Can we save context in a HTTP session?

When the servlet invokes and ejb, it needs a context to get a home interface. Can i create the context once and save it in the HTTP session. And can i reuse this context for all subsequent ejb calls for the same user.
Thanks in advance,

Dear Faraz,
Not sure.
But one workaround could be to store the variables temporary on a KM document.
I once saw this solution on a client. (it stored simple variables such as flags, numbers, etc...)
It was for temporary variables and it did the job pretty well.
Maybe could be an alternative for what you're looking for.
Kind Regards

Https session lifetime

How can lifetime of a secure session be controlled in OC4J 9.0.3-9.0.4?
Is "session-timeout" parameter in web.xml valid or is the SSL session controlled by other parameters?
We are migrating to https an application that worked properly in http mode, and sessions expire now after just a few seconds. We can't find where to config https session timeout. OC4J documentation is very vague regarding to secure applications.
Thanks,
Modulab Team

Having the same problem for more than 1 week, couldn't find a solution. Session expires in a very short time in https. We're using standalone OC4J (9.0.3). Do I have to change it with AS now ? Isn't there any other solution, patch or something like that ?
Any kind of your help would be greatly appreciated since thousands of WEB users of our institution CAN NOT use all of our https WEB apps.

How can I save a session to another hard drive or flash drive?

I want to rebuild my hard drive but I want to save the Firefox session (like 70 tabs) before I do so I can reload them after the rebuild. Can I save a session to another hard drive or flash drive?

The data of the current session is stored in the sessionstore.js file in the profile folder.

I recently start using Firefox panorama. If I create a tab group that contains, for example, my favorite stack exchange websites, can I save ("bookmark") this tab group for easy access if I start a new session?

I recently start using Firefox panorama. If I create a tab group that contains, for example, my favorite stack exchange websites, can I save ("bookmark") this tab group for easy access if I start a new session?

You can bookmark all those tabs and place them in a folder.
* "Bookmark This Page" and "Bookmark All Tabs" no longer show in the Bookmarks menu unless you open the Bookmarks menu via the keyboard (Alt + B).
* "Bookmark All Tabs" can be accessed via the right-click context menu of a tab on the tab bar.

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()"?

Can't save non http bookmarks in firefox

Can't save non http bookmarks in firefox
Amongst standard website favourites saved on my IE toolbar i have several html documents/pages of my own making. These obviously begin with a non-http address.
Examples are pages that contain an array of favourite webcams on a single page, or a page that opens up several related sports sites each in their own tab, or a stormchasing swathe of tabbed windows covering live video chase, weather radar, emergency service scanners etc. etc.
An address would take the format on the lines of
"C:\Documents and Settings\USERNAME\My Documents\Football Results and Tables\UK.html"
Firefox insists on adding 'http' before the C:\ (plus unlike IE it also adds the %20 for spaces.)
Can anyone help to to get FF to accept a favourite that is not a website.

I just verified that it still works for me in Firefox 18.0, using the "star" in the Location Bar.

Web contexts and http session

Mark Kipperman

Yeah, if this is the way it's supposed to work its a useless and, dare I say, stupid "feature". Wouldn't the whole point of this be to have quick access to groups of pages. If I have to select them each time to create the group what is it doing for me?

I can't save and open .ai files.

Hello.
I can't save and open the file with special character in virtual drive(using communications). -> refer to this.. ( http://software.naver.com/software/summary.nhn?softwareId=MFS_105031 )
*Special character I used is 黒(not 黑).
If I rename the file name(黒.ai -> test.ai), the file is opend successfully.
And when I save the file as "Illustrator ver.8 format", the file is saved well.
This is the error message I have.

- save : The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder.

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''

Forms6i Accessing HTTP Session Object in APache JServ

I want to create an HTTP session object via a servlet in Apache JServ. This session object contains user profile data as well as session context information. The servlet will redirect the user to the forms6i listener servlet. Can the Forms servlet access the session object and retrieve/modify its values? Does Forms6i provide APIs to do this natively?

Maybe the Java Importer is what you are looking for.
You can use it to call the servlet from within forms and get the information you need.(But only after forms is running).
look at the Java integration section on Forms section of otn.

Webvpn - can't save changes to applications

Hi,
I have Cisco 1940 router with IOS version 15.0(1)M4. I have configured WebVPN for access to my internal applications.
From Chrome and Mozilla I can login to webvpn portal and than to applications, but I can't save changes (input) to applications .
In IE application is not displayed at all, I get blank page.
Also, some images in application are not loaded.
I think that there is a problem with webvpn java script, which doesn't terminate lines with ";".

I believe it's more a Leopard and permissions thing than iPhoto. Did you upgrade to leopard via the Archive and Install method? Try running ACL Fix on the iPhoto Library package and see if that makes a difference.
Secondly, create a new test library inside the Shared folder and import some photos into it and see if it will operate OK. If it does you can use the paid version of iPhoto Library Manager to merge the old library into the new one and use it.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Where can i save the use's data of external application?

where can i save the use's data of external application?and whether will it accumulate to some synchronic problem?
The way i am doing by is to save the information in providersession by initSession() of ProviderInstance,then to get the information back by using session.getAttribute(),which is in jsp. is it right?and what problem will be caused?
so i want to know what is the standard method to use the information in external application to page.

Hi Alf,
Please have a look at the POINT portlets. most of them are based on external apps. That could give you a fair enough idea of how to go about with your designs.

You can use:

You can set the warn prefs on the about:config page to true via the right-click context menu or toggle with a double left-click.

Hello ryane84
The easiest and most efficient way to copy your music is to follow the steps under the External drive section. Make sure that you have organized the iTunes library first before you copy it over. Then put the copied iTunes folder in the same Music folder on your computer.
