IBM's JRE for 1.4 that Steve
essentially worked around this bug

(2) I think its silly that SUN has slated fixing this bug for 1.5 and their
workaround makes very little sense - Anyone know what the following stated
work around translates to in actual code?

"Don't reuse StringBuffers. If you do reuse them, check their capacity and
make sure that you aren't making tiny Strings from huge StringBuffers"

(3) Steve, last time I downloaded an IBM JRE (a real long time ago) it was a
real pain as it was (a) buried within many nested web pages and (b) was part
of a websphere download - Do you offhand have a direct link to (just) IBM's
1.4 JRE?

Thanks,

jasper2/jspc null pointer errors on jsps with taglib/jstl

[Hammad Sophie]

Hi.

My project has jsps, some of which use jstl/jakarta taglibs.
I use ant to pre-compile/compile my jsps manually. All jsps which dont use
taglibs still precompile/compile happily. However jsps with jstl/taglibs do
NOT compile with ant because of some nullpointer exception:

jsp_precompile:
 [jspc] Compiling 64 source
filesC:\jakarta\tomcat\work\Standalone\localhost\northstar
  [jasperc] 2003-03-31 04:08:57 - ERROR-the file
'\Accounting\GL\Budgets\budgetSetupWizard\budgetList.jsp' generated the
following general exception: java.lang.NullPointerException
  [jasperc] error:org.apache.jasper.JasperException: Error compiling
\Accounting\GL\Budgets\budgetSetupWizard\budgetList.jsp
  [jasperc] at org.apache.jasper.JspC.processFile(JspC.java:596)
  [jasperc] at org.apache.jasper.JspC.execute(JspC.java:800)
  [jasperc] at org.apache.jasper.JspC.main(JspC.java:822)
  [jasperc] Java Result: 9

The interesting thing is that these same jsps run with no problem on tomcat,
i.e. tomcat will precompile/compile them at run time and they work fine

Does anyone know whats going on? How can I get Ant to do the precompile.

I posted this on the ant-user list thinking it was an Ant problem. However,
it seems like it is more of a jasper/tomcat issue My message on the
ant-user list and its reply:
http://marc.theaimsgroup.com/?t=10491575861&r=1&w=2

My environment:
ant 1.5.2
tomcat 4.1.21
taglibs 1.0
jdk 1.4.1_01

Thanks.

Howdy,
Make sure you're using:

- The JDK (not JRE)
- The right version of the JDK (preferably the latest stable version)
- An OS that has the patches required for the JDK, if any

This was a known bug in JDK 1.4.0b92 or something like that: search the

Hi Sandra,

> String sqlString = "SELECT card_type.str_card_fields FROM card_type
> WHERE (((card_type.str_card_type=cardType));";

you are using 3 opening brackets and only 2 closing ones in your where
condition. IMHO it would be correct SQL to write:
"SELECT card_type.str_card_fields FROM card_type WHERE
card_type.str_card_type=cardType;" instead, no need for brackets there.

Regards Jan

RE: JDBC-ODBC bridge error

[PELOQUIN,JEFFREY (HP-Boise,ex1)]

I get errors like that with coldfusion pages connecting to access if the
variable type does not match the database field or if the value is null.

if the database field is a string you I need to use single quotes around the
value in the sql statement

   String sqlString = "SELECT card_type.str_card_fields FROM card_type
WHERE (((card_type.str_card_type='cardType'));";

Also, how are you getting the value of cardtype into the select string if
everything is within the double quotes?

what about

   String sqlString = "SELECT card_type.str_card_fields FROM card_type
WHERE (((card_type.str_card_type='"+cardType+"'));";

Re: -Djava.endorsed.dirs=

[Ramiro Gonzalez]

The JAVA_HOME don't have to include then /bin directory...

so the correct could be:

JAVA_HOME
C:\Programme\Java\j2re1.4.1_02
BUT...

you need the SDK, not just the runtime, (j2re is the runtime).

So, go to java.sun.com, and download the latest SDK.

Saludos!

compilation of mod_jk, Solaris 8 (intel) using ANT

[Filip Hanik]

hey ya'all

I am compiling mod_jk on Solaris 8 on intel platform using ANT. I am
compiling everything fine except jk_jni_worker.c that completely barfs on
me.

I had to do some tweaks before I could get the rest to work here are the
steps

1. Add libtool to my path
2. Create a symbolic link from /usr/local/bin/gcc to cc and add that to my
path so when the program invokes cc it actually runs gcc.

forget about mod_jk2, that one has so many errors it hurts my eyes :)
but for mod_jk the only file that doesn't compile is jk_jni_worker.c, now I
am compiling with jdk 1.4.1, and the errors I am getting is some missing or
invalid header files from JAVA_HOME/include

anyone succesfully compiled with another jdk, or with jdk1.4

Silent Installation of Tomcat 4.0.6

[Timon, Vince]

I have been searching multiple forums high
and low for a definitive answer to the following question:

 

Is there a way to silent install tomcat
4.0.6, meaning the installation runs without displaying the user interface and
the program uses default values or a response (.iss) file to complete the
install? 

 

If there is a way to do it, could someone
provide the actual mechanism? Thanks in advance for any help. 

 

tomcat/apache manage ssl

[noel . jean-baptiste]

Hello, 
With tomcat 4.0.6 
My tomcat is connected with Apache and I would like to have a 
connection protected with tomcat, but not for all my webApp of 
tomcat.  
The Apache server does not have protected connection SSL, and i don't 
want than Apache manage them.  
1. Is this possible to have Apache connected with tomcat but it is 
tomcat which manage the SSL?  
if ok, 
1.1 can i have 2 virtual hosts in the same "Engine" of tomcat, one to 
have a protected connection SSL, the other a normal connection?  
1.2 If not, must i have two different "Service" of tomcat?

RE: tomcat IIS configuration please help

Do you get a 200 for the isapi rediretor in the iis logs? If you get a 401,
like I did for a few days, then it can't find the page it's supposed to be
redirecting to and something's still amiss on iis side.

I asked the same questions about 2 weeks ago and got some useful responses.
Let us know what the logs say and maybe someone can tell you what to try
next.

RE: Not starting with j2ee.jar in /lib direcotry

[Shapira, Yoav]

Howdy,
Get the classes you need piecemeal, e.g. mail.jar and activation.jar for
JavaMail.  Don't use j2ee.jar as it creates conflicts, for example with
the javax.servlet packages.

If you need all of J2EE, get a J2EE container e.g. JBoss, as tomcat
doesn't fill your needs by itself.

Chris,
I second that.  It's a great book.  You'll need an EJB container
as well and I suggest OpenEJB.  It can be found here:
http://openejb.sourceforge.net

	It integrates tightly into Tomcat and is very simple to
install/configure/use.  I'd love to help you out with it if you go 
that
direction.  Later, Jeremy

RE: Tomcat not excepting changes in web-app

[Shapira, Yoav]

Howdy,
Tomcat doesn't cache any of this in a way that persists across restarts.
If you deploy a changed version of a class to the server and restart it,
the new class will be loaded, as it's a new JVM instance, new
classloader, etc.

Any other behavior you're seeing is most likely an error of your part,
and could be one of many, e.g.

- Your code doesn't refer to this class
- You haven't really redeployed the class
- You have multiple versions of the class in the classpath, e.g. in
WEB-INF/lib and common/lib.
- You haven't really restarted the server
etc.

It is often useful to add logging, even in a static initializer block if
you have to, so that you know how your class is being used, when it is
loaded, etc.

Antwort: Tomcat not excepting changes in web-app

[horst . scheruga]

You did not write how you deploy the changed class.

Webapps are stored under the webapps directory
There exists the war file and for each war file a directory with the
unpacked content of the war file.
Replacing all of this and restarting Tomcat should do it.

Hi List,

I keep on having the following trouble...

I have a web-app that connects to a database, the connection parameters are
stored in a static class that serves only this particular cause. Whenever I
need to deploy to a new context (e.g. DB Server) I get the following error:

java.sql.SQLException: Cannot connect to MySQL server on
OLD_DB_SERVER:3306.
Is there a MySQL server running on the machine/port you are trying to
connect
to? (java.net.ConnectException)

Where OLD_DB_SERVER would be the name of the formerly used parameters. It
seems that Tomcat stores those seetings somewhere, even if I remove the
whole
class, that Exception is thrown.

My setup:
Server VersionApache Tomcat/4.1.12
JVM Version   1.4.0-b92
JVM VendorSun Microsystems Inc.
OS Name   Windows 2000
OS Version5.0
OS Arch   x86

I have tried to start/restart the server, delete whats in
/work/,
reloading through the web-app Manager, constant recompiling of class in
question as well as combinations of these. So far nothing seemed to solve
the
problem. Eventually (after ages) he has, so far at least, excepted the
changes - but I am going nuts trying all those steps without any clue as to
how this should really work.

Am I not seeing the obvious, or has anyone made similar experiences?

Does mod_jk2 and JNI work with the Apache2 prefork MPM?

[Ken Cox]

I'm stuck trying to use mod_jk2 (2.0.2) to connect Tomcat (4.1.24) to my
prefork Apache (2.0.45) via JNI.  Does anyone know have this type of setup
working?

What I really want is a servlet engine running in Apache's processes,
so that it can make JNI calls back into my (thread unsafe) C++ code.

Thanks,
Ken

Set the memory using -Xmx and -Xms.  This should take care of the memory

If you want to monitor the heap usage, add -verbose:gc

what's wrong with Example.ldif

[Karamat Adil IHMD]

Hi all,
   Can any one tell me why I cant run the sample file that is on the Tomncat
website for adding entries in the OpenLdap directory tree ? The file is as
follows

 --
 # Define a user named 'tomcat'
 dn: cn=tomcat,dc=xxx,dc=com
 cn: tomcat
 userPassword: tomcat
 sn: Tomcat User
 objectClass: person
 
 # Define a user named 'both'
 dn: cn=both,dc=xxx,dc=com
 cn: both
 userPassword: tomcat
 sn: Both User
 objectClass: person
 
 # Define an entry to base role searches on
 dn: dc=roles,dc=xxx,dc=com
 cn: roles
 objectClass: person
 sn: Roles Entry
 
 # Define all members of the 'tomcat' role
 dn: cn=tomcat,dc=roles,dc=xxx,dc=com
 cn: tomcat
 objectClass: groupOfUniqueNames
 uniqueMember: cn=tomcat,dc=xxx,dc=com
 uniqueMember: cn=both,dc=xxx,dc=com
 --
 
 OK it adds the first two entries i.e tomcat and both and then when it tries
 to add the third entry it gives the following message :
 
 adding new entry "dc=roles,dc=xxx,dc=com"
 ldapadd: update failed: dc=roles,dc=xxx,dc=com
 ldap_add: No such attribute (16)
 additional info: naming attribute 'dc' is not present in entry
 
 
 What am I doing wrong 
 Thanks,
 Adil

JK2, listening on different port/address using server.xml

[Kundrot, Steven]

Strange behavior with JK2, Tomcat 4.1.12 on Linux 7.2.

I configured JK2 with the default settings.  Everything worked fine.  I
attempted to change the server.xml to use a different port than 8009.  So, I
updated the server.xml to use port 8089.  The change took.  The admin webapp
displays the changes.  I stopped and restarted tomcat.  Interestingly, the
JK2 connector still listed on port 8009.  In order to make it work, I had to
modify jk2.properties and add the line "channelSocket.port=8089".  The
jk2.properties.save file, which is generated at startup had an entry of
"port=8089".  So the jk2 connector was reading the server.xml correctly, but
it was not using the jk2.properties.save file.  In addition, the
jk2.properties.save file didn't have the line right.  If you put "port=8089"
in the jk2.properties, it doesn't work.  You need to have
"channelSocket.port=8089".  I'm having similar problems with the address
attribute.  I'd like to specify the IP address that the JK2 listener should
bind to, but the address attribute in the server.xml and in the
jk2.properties file seems to be ignored.

Thanks, this page was a great help.  I'm stuck on one thing, what is the
"Group" in the mbeans-descriptors.xml file?  I have everything else set but
I'm still getting:

javax.management.ReflectionException: The MBean class could not be loaded by
the default loader repository

So I'm not sure if it's the group or something else I missed.

Well here is the issue.  I am running a site, I need to upgrade a
few things and all my users just got kicked off in the process.
This seems to me like a major problem.  Am I supposed to wait until
3 in the morning to implement updates to the code?  This just seems
unreasonable.  While keeping all session data you loose the one part
of it that holds it all together?

I believe that during restart of a context, all sessions get serialized to
disk.
but the serialization does not serialize the principal. You can try to file

I have a gut feeling you want to know how to keep a parameter across requests. 
There is an abstraction called "session" for storing data across multiple 
servlet requests from the same client. Check the 
javax.servlet.http.HttpSession interface and, in particular, its setAttribute 
and getAttribute methods.

You can use on of the existing realms.  Create a file or database table
as outlined in the realm how-to document, containing the users and roles
you want.  Define the appropriate realm in server.xml.  Define the
security constraint elements in your web.xml.

Request.getUserPrincipal() is the servlet specification standard way to
do this.  And Request.isUserInRole() is the standard way to check if the
user is a member of a certain group.

It's good that you don't want to re-invent the wheel.  I don't think you
have to do much coding given your requirements.

JDBCrealm drops user after manager reload

[Dan Allen]

I am having a fairly painful problem here dealing with
authentication using the JDBCReam and container managed security.
In particular I am using securityfilter, but I seriously doubt that
this problem involves that application directly.

If I use the default SecurityRealm that comes with the security
filter application, which just manual sets the userInRole and
getRemoteUser information, I can reload the context over and over
and never drop the user.  When I use JDBCReam to handle users in a
database and I reload the context after logging in all the active
sessions loose their security principals and roles.  The thing is,
all the session data is still there, working as normal.  I get no
messages in the log files regarding a failure of any kind.

In short:

Why does a context reload kill the user principal information and
how can I fix it?

To duplication:

Grab securityfilter from securityfilter.sourceforge.net  Log in out
of the box, reload the context and view the securePage.jsp again.
No problem.  Now, change the realm to JDBCRealm, login, reload
the context and visit the securePage.jsp...aha, now it says you are
not logged in and takes you to the login page.

Re: shared resources - a final answer?

[Pat McGroin]

Can anyone tell me which is right?
Do shared resources across applications go in $CATALINA_HOME/common or 
$CATALINA_HOME/shared?

The HOWTO doc. says the shared dir. is the place to put these resources.
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html

However, Paul tells me that I need to put jar files under $CATALINA_HOME/common 
directory since they can be seen by both engine and application and that 
$CATALINA_HOME/shared directory are only available to Catalina engine, not my 
applications.
I do not have the WROX book he refers to.

My test worked with a shared JAR file in the common dir. but failed with the JAR file 
in the shared dir. so it appears the doc. is wrong.
Is this a known bug or am I reading the documentation wrong?

Thanks.

Apache Virtual Host host1 (http://host1.com) -> Tomcat 1
Apache Virtual Host host2 (http://host2.com) -> ALSO Tomcat 1

I've tried many variations of workers.properties, even setting up load-

Suggestions needed - customizing authorization

[Barley]

Before I dive into hacking a bunch of Tomcat source
code, I would very much like to solicit the opinions of
some more experienced users.

I need a form-login authorization scenario that
integrates with some of my other webapps. Specifically,
I need to know the username, real name and group info
of the person who has logged in.

I used to use Resin, and my solution was something like
this: I created my own custom Authenticator class
(similar to Tomcat Realms). Resin passed the
HttpServletRequest to the Authenticator class. I
queried a MySql database to verify login information,
and then inserted some values from the database into
the HttpSession of the request that was passed. That
way, later on, my apps could look in the session to
find out about arbitrary pieces of information I had
stored about who had logged in.

My initial thought was to create a custom Realm, but I
don't see a way to access the HttpServletRequest that
is seeking authentication. Have I missed something
there?

Does anyone have any other suggestions for
accomplishing what I am trying to do? Is there a way to
access the Principal of a given request after the user
has been authenticated? Would it maybe be possible to
create a custom Principal capable of storing the other
properties I need? Any pointers, suggestions or ideas
would be much appreciated. Also, if you know of any
projects that have already done this, I'd love to check
them out so I'm not reinventing the wheel.

I'm having some fun with some applications supplied to us that may be
casuing a problem wiht each other, i.e. one application may be causing 
the
whole tocat environment to fail - thus affecting the others.

I'm toying with the idea of trying to run a signle apache but with
multiple tomcats - one per application. Does anyone have any views on 
this
?

Cheers - Steve

RE: inconsistencies in Tomcat handling servlet filters...

[Jacob Kjome]

Many thanks to Jonathan Leech for pointing out how to fix my problem 
(below).  See the original thread here:
http://marc.theaimsgroup.com/?l=tomcat-user&m=104759543729238&w=2
and then the code I forgot to attach to the original message here:
http://marc.theaimsgroup.com/?l=tomcat-user&m=104759559429435&w=2

He asked me to forward it to the list since he isn't a subscribed 
member.  So, here it is (below).  Now the only issue left is why the third 
example I mentioned still doesn't work ...

Given this code

out.write("PRE");
CharResponseWrapper wrapper = new 
CharResponseWrapper((HttpServletResponse) response);
chain.doFilter(request, wrapper);
out.write(wrapper.toString());
out.write("POST");

It prints out everything for jsp pages but only the following for html page...

PRE

Lesson 3


This is a pure test page





The missing data is this...


POST
I guess this is the one last mystery to solve.   It must have something to 
do with not setting the content length, but why would it affect the 
filtering of html pages and not jsp pages?  H  Anyone have a guess 
as to why this is happening?

Jake,

I think I can help you out  Do me a favor though and post/forward this
response to the tomcat mailing list because
I'm too lazy to figure out how to subscribe and reply properly.
The simple answer is you need to flush() your PrintWriter.  Do this:
GenericResponseWrapper.java:
PrintWriter writer = null;

public byte[] toByteArray() {
   if (writer != null) writer.flush();
   return output.toByteArray();
}
public String toString() {
   if (writer != null) writer.flush();
   return output.toString();
}
public PrintWriter getWriter() {
   writer = new PrintWriter(getOutputStream(), true);
   return writer;
}
> Questions to answer...
>
> 1.  Why don't all 3 examples produce exactly the same output?  It
> seems to me that they should.
The first example will work fine with the modifications I suggest above.
I don't know what's wrong in the third example, but perhaps it will work as
well.
> 2.  Why does using a response wrapper that uses a ByteArrayOutputStream

flush()ing the PrintWriter cures this.  Incidentally, if your .jsp writes
enough data you will get some data but the rest truncated.
> 3.  Why do I have to use a PrintWriter when filtering JSP's?  Why

The spec says in the Servlet you've got to use one or the other, but not
both.  You
should be able to relax this constraint in your filter if everything is
kosher.  Perhaps
flushing the PrintWriter properly will fix this as well.

Looks to me like your code would have worked just fine, as mine did, in
older versions
of Tomcat, but that they stopped flushing the PrintWriter for you after the
.jsp runs, at
some point between 4.0.3 and 4.1.18

sample openLdap ldif file wont work

[Karamat Adil IHMD]

Hi all,
   Can any one tell me why I cant run the sample file that is on the Tomncat
website for adding entries in the OpenLdap directory tree ? The file is as
follows

 --
 # Define a user named 'tomcat'
 dn: cn=tomcat,dc=xxx,dc=com
 cn: tomcat
 userPassword: tomcat
 sn: Tomcat User
 objectClass: person
 
 # Define a user named 'both'
 dn: cn=both,dc=xxx,dc=com
 cn: both
 userPassword: tomcat
 sn: Both User
 objectClass: person
 
 # Define an entry to base role searches on
 dn: dc=roles,dc=xxx,dc=com
 cn: roles
 objectClass: person
 sn: Roles Entry
 
 # Define all members of the 'tomcat' role
 dn: cn=tomcat,dc=roles,dc=xxx,dc=com
 cn: tomcat
 objectClass: groupOfUniqueNames
 uniqueMember: cn=tomcat,dc=xxx,dc=com
 uniqueMember: cn=both,dc=xxx,dc=com
 --
 
 OK it adds the first two entries i.e tomcat and both and then when it tries
 to add the third entry it gives the following message :
 
 adding new entry "dc=roles,dc=xxx,dc=com"
 ldapadd: update failed: dc=roles,dc=xxx,dc=com
 ldap_add: No such attribute (16)
 additional info: naming attribute 'dc' is not present in entry
 
 
 What am I doing wrong 
 Thanks,
 Adil

RE: Seperate tomcats - one apache

[George Sexton]

I routinely run via the CATALINA_BASE method for multiple instances and have
no problems.

Using mod_jk, all you have to do is define the connectors to be on different
ports, and then configure each servlet engine to run mod_jk on a different
port.

Slightly OT: SocketException with MySQL

[Geoff Peters]

I am using Tomcat 4.1.18, MySQL 3.23, newest driver, running on Linux 7.3. Problem is 
similar to others who have posted on this subject, just want some advice (can't seem 
to get a definite answer). 

I'm not using connection pooling. If I walk away and leave the server running for 
several hours, I come back and cannot access the database via the servlet, the 
catalina.out file tells me "SQL Error: Communication link failure: 
java.net.SocketException". Happens whether or not I am running TOmcat remotely on or 
the same box as MySQL (i.e. not a network issue). I made sure all of my connection 
objects were close in the destroy() method of each servlet thinking all of the sockets 
were full, still didn't work. I just recently set autoReconnect = true in my 
server.xml realm tag - that doesn't seem to make a difference.  

Should that work? Or, should I be closing the connection object IMMEDIATELY after each 
executeUpdate or executeQuery? Currently am opening a connection in the init() method, 
and killing in the destroy(). 

Any suggestions greatly appreciated!! 

Thanks, Geoff

the latest stable release?

[Xu, William [CC]]

http://jakarta.apache.org/tomcat/index.html This page (paragraph 2 in
section Tomcat 4.x) still shows the latest stable release is 4.1.18 as
opposed to 4.1.24. Is there any specific reason for that or just that page
has not been updated? Thanks in advance.

RE: DriverclassName is required (mysql)

[Mark.Gargan]

Hi Folks,
I was using the Tomcat within the Java WebServices Development
Pack from Sun. I promptly got rid of it cos I like my dos output. 

Now instead of getting the error that the driverClassName is required,
now Tomcat says that it cannot load JDBC class null. This would be fair
enough only I've set the driverClassName property in the server.xml that
describes the datasource to be the org.gjt.mm.mysql.Driver class. It
looks like the name of the parameter that tells the the connection
factory which datasource to use is different to 'driverClassName'. Could
this have changed?

Thanks,
Mark.

Subject: DriverclassName is required (mysql)

Hi Folks,
I'm trying to install jUDDI in my tomcat installation.
The installation is from the java webservices pack from the sun site. 
I'm trying to setup mysql as the underlying database for the UDDI
Registry.
 
I've inserted the following context into the server.xml as instructed in
the JNDI howto Datasources guide.
 


   
 
   
 
   
  
 factory
 
 
org.apache.commons.dbcp.BasicDataSourceFactory
  
 

  
 maxActive
 
 100
  
 

  
 maxIdle
 
 30
  
 

 
  
 maxWait
 
 1
  
 


  
 username
 
 javauser
  
 
  
 password
 
 javadude
  
 


  
 driverClassName
 
 org.gjt.mm.mysql.Driver
  
 

  
 url
 
 
jdbc:mysql://localhost:3306/javatest?autoReconnect=true
  
   
 
 
Unfortunately when I go to call the test.jsp which in turn makes a call
to the init method in the foo class :-
 
public void init() {
try{
  Context ctx = new InitialContext();
  if(ctx == null ) 
  throw new Exception("Boom - No Context");
 
  DataSource ds = 
(DataSource)ctx.lookup(
   "java:comp/env/jdbc/TestDB");
 
  if (ds != null) {
Connection conn = ds.getConnection();
  
if(conn != null)  {
foo = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
ResultSet rst = 
stmt.executeQuery(
  "select id, foo, bar from testdata");
if(rst.next()) {
   foo=rst.getString(2);
   bar=rst.getInt(3);
}
conn.close();
}
  }
}catch(Exception e) {
  e.printStackTrace();
}
}
 
it begins to resolve the DataSource and then throws the following
exception..
 
javax.naming.NamingException: DbcpDataSourceFactory:  driverClassName is
required
  at
org.apache.naming.factory.DbcpDataSourceFactory.getObjectInstance(DbcpDa
taSourceFactory.java:199)

org.apache.naming.SelectorContext.lookup(SelectorContext.java:183)
  at javax.naming.InitialContext.lookup(InitialContext.java:347)
  at foo.DBTest.init(DBTest.java:26)
 
 
I can't really tell what the problem is as the driverClassName seems to
be defined in the xml.
The mysql-connector-java-2.0.14-bin.jar is placed in
${CATALINA.HOME}/common/lib so the classes are available? 
 
Anyone got any ideas? This is me falling at the first hurdle here.
Doesn't bode well for me at all. 
 
Thanks,
Mark.
