If your MINERVA "does not work", here is a set of hints to check.

Remember that in order develop and run any Web-hosted service with MINERVA your need an operational chain of:

  • Server Side:
    • MINERVA object files
    • http demon
    • TCP/IP networking
  • "The Network"
    • HTTP protocol enabled
    • Java allowed
    • Proxy servers running depending on your network layout
  • Client Side:
    • Java Browser
    • TCP/IP networking

To develop MINERVA programs, you will additionally need

  • A Java Language processor capable of handling Java 1.1

You see that there are a lot of things that can go wrong. Fortunately most of them are quite simple.

The Most Frequent Culprits are:

  • Server side
    • no http demon installed
    • Http demon installed but not running
  • Client side
    • Browser dies frequently
    • Java in Browser available but not enabled
    • Browser cache not cleared, old files clog its mind
  • Network side
    • too slow, causes timeouts. Frequent with large corporate or academic networks which work fine internally but have only a ridiculously thin wire to the outside
    • Firewall does not allow Java class files
    • Proxy server setup incorrect
    • address resolution does not work

A few general rules:

  • do only one thing at a time
  • check components independently
  • cross-check with other components
  • read the error messages
  • read the documentation
  • ask a friend (including your MINERVA sales partner!)
