Tomcat session expires after compiling servlet/ class

Hi,
Does anybody know why tomcat(4.1) session expires if you modify a serlvet or class and compile it.
After compiling I refresh the page and I get session invalidated page. And every time I compile I have to relogin.
Any ideas ? Is there a work around ?

In serverl.xml, if you have set the reloadable="true" attribute in your <Context/> tag for your web application then each time one of the servlet classes is modified, tomcat will reload the web application. Set reloadable="false" and this will stop.

Problem in compiling servlet class - using Tomcat

Hi,
I have a servlet pgm that I'm trying to compile.I using Tomcat application server.I have my servlet class in D:\servlet_wrk\project1\src
and my deployment descriptor in D:\servlet_wrk\project1\etc
my CLASSPATH var is set to C:\Sun\AppServer\jdk\bin
and
my PATH var is set to C:\Sun\AppServer\bin.
When I compile my servlet class Ch1Servlet.java in the command line from the directory
D:\servlet_wrk\project1 using the command
javac -classpath D:\applications\tomcat-5.5.12\common\lib\servlet-api.jar -d classes src/Ch1Servlet.java,
it says error:cannot read: src/Ch1Servlet.java
Can somebody help me to solve this problem and help me to compile my servlet class.
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.

Compiling servlet class:javac gives 'bad command'

I have a servlet class in the path: E:\Tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes
I am using Tomcat 3.2.4 and Just Go (the tomcat launcher) provides this log of my settings:

I'd greatly appreciate it if anyone could tell me what path to use in DOS to enable me to use the javac command.
My problem is there are so many paths in the Tomcat settings (above), I am not sure which one to use to compile my servlet.

Thanks for the suggestion. I am not trying to use JBuilder, just the command line from DOS so I hope that won't impact this.
JAVAC is in e:\jbuilder35\jdk1.2.2\bin
and the class that I am trying to run is in:
e:\tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes
and it's called CookieExample.java
Here's a copy of my DOS Screen of what I did and the result:
E:\>set path = javac e:\jbuilder35\jdk1.2.2\bin;%path%
E:\>cd e:\tomcat324\jakarta-tomcat-3.2.4\webapps\examples\WEB-INF\classes

Portal Session Expiration after 10 minutes.

Hello Experts,
We are running on EP 7.0 ABAP+JAVA stack.The UME has been configured on ABAP stack.
We have a requirement to auto logoff the portal if no activity is done for 10 minutes.
I have gone through SAP Notes and came to know this is not possible in current portal framework. In some threads I got clue to set some parameters for SSO expiration and Security session expiration but that did not gave desired result.
I have set the security session to 10minutes in Visual administrator.(default 27h) [Security Provider -> SessionExpirationPeriod ]but nothing happened I am still in portal session after 10 minutes.
I made the change in -> /usr/sap/<SID>/<inst>/j2ee/cluster/server0/apps/sap.com/irj/servlet_jsp/irj/root/web-inf/web.xml
And change the session time out to 10 minutes. But same result nothing happened.
Please guide what settings I am missing. What else I have to do to get the session expire.
thanks & regards
shankar

Hi,
Check this:
Redirect user to a custom "logoff" page after 10 minutes of user inactivity

Session Expired after logging on to Visual Administrator - SLD Config

Hey Guys,
I have a NW2004s installation, both ABAP and Java stack, with UME pointing to the ABAP stack.
I created a user in ABAP stack, and assigned the J2EE_ADMIN role to this user.
I try to log into the Visual Administrator with this user. The login is successful.
However right after I navigate to the sld data supplier node and click it, I get the error message, Session Expired.
I think it is because I am not authorized to configure SLD or something like that.
When I created the user in the ABAP stack I entered all the roles for the user with which I am logging on to the Visual Admin:
SAP_SLD_ADMINISTRATOR
SAP_SLD_CONFIGURATOR
Anyhelp so that I can get over this problem and configure the SLD in the system.
Thank You.
Sumit.

J2EE_ADMIN role has all the rights(configure SLD etc) , make sure you configure the SLD and import the CIM model content you can login to SLD at http://<host>:5XX00/SLD and then access the data supplier bridge
where XX is your instance number

Session expires after the script1 in the job is over

hi,
i created a job. in my application i have to maintain the session. in the job, when script 1 gets over, and script starts, i dont know for what reason, the session expires. can this be due to cookies??

If the session is needed for the second script in the job, then try to change the following settings for the second script using Options -> Current Script -> Playback -> Script. In the Automation Actions frame, uncheck the first three checkboxes for Reset Browser, Start new browser session and use distinct cookie directory. Also remember to uncheck the checkbox for Use same settings for all new scripts, that is the last option on the Current Script Setting dialog. Otherwise the above settings will apply to any of the new scripts that you create.
Hope this helps.

Set up the classpath for tomcat 5.0 to compile servlet

I am totally confused how do you set up the class path, i use this command:
c:\set CLASSPATH=.;C:\tomcat5.0\common\lib\servlet-api.jar;%CLASSPATH%
and I compile my file which i put in j2sdk1.4.2_10\bin
here is the command line:
c:\j2sdk1.4.2_10\bin\servletexercise1.java
and it gives me the error message to say that it can't find the servelt, javax.servlet.
Please help! thanks in advance!

I am totally confused how do you set up the class
path, i use this command:
c:\set
CLASSPATH=.;C:\tomcat5.0\common\lib\servlet-api.jar;%C
LASSPATH%I don't have a CLASSPATH environment variable on any machine that I work with.
and I compile my file which i put in j2sdk1.4.2_10\binThat's a pretty stoopid place to put a Java source file. You shouldn't be putting any files in that directory.
The right thing to do is to add the Java /bin directory to your PATH environment variable. When you do, make sure there are no spaces in the path name. (e.g., don't install Java to the "Program Files" directory) OR replace it with its 8-char DOS equivalent (e.g., c:\Progra~1).
here is the command line:
c:\j2sdk1.4.2_10\bin\servletexercise1.javaSorry, I don't see where you execute javac.exe.
and it gives me the error message to say that it
can't find the servelt, javax.servlet.
Please help! thanks in advance!What is this telling you? That the javac.exe totally ignores the CLASSPATH that you set? (Hint: Right answer.)
The correct way to do it is to use the -classpath option on javac.exe.

Session expires after popup windows

I am using JDeveloper 9.0.3.10.
I need to use the javascript function window.open to open a new (popup) dialog. I lose my session after I close the new dialog and since I validate my session in everypage, I get forwarded to the login page after opening any popup.
This only happens when I run the application locally in JDeveloper. I do NOT have this problem when I deploy the application on a server.
I'd really appreciate your help.

I had that problem too and it seems to be a bug in Internet Explorer.
It seems that IE tries to keep a count of how many windows are interested in the current session, and when you close the last one, it gets rid of the session cookie. But it gets the counting wrong sometimes.
It especially gets it wrong if the browser has gone from a file-url to an http-url (!). Which explains why it breaks when you run it from jdeveloper (the webapp runner loads a local file into the browser and then goes to the proper url).
If this is what's causing your problem then you will probably find that if you run your application from jdeveloper, make a note of the url, then immediately close that browser (because it has been through a file url so it's going to get its counting wrong) and open a fresh one, paste the url into that fresh browser and everything should work fine.
I think the bug has been in IE for a long time.
There's an article about it here:

Session Expired error in browser

Hi guys,
I hope everyone had an excellent festive period. I have been trying to access certain parts of websites and after I have successfully logged in and trying to access the member section i receive this error:
Session expired
Why does my session expire?
This could be either...
For your security, your session expires after 10 minutes of no activity. This means no link has been clicked or data has been submitted in last 10 minutes.
You have entered the URL of a particular page, which cannot be viewed without prior authentication.
I have previously accessed these websites on my PlayBook but I am unable to any longer. These include the Etihad careers section along with the Emirates careers section.
I have tried clearing the browser history, cookies, cache and local storage along with restarting the PlayBook, but all to no avail.
Any help would be greatly appreciated.
Regards,
Dave

I completely miss read that my apologies. I have tried the hard reset and still to no avail. Any other suggestions would be greatly appreciated. I have also tried the bridge browser and I have also tried the basic browser and also the comic sans browser and all of these have the same errors as well.

Session expired within 10-20 seconds while working on Visual Administartor.

session expired within 10-20 seconds while working on Visual Administartor.
Details: In VA, each dispatcher and Server process have four components:
kernel, Interfaces, Libraries and Services.
While working on Kernel in VA of dispatcher or Server, I'm getting 'session expired' after every 10-20 seconds.
I'm not getting the same 'session expired' problem while working on interfaces, libraries or services.
After 2-3 minute of wait, again i'm able to work on kernel but again after 10-20 seconds, session get expired.
Pls suggets to resolve this problem. We are on SP level 20.

For all managers in kernel, i'm not getting this problem.

Varing the session expiration time

Hi all,
the default session time with my server and the ADTB are too short (24 mins)
Do you have a PROOFED WORKING way to extend the session lifetime?
I tryed both to use the .htaccess variable and the ini_set("session.gc_maxlifetime")
If I query then the ini_get("session.gc_maxlifetime") I get the new session length I decided.
But in fact the session expires after a very short time?
Any help would be really appreciated
A. F.

Hi Fonzie,
if neither the .htaccess approach nor the ini_set function work on your host, I fear I have no idea what you could do instead, as the host admins seems to have disabled both features for whatever reason.

Tomcat servlet class not refreshing

I just started to work with Tomcat.
My problem is that once I have compiled and put a servlet in myApps\WEB-INF\Classes directory even after I recompile it the browser displays old version. Only stopping and starting Tomcat shows the new version
My browser is IE v 6.
I have done everything as instructed in the book Java for the Web with Servlets... by Kurniawan.
My web.xml looks like so
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
<servlet>
          <servlet-name>Testing</servlet-name>
          <servlet-class>TestingServlet</servlet-class>
</servlet>
</web-app>
My CLASSPATH variable looks like so
c:\j2sdk1.4.2_01\lib;.;c:\1ourfolder\Java Stuff;c:\jakarta-tomcat-4.1.27\common\lib\servlet.jar;C:\IBM\SQLLIB\java\db2java.zip;C:\IBM\SQLLIB\java\db2jcc.jar;C:\IBM\SQLLIB\java\sqlj.zip;C:\IBM\SQLLIB\bin;C:\IBM\SQLLIB\java\common.jar
Is there something I need to add in the web.xml file? On the comp.lang.java.help forum there was reference to the WEB-INF\classes directory being in classpath and removing that made it work but I don't have that situation AFAIK.
Thanks

This must have been answered many times but with the software evolving as it does there must be different ways of doing this. This is what I did
On your browser go to the manager page.
http://localhost:8080/manager/html
You may be prompted for a userid and password
If you haven't done so already edit the conf\tomcat-users.xml file in the tomcat directory and add a line to set you up as a manager. This is going to be something like this
<user username="manager" password="tomcat" roles="manager"/>
Login as manager/tomcat.
On the resultant webpage you should see a list of applications, myApps will be in that list. Stop it and start it (follow the grid to the right)
Now your servlet class will be refreshed.
I looked at other responses in this forum and found this answer
http://forum.java.sun.com/thread.jsp?forum=33&thread=404559
"...If it is tomcat 4.1 then you can use its adminitrator jsp page to make your context(webapp) reloadable. This in turn will make chages to your your server file and will add the context back to tomcat without stopping it..."
At this time I haven't figured out how to do this ;-)
Oh, and could you use code tags the next time?

How to install servlet classes in order to compile a simple servlet...

When trying to compile a simple servlet (java file), I get errors having to do with not finding any object of the javax.servlet class. I am using J2SE v.1.4, and from what I know, it does not have built-in support for Servlets-JSP.
Do I need to install myself the servlet classes (downloaded from Sun's site) in order for my servlet to be able to compile and work under tomcat? And if so, where should I put them? Or is there something else I have to do?
Thank you in advance for your assistance!

If you have Tomcat already, the files you require are in:
(Tomcat4)
[TOMCAT_HOME]/common/lib/servlet.jar
or
(Tomcat5)
[TOMCAT_HOME]/common/lib/servlet-api.jar
[TOMCAT_HOME]/common/lib/jsp-api.jar
This file needs to be added to your classpath when compiling a servlet.

Tomcat session expires after compiling servlet/ class
