jDeveloper display driver crashes while Scrolling - Display driver stopped responding and has recovered

If your display driver crashes while scrolling in jDeveloper and you get the message saying "Display driver stopped responding and has recovered" then this is the thread for you.

This can be fixed by modifying jdev.conf file. This file can be found at $JDEV_HOME/jdev/bin/jdev.conf or jdevbin\jdev\bin

Close jDeveloper. Make a backup of this file somewhere. Now go to the original file and add this line at the end of file:

AddVMOption -Dsun.java2d.noddraw=true

Save the file. Now start your jDeveloper (it may take 2-3 minutes for the first start after this). Scrolling should be fixed now.

If for some reason your jDeveloper does not starts then replace the original file back in jDeveloper.

'import' is not recognized as an internal or external command

This error might come up when you are trying to deploy an OAF pages and using the import command to import page files.
This error is coming up because in your environment variables you have not setup the path variable.
Location of import utility: C:\<JDeveloper-Installed-location>\jdevbin\oaext\bin
You can either include this in you path variable or just execute this in CMD:
cd C:\<JDeveloper-Installed-location>\jdevbin\oaext\bin
and then execute your import command.

Note: Using first method you will never have to worry about this problem again, but if you use second method, you need to do it every time you are importing a page.
