just guess where the welcome screen is coming from.
If you succeed in idenifying the locaion, you can have your own welcome screen every ime
you start JDeveloper, just by changing it.
Knowing the start-up flags/parameters
There are some flags that you can set to alter the launching behavior of the IDE. These are
set as the command-line opions for the shortcut that is used to launch the IDE.
JDeveloper is a muliuser-enabled IDE that allows muliple users to share the same
workstaion. By default, the IDE coniguraion iles are saved in a directory within the
user's working directory. The following are the start-up flags/parameters:
-J-Dide.user.dir=<system_directory> : Using this property, you can
override the default behavior to write the coniguraion iles into the speciic
directory of choice.
An alternate way for this is to set the JDEV_USER_DIR environment
variable that points to the user's current working directory.
JDEV_USER_HOME and JDEV_USER_DIR are the variables that are
listed in the MW_HOME/jdeveloper/jdev/bin/jdev.boot
file. JDeveloper will look up these variables on startup to set the user's
directory. For example:
set JDEV_USER_HOME=C:\Users\vtkrishn\AppData\
Roaming\JDeveloper
set JDEV_USER_DIR=C:\JDeveloper\mywork
nonag : This will disable all dialogs or messages displayed while staring the IDE.
However, the splash screen will sill be displayed to the user. Use nosplash to
disable the splash screen.
