Create the file associations
Open Windows Explorer and click Tools Folder options File Types, or the Internet browser used, for example, Edit Preferences Helper applications, and verify the following: file type .jlnp is associated with the jawaws application fil t i i i t d ith th Cit i ICA Cli t E i file type .ica is associated with the Citrix ICA Client Engine
If the associations have not been made, create them in the following way: To create the associations in Windows-based NetAct user workstations, select New/New Type. Note: To create the associations in Windows-based NetAct user workstations you can use, for
l Wi d E l I t t E lexample, Windows Explorer or Internet Explorer. Follow the steps below to create the file associations in Linux-based NetAct user workstations: Start the web browser you want to use. Select Preferences/Options Select Helper Applications/Application/File Types Add the MIME type application/x-java-jnlp-file for files with extension/suffix .jnlp and add as the application that the browser should invoke for this file type /opt/Nokia/j2re1.4.2_12/javaws/javaws. Add the MIME type application/x-ica for files with extension/suffix .ica and add as the application that the browser should invoke for this file type /opt/Nokia/ICAClient/wfica shthat the browser should invoke for this file type /opt/Nokia/ICAClient/wfica.sh .
