jsp - How to clean session attribute from all active session in java? -

-

Currently I'm working on a web project which uses JSP / Sarlet and Strat Framework. We are using the cache mechanism. I want to clear some session attributes from all active sessions on special sessions (for example, in case of fresh cache). So what is the best way to apply the same?

You must provide a class that applies (part of the server API) interface and it's web Register in .xml

Then you can track active sessions and use that information to gain access to the session and update the attribute. Effectively the implementation class will be a singleton, so you have to deal with synchronization problems carefully during session tracking

Of course if you have a cluster environment with multiple nodes, the promotion of feature changes is quite complex Could.

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
