Session problem using tomcat 3.3.1

Hi all,
Does tomcat support session.?.
I came to know that, tomcat is not supporting session, actually, it kills the session variables when redirecting the response to other page..
Is it so?..
please confirm me..
In my application we are using session variable to store the user access rights, and validating in all jsp pages. we are using resin 1.2.5 as servlet container. It is working fine.
we have an approach to port our application to tomcat instead of resin.
Now, while porting the session variables not retreived in the jsp pages.
I am struggling with this issue for the past one month, so please confirm me regarding tomcat supports session or not.--
Thanks and regards,
Murugan

hi
Well, in my application, i have session variables, and it is working
fine. Except in one jsp page where each time I submit, a new made
Vector disappears.
But the others session attributes are still there (rights, user,
etc ...).

Session problems in tomcat 5.0.28

Even I shutdown the tomcat 5.0.28 server the session variable is still existing and it is showing the old values. What I have to do to disable the old values? Is it the problem with tomcat 5.0.28 or with JSP coding!

Tomcat serializes sessions to the hard drive when it shutsdown. If you don't want this you have three choices:
1: you can disable this functionality in the server.xml. Check the documentation.
2: you could just delete the session.ser file when you shut down tomcat. This file is under work/standalone/{webapp name}
3: you could close and re-open the browser so that the old jsessionid will not be sent and a new session will be created. The old session will eventually time out.
The third option is probably the easiest.

Problem using Tomcat 4.1

I'm trying to establish connection with the database from JSP.When I'm running it's giving the following error
"oracle.jdbc.driver.Oracle.Driver class not found"
I'm using Tomcat 4.1 and database is Oracle 8i.I've already set the classpath."C:\oracle\ora92\jdbc\lib"(Oracle is intalled in C drive).
Kindly help me resolve this issue.
Bye.

Tomcat does not use the system classpath.
As far as Tomcat is concerned the classpath for a web app is
1 - web-inf/classes
2 - jar files in web-inf/lib
3 - jar files in [TOMCAT]/shared/lib
4 - jar files in [TOMCAT]/common/lib
If you are going to be using Tomcat's connection pooling, you need the JDBC driver jar file in [TOMCAT]/common/lib
I would recommend you put the file ojdbc14.jar (or equivalent) in the [TOMCAT]/common/lib directory
Restart tomcat, and try again.

Hi,
the petstore needs some of the services of a Java EE 5 application server to run. It uses some technologies that are part of Java EE 5like annotations, Java Persistence Objeects, JSF 1.2 etc.
This FAQ lists some of the things needed.
https://blueprints.dev.java.net/petstore/faq.html#tomcat
You would have to do some work yourself to get it to run on tomcat as there are not full instructions on how to do this.
hth,
Sean

paste the sample class file in,restart tomcat. i work again!
what is the problem!
even i compile the code inside the Jcreator, after set required libraries to servlet.jar or servlet-api.jar
compile it, success then run it in IE, same error!!!.
what should i do.
stil a beginer in servlet and jsp anyway.

and Apache tomcat originally dont have servlet.jar but servlet-api.jar, i copy the servlet.jar from my friend servlet.jar is an OLD version, you should only use servlet-api.jar!
wrong name: HelloWorldPerhaps there is a mistake in the class or packagename of the source file. Post the source here.

Session problem using mozilla browser

I am involving an application development.
I opened 2 moilla fire fox browsers at the same time and enter 2 different username and password.
After login, both browsers showing the one user information only,
It is working fine in IE.
PLs help me to resolve

There is nothing to resolve, different firefox instances share the same session. It's not a bug, it's a feature. If you want two different sessions, use two different browsers like you are already doing with firefox + IE.

Serious problem of jdbc-mysql connectivity using tomcat

hi everybody
i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
after doing so i have followed 2 methods :
method 1st:........
i have made aone more jar file from the following .java file....
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class TestSQLLoad
String user = "Not Connected";
String pwd = "no pwd";
int id = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null ) {
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
user = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
String q = "select name, password, id from user";
ResultSet rst = stmt.executeQuery(q);
if(rst.next()) {
user=rst.getString(1);
pwd=rst.getString(2);
id = rst.getInt(3);
conn.close();
}catch(Exception e) {
e.printStackTrace();
public String getUser() {
return user;
public String getPassword() {
return pwd;
public int getID()
return id;
after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:

after all this i have taken a jsp page whose code is here:
(the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
<html>
<head>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
when i run this page on the browser i get a lot may errors stating
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /testdb/test-db.jsp
Generated servlet error:

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
AND NOW WHEN just to get rid of such errords i try to include a statement
<%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
<html>
<head>
<%@ page import="pkg.TestSQLLoad" %>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
now when i run it i get the following errors:
exception

in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
that too gave me the following errors

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

THE 2nd Method:
in my second method i did the same changes in the web.xml and server.xml
then i took a jsp page with the following code:

so better if u plz guide me in that regard

JSF & Tomcat 5 session problems

I am implemeting a web application using JSF and tomcat authentication. The problem is that tomcat is losing the session when I hit refresh on any of the pages which are marked as havign a security constraint.
e.g. you go to index.html -> takes you to login.jsp (as you need to log in first), you log in successfuly and go to index.html, you hit refresh and get taken back to login.jsp.
Any help would be much appreciated.
If anyone has implementign an app using tomcat authentication and jsf, I would be grateful if they could tell me how they are managing to overcome this issue.

I have a similar question, but not about session timeout, but managing the data within your session. In our previous homegrown JSP Model 2 Framework, we had various methods in place to cleanup the session for a page (essentially allowing you to cleanup the managed beans after you were done with a page). Due to constant activity, the sessions never timeout, but there is "dead" data in the session. How would you do this in JSF? For example, lets say you go through a wizard set of screens, where once complete, you don't want the managed beans to exist in the session anymore. Where would you tap into the JSF lifecycle to do this?
Thanks in advance,
Dave

Tomcat and JavaMail Sessions problem

I'm using Tomcat (with struts). I've configured my web application in server.xml to manage JavaMail Sessions:
          <Resource name="mail/Session" auth="Container" type="javax.mail.Session"/>
          <ResourceParams name="mail/Session">
               <parameter>
                    <name>mail.smtp.host</name>
                    <value>gandalf</value>
               </parameter>
          </ResourceParams>
Also, I've configured my web application deployment descriptor (web.xml) to use this resource:
<resource-ref>
     <description>JavaMail Resource</description>
     <res-ref-name>mail/Session</res-ref-name>
     <res-type>javax.mail.Session</res-type>
     <res-auth>Container</res-auth>
</resource-ref>
Now in the Java code I try to get the JavaMail session in this way:
private Context devuelveContexto() throws javax.naming.NamingException
initContext = new InitialContext();
return (Context) initContext.lookup("java:/comp/env");
public javax.mail.Session devuelveSesionMail()
throws javax.naming.NamingException
Context envContext = devuelveContexto();
javax.mail.Session mailSesion = (javax.mail.Session) envContext.lookup("mail/Session"); <--- this throws an exception
I'm doing all like is explained in Tomcat help web page 'JNDI Resources HOW-TO' but it doesn' work for me.
The exception raised is this:
java.lang.reflect.InvocationTargetException: java.lang.ClassCastException: javax.mail.Session
     at com.aplicacionesweb.evaluaciones.ddbb.CargadorRecursos.devuelveSesionMail(CargadorRecursos.java:76)

     at org.apache.struts.actions.DispatchAction.perform(DispatchAction.java:236)
     at org.apache.struts.action.ActionServlet.processActionPerform(ActionServlet.java:1787)
Please help.

Problem solved. I had 'mail.jar' and 'activation.jar' in 'WEB-INF/lib' directory, causing a classes conflict.

Viewing Excel Files using Tomcat - Problem with caching

Hi all,
A small part of an application I'm writing has links to Excel files for users to view/download. I'm currently using Tomcat v5 as the web/app server and have some very simple code (an example is shown below) which calls the excel file.
<%@ page contentType = "application/vnd.ms-excel" %>
<%
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
response.sendRedirect("file1.xls");
%>
This all works except but I'm having one big problem.
The xls file (file1.xls) is updated via a share on the server so each month, the xls file is overwritten with the same name but with different contents. I'm finding that when an update is made to the xls file and the user then attempts to view the new file in the browser they recieve only the old xls file. It's caching the xls file and I don't want it to. How can I fix this so that it automatically gives the user the new updated file.
The only way I've managed to get Tomcat to do this is to delete the work directory and delete the file from my IE temp folder and then restart Tomcat - this is a bit much!
Any help would be greatly appreciated.
Thanks.

I'd a problem with caching a few years back, for a servlet request which returned an SVG file.
As a workaround, I ended up putting appending "#" and a timestamp / random number after it. The browser assuming each request was new, and didn't use the cache.
Eg.
http://myserver/returnSVG.do#1234567
where 1234567 is a timestamp / random.
Not sure whether you can do this on a file based URL... but maybe worth a shot...
regards,
Owen

Problem setting Unicode (utf-8) in http header using tomcat

Hi:
I am trying to set a file name in utf-8 to http header using the following code:
response.setContentType("text/html; charset=utf-8");
response.setHeader("Content-disposition", "attachment; filename=解決.zip");
// I actually has file name in utf-8 here to set to the header, and I know that the name is correctly
// and I also looked into the response object MimeHeaders object and saw the head is correctly there
then write the content of zip file using ServletOutputStream.
The problem I have is that the file name is not displayed correctly when prompted to save or open in the pop up window next. I found out using Fiddler that the request header is wrong:
Content-disposition: attachment; filename=�zn��.zip
I am using Tomcat 5.0.28. Any idea how to get this working?
Thanks in advance!

You are setting the charset for the content to be UTF-8. (That is why the method is called setContentType.) But HTTP headers are not part of the content and so that has no effect on the header.
The original specification for HTTP only allowed US-ASCII characters in headers. It is possible that more recent versions have features that allow for non-ASCII header data, but I don't know if that is the case or how you would use those features if they exist.

Problem in Server side includes using Tomcat

Problem in Server side includes using Tomcat:
I am trying out small programs in servlet.
I get one example program for server side includes from net.
The code is:
<HTML>
<HEAD><TITLE>Times!</TITLE></HEAD>
<BODY>
<P>
The current time in London is!!! :
<SERVLET CODE="CurrentTime" codebase="../servlet">
<PARAM NAME="zone" VALUE="GMT">
</SERVLET>
</P>
</BODY>
</HTML>
I placed this test.shtml file in tomcat-home/webapps/ROOT folder and i kept the servlet in WEB-INF/classes folder.
I renamed the servlets-ssi.jar and i removed the comments for SSI in web.xml file.
When i run the servlet separately, i am getting the correct result. But if i run shtml file with the URL : http://localhost:8080/Test.shtml,
i am getting the result as:
The current time in London is!!! :
It is not invoking servlet program.
CAN ANYONE HELP ON THIS!
Thanks.

Thanks...as u said I tried putting dir & found that
my file was saved as Ch1Servlet.java.txt instead for
Ch1Servlet.java......So that was a problem.Now I'm
able to compile.Oh, yeah. Notepad will do that to you. I think when you save in Notepad if you put quotes around the name "Whatever.java" then it won't add the .txt.
But on compiling I'm getting the following error
package java.servlet.* does not exist
package java.servlet.http.* does not exist
package java.io.* does not exist
Do u the reason for this??? The servlet stuff is java[b]x.servlet. For the io stuff, I don't know, I'd have to see your code. Either you have a typo or a corrupt installation.
