Re: ?? Class Loaders, Static Initializers, Open Files ??

[Phillip Morelock]

Unfortunately I believe that's what static initialization is.

It's not totally clear whether this will help you, but here's a link 
that describes the order things are done in:

RE: Problem: JSP calls singleton. Singleton's data changes, but JSP s till shows old data from that singleton

[Chris Campbell]

Assuming the browser is not just giving you a cached page, in the servlet,
if you log the contents of _instance just before return _instance; do you
see the new data?

RE: Classloader question

[tamir]

Hi,
I had many problems with classloaders using tomcat 3.3.1.
I think you shouldn't be suprised by the LinkageError, cause you actually
load this class twice, once by the context class loader and second by the
apps
class loader.
What I don't remember is the hirarcy between these two class loaders
(maybe you can check in the archives, and understand better what's
happening).
What I don't understand is why using two different versions of the same
class.
Isn't it some kind of troublemaker?

Subject: Classloader question


Hello,

I have a situation with Tomcat 3.3a where I am trying
to allow a specific servlet context to load a version
of a class from within their WEB-INF/classes
directory, while other contexts on the server use a
different version of that class that is loaded by the
apps classloader.

I can currently get the context classloader to
actually load the correct class, however later on
during init, I am getting a java.lang.LinkageError
saying that the specific class that is being loaded
twice is violating the loader constraints.

Can anyone point me to any resources that would help
me solve this problem? Any similar experiences or
ideas would be greatly appreciated.

Thanks in advance,

Mario-

tomcat4 apache mod_jk : problem in setup

I am refering packages and text from

 following error.

and It's not working. 
I have searched on the web for same errors and solutions, but could not get any.

Please tell me if anyone has got tomcat4 working with mod_jk connector. If so please give me details like
- from where to download packages
- where to find the steps to follow for this

Or do I need to recompile mod_jk.so to get it working?

R: implicit object servlet

[Alessio Fiore]

I think you're talking about struts...
AFAIK a taglibrary is not directly related to a servlet, but a tag handler
has access to the request, where struts sets an attribute for each
datasource, which name is corrisponding to datasource's key attribute:

HttpServletRequest req = (HttpServletRequest)(pageContext.getRequest());
DataSource ds =
(DataSource)(req.getAttribute("your-datasource-key-attribute-value"));

Alessio

Why would you build a EJB web application *without* JSP? :-)

Anyway, it is really a rule of thumb and your general mood. Even now, I use regular 
Beans which do preety much the same job as EJB, only simplified. I haven't gotten 
JBoss up yet, but even with a very simple example I find EJBs appealing.

Re: tomcat4 apache mod_jk : problem in setup

[Bernd Koecke]

Hi,

this is a problem with the build.xml scripts. I had the same problem, too. Your 
apache seems to be compiled with -EAPI, e.g. for mod_ssl. I don't know if there 
is a compiled dso with EAPI enabled. I build the connectors on my own with cvs 
repository from jakarta-tomcat-connectors. You find infos in the doc directory 
of thsi package. When you want to use mod_jk form jk1 in directory jk/native, 
adding the line



in the platform specific tags of the apache13 target of file 
/jk/native/build.xml will build a mod_jk.so which uses EAPI.

Problem with Tomcat 4.1.0 & IIS

[Carlos Martins]

Title: Problem with Tomcat 4.1.0 & IIS






Hello,


I have recently upgraded to Tomcat 4.1.0

Also upgraded my isapi_redirect.dll with the version located in http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3/bin/win32/i386/

I have IIS as web server and Tomcat listening to redirections through the Coyote JK 2 connector.


Now my web site is not working - only some pages are not displayed and the following message is placed in the log file:

"Connection reset by peer: socket write error"


But if I run my web site through the HTTP1.1 connector of Tomcat (port 8080) it works fine - all pages are properly displayed.

Any clues?


Thank you very much

Carlos

RE: SSL certificate help!

Hi Raj,

thanks for your detailed mail which was very helpful. I had followed the
same.,
but i had another question. The certificate from verisign has been placed
as instructed , but how do i enable the client i.e browser in my case for
the
same . does anything specific has to be done?

prior to doing this, i was using a self-signed certificate, which the
browser still
reads. how to make the browser know abt the verisign cert? hope u got
the point. 
thanx in advance

Hi,

Follow these steps to configure your digital id

1. generate a local certificate:
   keytool -genkey -alias tomcat -keyalg RSA -keystore  where
 is the name of the desired keystore-file

2. generate the CSR (you need it to request your (demo)certificate)
   keytool -certreq -keyalg RSA -alias tomcat -file certreq.pem
-keystore

   now you have a file called "certreq.pem". Send this to your
trustcenter.

Note : You can skip steps 1 & 2 becoz u said, u already got a verisign
certificate. But make sure that u have done these steps only to send your
demo cert. to verisign.

3. Goto verisign & download TrustedCA Root Certificate which they give for
the browser. The downloaded file name would be getcacert. Now use the
following command to import that into trust store

keytool -import -alias root -keystore  -trustcacerts -file


4. Now import your verisign certificate with this command

keytool -import -alias tomcat -keystore  -trustcacerts -file


With the above 4 steps, u r ready with your keystore. Now goto server.xml &
search for ""

Uncomment the above line & add the following changes

 

I think this should solve your problem. All the best.

Regards,

..Raj

Terminating sessions problem. (bug?)

[Garzon Maldonado, Jesus Javier]

Hello all:

When a user enter in my site sessions are used to store user data. I get the 
session using (request.getSession(true);). When users leave the site the session is 
invalidated (request.getSession().invalidate();). But, if users enter again from the 
same browser instance each call to (request.getSession(true);) creates a new session 
so it's impossible to get data associated with the session from differents servlets. 
If users enter from another browser instance, sessions works fine.

I'm using Apache 1.3.20 + Tomcat 4.0.3 on windows NT, but this also happened with 
Tomcat 3.2.1 and on unix platforms running Tomcat 3.2.1 standalone.

This is a bug?, Am I doing something wrong?

Older browser versions (for exemple IE4 ...) don't support 128 bit
encryption rate. Is there a way to configure tomcat to deny all requests

The SSL connection, using the configuration as described in "SSL How To",
reduces the encryption rate automatically to a level, the client is
compatible to.

I have found the same using jb241a+tc323 as well as jb300RC2+tc403.

I started looking at the tomcat code but I'm not sure I want to commit the time it may 
take to understand the intricacies when someone 
else may well have an answer.

I'd like to know whether this is worth pursuing or if perhaps it is better to 
sacrifice the declarative model for a role-your-own approach.

Hi, have a look for postings titled 'How to enforce SSL' that were posted
over the last few days. Assuming you have gone through the How-to-SSL
document in the tomcat docs and set up a certificate, to enforce SSL for a
certain directory in your context, you need something like this in your
web.xml.


  

  Entire Application
  /*


  trackeruser


  CONFIDENTIAL

  

  
  
BASIC
Location Tracker Application
  

The important piece is the user-data-constraint and the
transport-guarantee. This tells tomcat that all requests to the url pattern
(in my case it is the whole of my context) should be sent over HTTPS. If a
request is received over HTTP, tomcat will redirect the request at whatever
port is defined in server.xml as the 'redirectPort' for the HTTP connector.
This is probably 8443. You then need to make sure that you have an SSL only
connector on that port but I guess you should already have that if you've
got the SSL working already.

Cheers.

Steve.

Hi All,

My application requires that certain pages on the site are accessed via
SSL,
is
there a way in tomcat to reject the connection of http to a specific page
(ie securePage.jsp) but still allow http access to other pages (ie.
standardPage.jsp).

Also i'm using cookies - so i wanted to know whether these cookies will
be visible in both the http & https contexts.

Thanks in advance,

Ritesh

Processes

[tomcat]

Hello
I'm using
Tomcat 4.03
Apache 1.3.23
J2SDK 1.4
RH 7.2

In this server are running 4 private tomcat instances, and 6 sites in
a shared instance.
What I saw while I was doing a top, its the HUGE number of processes
running, usually goes over 2200 processes.
I set a cronjob to restart to restart apache and tomcat every hour,
trying to clean memory and processes.
I was wondering if its possible to cut the number of the processes, or
if I can put hard limits to each instance.

None of this sites have more than 1 GB of traffic per month.

Thanks in advance for anyone who can help me here.

Hi there try putting <%@ page import="ant\uci\edu" %>

Your complete dir path of your .class file in your jsp page ( page 
directive) as a apparently the class loader points to classes default 
package in j-tomcat3.3a but you can't get away from it in j-tomcat4 
upwards . I had a similar problem thus useing tomcat3.3.a for now and 
i'll upgrade and use the  classes dir path and page import directive as 
told via this user-help group.

Tomcat memory problem ?

[Laura]

Hi all,

my system is this: I have a solaris machine (2GB RAM) with apache 1.3.19 and 
two instances of Tomcat 4.0.3 in a load balancer configuration.

I started all three days ago: this morning I have found the two Tomcat dead. 
All my servlets didn't respond and all the system was dead.

It's terrible.

Did someone ever have this problem?
Often I read in the mail list that there is some problem in memory in Tomcat: 
is it true?

Does someone know something?

RE: Classloader question

[Larry Isaacs]

The classloader diagram is found at:



Because Tomcat 3.3.x uses the JDK delagation model for
classloading, classes in the "apps" classloader take priority
over WEB-INF/classes and WEB-INF/lib.  I don't think your
approach will work because of this.

However, there is an alternate trick that might work if you want
to give it a try.  Instead of placing the "shared" classes in the
"apps" class loader, place them somewhere else and "include" them
in the webapp class loader using the additionalJars attribute of
the LoaderInterceptor11.  See:



I believe the additionalJars attribute will take directories as
well as jars.  I also believe the "additionalJars" will be
searched after WEB-INF/classes, so a different version of a
class in WEB-INF/classes will take priority over classes added
by "additionalJars".

Larry

  Hello there, I am running Tomcat 3.3.1 and JDK1.4
under Mandrake Linux 8.1 and I have a problem finding
the MySQL drivers. I have looked on the Tomcat
archives and could not find any similar questions, so
I thought I am going ot try the mailing list.

  I have created my own web app space and I have
managed to run Servlets and JSP pages successfuly but
when I am trying to load the MySQL drivers it fails
with the "java.sql.SQLException: No suitable driver"
error message. I have put the mm.mysql-2.4.0-bin.jar
file under my webapp's WEB-INF/lib folder
(WEB-INF/lib/mm.mysql-2.4.0-bin.jar) but it does not
seem to work. I thought Tomcat was going to pick it up
automatically but obviously this is not the case. I
have set up the CLASSPATH to point to the .jar file
but still no luck. I have to tell you here that I can
load it from a Java application but not from a JSP
page.

  Any help is greatly appreciated.

  Kind regards

SessionMgmt: No Cookies sent - Instead only URL-Rewritting active - Why?

[Lerenc, Vedran]

Hi,

I was using Tomcat 3.2.1 and switched to Catalina 4.0.3 (both on Windows
2000). Now my browser (IE6.0 on Windows 2000) gets no cookies anymore. It
seems that the session management ist now handled using URL rewritting and I
don't know why.
When I test my web application using Tomcat, I get the following response:

  HTTP/1.0 200 OK
  Content-Type: text/html
  Content-Encoding: gzip
  Set-Cookie2: JSESSIONID=k76kokd041;Version=1;Discard;Path="/"
  Set-Cookie: JSESSIONID=k76kokd041;Path=/
  Servlet-Engine: Tomcat Web Server/3.2.1 (JSP 1.1; Servlet 2.2; Java
1.3.0_02; Windows 2000 5.0 x86; java.vendor=Sun Microsystems Inc.)

When I test my web application using Catalina and the same browser (just
restarted), I get the following response:

  HTTP/1.1 200 OK
  Content-Type: text/html
  Date: Tue, 07 May 2002 12:15:41 GMT
  Content-Encoding: gzip
  Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
  Connection: close

The problem is: I am not running without cookies and need them back. Is
there a config setting I have to make somewhere?

I have not configured my web application explicitely in the server.xml file.
When I do that similar to the settings for the "examples" context shipped
with Catalina, I also don't get any cookies for my web application. Though,
for the "examples" context Catalina generates cookies:

HTTP/1.1 200 OK
Content-Type: text/html
Date: Tue, 07 May 2002 12:30:19 GMT
Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
Connection: close
Set-Cookie: JSESSIONID=9CD291E4F769E034E28F2E97BF40FEDC;Path=/examples

Why for the "examples" context and not for mine? Does anybody know, how to
alter this behaviour and enforce cookies to be sent back to me for my web
application?

Cheers,

Vedran

IIS5 and tomcat 4.0.3 via AJP

[simpson]

sorry if this is an annoying starter question but i have so far not been
able to retrieve the list faq.
 
i have IIS5 , J2SE 1.4 , J2EE 1.3.1 , tomcat 4.0.3 , and isapi_redirect.dll
installed on W2K server SP2.
isapi_redirect was downloaded from
http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3/bin/win32/i386/
isapi_redirect.dll
  as specified in the tomcat docs - AJP.HTML.
 
everything works fine when browsing on port 8080 , but trying to use port 80
causes an internal server error to be returned.
i have been over the setup many times and don't see the problem , i can't
find any indication in any log files as to what the actual problem may be.
my guess is that the tomcat docs are out of date and that the
isapi_redirect.dll v3.3 will not work woth tomcat 4 ??
 
maybe i have this concept wrong but i though that if i can access resources
directly via tomcat on 8080 using
http://127.0.0.1:8080/examples/jsp/index.html
  , that i should then also
be able to access the same via IIS / AJP using
http://127.0.0.1/examples/jsp/index.html
 .
 
the iis_redirect.log file shows :

RE: Terminating sessions problem. (bug?)

But the question is, If I invalidate one session I can't use the same browser to login 
again, because the session is created every time I call request.getSession(true), 
nevertheless if I don't terminate the session, and the session never time out, then 
the server will store large amounts of sessions that no longer will be used.

i'm ok with you but I have to do that each time I think there is an
other way to do it from a servlet or a jsp. Like in asp with the "header".

RE: Classloader question

[tamir]

Hi Larry,
As I understand the additionalJars attribute, it can actually state jars
outside
the WEB-INF/lib or WEB-INF/classes that will be reloaded by tomcat when one
of the jars in changed.
Is it also relevant for Catalina ?
(Is there a way to state jars to be reloaded there too ?)

The classloader diagram is found at:



Because Tomcat 3.3.x uses the JDK delagation model for
classloading, classes in the "apps" classloader take priority
over WEB-INF/classes and WEB-INF/lib.  I don't think your
approach will work because of this.

However, there is an alternate trick that might work if you want
to give it a try.  Instead of placing the "shared" classes in the
"apps" class loader, place them somewhere else and "include" them
in the webapp class loader using the additionalJars attribute of
the LoaderInterceptor11.  See:



I believe the additionalJars attribute will take directories as
well as jars.  I also believe the "additionalJars" will be
searched after WEB-INF/classes, so a different version of a
class in WEB-INF/classes will take priority over classes added
by "additionalJars".

RE: ?? Class Loaders, Static Initializers, Open Files ??

[Cox, Charlie]

you can move it to \common\lib which is loaded by a different class loader,
but then it will be visible to all contexts.

Using a static initializer like that will also cause problems if you try to
use the manager to control your app since manager drops the classloader and
creates a new one when you reload.

maybe instead of a static initializer, you can use a servlet's init() and
have it load on startup. This way you can use a class and utilize the
destroy() method to do your cleanup.

you could also try setting the HTTP Expires header to something definitely

something like response.setHeader("Expires","1/1/1980");

Help with hiding resources

[Kris Kras]

Hello all,

I have an application using jsps, servlets and applets runing under Tomcat
4.03 and Struts 1.0 (win2k server).
My application is located under "C:\Tomcat4\webapps\applications\" and all
jsp files are there. Some jsps launch applets through  tags.
Applets are packaged in jars located in
"C:\Tomcat4\webapps\applications\jars\". A code fragment launching applets
looks like this:
http://www.domainmame.com/applications/jars/"; or
"http://www.domainmame.com/applications/jars/myapplet.jar"; and ultimatelly
decompiled. I would like to hide the resources (jar files and everything
else that is located in subdirectiories of "\applications\". I have tried
putting the jar files in "C:\Tomcat4\webapps\applications\WEB_INF\lib\"
where all other jar files (struts.jar, etc.) are located, but then
regardless of what I used for "archive" and "codebase" parameters in
 tag I get and file not found exception in the plugin console
(java.io.FileNotFoundException:
http://www.domainmame.com/applications/WEB-INF/lib/myapplet.jar) even though
the jar file is there.

I have tried setting the following values for "archive" and "codebase"
parameters in  tag with the jar file in
"C:\Tomcat4\webapps\applications\WEB_INF\lib\":

  archive = "myapplet.jar"
  codebase = "."

  archive = "/WEB-INF/lib/myapplet.jar"
  codebase = "."

  archive = "myapplet.jar"
  codebase = "/"

  archive = "myapplet.jar"
  codebase = "/applications/WEB-INF/lib/"

None of the combinations worked. Can anyone help me with configuring these
two parameters so the Tomcat can find myapplet.jar.

Or is there a better solution to hiding resources under Tomcat.

Any help would be greatly appreciated.

Thanks

Kris

I haven't actually tested the additionalJars feature with

specify use11Loader="true" for jar reloading to work.

I'm not aware of an equivalent feature in Tomcat 4.x.

RE: shutdown.sh doesn't shutdown JMV

[Shapira, Yoav]

Howdy,
Check for non-daemon threads still running somewhere in your apps, or
3rd party code you apps use.  Tomcat 4.0.2 eliminated the System.exit()
call in the shutdown code, for better compliance with embedded tomcat
users.

There's a thread about System.exit(), check the archives ;)  See also
the Thread docs about shutting down daemon vs. non-daemon threads.

RE: Re[4]: file path problem

jake,
  your explanation is excellent. I completely understand whats going on
now.. but again a quick question.. In jetspeed, we have template files under
Web-inf directory but the template directory is mapped in
jetspeedResources.properties file. So i should be able to access the
templates under Web-inf directory as jetspeed does. 


thanks

-Original Message-
From: Jacob Kjome [mailto:[EMAIL PROTECTED]]
Sent: Monday, May 06, 2002 5:40 PM
To: Tomcat Users List
Subject: Re[4]: file path problem


Hello Bharanidharan,

Ah, I didn't see that before.

You don't want to store your static files under WEB-INF.  That is
purely for servlets and other general classes and some config stuff
such as the web.xml that you don't want to have directly accessible
via the web.

You would put your html file one directory up from WEB-INF in your
"jetspeed" directory.  This is also where you would put .jsp files.

Also, you don't actually have to provide the /servlet/* mapping in
your own web.xml.  You will get that functionality already because it
is in Tomcat's default web.xml.  All you need to know is that it is
the functionality that it provides.

Now, keep in mind that nothing within WEB-INF will be accessible
without some sort of mapping.  We are using the default /servlet/
mapping that Tomcat provides.

So, when you see:

http://www.myhost.com/jetspeed/servlet/myservlet.NewLogin

The "/servlet" part of of that URL is virtual.  The mapping is
provided by the web server.  The request goes through an invoker
servlet that runs the requested servlet for you.  That is much different
than going to your
html file which should be at...

http://www.myhost.com/jetspeed/templates/vm/navigations/html/loggedinportlet
.html

Although, that assumes that you would move the root of "templates"
into the "jetspeed" directory rather than have it exist under the
WEB-INF directory.

As you can see, the server needs no mapping information for static
files other than knowing what directory or virtual directory
http://www.myhost.com/jetspeed/ points to.  After that, you just
follow the directory structure within the "jetspeed" directory to
determine the URL path to the static document.  This is not so with
servlets.  You can't just browse to a servlet at some physical path on
the disk.  You refer to servlets through servlet mappings.

BTW, if you created a directory called "servlet" to store static
files, you wouldn't be able to get to them because Tomcat would
intercept the pattern /servlet/ and try to map the named entity that
comes after that rather than serving the named entity directly from
that directory.

For instance, if you had:
/webapps/jetspeed/servlet/templates/vm/navigations/html/loggedinportlet.html

and tried to get to that page via:
http://www.myhost.com/jetspeed/servlet/templates/vm/navigations/html/loggedi
nportlet.html

Tomcat would report an http 404 error because it tries to find a
servlet to invoke named
"templates/vm/navigations/html/loggedinportlet.html" or with a
class name of "templates/vm/navigations/html/loggedinportlet.html"

Which brings to mind another trick.  You can name your servlet and get
there via the servlet-name rather than having to specify the whole
package + Servlet class name adding the following to your web.xml:


newlogin
myclasses.NewLogin


Now you can get to your servlet via the class-name:

http://www.myhost.com/jetspeed/servlet/myservlet.NewLogin

or via the servlet-name:

http://www.myhost.com/jetspeed/servlet/newlogin

You can also, then, provide your own mapping for the servlet named
"newlogin" such as:


newlogin
/login


which allows you to get to your servlet without having to go through
the default /servlet/ mapping like this:

http://www.myhost.com/jetspeed/login

notice that the "servlet-name" in "servlet" and "servlet-mapping" must
be *exactly* the same (case sensitive too).


Does that make more sense or did I just add to the confusion?

Hi Larry,
Tnx for your information,
I'm afraid I can't use this feature as It's not compatible with

I haven't actually tested the additionalJars feature with
respect to reloading. It was orignally added with non-changing
jars in mind, jasper.jar specifically.  You may have to also
specify use11Loader="true" for jar reloading to work.

I'm not aware of an equivalent feature in Tomcat 4.x.

Cheers,

RE: Help with hiding resources

[Kris Kras]

Thank you Alessio,
does this mean that if I put the jar files in WEB-INF/lib directory they
will be invisible to the browser? The WEB-INF/lib directory is a
subdirectory off of the Root directory called "applications", which is the
directory hosting the jsp files launching the applets and as such it should
be accessible by the applet that the codbase points to applications
directory (at least this is my understanding). Does Tomcat prohibit the html
page generated by the  from accessing the jar files in the
WEB-INF/lib directory?  And if so do they have to be in a generic directory
off of the root directory?

Sorry if my mumbling is confusing I am just trying to understand what my
options are.

Thanks

Oggetto: Help with hiding resources


Hello all,

I have an application using jsps, servlets and applets runing under Tomcat
4.03 and Struts 1.0 (win2k server).
My application is located under "C:\Tomcat4\webapps\applications\" and all
jsp files are there. Some jsps launch applets through  tags.
Applets are packaged in jars located in
"C:\Tomcat4\webapps\applications\jars\". A code fragment launching applets
looks like this:
http://www.domainmame.com/applications/jars/"; or
"http://www.domainmame.com/applications/jars/myapplet.jar"; and ultimatelly
decompiled. I would like to hide the resources (jar files and everything
else that is located in subdirectiories of "\applications\". I have tried
putting the jar files in "C:\Tomcat4\webapps\applications\WEB_INF\lib\"
where all other jar files (struts.jar, etc.) are located, but then
regardless of what I used for "archive" and "codebase" parameters in
 tag I get and file not found exception in the plugin console
(java.io.FileNotFoundException:
http://www.domainmame.com/applications/WEB-INF/lib/myapplet.jar) even though
the jar file is there.

I have tried setting the following values for "archive" and "codebase"
parameters in  tag with the jar file in
"C:\Tomcat4\webapps\applications\WEB_INF\lib\":

  archive = "myapplet.jar"
  codebase = "."

  archive = "/WEB-INF/lib/myapplet.jar"
  codebase = "."

  archive = "myapplet.jar"
  codebase = "/"

  archive = "myapplet.jar"
  codebase = "/applications/WEB-INF/lib/"

None of the combinations worked. Can anyone help me with configuring these
two parameters so the Tomcat can find myapplet.jar.

Or is there a better solution to hiding resources under Tomcat.

Any help would be greatly appreciated.

Thanks

Kris

Yes, WEB-INF and META-INF subdirs of a tomcat context root directory are not
accessible externally (so the browser doesn't have access to any file under
these dirs). They're just accessible internally (by the server-side
application). Your applet files (.class or .jar) must be visible by the
browser, because their reference is put in JSP-generated HTML page (that is
parsed and managed by the browser itself), so you have to put them under a
subdirectory of "applications" other than WEB-INF.

Re: Should i use J2re instead of jdk in my Tomcat server ?

[Jeff]

Assuming that there aren't any other problems lurking in the darkness,
installing the j2sdk should fix the problem.

Remember, .jsp pages are REALLY templates used by Tomcat to automatically
build and compile servlets. Without the j2sdk, Tomcat can't compile the
servlets, and .jsp pages won't work. There are probably other reasons why
the j2sdk is necessary, but this is the Big One.

Hi Kris, the jar that contains the applet and related classes *must* be
accessible by the browser. If not the browser could not load it and extract
the applet (throwing the java.io.FileNotFoundException).

Oggetto: Help with hiding resources


Hello all,

I have an application using jsps, servlets and applets runing under Tomcat
4.03 and Struts 1.0 (win2k server).
My application is located under "C:\Tomcat4\webapps\applications\" and all
jsp files are there. Some jsps launch applets through  tags.
Applets are packaged in jars located in
"C:\Tomcat4\webapps\applications\jars\". A code fragment launching applets
looks like this:
http://www.domainmame.com/applications/jars/"; or
"http://www.domainmame.com/applications/jars/myapplet.jar"; and ultimatelly
decompiled. I would like to hide the resources (jar files and everything
else that is located in subdirectiories of "\applications\". I have tried
putting the jar files in "C:\Tomcat4\webapps\applications\WEB_INF\lib\"
where all other jar files (struts.jar, etc.) are located, but then
regardless of what I used for "archive" and "codebase" parameters in
 tag I get and file not found exception in the plugin console
(java.io.FileNotFoundException:
http://www.domainmame.com/applications/WEB-INF/lib/myapplet.jar) even though
the jar file is there.

I have tried setting the following values for "archive" and "codebase"
parameters in  tag with the jar file in
"C:\Tomcat4\webapps\applications\WEB_INF\lib\":

  archive = "myapplet.jar"
  codebase = "."

  archive = "/WEB-INF/lib/myapplet.jar"
  codebase = "."

  archive = "myapplet.jar"
  codebase = "/"

  archive = "myapplet.jar"
  codebase = "/applications/WEB-INF/lib/"

None of the combinations worked. Can anyone help me with configuring these
two parameters so the Tomcat can find myapplet.jar.

Or is there a better solution to hiding resources under Tomcat.

Any help would be greatly appreciated.

Thanks

Kris

Some JSP and Beans Questions

[Frederick Aubert]

Hi,

My questions will look pretty stupid to the experts, so to avoid bugging
everyone on this list, I¹d suggest that if you want to answer them, you can
address me directly at [EMAIL PROTECTED]

I tried to build an html form linked via JSP to a Java Bean. I then tried to
access the object instantiated from the field values obtained from the form.
Everything went fine as long as I kept using associated get/set methods. I
then tried to add a new method ³connect² to my bean, just to keep things
simple I made this method not taking any parameter not returning anything
and not doing any computation, but as soon as I tried to call it it launched
a bunch of exceptions and errors. Any idea? Is it forbidden to add such
method to a bean?

I also tried to create some multiple selection box (ie. You have a box of
given values, where the user can pick any number 0-max). I then tried to get
XXX parameter back using the automated conversion into a bean with property
XXX being of type java.util.Set, but I found myself stuck when I add to
implement the setXXX method. How can I achieve this multiple arguments
recuperation?

Thanks, Frederick

RE: Strange JSP Problem

[Collins, Jim]

It is not the JSP itself that is causing the problem because in some cases I
can run it. I have a servlet that I use to launch all other servlets that
are typically located on NFS not under the WebRoot. When I load a JSP I copy
the JSP to the WebRoot and then instantiate JspServlet and get this to
service the request. This normally works fine unless I use a symbolic link
and Tomcat complains that the file name is to long. But when this happens I
can't display any JSP, I just get a blank screen. I did try deleting the
generated .java and .class files in the work directory and then refreshing
the web page, this did not work though the files were generated again but
the resulting html had no content.

Thanks

Jim.

Re: Tomcat redirect

[joshua wentworth]

I was hoping of something within the Tomcat configuration itself since we
don't use an index.jsp file. To be more specific about my problem, Whenever
a servlet calls another servlet in Tomcat it isn't intercepting the
/servlet/ directive and replacing it with /spike/servlet/ which is what it
should be doing. Perhaps I'm overlooking something obvious in the
configuration that will do this, but I've tried putting a




Entry in the server.xml file, but that didn't seem to do it either...
Someone smack me with a clue stick and tell me what I'm doing wrong?

Re: SessionMgmt: No Cookies sent - Instead only URL-Rewritting active

[Jeff]

I've observed the same phenomenon.

It's just a theory, but I suspect it might have to do with Internet Explorer
6 itself. I think Microsoft quietly changed IE6's default cookie-acceptance
behavior to automatically reject all cookies from sites not meeting its
criteria for auto-acceptance. Taking a wild guess, IE6 might now
automatically reject cookies from sites accessed via IP addresses that don't
resolve to a hostname.

Another possibility: a few years ago, when anti-cookie hysteria was being
fanned by magazines eager to scare naive readers and people were disabling
cookies for stupid reasons (like thinking a "malevolent cookie" could
reformat their hard drive), Microsoft quietly introduced a special anonymous
cookie-in-all-but-name ("session id") that persisted only for the duration
of a single session (I think it even went away if you browsed to another
site or were inactive for more than an hour), but could not be disabled (so
IIS could depend upon its availability and use it to track users from page
to page within the session and match the correct IIS session variables with
the right user).  I'm not sure whether Tomcat and other servlet containers
take advantage of it (or whether they'd even be ABLE to without lying to the
browser and pretending to be IIS), but I see two likely scenarios:

1) Tomcat (and other servlet containers) can't/don't use the special
anonymous session ID, and IE6 is now denying session-cookies by default
because something is triggering the behavior (non-resolvable IP, etc.)

2) Tomcat (and other servlet containers) DO use MSIE session IDs when
available, but IE6 now denies even THAT to sites that fail to meet its
criteria for acceptablity (possibly holding sites openly running a server
other than IIS to a higher standard)

>I was using Tomcat 3.2.1 and switched to Catalina 4.0.3 (both on Windows

Re[6]: file path problem

[Jacob Kjome]

Hello Bharanidharan,

Glad I could help :-)

As for your new questionwell, only if you loaded the template in the servlet and 
then had the
servlet return the result in the response.  You wouldn't be able to
get a direct connection to the template inside the WEB-INF directory
from a browser requested http call.  You can access anything you want
anywhere on your system on the server-side with Java.

What are these "templates"?  Are they html files that are supposed to
be served up by the web server without modification?  To me,
"template" means that it provides a general structure that is ready to
be filled in with data.  That would be done by loading the template up
in the servlet, dynamically adding data where specified in the
template, and then returning the result of the structure + data to the
web client.

Maybe I'm misunderstanding something because I've never worked with
jetspeed, but that should be the way it works.

Jake

Disabling URL Rewriting and relying on cookies

[Stephanos Piperoglou]

I'm developing a Web App on Tomcat 3.2.4 (and Struts 1.0.2) and I've
been using URL rewriting throughout to make everything nice and
relocateable. As has been pointed out before on this list, the first
time a browser accesses the web-app, the session id cookie is set but
cannot yet be retrieved so URL rewriting is performed even though the
browser supports cookies.

This causes all kinds of problems I want to avoid. The
";jsessionid=foobar" method is just too clunky and doesn't work well
with several other bits of the whole that don't recognise it as a query
string (a good example is when I use the Struts  tag to
set the codebase for an applet; also IE's visited links, autocomplete
passwords and other history-related functions don't work because IE
thinks it's a different page, other exaples too), and I desperately want
to disable it. Is there any way to disable session tracking via URL and
require cookies instead? They're a hard requirement for the webapp
anyway (for other reasons).

Hi, have a look for postings titled 'How to enforce SSL' that were posted
over the last few days. Assuming you have gone through the How-to-SSL
document in the tomcat docs and set up a certificate, to enforce SSL for a
certain directory in your context, you need something like this in your
web.xml.


  

  Entire Application
  /*


  trackeruser


  CONFIDENTIAL

  

  
  
BASIC
Location Tracker Application
  

The important piece is the user-data-constraint and the
transport-guarantee. This tells tomcat that all requests to the url pattern
(in my case it is the whole of my context) should be sent over HTTPS. If a
request is received over HTTP, tomcat will redirect the request at whatever
port is defined in server.xml as the 'redirectPort' for the HTTP connector.
This is probably 8443. You then need to make sure that you have an SSL only
connector on that port but I guess you should already have that if you've
got the SSL working already.

Cheers.

Steve.

RE-Initialize the servlet with Tomcat

["Bührle, Martin, FCI1"]

Hi List,

we are using
Tomcat 4.0.1
mod_webapp / WARP-Connector
Apache 1.3

The servlet we are using is a CMS-System (opencms). When we are changing
Web-Content in the CMS-database we see the changes in tomcat (Port 8080)
immediately, but not in the Pages served by Apache.

The problem is, that even a Apache-Restart is not enough. We have to restart
Apache AND Tomcat to see the changes in the CMS-pages via
Apache/WARP-Connector/Tomcat.

Is there a possibility to "restart" Tomcat or the servlet "OpenCMS" in a way
that existing connections are not affected and that we can see the changes
within the content of the servlet?
I saw something like "reloadable=true" in server.xml-file, but HOW does this
work together with the WARP-Connector and Apache?

Thanks for help

Re[2]: Tomcat redirect

[Jacob Kjome]

Hello joshua,

Well, actually, all you've done here is specify a context called
"servlet" which has it's docbase sitting on the file system as
"/spike/servlet".  This would assume that you are on a Unix system and
you have a directory called "spike" off the root of your sytem with a
directory called "servlet" inside that.

In this case, the address to your webapp would be:

http://myserver.com/servlet/

However, I would avoid calling your context "servlet" because I think
it will conflict with the default servlet mapping that Tomcat provides
for you.  In fact I think you are confusing the /servlet/* mapping that Tomcat provides
for all webapps via its default web.xml with setting up a context.

Let's assume that you place your new context in Tomcat's 'webapps"
directory and it is called "myservlets".  You can either not bother
explicitly stating the  for this webapp in the Server.xml and
let Tomcat create a default one for it, or you can go ahead and
specify it like this:



The path says that requests to http://myserver.com/myservlets refer to
a Tomcat-served Servlet context.

The docBase says where the context's directory exists on the file
system.  Here, we are saying that it exists in the current directory
(relative the webapps directory).  You could also put this elsewhere
on your file system, but you must then provide a path relative to
webapps directory by saying something like "../../../../myservlets"
which says "myservlets" is located 4 directories back from wherever
the "webapps" directory exists or you can specify a hardcoded path
like "C:\myapps\myservlets" on windows or "/myapps/myservlets" on
Unix.

Now with that set up, calling your servlet that redirects to another
servlet might go something like this:

http://myserver.com/myservlets/servlet/MyRedirectServlet

which might redirect to another servlet "MyRedirectResultServlet"

You'd have to make sure that the redirection goes to
"/servlet/MyRedirectResultServlet" in order for Tomcat to catch this
request as a request to this other servlet.

Did that answer the question or am I missing something?  Bottom line,
rename your context to something other than "servlet" to avoid
confusion.

RE: help, JDBCRealm, Why Need to authenticate three times to login

[Barney Hamish]

If I were you I'd check the error logs or the jvm.stdout or whatever. It
could be that there is a problem creating the connection to the database to
authenticate the user. If this is the case there should be error messages
indicating problems connecting to the database.

Re: Classpath problems with Tomcat4 and RedHat 7.2

[Larry Meadors]

Do you have a CATALINA_HOME environment variable set? That might cause
this...

>>> [EMAIL PROTECTED] 05/07/02 09:21AM >>>
I am having problems reading a resource file I placed in 
/var/tomcat4/common/lib. I also tried placing it in 
/var/tomcat4/common/classes.

I wrote a small JSP which lists the classpath and I notice it prints
out as 
/var/tomcat/common/lib  (missing the 4). Does anyone know where this is

set?

Re: Does mod_webapp support name-based virtual TOMCAT hosts?

[Jeff]

Ah... ok, I just assumed that "Tomcat-Standalone" established the baseline
values that got inherited by the "Tomcat-Apache" service and were used
absent a conflicting value there.

There's still one problem, though...  I changed the appBase in the
Tomcat-Apache section to an absolute path (/export/home/jeff/tomcat), but
it's still being ignored, and Tomcat is still trying to deploy the app into
/usr/local/jakarta-tomcat-4.0.3-LE-jdk14/webapps/ (/usr/local/tomcat is a
symlink) instead.

Is this a bug with Tomcat or mod_webapp, or am I still doing something
wrong? I know that Java itself would consider "/export/home/jeff/tomcat" to
be a relative pathname under Windows (because it doesn't begin with a drive
letter), but this is running under SunOS5.8 ... so if it's being interpreted
as relative, I don't know what it could possibly be relative TO since it
begins with a slash ;-)

As an alternate theory as to what might be wrong, are there any requirements
that all the directories LEADING UP to /export/home/jeff/tomcat (/export,
/export/home, and /export/home/jeff) be read/execute for any particular
group or user, or is it sufficient for just appBase
("/export/home/jeff/tomcat") and its contents to be read/write/execute? It
hasn't bitten me in a while, but years ago I went through lots of grief over
APACHE's refusal to serve files unless it had permission to traverse the
ENTIRE path (from / to the directory)...

Thanks!

Appending to TOMCAT's class path

[Tim Cronin]

the startup scripts (under 4.X) for tomcat do not use the System classpath
setting
by default. In a production environment I'm fine with putting my jars
in the common\lib directory but in development I want to be able
to add my source tree to the classpath tomcat uses. once I do this by
changing the setclasspath script It stops finding internal files. one
example
is creating a custom realm. I fails to find the BaseRealm file that is
in the server\lib\catalina.jar once I add that to the script it fails to
find 
other files in additional jars.

Does anyone have a solution other than having to make a new jar file every
time
I recompile?

Re: Re[2]: Tomcat redirect

[joshua wentworth]

Yeah, I figured that out a bit later. The problem seems to be that Tomcat is
just ignoring the call to /servlet/Whatever.
The situation is like this, I'm trying to get as specific as possible now.
The code looks like this:
 

And if someone clicks on that button they get a 404 and Tomcat returns the
error that it can't find /servlet/CatalogServlet. This exists without any
 stuff setup in server.xml.  The problem is that in the original
call to the original servlet we have apache redirecting the request to
http://our.server.com:8080/spike/servlet/OurServlet and when OurServlet
calls OtherServlet via the code above it tries to locate it on
http://our.server.com:8080/servlet/OtherServlet and that doesn't work. It
has to have the /spike/ in there. So... Any idea how I can do that? One of
the issues is that I can't change the code in the servlet itself (Otherwise
fixing this would be trivial).

RE: SessionMgmt: No Cookies sent - Instead only URL-Rewritting active

[Brandon Cruz]

You are right.  With IE6, cookies must be accompanied by a privacy policy,
which is a basic xml file.  If this policy is not supplied, then IE6 won't
allow tomcat to even set a session cookie.

There is a place at w3c.org where you can answer a bunch of questions and it
will generate the policy for you and tell you how to use it.

Subject: Re: SessionMgmt: No Cookies sent - Instead only URL-Rewritting

I've observed the same phenomenon.

It's just a theory, but I suspect it might have to do with Internet Explorer
6 itself. I think Microsoft quietly changed IE6's default cookie-acceptance
behavior to automatically reject all cookies from sites not meeting its
criteria for auto-acceptance. Taking a wild guess, IE6 might now
automatically reject cookies from sites accessed via IP addresses that don't
resolve to a hostname.

Another possibility: a few years ago, when anti-cookie hysteria was being
fanned by magazines eager to scare naive readers and people were disabling
cookies for stupid reasons (like thinking a "malevolent cookie" could
reformat their hard drive), Microsoft quietly introduced a special anonymous
cookie-in-all-but-name ("session id") that persisted only for the duration
of a single session (I think it even went away if you browsed to another
site or were inactive for more than an hour), but could not be disabled (so
IIS could depend upon its availability and use it to track users from page
to page within the session and match the correct IIS session variables with
the right user).  I'm not sure whether Tomcat and other servlet containers
take advantage of it (or whether they'd even be ABLE to without lying to the
browser and pretending to be IIS), but I see two likely scenarios:

1) Tomcat (and other servlet containers) can't/don't use the special
anonymous session ID, and IE6 is now denying session-cookies by default
because something is triggering the behavior (non-resolvable IP, etc.)

2) Tomcat (and other servlet containers) DO use MSIE session IDs when
available, but IE6 now denies even THAT to sites that fail to meet its
criteria for acceptablity (possibly holding sites openly running a server
other than IIS to a higher standard)

Why not put your source in the WEB-INF/classes directory of your context
or put them in any other directory, and use ant to build and have it
build the classes into that directory?

Running an external application from a Java servlet environment

[Helen Dawn Pringle]

Dear People,

I am trying to invoke Windows Media Player from within a Java Servlet environment 
using Tomcat however I can only invoke the application but I CAN'T seem to 
automatically get it to play any content. I have to physically type in the path and 
then WIndows media player will play it. Is there any way that I can not only launch 
the media player AND play the content from within there? If I can't why not? I am 
guessing that Java Servlets have only a sandbox environment involved in there!

Regards

Helen Pringle

RE: Classpath problems with Tomcat4 and RedHat 7.2

[Jose Ferrer]

Yes, CATALINA_HOME is set to /var/tomcat4

Here is my simple jsp

<%@ page language="java" %>
<%@ page import = "java.util.*"  %>
<%@ page import = "java.io.*"  %>
<%  Properties prop = System.getProperties();   %>
Java class path: <%=prop.getProperty("java.class.path")%>

<%
Properties props = new Properties();
FileInputStream fin = new FileInputStream("DBConnMgr.properties");
props.load(fin);
%>

<%=props.getProperty("admin.log")%>

The java.class.path returned is
Java class path: 
/usr/java/j2sdk1.4.0/lib/tools.jar:/var/tomcat/common/lib/:/var/tomcat4/  
bin/bootstrap.jar
Notice the missing 4 in the common/lib classpath.
It is interesting that the bootstrap.jar is listed as being in /var/tomcat4 
but common/lib is listed as being in /var/tomcat. I'm still trying to 
figure out where the classpath is set. I know how to do this when tomcat is 
started from a shell but not as a daemon.

If I place the DBConnMgr.properties file in my root directory it works. 
When I place it in /var/tomcat4/common/lib (or any other supposedly valid 
classpath) it does not.

Re[4]: Tomcat redirect

[Jacob Kjome]

Hello joshua,

Well, take a look at the form action:

action="/servlet/CatalogServlet"

This isn't even a servlet to servlet call.  This is a browser to
servlet call.  On top of that, you are telling the form to be
sumbmitted to http://our.server.com:8080/servlet/CatalogServlet

This tells Tomcat to look in the ROOT context and find a servlet
called "CatalogServlet".  However, you want to look in the "spike"
context.

Just change your action to the following:

Assuming you are at a web address that looks like:

http://our.server.com/spike/servlet/SomeServlet

action="CatalogServlet"

will be translated by the browser as a request to:

http://our.server.com/spike/servlet/CatalogServlet

or

if you don't want to count on being in the /spike/servlet path already
like above, then provide a hard path off the root of the web server:

action="/spike/servlet/CatalogServlet"

Which translates to the following no matter what your current URL is:

http://our.server.com/spike/servlet/CatalogServlet


If you are wondering how to dynamically write this link in your
servlet, just do:

req.getServletContext() + "/servlet/CatalogServlet"

That will translate to:

"/spike/servlet/CatalogServet" which is what you want.

Note, it also works if you are using the ROOT context since
req.getServletContext() will return "/" in that case.

Does that help?

Jake

Re: Running an external application from a Java servletenvironment

[Larry Meadors]

I presume you are trying to run the code on the server?
 
If so, I did it (with winamp) by creating a play list then calling
this:
 
Runtime.getRuntime().exec(mp3PlayerPath + " " +
tmp.getAbsolutePath());
 
I suspect that the WiMP has a similar type of command line that would
do the same thing.

Re: Running an external application from a Java servlet environment

[Jacob Kjome]

Hello Helen,

The media player is a client side thing.  It has no clue whatsoever
that you sent the media content via a servlet or a static file.  You
just have to make sure that when you send the content in the response
that you set the appropriate mime-type.  If the user has media player
installed *and* it is associated with that mime-type, then media
player will be automatically launched on the users machine to play the
content.

Does tomcat4 do logging cleanup

[Quinlan, William P (Bill)]

Does tomcat4 do logging cleanup, such as removing accumulated backup logs and trimming

Where may I find documentation on how this is done?  How do I configure the parameter 
that controls the amount of disk
space dedicated to this task?
Thanks,

Problems with memory

[Rich]

Hello all,

I have a fairly complex web application that appears to have a memory issue.
I've come to this conclusion by making requests to my application while
watching 'top' output. In an attempt to track this down, I made the servlet
simpler by stripping out functionality. I continued doing this until what
I'm now left with is a "Hello world" servlet. Even with this simple program,
it still appears as though I have a memory leak. Its not much, but "top"
shows an increase in memory consumption ever 5-10 requests. Finally, I just
started requesting the tomcat-docs resource ... and I get the same thing!
Again, the increase in memory usage to shows is small however the increase
does appear to be there.

Am I interpreting these results incorrectly? I am at a loss as to how to
track down a memory issue in my own servlets, if I can't start at some
baseline.

I'm running Tomcat version 4.0.3 on Linux Redhat version 6.2

Thank you,

Rich

Re: Re[4]: Tomcat redirect

Thanks, I went ahead and told the developers that they were just going to
have to fix their code to be correct. Ideally we didn't want to change the
code, we just wanted to kludge tomcat to work with the original call
(backwards compatibility issue with the code). Thanks again.

Directory access control?

[Golan]

Greetings:

I am wondering/hoping that it is possible to control HTTP directory access
for Tomcat via either the server's root web.xml or server.xml. Is this
possible with a STAND-ALONG Tomcat?

For example...

The system knows, automatically, to deny access to the ./WEB-INF/ directory.
How does it know this and is it possible to specify other "off limits"
directories?

Thanks.

Re: ?? Class Loaders, Static Initializers, Open Files ??

[Tony LaPaso]

Thank you all for the replies. The unfortunate part of this is
that my servlet runs in a shared Tomcat environment so I don't
have the luxury of putting classes/JARs wherever I want.

I *will* be able to but some code in the destroy() method to
inform the XXX class that it should close the file. I was just
wondering if there was a better way..

Yes, WEB-INF and META-INF subdirs of a tomcat context root directory are not
accessible externally (so the browser doesn't have access to any file under
these dirs). They're just accessible internally (by the server-side
application). Your applet files (.class or .jar) must be visible by the
browser, because their reference is put in JSP-generated HTML page (that is
parsed and managed by the browser itself), so you have to put them under a
subdirectory of "applications" other than WEB-INF.

Hi Kris, the jar that contains the applet and related classes *must* be
accessible by the browser. If not the browser could not load it and extract
the applet (throwing the java.io.FileNotFoundException).

Oggetto: Help with hiding resources


Hello all,

I have an application using jsps, servlets and applets runing under Tomcat
4.03 and Struts 1.0 (win2k server).
My application is located under "C:\Tomcat4\webapps\applications\" and all
jsp files are there. Some jsps launch applets through  tags.
Applets are packaged in jars located in
"C:\Tomcat4\webapps\applications\jars\". A code fragment launching applets
looks like this:
http://www.domainmame.com/applications/jars/"; or
"http://www.domainmame.com/applications/jars/myapplet.jar"; and ultimatelly
decompiled. I would like to hide the resources (jar files and everything
else that is located in subdirectiories of "\applications\". I have tried
putting the jar files in "C:\Tomcat4\webapps\applications\WEB_INF\lib\"
where all other jar files (struts.jar, etc.) are located, but then
regardless of what I used for "archive" and "codebase" parameters in
 tag I get and file not found exception in the plugin console
(java.io.FileNotFoundException:
http://www.domainmame.com/applications/WEB-INF/lib/myapplet.jar) even though
the jar file is there.

I have tried setting the following values for "archive" and "codebase"
parameters in  tag with the jar file in
"C:\Tomcat4\webapps\applications\WEB_INF\lib\":

  archive = "myapplet.jar"
  codebase = "."

  archive = "/WEB-INF/lib/myapplet.jar"
  codebase = "."

  archive = "myapplet.jar"
  codebase = "/"

  archive = "myapplet.jar"
  codebase = "/applications/WEB-INF/lib/"

None of the combinations worked. Can anyone help me with configuring these
two parameters so the Tomcat can find myapplet.jar.

Or is there a better solution to hiding resources under Tomcat.

Any help would be greatly appreciated.

Thanks

Kris

RE: manager reload not processing new security constraints

[Lawlor, Frank]

Charlie,

Your suggestion to use stop/start worked.
I still don't know if reload is supposed
to process the web.xml (would be nice if 
this was made clear), but start/stop does
the job.

Thanks,
