Info*Engine JAR Files and Property ZIP File Creation
The client-side installer requires a number of corresponding Info*Engine JAR and property files, which must be present in the following ZIP file:
$WT_HOME/bin/Infoengine/IeAdapter.zip
If the IeAdapter.zip file exists already then it must be recreated manually by a Windchill administrator. To recreate this zip file use the following procedure:
1. Open a Windchill shell.
2. Navigate to the following directory:
$WT_HOME/bin/infoengine
3. Run the following command:
ant -f PackageAdapter.xml package_files
The zip file IeAdapter.zip is created under the WT_HOME/temp/ie_adapter_install directory. This file must be unzipped on the client Allegro Design Workbench Library machine during the installation of Windchill Gateway for Cadence Allegro Design Workbench.
