How do I set up virtual directories in Apache?
I used the Alias directive like:

This did not work?
Should this work if I add it to the httpd.conf file?

kill all java will kill all other java processes too.

If anyone is following this, I also have experienced this problem with
no
obvious solution in sight.

I am running IBM's JDK 1.3 for Linux and have seen this problem since
tomcat32b7 -> Catalina 4.0M5.  The magic 'killall java' seems to be the only
fix, as after the first shutdown.sh the Ajp12ConnectionHandler stops
listening
to shutdown requests.

Re: Access Log for Tomcat in standAlone mode or Running Apache with Tomcat.

I Already did that after reading the doc first time!
It just doesn't work. Tomcat is running on Mandrake 7.1,
everythings is well setup, but I receive apj12 error and mod_jk
problem... I did compile the source on the same OS version, but it didn't
change nothing realy!

It seems to be apache that doesn't recognize Tomcat!

Subject: Directory problem


Hello:

I am trying to use tomcat with apache and am having a
problem with my virtual host directory.

In my httpd.conf file, I added index.jsp to my listing
of index files:
DirectoryIndex index.jsp index.php index.html index.htm index.shtml
index.cgi

I also have the following virtual host defined:

  DocumentRoot /home/httpd/videosearch


  Options Indexes FollowSymLinks
  AllowOverride None

  Order allow,deny
  Allow from all




And I used this line to include my jakarta config file:
include /usr/local/jakarta-tomcat/conf/tomcat.conf

My tomcat.conf file is:
LoadModule jserv_module /etc/httpd/modules/mod_jserv.so


# Do not edit!
ApJServManual on
ApJServDefaultProtocol ajpv12
ApJServSecretKey DISABLED
ApJServMountCopy on
ApJServLogLevel notice

ApJServDefaultPort 8007

AddType text/jsp .jsp
AddHandler jserv-servlet .jsp

ApJServMount /examples /root



I want files with a .jsp extension to be processed by tomcat
and other files handled via Apache.

According to the virtual host directive, when I visit
http://216.65.31.3
I should get the files from /home/httpd/videosearch directory.
But, when I do so, I get the file:
/usr/local/jakarta-tomcat/webapps/ROOT/index.html\
which is not what I wanted.

Also, when I try to load the URL:
http://216.65.31.3/index.jsp
I get a 404 not found error.

This file I wanted to load was:
/home/httpd/videosearch/index.jsp
Which I know is there.

Also, If I try to load this URL
http://216.65.31.3/test.html
It loads the file /home/httpd/videosearch/test.html
which is what I wanted.

Any ideas?

Thanks,
Neil.

Dear Mike,
    It might help if you post
what kind of error you are getting,
or what happens when you try.
For me,
tomcat.sh jspc -v -d /usr/local/tomcat/work/localhost_8080%2Fcontextname
-webapp /usr/local/tomcat/webapps/myapp
works, it converts my *.jsp files to *.java files (which I
understand now contain the servlet source code).
    What I'm looking for is a
tool to convert the servlet
source code to servlet classes, using the unique-class-name generation
algorithm described in
http://archives2.real-time.com/pipermail/tomcat-users/2000-August/008481.html
so Tomcat doesn't have to do this work itself when it starts.
 
You do not have to search for any tool.
you can compile the java files using "javac"
and give a mapping in the web.xml for each contexts
ex:
say the file name is test.jsp then an entry like this in web.xml

   
   
jsp.test
   
jsp.test
    
 
   
/jsp/test
   
jsp.test
    

This is automatically done if you use -webinf -webxml options in Jspc.sh/bat
files
so all you hae to do is just  run jspc.sh/bat with the -webinf
-webxml options
 
 
 
    Is there such a tool? 
Or has anybody else run into Tomcat going into
500 server errors while trying to compile JSP pages under heavy load,

 
and if so, how did you deal with it, please?
Yours Sincerely,
Aleksey Tsalolikhin

ServerAlias'

[James Maggs]

Hi There,

I have set up Apache and Tomcat, working together through mod_jk. I'm using
virtual hosting through the  construct in the server.xml file.
However, the corresponding virtual host in apache has several server
aliases. Is there a way to add these server aliases to the server.xml file?
Currently, my Tomcat installation only serves content when requests come in
using the host specified in the  block whereas requests using
the various server aliases generate a 404 error.

Any ideas? My system: RedHat 6.2, Apache 1.3.12, Tomcat 3.2 Beta 8.

Many thanks,

-James

RE: WML Generation from JSP broken!!!!

I would say the best and cleanest way would be to have the page start with

I think this should work in Tomcat 4 (if not, I would consider it a bug in

Tomcat problem. Help!

[Panagiotis Konstantinidis]

Title: Tomcat problem. Help!





  Hello there. First of all forgive me if this is the wrong list. I guess this message could be easily posted on Apache's mailing list as well.

  Now, I am using Apache v1.3.12 and Tomcat v3.1 (for Windows). I have written a simple JSP program to open a connection with a mySQL database on the network. The thing is that everytime the line Class.for("org.gjt.mm.myswl.Driver"); is encountered, Tomcat goes off (and I get the error message "Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request"). It goes off just like that and everytime I have to start it up again manually (and everytime it goes off again). I know that this is the line that causes the problem because I have tried to take it out and everything is working fine. I have checked the database and the drivers and everything is fine. Now my question is: Do I have to configure something on Tomcat that I have not done before? Do I have to configure something on Apache? Has anybody encountered this problem before? What would be possible to cause it? I have to say here as well that I checked the Apache's error.log and I found the error message: "Premature end of script headers: c:\\.jsp. What does this mean?

  Thank you in advance.

The first thing I would recommend is upgrading to Apache 1.3.14 and Tomcat 3.2,
since these are the latest stable versions. Tomcat in particular has fixed 
a lot of
bugs since the version you're using.

>The thing is that everytime the line Class.for("org.gjt.mm.myswl.Driver");

Do you mean Class.forName("org.gjt.mm.myswl.Driver")?

Have you checked your logs? You should get more accurate information about
what's going wrong from the stdout and stderr messages that Tomcat puts out:
these may be going to your console window, or they may be going to log files
in Tomcat's log directory.

Without more specific error information, I would make a guess that it has to
do with the classpath. Your JDBC driver must be in the classpath that the
Tomcat server is using, if not Class.forName() will throw an exception, which
would cause the behavior you're seeing. Try putting the JDBC driver .jar file
in the WEB-INF/lib directory.

I´m trying to test Tomcat running with different jdk's. Everything is OK 
with IBMJava2-SDK-1.3-2.0.i386.rpm (and IBM's former ones and sun 1.2.2prev

The problem appears when I try to start Tomcat with sun or even blackdown

Can't I use 1.3.0 with Tomcat?
Any clue about it?

  You are right Kief. Thank you for that. I did not include the mysql.jar file in my classpath. I was using Apache and JRun before on Unix and everything was set up, therefore I completely forgot to add the mysql.jar file into my classpath. I assumed that it would already be there.  And the weird thing is that I did not even think that this would be the problem. Thank you one more time for your effort and time.

Premature end of script header in your case means 
something like when apache passed the request to a program/script, it had 
an abrupt end and apache didn't get the expected/required response for the 
request.
 
In 
your case the problem is with tomcat and not apache. Apache passed that request 
to tomcat and your jsp failed and hence 
you 
got the error premature end of script header.

Craig,

Is there way using RequestDispatcher or  sendReDirect()   to send a page to
particular frame.

For example.  sendRedirect("index.html" target=_top);

RE: Tomcat-mysql configuration

  Well I can tell you how my mySQL database 
works:
.
.
.
String url = 
"jdbc:mysql://isle:3306/football";
where: "jdbc:mysql" is the name of connection and the 
database. "isle" is the name of the server (you could have IP address instead of 
the name) on which the databse is and, "football" is the name of the 
database.
 
Class.forName="(org.gjt.mm.mysql.Driver");
which is the driver that must be loaded (I guess it is 
the same for all the mySQl databases - I am not entirely sure 
though)
 
Connection con = DriverManager.getConnection(url, 
"user", "password");
where "user" and "password" are the real iuser name and 
password that are used in order to grand you access to the

Re: mod_jk.so problem on Linux

I know this is going to help very little but...  Apparently when you get
the garbled message, it means the module was compiled with different
options than the calling module.  I know that is basic but that is where I
would start.  Example:  if your Apache has SSL enabled, then you must
compile mod_jk with the SSL module.

Hope that helps...

Tomcat 3.2 thread-pool

[jason]

Tomcat 3.2 allocates a thread from a pool to handle a session.
Can this pooling behavior be turned off so that threads die at the end of a 
request/response cycle? (as per the Tomcat 3.1 default)

Hello,
Does it come with Tomcat3.2. I have installed Tomcat 3.2, and Apache
1.3.12 is already installed.SO i need the mod_jk.dll which i shall place

But I am not getting the mod_jk.dll in Tomcat3.2 installation.

RE: mod_jk.so problem on Linux

[GOMEZ Henri]

The mod_jk.so was compiled with an apache using EAPI (mod_ssl).
And your apache didn't use such API.

You could see soon at http://rpmized.free.fr/ the announce 
of tomcat 3.2 & tomcat-mod 3.2 RPM ;-)

Unfortunately it's the browser which decides which frame to load a page
into, you can't force it on the server side. So a servlet or JSP page can't
decide to load itself into a particular frame any more than a plain HTML
page can decide to load _itself_ into a particular frame.

So if your sendRedirect("index.html") is in myServlet, the HTML which contains
the link tag that loads the original URL has to specify the frame to load 
it in:

click

Whatever output myServlet generates, even if it's a redirect, will show up in
the top frame.

A technique to get better control over your framesets is to load a frameset
which is a JSP page, and give it some parameter which will tell it what to
load in each frame. All of your links will contain target="_top", and the 
entire
frameset is loaded:

sendRedirect("smart_frameset.jsp?main=index.html&nav=nav.html");

Your smart_frameset.jsp checks its parameters and writes its frameset tags
accordingly to load the correct URL in each frame. It's not terribly efficient,
since you're reloading the whole frameset whether you need to or not.

apache + tomcat3.1 - same root dir

[Fulton CR (Charles)]

Hello, 

I'm trying to setup apache + tomcat3.1. 

Right now I have apache's DocumentRoot set to $TOMCAT_HOME/webapps, thinking
that things might be easier if both had the same document root. Although, by
default tomcat's "" context is set to $TOMCAT_HOME/webapps/ROOT right?

I did noticed that everying in this directory now has a context created for
it, e.g. "images" context, etc. Is this a problem?

I was just wondering what people were doing in the "real world" with similar
setups.

Up to this point we have just been using tomcat standalone. 

thanks,

Thread handling question

[Kai Müller]

Hi,

I try to understand how Tomcat 3.1 handles requests. I made the
following test:

I send a large amount of requests (JavaScript reloads, 5 per second over
a period of several minutes) from one user to Tomcat.

Result WITHOUT ThreadPool (SimpleTcpConnector):
the number of java processes (threads) increases. If I don't stop the
server crashes. If I stop after a while Tomcat needs some time to
regenerate respectively to work off the threads. Then I can continue.

Result WITH ThreadPool (PoolTcpConnector):
the number of java processes doen't increase to nirvana. If the limit is
adapted (on my 166 MHz ;-) max_threads=15 is ok) Tomcat does not crash.
But: when I stop the requests it needs nevertheless some time to
regenerate. Why? Does it kill the threads then and my PC is too slow? I
thought, all threads are killed immediately if there are more than
max_threads. After a while I can continue.

Can someone explain me in easy words these behaviours? Thank you.

What about Tomcat 3.2 (announced today) and thread pooling? Is it
similar?

j_security_check mapping

Thanks, Juergen

I am using Tomcat 3.2b6 with mod_jk. When accessing
http://localhost:8080/examples/jsp/security/protected/index.jsp
The login.jsp page works (posts) fine. However, when
accessing through Apache,
http://localhost/examples/jsp/security/protected/index.jsp,
the login.jsp comes up but j_security_check is not
found when I post. Has anyone else had this problem?
Can I manually do the mapping from within web.xml?

When the line Connection con = DriverManager.getConnection(url, user, password); is encountered then Tomcat just goes off (and I get the error message from Apache "Internal Server Error."). Just like that, with no error messages or anything. This is really weird because I have downloaded and installed the latest versions of both Apache (v1.3.14) and Tomcat (v3.2) and I have included the JDBC driver .jar file in my classpath.

  I have looked in the "tomcat.log" file and there are no error messages. I have looked in the "error.log" file in the Apache directory and I get the error message (for one more time): [Thu Nov 30 17:47:39 2000] [error] [client 192.168.0.25] Premature end of script headers: c:/work/tomcat/jakarta-tomcat-3.2-b7/webapps/panos/myFile.jsp. I cannot think of anything to do so if somebody knows more about that please help.

Not finding index.html file

[Neil Aggarwal]

Hello:

I am using tomcat 3.1.

I create a directory for my web application in the web apps directory.

When I got to /myapp/index.html, I get the index.html file, but
when I go to /myapp, I get a 404 not found.

Apache does load index.html files for other directories.

Does tomcat load index.html files?  If so, how do I configure it
to do so?

Thanks,
Neil.

Tomcat 4.0-m4 (and earlier) did not support connection to Apache.  It only runs in
stand-alone mode.

The code to connection Tomcat 4.0 is being actively developed, and is planned to be
included in a "milestone 5" release shortly.

You only need it if you want to look at the sources for the API classes found in
"servlet.jar".  The Tomcat distribution includes the executable version of
"servlet.jar" that you can use to compile your servlets with.  It is also used
when you run Tomcat.

When processing a servlet request, simply call

and you can use this value to construct an absolute URL.

There is not such a servlet in any current distribution of Tomcat.  If someone

Tomcat does not currently have any support for .jhtml files.  It would seem
feasible to write such a thing, and anyone interested is invited to submit it
for possible inclusion in some future version of Tomcat.

Solaris binary for mod_jk.so

[Jonathan Eric Miller]

First off, I would like to congratulate the Tomcat developers for the
release of 3.2. You guys are doing a greate job and I look forward to using
it.

One thing that I think would be very helpful to users is if you could
provide binaries for mod_jk. I'm guessing it's just a matter of resources
and not having developers around that can make these binaries. From what I
remember, there used to be Solaris binaries awhile back. Then, Solaris
seemed to be dropped in favor of Linux. I just wanted to make a point that
there are probably still a lot of Solaris users out there that might
appreciate have a binary as well.

I'm going to try to build it right now. It's been a few months since I last
did this. At that time I found that the instructions had improved a bit
which I really appreciated. I had major problems building mod_jserv
previously, due to pretty much non-existent or incorrect documentation.

BTW, I'm hoping at some point to no longer have to use Apache Web Server at
all and instead just use Tomcat in stand-alone mode. However, there are a
few issues that I need to resolve first. One issue is that I want to limit
SSL connections to using 128-bit encryption and not 40-bit or 56-bit. I'm
not sure if this is possible with Tomcat.

I have not had a chance to post all of the pre-built versions of the native code
modules yet.  In the mean time, you can use the mod_jk.dll file from 3.2-beta-8,
but there has been at least one bug fix since then, so you will want to update

TomCat and Apache

[William Colls]

In getting my Tomcat-Apache set to work, I need to create another alias
in the tomcat-apache.conf file. However, modifying this file by hand
seems a bad idea since it is regenerated at each tomcat startup. Where,
(server.xml, web.xml, somewhere else) and in what form can I put this
information, so that it will get picked up, and included in the
tomcat-apache.conf file each time it is created?

TIA.

Not with the standard PoolTcpConnector that is used.  You could switch to using the 
SimplePoolConnector -- but I doubt it has had very
much testing lately.

Also, why would you want this?  Recycling the threads in the pooled connector is one 
of the reasons that Tomcat 3.2 has better
performance than 3.1.

If you are creating hyperlinks that start with "/" then you *do* need the
context path added on the front.  This is because the browser will interpret
such a URL as being relative to the server's document root.

If you use relative URLs, though (not starting with "/"), then you do *not* want
to add the context path.  For example, if you have a page "index.html" that
wants to create a link to a page "display.html" in the same directory, simply
write:

The Display Page

response.sendRedirect() converts relative URLs back to absolute ones (adding the

although not every servlet container actually does it.

Servlet in the middle... in the middle.. in the middle

[Bragg, Casey]

Is there a way to do the following?

Let's say a user requests /foo/junk.gif, or /foo/test.jsp.

I'd like all requests to /foo/* to first be processed by a servlet.  
The servlet performs some operation (user authentication specifically).  
If the servlet processing performs normally, I want the request forwarded to
the page actually requested (in the case of .jsp files, the page must be
processed by the jsp engine first of course).

I've set my Tomcat 3.1 up as defined below.  The result is an infinite loop.
A request of /foo/junk.gif is redirected to the servlet and then to
/foo/junk.gif (which then is redirected to the servlet and then to
/foo/junk.gif... and so on).

Thanks so much for your help!

...Casey

---

Given a file at webapps/foo/junk.gif

And the following in server.xml : (Maps /foo urls to the middle_serv
context)


middle_serv


middleServlet




middle_serv


*.gif



And a servlet called middleServlet: 
public void doGet (HttpServletRequest request, HttpServletResponse
response) {
try {
// Perform user authentication.. on failure, go to
login page... otherwise proceed

// Determine the originally requested URL and
forward the user to that page
String orig_url = request.getRequestURI();

getServletConfig().getServletContext().getRequestDispatcher(orig_url).forwar
d(request, response);
} catch (Exception ex) {
ex.printStackTrace ();
}   
}

Re: j_security_check mapping

[Mike La Budde]

I ran in to the same problem. The solution is to modify the
mod_jk.conf-auto file (and save w/ a different name) as follows: 

#
# The following line mounts all JSP files and the /servlet/ uri to
tomcat
#
JkMount /iristafulfill/servlet/* ajp12
JkMount /iristafulfill/*.jsp ajp12
JkMount /iristafulfill/*.do ajp12
JkMount /iristafulfill/pages/security/j_security_check ajp12

Both of the last two lines were added manually. The first, 'cause
we're using struts and the second for the login page

Hmmm.  By default, the SSL connection factory in Tomcat is initialized to accept
all possible cipher suites.  It wouldn't be too hard to make that configurable.

In Tomcat 4.0, you have an additional option -- a recent addition to the servlet
2.3 spec requires the servlet container to expose two new request attributes:
the cipher suite that is being used, and the key size.  It would be possible to
programmatically reject such a request in a servlet or a filter.

Getting jsession param from URL

[Brian Hannan]

I write jsession into URLs I generate for web pages being served.  This
all works fine and Tomcat detects the session id in the URL.

The only problem is I would like to also grab the jsession ID from the
URL to detect URLs sent from pages related to a stale session.

I'm unable to see the jsession param.  I've tried playing with every
method in HttpServletRequest, but the jsession id is always missing.

Is there anyway to have Tomcat not strip jsession from a URL?

Thanks for the help.

This question came up earlier today as well.  The bottom line is that you cannot
do what you are after in Tomcat 3.x (which is based on the servlet 2.2
specification).  You can do it by using a Filter from the servlet 2.3 API (which
Tomcat 4.0 supports).  See my expanded explanation on a thread with subject "MVC

build failed on tomcat

Hi All,

I have installed j2sdk1_3_0 binary version on solaris 2.6
and had jakarta-ant built. When I tried to build the tomcat
it failed since there was no class of SAXParserFactory.
I could not find anything in the j2sdk1_3_0 directories.
Do I need to install other class libraries to make it work?

Why should they worry about compiling that for you?  I just installed 3.2 a

Solaris to get mod_jk.so to compile.  If you still can't get it to work
though, email me directly and I'll attach and send you a copy of my

You can ask Tomcat to give you the session id that was requested (whether it is
valid or not) by calling:

request.getRequestedSessionId();

There are other calls to tell you whether the requested session id was actually
valid, and whether it came from a cookie or the request URL.  See the servlet
API javadocs on HttpServletRequest for more info.

Init-Parameters in web.xml

[Thorsten Moeller]

Hi!

I use Visual Age for Java 3,02 with Tomcat 3.1 integrated. I have the
problem that when I start Servlets (e.g.
http://localhost:8080/servlet/my.package.MyServlet) the parameters
standing in "web.xml" are not read in. The file is stored in the directory
\webapps\ROOT\WEB INF. The web.xml should be error free,
since I exported the Servlet also into a new created context,
and it works reading the parameters in. Does someone have a tip?

Running JSP's w/ Apache and Tomcat

[Jeff Brown]

hi,

I would like to set up apache and tomcat so that apache handles all of my
static html pages and all of the JSP pages are handled by tomcat
basically exactly how JServ/GNUJSP works.  What do I need to add to
tomcat.conf/server.xml in order to get this scenario to work correctly?
I've been playing with different context settings and have checked all
available docs and faqs without any success.  With a default set up (simply
installing Tomcat, putting my jars in /lib and including tomcat.conf in
httpd.conf) when I try to access a jsp file that's in my
/usr/local/apache/htdocs dir, I get an error saying it can't be found in
webapps/ROOT.  Copying the file there seems to make it work, but then I have
to maintain the same file in two places because as soon as I remove it from
my apache document root, apache can no longer find the file and I don't even
get the Tomcat error.

Anyone out there with a similar scenario?  It seems like this should be
fairly basic, but the included documentation on Apache/Tomcat configs is
sketchy at best.

Hi All,

In order to install tomcat I upgraded our system to Java 2.
In both binary version of j2sdk and source version of it
I could not find the "classes.zip" (so that I could locate

jakarta-tomcat). Can anyone tell me what I am missing
here?

Between I could not find "SAXParserFactory" in jaxp.jar
and parser.jar from jaxp1-0-1.zip either. Any info or suggestion
would helpful. Thanks.

You are missing the Java API for XML Parsing.  When you unzipped the 
jakarta-tomcat, you should find a README file.  You'll have to read it's 
installation steps one by one.  It explains what else you have to install and 
how to setup all of the environment variables etc to make things work 
smoothly.  I'm a novice at Java stuff, but followed the README and it is 
working.  Now I just have to read LOTS more documentation to learn how to 
start making my own stuff.  I come from php/apache and postgresql, so this is 
much different!

Re: MVC problem

[Vik P. Solem]

Hello David.

I don't know if this will help you, but when we needed to perform some
basic functionality prior to each page request we created a super-class
for our servlets (actually it was jhtml, not JSP, but it was a while
ago).

This super class was a servlet that implemented the method
service(req,resp), and in that method we did some important global
things.  We tracked page level security, guaranteed a single thread per
session (by synchronizing on the session object), and then after/within
that logic we called super.service(req,resp) which then went on to run
the appropriate page for us.  (This requires that your JSPs (or servlets
if you write the controller separately as I'd suggest) extend this
intermediary class which would in turn extend HttpJspBase.

I'm not sure if I've explained it very well.  I'd be happy to write a
better description if you'd like one.  Please feel free to email me
directly at [EMAIL PROTECTED]

Assuming that I've described it well enough that it's recognizable, has
anyone else out there used this approach?

Tomcat 3.2 tries to read POST data before forwarding to JSP

[Duane Morse]

The following partial stack trace illustrates a problem/bug in Tomcat 3.2
(final release) when a servlet processes
a POST request and then forwards processing to a JSP.   In "pre-processing",
Tomcat is trying to read the form
data, but since it's already been read, it generates a "short read" error.
Since the servlet API
specifically says that the forward command allows one servlet to do some
processing of a message before
passing on the work to another servlet, this behavior is either a bug in the
Tomcat 3.2 implementation (trying
to read the POST data without knowing whether the subsequent servlet wants
the data) or it's a serious shortcoming
of the servlet API (you can't ever forward a POST request).

Postgres Driver.

[Sterling]

H-

Can anyone point me in the direction of a postgres driver so I can hook
up JSP to work with my postgres database?
I checked the Postgres website and it's down. 8^(

I'm getting
javax.servlet.ServletException: Unable to load class postgresql.Driver
errors when I attempt it.

I believe that's the problem.

Thanks for any information anyone can provide.
Thanks.

Re: MVC problem

[Vik P. Solem]

OOPS.

Sorry about that folks.  This won't work in Tomcat the way I described. 
I just noticed that in the Tomcat source the service method on
HttpJspBase is final.  

We're still waiting for management to decide on Apache-Tomcat vs.
WebLogic.  It looks like lessons learned previously in WebLogic are not
transferable to Tomcat.

Sorry about my previous noise on the list.  I guess all servlet
container are not created equal.  Time to reread that spec.

Re: j_security_check mapping

Mike,

I'm confused as to what you mean here?  First of all, what is that
"iristafulfill" context?  Is that you own?  I also
looked for a class file called "j_security_check.class" and I
didn't find it anywhere in the sample context or any other context that
comes with 3.2 final.

Can you or someone else be a bit more explicit as to how to get this to
work through Apache on port 80.

There are several prerequisites for building Tomcat from sources -- they are
documented (for Tomcat 4.0 at least) in the "README.txt" file in the top level
directory of the source distribution (CVS repository "jakarta-tomcat-4.0").

In particular, the error you got below is because you need to download and
install the Java API for XML Parsing (JAXP) release.  See the readme file for
more details.

Craig McClanahan

PS:  All of these steps are required only if you want to build Tomcat from
source.  If you just want to run it, download the binary distribution instead --
everything you need (except for a JDK, and the JSSE classes for SSL) is
included.

Re: build failed on tomcat

[Scott Liu]

Now it is being built after I modified the "build.sh" and
"build.xml" to reflect the change of "xml.jar" in
jakarta-ant.

RE: build failed on tomcat

[Renee Petris]

You' need to install an XML parser that is compatible with the Java
  API for XML Parsing (JAXP) specification.  Try Sun's reference
implementation
at: http://java.sun.com/xml. You'll need to add jaxp.jar and parser.jar to
your classpath.

Re: MVC problem

[Vik P. Solem]

OK, this works (tested in Tomcat 3.1).

Extend HttpServlet and implement HttpJspPage. (The easy way is to copy
HttpJspBase.java and then edit the service() method.)

Then have your JSP's (or your servlets I think, but I haven't tested
that yet) extend the new class that you just created.

In the service method you can do any pre processing that you like before
ever getting to the JSP page itself.  This allows you to write a bit of
code once and have it run in front of every page that you want.

I have a dumb example of this for Tomcat 3.1.  For the curious, please
send me email directly, as I'm a bit uncomfortable at the current length
of this thread.

This is not actually a connection pool.  It is configuring which JDBC driver
will be used by the JDBCRealm module to look up users for container-managed
security.  You can certainly use SQLServer for this as long as you have a JDBC
driver that supports it -- the details for how to configure the parameters for
this driver should be in the driver's documentation.

The basic entry in server.xml would look similar to the others -- you would
replace the class name with the class name of the driver you want to use, modify
the username and password parameters, and then set up the connection url however
the driver's documentation tells you to.

As I mentioned on the same thread "MVC problem" (after I had a few false

Import statements in JSP generated servlets

[Elijah Roberts]

I have a question regarding the import statements that get inserted into
the servlet code generated from JSP files. Specifically with Tomcat 4,
but it is really just a general JSP question. At the top of each
generated servlet file, Tomcat inserts serveral import statements, such
as:

import java.io.PrintWriter;
import java.io.IOException;
...

In a JSP page that I wrote, I used a PrintWriter object, but forgot to
import it myself in the JSP file. On my test Tomcat box it compiled and
worked properly, because of the import statement that was inserted by
Tomcat when generating the page. When I went to actually deploy it to our
production box, which runs JRun, it would not compile without my adding
an import statement to the top of the JSP.

My question is, what does the JSP spec say about this? The goal for JSP
is to get it to run without modification on any server that supports JSP,
so which behavior is correct? Should Tomcat not import any packages or
objects outside of the javax.servlet package, or is there a set of
packages and classes that should be imported by all JSP compliant
servers? I'm going to go look through the spec, but I thought I'd ask as
someone here probably knows the answer.

Don't try to mix jaxp-1.1ea with Tomcat!

[Duane Morse]

I've tried for 3 days to get Tomcat 3.2 (b8 and now the final release0
to work with Sun's 1.1 early release of XML parsing software (jaxp-1.1ea),
without success,
so if you're looking for XML parsers to use with your Tomcat build, don't
use these!

custom tag life cycle question - are custom tags expensive?

[Dave Harms]

I notice that section 5.4.7 of the JSP 1.1 spec states that "at 
execution time the implementation of a JSP will use an available Tag 
instance with the appropriate prefix and name that is not being used, 
initialize it, and then follow the protocol described below. 
Afterwards, it will release the instance and make it available for 
further use."

When I look at my generated JSP code I see new instances of my custom 
tags created on each call to _jspService. This seems to be in 
contravention of the spec which implies a tag instance pool. It would 
also suggest that some care needs to be taken to make custom tags as 
lightweight as possible in the current implementation. 

Thoughts?

Re: j_security_check mapping

[Mike La Budde]

Yes, sorry for the incomplete explanation, iristafulfill is the name of
the project/context that I'm working on. 

In order to integrate the Apache web server w/ Tomcat you need to tell
Apache which "things" to redirect to Tomcat. That is the whole
point of the 

JkMount xyz worker 

lines in your mod_jk.conf-auto file (I have made modifications to mine
and saved it as mod_jk.config)

The login.jsp form that you use must be coded in a specific way (i.e. the
field names, and the POST to action="j_security_check") The
latter, j_security_check, is handled by the AccessInterceptor (a request
interceptor specified in your server.xml file and available in your
distrib. under src/org/apache/tomcat/request/AccessInterceptor.java).
This is why the value "j_security_check" is not a class file.


I hope I've clarified things a bit, please re-read the mod_jk How To for
a much better explanation than I've given here. 

Mike

Mike,

I'm confused as to what you mean here?  First of all, what is that
"iristafulfill" context?  Is that you own?  I also
looked for a class file called "j_security_check.class" and I
didn't find it anywhere in the sample context or any other context that
comes with 3.2 final.

Can you or someone else be a bit more explicit as to how to get this to
work through Apache on port 80.

JkMount /iristafulfill/servlet/* ajp12

Both of the last two lines were added manually. The first, 'cause

I am using Tomcat 3.2b6 with mod_jk. When accessing
http://localhost:8080/examples/jsp/security/protected/index.jsp
The login.jsp page works (posts) fine. However, when
accessing through Apache,
http://localhost/examples/jsp/security/protected/index.jsp,
the login.jsp comes up but j_security_check is not
found when I post. Has anyone else had this problem?
Can I manually do the mapping from within web.xml?

Tomcat 3.2 ClassCastException after servlet update on getAttribute

[David Rees]

I also just tried this on Tomcat 3.2, same problem.

Again, here's the problem:

I have a form which posts to a jsp, which then instantiates a bean with the
data from the form, which then forwards the request to a servlet which does
a getAttribute to obtain then the bean data.  It then forwards on again to
another jsp.

The problem occurs during development:  Updating the servlet causes a
ClassCastException.  Shutting down and restarting Tomcat makes the
ClassCastException go away.

This happens on Tomcat 3.1 and 3.2.  It does not happen on the Tomcat 4.0 m4
build.

Should I post this issue to the -dev list?  It seems like a Tomcat bug to
me.

formbased security

[John de la Garza]

where can I get complete documentation on formbased security?  The servlet

The default import list is defined in the JSP spec.  For JSP 1.2, it's on p. 47:

java.lang.*
javax.servlet.*
javax.servlet.jsp.*
javax.servlet.http.*

In Tomcat 3.x, a known problem with Jasper was that it generated some additional
non-standard import statements.  It looks like we haven't addressed that problem
yet in Tomcat 4.

Re: Postgres Driver.

[Sterling]

H-

Thanks for the reply.

I ftp'd into posrgresql.org but didn't find any src directory. 8^(

Are you saying that you went into this directory and downloaded a file that you
compiled on your system (using root) and it than was able to be called via JSP?
Or was there some other setup and README.txt file that came with it that you
had to use to set it up?

Any other thoughts on where I could find this file in some other location? How
big is this file? KB's or MB's? What's the name of the file? Do you know the
name?
I went to the website and found some ftp directories but nothing that looked
like what I was looking for. I did find a 'source' directory but it didn't have
an interfaces directory. 8^(

I'm using 6.5.3 postgres. Would it be easier to just dl the lastest and
greatest and install that? Would that be a valuable solution? Or would I still
need to locate this extra file and get it somewhere?

Thanks again for any further info.

RE: Servlet in the middle... in the middle.. in the middle

Neat solution!  Thanks Vik.

One snafu though this only protects JSPs...  I also need to protect html
and gif files.

Thanks again...

As I mentioned on the same thread "MVC problem" (after I had a few false
starts...) you can do your authentication in a single servlet and then
use <%@ page extend="MySecureServlet"%> in your pages so that they all
extend your servlet with the desired functionality.

web app. mapping configuration

[Stefan Woithe]

Hi all,

Using Tomcat 3.2final

In $TOMCAT_HOME/conf/server.xml:

 


In myapp/WEB-INF/web.xml:



MasterServlet


com.hulla.devil.MasterServlet




MasterServlet


/



So I can call

http://localhost:8080/myapp

an it works fine. Now, the servlet includes JSP which contain image tags. The images 
are localted in

myapps/images

and the "src" attribute of the "img" tag reads like:

src="images/myimage1.gif"

The browser asks correctly for

http://localhost:8080/myapp/images/myimage1.gif

PROBLEM: The server doesn't deliver them. Instead it calls the MasterServlet. How to 
write web.xml or organize the myapp subdirectories to enable the pictures to be found? 
One thing is 'must be': The MasterServlet acts like an welcome page (so I never want 
to call something like

http://localhost:8080/myapp/MasterServlet

)

Thank you indeed

Stefan

Re: Postgres Driver.

[Sterling]

H-

Thanks for your email.

I found another page that has the download file but not for my version.

I'm using postgres 6.5.3.
Here's the page in case others are looking for it.
http://www.retep.org.uk/postgres/download.html

The closest version I found on this page is 6.5.2. Would it be a problem to use
this version instead?
I really don't know.
