Apache2.x and Tomcat5.0.x & Session' data

hi everyone,
i was just wondering how i can pass user's session data from Apache to Tomcat and visversa:
an examples
im restricting access to a directory secret/* with Apache Authentication on Mysql (AAOM)
Inside that directory ther is a link to one of my servlets
what i want is to pass the user's data already collected after the log in against AAOM (username, etc ...) to that servlet
ill be glade for any ideas how i can perform this
ps im using mod_jk which mean im using tomcat only as a servlet container behind apache since the most data iam serving is a static data
Thanks in Advance

Hi,
I believe that this must have been discussed somewhere but as you are saying that you could not get clear answers, please find the answers.
In 3.x, we had Infopackages loading the data to infoproviders. In the infopackage itself, there was an option which asked you the way to update. i.e. Only to PSA, To PSA and subsequently to infoproviders, To infoproviders only. Thus, PSA was optional.
In 7.x, PSA are mandatory and Infopackages can load the data only to PSA. DTP loads the data from PSA to infoproviders.
DTP also provides many new options to us in BI. e.g. You can carry out delta load from PSA to infoprovider.

Shared Session Data

Hello Everyone,
I have a problem that I could not seem to find a solution or best methods and practices for.
I have session level data abstracted by a package API and accessed query-inline via a table function. All this works fine; however, there is one caveat that does not. The query SQL is passed to a jobs table and executed by a scheduled job. So the job session can not see the user session data.
Is there a way to:
1) Share Session data?
2) define a table as containing Session temporary data, but public scope?
3) Group Sessions or grant session privileges (to share scope)?
4) Run a process/job under a different Session ID, or with specific Session privileges?
5) Call a procedure or function from one session, but have it Execute under a different session?
As it stands, I can either copy the data out to a permanent table (and manually implement Session ID, and Session level cleanup), change the current API and underlying global temporary table to a permanent table (and again manually implement Session ID, and Session level cleanup), or before job scheduling parse the SQL, and expand the function table data into the SQL statically.
None of these are solutions I like. I am looking for something more elegant. Any suggestions would be appreciated.
*EDIT: sorry, I forgot to add; I'm using Oracle 10g.
Thank you for your time.

As a job is a brand new session that is created to execute the supplied PL/SQL code. This process does not create the session by inheriting the environment (name space details, temp tables, transactions) of the session that submitted the job.
Imagine the complexities of this when the session that created the job, terminated 24 hours ago.... would it session state (if kept persistent) still apply? And what about the complexities dealing with the overheads to somehow and somewhere store this session data for the job to re-use.
Nope.. this is not a workable solution (and nor a sensible one), so Oracle does not support it. When a job is executed, a brand new session is created for that job. (not entirely correct at a technical level as the job queue process may already exist and already have a session - but conceptually, think of a brand new session for a job).
Is there a way to:
1) Share Session data?What session data specifically? And what about a session that long since ceased to exist? What about session data that is dynamic and changing? Should then job see the version of that data at the time it was submiited? At the time is started execution? Or the data as it is currently within that session?
2) define a table as containing Session temporary data, but public scope?Does not need to have a "public scope". It can be managed via an API (PL/SQL), using the job number as unique reference number. It is even possible to create low level access control on such a table that only the job and no-one else can even see the data in that table, except for the job.
3) Group Sessions or grant session privileges (to share scope)?Nope.
4) Run a process/job under a different Session ID, or with specific Session privileges?Which session privileges? Remember that each session has two basic memory areas - the PGA (Process Global Area) and UGA (User Global Area). Both are private and non-sharable.
5) Call a procedure or function from one session, but have it Execute under a different session?Nope.
As it stands, I can either copy the data out to a permanent table (and manually implement Session ID, and Session level cleanup), change the current API and underlying global temporary table to a permanent table (and again manually implement Session ID, and Session level cleanup), or before job scheduling parse the SQL, and expand the function table data into the SQL statically.Still not sure what you imply with session data.
In my case I have a process API (running on top of DBMS_JOB ) that developers use to schedule jobs (it manages external processes, mostly used for collecting data from other non-db servers). In some cases, the caller is a Virtual Private Database (VPDB) session - with a name space that contains the keys and tokens and what not that is required for access control and security. The name space cannot be copied across to the job.
So as part of the process API that creates the job, a logon/authentication/authorisation call is added. With the calling session username. This is the same call that would have been made when the user session was created at logon time. And this call creates the name space that contains the keys and tokens required. Thus creating that batch (job) session in the background, uses the same initialisation processing that an interactive session (created from the app server) would use. The code running in that job is oblivious to the fact that the session was not created via an interactive logon from the app server.
None of these are solutions I like. I am looking for something more elegant. Any suggestions would be appreciated.If you truly want an IPC mechanism between two sessions in Oracle, two methods come to mind. Database pipes. Advance Queuing.
This is not really that complex to implement. IPC itself is not difficult. The difficult part is designing the code around cross-session communication and have that work effectively and efficiently. And within the database session context, this can be not only quite difficult to do, but also not always the very sensible thing to do.

Waveburner; a few Questions regarding track files and Session Data

After a bit of negotiating, I'm almost ready to burn. Was having problems with file locations and discovered that i had multiple files in different locations. Those have been eliminated and all relative track files are in one place now with the Song Data File as well.
I then re-imported the individual aif tracks only to find that all of my fades and edits are GONE. It appears that I may have to DO THEM ALL OVER AGAIN! Please tell me that there is a work around.
Is it possible to import only the Session Data related to the fades and edits(everything but the actual audio files), so as to avoid all this "do-again" work?
I was also wonder if it is necessary, or perhaps a good idea, to change the File INFO for each of the individual audio track files from "OpenWith" iTunes (default setting) to "Open With": WAVEBURNER ?. (selectable on the aiff files, "Show More Info" window
Currently the aif files are set to "OpenWith" iTunes (default)
One last question please.
Is Waveburner really up to snuff? How many people are using this for Mastering and Burning CD's? I'm about to start inserting some AU Mastering Plug Ins and I'm hoping for the best. Any other suggestions are greatly appreciated.
G5 Dual 2.0/PBook G41.5Ghz/LogicPro7 Live5 Reason3.0 PansncDA7 TascamFW1804 Mac OS X (10.4.7)

You're grammer isn't bad jord, it was I who asked a plethora of questions under one Subject heading.
When i open the project file(.wb3),
The prompt says;
"Please choose a replacement from the list below:"
/Volumes/320GB HD/Users/ahuihou/.Trash/1 Track 01.aiff
/Volumes/320GB HD/Users/ahuihou/.Trash/2 Track 02.aiff
/Volumes/320GB HD/Users/ahuihou/.Trash/3 Track 03.aiff
/Volumes/320GB HD/Users/ahuihou/.Trash/4 Track 04.aiff
/Volumes/320GB HD/Users/ahuihou/.Trash/6 Track 06.aiff
As you can see the files are in the trash.
The first problem is that there are no actual files in the trash. Just an icon of a CD Disc which was dragged there to eject it, It is no longer in the disc drive/tray. Perhaps i should put the disc back in the drive and then update/replace the files afterwords. (The CD is scratched.)
The strange thing is that i can still preview the track that's in the trash by selecting More Info and playing it on the little Quicktime player bar. I guess the file is in a cache somewhere?
I've looked everywhere on all drives for the specific files but can not find them anywhere.
In the Replacement prompt there is a place that I can check to "Search in the same folder for subsequent files" button on the "Replacement" prompt.
which "same folder" is it refering to?
The Trash folder where the old files are or the Folder where the actual .wb3 project file is? I do have all of the correctly named song files/regions in the same folder with the project file.
maybe i should just start again. i'm not one to give up easy though and would much prefer to "beat" the computer at the game.

How can I get Firefox to "grab onto" and then "hold onto" the data signal until I tell Firefox to release it at the end of my session of internet browsing?

ok, I hope that my description of this problem does not come out in such a disorganized fashion that it makes the description difficult to follow. here goes: every 30 seconds to 1 minute (or thereabouts, I'm estimating) my mobile phone's browser (whether Firefox or any other) loses the data signal, so that tje next time that. I click on something, I get an error message that the "data connection timed out, retry" or "network unavailable" or "check that you are connected to that internet", etc. etc. etc. I have downloaded many apps that are supposed to boost data connectivity and/or improve internet speed, blah, blah, blah, till I discovered that was a problem with the server being able to keep up with staying locked onto my browser. in one of these apps diagnostic screens, I found a notation that therr was something wrong with my cell's relative position. well, how could that be, I wondered, since I had "GPS tracking" "GPS reporting" and "location sharing" all enabled? but, then I noticed, on the image of my cell's location as represented by this particular app, that every half minute, or so, the blue dot which represented my cell's location would slip to the left about one quarter of an inch, or so, and in the longitude and latitude part of this app's diagnostic screen I saw that the numerical designations of my cell's longitude and latitude were zero and zero. it suddenly occurred to me that the server had lost sight of my cell because my cell had moved too far out of the range of that server's sight due to the rotation of the earth. well, blow me down, what am I supposed to do to fix that? how can I tell my cell phone's OS to send out some kind of identifying info on a constant basis, so that the server could keep track of it (and I would not lose the signal)? or, conversely, how could I get my cell phone's browser to grab onto the signal and not let go of it until I was done with that internet session, at which time I would then manually release the signal myself? I hope that my explanation of the problem made enough sense that you could follow it and that you can come up with a workable solution for me. oh yeah, my phone is an LG OPTIMUS ELITE 696. thanx, from the enragedkangaroo.

Hello,
I'm afraid I don't think there is going to be much we can do to help you here. The description sounds like an issue with the phone rather than with Firefox specifically.
I don't think the problem can be caused by you moving out of range of the cell, due to the rotation of the earth. The cell towers (that provide phone signal) are sitting on the earth, just like you, and so move at the same speed as you. This might be a concern with satellite phones using Low Earth Obit satellites but this isn't the case here.
I think the best thing to do would be to get in touch with your Phone Operator or Device Manufacturer for support. If you are out of the support period or can't get support from them for some other reason then a standard 'cure-all' for mobile phones is to do a Factory Reset. This will return your phone to its default factory settings and wipe all of your data / modifications off the phone. This tends to solve most problems and is probably what the official support team would tell you to do. I can't guarantee that it will help but it has a good chance.
There are instructions on resetting your phone here:
http://www.hard-reset.com/lg-optimus-elite-hard-reset.html
I hope that helps.

Session data not carried over. with IE6SP1 and WL7

Hi,
We recently upgraded our clustered WL to WL7x and after that we started seeing
a strange problem regarding session data of our HTML/Servlet pages.
When we access the pages through this cluster, the session data(browser cookies
not accepted) is not carried forward in IE6 SP1. With IE5x it works fine. The
Local Intranet is always coming as blocked for the cookies. I am not able to reset
the settings also.
The same set of programs are working fine with server running WL5x.
Is it anything due to P3P or is there any setting I should do at WL7 level for
this problem? When I do the URL rewriting this works fine but, as many are static
HTMLs submitting servlet request, we are not able to do URL rewriting.
Any help on this will be highly appreciated.
Thanks
kavitha

It doesn't seem to be a problem with serializable attributes though.
Also Weblogic doesn't use the distributable tag. So that should
not matter too.
Can you investigate further and try to pinpoint the issue?
When we access the pages through this cluster, the session data(browser
cookies not accepted) is not carried forward in IE6 SP1What do you mean by session data not carried forward?

How the hell does a person share session data between JSP page and a Servle

1. How the hell does one share session data between a servlet and a JSP page without using a bean but rather using a normal string variable.
2. When using session scope to access a bean the application complains about not finding the bean on the specified scope, however when I use an application scope the save the same bean, the application does find it.
Please help!!!!!!!
SERVLET:
HttpSession session = request.getSession(true);
ServletContext servletContext = session.getServletContext();
customerID = result.getString("CustomerID");
userName = result.getString("UserName");
session.setAttribute("UserName",userName);
session.setAttribute("CustomerID",customerID);
System.out.println("Customer UserName = " + session.getAttribute("UserName"));
response.sendRedirect("/economics/subscriptions/default.jsp");
JSP PAGE:
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root xmlns:jsp=http://java.sun.com/JSP/Page mlns:c="http://java.sun.com/jsp/jstl/core" xmlns:sql="http://java.sun.com/jsp/jstl/sql" version="2.0">
<jsp:directive.page isThreadSafe="true" session="true" contentType="text/xml"/><jsp:output omit-xml-declaration="false"/><jsp:scriptlet>response.addHeader("x-xslt-nocache", "true");</jsp:scriptlet><pml>
<page type="web" search="y">
     <pageName>Commercial Banking</pageName>
     <jsp:directive.include file="/economics/header.inc"/>
     <jsp:directive.include file="/login.inc"/>
     <jsp:directive.include file="/economics/leftMenu.inc"/>
     
     <content>
     <searchSum>Commercial - Main Content</searchSum>
     Value = <c:out value="${request.session.getAttribute("UserName")}"/>
     </content>
     <jsp:directive.include file="/economics/rightNav.inc"/>
     <jsp:directive.include file="/footer.inc"/>
</page></pml></jsp:root>

For a start, just "session" instead of "request.session" would work better. But why did you post this here and not in the JSP forum? Doesn't seem to have anything to do with Java programming.

I am posting data for va01 and va02 using BDC session,what happens if

Hi,
I am posting some data for va01 and va02 using BDC session,but what happens if i try to post same data using call transaction.

Hi,
That is just another method. You can post the data using Call Transaction as well.
Just give it a try and in case you face some problem revert back with your issue.
We will help you to solve the same.
Hope this helps!!!

Is there any facility to store session data temporarily and use it for Calc

Hi
I would like to know is there any facility to store session data temporarily and that can use it for calculation int BI Beans.
ANy idea or thoguhts would be appreciable .
Thanks n Advance
Anwar

One way to do is to create a temporary variables in the AW and store values in these variables. Not sure if it fits on what you are doing. You can always store data on the BIBeans Applications layer. Not sure what your use-case is.

How do I access session data through an EJB?

Hi
How do I access session data through an EJB?
I am currantly developing a Web service (using ejb's, JBoss.net and Apache Axis). A client making a call to this Web service, is expecting a bussiness-object in return. My problem is that this bussiness-object i stored in a users session data. How do I retrieve this bussiness-object from the users session.
I have read that this does not work with httpsessions, is this true? If this is true, is it possible to store the bussiness object in a JavaBean e.g:
<jsp:useBean id="userContextWebImpl" scope="session" class="com.ac.march.client.UserContextWebImpl">
<%
String key = "test";
String value = "This is the value";
userContextWebImpl.setValue( key, value1 );
%>
</jsp:useBean>
and then retrieve this information through the EJB? Or is it possible to do this by using Statfull JavaBeans? Or can this be done through a nother solution?
Please help!

I have created a JavaBean with scope="application" to store some data. The data is stored when a user prefomes a spesific task.
A different person then makes a call to a Web-Service on the server. The Web-Service then asks an EJB to retrieve the data stored in the JavaBean (servlet cotext). In other words: How do I retrieve this data from the EJB?
I have tried with this code, but with no luck.
(ApplicationContextWebImpl is the JavaBean)
public static String getBookingResult( String key )
     String myResult = null;
     String myKey = key;
     ApplicationContextWebImpl applicationContextWebImpl = null;
     try
          applicationContextWebImpl = new ApplicationContextWebImpl();
          myResult = (String)applicationContextWebImpl.getValue( key );
     catch ( java.rmi.RemoteException e )
     return myResult;
}

How can we reset the session data in SAP ISA B2B application.

com.sap.isa.isacore.action.IsaCoreInitAction$StartupParameter this action class providing the special feature to store all data passed to it in the request as parameters into the session context and make them available for all other actions.
1. But in the inner class they had defined private parametrized constructor.
2. Action class is defined as final.(there is no chance to override the method)
3. There is no setter method (only getter() is available).
4. Creating a new Z_ class that is reflecting in entire application.
5.They had hard coded the Session attribute name in Action class.
6. Application is expecting a session object with the same attributes.
Is there any chance to create a new object for this class or any where any chance to reset the session data. Am using the Multiple_SoldTO concept in my application. My back end ECC .Please help me.
Advanced Thanks

I am not sure about your requirement, but yet.. Did you check UserSessionData object? It encompasses all the session variables.

Could not deserialize session data, java.io.InvalidClassException

Whenever I click on logout link from Liferay(Which deployed as application on Weblogic 10.3),It shows below Exception in the console however i am able to logout sucessfully.
Could not deserialize session data.

It seems to be Classpath polluted with different hibernate jars.But still not able to figure it out.Below is the jar files which i have in classpath.
hibernate-annotations.jar
hibernate-commons-annotations.jar
hibernate-core.jar

Application Server: Weblogic 10.3
Any Help would be much appreciated.

Sounds like you have two different versions of a class in the two applications.
If you change a class implementation and recompile - the updated class gets a new UID. Looks like maybe one app has a jar with the older class and the other app has a jar with the new class.

How to replicate session data at the user level?

Hi all,
my client has users who use laptop/tablet computers in the field with wireless connections. The application requires the users to complete long multi-page forms where the data is only submitted to the EIS layer at the end of the process. The connections regularly drop out which understandably is a cause of some grief. In addition, the users want to be able to switch to another machine in order to complete their session.
The 'switching machine' requirement kills the idea of using persistent cookies and session replication unfortunately. So I am faced with the idea of storing the session data (keyed by user id), in serialized form, either on a stand-alone disk which is accessible by each webserver in the cluster or is the database. The problem with the database idea is the performance hit of traversing the EJB and JDBC layers.
Can anyone suggest the best practice in this case? Or point to an article or tool that covers the problem?
BTW, the app serves a small (<50) and stable base of authenticated users so scalability is not really an issue whereas failover is.
Regards,
Dave.

There are a number of timeouts in SSRS; session timeout, report execution timeouts, http request timeouts. A session timeout in SSRS is not the same as a session timeout in ASP.NET. Below are some articles that can help you understand the timeouts
and hopefully lead you down the path of discovery.
This articles is a good article as it discusses the session timeout and the keep alive that is sent from the report viewer.
http://blogs.msdn.com/b/jgalla/archive/2006/10/11/session-timeout-during-execution.aspx
This article is good as well in describing some of the timeouts.

session!ReportServer_0-6!4b0!03/18/2015-10:51:29:: i INFO: LoadSnapshot: Item with session: fnxgxhjuveugvd552qfyv3fw, reportPath: , userName: doman/user not found in the database
Any ideas how this can be resolved?

Hi Nasa1999,
Based on your error message, If the all the users will sometimes got the same issue, it can be caused by the timeout issue. It happens a lot when rendering big report, and it exceeds the default Session Timeout. You can execute script
to increase the Session Timeout time. Please refer to following blog:
Session Timeout during execution. Also increase the value of <Query Timeout> in rsreportserver.config file. This file locate at XX:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer
Please also check to set the <legacyImpersonationPolicy> back to true(https://support.microsoft.com/en-us/kb/972328).
Locate the Aspnet.config file in the following folder:
%windir%\Microsoft.NET\Framework64\v2.0.50727
If Microsoft Visual Studio is installed on the computer that is running SQL Server 2005, double-click
Aspnet.config. If Visual Studio is not installed on the computer, follow these steps:
        a. Right-click Aspnet.config, point to
Open with, and then click Choose program.
        b. In the Programs list, click
Notepad, and then click OK.
Locate the following tag in the <runtime> section of the code.
        <legacyImpersonationPolicy enabled="false"/>
Change the tag to:
        <legacyImpersonationPolicy enabled="true"/>
Save the Aspnet.config file.
Reset IIS.
Try your report again.
