I'm getting an error message on applet startup: "the reverse lookup is not properly setup. Please read the installation instructions for further information"

Java has many security features built in to insure that applets can do no harm to the environment that they are running in. One security threat is "dns spoofing". An Applet is only allowed to open connections to the server from which it is loaded. JWebEdixx loads its configuration file by opening a connection to the server. The host name is checked on opening the connection and to make a "dns spoofing" attack impossible a reverse lookup is also performed.

What is a reverse lookup? Most of the time the name service converts a host name into an IP, i.e. www.jwebedixx.com converts to 212.87.154.3. A reverse lookup converts an IP into a host name, i.e. 212.87.154.3 converts to www.jwebedixx.com.

You can check if the reverse lookup is working by doing a nslookup with the IP of the host on which JWebEdixx is installed. If the reverse lookup is not set up on starting JWebEdixx, an error message is displayed. There are two possibilities to configure the reverse lookup.

1. The system administrator has to set up the name server with the reverse lookup records for the host on which JWebEdixx is installed.

2. The host is added to the hosts file on the client. On Windows this would be the file: C:\WIN2000\system32\drivers\etc\hosts. Adding a line "ip.ip.ip.ip hostname" would make the reverse lookup possible (ip.ip.ip.ip is the IP of the host on which JWebEdixx is installed).

Does JWebEdixx run with Java 1.3 our earlier versions?

no. We have decided to use the best, fastest and most secure Java version available at the moment: 1.4.0. We recommend using java 1.4.1, the applet startup speed has been vastly improved in this version.

Java 1.3 had a few bugs that interfered with the development of this applet. *Maybe* there will be a future 1.3 version.

The Microsoft virtual machine is based on a over 5 year old java version, 1.1.8! This VM has severe security holes (Microsofts posting here).

Does JWebEdixx run on MacOS 9?

no. MacOs 9 has been official put to rest by Apple even though many users still rely on it. There will be no 1.3 or 1.4 Java VM developed, so there will be no JWebEdixx support for this operating system.
