You need to download a separate install binary - you cannot use the JBoss install binary for WebLogic.
Please go through the following documents first:
- Preparing to Install Guide (single server) : http://help.adobe.com/en_US/livecycle/9.0/prepareinstallsingle.pdf
- Preparing to Install Guide (cluster) :http://help.adobe.com/en_US/livecycle/9.0/prepareinstallcluster.pdf
- WebLogic Install Guide : http://help.adobe.com/en_US/livecycle/9.0/install_weblogic.pdf
The LiveCycle Product Blog also will help:
I've found the download page and seen the files are over 2 GB.
Does the file include Weblogic or will it install on an environment where Weblogic should already be installed?
The file does not include WebLogic. Adobe expects WEbLogic to be already installed and configured. The same applies to the database also.
