RE: servlet help

[Cox, Charlie]

You need to tell Apache about your user directories.

Try this location to send anything starting with ~ to tomcat.


JkUriSet worker ajp13:localhost:8009

Claudia,

Are you using mod_jk with Apache and Tomcat?
You should be able to configure in Apache's httpd.conf
to forward particular url patterns to your Tomcat(s') worker(s).

Something like:

JkMount /yourapp/* yourworker

More details are in mod_jk documentation. I do not think that there is a
way 
to forward only servlet calls, as you can not be sure from the URL.
Usually, 
your URL/URI will have some servlet app. specific context which will
help 
you.

Configure the tomcat "web.xml" file in your tomcat's "conf" directory.
You only need to do this if you are going to write servlets. After doing
this, you can put all your servlets into the subdirectory
"WEB-INF/classes" of your webapp directory. And you can access those
servlets with a URL like:
 Uncomment the servlet element tags with the servlet-name of invoker
(just search for invoker).

invoker

Uncomment the servlet-mapping element tags with the servlet-name of
invoker.

Configurando Apache + Jakarta-TOMCAT + Connector MOD_JKConfigurando
Apache + Jakarta-TOMCAT + Connector MOD_JKHi... follow down the
"mini-howto" (Unfortunely I write in portuguese so I have to make a
translation...) I will work on it to translante and correct some
issues... perhaps even in portuguese he can help you

When I finish the translation I post to you again... (if you need any
help to especific parts mail me!)


Configurando Apache + Jakarta-TOMCAT + Connector MOD_JK
Por: David da Guia Carvalho
Data: 09-09-2004


Consideramos que o leitor possua o seguinte ambiente:
Apache 1.3 ou 2.0; (+DEVEL) + APXS;
J2SDK 1.4;
Jakarta-Tomcat 5.0;
GCC, G++ e DEVEL (LIBS e HEADERS);


Conveção do tutorial:
Letras em Itálico são utilizadas para comandos de Shell;
Letras em courier são utilizadas em conteúdo de arquivos;


Este método foi utilizado repetidamente em DEBIAN 3.0 e Conectiva 10
(Redhat like).
(ambos atualizados na data (09-09-2004)).


APACHE:


A instalação do Apache padrão da distribuição:


Debian: Server version Apache/1.3.26 (Unix) Debian GNU/Linux
nenhuma modificação.


Conectiva: Server Apache/2.0.49
(A única modificação feito foi no arquivo /etc/apache/conf/httpd.conf em
DocummentRoot por motivos de padronização.)
De:
DocumentRoot=/srv/www/default/html
Para:
DocumentRoot=/var/www


( ESTA MODIFICAÇÃO NÃO INFLUENCIA NO FUNCIONAMENTO DO APACHE + TOMCAT )


O JSDK e JAKARTA-TOMCAT:


Em ambas as distribuições instalamos JSDK e TOMCAT em "/opt".
No arquivo "/etc/profile" foram colocadas as seguintes variáveis que
indicam onde estas aplicações foram instaladas segue abaixo um exemplo:


JAVA_HOME=/opt/j2sdk1.4.2_05
JRE_HOME=/opt/j2sdk1.4.2_05/jre
TOMCAT_HOME=/opt/jakarta-tomcat-5.0.27
export JAVA_HOME
export JRE_HOME
export TOMCAT


Os COMPILADORES:


GCC, G++, LIBS e DEVELS foram instalados segundo o padrão da
distribuição (instalação via apt-get)


Introdução:


Onde obter o arquivo?
Baixe o arquivo: jakarta-tomcat-connectors-jk-1.2.6.src.tar.gz

(http://archieve.apache.org/dist/jakarta/tomcat-connectors/jk/source/jakarta-tomcat-connectors-jk-1.2.6-src.tar.gv)


Instalação:


Descompacte-o em uma pasta de sua escolha (no nosso exemplo utilizaremos
"/usr/src")


#>tar -zxvf jakarta-tomcat-connectors-jk-1.2.6-src.tar.gz


Entre na pasta que foi criada.


#>cd /usr/src/jakarta-tomcat-connectors-jk-1.2.6-src/jk/native


dentrodo diretorio inicie os preparos para a compilação:


#>./configure -with-apxs=/usr/sbin/apxs


(
Caso necessario o diretorio do apxs pode ser localizado com o comando:
#>locate apxs


Caso nunca tenha utilizado o comando "locate" atualize suas bases de
dadods com o comando:
#>updatedb
)


Após conseguir executar o configure com sucesso execute o comando
"make":


#>make 


após o comando make copie o arquivo gerado para o diretorio de módulos
do apache (isso varia de distribuição).




PARA DEBIAN 3.0:


#cp
/usr/src/jakarta-tomcat-connectors/jk/native/apache-1.3/mod_jk.so.0.0.0
/usr/lib/apache/1.3/mod_jk.so


PARA CONECTIVA 10:
#cp /usr/src/jakarta-tomcat-connectors/jk/native/apache-2.0/mod_jk.so
/usr/lib/apache/modules


Configurando o Apache:


No diretorio "conf" (para Debian: /etc/apache para Conectiva:
/etc/apache/conf/) do apache, edite o arquivo httpd.conf


Na seção "LoadModule" adicione as seguintes linhas:


PARA DEBIAN:


##

LoadModule jk_module /usr/lib/apache/1.3/mod_jk.so

Oki doki,
I got my servlets to work from tomcat using port 8080
(http://myserver:8080/~myacct/servlet/myservlet), but I still do not
know how to make apache recognize my servlets and send them to tomcat. I

this, you can put all your servlets into the subdirectory
"WEB-INF/classes" of your webapp directory. And you can access those
servlets with a URL like:
 Uncomment the servlet element tags with the servlet-name of invoker
(just search for invoker). 

invoker

  org.apache.catalina.servlets.InvokerServlet


debug
0

2


Uncomment the servlet-mapping element tags with the servlet-name of
invoker. 


invoker
/servlet/*

I am running tomcat5.5.4, apache2.0.52 and jk2.
1)I an run my jsp's and servlets from root. I have configured tomcat to
run my jsp's from the homedirs, but I do not know how to configure
tomcat to run servlets from the homedirs.

I can run my jsp's like this: http://myserver/~myhomedir/myfile.jsp or
http://myserver:8080/~myhomedir/myfile.jsp
Either way it works fine.
What do I need to add so that my servlets run from my homedirs as well??

These are my configuration files:

/usr/local/apache/workers2.properties

info=Ajp13 forwarding over socket
tomcatId=localhost:8009
 

#define the worker
[ajp13:localhost:8009]
channel=channel.socket:localhost:8009
`
# Map the Tomcat examples webapp to the Web server uri space
#[uri:/jkstatus/*]
#group=status:status
 

 

# Uri mapping
[uri:/jsp-examples/*]
 

[uri:spark.iss.utep.edu/*.jsp]
group=ajp13:localhost:8009
 


I added the following in my httpd.conf also:


JkUriSet worker ajp13:localhost:8009



(Before I would just add the lines below in my httpd.conf, and jsp's and
servlets would work!
JkMount /*.jsp ajp13
JkMount /*/servlet/ ajp13)


Also, I have the following in my server.xml file to run my jsp's from my
homedirs:

You need to have a  element in your web.xml file defining what
class MessageServlet1 is, e.g.

  MessageServlet1
  com.mycompany.SomeServlet


It's preferable to put this servlet element before the servlet-mapping
one ;)

For me when you close the browser the session is invalidated...

RE: Servlet help

[Sandra Patricia Hunter]

Okay. Thanks, John.

Any idea why nothing else will run after I run a servlet? Tomcat continues
to refer to the servlet files, which are not part of the JSP. I can't even
run a simple html page. It is like the servlet takes over, but where and
how?
The work folder remains empty.
See earlier in this thread for logs and error messages.

Once you have compiled the new servlet either jar it up or copy it 
directly
to your WEB-INF/classes, if you jar'd it then copy the jar to WEB- 
INF/lib.
Now within moments your servlet should be available unless you have:
	-turned servlet reloading off
	-have not made an entry for the servlet in your web.xml
If you have not then delete the subdirectories within your "work" 
directory,
as this will cause tomcat to regenerate all the webapp files thus 
providing
your users with the most current version.

hope that helps...

This seems like a silly question: when I make changes in my servlet what 
do I have to do to load the new file?

I have tried just saving it. I have tried restarting Tomcat. I have tried
recompiling the file. I have tried recompiling while Tomcat was shutdown 
and
while Tomcat was running. I have tried restarting the machine. Only
restarting the machine seems to work. Comments? Suggestions? Ridicule?

RE: Servlet help

[Sandra Patricia Hunter]

Thanks Yoav.

Now I know what it is for. 

Any ideas why I am having problems starting up a JSP after I have run a
servlet? Tomcat seems to continue referring to the servlet information even
when it has been stopped and started and I have even rebooted. It's like the
servlet takes over and the JSP is lost. 

I have included log files and so on in another message with this same title.

Howdy,

>Just as an aside: what is the purpose of the work folder?

To hold temporary tomcat work products, e.g. the compiled JSP servlets.
Tomcat uses this space as it sees fit, and tomcat is responsible for the

freshness / dirtiness (in cache terms) of the contents of the work
directories, as long as you follow standard deployment / reloading 
procedures for your web applications.

If you have cause to belive tomcat is serving old contents, e.g. an old
version of a JSP, one thing to try is stop tomcat and clean out the work
directory.

John:
Here is the error message when I attempt to run a JSP after running a
servlet:
javax.servlet.ServletException: Error allocating a servlet instance
at
org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:659)

When I run my JSP this is the root cause of error:
java.lang.NoClassDefFoundError: idcard/PasswordBuilder (wrong name:
PasswordBuilder)
This refers to a file that I use with my SERVLET not JSP.

I have checked that reload is set to true and that everything is included in
the appropriate xml files (context path in server.xml, servlet info in
web.xml).

Currently the work folder is empty.

RE: Servlet help

[Sandra Patricia Hunter]

Thanks Paul.
I have checked that reloading is set to true and there is an entry for my
servlet (it wouldn't run otherwise would it?) in my web.xml file.
Just as an aside: what is the purpose of the work folder?

Once you have compiled the new servlet either jar it up or copy it directly
to your WEB-INF/classes, if you jar'd it then copy the jar to WEB-INF/lib.
Now within moments your servlet should be available unless you have:
- turned servlet reloading off
- have not made an entry for the servlet in your web.xml
If you have not then delete the subdirectories within your "work" directory,
as this will cause tomcat to regenerate all the webapp files thus providing
your users with the most current version.

hope that helps...

This seems like a silly question: 
when I make changes in my servlet what do I have to do to load the new file?

I have tried just saving it. I have tried restarting Tomcat. I have tried
recompiling the file. I have tried recompiling while Tomcat was shutdown and
while Tomcat was running. I have tried restarting the machine. Only
restarting the machine seems to work. Comments? Suggestions? Ridicule?

Sandra,

if you are planning to do the changes often you are probably better off 
if you set reloadable parameter to true in server.xml file, 
(http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/context.html) 
however, setting it to reloadable means that you should accept that it 
will eat up some of your CPU time as well (not a significant one, but 
it's there).. otherwise, compiling your file, and restarting tomcat 
should suffice...

RE: Servlet help

[jsp]

Is tomcat being run as a service? If so you have to restart it there and
sometimes I also have to go to the command line c:\tomcat\bin\shutdown
... c:\tomcat\bin\startup for it to take. If your using the newer
versions of tomcat it doesn't seem to work any other way.

...and I'm an idiot, because the SQL statement doesn't filter by them, so
it's quite inconsequential, really. :)

rs = stmt.executeQuery("SELECT empno from db2admin.employee");

Re: DB2 and servlet ??? Help !!!

[Michael Locasto]

Hi,

Assuming this is the SQL you want to submit:

>
> try{
> stmt = con.createStatement();
> rs = stmt.executeQuery("SELECT empno
from
> db2admin.employee");

shouldn't it be

if( rs.next() ){

do{
  count++;
  out.println( " empno is "+rs.getString( 1 ) );

}while( rs.next() );

}

or something along those lines? (rather than the !rs.next() )

>
>  try{
>  if(!rs.next())
>{
>count = count +1;
>  String a = rs.getString(1);
>
>out.println(" empno is " + a );

RE: DB2 and servlet ??? Help !!!

[Wagoner, Mark]

I think you are attempting to output the value if there is nothing in the
result set.

> if(!rs.next())

The .next() method will return true if it was able to fetch a row.  You are
saying, "if there is no row then..."

RE: DB2 and servlet ??? Help !!!

[Turner, John]

Is "firstnme" the name of your column?  Or should it be "firstname"?  If
that's an error, there should be a SQLException thrown, but I don't know the
behavior fo DB2...it may just be that you get null back.  In any case,
besides printing a stack trace, I would output something to the browser on a
SQLException just so you can see what's going on.

Hello everyone...

I am trying to connect the run a simple servlet to retrieve the
query results from DB2 database.

1. Before writing a servlet, I wrote a simple java file and was successful
in retrieving the
contents from DB2 UDB.

2. Then I just converted the same JAVA file into servlet by adding Servlet
API and syntax in it.
3. It compiles fine.
4. Then from a web page I try to pass one parameter to my servlet.
5. The servlet doesnot retrieve any records from the database which
initially it was bringing
when I wrote simple java file.

Code of my servlet is as:
--
import java.sql.*;
import java.lang.*;
import java.io.*;

public class Ndb2Tomcat{

   public static void main(String args[]) {


  try{
 Class.forName("COM.ibm.db2.jdbc.net.DB2Driver");
 }
 catch( ClassNotFoundException e2)
 {
  System.out.println("\nJDBC Driver class not found exception");
 }
 catch( Exception e)
 {
   System.out.println("\nDriver class not found exception");

}
try{
   Connection con = null;
  String url = "jdbc:db2://100.3.13.34/SAMPLE";
   con = DriverManager.getConnection(url,"db2admin", "db2pwd");

// retrieve data from the database
   System.out.println("Retrieve some data from the database...");

   Statement stmt = con.createStatement();
   ResultSet rs = stmt.executeQuery("SELECT * from db2admin.employee
order by firstnme");

   System.out.println("Received results:");

   while (rs.next())
   {
  String a = rs.getString(1);
  String str = rs.getString(2);
  System.out.print(" empno= " + a);
  System.out.print(" firstname= " + str);
  System.out.print("\n");
   }
   rs.close();
  stmt.close();
   con.close();
 }
 catch (SQLException e1)
 {
  e1.printStackTrace();
 }

   }

Have a look at this document

It should answer your question.

Re: Servlet help needed

[Noel E. Lecaros]

Hi, Ante

You actually don't need to edit anything in server.xml if your app uses
default settings.  Just drop your app's directory tree into the webapp
subdir and start Tomcat.  Which web.xml file did you make changes in
anyway?  You're not supposed to edit the web.xml in the conf subdir!

Hope this helps.

Regards,
Noel Lecaros

BTW, just a friendly reminder.  Please don't post in HTML.  Not everyone
on this list uses an HTML-enabled mail reader.

Servlet help needed

[Ante Sabo]

 
I cannot deploy my servlet application to run by 
Tomcat. I editet server.xml and web.xml files as described in documentation to 
set up my contextes, but all I got on my screen is Tomcat error message:
 
Mapping context with unregisterred servlet 

 
 
What this message is meaning to me. I beleive I 
made everything in script files needed to register my sevlet, and also 
registering context, and it won't work. Can you give me the link to a place 
where I can find some explanation what is needed to register servlet 
application. 
 
 
Only way I can register it is to put it under 
/webapps/examples directory. That way I don't have even to register it - it 
works, but is that a real solution? 
 
 
With many thanks,

Compile problem with servlet - HELP

[tomcat user]

I'm trying to get Tomcat3.2.1 to successfully compile my JSP.

I have a base class called TrainingForm and I have a class called
TrainingFormDetail that extends TrainingForm. It's like it is complaining
about the base class. I read in the JSP1.1 spec that the type field is used
for . Note: I was able to successfully compile all
my java classes. Here is my JSP code (which is just a test for now):



<%@ page language="java" contentType="text/html" %>


<% trainingDetail.insertTrainingFormDetail(); %>

Job Title: 
Date Of Employment: 
Staff Mgr:
