How to disable weblogic built-in HTTP session filter?

Hi,
I want to use my own HTTP seesion filter to manage HTTP session on weblogic clustered servers. It seems that weblogic servers plugin its HTTP session filter already for servlet. How can I use my own HTTP session filter to replace WebLogic built-in session filter?
Thank you for your help.

Could you be more elaborate on your requirement.
Weblogic servers plugin provides a way to handle requests based on url content. or content type and so on, it dosent do much with users sessions other than for session stickyness.

How to disable logon with token when session times out.

Please help!!!,
After I modified, save and close the web.config file and restart IIS, it continues to send me to the logon page after the session times out.
Is there other way that i can disable the logon after the session times out?
modified code:

<add key="logonTokenEnabled" value="false"/>
CRS version: Crystal Server XI R2 SP2
Viewer: .NET Infoview
Thank you,
Chico

I think if you enable some type of SSO (single sign-on) you could accomplish something like this, but with traditional logons this would be a security risk. You would need to allow your sessions to not time out. After a session times out with out some type of SSO involved it's impossible for our application to identify who the user is when they access an object. This is why you are reprompted for logon.
There may be a way to extend session life indefinitely but it wouldn't be recommended.

How to disable browser back button after session logout..

Hi;
I want to restrict the user to use the back button after session expired or logout. By doing the session expired we are restricting the user to do any new work but I want to restrict the user to see the back pages that he surfed previously in the session.
Is there any method to disable the browser back button after the session Expired?
please help me to find out the solution..
Thanks in advance.
With Regards,
Haramohan

One possible way is automatic return to the current page by writing the following Javascript code to the previous page:
<script language=JavaScript>
function backButtonOverride(){
setTimeout("backButtonOverrideBody()", 1);
function backButtonOverrideBody(){
try {
history.forward();
} catch (e) {}
setTimeout("backButtonOverrideBody()", 100);
</script>
<%
catch(Exception e){
%>
<jsp:forward page="front.jsp"></jsp:forward>

How to close a HTTP session when a user closes the window

Hi,
I am having problems when closing the browser of a BW web report. After I closed the browser by going File->close, I ran SM04 and found out the Plugin HTTP session hangs at the server side.
How can we terminate the Plugin HTTP session at the server side when user closes the internet browser?
I did implement a logoff function at my web template and this was implimented on the Menu page, if user clicks on the logoff, the Plugin HTTP session is terminated at server side correctly.
If user navigates to the other pages from the main page... then the logoff function was not implimented in the other pages. So many of the users are closing the windows directly. Eevn if we impliment logoff in all the subpages, As you know, 50% of time user will close the report by closing the internet browser instead of clicking the logoff. That leaves lots of hanging Plugin HTTP sessions at our server side.
Regards,
Tony

Hi,
And also take a look on the Genral property of the web template. We solved this problem by changing only this property (no extra things).
<b>Property: Value</b>
Automatic Session Management: Active

How to find the list of users loggin through HTTP session

Hi All,
we are using SRM 5.5 system with ITS. I am able to find the list of concurrent users from ABAP level using report "CCUEVAL" but how do I know the list of concurrent users logged in from HTTP session?.
could you please let us know the SAP note number or any report?
Thanks in advance,
Mohan Karri

Hi Uday,
thank you very much for your prompt response.
I need a report because by end of every month I would need the average peak http users list for the reporting month.
or tell me how to find " how many users logged in through HTTP session in a day?"
Thanks

By the way, we actived our BEX service at the SICF.
Thanks for help!
JA

Hi
If you want to avoid a blank page with logoff button, add opener=0
<a href="<SAP_BW_URL CMD='LOG_OFF' ~command='logoff'
>" onClick="javascript:window.close(opener=0);">Log off</a>
If you want to close the session via X, use this code:
create a sapscript function
function closeSession()
logoff()
window.unload=CloseSession()
However, the Plugin HTTP session isn't killed.

How to disable sessions in CS6?

InDesign Server CS6 added a mechanic of multi-threading jobs via sessions.
Now you can begin session and end session via SOAP web service call.
However, the sessions add a huge overhead for those who want to use multi-instance instead of multi-threading.
A webservice call without a session ID is always ~500ms slower while it creates a session in the background. The session is then appears to be used on a ~5 second sliding timeout allowing subsequent calls to be 500ms faster, however if you wait around 10 seconds, the next call recreates the session and increases render time by ~500ms again.
This is a major issue when rendering takes on average of 1000ms. That's a 50% longer execution time. This is a major problem when trying to offer a speedy web application built on top of IDS.
I tried creating sessions and keeping the IDs in memory, but they expire and result in a whole bunch of SOAP errors.
My question is: Is it possible to disable sessions in IDS CS6 or remove the session expiration time completely?

This is the other discussion: http://forums.adobe.com/message/4518765#4518765
I've tried to lower the quality, and with pure magic, it now works, even when I put highest quality. I don't understand what happened. I asked you how to disable openGL because they told me to in the last discussion. So, thank you for repairing my problem (I think you repaired it, i'll make tests to see). Just in case, could you verify if it's posible to disable openGL like the other person told me?

How to lookup a EJB 3.0 session bean which is deployed in WebLogic 10.3

Now Jdeveloper 11.1.1, is giving WebLogic server 10.3.
With internal WebLogic server, when I created a Sample client, it generated code as:
private static Context getInitialContext() throws NamingException {
    Hashtable env = new Hashtable();
    // WebLogic Server 10.x connection details
    env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
    env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101");
    return new InitialContext( env );
public static void main(String [] args) {
    try {
        final Context context = getInitialContext();
        DefaultSession defaultSession = (DefaultSession)context.lookup("property-DefaultSession#com.vs.property.model.session.DefaultSession");
    } catch (Exception ex) {
}How to update the above code to lookup the EJB 3.0 session beans with an external WebLogic server 10.3?
Is there any documentation available on how to install weblogic, troubleshoot, debug, WebLogic server 10.3?

-raju

Raju,
Hi, to start, here is a tutorial on a quickstart web application using an EJB 3.0 stateless session bean that fronts a container managed EclipseLink JPA entity manager on WebLogic 10.3, you will find references there to other general WebLogic documentation.
[http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial]
using @EJB injection on the client instead of a JNDI lookup as below
[http://edocs.bea.com/wls/docs103/ejb30/annotations.html#wp1417411]
1) in your second env.put I noticed that your t3 port is 7101, I usually use the default 7001 - but It looks like this port is valid for the JDeveloper embedded version of WebLogic server runs - just verify that it matches the port of your server.
2) your name#qualified-name lookup looks ok. Verify that the jndi-name element is set in your weblogic-ejb-jar.xml for non injection clients like the following
<weblogic-ejb-jar>
<weblogic-enterprise-bean>
<ejb-name>ApplicationService</ejb-name>
<jndi-name>ApplicationService</jndi-name>
3) as a test outside of your application - launch the WebLogic admin console and goto the testing tab of your bean in [Home > Summary of Deployments > "application" > "session bean name"

How can I flag HTTP session attributes to not be replicated ?

          WLS 5.1 SP8 - In memory replication of a stateful servlet. Is
          there any way to flag data that has been, or is being, loaded into
          a HTTP session so as to not be replicated ? It's a long story,
          but we have some data loaded into a hashtable, more specifically
          a Properties object, stored in our session. With the hastable
          already loaded into the HTTP session, weblogic does not detect
          when we add values to the table, and therefore does not replicate
          the changes. Which is ok since WLS is working as designed. To
          get around this we load the hashtable back into the session everytime
          we add a value to the hashtable. Yup, I know that's ugly. Anyway,
          what I'm trying to find out if is there is an attribute that we
          can set to indicate, to not replicate this data or that data.
          Something along the lines of a attribute on a per hastable value
          basis. For example, I load value A into my hashtable, then I
          need to put my hashtable into the session to get it replicated.
          Next I load value B into the hastable, and again to get it replicated
          I have to load the entire hashtable back into the session. The
          problem here is that the entire table gets replciated. Does anyone
          know if I can set an attribute on value A, when I'm adding value
          B, so as to not replicate value A when I reload the table ? Of
          course all goal is to not store so much data in the session, but
          I'm trying to find a work around until that is completed.
          Thanks,
          David


          Where can I find documentation on the details of how Weblogic decides what will
          be replicated in the HTTPSession object (for example, it only replicates attributes
          which are set or updated using "setAttribute()"?

Weblogic HTTP Sessions timeouts

Hi All,
Im quite new to Weblogic 8.1 and am having a problem with HTTP sessions. I have two applications (lets say App1 and App2) in the same Weblogic server, and want to pass information from App1 to App2. Because of HTTP ServletContext rules, I cannot pass session information from one context to another. So instead, when App1 passes information to App2, I create a new session in App2 straight away. When the session timesout, it will redirect me to a page. This redirect will only be done when the user clicks a button (server side redirect rather than a client side automatic redirect). This is all working fine except I hit this problem.
I have set the timeout interval to 1min (in web.xml) for testing. After I wait 1 min, I click the button and it redirects - Ok thats cool. The real problem is that I wait for the session to timeout after 1 min. Then I wait for an extra 2 mins on top of that (so in theory, the session should still be timed out). When I click the button again, the session is created again rather than redirecting. Now I find this odd. It seems like Weblogic is recreating the session (as I get new session ids).
Has anyone come across this before and does anyone know how to get around this? Is it some configuration in Weblogic that I need to setup?
Regards,
Andy

If your applications exchange data extensively, you may want to consider
merging them into a single application. If it is not possible, you should follow
the standard approaches used to connect standalone, remotely located
applications. The range of possible design solutions is pretty wide - web
services, EJB, CORBA, etc.

How to disable PDF.js built in viewer for my site

On my site PDF files are used for printing purposes. Starting with v19 visitors start start to claim that this functionality is not working any more. The cause of this is the new built in PDF viewer. It doesn't open print dialog after pdf file download if the the file is built to doing this. Also I’ve found that the quality of printing via the built in viewer is unacceptable. The content is distorted by the JPEG compression and additional headers and footers are present on the page. So for my site built in PDF viewer should be disabled at all. I've found no way to do this at the site level. I think that the instructions for disabling the new feature is too complex for ordinary users and it easier to ask them to use another browser.
I think that should be an option at the site level to disable the built in PDF viewer. At least this option should force the browser to ask the user that for working properly with this site the built in PDF viewer should be disabled. And if user choose to disable it this should be done in one click.

@john99,
FF19 ignores your "Application preferences", described in [[https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file]]
and
[[https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-without-downloading-them]]
as long as pdf.js is enabled. This is counter-intuitive and user-unfriendly. One shouldn't have to override settings (disable pdf.js) in about:config for an option configurable in the regular GUI to work as expected.
