Updated WebApp Tutorial

[Oscar Carrillo]

Hi,

Some of you may know my site:

HOWTO: Installing Web Services with
  Linux / Tomcat / Apache / Struts / Postgresql / Openssl / JDBC

I've worked on it a lot and have added many features, including

-JDBC/JNDI configuration w/DBCP-commons Pool

-build scripts for everything
-all the configuration files
-Virtual Host configuration
-A Struts-based Database Test Web App

I am having to move the site, and am now hosting this site here:
http://www.linuxjava.net/howto/webapp/

I'm including my README file for people's perusal. Please visit the site
for more info.


README
--
These files can all be downloaded with the one link:
-webapp_files.tar

I recommend doing things in this order.

Install Java
-java_install.sh

Install Ant
-ant_install.sh

Install OpenSSL. It needs to be installed before Apache.
-openssl_install.sh

Install Apache. Pretty straight-forward. Builds a few modules, not all or 
most, just fairly common ones. Add
 more modules if you want them built here.
-http_install.sh

Install Tomcat4
-tomcat_setup_user.sh
-tomcat4_install.sh

Install Mod_JK
-modjk_install.sh

Install Postgres
Read these install script. It needs to remove the bison RPM first, but it 
is commented out, cause I don't wa
nt someone to do something to their system that they don't intend. Install 
in the listed order.
-bison_install.sh
-postgres_setup_user.sh
-postgres_install.sh

Install PgAccess
-pgaccess_install.sh
-pgaccess #Put this in "/usr/local/bin/" for easy access

Sample Database
#Import the testdb.psql into your Postgres DB. This is for the Test DB 
Struts Web App.
-testdb.psql

Configuration Scripts:
Apache
-httpd.conf
-ssl.conf

Tomcat
-workers.properties
-server.xml

Daemon Scripts for Apache, Tomcat, and Postgres
-httpd
-tomcatd
-postgresqld

Struts Web App
#Extract and put in /usr/local/tomcat/webapps
-strutsdb_webapp.tar.bz2

Once everything is running, you should be able to test the webapp by going to:
http://www.myhost.mydomain/mydomain_public/

It will also be available here:
http://www.myhost.mydomain:8080/mydomain_public/

There is also a JSP file called "showJNDI.jsp" that will give you some
info about your setup. Delete that file for anything in production as it
will display your database configuration.

Please visit the site and any feedback is appreciated.

then check out

This should explain a few things.

OutputStreams, Writers and Sitemesh

[Scott Farquhar]

Guys,

I've searched the mail archive, but couldn't find anything there - so
please feel freee to point me there if this has already been answered.

Sitemesh is a page decoration framework that works on all application
servers, and allows you to decorate your HTML pages.

The way that it works is that the page is captured in a buffer, then
passed to a 'decorator', which does the decoration (using the original
content as input).

More information can be found here:

  http://www.opensymphony.com/sitemesh/

The problem comes when choosing to use getOutputStream() or getWriter()
to write out the content.  This is because you cannot call both in one
request.

My current method of doing this involves logging which of these is used
by the server, and then using that to print out using either streams or
writers.

However, in Tomcat 4.x and later, it seems that getOutputStream() is used
for serving static resources, and getWriter() is used to serve JSPs.

This means that if I buffer up static content (using a
PageResponseWrapper), then I can't then access a JSP using the same
request.  I guess that this will also affect anyone redispatching to a
JSP after accessing a static resource.

So - can anyone point me to a config somewhere that I can tell Tomcat to
use Writers for everything?  Or some other workaround?

If I haven't been clear above - please let me know.

Cheers,
Scott

Hi,
   I was told that the .class files must be put into a package in order for
the tomcat to run it.

My directory structure is as follows,

%TOMCAT HOME %/webapps/sampleapp/WEB-INF/classes
/WEB-INF/lib
/WEB-INF/sourcefiles
/WEB-INF/web.xml
In the classes directory I have make something like this
/classes/package/structure/HelloServlet.class(This is my servlet file),

Now I have changed/made the web.xml in MY WEB-INF directory and have added
this

Hope that it is right so far,

I dont know how to change the %TOMCAT_HOME%/conf/server.xml,do we have to
change anything here??, this is what I have written in the server.xml file.

I believe the default maxperm size for sun jvm is 64MB. I ran into the
same problem, when spawning additional threads, and too increased
the maxperm to 256MB. that allows me to spawn up to 3,000 threads.
I prefer to spawn all the threads at startup rather then have
tomcat spawn threads as it needs them.

my heap is set to 800MB for tomcat. the systems have between
2GB and 3GB of ram each.

been running for ages without any problems. never had an out
of memory message from tomcat(with the exceptions of when
I was testing in a test enviornment with thread settings)

running tomcat 4.0.6. Tried going to 4.1.27 but behavior
was significantly worse than with 4.0.6 for the stuff I am
using it with. running sun java 1.3_9 or something.

have never run out of heap either. still looking for
further tips/docs on how to optimize thread usage
further.

And the result was... what?

The compiler errors can be interpreted in only one way: the 
servlet-api is _not_ in your classlath. Hence there can be only one 
cause of the problem: you are not adding them correctly.
Thsi is clearly a shell issue.

/** tomcat.bat */

set classpath=;E/tomcat/tomcat-5/common/lib/servlet-api.jar
set classpath=;E/tomcat/tomcat-5/common/lib/jsp-api.jar
/** tomcat.bat */
I see three issues here: for one I don't know what that leading ; is 
about. If it's not a problem, it is definitively not necessary. 
Secondly, I am not sure if you can use forward slashes in the 
classpath on Windose machines. And either way, you are missing a : as 
in E: at the beginning.

Re: deploying parameters using catalina.ant

[Barry Kimelman]

 I myself was just recently able to successfully install application into Tomcat 5.0.16 using the ANT utility.
 
1st you need to properly setup your build.xml file (a sample can be obtained from the Tomcat web-site).
 
Then you need to modify the sample build.xml file to suit your needs.
    * modify the "" description to describe your application
    * modify the  descriptions to suit your application and Tomcat environment :
   eg. set a value for "app.name" , "app.version" , "catalina.home"
 
I found that I also had to modify the value for WAR file description on the "install" target description
in order for the "install" to work properly. For my case when I changed the WAR description to
   war=file://${dist.home}/${app.name}-${app.version}.war
 
I was successfully able to execute an install.
 
Also you should define a "build.properties" file in your home directory that at the very least defines values for the properties :
 
  manager.username
  manager.password
  manager.url
 
You should also modify the "tomcat-users.xml" file in the "conf" directory og your Tomcat installation.
You should define "roles" for "admin" and "manager".
You should also define a "user" that has the "admin" and "manager" roles assigned to him/her.
 
 After all this you should be able to run the "ant install" command to deploy your application.
 
I hope all this helps.

Subject: deploying parameters using catalina.ant
 
hi,
is there anybody out there that can help me on this subject. This is my 3rd
message. Am asking something wrong?
 
I am trying to use the command org.apache.catalina.ant.DeployTask in ANT to
deploy an application into TomCat using a context xml file. It seems it is
mandatory to issue the path parameter but with a context xml file that
should not be necessary.
 
I looked on the Tomcat site and I could not find anything on this topic. Can
anyone help me?
Where can I find information about the catalina-ant.jar?
 
 
my best regards,

writing a file from a servlet

[Jerry Ford]

From a servlet implemented in
tomcat/webapps/myWebapp/WEB-INF/classes/my/package/myWebapp.class, I am
trying to write a config file to the directory myWebapp/conf.   The conf
directory does exist; and there are no permissions issues---I can write
the file to the conf directory from the servlet if I hardcode the full
path.
The following code works:

FileWriter fwrite;

try
{
   fwrite = new
FileWriter("/usr/local/webserver/tomcat/webapps/myWebapp/conf/" +
project + ".conf");
 // ...etc.
}
catch(IOException e)
{
   // ... etc.
}
But if I change the path in fwrite = new FileWriter() to
../../../../conf/ (making it relative to the class file) or to
/myWebapp/conf/ (relative to tomcat's servlets root; with or without the
leading /) or to conf/ (relative to the myWebapp directory, which is the
docBase declared in the context element in server.xml), I get a
FileNotFound (No such file or directory) exception.
How do I make the path relative to the servlet, so I don't have to hard
code the path?
The app won't be deployed on a public web server, so writing a file to
the server is not a problem, though I would like to have some
flexibility about where things get deployed---may end up on a Windows
machine, may stay on the Linux box.  But I want to make that decision
external to the code.
Thanks.

apache + tomcat virtual hostnames

[Dean A. Hoover]

I am using apache 2 and tomcat 4.1 connected
with mod_jk. I have multiple virtual named
hosts in the httpd.conf file, such as:

  ServerName www.myserver.com
  ServerAlias myserver.com
  ...
set up so that apache serves up the static
content, and tomcat will handle the servlet
stuff. In my server.xml file I set the attribute
"name" to "www.myserver.com" in the Host tagset.
This works fine if I hit http://www.myserver.com
but not for http://myserver.com. Apache handles
both the same, but not tomcat. Is there something
like ServerAlias in tomcat?

Problem "reloading" Tomcat 5.0.16 application

[Barry Kimelman]

My system is Linux Redhat 9.
I am running Tomcat 5.0.16 from a binary distribution.
 
I can successfully compile and install my application.
The JSP page works fine.
 
However, when I make a change to the Java class used by the
Bean referenced in the JSP file, then issue a
"ant reload" command (which succeeds) and again execute my
tomcat application, I get the output from the old version of the application.
 
I resorted to "undeploying", recompiling and installing to get Tomcat to run my
updated code.
 
How can I get Tomcat to recognize the changes I make to my own personal
class files ?

You need both JARs in the classpath. Try:
set
CLASSPATH=E:\tomcat\tomcat-5\common\lib\servlet-api.jar;E:\tomcat\tomcat
-5\common\lib\jsp-api.jar
javac -classpath .;%CLASSPATH% *.java

writing a file from a servlet

[Jerry Ford]

I want to write a config file from a servlet implemented in 
/usr/local/webserver/tomcat/webapps/myWebapp/WEB-INF/classes/my/package/myWebapp.class, 
to a myWebapp/conf directory.  The directory exists, and there are no 
permissions issues---I can write the config file if I hardcode a full 
path to the file.

The following works:

FileWriter fwrite;

try
{
  fwrite = new File 
Writer("/usr/local/webserver/tomcat/webapps/myWebapp/conf/" + project + 
".conf");
  // ...etc.
}
catch(IOException e)
{
  // ...etc.
}

But if I change the path in the new FileWriter statement to any of the 
following, it does not work:

  /myWebapps/conf (relative to tomcat's servlets root)
  conf/ (relative to the docBase declared in the webapp's context)
  ../../../../conf (relative to the class file)
I get a FileNotFound...(No such file or directory) exception.

What does tomcat consider to be the relative path to the myWebapp/conf 
directory?  relative to what?

BTW, this is a private, internal app that won't be deployed in a public 
website, so there are no concerns about writing files to the server's 
disk.  But I want to reserve the option of deploying to a Windows 
machine or keeping it on the Linux box, and I don't want to be tied to a 
specific directory location on either box. 

Thanks.

RE: verbose gc

[Papillon]

A good article : http://java.sun.com/docs/hotspot/gc1.4.2/ (Java's Sun site)

Memory reserved by Tomcat via JVM is cut in three groups (more in
reality...) :
- Immortal
- New object
- Old Object

Imaging you're reserved 512Mo for Tomcat.
If you don't specify dispatch of the memory (at the Tomcat startup) you will
be have the following (it's a funny example ^^ and certainly impossible in
reality):
- Immortal 64Mo
- New object 224 Mo
- Old Object 224 Mo 
If your application need to create a lot of immortals Tomcat will crash
fastly than if you're are specifying more memory for immortal.

Another funny dispatching :
- Immortal 224Mo
- New object 64 Mo
- Old Object 224 Mo 
If your application need to create a lot of new objects, Tomcat will crash
if garbace collector take his time to do his job.

leakim

As I said in my post, we would get the OutOfMemoryError about every 24
hours.  I tried setting MaxPermSize to 256MB (haven't been able to determine
the default value for Sun's JVM, but it's 64MB for HP's JVM).
 This sets the size of the permanent generation, into which longer-lived
objects and class definitions are loaded (we have over 3500 classes over
multiple web apps).

I wasn't going to say anything to this list without being more certain, but
Tomcat has been running with no problems since Friday afternoon (47 hours as

writing a file from a servlet

[Jerry Ford]

From a servlet implemented in 
tomcat/webapps/myWebapp/WEB-INF/classes/my/package/myWebapp.class, I am 
trying to write a config file to the directory myWebapp/conf.   The conf 
directory does exist; and there are no permissions issues---I can write 
the file to the conf directory from the servlet if I hardcode the full path.

The following code works:

FileWriter fwrite;

try
{
   fwrite = new 
FileWriter("/usr/local/webserver/tomcat/webapps/myWebapp/conf/" + 
project + ".conf");
 // ...etc.
}
catch(IOException e)
{
   // ... etc.
}

But if I change the path in fwrite = new FileWriter() to 
../../../../conf/ (making it relative to the class file) or to 
/myWebapp/conf/ (relative to tomcat's servlets root; with or without the 
leading /) or to conf/ (relative to the myWebapp directory, which is the 
docBase declared in the context element in server.xml), I get a 
FileNotFound (No such file or directory) exception.

How do I make the path relative to the servlet, so I don't have to hard 
code the path?

The app won't be deployed on a public web server, so writing a file to 
the server is not a problem, though I would like to have some 
flexibility about where things get deployed---may end up on a Windows 
machine, may stay on the Linux box.  But I want to make that decision 
external to the code.

Thanks.

Jerry

Tomcat / WebSphere Performance

[Pete Stokes]

Following up from my earlier post re Tomcat performance on different 
platforms, I have 3rd party results on comparing Tomcat and WebSphere on 
different platforms for their app, obviously I don't have intricate 
details about this test.

   Tomcat  WAS Win 2K   WAS iSeries
Overall Average Response time  873ms  680ms22206ms
Overall Trans Average Response 1610ms 1200ms  -
How does this compare to people's experiences, speed comparison, etc as 
per same application in different appservers / os's ?

(Noting WAS=WebSphere app server 4.0.7), Tomcat *probably* 4.1.29. JDK 
for Tomcat unknown.

Any comments would be greatly useful.

Pete.

Re: ServletFilter on j_security_check

Frank,
if you develop a JAAS login module, you can get it to do pretty much 
anything you want, apart from having instant access to that user's 
session. You could write the login attempts to a database for instance.

Re: context configuration file being overwritten

[QM]

: (I'm trying to place as little
: as possible in the tomcat directory structure, to ease upgrade issues
: and such.)

Always a good idea.

Search the Tomcat website for "instance" or "CATALINA_HOME and
CATALINA_BASE."  (I don't have the exact URL on me.)  Using these latter
two environment variables, you can setup a sort of mini-Tomcat that has its
own conf/ and webapps/ dirs, but refers to the main Tomcat install for the
server's jar files.

Combine that with a symlink to the main Tomcat dir (e.g. tomcat ->
tomcat-5.0.18) and upgrades within the same major version are a snap.

ymmv but this works quite well for me.

About_tomcat5_manager_and_status_application

[Ingmars Rubenis]

Hello list!

I hwould like to install tomcat5 manager and status applications in
tomcat4. I have built tomcat5 from source, so I have created also
manager under server/webapps/manager and status
I have copied them to tomcat4 (the same directory), but they do not work.
What libraries should I copy to tomcat4?
How to do this?
Is it possible?
May be I should build tomcat4 from source + replace existing manager
applications in the source code?
Did anybody do that before?

Thanks in advance!

Tomcat 5.0.18 : Bad Cookie Names, the return ?

[Papillon]

I've installed Tomcat 5.0.18 (binary release) and J2SE v 1.4.2_02 on a
windows server 2000 OS.

When Tomcat receive a request (or respond ?) I have pratically each time
this type of error :

23 janv. 2004 07:12:22 org.apache.coyote.tomcat5.CoyoteAdapter parseCookies
GRAVE: Bad Cookie Name: expires /Value: Fri
java.lang.IllegalArgumentException: Le nom de cookie "expires" est un

java.lang.IllegalArgumentException: Le nom de cookie "path" est un "token"
rÚservÚ
at javax.servlet.http.Cookie.(Cookie.java:185)

at java.lang.Thread.run(Thread.java:534)

I've undestand that "path","expire","domain",etc are reserved names for
cookies. All run fine with the same classes on an "oldest" tomcat
version(3.3 who seems to have and similary corrected bug and or a tomcat
4.0.x) or when I copy the complete context (Tomcat 5 rep and Java rep) on
anothers machines (windows 2000 pro or Mac OS X).

A difference between the server and the computers : The server is behind
a firewall and have two adress. All accesses are done by the WAN adress
because using NAT.

thanks for any informations, any help, any idea ;)

Re: response.sendRedirect problem in Tomcat 5.0.18

[Ben Souther]

You'll need to structure your code so that you either write to the out stream 
or perform a sendRedirect.  There has never been a version of Tomcat that 
would allow otherwise.  This is the same in PHP, ASP, and I imagine any other 
web scripting language.

A sendRedirect does nothing more than send back a bodyless header with a 
"Location: url"  parameter.

You can't send a header once you've started writing to the body of the 
message.  You also can't write to the body after sending a redirect (which is 
why you need to add a "return" statement just after the redirect).

Re: Load Balancing Problem...Urgent

[Kok Wei, Koh]

Hi Nicholas,

It is great to see undergraduates students (especially from Malaysia), 
using Tomcat in their projects ;-) High five dude!

Ok first of all, if you're building a web application you may want to 
consider placing Apache 1.3.x in front of your Tomcat instance, to serve 
a all static contents such as html/images and proxy all tomcat related 
stuffs to the Tomcat instances.

Why not go with the latest:-
* apache 1.3.29
* tomcat 4.1.29
* and the mod_jk connector
You may find a very good tutorial on how to setup load balanced Tomcat 
servers at the following URL:-

http://www.ubeans.com/tomcat/index.html

To answer your question...


how can I send the request from load balancer connector to the connector
in that selected server?
After the selected server has finished the process, how can the server 
send back the response to load balancer and then the load balancer sends 
back to user?


An example of a complete flow of a request to a web application eg: 
http://www.xxx.com/myapp/start.do is ...

User -> Apache -> Tomcat -> Apache -> User

The way Apache determines if a particular request is to be proxied to 
Tomcar, is via the JkMount directive in the httpd.conf, see below:

JkMount /myapp/* loadbalancer

where "loadbalancer" is a worker of type "lb".

Please go through the above URL to find out more.
Good luck!

Hi,

I'm an undergraduate student from Malaysia. I'm using Tomcat 4.1.27 to
do a load balancing system. This system consists of several tomcat
servers and one of them will be the load balancer. When a user accesses
a url page, the load balancer will select a server to response to that
request. The problem that I faced now is I don't know how to make the
selected server to process the request from user browser. As I know the
tomcat connector will assign the socket to processor to process it. So
how can I send the request from load balancer connector to the connector
in that selected server? What should I send (socket? Input stream? Or
the request line? How to get these?)?After the selected server has
finished the process, how can the server send back the response to load
balancer and then the load balancer sends back to user? Can anyone help
me on this? Or is there any one has done this before? Can someone show
me the sample code for solving this problem? It's urgent. Your help is
appreciated.
Thanks,
Nicholas Tham
