Listing Active Sessions
Hi All, Could some one tell me how tolistall the sessions which are active at a particular instance?Iguess the interface HttpSessionContext can be used for this, but API doc says, it has been deprecated with no replacement. Could some one suggest an alternative way out please?? I'm using JavaWebServer 2.0 Thanks in Advance. Rao.
Re: Listing Active Sessions
Well, so has Java Web Server (deprecated) :) It depends on your particular server - different servers use different session managers. The iPlanet server has a open-source session manager so perhaps you could use it to suit your needs.

I guess the interface HttpSessionContext can be used for this, but API doc says, it has been deprecated with no replacement. Could some one suggest an alternative way out please?? Check on the archives but the way I normally do it is to double reference. ie: every time I create a session I put a reference to the objects I put in a session elsewhere (ie: outside the session manager). I can then do what ever I like with them, as long as I delete them when the session gets collected. Note: you only need this technique very rarely. It's a *very* good idea to avoid this sort of thing if you possibly can.

Classpath?
Hi I'm sorry for posting a basic question in this advanced forum. I've installed JavaWebServer on my system and the class path is set to its lib/servlet.jar, which is working fine. When I use a similar class path in another system, the error message saying javax not found in import is displayed. What could be the reason??

Re: Installation of JSDK2.0 ?
Is there newer JDK version ready for developing servlets? Or I have to install JSDK2.0? If so, how to setup the classpath correctly (under Windows 98) for compiling the source code using standard javac compiler ? Yes, there is a newer version of JSDK - check java.sun.com for it. Unfortunately (and to my best knowledge) JServ only supports 2.0 so if you're using apache+jserv you have to use it (it can be downloaded from the SUN's site as well). You can also download sun's JSWDK - it's coming with a simple web server as well and supports the latest version of JSDK. Coming to correct installation, there is a file 'jsdk.jar' and you have to include it in your classpath.

Hi Rao, There is a good reason why access to other servlets and sessions via the Servlet API has been deprecated and in most cases deprecated properly, namely security. If you can access them so can anyone one elses Servlets and JSP's which is not a good thing. You could setup all of your servlets such that session object references are stored in a central storage object however you may have problems when the server is restarted (Session objects are quite often persistent) so you would have to have some way of updating your session reference object each time a session object (via getSesstion methods) is grabbed from the session pool. While it might seem like a good idea to make your session reference object persistent as well, it is not because the sesssion objects you would be storing in your .ser file will no longer be the same session objects that the server restores (it has its own session store). Just out of interest, why on earth do you need to be able to track all sessions? Andy Bailey

Re: new to JDBC !!!
Your 'result' definition is not the problem.
stmt is defined in init() which makes it local to that method, but you are
trying to use it in doPost(). You need to define "Statement stmt" outside
the methods which will allow both init() and doPost() to to execute methods
for that class -
public CLASS xxx extends HttpServlet
{
Statement stmt;
public void init(ServletConfig cfg) throws ServletException
{
stmt = con.createStatement();
...
}
... doPost(..)
{
// Same commands as you have below...
}
}

If you check the API (grrr) you will find that sessions objects can have listeners on them which recieve certain events, one of those is the session being destroyed becuase it's out of date (ie: the user has not logged out). Implement a listener and have that destroy your duplicate copy. Nic ___ To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff SERVLET-INTEREST".

Re: Auto reload??
Think the following scenario : 1 - a servlet engine servlets spy component executes an active polling to see if your_servlet.class has been updated into your web application deployment directory or your .war. 2 - if so, this spy emits an event to trigger a new class loading operation to substitute the new version to the old. But I have another question about the normal behavior of the automatic reloading functionality : If my servlet current instances deals with a session even if not active (executing its service method) when the update occurs, what happens? Is there a mean to preserve some data like session data from old to new instances? Is there a mean to deactivate the automatic reloading programmtically, during bounded periods like sessions?

Maybe i am missing something here but as far as i know the HttpSession object will be invalidated when the browser is closed.After a while it will be destroyed by the servlet engine. So if a user closes the window and than he comes back after a while even if you track his IP,his session is very likelydestroyed. And another thing: one IP address is not enough to track an user (machine) the request.getRemoteAddr() ussually returns the proxy IP. So maybe you want to check for some headers too like "x-forwarded-for". If iDIDN'T missunderstand You i would suggest using cookies and implementYour own session like YOU described. p.s.

Re: stop
David, actually we need to load another page immediately after the servlet starts, so the white page comes after the other page, Couldn't you write a Thread that does the work for you ? You spawn the thread, and send the page you want to send. IMHO, you shouldn't let your servlet do a lot of db work. You spawn the thread and send the page you want.

You went wrong in the init() method. In your case con and stmt are local
to the init() method. You should declare them as Fields of the class
(e.i. declare them right after you declare the class
public myclass{
Connection con;
Statement stmt;
public void init(){
con = ...;
stmt = ...;
}
}
This way it should work

Character Encoding
Hi,
We are using Japanese Sun Solaris for the server. The webserver is Apache 1.
3.9 and Jserv 1.1.
For the following statement
System.getProperty("file.encoding") in a normal Java application I get the
result as
EucJP
Now if we run the same statement in a Servlet on the same machine we get the
result as
ISO8859-1
Could you please throw some light on this.
Regards,
Sumit

Re: DB2 jdbc driver servlet.
If it works fine in your regular application, the only thing I can think of
is whether you had your jdbc driver included in your web server CLASSPATH
environment. Web servers in general do not use your system CLASSPATH.

Re: servlet and jdbc
Hey!
You don't say what servlet engine you are using. But you must have the
DB driver classes in the engine's classpath. WebSphere allows one to use
the system classpath or the servlet engine's class path. Make sure you
know what path is being used.
You can look around in your admin.config, but this may be specific for
WebSphere. Your engine may be different.
Or you can write a small servlet that does something like this:
java.util.Properties props = System.getProperties();
enum = props.propertyNames();
Then iterate on this enumeration with this:
name = (String) enum.nextElement();
props.getProperty(name)
That should get you all of your properties and I believe the
classpath will be there.
Good luck.
Sans adieu,

Re: new to JDBC !!!
Hey!
I disagree with the way you are doing your DB connection,
but there are some very good servlet developers on this
list that disagree with me.
I don't put DB connections in the init(). Why you say.
Because I don't want any of my developers taking a long
term connection to my DB.
I put my connection code just before I need it and then let
it go as soon as I am done.
BTW, if you are truly doing the MVC you don't put the business
model in you controller code anyway. Try a different approach
like:
Creating a method() that is called inside of your doGet()/doPost().
Pass in your Driver, URL, props and query string and pass back
the result set. This is not perfect separation but it's a bit better.
A better way is to have a DB class that holds your business model.

ResultSet result;
if(req.getParameter("action").equals("publisher"))

result=stmt.executeQuery("Select * from BookDetails");
msg=result.getString(4);

Purpose of Servlets
Hi! Could you tell me what is the purpose of Servlets? What function are they performing? As I understand they are run on a server but I don't know what exaclty are they run for. Is it to provide a better and secure way to get info from the clients? thanks asher Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff SERVLET-INTEREST".

Re: Java.io.IOException
Hey! This is not a servlet issue, but I would look at the DataStream you are using. The error is most likely there.

Raghu: Thank you for your suggestion. It does not work yet. I just installed Jrun on my server.I want to test whether I have installed it correctly. - Original Message - From: raghuk [EMAIL PROTECTED] To: mark peng [EMAIL PROTECTED] Sent: Saturday, April 29, 2000 1:05 PM Subject: Re: Pls Help me out Mark, if you have tried to deploy any classfiles dynamically into the JRUN/Servlets directory, then this problem would occur. Ofcourse, this is only one of the possible reasons. Try this : Stop JRUN service manager(JSM). Wait for couple of minutes. Start JSM again (in application Service Mode). If this doesnot work, let me know. I will give you a check list for verification. All the best !
