If you encounter problems, you can download Java free from Sun Microsystems. The URL is:

Note:As of this writing, to get the plug-in, you must download the entire Java Run Time Environment, which is greater than 5 MB. Netscape version 6.1 for Windows appears to support the Merkato Java applications, but it is not fully tested for Merkato version 2.1. Merkato supports all versions of Internet Explorer. Likewise, the Java 1.4.1 plug-in for Macintosh OS X appears to work as well, but is not fully tested for Merkato version 2.1.
