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!)
