Java session is not working in browser sometimes

Hi,
In some PC, sometimes session is not working properly in browser.
In JSP, I am creating the session like below
session = request.getSession(true);
session.putValue("loginid",login);
But in next page, it is showing null value.
I have checked the browser setting... cookies are enabled... everything is ok in browser setting..
In our company, this issue is coming in some of PC not all in all the PC
If we format the harddisk & again reinstall the OS, it starts working.
Anyone can pls help me on this?. This is very urgent.
Regards
Selva

As of Version 2.2 putValue(java.lang.String name,
java.lang.Object value) has been deprecated.
Use session.setAttribute("loginid",login) instead of putValue()

Button not working in browser

I am coding a video player in Netbeans 6.8. just find two problems:
1. the browser button not working in browser when I run the project from Netbeans under "run in browser" mode. however under "standard execution" mode, everything is fine.
2. can not run the jar file in the project's dist directory directly. in other word, I can not run the jar file outside of Netbeans.
I appreciate any help. thanks.

thanks for your reply but I need more specific operation.
maybe I am not very clear about the problem one. I mean when I run the code in standard mode, if I click the browse button, a window will pop out and I can choose a video file from my local harddisk. but if I run it in "web start execution" mode and "run in browser" mode. the browse button make no response when I click it.

E72 - Ctrl+C and Ctrl+V not working in browser

yesterday i updated my nokia e72 mobile to latest firmware 31 , after that Ctrl+C and Ctrl+V and Ctrl+A shortcut keys are not working in browser. which have made me feel as bad as typing the same text again and again (usfel in blogging or web messaging).
ALthough these shortcut keys are working in notes and sms application, but not in browser and Quick office applications (word, ecxel etc).
Can some one tell , how to fix it. or do i need to wait for next firware update. firmware 31 was released on 31 of march 2010. and today is 26th of May. almost two months have passed, and nokia has not yet released patch for this bug ....
Nokia, how long i need to wait ?, for this bug fix release.

(Had to edit because didn't read previous post clearly.)
I originally thought this was a problem of Quick office 6.2.217 Nokia_S603.2. I think it is a Nokia firmware problem as the previous post had stated.

Reopen All Windows from Last Session is not working

The option Reopen All Windows from Last Session is not working, is there any other way to recover the tabs from my last session?
Last night I fell asleep and my friend shut down my laptop.
When I woke up in the morning I couldn't restore my last session which had several tabs opened for my research.
I don't know the exact date when I found them, so I haven't been able to find them in History either.
I've looked around on the internet, but haven't been able to find anything that helped me out.
Hope you can help me! Thanks.

Restart your Mac.
Check the box for: Reopen windows when logging back in
Then check History > Reopen Windows from Last Session

Could not find an installed JDK, SCM Java Tools may not work until registry

Hello all,
I've downloaded the latest full version of Designer (10.1.2.3), but getting installation error: Could not find an installed JDK, SCM Java Tools may not work until registry
Any solution?

3. install the Designer 10.1.2.3 patch to the Developer suite home.When I try to do this at C:\oracle\product\Ora10gDSR2, I get a message OUI-10137: An Oracle Home with name OUIHome already exits at C:\OraHome (a directory that doesn't exist) please specify another name for Oracle Home.
I don't want to just specify another name because cleaning up these faulty installations requires deleting registry keys, etc, since the deinstall does't really remove everything sufficiently to start with a clean slate.
I also got the Java JDK message because the JDK 5 is no longer being put straight onto the C drive, it is buried in C:\Sun\SDK\jdk, so some java programs have to be pointed to it. The Oracle installer doesn't provide this option.
Also, Michael, your post, "Re: Designer 10.1.2.3 on windows Xp Posted: Oct 20, 2007 7:05 AM in response to: mmehdi" is full of unreadable characters and question marks. Maybe I don't have a font you are using. There are also references to a zip file and a Word document that aren't there.
Anyway, thanks for all your time and effort,
Edward

Your question doesn't make much sense, so this is a WAG. Launch the Java Preferences.app in /Utilities, install the Java Runtime Environment when prompted, and, when that's finished, enable Java and Web Start apps.

Tomcat 5.5.26 Sessions getting replicated but not working via browser

Hi,
I have configured Tomcat 5.5.26 to be clustered across 2 machines with one instance on each. These two machines are behing a BIG-IP loadbalancer which is setup for sticky sessions.
The catalina.out states that the member can see each other:
Jul 3, 2008 6:33:50 PM org.apache.catalina.cluster.tcp.SimpleTcpCluster memberAdded
INFO: Replication member added:org.apache.catalina.cluster.mcast.McastMember[tcp://10.17.21.125:9001,catalina,10.17.21.125,9001, alive=38753]
Jul 3, 2008 6:33:51 PM org.apache.catalina.cluster.mcast.McastService registerMBean
The localhost.2008-07-03.log states that the sessions are being replicated for the jsp-examples app - book example. I have an app of our own that does not even state that the session is replicated but I though I would start here with getting the example one working.
Jul 3, 2008 6:34:31 PM org.apache.catalina.core.ApplicationContext log
INFO: SessionListener: sessionDestroyed('E7E9E54600927A4826AFEDB59D7EF6E7.tomcatDargle')
However, when I take down the instance which created the session and attempt to refresh the page or navigate to another page I get page cannot be displayed. This shows that the sessions are not completely replicated. What am I missing?
I have added my server.xml file contents:
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
expireSessionsOnShutdown="false"
useDirtyFlag="false"

<Receiver

<Sender

<ClusterListener className="org.apache.catalina.cluster.session.ClusterSessionListener" />

</Cluster>
Any help at all would be greatly appreciated.

Hi Ganeshmb,
The app I am using is the jsp-examples/book example.
The load balancer is sending requests to both servers.
When the dargle instance is sent a request I can see in the logs of both servers:
INFO: SessionListener: sessionCreated('730F4AD5A21CA06639BF956B9F5418CB.tomcatDargle')
When the tolka instance is sent a request I can see in the logs of both servers:
INFO: SessionListener: sessionCreated('E7E9E54600927A4826AFEDB59D7EF6E7.tomcatTolka')
When the server starts up the relevant info is in the logs:
Jul 3, 2008 6:33:56 PM org.apache.catalina.cluster.session.DeltaManager start
INFO: Starting clustering manager at /jsp-examples
Jul 3, 2008 6:33:56 PM org.apache.catalina.cluster.session.DeltaManager getAllClusterSessions
WARNING: Manager [jsp-examples], requesting session state from org.apache.catalina.cluster.mcast.McastMember[tcp://10.17.21.125:9001,catalina
,10.17.21.125,9001, alive=44363]. This operation will timeout if no session state has been received within 60 seconds.
Jul 3, 2008 6:33:56 PM org.apache.catalina.cluster.session.DeltaManager waitForSendAllSessions
INFO: Manager [jsp-examples]; session state send at 7/3/08 6:33 PM received in 123 ms.
The jsp-examples book example is supposed to have serilizable object and was recommended on some sites are the way to test out the replication. Is there any other way to test this?
Also, the main purpose of the cluster is to replicate an application from an external vendor which they say is compatible with session replication. However, this app does not even output the sessionCreated message so I am unsure if it truly is compatible.
If I could prove that the cluster is setup correctly then I would have more to go on when contacting the vendor. At the moment I am unsure if the cluster is setup correctly for session replication.
Thanks,
Martin

AS Java sessions are not closed until they time out

Hello Experts,
we have a SAP PI system to integrate SAP R/3 with external applications and recently we are facing a problem with inactive sessions. There's a new application we are setting up that consumes a webservice published by this SAP PI system. The scenario is SOAP --> PI --> PROXY. What we have noticed is that when the application sends loads of requests sometimes the system fails. This is because we are reaching the maximum number of open sessions in AS Java (1000). Investigating a bit more we found out that the sessions are not "closed" once the communication between the application and SAP PI has finished. Those sessions are open until they are automatically timed-out by the system after 1800 sec.
We have found the notes below in SAPNet:
Note 1363751 - ICM: Java Web sessions are not terminated
Note 1307940 - New HTTP session opened for every web service call
However, none of them are applicable to our system because it is more updated:
SAP PI 7.1 EHP1 SP002
Kernel Patch Level: 87
We have tried to close connections from the application that consumes the webservice but with no success. The sessions remain in the server until they are timed-out. Could you please tell us if this is the normal behavior of an AS Java system? Is this the way it should work? If so, can you tell us how to decrease this timeout so the inactive sessions are cleaned faster? We tried to find it but we didn't manage. Is there any way to close the session once the communication has finished?
Thank you in advance.
Roger Allué i Vall

Hi Roger,
You can do the following things to help solving your issue:
1. Decrease session timeout default value of the web container: Use the NetWeaver Administrator
Open Application Modules plugin within NWA
Configuration Management -> Infrastructure -> Application Modules
Set the desired timeout web module you are using, in minutes.
The default value 0 in the NWA means that the value is not modified
and the default value of 30 minutes timeout will be used.
2. Increase the max. no. of Sessions in Configtool
The max. number of Sessions can be set in Configtool in the Expert
mode. There is no limitation for the parameter.
Thanks,
Anderson

Java Applet is not working in IE11 in win8/win 2008 server

Hi,
we have developed web application using PHP. in the start of the page we have link which will kick start the Java Applet application on click.
It is not working in IE 11 browser with all windows machine until we add that page in the compatibility view settings.
we have tried with many options like setting the meta tag in the start of the HTML page.
but this is also not helped. we expect some more idea/solution to solve this issue.
Thanks in Advance.
Thanks.

Applet with Image not working in Browser, works fine in Appletviewer

Hi,
I encountered a problem , running my Applet in a browser. (IE and Firefox, ame problem).
When I use an ImageIcon, it doesnot work. in a browser.(When I remove the icon, it's oke)
In Appletviewer it works fine. In the browser I first got a security-exception.
I dealed with that by signing the jar (with the test certificate).
Now the browser's java console is not showin any faults, but the applet is showing no picture at all.
Only the text of the label is shown.
Can someone help me?
I downgraded the class to a very simple form, shown underneath. This runs fine in Appletviewer, but not in a Browser.
Best Regards
Remco

I have recently had the same problem, after lots of searching, I found that only Java 1.1 is supported by browsers, leaving out everything else including swing. So if you cant play the applet through your browser you need to download the appropriate patch i think about 5mbs.
You should find one at java.sun.com/getjava/download.html
Mine worked fine afterwards

Java plugin is not working properly

I have FF 16.0.1 and Java plugin 7 u 9, this is not the java with security problems...
http://web.psjaisd.us/auston.cron/ABCronPortal/GeoGebraMenu/Investigating%20Parent%20FunctionsUsing%20GeoGebraGeoGebra%20is%20graphing.htm
loads very slowly or not at all, including the majority of the links on the page...this is a menu to multiple Java applets in GeoGebra. This page has a preload link which causes a problem. All links are java applets which until your security issues on Java were implements worked flawlessly and better than any other browser service...
You are forcing me to us IE, which I despise!
I cannot copy from crashing page...

So, you are having problems with Java 7 update 9 in Firefox? You said "until your security issues on Java were implements worked flawlessly and better than any other browser service..." I don't know what you mean. Java security updates are from java.com (Oracle) not Mozilla.
In case it helps, I downgraded from Java 7 to Java 6 awhile back for security reasons and I'm now running [http://java.com/en/download/manual_v6.jsp Java 6 Update 37], which is the latest Java 6 and has all current security patches. (I'll eventually switch back to Java 7 once Java 6 is no longer supported). Except for a few of the links loading slowly, I don't see any issues on the page you mentioned. Hopefully someone with Java 7 u9 will be along and test the links but you could try uninstalling Java 7 and installing Java 6. More on Java here:
*http://kb.mozillazine.org/Java
*[[Use the Java plugin to view interactive content on websites]]
You also said, "I cannot copy from crashing page". Is Firefox crashing? Do you have any recent crash reports?
#Enter about:crashes in the Firefox location bar (that's where you enter your website names) and press Enter. You should now see a list of submitted crash reports.
#Copy the most recent 5 report IDs that you see in the crash report window and paste them into your forum response.
More information and further troubleshooting steps can be found in the [[Firefox crashes]] article.
Also, Firefox 16.0 is not the current version and is insecure. See http://www.mozilla.org/security/known-vulnerabilities/firefox.html
Unless you have reasons for using an older version despite the vulnerabilities, you should [[update Firefox to the latest version]], currently 17.0.1.

Applet work well in appletviewer but do not work within browser

hi, i created an applet that works well in appletviewer,but it does not work within a firefox browser, it issue a message: java.security.AccessControlException: access denied (java.io.FilePermission imgDir/vsam.jpg read). What can i do to solve this issue please ?

sign the applet, use doprivileged and trust the applet when you open it.
Use htmlconverter in jdk/bin folder to convert you applet so it uses
object tag instead of applet so IE won't try to run it with msjvm.
Signing applets:

Some browser links not working - any browser, but just on my mac

I have a strange issue. Over the last while certain page links on browser pages (which seem to be Java script links) won't work in any of my 5 browsers. If I put the same page in to any of my laptop's or my wife's browsers, the links work fine.
For example, I just tried to order some stuff via Staples, and whenever I tried to go to the next screen via a button, nothing happened. Even if I switched User Agents in Safari or Firefox, the "next" button didn't work. Same in Chrome, Camino, Flock and Opera on the same pages. I have noticed lots of drop down menus are not working properly either on many sites.
I figure some bit of OS code must be either blocking or misreading the instruction, but what?
Any ideas? Any input would be greatly appreciated!!

errmm... i'm not sure why you are fiddling with java and system extensions...
java has nothing to do with javascript despite the name (you can blame sun for that) the javascript engine is an integral part of the browser not a separate extension.
Java on the other hand is an entirely separate entity and language that is independent of any one browser and is installed on the OS.
Javascript is commonly used in webpages (all most all these days) where as java is hardly used at all and is usually confined to little "applets" that run separately from the rest of the page.
If you suspect that it is something to do with your settings/preferences in your library then the easiest way to find out is by creating a new User account (go to system preferences> users> and add a user.) Then log into that account and try the browsers in there.
If you really think that it has something to do with system extensions then you can disable them by moving them out of the extensions directory (/System/Library/Extensions/) However i must stress that unless you know what you are doing and know what the extension does that you are moving to not do so... you can easily render your system unbootable if you move the wrong extension... unless you have installed a 3rd party system extension there shouldn't be anything in that directory that isn't meant to be there (this is a very different system from OS 9).
However there are internet plugins that may be interfering with your browsers, you can find these in /Library/Internet Plugins/ you can disable these by moving them also... the defaults are various flash, java, shockwave, quartz and quicktime files.
