I have never seen JSPC cut off a jsp file but if all the html in your jsp is
not getting to the browser that sounds like you need to check your buffer
size. just a thought :)

Hi,
Is there any file size limit for jsp files in Tomcat,
I am using JRE 1.3.01 and Tomcat 4.0.2 ,
and Tomcat does not produce jsp files more then 35 kb,
I checked and i saw that it produce ".java" files true but 
somehow it does not send all html codes to client.
sincerely,
Ugur

RE: org.apache.catalina.logger.SystemOutLogger

[NIVET Rémi]

Hi all

I think I've got the answer to your question.

The fact is that you've got three different loggers : FileLogger,
SystemErrLogger and SystemOutLogger. If you read carefully the doc,
you'll see that you can't specify any file name for the Systeme's
loggers. So if you specify a FileLogger for a , all logs will be
redirected to the file you defined for this logger but if you specify a
SystemLogger all logs will be redirected to the standard error/out
stream.

Hope this help,

Rémi.

RE: Tomcat x Apache

[Ion Larrañaga]

Sorry for my mistake. You are right that Apache should redirect the request
to Tomcat directly. This means I should read messages more carefully ;)

Are you able to access static pages with Apache? Do you have an index.html
in "/home/myDocs" to test if you can access http://your.server/index.html ?

I think that maybe Apache is denying you access before sending the request
to
mod_webapp. This may be if you have only changed your DocumentRoot directive
without granting access to it. Have you changed the  where it
says
"This should be changed to whatever you set DocumentRoot to" ?

Hope it helps,

   Ion

My  webapps directory and all its directories are read and execute free for

Any way, I think Apache should pass all the /examples requests to
Tomcat and not trying to read the directly from the file system.

It looks more that Apache is not allowed to connect to Tomcat. I´ve
already check all the possibilities but could not find any parameter(s) in
httpd.conf or server.xml that could prevent the connection.

Any other clue?

Thank you.

My  WEB-INF folder appears to be in capital letters... I don't understand why I get 
the NoClassDefFoundError.
To be sure I tried this jsp code :
<%
 String classpath = (String)context.getAttribute("org.apache.catalina.jsp_classpath");
 StringTokenizer st = new StringTokenizer(classpath, ";");
 while (st.hasMoreTokens()) {
  String curr = st.nextToken();
 %>
    <%=curr%>
 <%
 }
 %>

I got the correct result for the classpath constructed by tomcat :
  E:/Webapps/Context/WEB-INF/classes
  E:/Webapps/Context/WEB-INF/lib/classes12.jar
  E:/Webapps/Context/WEB-INF/lib/myjarfile.jar
  E:/Webapps/Context/WEB-INF/lib/oraclexsql.jar
  E:/Webapps/Context/WEB-INF/lib/xmlparserv2.jar
  E:/Webapps/Context/WEB-INF/lib/xsu12.jar
  D:/Apache/jakarta-tomcat-4.0.2/classes/
  D:/Apache/jakarta-tomcat-4.0.2/lib/jasper-compiler.jar
  D:/Apache/jakarta-tomcat-4.0.2/lib/jasper-runtime.jar
  D:/Apache/jakarta-tomcat-4.0.2/lib/naming-factory.jar
  D:/Apache/jakarta-tomcat-4.0.2/common/classes/
  D:/Apache/jakarta-tomcat-4.0.2/common/lib/naming-common.jar

  D:/Apache/jakarta-tomcat-4.0.2/common/lib/servlet.jar
  D:/Apache/jakarta-tomcat-4.0.2/common/lib/tools.jar

So : the tomcat classpath looks ok, but I still get the NoClassDefFoundError when 
trying to access my classes... any clue ?

Hi,

I think you have to change 

WebAppConnection Tomcat_Apache warp localhost:8008

to

WebAppConnection Tomcat_Apache warp myServer:8008

and


to

.

I don't know if both is neccesary. But try it.

Can't help here, sorry. You should consult with Apache docs. And you have

It looks like you don't have JSSE installed in proper location.
It resides in $JAVA_HOME/jre/lib/ext in my case and
I believe it can live in $CATALINA_HOME/server/lib
or in $CATALINA_HOME/common/lib if your apps use it.

It looks like problem with your catalina.bat. It got corrupted somehow.
that "-Djava.endorsed.dirs=. " happened to be on a new line.
You can comment out "@echo off" there and, assuming your JAVA_HOME 
is set correctly, try "catalina start".
Hope it helps.

With Tomcat 3.2, you can specify additional contexts in the file

conf/server.xml

and the contexts can be anywhere on your server, at minimum. I am doing
this, TC 3.2 (and 3.3) on D: and the directory structure for some more
webapps on E:.

With Tomcat 3.3, there is the additional method of specifying contexts in
files named like

conf/apps-appname.xml

where for a webapp called appname. The apps-examples.xml in the /conf
directory is one of several provided in the distribution. I am not using v.
4, so I don't know, but I have the impression that it is using the method
provided in 3.2? It's in the on-line docs under "deployment organization" or
something similar.

RTWM:
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/deployment.html
http://jakarta.apache.org/tomcat/tomcat-3.3-doc/appdev/deployment.html
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/appdev/deployment.html

The path attribute of the context tag specifies the selector portion of the
URI to plug into the browser, and the docBase attribute specifies the
location in the local file system. Thus,

The best you can do is to relax :)
I don't think it'll be kind of optimization to reduce number of threads.
but of course it depends on
- how much TC instances are running
- how much connectors they're using
- how much applications are there
- how much threads are created by those applications
and so on.

Ämne: RE: Tomcat x Apache
Sorry for my mistake. You are right that Apache should redirect the
request
to Tomcat directly. This means I should read messages more carefully
;)
Are you able to access static pages with Apache? Do you have an index.html
in "/home/myDocs" to test if you can access http://your.server/index.html
?
I think that maybe Apache is denying you access before sending the request
to
mod_webapp. This may be if you have only changed your DocumentRoot
directive
without granting access to it. Have you changed the 
where it
says
"This should be changed to whatever you set DocumentRoot to" ?
Hope it helps,

Asunto: Re: Tomcat x Apache
My  webapps directory and all its directories are read and execute
free for
all users. So I don´t think this is the problem.
Any way, I think Apache should pass all the /examples requests to
Tomcat and not trying to read the directly from the file system.
It looks more that Apache is not allowed to connect to Tomcat. I´ve
already check all the possibilities but could not find any parameter(s)
in
httpd.conf or server.xml that could prevent the connection.
Any other clue?
Thank you.

are you using mod_webapp?  I find this to be a problem when using apache and

sometimes some images gets loaded and sometimes some others...

The path of  the image is not a problem, bcos if it was, i should be
consistently get the problem for the same image, which is not happening.

I had the same problem.  What is was, was that the URI I was using for the
imgaes was

/images/myimage.gif

Which when used via Apache/mod_jk were being request from Apache's doument
root.

Changing the URI to...

images/myimage.gif  (no initial slash)

Fixed the problem

RE: JSP programming under Tomcat 4.0.2

[Randy Layman]

All versions of Tomcat (and all JSP containers for that matter)
require you to add <%@ page import=""%> to your JSP files.

Also, Tomcat versions 3.3 and beyond ignore your system's classpath
variable - it causes to may problems with people not understanding how this
interacted with the web apps.

Lastly, lots of people have experience using JSP with Tomcat 4.02.
If you have more specific questions please ask - this is the right forum.

RE: [TC402] Manager Context in IIS 5 is access denied

[Randy Layman]

Check the permissions for the redirector dll and the virtual
directory.  Also, if you want Tomcat to handle authentication (which you
need for the manager app), IIS must be configured to allow anonymous access
to the virtual directory.

How can I achieve that a servlet Serv123.class

http://somehost/servlet/Serv123

is able to be called
http://somehost/myfolder/Serv123
and located in the directory

Why "localhost:8080" NOT expanded to "http://localhost:8080"

After having started Tomcat 4.0.2 I entered
the URL 
localhost:8080 
into my browsers URL entryfield.
Surprisingly it is not automatically expanded to
http://localhost:8080
but gave an error (page not found)

With other URLs in the outside internet world(when I am connected through my providers 
connection) it works fine.

Which option do I have to change to get an auto-complete?

You can set up aliases for servlets in the web.xml but the servlets still
have to reside in the WEB-INF directory. Have a look at the documentation

Most browsers will only do the autocompletion with addresses starting
'www', I doubt there's any way you can change this. You could just
create a bookmark to your server if it's bugging you...

ehance my skills as they say "the more you do the more you can !!"

RE: Why "localhost:8080" NOT expanded to "http://localhost:8080"

[Randy Layman]

ICANN assigned HTTP traffic (that for the web) to port 80.
Consequently, web browsers assume that web traffic will occur over port 80.
They also handle other protocols (like FTP on 21).  Since 8080 is no an
assigned number for a protocol the web browser doesn't know how to talk to
the other end.  Therefore you have to tell it what protocol to use (HTTP).

RE: IlligalStateException -- getOutputStream() has already been called for this response.

[Nicolas Silberzahn]

Bonjour,

getOutputStream()  can be done only once.
I guess the first servlet you are invoking is doing it.
Then you forward to a jsp which try to do it again

If it forwards to a jsp, the initial servelt don't have to send something on
the stream, thus don't have to call getOutputStream() .

Bonne journée,

RE: Unable to compile class for JSP

[Nicolas Silberzahn]

I Get the same problem. The above import fixed the problem.
This as not mandatory with TC3? It worked fine without the import...

RE: IlligalStateException -- getOutputStream() has already been called for this response.

[Nicolas Silberzahn]

Bonjour,

getOutputStream()  can be done only once.
I guess the first servlet you are invoking is doing it.
Then you forward to a jsp which try to do it again

If it forwards to a jsp, the initial servelt don't have to send something on
the stream, thus don't have to call getOutputStream() .

Bonne journée,

RE: Why "localhost:8080" NOT expanded to "http://localhost:8080"

[Chris Campbell]

This is not surprising really. In most URI addresses the protocol (http, ftp
etc) is the part before the colon. If you leave 'http:' out of a URI with a
colon in it, the part before the colon becomes the protocol, in this case
'localhost'.

Reload Context Problem-Tomcat 4.0.1

[Haris Papadopoulos]

Hi,
When classes or servlets are updated, the context is being reloaded. However, we use a 
pool of connections to Firebird in a development environment and it seems that 
sometimes (not always and this is strange), the context is reloaded but the new pool 
of connections is never created. As I said, sometimes it works fine and sometimes 
doesn't. The connections are made via inetd to a Classic Server Installation of 
Firebird on Linux. I don't know if it's an Interserver issue but we didn't have these 
problems in the past using Resin. 
Thanx in advance.

RE: Why "localhost:8080" NOT expanded to "http://localhost:8080"

[Randy Layman]

Not quite - A fully qualified URL is formatted like:
procotol://hostname:port/path
The hostname is immediately follows // and is terminated by the next
element.  This allows the : to unambiguous, even if the optional elements
are left out.

Use Netscape or Opera. They seem to try HTTP by default.

Your log looks like you already use mod_jk.

Scope / Instantiation of JSP pages / declarations

[Thorsten Barth]

Hello,

Using Tomcat, I found out that JSP pages are instantiated only once - the 
first time they are requested. The values of the local declared variables 
are kept for subsequent requests and even shared between different sessions.

If two requests are accessing the same page at the same time, this messes 
all up, so I would like to change this behaviour. I searched Suns JSP specs 
and the tomcat documentation, but I just found an attribute in the page 
directive that forces serialization of the requests (threadsafe="false") - 
but I think that would significantly reduce performance...

Do you know
- if and why the current behaviour of tomcat is intended?
- where I can search for more info?
- if there is an option that tells Tomcat to create a new instance of JSP 
pages every time they are called

P.S: Allaire JRUN seems to behave different 

Thanks and bye...

Yes it would.

Yes - it keeps memory consumption down (instead of having thousands of
instances of the JSP class for thousands or requests, you have only one)

The JSP Spec and Servlet Spec would probably be good resources

I don't believe so

If so then it doesn't comply with the JSP spec.


One thing to remember is that only variables declared in the <%! ...
%> blocks and page scoped beans are shared between requests.  If you want
variables that are used only in the scope of one request then either use <%
... %> blocks or set your bean scope to request.

Threading my app

[Dominic Clay]

Hi,

Have been successfully writing small webapps for some time, but I have hit a
difficult issue and was wondering if anyone had any ideas

the scenario...

Page1 contains a link to a document.
when the link is clicked, Page2 appears which contains a large text document
stored is a text field in a DB.  This field can be anything from 100K to
several MB.

This is an acceptable size for our network.  However before showing the page
the JSP page runs through a routine to look for certain words and prefix
them with a link to the previous word, *and* postfix them with a link to the
next word.

There can be up to 100 of these words in a document.

The issue is this can take up to 200 seconds to complete.

The Idea...

I want to put this processing in a separate thread which is called when
Page1 appears.

This jsp page starts the processing.
Page2 then requests the data (possibly from a session variable) returned by
this thread and displays the data...

So for a thread newbie...

Is this possible, if so, how.


Thanks,

Dominic

configuring additional servlet path

[Uri Shohet]

Hi List,


I went through all (IMHO) tomcat documentation and haven't found a solution.

In Apache JServ I could make 2 servlet zones and map them as follows:

http://myhost/myproduct/servlet -> /myproduct/run/servlet
http://myhost/myproduct/pubservlet  -> /myproduct/run/pubservlet

I need this because I want /myproduct/servlet/ servlets to be protected by 
username and password, and /myproduct/pubservlet to be unprotected (public - 
hence the name).

Now, in tomcat I've set up a Context /myproduct in server.xml


  


and moved all the files and dirs from /myproduct/run/servlet to 
/myproduct/run/web/WEB-INF/classes and all the servlets such as 
http://myhost/myproduct/servlet/Snoop are working fine.

My question is how can I set up /myproduct/pubservlet mapping so that when 
client calls http://myhost/myproduct/pubservlet/mypackage.MyServlet, tomcat 
will call /myproduct/run/pubservlet/mypackage/MyServlet.class 

Any help appreciated

Thanks in advance

LoadModule webapp_module modules/mod_webapp.so
AddModule mod_webapp.c

when i try http://localhost/examples/, it correctly gives me a directory

You mentioned you installed Tomcat from the RPM?  If so, I think you may
need to use port 8180, not 8080 - check the archives.  Based on the
"Starting services..." messages above, I think Tomcat is running OK.  I'm
not a *nix person - is there a handy command to list activity on all ports
that you could run?  Check if there's an unusual port active in the 8000's
range.

Re: tomcat waiting in linux

[rsequeira]

If you are running tomcat straight out of the box, then the log messages
seem correct. By default the http connector listens on port 8080 unless you
modified the server.xml and changed the port (see  in
server.xml).
Trying telnet-ing to the port 8080 once you have started. See what ports
are open by typing "netstat -n".

Subject:  tomcat waiting in linux

I am running
  Java 1.4 from sun for linux
 RedHat 7.2
 and TomCat 4.0.2 from the rpm file

I get the following message on my screen
Using CATALINA_BASE:   /var/tomcat4
Using CATALINA_HOME:   /var/tomcat4
Using CATALINA_TMPDIR: /var/tomcat4/temp
Using JAVA_HOME:   /usr/java/j2sdk1.4.0
Starting service Tomcat-Standalone
Apache Tomcat/4.0.2
Starting service Tomcat-Apache
Apache Tomcat/4.0.2


which looks wrong since I am trying to run it just Standalone.  Does it
come pre configured to run with apache?

I load up Konqueror and goto http://localhost:8080/ and
http://127.0.0.1:8080/ which comes back with "cannot connect to localhost
port 8080".  Tomcat should work fine with the above verisons right?

Thanks,
Robert

RE: tomcat waiting in linux

[Thutika, Swamy]

 I used to get the same display when i run the tomcat33a / tomact402. I
removed the
 Apache service set up from server.xml. Everything works fine even after
that.
 My feeling is that the examples erver.xml has this server predfeined within
it.

 HTH,

That looks OK to my newbie-ish eyes.  Put another way, that's what I get on
a Windows box, and my setup works OK.

I'll defer answering that to someone who knows what they're talking about ;)
but like I say, I get the "Starting servive Tomcat-Apache" lines on my
console at startup.

RE: IlligalStateException -- getOutputStream() has already been called for this response.

[Nicolas Silberzahn]

Bonjour,

getOutputStream()  can be done only once.
I guess the first servlet you are invoking is doing it.
Then you forward to a jsp which try to do it again

If it forwards to a jsp, the initial servelt don't have to send something on
the stream, thus don't have to call getOutputStream() .

Bonne journée,


Nicolas Silber*zahn

Depends on the application/library that is using the file and how much

I thought that the problem was, how to handle the change not
how to recognize it.

If the xsl is just file and you know where it is, 
what about this:

long mLastLoad = 0;
File mXSLFile = new File();
if (mXSLFile.lastModified() > mLastLoad) {
  doWhatEverToReRead();
  mLastLoad = (new Date()).getTime();
}

P.S.:

I still beg that the real problem lies in doWhatEverToReRead()

I suspect you're right - my attitude (as a newbie grateful just to get it
working) has tended to be: if it works, don't try and fix it!  I should
probably try pruning my server.xml file...

AW: XSL - Reload a resource without restarting

[Lauer, Oliver]

I haven't spend much time on this request yet but what I know is that a
webapp has to parse a XML stream with XSLT and the XSL is subject to change.

And I don't want to reload the webapp for that purpose. 

Background: The XSLT filters our XML stream. 

Any suggestions ?

Got some questions about load balancing in 3.3a

[Michael Molloy]

I've got some questions about load balancing with Tomcat 3.3a.

First of all, the Tomcat-Workers-How-To that comes with 3.3a says that the 
workers.properties file contains working entries for an Ajp12, Ajp13, and a load 
balancing worker. However, it also says that the tomcat workers to be used for load 
balancing should not appear in the worker.list property, but they do in the default 
workers.properties file. Should they or should they not be in that list? 

Also, if I want to load balance using a remote machine, what configuration changes 
need to be made to the tomcat config files on that remote machine? Is it as simple as 
changing the remote worker port to match the port on the host machine? For example, 

Computer host workers.properties excerpt:
worker.test.port=10001
worker.test.host=192.168.0.43
worker.test.type=ajp13

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp12, ajp13, test

Computer remote (192.168.0.43) workers.properties excerpt
worker.test.port=10001
worker.test.host=localhost
worker.test.type=ajp13

I'm really confused at this point. I tried this the other day and couldn't get the 
host machine to communicate with the remote machine. Can someone offer some insight?

Thanks

Re: XSL - Reload a resource without restarting

[jeff . guttadauro]

Hi, Oliver.

   I can offer an idea (doubt it would qualify as brilliant though - sorry).
If you do a getResource from the ServletContext, it will give you a
java.net.URL.  Then, maybe you could do an openConnection on the URL to get a
URLConnection.  Then, try the getLastModified method on that...  Don't know if
this will work, but figured I'd throw it out there as a suggestion.

Re: JSP programming under Tomcat 4.0.2

[Ming]

Hi, Randy,

Thanks a lot for your information.

Here is my situation:

My older tomcat is version 3.3 and new tomcat is version 4.0.2.

This is the script in the older tomcat directory(very simple one):

<%@ page language="java" contentType="text/html" %>
<%@ page info="Simple testing program" %>
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.net.URL" %>

<%@ include file="includes/js_include.txt" %>




<%  String inputString = "passwd";
jcrypt jcrypt = new jcrypt();
String cryptedPassword = jcrypt.crypt("MM", inputString);

%>

Simple testing program

<%= inputString %> and <%= cryptedPassword %>




But under the new version of tomcat, this won't work until I put a line <%@
page import="jcrypt" %>at the beginning. I've put my jcrypt.class file in
WEB-INF/classes and under $CATALINA_HOME/classes as well and restart the
tomcat and apache. Still seems not working.

I just read the documentation from jakarta site and you are right, tomcat 3.3
and above version ignore the CLASSPATH variable. But my question is, my older
version tomcat is 3.3 and new one is 4.0.2. Why does this script work under
the older one and not the new one?

Thanks a lot for your help.

virtual hosts/certificates

[Bernhard Wraase]

Hello,

is it possible to use several certificates in one tomcat?
I would like to configure a different cert for each virtual host.
I.e.:
cert A for virtual host 1
cert B for virtual host 2
cert C for virtual host 3
As far as I understand the docs it is not possible.

Does anybody know a trick?

Upload bug ...

[Julien OIX]

hi everyone, 

I'm using these RPM's on a Linux RedHat 7.1

apache-1.3.22-1.7.1 (with mod_throttle-3.1.2-3 mod_put-1.3-2
mod_bandwidth-2.0.3-2)

tomcat4-4.0.1-1

mod_webapp-1.0.2-1

and it seems there's a bug whit file upload ...

Is this possible at this time to recompile a "clean" mod_webapp.so ,
and if not, does use of mod_jk.so permit file upload, and which RPM or
source to take for ?

Thanks in advance ...

"Java and XSLT" (Eric Burke / O'Reilly) shows a generic approach (additionally 
using Templates) for this. you could download the examples and have a look a

Troubles with the list: 

Tomcat (4.0.2) expiring protected forms

[Towns, Peter (ANTS)]

Hi all,

I'd like to stop Tomcat (4.0.2) from expiring my forms and causing my
browser to spew out "Your webpage has expired, etc..." whenever a user
history.back()s to the form. Tomcat seems to be pretty keen to do this since
it's trying a whole bunch of headers to expire/no-cache my pages.

I've googled around it it's been suggested that this happens because I've
slapped a security-constraint across the whole site. So, Tomcat expires
every page in order that other users can't history.back() to any
(potentially sensitive) forms ..?

But is there so way to toggle this behaviour in Tomcat's config ..?
Obviously I'd rather not have to hack up any HttpServletResponses to achieve
this...

Any suggestions would be appreciated (& I apologise if I've missed something
obvious...),

Pete

invalid https url generates NullPointerException

[Steve A Drake]

 Hello. I just downloaded and installed Tomcat 4.0.2 and jsse1.0.2 on my
RH 7.2 box. I configured SSL under Tomcat so that the test URLs:
http://localhost:8080/ and https://localhost:8443/ work fine.

 The problem that I am having is that, if I accidentally enter:
https://localhost:8080/ Tomcat bogs down and throws the following
NullPointerException in catalina.out. I know that this address is invalid
but I'm surprised to see this behavior. Did I miss some configuration detail?
TIA for your advice.

RE: invalid https url generates NullPointerException

[KC Berg]

did you check your redirectPort in server.xml? 

--


--

What I did to enforce the use of https and eliminate your issue was the
following...


if(request.getServerPort() != 443){
  response.sendRedirect("https://"; + request.getServerName() +
request.getServletPath()+"?"+ request.getQueryString());

}
---

The above code works if you setup tomcat to use the standard ports for http
and https. However you can use the above code in the following manner if you
need to use the default tomcat ports.



if(request.getScheme().equals("http")){
  response.sendRedirect("https://"; + request.getServerName() + ":8443" +
request.getServletPath()+"?"+ request.getQueryString());

}




I'm not sure if this is what you were after but it should work :)

RE: JSP programming under Tomcat 4.0.2

[Randy Layman]

I believe that this is one of the ambiguities of the JSP/Servlet
spec.  You old version will only work on Tomcat 3.3, not TC 3.2 or the newer
4.0, and it will only work if the JSP file is in the root directory of your
webapp.  The reason is how the .java files are generated.  

Under Tomcat 3.3 the package is set to be the path within the web
app.  The root directory is in the unnamed package and JSP files in an
sample1 directory are in the sample1 package.  Since Java implicitly imports
all classes in the same package, jcrypt, which is also in the unnamed
package, is found under this scheme.

Under other versions of Tomcat the package has other text preprended
to the directory to make the package name (I believe one of them uses
org.apache.jsp, but I'm not absolutely sure about that).  In this case only
other JSP files in the same directory are implicitly imported and jcrypt
isn't.

I don't believe that the spec specifies a requirement on this (I'm
sure Craig will correct me if I'm wrong), which leads to the portable JSP
developers rule - Import all classes needed!

[Dim Question] Redirecting GET http://blah.com/ resource -> GET /resource - Tomcat 4

[CAM]

Hello all,

I'm sure I'm missing something very basic here but I can't think what. I'm using 
a little proxy (HttpSniffer) to debug header and cookie info between my browser 
and a remote Tomcat 4-b6. I'm getting failures to requests (404's) when I go 
thru the proxy and I can see in my access logs that this is because the requests 
are arriving as:

192.x.x.x - - [28/Feb/2002:17:30:49 00] "GET 
http://my.host.com:8080/dms/servlet/dms HTTP/1.0" 404 263

instead of:

192.x.x.x - - [28/Feb/2002:17:24:16 00] "GET /dms/servlet/dms HTTP/1.1" 200 2294

Rather than rewrite httpsniffer, I suspect I need some form of redirect - 
besides, the sniffer works with other sites (e.g. Google). I haven't managed to 
dig out anything about redirection from the docs - there are a lot of facets to 
the information. Is redirection associated with the Engine? The connector?

So, an RTFM is probably deserved but a clue as to where would be tremendous.

It does that to avoid caching by intermediate proxies (using back is not the

Reloading of beans and sessiopn no longer valid

[Jason Webber]

When I update a bean in my webpages that handles reports, everything seems
to reload.  The database bean reloads that has nothing to do with the report
bean.  This causes my database connections to be reestablished.  The scope
of the database bean is application.  Also all valid sessions are now gone
and all the users must relogin in.  How can I make it so that only the class
that has changed reloads or classes that depends on that class, but not
everything else?

Thanks

Re: JSP programming under Tomcat 4.0.2

[Ming]

Hi, Randy,

Thanks a lot for your reply. I think you raised a very good question regarding
portable JSP development. Everytime when  I try to move the JSP codes from one
place to another, I spent so much time on just making them work again.

I'm very slow on this. So, is that possible for you to explain to me what
should be the right way to develop a set of portable JSP codes?

This is what I'm currently doing:

1. I make a directory under webapps, call it xml.
2. Under xml, I have the following directories:
WEB-INF (with  classes, jsp, lib web.xml),
images (contains all my images)
search.jsp  ( the main JSP script used for searching and some other jsp
scripts)
includes   ( contains all my includes files, including .txt file, .jsp file
which will be used in the main search.jsp and other jsp files)
servlets
3. And I put all my class files and jar files under WEB-INF/classes and
WEB-INF/lib directories in the xml directory.

4. And I have a source directory in $HOME/local/src/ and put all my java source
files there.

I'm a beginner for JSP programming (and JAVA programming) and would like to
start the right way. Can you give me some suggestions on this?

Thanks a lot and really appreciate your help.

Ming

Custom error 401 page?

[Robert Wille]

If I define a custom error 401 page, I get an error 500 when I attempt to access a 
protected resource (protected with BASIC authentication). There is a 
NullPointerException thrown somewhere deep in the bowels of Tomcat. I would really 
like to display my own page when the user fails to authenticate, rather than 
displaying the default page. Is it possible to do this? I am using Tomcat 4.0.2.

RE: JSP programming under Tomcat 4.0.2

[Randy Layman]

I would suggest looking at the Servlet spec, chapter 9 covers the
Web Application and sections 9.4, 9.5, and 9.7.1 seems especially relevant
to your question.

I didn't see the original post, but just Craig's answer.
I'm not sure exactly what you want, but I did something
similar that required NO modification of the tomcat
mechanisms.

My goal was to allow users to log in with domain\userid
to the same application (and use the domain to
show them different data)
and allow each domain to have its own set of users
(e.g. same userid) and be managed independently.

I did this with only a couple of minor modifications:

My login.jsp collects domain, userid and password.
It uses a simple JavaScript one-liner to concatenate
domain\userid to create j_username
(I use a '\', but you can use any separator
char you want (don't use ':' since HTTP uses that as the 
userid:password separator.).

If you want to use BASIC authentication to do this
you just need to enter domain\userid as the 
userid.

In the database I use the domain\userid as the 'userid'
that I tell Tomcat about in the Realm statement
(actually I use an Oracle view to concat the two
fields, but that isn't important).

This creates multiple user 'domains' very simply
but does require the user to enter a domain name
in addition to userid and password.

Database bean Destroy

[Jason Webber]

I have a database pooling bean that I use.  Is there a way to tell when the
bean is being destroyed becuase the bean has been replaced with a newer
version or is being unloaded for some reason?  I need to know so that I can
close the database connections that the bean is controlling.  I dont want to
wait for the connections just to timeout and have the database reclaim the
connection sessions.  This is because I sometimes get maximum sessions
exceeded with my oracle database.

TIA

Problem with ISAPI redirector for Tomcat 4.0.2

[Bryan Baker]

Hello,

I added the ISAPI redirector for 4.0.2 (isapi_redirector.dll, dated 13 Feb
2002, sized 241766 bytes) to IIS 5.0 (W2K SP2). Tomcat 4.0.2 works fine, but
when requesting a resource via IIS I got the message:

The specified module could not be found.

I deleted this filter, and downloaded and installed the ISAPI filter for
3.3. That works--IIS redirects the requests to Tomcat and a correct response
is generated. I made no other changes to IIS or Tomcat to get this to work.

Is there a bug in the new isapi_redirector.dll? Or are there additional
configuration steps needed?

Getting multiple instances of my servlet, although it doesn't implement SingleThreadModel

[Scott Shorter]

All,

I have a servlet that loads on startup, per the  tag
in web.xml.  It does *not* implement SingleThreadModel.

Unfortunately, two instances start up every time Tomcat starts - I can
tell because I have a System.out.println call in init().  I need for
there to be only one instance.

What other settings could be causing multiple instances to happen?

Thanks in advance,

RequestDumperValve help

[Mark Shaw]

I have a question (potential bug?) w/ RequestDumperValve.  I have set up a
simple SOAP like web-service (actually it's Caucho's Hessian protocol) and
when I attempt to use this when also using the RequestDumperValve, my call,
which uses POST, always fails on the server due to the servlet input stream
being close.  The Dumper logs all the correct values from the client
request, but my servlet is passed (from invokeNext()?) a closed input stream
so it can't read the SOAP request.  I poked around in the code and
discovered that this is related to HttpServletRequest.getParameterNames(),
and digging deeper still, found that code in
HttpRequestBase.parseParamaters() actually closes the input stream when
reading the params from a POST:
 
if ("POST".equals(getMethod()) && (getContentLength() > 0)
&& (this.stream == null)
&& "application/x-www-form-urlencoded".equals(contentType)) {
try {
int max = getContentLength();
int len = 0;
byte buf[] = new byte[getContentLength()];
ServletInputStream is = getInputStream();
while (len < max) {
int next = is.read(buf, len, max - len);
len += next;
}
is.close();
RequestUtil.parseParameters(results, buf, encoding);
} catch (Throwable t) {
;
}
}
 
Is there any reason is.close() is called?  Am I doing something wrong?
 
Thanks for any help on this,

 It's not really the same problem, but there's some 
info at:

 http://www.distributopia.com/servlet_stuff/background_threads.txt

 that might be of use. The second question has a list
of potential gotchas.

 Normally the servlet container is responsible for
controlling how threads are used. It knows about
things like your webapp being distributable, or
getting swapped out to disk, or reloaded, etc. If
you create your own threads, then you are responsible
for tracking all of that.

 Technically, the container provides you with all
the lifecycle notifications you need, but Java doesn't
have all the management tools to properly deal with
threads. You can get around (most of) the problems
with careful programming. (see the Doug Lea reference
in footnote 11)

No, it means that your servlet will match the "/" part, and anything
else will be returned to use as "extra path info".

For example, assume you have the above mapping in a webapp mapped to
context path "/myapp".  Now, a URL like this:

  http://localhost:8080/myapp//foo/bar.html

will call your servlet, which can then get the following:

  request.getContextPath() will return "/myapp"
  request.getServletPath() will return "/"
  request.getPathInfo() will return "/foo/bar.html"

Using extra path info is a common way to pass parameters to a servlet as
part of the request URL itself.  In addition, it totally hides the fact
that there is no static resource named "//foo/bar.html" in your app,
so the client has no way to know whether this response is being produced
dynamically or statically.

See the Servlet Specification for what everything in the web.xml file
means:

  http://java.sun.com/products/servlet/download.html

 SRV.11.2 Specification of Mappings, from version 2.3 of the
servlet spec, should have all the information you need. The
servlet spec isn't (for the most part) written in spec-speak, so
it's easy to read. You can download it at:

The input stream is closed because it has been completely read.  Even
without the close() there, though, you'd still have a problem because the
stream will have been read already, and there's no way to rewind it.

That wouldn't be a problem if the servlet only used getParameter() type
calls itself.  But if the servlet expects to read the input stream, and a
filter has already read it, you're violating the requirements of the
servlet and you'll need to do something different in your filter:

* Modify RequestDumperFilter to not dump the parameters

* Create a wrapper around the request before passing it on,
  and have the wrapper provide a suitable input stream
  even though the filter already read the "real" input stream.

Re: changing the default character encoding

[Richard Sand]

Hi all,

I am still beating my head against a brick wall trying to get the default
encoding changed for my Tomcat server on Linux (slackware 2.4.17 if it
matters).

The problem is actually outside of Tomcat so please excuse the slightly
off-topic question.  But basically, I've run the following simple test:

import java.io.InputStreamReader;
import java.io.ByteArrayInputStream;
public class Encoding {
  public static void main(String[] args){
byte[] bytes = new byte[0];
ByteArrayInputStream bs = new ByteArrayInputStream(bytes);
InputStreamReader in = new InputStreamReader(bs);
System.out.println("file.encoding is " +
System.getProperty("file.encoding"));
System.out.println("default encoding is " + in.getEncoding());
  }
}

And no matter what I try, it always says "default encoding is ASCII", no
matter what I've specified file.encoding as.  I'm invoking the class as:

java -cp $CLASSPATH:. -Dfile.encoding=ISO8859_1 Encoding

I've tried the following values for file.encoding with no changes:

ISO8859_1
ISO-8859-1
8859_1
iso-8859-1
iso8859-1
iso8859_1
en_US
no_NO
norwegian

I've also tried every one of those values for LANG and LC_ALL in my
environment variables.

Please, someone help me! How do I change the damned default encoding
Why isn't it picking up on my environment variables or the file.encoding
property? Running "java -version" tells me:

java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

Can anyone help? I'm totally stymied here!

encoding "Cp1252" is not supported

[Sam NewYork]

I recently installed Cocoon2 with JBoss-2.4.3_Tomcat-3.2.3.  I followed all 
the instructions on the installation page which involved removing parser.jar 
and jaxp.jar and replacing that with xerces-1.4.4.jar

Now when I try to work with my JSP files in another webapp outside of
cocoon, I get the following message:

Internal Servlet Error:

org.apache.jasper.compiler.CompileException:

My taglib.tld in the ecp webapp explicity has an ISO-8859-1 encoding in it.  
I think this has to do with xerces since I changed the parser.jar.
Any one have any ideas what's going on?  If I should be asking another

Any help will be appreciated.

Mind if I ask why you have a 0 byte buffer here? (Although perhaps it
wouldn't matter for what you're testing.)

> ByteArrayInputStream bs = new ByteArrayInputStream(bytes);
> InputStreamReader in = new InputStreamReader(bs);

I tried this:

  InputStreamReader in = new InputStreamReader(bs, "US-ASCII");

(Shift_JIS is the usual for me.) I had to declare the main method as "throws
UnsupportedEncodingException" to get it to compile, but the responded with
the changed encoding when run from the command line.

So it looks like it might be a Tomcat question? But I think I recall seeing
some answer on the list or in the docs. It may come down to having to
declare the encoding from your web pages, or read it from the headers the
browser sends or something.

Not much help, I suppose.

RE: Jetty .vs. tomcat

hi Steve,

I'm a Tomcat user. from what I read on the web, I believe Jetty does
outperform Tomcat significantly in static pages and also outperform Tomcat
to a unknown degree in dynamic pages. so, why i still choose Tomcat?

My main consideration is in scalability. Multiple instance of Tomcat can be
run and load balanced with Apache and mod_jk. I believe it can achieve a
very high scalability in handling simultanceous requests. Other
considerations are: good integration with other Apache and commercial
products, better support (i personally think the 'support' from Apache group
is better than other open src groups), full implementation of JCP
specification etc.

And Tomcat should not be used together with Apache if there is heavy loading
of static pages.

Other than Tomcat and Jetty, Resin is also quite famous. And there are other
commercial choice like WebLogic, JRun and Orion.  You should make decision
base on your need.

In my opinion, if your site is small in scale, and requires a very good
response time, then Jetty or Resin are your choice. Otherwise, Tomcat is a
good choice in general and it is a proven product. It occupies about 50% of
the servlet engine market as of mid 2001.
