WLS Session...help!!!

Hi,
Do any of you guys/ladies know how to maintain session on Weblogic? Does
Weblogic have Session capability like Microsoft/IIS does? The session that I
am talking about is similar with the Session on Microsoft environment....in
that you can maintain the STATE of your login. You can set Session Timeout
with it, or you don't have to request for new information (obtained from
LDAP) whenever you get back from doing other things as long as you maintain
the session (similar like Microsoft ASP Session object). Please let me know
if you know anything, or you can point me to a right direction. I, and my
colleagues, would really appreciate your help.
Sincerely,
Nico

Of course! It is part of the Servlet 2.2 specification. See
javax.servlet.http.HttpSession. You can obtain a session from a request.
See javax.servlet.http.HttpServletRequest.

[OSB10.3.1] err creating JMS stuff in OSB cluster from recorded WLS session

Hi all,
I've setup an OSB cluster with 2 managed servers.
From WLS console I created successfully the below JMS resources:
1. new file store, name and directory: MyFileStore_m01, target: bnk01osbm01 migratable
2. new file store, name and directory: MyFileStore_m02, target: bnk01osbm02 migratable
3. new jms server, name: MyJMSServer_m01, persistent store: MyFileStore_m01, target: bnk01osbm01 migratable
4. new jms server, name: MyJMSServer_m02, persistent store: MyFileStore_m02, target: bnk01osbm02 migratable
5. new jms module, name: MyJMSSystemModule, targets: cluster bnk01osbcluster + all servers in the cluster
6. new xa conn factory, name: MyXAConnectionFactory, jndi name: MyXAConnectionFactory
(targets as proposed by WLS itself: cluster bnk01osbcluster + all servers in the cluster)
+ XA Connection Factory Enabled: true
7. new Distributed Queue, name: MyDistributedQueue1, jndi name: MyDistributedQueue1, load balancing policy: round-robin
(targets as proposed by WLS itself: cluster bnk01osbcluster + all servers in the cluster)
+ allocate members uniformly: true
and I recorded that into the included recorded_by_wls.py. As said no error has been raised.
Then I removed the above JMS resources and I executed the recorded_by_wls.py from command line getting the error that I reported at the end of the email.
I changed slightly the original py produced by WLS by adding only the below first 5 lines:
print "Starting the script ..."
connect("weblogic", "weblogic", "t3://wasdv1r3n1.dev.b-source.net:7031")
edit()
startEdit()
cd('/')
I included also the recorded_by_wls.py source at the end of the email.
For information I reported also what I saw on WLS console when I created manually my JMS resources.
Do you have an idea why a successfully recorded WLS session fails when executed from a command line ?
Any help will be very appreciate.
Thanks in advance.
Regards
ferp

Hi Ferp,
Do you have an idea why a successfully recorded WLS session fails when executed from a command line ?It should not fail. Each and every successfully (activation has been done without reporting an error/conflict) recorded session will execute on other servers successfully until a unique name constraint gets violated.
In your case this violation has happened. Your script is trying to create a distributed destination "MyDistributedQueue1" under module "MyJMSSystemModule", targetted to JMS Server "wlsbJMSServer_auto_2" but a Distributed Queue with same JNDI name already exists there.
Please check.
Regards,
Anuj

Xfce4-session-helper NOT FOUND

After upgrading xfce4-session the other day,
[PACMAN] upgraded xfce4-session (4.10.0-6 -> 4.10.0-7)
These errors appear in syslog:
Apr 29 13:27:56 arch-top slim[342]: (xfce4-session:397): xfce4-session-WARNING **: Unable to launch "xfce4-settings-helper": Failed to execute child process "xfce4-settings-helper" (No such file or directory)

They appear twice, together, like above (on startup).

According to http://www.xfce.org/about/tour (one of the first hits for xfce4-session-helper), this helper was merged into a settings daemon in 4.10. Either it's a bug or you have some leftover bits from 4.8.

Hi,
Its better if u directly kill inactive session from OS by Kill command

select 'kill -9 '||spid from v$process where addr in (select paddr from v$session where username not in ('SYS','SYSTEM') and status<>'ACTIVE')
Thanks

Session Help...PLEASE!

I have a "Shopping Cart" that i got from a tutorial. I made
it work for our application but i found a problem. If i add a
product to the cart with a product name of 12345 it will add this
product fine. If i add another product with the same product name
of 12345 it will not add it to the cart and only keep the first
product name added of 12345. Basically the same product name cannot
be added to the cart, every product name has to be unique for it to
be added to the cart, we would like the unique data to be the
receiptNo and not the productName but we cannot figure out how to
do this. Please any help would be great. Thanks a lot! heres the

Make the add-to-cart process a function called, perhaps,
addToCart(). Use precisely the logic that works for
productName, but let your function add
receiptNo instead.

A dialog box tells me i already have firefox running i must close this and or restart computer this is annoying can this be fixed or am i needing better instruction for opening and closing firefox sessions help............

i have close firefox and tried to log on again i get a box saying firefox is already running, i must close this session before i can log on again confused i don't see the program running in the task manager confused again says i must restart computer in order to log on again. i close firefox by accident seems like this could be resolved easier. vs. restarting computer confused help shows something like firefox exe. confused

Try to run the Firefox program once as Administrator (right-click: Run as Administrator).
If that doesn't solve the problem then remove the Firefox program folder to do a clean reinstall.
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Runtime error when creating Sessions - help

Pls help to solve this problem.
Thanks in advance.

The most possible reason is if your site collection is reached the maximum site quota limit,then there is chance to get the run time error while creating a new group.
In this case,you will get the error while creating/updating the group or while adding the new user/uploading any content.
Also Ensure the group name is not having any special/unsupported characters.
Feel free to share the error screenshot/entry in the ULS logs.

Multi-part form problem (array & session help needed)

I have a multi-part form that consists of 3 pages(forms) which each save data to the session. When the final form is complete, I insert the session variables to the DB via a FINISH button.
I now want to take another step. Page 2 of this multi-part form allows users to add "items". Presently, they can add only 1 item, and move the page 3 by hitting a next button. I would like to add a "Add another item" button that goes to the page 2 form again, allowing more items to be entered. I believe I need an array/table to do this, but don't know how I might do this in the session.
Is it possible to create an array in the session? If so, how? If not, how might I approach this?
I am trying to avoid inserting to the database (a remote db) until after a "preview" page following the form.
Any ideas? Thx in advance.

Invalidating a Session help

When a user logs out the following servlet is called. The problem is that when the back button is hit they can get back in without signing in again. User authentication is done with a bean with Session scope. Does the invalidate() not destroy the bean as well?
import java.io.*;
import javax.servlet.ServletException;
import javax.servlet.http.*;
public class LogOutServlet extends HttpServlet
     protected void doGet(HttpServletRequest request,
     HttpServletResponse response) throws ServletException, IOException {
     HttpSession hs;
     hs=request.getSession();
     hs.invalidate();
     response.sendRedirect("../index.jsp");
help me OB1, you're my only hope.
Thanks
C.

Well, you don't clear the cache, you prevent pages from being cached.
Look at this thread: http://forum.java.sun.com/thread.jsp?forum=45&thread=562372 which states clearly how to do it. Note, you would have to add the response.setHeaders on top of every page that you don't want cached.

URGENT http session HELP PLEASE

Hello all.
i work in http session...after i redirect in https(login.jsp for example)
in JavaBean for Login.jsp try get connection with all object or JavaBeans from last http session ...but i cannot do it.
Where my problem ?
How i can have access across sessions?
Help me please.

i don't understand your meaning exactly,but i think what you mean is maybe to make a bean accessible across the session?is that right?if yes,you can set the scope attribute to session,such as:
<jsp:useBean id="..." scope="session" class="...."/>

JSP Sessions Help

OK trying to create a simple database system to log help desk issues. Created basic jsp pages to allow a user to register and login in. However I am having problems keeping track of the user when they are logged in i.e when a user logs in successfully and they are directed to the main page how can I allow the user to see that they are logged in e.g Currently logged in (theOvermind). I was told that sessions could be used. Can anyone help me with this issue.
Thanks in advance

when the user's credentials are valid then you may have to use:
session.setAttribute("username",username);The username of the user will be stored on a session variable until the web page expires its session.
Session timeout can be configure on the web.xml
In case you need to get the value of the username. you will have to use this:
String username = session.getAttribute("username").toString();if you get NullPointerException, then the user session maybe expired or user has not logged yet.. You will do the rest of the codings.

I found the above processes which do not exist in v$session.
Is this normal??
Thanks and Regards.

Hi,
>>I can see incomplete checkpoint message in alert log files.
This message indicates that Oracle wants to reuse a redo log file, but the current checkpoint position is still in that log. In this case, Oracle must wait until the checkpoint position passes that log. In fact, the "checkpoint not complete" messages are generated because the logs are switching so fast that the checkpoint associated with the log switch isn't terminated. Oracle stops processing until the checkpoint completes successfully.
In this case, normally you need to increase the size of the redo logs or add more redo log groups. Take a look on http://www.dbazine.com/oracle/or-articles/foot2
Now, as you said that the current redo size is 2 GB, how frequently redo log switch's occurs in the database ? See the SQL's below:

WLS installation help

I am in need of some serious help. I've got Weblogic (WLS_11gR1_1035) installed on my linux RHEL 5 server. Then I installed Oracle fusion middleware web tier utilities 11g (11.1.1.2) and patch set 4.
Anyways I'm trying to set up my environment and there is no /etc/oratab or /local/bin/oraenv files....
Also when I run the startWeblogic.sh script it appears that it is running although I'm not 100% sure if it is actually up... any help woudl be appreciated. Thanks.

Session help needed.

Im new to using sessions.
I have read that u can check if a user already has an assoiated session, by doing
'request.getSession(true);'
which will create a session if there already isnt one.
Well what if there is one, and i want to kill it, and start a new one?

Ok, what i really need is some info on sessions themselves. The book i have isnt very good for it (well not to me).
I dont think i understand them properly.
Q1. Do sessions exist before they have been manually created?
Q2. When is a session created?
This is the first time i have dealt with sessions before, so am clueless. If anyone can offer me some advice, or point me towards a VERY good guide about seessions, i would be very greatful.
Thankyou

Help about W2K Apache plug-in for WLS

Hi,everybody.
I want to use the W2K apache http server for redirect the dynamic request to
WLS. But i don't have the corresponding plug-in. Who can help me? or Who can
give me some hint about this?
Thanks in advance.

Hi Steven,
as far as I know there is no Apache Plugin for Windows Platform. Your
choice is either Unix->Apache or Windows->IIS. I think there is a
Netscape Plugin as well, but I don't know for which platforms.
