Session is set for every request

Hi,
With WL Server 6.1SP1 we have some peculiar problem. Every request
is considered as a new request and a new session object is created. So
the information we stored in the session is no longer available for
subsequent requests. This behaviour is seen intermittently. Session is
not invalidated and session is not timed out.
Thanks,
Prasad

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Session gets created for every request.

Hi ,
I have two servlets where i set a object in the session in one servlet say servlet1.java and get in another servlet say servlet2.java.
When i pass my session object from servlet1 to servlet 2 , servlet2 is supposed to get the arrtibute , but its always gives me a null value.
I found out that a new session is getting created every time when i try to access servlet2.
I tried to print the session object , and it clearly tells me that the object is differet from the one i set.
Can anyone let me know why is this happening and how do i solve this .
This happens for me in weblogic 8.1 setup.
In my JBOSS set up with the same code it works fine.
Thanks in advance.

Sasikanth,
Pardon me if I am stating the obvious, but according to your description the problem is with WebLogic. So did you try a WebLogic specific forum?
Good Luck,
Avi.

Is lookup required for every request(SLSB)?

Hi,
I have a SLSB and a client that makes frequent requests as needed. The question is, should the client make a fresh lookup for every request in a session or just once per session?
I have tried both the ways and got it to work...but can someone tell me the correct approach for lookup?
thanks in advance.

Thanks for the reply!
By your statment that EJB Home Handle can be cached, I understand the following..
MyBeanRemote mybean = null; // declaring as class variable.
// making a request
if(mybean==null)
lookupBean();
mybean.doSomething();
// making next request
if(mybean==null)
lookupBean();
mybean.doSomethingMore();
// here goes the lookup...
lookupbean() {
mybean = ...lookup("......");
}so, this is how before each request, I check if the mybean is null. in lookupBean(), the bean-lookup process is executed and reference is set to mybean.
am I right?

Client handler is invoking for every request.

Hi EveryOne
i am new to JAXWS welogic.
i have a web consumer/client, while sending the request from client the handler is invoking for every request. I could not able to restrict.
i would like to intialize only once and need to use that instance like (init() method initialization). How to resolve this issue.
can anyone come across a solution for JAX-WS in general? Please throw your thoughts here.
Any help in this regard would be appreciated.
Thanks & Regards
Suresh

Two common reasons for this are:
(1) Problem with the system clock: date, time, or time zone differs substantially from the rest of the internet
(2) Firefox not set up to work with your security software that filters your web traffic
In order to filter secure traffic, your security software needs to present "fake" certificates to Firefox so it can be the "man in the middle" and see everything sent to and from the site. Firefox distrusts the fake certificates until instructed otherwise.
Do you use any software with that kind of feature? On Windows, products with that feature include avast! 2015, Bitdefender, ESET, and Kaspersky.
A less common problem is malware performing a "man in the middle" attack.

Specify filter for every request except one

Can a in me web.xml file specify that a filter should be used for every request except one.
I can write;
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
to use it on every request. But how do I exclude one specific resource that shouldn't go though the filter.
I know that this may not be exactly the right forum but i'm really lost. I appreciate all suggestion.
Thanks / Daniel

This is the right forum, but unforutanetly you cannot exclude some urls.
I would suggest you handle that logic in the filter itself.

Alternatives to loading .properties files for every request

I am just starting for a company, and they loading a bunch of .properties files for every request. I've told them that according to JEE specs, using the file system like that is a violation, as it's not scalable. I've suggested the following alternatives:
1. Load a file once, in a static initializer, or something to that effect. Re-start the app if a change needs to be made in properties.
+: few changes
-: requires a new war/ear to make a change
2. Put properties that are truly variable in a database record.
-: requires DB schema change.
3. For instance, i've though about using something like jconsole to change an mbean property, and then web apps using that property.
4. Define a single web app that exposes an EJB/JMS/RMI object which serves properties to other web apps. If a change is needed, only 1 web app needs to be re-started, although it would still have to be re-packaged. Perhaps this app could load this stuff from the DB.
5. Have a properties service, and expose it as an RMI object. If a change needs to be made on the fly, use rmi to make the updates.
I'm leaning towards a combination of 1, 5, and possibly 4.
I would like to know what other alternatives might be available.
Thanks.

New instance for every request to Servlet

I want to create new instance for every request to Servlet ...
I am running my servlet on weblogic

Hi!
what functionality can there be that has to be put into init()?
Another idea:
why not include your needed functions in a private method within the servlet and call this method from init() and from doPost/doGet so it is processed any time the servlet is called?
btw: more instances of the same servlet seems to me as going back to the roots (cgi).

Servlet 2.3 - Filters for every request to the WebContainer

I want to filter every request to the web container. How do I deploy the filter without confining it to a particular context? For example, I would want to filter everything that went to www.bea.com. But if I deploy it as a webapp, it will only filter from www.bea.com/mywebapp. So I lose any request that go to www.bea.com/anothercontext. I have tried mapping the filter to the FileServlet, but once again, it only works inside of the context of the webapp.
          Is there a way to map the Filter to the docroot of the server?
          I am using Weblogic 6.1 and am currently deploying every thing as a .war file


yep - thats my understanding
          I dont know of a way to deploy a single filter at the server level that
          covers all webapps. I'm not saying there isnt a way - I don't know of one
          Anyone out there know for sure?

The VTY sessions are set for SSH, is telnet still open?

I'm in the process of enabling SSH on all of my routers, switches and firewalls. After upgrading the IOS to one that supports SSH, generating the crypto key and then setting all of the VTY sessions to SSH only, my security team informs me that telnet is still vulnerable to IP spoofing. They can demonstrate that when they launch a telnet session to one of my routers, the telnet session will pause for maybe 2 seconds before receivign the message that the session was terminated by the router. They claim this indicates that the router is responding to the telnet session and before the actual disconnect is forced they could IP spoof the box and cause a DOS.
I say boulderdash but without any proof I am forced to create a bunch of ACL's to specifically deny telnet. Here is an example of my VTY's:
line vty 0 4
access-class 23 in
exec-timeout 30 0
password 7 xxxxxxxxxxxxx
logging synchronous
transport preferred ssh
transport input ssh
transport output ssh
*The access list here is limiting access from a certain internal set of IP's.
Any thoughts?

Marcos,
Thank you for your time on this. I believe I have found and corrected my issue. In my first post I showed what the vty 0 4 sessions were set as. What I failed to show was that the "vty 5 15" sessions were only set to "no exec". So what was happening is that when I would telnet to the router, the session attempt would either walk down the list of VTY sessions looking for an open port or the router just bypassed the ones that were set for SSH and tried the first VTY port that was set for no exec. This would allow for the telnet session to attempt to open but because the router was not allowing access to the command line interpreter, the router would reject the session attempt.
To correct this I simply set up all of my VTY sessions the same way, transport SSH in & transport SSH out. The next attempt closed the telnet session immediately. I still maintain there is no need for additional access-lists as I'm trying to keep my processor's free from any additional load to allow them to process the payload traffic as efficiently as possible.
If anyone has any best practices they would care to leave here, I would be interested.

Setting for transport request organizer

Hi all,
Can anybody tell me how to i get transport organizer every time when ever i will change the objects in sap bi.
Regards
Mohan

Hi,
There are two global settings done for transport management. Std and non-std settings. You can do this from Transport connection tool, Edit menu --> transport --> Standard on / Standard off.
If Standard is ON: You would be asked to save in a request what ever you do in the system like creating objects, etc.
If Standard is OFF: When you create objects, those would be, by default, stored as local objects. You will not be prompted to enter a transport number. You would need to collect objects from transport connection tool and move the objects to other environments. Once an object is assigned to a transportable package, whenever you do a change, you would now be prompted to enter a transport number eventhoug the std is off.

Does Firefox offer a timer that I can set for every 30 minutes?

I need to take a short break every 30 minutes. Can I set this up through Firefox? I am told that this is available for newer computers. Mine is about 4 years old.

How to generate a new rhread for every request

Hello,
I'm trying to write a server side program that does the following, recieves a Single connection from a client, client sends a request to the server side program, the server side program sends to a third party(back end) and waits for a reply.
The problem i am facing is the following, I want to for each message(request) recieved from the Client to generate a new thread and establish a new connection with the third party, I have tried creating a new thread for the communication with the third party, in this case if the response from backend takes time I will still be able to recieve other requests from the client. But I dont know how to return the message that his been to the Father thread. The reason why I am doing this is that I dont want the same thread that recieves the request from client to wait until the reply for the previous thread is sent.
Here's the code which I have been trying to implement.
ClientCommunicator {
Socket soc= new Socket(IPAddress,port);
Thread backEndComm= new Thread (new BackEndCommunicator
(soc,"Message To Back End"));
backEndComm.setPriority(8);
backEndComm.start();
public class BackEndCommunicator implements Runnable
Socket socket;
String messageToBeSentToBE= "";
public BackEndCommunicator(Socket socket, String messageTOBE)
this.socket= socket;
messageToBeSentToBE= messageTOBE;
public void run()
PrintWriter outtBackEnd= null;
BufferedReader innBackEnd= null;
String replyFromBE= "";
try
outtBackEnd= new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
outtBackEnd.println(messageToBeSentToBE);
outtBackEnd.flush();
innBackEnd= new BufferedReader(new InputStreamReader(socket.getInputStream()));
replyFromBE= innBackEnd.readLine();
How can I return the String "replyFromBE" to the ClientCommunicator class so it can be sent to the client as soon as recieved from the back end.
regards,
[email protected]

I assume the problem you are having is that your ClientCommunicator thread is blocking in a read and has no way of receiving notification from the other thread. Seems like you have a couple options at least.
1. Use non-blocking IO and a selector to do service both the client socket and the backend socket. Usually, NIO is more of a pain than it is worth unless you need to service hundreds of connections at once, but I think that in this case where you know that there are only two connections it might be easy enough to use.
2. A second option would be to avoid blocking on the read by using the available method on the input stream to first determine if you can actually read anything. This would allow you to wait with a small timeout on a monitor that the backend communicator could notify when it receives a response. This is not the ideal solution because you are limiting how fast you respond to the client and could be using more cpu time than necessary. However, it might be a lot easier to implement and could be adequate for what you need.
First solution is more elegant but potentially not worth the trouble. Second solution is less elegant, but may be good enough.

How to make setting for overlapping request-DTP

Hi,
I am creating a PC which is for monthly data and the cube in question is loaded twice as per the requirement in a month..
Now, i need to delete the same month data request when loading for the second time and rest all other previous month requests should not be touched...
For that, in the delete overlapping request variant i had selected ( in deletion selection ) only the option request date in current month...
and in the selection same or more comprehensive...
is it the rigjht selections to delete the requests of the same month? or is there any thing that i overlooked?

Hi,
Please go through this article...
I have clearly explained the concept with a scenario.

Infopackage setting for retaining request for year cross overs

Hi
Following is the scenario:
I have two loads(flat files), one for monthly and one for YTD. The YTD files has to be replaced and the monthly files have to be retained. While this can be acheived using the settings in the infopackage, Problem arises when the year changes.
For E.g, from Jan2007 to Dec 2007 the YTD files would be replaced and monthly files will be maintained.
In jan 2008, when we load the YTD file(for Jan 2008), the last YTD file for year 2007 will be replaces, there by replacing the data for the year 2007.
Im figuring out how to handle this situation for year change.
your inputs would be appreciated
regds
JPJP

Hi JP,
U can create a ABAP Routine of the type 6 (ABAP Routine),The field you are trying to populate is a select-option so you have to define the YTD from SY_DATUM.
the start date is 01JANYYYY, System will calculate YYYY from the current date.

Losing portelt session after every request

Using bwa wl portal server 8.1 on wxp sp2
Hello all
We wrote some JSR 168 compliant portlets and deployed them accoring to the bea doc. Basically our portlets seem to work. However, there are some issues that could be tracked down to one problem:
Somehow the session gets lost on every request! One action request uses the same portlet session during action/render cycle, but two consecutive calls to the same portal page yield different sessions, so holding any session variables is next to useless.
The deployment szenario is this:
Using bea workshop i created an application and deployed our complete jsr168 portal application. Since bea does not enforce a login/does not impose any login restrictions, i created another application which imported a second portal project, which used the first application as a wsrp portlet provider.
The second application merily consists of a web.xml containing only security restrictions:
<web-app id="WebApp">
<display-name>Livelink Portal Integration Kit</display-name>
<security-constraint>
<web-resource-collection>
<web-resource-name>Portal</web-resource-name>
<description>Security constraint for the whole portal</description>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<description>all users</description>
<role-name>Users</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>default</realm-name>
</login-config>
<security-role>
<role-name>Users</role-name>
</security-role>
</web-app>
At first i tried to add these security restrictions to the wsrp application but then the wsrp provider could not be reached so i split the applications.
So - how do i prevent bea from created a bunch of sessions? What am i doing wrong?

Hi
In server.xml, do you have cookies=true for both contexts (and the defaultContext)? I'm not sure how it would behave if one context was true and the other false.
Alternatively, could it have something to do with the crossContext attribute?
