RE: SESSION PROBLEM in UNIX
HI , Any suggestions on the problem reported below .I would like to add another point that this works perfectly in Linux . I have tomcat4 running in linux and the session does not become null .As I mentioned before in Windows it works fine ..Only in HP Unix I get this problem of the session variable becoming null..any specific settings that I need to check ? -Original Message- From: MUKUND Premchander [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 12:23 PM To: Tomcat Users List Subject: RE: SESSION PROBLEM in UNIX Hi, Thank you for your inputs. I couldn't implement HttpSessionListener on tomcat3.2,hence I tried with HttpSessionBindingListener before. where I added an a listener object to the session and so that when session becomes invalid then the unbound method will get called . Now as suggested I moved my application to tomcat4.1.29 and tested the same ,by implementing HttpSessionListener and also Enabled the request dumper in the server.xml. I still get the same problem i.e. after a few refresh null pointer exception is thrown when session is accessed. sessionCreated(HttpSessionEvent se) is called and I get the SOP when I load application in Browser ,but after the error occurs the sessionDestroyed(HttpSessionEvent se) is not called ( confirmed it as SOP was not displayed on the console) Also I see no difference in the dump by the request dumper for the refresh period when the problem occurred and the previous interval . Message in the log file 2004-04-21 12:02:19 ApplicationDispatcher[/MCOne] Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException Part of the request response dump: As I see it the session ID is the same and maintained . So I am unable to find out if its my application or the session management that is causing the problem.

The former interface will alert you when a session is created and destroyed, that way you will know if your session does away for example by container or just disappears, that's the bug. And still, try somehow to determine if JSESSIONID is passed with each request (use filter, HTTP sniffer or anything). If this cookie is passed, but session continuously lost, this must be the bug. And 3.x version is now outdated a little, so may be there was a bug in session handling, but nobody will fix it these days. Consider upgrade to at least 4.x serie, that way you may hope someone will help you in case of trouble. And when I gave a sop the request.getSession(false) printed the same session object .

RE: Using init parameters
Guess you are looking to access the context param init paramaters (as
specified in
context-param blocks).
The servelt config's getInitParameter corresponds to the *servlet's*
init parameters
So guess you need to use
getServletContext().getInitParameter(applicationName) rather than
getInitParameter(applicationName)

Subject: Using init parameters
I have the following in my web.xml:
context-param
param-nameapplicationName/param-name
param-valuetestApp/param-value
/context-param
My servlet class extends HttpServlet and has the following method:
public void init(ServletConfig config) throws ServletException
{
super.init(config);
configDir = getInitParameter(configDir);
applicationName = getInitParameter(applicationName);
System.out.println(configDir = + configDir);
System.out.println(applicationName = + applicationName);
jdbcAccess = new AddrJdbcAccess(configDir, applicationName);
}
Both calls to getInitParameter() return null. What's wrong here?

That way you will see if a session invalidates normally for whatever reason or it lost somehow. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Do you know how the session is being tracked in the browser? Cookie,
url? Are you saying you use the same browser in each case? Can you log
the http traffic?

Hi, How about implementing HttpSessionListener so that you know when
your session is getting created and destroyed? Also do you have
multiple users running the same jsp? If you do, you may want to
synchronize that block of code.

Hi,
I have a jsp page which is refreshed atuomatically every 10 seconds.I
get and put values in the session by using the implicit session variable
. Everything works fine for say 2-3 mins after that the implicit session
becomes null and throws a null pointer exception.
I get a null pointer exception and session is printed as null but even
the if block (session == null) is not executed .
I printed the value of request.getSession(false);.This gives me session
object ,where as the implicit session does not have this after many
refresh interval
During the first few refreshes both have the same value.
Also note that this runs fine in Windows ,I get this problem only in
UNIX . I use tomcat 3.2 in unix and view using IE in windows
I tried in tomcat 4 also I still get the same exception
FIND below the code in JSP

RE: SESSION VARIABLE BECOMES NULL AFTER SOME REFRESH
Hi ,
Thank you for your reply .
Guess I did not put my qn the right way .
In the code block
if (session == null || session.isNew()
I do not access any session variables
Actually I just redirect the page.
I am unable to understand why the implicit session variable becomes null
suddenly after some refresh and why this occurs only when tomcat runs in
UNIX .I don't get this problem in Windows

Hi There,
The NPE is coming from the { if (session == null ||
session.isNew()) } since even if session is null then you are still
trying to call a method of session.
a safer alternative would be
if (session == null) {
//error
} else {
if (session.isNew()) {
} else {
}
}
Thanks

RE: SHUTDOWN OF TOMCAT 4.1 .29 and LOAD-ON-START-UP
Hi , Find below the message on the console when tomcat shutdown is done . My console hangs at this point Feb 14, 2004 3:56:34 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on port 8080 Starting service Tomcat-Standalone Apache Tomcat/4.1.29 Feb 14, 2004 3:56:36 PM org.apache.struts.util.PropertyMessageResources init INFO: Initializing, config='org.apache.struts.util.LocalStrings', returnNull=t e Feb 14, 2004 3:56:36 PM org.apache.struts.util.PropertyMessageResources init INFO: Initializing, config='org.apache.struts.action.ActionResources', returnN l=true Feb 14, 2004 3:56:37 PM org.apache.struts.util.PropertyMessageResources init INFO: Initializing, config='org.apache.webapp.admin.ApplicationResources', ret nNull=true Feb 14, 2004 3:56:42 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on port 8080 Feb 14, 2004 3:56:42 PM org.apache.jk.common.ChannelSocket init INFO: JK2: ajp13 listening on /0.0.0.0:8009 Feb 14, 2004 3:56:42 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/234 config=E:\MCOne\MCOneServer\bin\..\conf\jk2. operties Stopping service Tomcat-Standalone Feb 14, 2004 3:57:02 PM org.apache.coyote.http11.Http11Protocol destroy INFO: Stoping http11 protocol on 8080 Catalina:type=ThreadPool,name=http8080 I am still not able to comprehend why this does not occur when i dont use load on start up .

I am not able to understand why I don't get this problem when I do not use load on start up for the servlet. It's strange indeed ;) Tomcat doesn't do anything different when you specify load-on-startup for a servlet except construct and initialize an instance of it. The lifecycle is exactly the same, no special processing. If you send the JVM a SIGQUIT after trying to shut it down, i.e. when it's hung, what active threads are showing?

SHUTDOWN OF TOMCAT 4.1 .29 and LOAD-ON-START-UP
Hi , I am working with tomcat4.1.29 standalone .I need to run it on UNIX,Linux and Windows . My webapplication has a servlet which loads on startup .This servlet starts a thread When i shutdown tomcat using shutdown.bat in windows or using the .sh in unix ,the tomcat console does not close . When i remove the load on startup and start the application via the browser to start the thread and then issue shutdown .bat , tomcat shuts down without hanging Can you please give a solution to get me out of this problem in both Windows and Unix . Your immediate response will be of immese help I also tried stopping the thread in the destroy method of the servlet but still the shutdown hangs ..(the port 8080 is released thou ) Thanks and Regards Mukund

The destroy method of a servlet is one good place to do this, so maybe there's a bug in the code you put there?
