RE: tomcat has to be restarted every few hours (resent, mailserver errors)

[Dinu Jose]

Hi All,
I am also facing a similar problem.I need to restart the
tomcat every two hours.If the tomcat server and the database server are on
same machine,then there is no problem and it works fine .But if these two
are on different machines,then every two hours i need to restart tomcat in
order to make the application work fine.I am using tomcat3.2.2,oracle8i and
sun solaris5.8. Have anybody faced this situation before.Could somebody help
me to resolve this issue.

Thanks in Advance
Dinu.

Re: file download servlet

[simon]

I was using the path in a similar way but passing the whole URL:
e.g.
http://192.168.1.105/test1/servlet/test1/http://www.example.com/main/page1.html

This worked fine for tomcat v3.2.1 but when I upgraded to v3.2.3 the '//' got 
converted to '/'.  I realise this was for security
reasons but, out of interest, is the above URL really considered illegal or a security 
threat?

Re: The pitfalls in restarting tomcat

[Jonathan Eric Miller]

I agree that there should be a restart.sh. However,  it is possible to
restart/reload a servlet without having to stop and start Tomcat, in version
4 that is, which is due for release any day now. I think you can do it in
Tomcat 3 as well. In 4, you can mark a Context as reloadable. Then, it will
check the files when they are requested, and if the time stamp is new, then,
it will automatically reload the servlet. Also, there is a management
servlet that allows you to restart other servlets in case you don't want to
have auto-reloading on.

Nonetheless, I still think a restart.sh command would be useful.

Re: file download servlet

you could go a step further than that, and remove the query string
altogether, extracting it from the request url.  That way the end user
wouldn't even know it was being served by a servlet (well, the /servlet
might give it away, but you could change that if it mattered)...

Re: file download servlet

[Ketan Patel]

Hi,
To download file with the specific file name like song.mp3 as your
following url 
http://192.168.1.105/download/servlet/download?filename=song.mp3
changed it with following url-
http://192.168.1.105/download/servlet/download/song.mp3?filename=song.mp3
.
So while downloading the extrapath song.mp3 will be the filename.

Re: Multiple Tomcat workers (using mod_jk)

[Jan Labanowski]

I am not the developer, so I do not know... But this is what I think:
The workers are different instances of Tomcat, and can reside even on
different machines, i.e., obviously they run under different VMs
At the same time, the load balancing worker should send the request
which belong to the same session to the same worker for processing...
>From what I know, if you configure this right, the Apache talks only to
a single, load-balancing worker, and has no control over which worker
does the actuall processing, unless you mount different contexts to different
workers, but then you are in control...

But yes, there is a lack of good documentation on doing load balancing with
mod_jk, though there is plenty on mod_jserv.

Here are some excripts from someone who tried this:

Subject: Re: Tomcat and Apache on diffenet machines
Date: Fri, 25 May 2001 15:10:36 +0100

Yup this is possible 
 
and if you are using the loadbalancing module ( so you can have more
than 1
tomcat for your apache(s) to talk to) essential
 
in workers.properties you should find something like ...
 
worker.ajp12.port=8007
worker.ajp12.host=localhost
worker.ajp12.type=ajp12
worker.ajp12.lbfactor=1
 
To define another service try ...
 
worker.external_1.port=8007
worker.external_1.host=192.168.34.43
worker.external_1.type=ajp12
worker.external_1.lbfactor=1
 
You can define as many of these as you want.
 
You can then define a loadbalancer ( if you want to)
 
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp12, external_1, external_2 etc
 
then
worker.list=loadbalancer
and you have got load balancing
 
If you just want to use a single tomcat host then
worker.list=external_1
 
in your mod_jk.conf
 
JkMount /test/* loadbalancer
 
or
 
JkMount /test/* external_1

Multiple Tomcat workers (using mod_jk)

[Tony Vinayak]

Folks,

I've got a couple of quick newbie questions:
Environment: Apache 1.3.20 on Solaris 8; Tomcat 3.2 (using mod_jk); Apache
and Tomcat running on the same box.

If I configure and run multiple Tomcat workers on the same machine
(listening on different ports of course), and let's say they are all using
ajp13 connector, do all those workers run in the SAME of DIFFERENT VM ?

The reason I ask is that I've got a thread-unsafe servle that I want to
deploy implementing "SingleThreadModel" across multiple concurrent instances
of Tomcat, allowing concurrent requests to be processes. As the request gets
into Apache, using mod_rewrite I want to direct it to one of the several
Tomcat workers.

regards,
Tony

RE: file download servlet

[Tony Vinayak]

In your servlet's doGet processing, you will need to have a line of code
like:
resp.setContentType("text/plain");

Of course, for your mp3 file, it won't be text/plain, but a different
mime-type (audio/mpeg or whatever)

The server sends a header that describes the file type.

Dear Jean,

HttpSession is a height level interface built on top of cookies only. So if

Tomcat 3.2.3 : do threads I make myself count towards max_threads

[simon]

Hello everyone,

I'm using Tomcat 3.2.3 on Vine Linux 2.1.5 (basically Redhat 6.2, Japanese version)

Q: If I create a new thread in my servlet is this counted as a 'tomcat thread'?  I 
have read on the mailing list (and have
experienced first hand) that if the number of threads passes the max_threads setting 
in server.xml then tomcat 3.2.3 dies less than
gracefully.  Is this 'thread count' just the threads created by tomcat itself or does 
it include threads that I create in my
servlet?

Hope you can help,

Does anyone have any references or information on using

Are there any Java JNI wrappers for the native system calls?

Are there any higher-lever implementations to some other

Re: Destination Port for mod_jk

I've gotten around it for now my making an iptables chain that accepts

anybody has any suggestions, that'd be great.

0) Upgrade to FreeBSD 4.3 (or wait few days for upcoming 4.4 Release)

1) If possible, allways use ports !  They are ports, you know, something
is ported, changed, specific to FreeBSD

2) I'd suggest skipping JDK 1.1.8 ang go directly to 1.2.2 or 1.3/1.4 
(big difference!! see http://java.sun.com )

Here is my directory structure for testing all "Core JSP" book examples.
I gave this Application a "core" name. All dirs are relative to tomcat's
"webapps" directory, wich is /usr/local/tomcat/webapps.

[/usr/local/tomcat/webapps/]core   <-- HTMLs, JSPs
core/jsp <-- HTMLs, JSPs
core/WEB-INF   
core/WEB-INF/classes   <-- non-packaged servlets
core/WEB-INF/classes/coreservlets  <-- coreservlets's package servlets

As for your last question: use symlinks. The "core" application may
reside anywhere. Just symlink /usr/local/tomcat/webapps/core to the
place where it is.
Apache directory structure and Tomcat's one are not related at all.


http://mylocalhost/core/jsp/some.jsp
http://mylocalhost/core/servlet/SomeServletInClassesDirectory
http://mylocalhost/core/servlet/coreservlets.SomeServletFromCoreservletsPackage


have a nice day.

p.s. I am new to Java/JSP/Servlets/Beans/etc/etc too :-)  But I like it.
Coming from PHP world, it is a bit hard to get the point at once.. but..
try :-)

Just split your mind into many pieces: one for Apache, one for Tomcat,
one for this container, one for the other one..  :-)

ClassLoader error

[Marcia Perry]

Hi,
I'm running the pre-compiled binary of Tomcat 3.1 on Solaris 2.7.
If I compile my servlets with JDK1.2 and use environment variables
for JDK1.2, my servlets run fine.  However, if I compile a servlet
w/ JDK1.4 (and also change my environment vars for jdk1.4), I get
this error:
"Bad major version number" from the ClassLoader.

Any suggestions on how to get TC to load/execute servlets compiled
with jdk1.4?

Thanks

RE: Question on restarting Tomcat service

[Hoggatt Matt - mahogg]

Yes, you need that file!  When NT tries to start that it runs the following
command:

C:\path\jk_nt_service.exe Jakarta

Just put that back where it was and you're problem should be solved.  If you
want to change the path, you will probably have to delete the service and
create a new one.  That's just speculation. . .

Hi,

I have successfully configured Tomcat 3.2.3 to run as a service on my NT
machine. I copied jk_nt_service.exe to my local directory: 
C:\Project\Tomcat\win32\i386 and executed the file from the same directory.
My question is:

I stopped Tomcat service from running then deleted the
C:\Project\Tomcat\win32 folder and all of its contents. I tried to restart
Tomcat service again without this win32\i386\jk_nt_service.exe file and it
failed. I got the following error message: Error 3 The system cannot find

Destination Port for mod_jk

[Scott Jones]

Hello,

I'm setting a pair of machines, one of which is running tomcat, and the
other of which is running apache.  I am using ajp13 to connect the two
machines, and am trying to configure an iptables firewall on the apache
machine (the tomcat machine will be next).

The roadblock that I'm running into is that I don't know which ports
will be used as the destination ports on the apache machine when tomcat
replies.  The ports that I set up in server.xml and in
workers.properties are the source of my replies...

Looking at my syslog log file, I see that I'm getting information sent
to ports 32769 up through 32792 (and maybe even more, I haven't looked
through them that much yet).  An example line is included below:

Sep 12 11:42:51 web1 kernel: INT_IN DROP 7 IN=eth1
OUT=MAC=00:30:48:11:69:a8:00:b0:d0:e1:cc:0f:08:00 SRC=192.168.1.32
DST=192.168.1.21 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=TCP
SPT=8011 DPT=32794 WINDOW=5792 RES=0x00 ACK SYN URGP=0 

Where is this port configured (if it's configurable)?  Or, does anyone
know which ports I need to be leaving open?

Thanks very much for any help!

Sincerely,

Scott

example, if you
need to have users log into a specific domain (e.g. different clients

of Realms is
non-unique IDs), then you need to still force people thru a specific

Newbie - Setting environment variables??

[Joel Fowler]

I'm using a package that requires that I have a DISPLAY variable set 
Tomcat's environment.
I've attempted to export this variable before running startup.sh as well as 
including:

export DISPLAY=localhost:0.0

in a .tomcatrc file. Neither approach seems to have accomplished this.

How do I place variables in Tomcat's environment??

tomcat-users.xml reload.

[Benoit Bertrand]

   hello,

   I have got a question concerning tomcat-users.xml reloading. I am
developping a web application where an administrator can add/remove user(s)
(to contraints access to this web app). This operation add/remove the
necessary information to/from tomcat-users.xml file.
   Unfortunately, i discovered that this file is not updated until the next
startup of tomcat. This is to say that to complete the add/remove operation,
tomcat should be stopped an restarted (which is not what i intended to do).
   My question is the following: is there a way to reload the user access
from tomcat-users.xml ? If not this should say that i can not use
tomcat-users.xml to contraints access for my web app ?

   Sincerely,

   Benoit Bertrand.

Doesn't Tomcat support wildcards like *.jsp or *.html at ??

[Meinolf . Schulte-Doeinghaus]

Hi, 
I've tried to use wildcards for a webresource collection like *.jsp
to denie "guests" to access these pages but it doesn't work with tomcat
3.2.3 
Isn't that defined within the servlet specification?

Sample:


/jsp/*.jsp
/jsp/*.jsp
 

admin



Can I add a further web-resource-collection in a subdirectory of /jsp and 
give access to everyone? Like   /jsp/images/*  --> role-name = everyone
What is the "everyone" role that requires no password with tomcat 3.2.3?

Help: Tomcat 3.2.3 and Apache on FreeBSD **Java newbie**

[nbd95]

The details:

FreeBSD 4.1
Jakarta-Tomcat 3.2.3
JDK-1.1.8
Apache 1.3.20 (DSO)
mod_jk

I've been around the block with PHP, Perl, Bash, Apache, Unix, Linux,
Postfix, BIND, Netatalk, Samba, Kernels. Building, configuring, patching,
set-up, custom compiling, all no problem. I am *new* to Java.

I've installed Tomcat-Apache and it appears to work.
http://localhost/examples accessed through Apache, the Tomcat examples all
function. http://localhost:8080/ accesses the Tomcat main page, the examples
work here as well.

I have returned my configuration to the beginning, removing my muddled
attempts at setup. Currently I have this line added to my httpd.conf,

Include /usr/local/tomcat/conf/mod_jk.conf

mod_jk.conf has been changed *only* to correct the path to mod_jk.so and the
path to the mod_jk.log file. At this point Apache starts, loads mod_jk.so,
and the examples can be accessed and run successfully.

Tpp! Phooey.

My problem is I am trying to get examples of *.jsp code to work
unsuccessfully. I have example code from a book (Core JSP) that I cannot
run. Can anyone step me through creating a directory where I might store
*.jsp files for experimenting? I'm simply trying to eval JSP and explore
it's environment.

I've read the book, Core JSP, and the "Working with mod_jk" - "Tomcat-Apache
HOWTO" papers. I still don't get which *.conf files I need to modify to send
*.jsp files to Tomcat from the Apache directory structure.

I thank you for your indulgence.

I just installed Tomcat on a FreeBSD 4.1 system and it's working fine,
though I don't yet know how to use it 8^(

Two solutions,

1) Use the ports collection which works very well and will install a running
Tomcat-Apache solution. Requires FreeBSD 4.2+. This in the method I used
though I did install a new Apache using a FreeBSD layout (not included with
Apache src).

2) Follow the instructions from the Tomcat web site. Requires you have
already setup the JDK and JavaVMWrapper. I used JDK 1.1.8 and Javavmwrapper
1.1. I've done this as well and it worked also.

I would be happy to send more detail if needed.

RE: Two contexts sharing one WebApp

[Larry Isaacs]

Matt,

Congratulations on getting it to work. AFAIK, hardly
any of the modules/interceptors are written to be extensible
at the moment.  The public methods are for configuration
and interaction within the server architecture.  The
implementation, I think, is typlically private.  Using the
existing code as a starting point for a customized version
will be the norm for most modules.

Making WebXmlReader more customizable could be done, but
there probably isn't time to include it in the 3.3
release.

Cheers,
Larry

RE: Two contexts sharing one WebApp

[Matt Small]

Ok, I got it working but in doing so I found a couple of weaknesses in the
WebXmlReader class (it is difficult to extend), I think. I think that there
might be room here for improvements in tomcat, flexibility could be added
without breaking the requirements of the spec. I realize that there are
proper ways to get the behaviour I want but supporting multiple contexts
from one web-app is pretty convenient in this case.

What I wanted to do was add an attribute to my context specifying the name
of the the web-app descriptor. If the attribute is not specified then tomcat
would implicitly load web.xml.







I then wanted to sub-class WebXmlReader and provide my own implementation of
contextInit(Context ctx) that would get the descriptor file from the Context
and read that file.

This seems like it would be a pretty clean implementation to me but I could
not do it for a couple reasons:

1) I did not have the time to properly reasearch how "descriptor" attrib
would be parsed and stored in Context.java. I'm sure though that you guys
who know how it all works could implement that in a snap.

2) I had trouble sub-classing WebXmlReader. The method "processWebXmlFile()"
is package private and must be called. If it were protected I dont thing I
would have had any trouble. If anything please open up the access on this
method.

I eventually hacked up an implementation that works for me but is definately
not good. I actually just modified WebXmlReader so that it gets the Path
from the Context, builds the xml file name from the path (in my case it
assumes pub.xml because the path is /pub) and if that file exists it reads
that one, if not it reads web.xml. I then just found it easiest to rebuilt
the whole facade22.jar and updated it in lib/container.

Is this the sort of change you guys would be willing to make in Tomcat? Or
would something like this not fly because its not in the spec?

Thanks for all of your advice on this one Larry

Hi Matt,

Congratulations on getting this far.  Off the top of my head, I'm
not sure if "tomcat/classes" is supported.  I'll try to review
what methods are available to add classes rather than jars to
Tomcat 3.3's classloader hierarchy.  I suspect there is room for
improvement here.

In the meantime, the simplest way to add your class to Tomcat 3.3
is to put it in a jar and put that jar in the "tomcat/lib/container"
directory.  This will get your class into the correct classloader.

Cheers,
Larry

It works for me, and for many others.

Could you please prepare a small webapp WAR file that illustrates your
problem, and create a bug report (with this WAR as an attachment)?  We'll
need a copy of your server.xml file as well.

RE: To maintain bean session from a jsp called in a servlet?

[Larry Isaacs]

The preferred method for tracking sessions between requests is to
store a session ID in a cookie.  If you can assume that all
browsers accessing your site will have cookies enabled, then
you don't need to do anything special to have sessions work.

If you can't make that assumption, you must use 
HttpServletResponse.encodeURL() to "fix" the URL's you include
as links in the content returned to the browser.  This method
adds ";jsessionid=" to the URL if needed.
When the modified link is clicked, the URL carries the
session ID should cookies be disabled.

RE: file download servlet

[chiuming]

But how exactly does web server instruct web browser
to save the stream of bytes into a filename as 

filename on server?  

Does web server send any HTTP header like
Content-Disposition to specify the file name to save?

Since If i dont' set any HTTP headers in my servlet
but just send the bytes.  Browser will save the 

file as servlet name.

thanks again

RE: IIS Virtual hosting

[Larry Isaacs]

Hi David,

Multiple virtual hosts on IIS is something I have not found time
to try to do, yet.  However, it is something I hope to support
in Tomcat 3.3.

Tim Whittington has submitted a patch to the isapi_redirect.dll
that should be included soon.  It adds a feature where
the "isapi_redirect" dll queries its actual file name and
uses that name to read a ".properties" file from
the same directory.  If that file exists, those properties are
used.  If not, it reverts to the old behavior of getting the
"properties" file location from the registry.  This "properties"
file would specify where to get the "uriworkermap" file.

This implies that you get multiple isapi_redirector instances,
each using different settings, by having multiple copies of the
"isapi_redirector" with different names.  Each virtual host
would use the appropriately named copy.  Not elegant, but
I'm not sure there is a better way.

Cheers,
Larry

IIS with Tomcat: Change default servlet directory

[Albert]

Hi All,

I've installed Tomcat on Winnt4 with IIS4 and I've
followed the instructions in "Tomcat IIS HowTo" to let
IIS cooperate with Tomcat. It works if I set the home
directory of my Web site in IIS to d:\tomcat (for my
case, TOMCAT_HOME = d:\tomcat). I can run the servlet
examples included in Tomcat successfully. Now I decide
to change the home directory of my Web site in IIS to
another directory (for my case, new home directory =
d:\myWeb) and also put my servlet classes into another
directory e:\myServlet. However, I don't know how to
set config files to let my servlet classes be
executed. Would anyone help me with an example for my
case? Thanks in advance!!

Visual Age 3.02 and Tomcat 3.11 - Problems configuring Tomcat for my own servlets

[S.Munz]

Hi,

(I'm using VA for Java 3.02 and tomcat 3.1.1 running inside VAJ.)
I have problems running my own servlets from the VAJ workspace
without exporting it. When I start tomcat and type in the URL of my
servlet i get a message that the page is not found. (BTW: The
tomcat examples work fine).
I've already read some hints posted earlier in this mailing list and
therefore set the class path of the class that starts tomcat. It
includes all projects of my workspace.

Question 1: Do I have to mention my project in the tomcat conf. file
server.xml? If yes, do I have to set the doc base to
...\project_resources\my_project?

Question 2: Do I have to set additional classpath variables?

Has somebody had similar problems and can help me?

RE: IIS-Tomcat case insensitivity

[Randy Layman]

Perhaps a possible solution to your problem would be to create
something in IIS that on 404 would examine the URL and change the case to
what is needed, and then perform a forward?
I assume that this is possible, but I don't know how to do it.

You would need to modify the source code for Tomcat to do this.  However,
if you do, you are opening your web app to all manner of security attacks.
Therefore, this option is not supported through configuration switches or

I am looking for a way to integrate Tomcat 3.2 with an existing case IIS
application.
Unfortunately I have no control over the static HTML and many bookmarks that
have used mixed case. 

Consequently I need to make Tomcat 3.2 and the uriworkers.properties case

Any ideas ?

iis redirecting servlet requests to tomcat but not JSP requests

[Hughes, Tim]

Hi,

I have set up Tomcat on NT4.0 as a standalone and everything (servlets and
jsps) work fine if I connect directly to Tomcat.
I then set up IIS to forward requests exactly as described in the HowTo. The
result is that when I connect to IIS with a servlet request e.g.
http://localhost/examples/servlets/HelloWorldExample everything works fine
(html files are also returned without problem) but if I try to get a jsp
e.g. http://localhost/examples/jsp/dates/date.jsp I get an HTTP 500 error.
What could be the cause for this?

Any help is greatly appreciated.

6.2) and would lock up on Solaris 2.7 and 2.6.  Both systems with JDK 
1.3.1, Tomcat 3.2.3, & Apache 1.3.20.  It would eventually stall and 
require restarting.  Sometimes it would go several hours.  Sometimes it 
would lock up on the 2d or 3d access.

I never conclusively resolved where the problem was coming from but I 
have seemed to fix it.  My index.jsp was loading a session bean and 
several frames that used the bean.  From the next exceptions that were 
being thrown, I guessed there was a race condition on loading the bean 
in  JVM on Solaris.  I rewrote the application to call the session bean 
only once in the initial index.jsp and its frames.  Since then it has 
run fine--repeated new user hits and no lockups.

WebdavServlet and WEB-INF folder

[nicolas bonvin]

Is there a way to configure the org.apache.catalina.servlets.WebdavServlet
so that webdav clients can access the WEB-INF folder?
The provided "webdav" webapp doesn't display the WEB-INF folder - an
understandable security precaution, but I would like to turn it off.

thanks,

If you were to read the servlet specification
, you would find that
there is indeed such a tag, and it is even called .  You will
also find out about some request attributes that the container sets to let
your error page know what the error was.

RE: static class and JSP

[Randy Layman]

You need to import the class using <%@ page import="class name here"
%> at the top of your file.  This works like regular java imports, except
the import attribute can be comma delimited (or there can be multiple
imports, or both) and you must import all classes (the default package is
not imported for you).

static class and JSP

[JBrawner]

Upon tomcat being started, I have a servlet populate a static class with
configurations that are used by other servlets when they are invoked.  This
works great!  But, now I'd like to have my JSP's use this static class but
I'm getting the "Undefined variable or class name" error on the JSP.  How
do I tell the JSP's where this file is?  It is in the web-inf/classes
directory with my other servlets.

RE: servlet hang

[Andy Bailey]

I had problems like this in a more conventional Server/Client (Applet)
scenario.

I am not entirely certain what causes the ObjectInputStream to think it
is at EOF and didn't really
have the time to find a 'workaround'. It was actually easier to create
an RMI setup for what I wanted to acheive. Sounds daunting, it isn't
really. Needed the Java plugin in the browser to make it work (not a
problem for me, these are limited distribution, read Intranet/Mobile
client, applets.

I initially wanted to do all my communication via a servlet using a
stateful server/client setup however http based communication is NOT at
all well suited for such scenarios. If you need your servlet to perform
other duties, eg statistics etc, then it can also use RMI, means RMI is
being used as a bridge. I found that I was able to do away with the
servlet altogether in the end.

IIS Virtual hosting

[David Oxley]

Hi all,

I need to set up IIS with each virtual host routing to a different worker in
Tomcat. Each virtual host has the same web application under it and
therefore must all be the same context.

i.e. Under Apache I set up the following:
NameVirtualHost 128.100.2.23


ServerName cisweb2k
JkMount /spweb/servlet/* ajp13_1



ServerName cisweb2k2
JkMount /spweb/servlet/* ajp13_2


How is the best way to achieve the same configuration with IIS?
I think what I need is to be able to specify the host name in
uriworkermap.properties:
cisweb2k/spweb/servlet/*=ajp13_1
cisweb2k2/spweb/servlet/*=ajp13_2

Thanks.
Dave.

Not directly, however there is another Jakarta project called Ant

Tomcat won't start : java.lang.OutOfMemoryError

[Franck Routier]

Hi,

I'm trying to start Tomcat and get the following error :

Exception during startup processing
java.lang.reflect.InvocationTargetException: java.lang.OutOfMemoryError

[...]

I get this error with tomcat 3.3-b2 as well as tomcat-4.0-rc1.

My environment is :
Debian GNU Linux PowerPC
Kernel 2.4.4
JDK : Blackdown 1.3.0
Physical RAM : 386 MB

Note that Netbeans, JBuilder, Enhydra Entreprise (uses a modified Tomcat) 
and JBoss-tomcat all work well !

I guess it has something to do with the startup script or server 
configuration, but I didn't change anything from what I downloaded two days 
ago.

I tried to export TOMCAT_OPTS="-Xms128m -Xmx256m" and start, but with no 
success.

Where should I look for ??? I'm lost and quite unskilled to be true (I'm 
trying to learn, nevertheless !)

Thanks in advance,

Franck

I asked this question before, but I didn't get any
reply. I post it again in hope someone could give me
some hint.

I have a file download servlet serves web browsers.

request to file is like this
http://192.168.1.105/download/servlet/download?filename=song.mp3
 
The file on the server side is song.mp3.  But the file
got download to
browser is the servlet name instead.  :(

I heard i need to use the HTTP header
res.setHeader("Content-Disposition","attachment;
filename=\"" +
downloadFile + "\";"); 

Is Content-Disposition a standard header in HTTP spec?
 I heard i should use this whenever I don't want the
content display on browser (force Save as Dialog box)

Why everytime I download a file from the web server
like song.mp3.
there is no such HTTP header from web server? -->
Content-Disposition  

I think web server is just like a download servlet. It
sends raw bytes to web browser. After browser get the
bytes, It will not konw what name the file should save
as.  Web server must send some kind of HTTP header to
tell web browser what file name the file is saved as.
right?

How exactly is web server instruct web browser to pop
up Save as Dialog box (on unknown mime type) and save
the file with name = filename on server?  Does web
server use any special HTTP Header (like
Content-Disposition)
