mod_jk under darwin (OS X)

[Morten Rønseth]

Hi all,

I'm trying to get mod_jk to compile under OS X but it seems that it relies
on glibc - which is not (yet?) ported to Darwin.

Does anybody know if this happens to be the case and if so is there any
other way to get mod_jk to compile?

Cheers,


-Morten

RE: Tomcat/LoadBalancing.

[GASNIER Lise]

you have to add your worker loadbalancer in the worker list...:
worker.list = loadbalancer and mount your servlets and jsps to loadbalancer

 Objet:Tomcat/LoadBalancing.
 
 Hello,
 I want to enable the load balancer worker on Apache/Tomcat. Even though
 I have configured the workers.properties file as -
 worker.loadbalancer.type=lb
 worker.loadbalancer.balanced_workers=myajp12_1, myajp13_1, myajp12_2,
 myajp13_2
 
 The load balancer worker is not invoked, for I do see the debug
 statements for lb worker in mod_jk.log.
 
 Could you tell me, what is it that I am doing. What additional
 configuration do I need to do to enable load balancer.
 
 Any help in this regard is appreaciated.
 -Vikas.

3.3-M2 conf/users files

[Peter B. West]

In 3.3-M2, the users files for SimpleRealm have been split into
admin-users.xml
example-users.xml
global-users.xml
tomcat-users.xml

My server.xml, which may be a hangover from a previous version of
tomcat, has the following line for SimpleRealm:
SimpleRealm  filename="conf/users/global-users.xml" /

What is the intended use of these multiple files?  How are they to be
specified?

Re: can SSL an non-SSL run at the same time??

[Pae Choi]

Gomez,

I know you were involved in mod_jk at least for apache 2.0 from 1.3.x.
Have you built the mod_jk with apache v1.3.17 and v1.3.19 with "EAPI"
option. It seems like the option, EAPI", is completely removed from both
versions. Then do we have any info regarding on the reasons and effects
on this change, "EAPI" from 1.3.14 to later versions. Thanks


Pae



 I running Tomcat as a standalone using SSL.
 What i'm hoping to do is that one context with non-SSL and the other
 context is with SSL.

Well, that helps clarify the question.  Unfortunately, I don't have an
answer for you (i.e. I don't know) -- but perhaps someone else does.
This is certainly a very reasonable/desirable capability to have, so
if it's not available, it would be nice if it were added.  FWIW, I'm
pretty sure you can do what you want with Apache with mod_ssl (which
is what I'm using -- but I haven't tried doing that yet).

I strongly recommand you to use mod_jk to handle this situation.

1) native http connector are still not as secure as apache could be

2) handling SSL / NON-SSL via mod_jk (and mod_ssl) in Apache is very
   easy, and works fine (used in my prods servers for months)

Re: security question

[skolski]

Hello Jeff, Hello List,

thank you very much for your reply. A look at this example would have
prevent me from spending a lot of time and writeing the other mail. The
build in example doesn't work at my installation. That j_security_check
stuff is missing. But that doesn't matter, I try to use basic auth for the
first throw.

I copied the parts of examples web.xml to my context and modified the path.
If I try to surf to that "secret" path the password box pops up. The
password box then only accepts the valid users, so far everything is o.k.
But then there is a 404 Error. The Browser points to the right file in the
right directory but there is a 404 not found. How is that possible? What do
I do wrong?

thannks in advance,

Sascha

We also suffer from this behavior -- without any real idea how to get

However it seems to me that the known problem with IE+keepalive can be
seen at some(?) versions of IE5.0, thus I'm trying:
BrowserMatch "MSIE 5\.0" nokeepalive downgrade-1.0 force-response-1.0

Definitly the failure on 301/302 redirector requests vanished, I also 
does not get a negative feedback on the "This page cannot be accessed..."

by Kresmir is non-deterministic this may also be a false guess ...

too many java processes ???

[kreso]

When we run tomcat, it opens about 30 java 
processes and it takes
a lot (almost all) of our 128 MB memory. Is that 
supposed to be?
We are running it on linux.
Processes look something like this...

Servlet newsgroup discussion on news.groups

[Jon Skeet]

Title: Servlet newsgroup discussion on news.groups






Greetings!


This message is being posted here (and to other places where servlets

are discussed) because there is a Request For Discussion (RFD) on

the news.groups Usenet newsgroup concerning the proposal of two new

Java newsgroups:


comp.lang.java.servlet

comp.lang.java.server-side


If you are not interested in Usenet or feel you wouldn't use the new

groups, please ignore this message and accept my apologies for wasting

your time.


If you wish to view the proposal and comment on it, however, I would

be very happy to hear your views. The subject line of the RFD is:

2nd RFD: comp.lang.java.server-side and comp.lang.java.servlet and

the article ID is: [EMAIL PROTECTED]


Discussion of the RFD should be carried out on news.groups, but if

you don't wish to post there yourself I'd be happy to post on your

behalf if you wish to mail me at [EMAIL PROTECTED] If your

news-server doesn't carry news.groups, a copy of the RFD has also

been posted on comp.lang.java.programmer, comp.lang.java.databases,

and comp.lang.java.corba - or I'd be happy to mail you a copy. If

you wish to read news.groups on the web, http://groups.google.com

provides an updating archive of posts, although it's usually a

couple of days behind.


NOTE: Due to the large number of mailing lists and discussion boards

this message has been posted to, I won't be able to participate in

any discussion on the list/board itself. Furthermore, it would be

counter-productive to have several small discussions, one in each

area. Please use news.groups instead. I apologise if you feel this

request is poor netiquette - I'm usually a great fan of read where

you write myself, but I hope you'll see this as a slightly unusual

case.


The feelings of the Java community are very important on this matter

- and when it comes to the vote, the new groups will only pass if

there is sufficient support. I'll post another message here when

the Call For Votes (CFV) takes place, so you don't need to read

news.groups in the meantime if you don't want to.


Thanks for reading,

Jon Skeet - [EMAIL PROTECTED]

Re: too many java processes ???

[John Clark L. Naldoza]

Hi,


Are you using Multi-threaded Applications???  If so, this would be
natural...;-)  

With the Linux Operating System...  Threads are actually reported as
being processes...;-)

Try using top or ps -aux and add up the memory usage of the
processes...;-)

However, this does appear to be quite odd, if you have just run tomcat
and checked out the number of process running right away...;-(

What version of the Linux Kernel are you using???

Netscape 3.51 Tomcat

[Stephan Ruetke]

Hello,

I am trying to integrate NES 3.5.1 with tomcat 3.2.1 on a winnt 4.0 
server.and I am not sure how I can test if it worked:
I followed the instructions "tomcat-netscape-howto.html",
I downloaded nsapi_redirect.dll (and did not build it).
The how-to says: start tomcat and ask Netscape for 
http://server:port/examples/
ok, maybe thats a stupid question, but I could not find an
answer to it: The Netscape server is running on port
80, but tomcat is running on 8080 - to show that the plugin works
I would have to use http://server:80/examples/ is that right?
Unfotunately the site is not found, only http://server:8080/examples/
works.

The second thing I would like to mention is that the how-to tells
the dll to be found in c:\jakarta-tomcat\bin\win32\i386\nsapi_redirect.dll, 
but in the following description
the path d:/tomcat/bin/netscape/nt4/i386/nsapi_redirect.dll
is used.

I hope you will find the time to anwer my mail.

Thanks in advance

Newbie with TomCat

[David DELGRANCHE]

Hi all,

I'm new using tomcat. I used to use Apache JServ1.2 for my application. I 
have about 70 differents servlets with about 50 users. So you can imagine 
the number of connections I can have to my Oracle DataBase.
Does anyone can tell me if Tomcat can support this use?
Do you think this is a good solution in my use case?
Thanks for help
David.

RE: Newbie with TomCat

[Benoit Jacquemont]

Hi David,

Anyway, Tomcat comes in replacement of Jserv and according to the Jakarta
Project Team, you should use it instead of JServ, which is not maintained
any more. So there is non reason to think that Tomcat is weaker that JServ,
it should be even more powerful and stable than Jserv.

aaargh!

[Michael McElligott]

Okay, so I want to hook up apache with Tomcat on my 
development box (win98). So I read server.xml, and it tells me I need to 
make these modifications to httpd.conf. Then it says: here's how you make 
mod_webapp.so.

Of course, to make mod_webapp.so, I need make, 
right? And since I'm on 98, I don't have it. That's aside from the 
fact that I need a compiler (I'm thinking gcc, right?).

So I download gcc. It has to be made as 
well. From the documentation that I went through, looks like it encourages 
you to start with Visual C++. I don't *have* Visual C++. I'm a java 
guy. I was very happy to leave pointers at school and go to a nice warm 
everything-done-for-you Java world. So then I think, well I guess I need 
to get make anyway (regardless of the VC++ question). Make has to be made 
too. Hmm..

So I spot something called egcs at one point and 
for some reason think it's an executable that will run on Intel hardware. 
Wrong. Doesn't support windows at this time.

The point of this rant is not (as you might think) 
that the universe needs to satisfy me.. it's just that I'm a little concerned 
that I need to go buy a Microsoft product to get open source software to run on 
my machine..

Just ranting at 2:15...

Mike

P.S. I do have VC around here somewhere, but 
I imagine lots of folks don't.. how do they get everything set up, without 
having to guy buy VC++?

P.P.S. I suppose the easy answer would be to 
download Red Hat, huh? ;)

RE: generating a excel page in the browser

[Danny Angus]

you cant affect this behaviour, if you want to simply display in the
browser, then your user has to have elected not to be prompted for this MIME
type.
 :-(

IE4+  Excel are quite good at picking up other file formats, such as CSV
TAB etc, and the best way of all (to get generated sheets into excel) is to
use excel as the browser, by typeing a URL into the File-Open dialogue box,
at the filename field.
Then deliver the M$ HTML format, generated by your webbapp, and you can
generate all the rich functionality of Excel workbooks, including
multiple-sheets, and VB macros.
You can create a return path functions in your macros to build up two way
traffic with the server.

Its an awsome effect when people see it for the first time.

I agree with this guy, VC++ seems a bit of a strange recommendation,
understandable in that it is the authoritative compiler for Windows, but
sits uneasily with the philosophy, and.. are non developers going to pay out
that much just to compile a slightly non-centered version of apache?

I'm not ranting, just curious.

Tomcat 3.2.1 JDK1.3.0 on Solaris - processor usage.

[Gary Lawson]

Has anyone experienced this?

Tomcat 3.2.1 with Sun's JDK1.3.0_02 on Solaris 8 64 bit on a twin processor
Sparc box.

Under certain circumstances (regularly but not consistently) our webapp
causes the processor usage of the java process on one processor to rise
quickly to 80% and just sit there or therabouts. Bizarrely, this figure
(80%) seemed to vary. Sometimes it would be 80, sometimes 90 and originally
with Tomcat 3.2 beta8 it was 100%. Restarting Tomcat (and hence the JVM)
always solved it.

Our root context is configured correctly, so we knew it wasn't the known
processor usage bug.

We patched Solaris, the JDK and brought Tomcat to 3.2.1 with no success.
Eventually we rolled back the JDK (and hence the JVM) to V1.2.2_07 and this
solved it.

As an aside can anyone point me towards some documentaion about getting the
JVM to use both processors? Please bear in mind I am the Tomcat/Solaris guy
NOT the webapp developer!

Bug: Static access to not packaged class

[Andrew]

 Hi, I think there is some bug 
with access to not packaged classes in tomcat4B2/B3 in B1- seems all 
ok.
I have some not packaged class( without package 
defined)under WEB-INF\classes\Locals.class, when I try to access 
static members of it from .jsp
I've got compilation error- Locals class or field 
name is undefined...
What's the problem?

Thank you.

tomcat + apache URL rewriting

[Sebastian Hauer]

Hi tomcat users,

I want to use url rewriting for my session management.
It works nicely with cookies enabled using tomcat standalone on port
8080 and in combination with apache. I encode all used url's in my
servlets though and using tomcat standalone even the url rewriting works
nicely but it does not if I try to connect over apache. So I think it
has to do something with my apache setup. 
I have mod_rewrite loaded.
Does anyone know what I'm doing wrong?

Here is my setup:
SuSE Linux 7.1 with a 2.4.2 kernel
apache 1.3.14
tomcat 3.1 with mod_jserv
sun's java 1.2.2

Thanks,
Sebastian

Problem with request parameter in UTF-8 (Unicode)

[Frank Peters]

I have a JSP page including a form, all encoded in UTF-8, which
reaches the requesting browser just fine. The browser then submits the
form (GET or POST, same problem) to another JSP page on the same
server. When I try to read the request parameters via
request.getParameter("somename"), I receive garbage for every
character in the form fields not in the standard ASCII charset. The
request.getCharacterEncoding() function returns null.

I seems to me the received parameters are converted from ISO 8859-1 to
UTF-8 by Tomcat, though they already are encoded in UTF-8. Am I
missing a configuration setting, like some sort of default character
encoding? I have looked through loads of docs and the config files
themselves, but I did not find anything (except for the
"file.encoding=UTF_8" which I needed for sending the unicode pages).
I would appreciate any help.

TIA,
Frank Peters

Servlet autoreloading troubles ...

[Laurent LAUBIN]

Hello everybody

I have some questions about tomcat 3.2  servlet reloading :

I have a context for development with reloadable="true", I put all the
.class in the WEB-INF/classes of this context.

If the .java are not in the same directory, it looks like servlet reloading
doesn't work ...

Moreover, if I delete the classfile of the servlet, I still can access it
until I restart tomcat ... (And it's not a problem of my navigator's cache
:)

So what are the rules for the servlet auto reloading ??? How can I unload
servlet from the server without restart it ?


For information, server is RedHat 7.0 with Apache 1.3.12/ModSSL2.6.6  and
Tomcat 3.2.1 with JDK1.3 from sun ;)



Thanks in advance,

Im trying to let PWS 4.0 work together with Tomcat 3.2 under NT 4.0.

I think the isapi_redirect.dll is properly configured but I alway get the

Dates in Java

similar object)

I have a mySQL table with aDATETIME cell. I 
want to get the date from this cell

(formatted like so: e.g. 2001-03-23 
13:04:59)

and retrieve the date that is exactly 7 days 
earlier than the retrieved date.

What is the easiest way to do this? I noticed a lot 
of method deprecations in the specs and I am having trouble using the Date 
object.

TomCat installation

[David DELGRANCHE]

Hi all,

I've just downloaded TomCat 3.1.1 to use it on Solaris and on Windows too. 
It seems there is no installation instructions. So I have several 
questions:
- How do I have to specify to Apache Server to workwith TomCat?
- It seems there is a web.xml file in which they have put some servlets 
caracteristics. Do I have to put in it all the informations on my servlets? 
How do I have to install TomCat?

thanks for help

David.

First, in regards to displaying your date use the java.text.DateFormat
class(note DateFormat
is abstract so of course you'll want to use one of the 'implementation'
classes).  Since
java.sql.Date extends java.util.Date you can of course use the
java.text.DateFormat classes
to format a java.sql.Date.

Secondly, the problem you are having using java.sql.Date could be if you are
importing java.util.*.  This will import java.util.Date in addition to
java.sql.Date.
Therefore, when you code Date d = new Date() the compiler doesn't know which
classdef
to use.  One solution to to not import anything using splay(*).  This is the
way we
do it.  You import block may get a little large but it also makes it easier
for other
developers to figure out where to look for source.  Another is to code it as
java.sql.Date d = new java.sql.Date();

RE: Dates in Java

[Erik Barke]

Yo!

You 
could try solving the problem by selecting the date column - 7 in 
the
sql 
query, i.e. 'select date_column -7 from foo_table'. It's been a long 
time
since 
I last used MySql, but I know for sure that it works in M$ Sql Server 
:)

Regarding the Date() problem, there is no constructor 
matchingDate() in java.sql.Date.
(At 
least not in Java 2 1.3) There is, however,such a constructor 
in java.util.Date. Or you
could 
try using another constructor in java.sql.Date...

Cheers 
:)

You got to explicitly tell which Date object you want to use:

ex.: java.util.Date d = new java.sql.Date((Long)l);

You can also look at the java.text.SimpleDateFormat class:

java.lang.Object

This is the way I would do it, which will allow it be

Calendar c = Calendar.getInstance();
c.add(Calendar.DATE,-7);

//Connection is assumed
PreparedStatement stmt = conn.prepareStatement("select
* from sometable where somedatetimefield = ?");
stmt.setTimestamp(1,new
Timestamp(c.getTime().getTime()));

  is abstract so of course you'll want to use one of the 'implementation'
  classes).  Since
  java.sql.Date extends java.util.Date you can of course use the
  java.text.DateFormat classes
  to format a java.sql.Date.
 
  Secondly, the problem you are having using java.sql.Date could be if you
are
  importing java.util.*.  This will import java.util.Date in addition to
  java.sql.Date.
  Therefore, when you code Date d = new Date() the compiler doesn't know
which
  classdef
  to use.  One solution to to not import anything using splay(*).  This is
the
  way we
  do it.  You import block may get a little large but it also makes it
easier
  for other
  developers to figure out where to look for source.  Another is to code
it as
  java.sql.Date d = new java.sql.Date();

RE: Servlet autoreloading troubles ...

[Benoît Jacquemont]

Hi,

Servlet reloading is an alpha feature and it is known to doesn't work in
many cases. You have to restart Tomcat each time you build a .class.

Benot

 Hello everybody

 I have some questions about tomcat 3.2  servlet reloading :

 I have a context for development with reloadable="true", I put all the
 .class in the WEB-INF/classes of this context.

 If the .java are not in the same directory, it looks like
 servlet reloading
 doesn't work ...

 Moreover, if I delete the classfile of the servlet, I still
 can access it
 until I restart tomcat ... (And it's not a problem of my
 navigator's cache
 :)

 So what are the rules for the servlet auto reloading ??? How
 can I unload
 servlet from the server without restart it ?


 For information, server is RedHat 7.0 with Apache
 1.3.12/ModSSL2.6.6  and
 Tomcat 3.2.1 with JDK1.3 from sun ;)



 Thanks in advance,

 Objet : Error 404 running isapi with PWS 4.0 and Tomcat 3.2





 Hi all ,

 Im trying to let PWS 4.0 work together with Tomcat 3.2 under NT 4.0.

 I think the isapi_redirect.dll is properly configured but I
 alway get the

 but I didnt find any new hint.

 The isapi.log looks like this when Im trying to acces the url
 "http://localhost/examples/jsp/index.html":

Re: Dates in Java

On Fri, 6 Apr 2001, Ryan wrote:

 I have a simple question about the Date object (or similar object)

 I have a mySQL table with a DATETIME cell. I want to get the date from this cell

 (formatted like so: e.g.  2001-03-23 13:04:59)

  and retrieve the date that is exactly 7 days earlier than the retrieved date.

 What is the easiest way to do this? I noticed a lot of method deprecations in the 
specs and I am having trouble using the Date object.

First off, when dealing with dates related to SQL calls, always use the
setDate() and getDate() functions of the PreparedStatement and ResultSet
respectively. These will format the date correctly for the underlying
RDBMS and they take and return a java.sql.Date. Note that a java.sql.Date
is different from a normal java.util.Date. You will need to use these full
class designations in your code to distinguish them.

To get a date that is 7 ddays prior use the Calendar class. Use
getInstance to get a Claendar instance. Set the Calendar's time to the
original date then do a cal.add(cal.DAY_OF_MONTH, -7) (where cal is the
name of your Calendar object). Note that I don't have the docs in front of
me right now, so that might not be exaclty the syntax.

Has anyone experienced this?

Tomcat 3.2.1 with Sun's JDK1.3.0_02 on Solaris 8 64 bit on a twin processor
Sparc box.

Under certain circumstances (regularly but not consistently) our webapp
causes the processor usage of the java process on one processor to rise
quickly to 80% and just sit there or therabouts. Bizarrely, this figure
(80%) seemed to vary. Sometimes it would be 80, sometimes 90 and originally
with Tomcat 3.2 beta8 it was 100%. Restarting Tomcat (and hence the JVM)
always solved it.

Our root context is configured correctly, so we knew it wasn't the known
processor usage bug.

We patched Solaris, the JDK and brought Tomcat to 3.2.1 with no success.
Eventually we rolled back the JDK (and hence the JVM) to V1.2.2_07 and this
solved it.

As an aside can anyone point me towards some documentaion about getting the
JVM to use both processors? Please bear in mind I am the Tomcat/Solaris guy

pageContext from a bean?

[Dave Weis]

Is it possible to access the pageContext from inside a bean without
passing it in? More specifically, I need to access the request object.
I've tried referencing pageContext by itself with no luck and I've also
done this

JspFactory  factory = JspFactory.getDefaultFactory();
PageContext pageContext = factory.getPageContext(null, null, null, null,
true, 8192, true);

HttpServletRequest incomingRequest =
(javax.servlet.http.HttpServletRequest)   
 pageContext.getRequest();

Thanks for any help

RE: Scope of Mailing List (was RE: Dates in Java)

[Michael Wentzel]

 Are we in the tomcat-user forum ??? 
 I don't see the relationship between a so simple constructor problem
 (which Javadoc solve quiet easily ...) and Tomcat ...

I agree that this list is not the place for this question(the proper
place would be java.sun.com JDC groups) but most of the time it is
faster and simpler to just answer the questions and get it off the list.

Here's a somewhat basic guideline for good posting:
* Evaluate scope of question(if it doesn't correlate directly to tomcat
 don't post it here).  An example would be:
  - Using java.sql.Date doesn't really belong in tomcat-user.
  - Using DB Connection Pooling with Tomcat does belong here.
* First check archives(link can be found tomcat website).
* Then post it if you still have a question.
(Another good guideline is... Please post in plain text.  Not HTML, etc.)

Please see my 3rd paragraph. The readme was the first place I looked. I am
aware of this bug. It is not what caused our processor usage to spiral.
Perhaps I should have said "all our contexts/webapps are configured

RE: TomCat installation

[Benoit Jacquemont]

Hi David,

There's really good documentation with the Tomcat 3.2.1 distribution:
howto-tomcat et howto-tomcat-apache. I use these well-written to build my
systems based on Tomcat and Apache, and they're work great.

Anyway, since Tomcat is a Java program, you just need to copy it into a
directory and expand all the file and directory from the tar.gz.
Then set the JAVA_HOME environment variable to your java path (for example:
/usr/local/jdk1.3), and use the startup.sh/bat script which is in the
TOMCAT_HOME/bin directory. Sometimes, on Windows, you need to start once the
tomcat_env script before starting tomcat to set all the environment
variables...

   Hi all,

   I've just downloaded TomCat 3.1.1 to use it on Solaris
 and on Windows too.
 It seems there is no installation instructions. So I have several
 questions:
   - How do I have to specify to Apache Server to workwith TomCat?
   - It seems there is a web.xml file in which they have
 put some servlets
 caracteristics. Do I have to put in it all the informations
 on my servlets?
   How do I have to install TomCat?

   thanks for help

   David.

OutputStream Already in USE ..!!!!

[Lakshmeenrayana]

I am using Tomcat and trying to write a Gif file to 
client browser window using JSP.
I use ACME - GifEncoder to convert the picture to 
GIF.
The Encoder needs OutputStream type object as one 
of the parameter in its constructor.
Iam using ServletOutputStream object for 
this, which i got through response.getOutputStream().

But the tomcat gives Error as "OutputStream already 
been used."

But the GIF image is Displayed properly in IE 
5.0.

It gives ASCII charactes in Netscape.

Why is this so.

Please help.

[Benoît Jacquemont]

  
  I don't know why you get a OutputStream already in use, 
  butthereason whyit works with IE and not with Netscape may 
  be because you do not setproperly the Content-type 
  ofyourimage. Indeed, IE seems to be a little bitcleverer 
  than Netscape because it interprets the real content of a file before 
  displaying itinstead ofonly looking at the Content-type header 
  property. So you have to be more explicit with 
  Netscape.

--
The OutputStream already in use is because the automatically generated code
in a jsp class file
gets the output stream as a JSPWriter therefore when getOutputStream() is
called it thinks there
is already an 'external lock' of this resource object and doesn't think it
can use it.

Apache + Tomcat Configuration

[Zhengan Cai]

Hi, everyone:

I am trying to setup Apache + Tomcat to run JSP and Servlets on Win. 2000. I
am using Apache 1.3.19, and Tomcat 3.2.1.

I created my own directory in
%TOMCAT_HOME%/webapps/mytest, copied the structure from
%TOMCAT_HOME%/webapps/examples such as WEB-INF, META-INF I put my
servlets .class files in the ../mytest/WEB-INF/classes/aaa.class.

I did some configurations in Tomcat: Server.xml, Tomcat-Apache.conf,
Tomcat.conf; and in Apache: httpd.conf

Now I can use Apache + Tomcat to run my JSP files, BUT I can  ONLY  run  the
system provided  sample Servlets files. I CAN'T run my own Servelts files no
matter where I put the .class files.

Could you give me a help for the configuration as my assignment is almost
due  ?

Thank you very much for your time and concern.

Subject:mod_jk under darwin (OS X)

Hi all,

I'm trying to get mod_jk to compile under OS X but it seems that it relies
on glibc - which is not (yet?) ported to Darwin.

Does anybody know if this happens to be the case and if so is there any
other way to get mod_jk to compile?

Cheers,

   I have a simple question about the Date object (or similar object)
  
   I have a mySQL table with a DATETIME cell. I want to get the date from

   -
   For example,

   Date d = new Date();

   First, in regards to displaying your date use the java.text.DateFormat
   class(note DateFormat
   is abstract so of course you'll want to use one of the 'implementation'
   classes).  Since
   java.sql.Date extends java.util.Date you can of course use the
   java.text.DateFormat classes
   to format a java.sql.Date.
  
   Secondly, the problem you are having using java.sql.Date could be if you
 are
   importing java.util.*.  This will import java.util.Date in addition to
   java.sql.Date.
   Therefore, when you code Date d = new Date() the compiler doesn't know
 which
   classdef
   to use.  One solution to to not import anything using splay(*).  This is
 the
   way we
   do it.  You import block may get a little large but it also makes it
 easier
   for other
   developers to figure out where to look for source.  Another is to code
 it as
   java.sql.Date d = new java.sql.Date();

RE: Apache + Tomcat Configuration

Dear Michael,

I just reach the TomCat mailing List this morning and even if I'm using

What is exactly your role on this list? Trying sharing knowledge like a lot 
of people or just controlling all the mails that are posted? It seems that 
you have nothing else to do than being boring with people. A mailing list 
is something alive. Even if there can be mails that doesn't match exactly 
the subject, a lot of people could find them interesting.
Hope people on this list are more open-minded than you are!

simple question for servlet-configuration of tomcat

Hello,

since several weeks I am testing tomcat as a Servlet Engine with great
success. I use Win98 SE2 with PWS.
Now I have a simple problem (I think):

What I have to do (in the configuration files) when I want to start my
servlets with the URL:

http://localhost/servlet/TestServlet

and not with a WEPAPP-Directory like
http://localhost/example/servlet/TestServlet

Which settings I have to do in the configuration-files and in which
directory I have to put my Servlets ?

Thanks a lot for your answer

I don't know why you get a OutputStream already in use, 
butthereason whyit works with IE and not with Netscape may 
be because you do not setproperly the Content-type 
ofyourimage. Indeed, IE seems to be a little bitcleverer 
than Netscape because it interprets the real content of a file before 
displaying itinstead ofonly looking at the Content-type header 
property. So you have to be more explicit with 
Netscape.

I am using Tomcat and trying to write 
a Gif file to client browser window using JSP.
I use ACME - GifEncoder to convert the picture 
to GIF.
The Encoder needs OutputStream type object as 
one of the parameter in its constructor.
Iam using ServletOutputStream object for 
this, which i got through response.getOutputStream().

But the tomcat gives Error as 
"OutputStream already been used."

But the GIF image is Displayed properly in IE

It gives ASCII charactes in

Why is this so.

RE: simple question for servlet-configuration of tomcat

[Benoît Jacquemont]

Please look at the answers after posting a question. I have already answered
to your question yesterday:

 Hi,

You just have to declare a context like this:
Context path="" docBase="/path/to/myapp" debug="0"
reloadable="false" 
/Context
in your TOMCAT_HOME/conf/server.xml. You should also remove the ROOT
context and the ROOT directory that is in the webapp
directory.
Anyway, in real world, I mean in production environment, you should remove
all the contexts that don't deal with your app,
and all the subdirectory within the /webapp.

tomcat startup problem

[Adilakshmi Lingam]

Hi,

I have tomcat 3.2.1 running on win 2k with jdk 1.3

Everything was running perfectly until a while ago. Suddenly when I see,
tomcat is shutdown and all the windows are closed. I tried to restart.
Tomcat starts opening in the new window. I think it loads the loadon startup
servlet and then when it comes to  PoolTcpConnector, the window is closed
and tomcat is shut down. I'm not sure, if the problem is at PoolTcpConnector
or not. I can't see that. It just closes down.

I can't see any tomcat.log files.

Can someone please answer this asap. I'm kinda in a big fix.

RE: OutputStream Already in USE ..!!!!

Usually, you don't set the Content-Length because that's generated pages,
and if you set a Content-Length higher than the real size of the generated
gif, I don't know how IE or Netscape will react... But you can try it. I
think you just have to set the Content-Length the same way you set the
Content-Type.

Hope that'll help.

Enabling Episode Accountability in IP Service Creation

RE: XSLT vs. JSP

[Samson, Lyndon [IT]]

Well actually in the context of generating web applications, XSLT and JSP
are both competing.

IMHO, XSLT has the huge advantage of separating content and format, unlike
JSP.

XSLT is also turing complete, I would think for many applications it would
be a much better 
solution than Perl/LineNoise :-)

Re: Dates in Java

[Alvin Yap]

I think you need a java.sql.Timestamp type as compared to java.util.Date type
To create new timestamp or

long time = System.currentTimeMillis();
Timestamp currentTime = new Timestamp( time );


...
This object will hold the date and time.  If you want to format the time
differently use Calendar and Formatter to achieve this.

I don't think this is necessarily correct in all circumstances.

Try as I might I can't get any of the automatically generated files to reflect that I 
want to access my servlets at
/webapp/servletalias
rather than at /webapp/servlet/servletalias

I did succeed in making this work with tomcat and apache by editing my tomcat.conf 
file as follows:

Alias /webApp "C:/ApacheGroup/Tomcat/webapps/webApp "
Directory "C:/ApacheGroup/Tomcat/webapps/webApp "
Options Indexes FollowSymLinks
/Directory
ApJServMount /webApp /webApp

Using the Host directive (Feature request?)

[Jeff Kilbride]

Is there any plan to include pattern matching in the Host directive in the
server.xml file? Right now, in order to catch requests to mydomain.com and
www.mydomain.com, you have to use two Host directives. The problem with
this is that it loads two instances of all your servlets/jsp's. I'm using DB
connection pools and I'd like to avoid loading everything twice -- creating
twice as many connections to my DB.

Something like:

Host *.mydomain.com

or even being able to list multiple combinations, to avoid pattern matching:

Host mydomain.com www.mydomain.com

would really help. I'm using 3.2.1 and haven't tried any of the betas, yet.
Is this available in 3.3 or 4.0?

Thanks,

??? Does Tomcat 4 b3 Support Reloading ???

[Tony LaPaso]

Hello,

By reading the documentation, it seems Tomcat 4 b3 should support servlet
reloading but this does not seem to be the case.

After a fresh install of Tomcat 4 b3 I modified the SnoopServlet and the
change was *not* picked up even though the examples Context has
reloadable="true" specified.

Has anyone else had this problem?

Is there a version of Tomcat that *does successfully reload changed
servlets?

Thanks.

Servlet Contexts and sessions

[Andy Mauro]

Hey all.

This is sortof a JSP/Servlet related question, but it falls within the scope
of this forum:

Can someone give me a compelling reason why sessions cannot be shared across
contexts? I realize this is part of the Servlet 2.2 spec, and not strictly
speaking a tomcat issue, but perhaps there is a way to work around this
limitation in tomcat?

I can't think of a good reason for disallowing session sharing between
contexts. Ideas?

Thanks in advance,

Hi :-)   from my work, I also can not auto-reload MyServlet with

Problems with caching?

[Melissa Matthews]

Title: Problems with caching?





Does anyone know if there is a problem with regular HTML files being somehow cached by Tomcat 3.2.1 on Solaris 2.8? I have replaced 

some HTML header pages, but I still see the old ones. I have searched and can not find those files anywhere. If I go 
directly to an shtml file that includes the HTML header files, it shows the new header, but the JSP pages always show
the old headers. I tried renaming the header to another name and then the JSP page showed the new header.


I have deleted all of the pages from the work directory.


Any suggestions? Thanks in advance.

Apache+Tomcat+vhosts insights, discussion (long)

[Scott Tatum]

I too had the utilization problems associated with Apache and Tomcat
3.2.1. Actually, the problem also manifests itself in Tomcat standalone.
After researching the problem and eventually coming up with a solution,
I realized a couple of things that I have not seen posted to the list,
so I thought I would share them and possibly help some others out.

First of all let me explain my setup. Our group does a lot of Intranet
applications for different groups and we have recently moved from JRun 3
to using Tomcat 3.2.1 for our servlet container. And I must say, even
though the initial setup and administration was tedious, Tomcat is a
faster, more stable environment for us. Our development environment is a
PC running RH6.2, and our production boxes are usually running some
version of Solaris, and in this particular case, Solaris 8. Both setups
are using Apache1.3.19+Tomcat 3.2.1 and Java SDK 1.3.0_02. We run
separate VM's for each virtual host/application.

Our production boxes typically hold several production websites, each
with their own virtual host. The name of the production box itself
doesn't host a site, just the CNAME's we have registered for that host.
For example, the production server may be called pserv, with aliases
app1, app2, app3, etc. We don't have (or want) a website called
pserv.wcomnet.com (wcomnet.com is our Intranet domain), but we do have
the websites app1.wcomnet.com, app2.wcomnet.com, etc. I don't know how
representative this is of people using Apache+Tomcat and virtual hosts,
but it is a good fit for us, and Tomcat handles it well.

The configuration files  look something like this:
-workers.properties-
worker.list=app1-ajp12, app2-ajp12, app3-ajp12

worker.app1-ajp12.port=8000

Re: Problems with caching?

[Scott Tatum]

Are you using the include file directive to include the files? If you
are, then that is the problem. JSP's won't recompile if a file they
include is updated, only if the jsp file itself is updated. There are
two ways to get around this:

1. Load the jsp file and save it (may have to add a space, remove it,
then save or something similar)
2. Use the touch command unix to update the timestamps on all your jsp
files. This will cause them all to recompile. (e.g. go to your dir with
the jsp's and do a "touch *.jsp") This might be preferable since you are
dealing with header includes.

Hope this helps.

Servlet auto-reloading under ROOT context (was RE: simple question for servlet-configuration of tomcat)

[Joel Parramore]

On a slightly related note: are servlets under the ROOT context
automatically reloaded?

The docs in server.xml would appear to indicate that reloadable="true" is
the default, but there's no entry for the ROOT context in my server.xml
file, and it appears to be inconsistent on our server with regard to
reloading a servlet which has (definitely) changed in
webapps/ROOT/WEB-INF/classes (i.e., Tomcat apparently reloaded the servlet
each time the class was changed, then suddenly stopped doing so, with no
configuration changes made).

Would placing an explicit CONTEXT entry for the ROOT in the server.xml file,
i.e.,

Context
path="/"
docbase="webapps/ROOT"
crossContext="false"
debug="0"
reloadable="true"
/Context

resolve this issue?  Has anyone else encountered a similar problem?

I can supply more configuration upon request, but at least I'll note that
the server configuration is with Apache 1.3.14 and Tomcat 3.2.1 running
Redhat Linux 7.0 on an Intel box, JDK 1.2.2.  Tomcat, aside from slight
changes for mod_jk operation with Apache, is unchanged from the default
configuration.

Joel Parramore

Tomcat Sessions

Hi ,
We are running tomcat 3.2.1 on WinNT with Apache Server 1.3.12, and
here is the problem that we are facing with Session:
"HttpSession session = getSession(req)"
where req is the HttpServletRequest object.
is working fine with ServletRunner (provided by Jsdk2.0)
but when we start using it with Tomcat,
the session object is of type as follows:
HTTP Session = org.apache.tomcat.facade.HttpSessionFacade@8f04cf35
Is there any difference in : Jsdk2.0 HttpSession Object 
the above one

it seems that we get NULL object in Tomcat.
Please help me out in solving this problem...

 Subject: RE: Dates in Java

 I have a simple question about the Date object (or similar object)

 I have a mySQL table with a DATETIME cell. I want to get the date
 from
   this
 cell

 (formatted like so: e.g.  2001-03-23 13:04:59)

  and retrieve the date that is exactly 7 days earlier than the
 retrieved
 date.

 What is the easiest way to do this? I noticed a lot of method
   deprecations
 in the specs and I am having trouble using the Date object.
 -
 For example,
 DateTest.java:20: cannot resolve symbol
 symbol  : constructor Date  ()
 location: class java.sql.Date
 Date d = new Date();
  ^
 1 error

 -

   
  
  --
   --
 -
 First, in regards to displaying your date use the
 java.text.DateFormat
 class(note DateFormat
 is abstract so of course you'll want to use one of the
 'implementation'
 classes).  Since
 java.sql.Date extends java.util.Date you can of course use the
 java.text.DateFormat classes
 to format a java.sql.Date.

 Secondly, the problem you are having using java.sql.Date could be if
 you
   are
 importing java.util.*.  This will import java.util.Date in addition
 to
 java.sql.Date.
 Therefore, when you code Date d = new Date() the compiler doesn't
 know
   which
 classdef
 to use.  One solution to to not import anything using splay(*).
 This is
   the
 way we
 do it.  You import block may get a little large but it also makes it
   easier
 for other
 developers to figure out where to look for source.  Another is to
 code
   it as
 java.sql.Date d = new java.sql.Date();

Re: Superclass for JSPs?

[Peter Smith]

I honestly don't know if it's possible to subclass
your JSP pages, but I may have a hack workaround. 
First, know that you can declare a 'jspinit()' method
that is just like the 'init()' method in your servlet.
 Search the following doc for details:

http://developer.java.sun.com/developer/onlineTraining/JSPIntro/contents.html

Also, you might use the 'include' directive to include
a jsp file in all of your other jsp pages.  For
instance, you may write a 'init_and_utils.jsp' file
and use the jsp include directive to attach it to each
of your other jsp's.

jsp:include page="init_and_utils.jsp"/

  Subject: RE: Dates in Java
 
  I have a simple question about the Date object (or similar
object)
 
  I have a mySQL table with a DATETIME cell. I want to get the
date
  from
this
  cell
 
  (formatted like so: e.g.  2001-03-23 13:04:59)
 
   and retrieve the date that is exactly 7 days earlier than the
  retrieved
  date.
 
  What is the easiest way to do this? I noticed a lot of method
deprecations
  in the specs and I am having trouble using the Date object.
  -
  For example,
  DateTest.java:20: cannot resolve symbol
  symbol  : constructor Date  ()
  location: class java.sql.Date
  Date d = new Date();
   ^
  1 error
 
  -

  -
  First, in regards to displaying your date use the
  java.text.DateFormat
  class(note DateFormat
  is abstract so of course you'll want to use one of the
  'implementation'
  classes).  Since
  java.sql.Date extends java.util.Date you can of course use the
  java.text.DateFormat classes
  to format a java.sql.Date.
 
  Secondly, the problem you are having using java.sql.Date could
be if
  you
are
  importing java.util.*.  This will import java.util.Date in
addition
  to
  java.sql.Date.
  Therefore, when you code Date d = new Date() the compiler
doesn't
  know
which
  classdef
  to use.  One solution to to not import anything using splay(*).
  This is
the
  way we
  do it.  You import block may get a little large but it also
makes it
easier
  for other
  developers to figure out where to look for source.  Another is
to
  code
it as
  java.sql.Date d = new java.sql.Date();

RE: Tomcat Sessions

[William Kaufman]

  Is there any difference in : Jsdk2.0 HttpSession Object  the 
  above one 
org.apache.tomcat.facade.HttpSessionFacade IS an 
HttpSession.

  So whenever we try to access the current session object, it 
  seems that we get NULL object in Tomcat. 
I don't know what getSession(HttpServletRequest) is--it doesn't seem to 
be in the JSDK 2.0.
You should call HttpServletRequest.getSession() -- if you still 
have trouble, the problem is somewhere else. You should check where that 
stack trace is coming from.

Re: Servlet auto-reloading under ROOT context (was RE: simple question for servlet-configuration of tomcat)

[Tony LaPaso]

I have a *similar* problem. None of my servlets are being reloaded using
Tomcat 4, b3. This includes the servlets in /examples context.

The only way I've been able to get servlets to reload (aside from
re-starting Tomcat) is to run /manager/reload?path=/someContext.

Apparently servlet reloading is completely broke in T4 b2/3.

Subject: Servlet auto-reloading under ROOT context (was RE: simple question

 On a slightly related note: are servlets under the ROOT context
 automatically reloaded?

 The docs in server.xml would appear to indicate that reloadable="true" is
 the default, but there's no entry for the ROOT context in my server.xml
 file, and it appears to be inconsistent on our server with regard to
 reloading a servlet which has (definitely) changed in
 webapps/ROOT/WEB-INF/classes (i.e., Tomcat apparently reloaded the servlet
 each time the class was changed, then suddenly stopped doing so, with no
 configuration changes made).

 Would placing an explicit CONTEXT entry for the ROOT in the server.xml
file,
 i.e.,

 Context
 path="/"
 docbase="webapps/ROOT"
 crossContext="false"
 debug="0"
 reloadable="true"
 /Context

 resolve this issue?  Has anyone else encountered a similar problem?

 I can supply more configuration upon request, but at least I'll note that
 the server configuration is with Apache 1.3.14 and Tomcat 3.2.1 running
 Redhat Linux 7.0 on an Intel box, JDK 1.2.2.  Tomcat, aside from slight
 changes for mod_jk operation with Apache, is unchanged from the default
 configuration.

 Joel Parramore

   Hello,
  
   since several weeks I am testing tomcat as a Servlet Engine with great
   success. I use Win98 SE2 with PWS.
   Now I have a simple problem (I think):
  
   What I have to do (in the configuration files) when I want to start my
   servlets with the URL:
  
   http://localhost/servlet/TestServlet
  
   and not with a WEPAPP-Directory like
   http://localhost/example/servlet/TestServlet
  
   Which settings I have to do in the configuration-files and in which
   directory I have to put my Servlets ?
  
   Thanks a lot for your answer

Which workers am I using?

[Peter Smith]

I can see the ajp12 and 13 worker threads being
instantiated (via log messages in the console) when I
crank up Tomcat, but how do I know if the 13's are
being used at all?  All my auto-generated files
continue to point to 'ajp12' workers, even after I've
changed almost every reference I can find in any
properties file I can find.  Does it even matter
what's in these 'auto' files?  I'm not even sure it
matters which worker(s) I'm using, but the docs said
it did.

I've pointed Apache/Tomcat to look at a customized
version of the 'mod_jk-auto' file with most/all
'ajp12' references changed to 'ajp13'.  Is this even
necessary?  What else might I need to do?

Thank you!

Re: Which workers am I using?

[Scott Tatum]

In order to get Apache to use ajp13, you have to use your own config
files. The auto files always use ajp12. You'll need to change
workers.properties so that your workers  have a type of ajp13. I don't
think it matters what your workers are called, though most people have
the protocol as part of the worker name. It's possible that your worker
could have a name with ajp12 in it, even though its type is ajp13 and it
might make deceiving log entries that way.

Re: Apache + Tomcat configuration

[Pae Choi]

Did you put in another context entry in the server.xml file
similar to this:

Context path="/examples"
docBase="webapps/examples"
crossContext="false"
debug="0"
reloadable="true" 
/Context

(exchange "examples" with your own directory "mytest")

Hi, everyone:

I am trying to setup Apache + Tomcat to run JSP and Servlets on Win. 2000.
I
am using Apache 1.3.19, and Tomcat 3.2.1.

I created my own directory in
%TOMCAT_HOME%/webapps/mytest, copied the structure from
%TOMCAT_HOME%/webapps/examples such as WEB-INF, META-INF I put my
servlets .class files in the ../mytest/WEB-INF/classes/aaa.class.

I did some configurations in Tomcat: Server.xml, Tomcat-Apache.conf,
Tomcat.conf; and in Apache: httpd.conf

Now I can use Apache + Tomcat to run my JSP files, BUT I can  ONLY  run
the
system provided  sample Servlets files. I CAN'T run my own Servelts files
no
matter where I put the .class files.

Did you restart the TC?  --- "Just want to make sure!!!" :-)

Pae


Could you give me a help for the configuration as my assignment is almost
due  ?

Thank you very much for your time and concern.

Problem with mod_jk build

Quick question...
If I have a binary version of mod_jk.so, do I have to build it?  It said it
is already built for Linux, but I can't get apache to start when I put that
into apache's libexec directory and include the mod_jk.conf-auto.  What am I
doing wrong?  I have tried to build mod_jk, but get all kinds of errors
telling me that files do not exist.
