File Association - Override Oracle JRE settings

[c.sottile]

Hi all,

Does OWS unattended installation allows to override "file association" settings of a previous Oracle JRE installation?

If this is not possible, what other alternatives can be considered?

Thank you,
Carmelo

On windows, if you had .jnlp file extension associated with Oracle JWS then the following Registry entry would exist:

Code: Select all

Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.jnlp\UserChoice

The above key will have attribute ProgId pointing to ProgId of Oracle JWS exe, for example, JNLPFile defined as Computer\HKEY_CLASSES_ROOT\JNLPFile

When you double-clk on a .jnlp file Oracle JWS is started.

When you run OWS's Unattended Installer. it will remove the above mentioned UserChoice key from the registry.

Now when you double-clk on a .jnlp, it will ask you to choose a program. You can choose OWS Launcher an choose "Always use this app to open .jnlp" to associate .jnlp with OWS:

Hi,
thank you for the explanations provided. They have been very helpful.

I take this opportunity to ask you a couple of questions:

1. There is any way to impose OWS File Association to all users during the installation phase starting from the response? Without the user having to choose it?
   At the moment our response.var file contains the following configuration:

   Code: Select all

   sys.fileAssociation.extensions$StringArray="jnlp","jnlpx"

2. It is possible to increase "unattended installation mode" verbosity logging?

Thank you,
Carmelo

OWS's Unattended Installer will make the file association but (as far as I know and tried) it will not override the existing UserChoice in the registry.
