While installing the J2EE agents you might see the Invalid Administration Server IP address error, even if the IP address of the Administration Console is valid. This error could be appearing because of the following reasons:
Enter the following command to verify the version of JRE being used by the J2EE Installer:
java -version
The J2EE installer should be run with Java 1.5 or later. To fix the problem, download and Install JRE 1.5. Set the PATH environment variable to point to the bin directory of the newly installed JRE.
For example, to set the PATH environment:
In Linux or UNIX: export PATH = <JREDirectory>/bin:$PATH
In Windows: set PATH = <JREDirectory>/bin;%PATH%
Run the J2EE installer.
Do the following:
The installation directory of the administration console must be reachable by the LDAP.
Check if the Firewall blocks the ports. If yes, release the port.
Check if eDirectory is running.
Check if the administration console is installed properly.
