Installation fails on 64–bit systems that have 64–bit JDK because the installer tries to use the 64–bit JDK.
If you are installing Application Server on a 64–bit system, download the 32–bit JDK and use it to install Application Server on your 64–bit machine. You will need to use the following command:
./distribution_filename –javahome path-to–32bit-JDK-location
After installation, to ensure that Enterprise Server uses a 64–bit JDK, edit the value of the AS_JAVA variable in the asenv.conf file to point to the 64–bit JDK installation.
