Re: failed to open database channel. Check your connection dictionary, and ensure your database is correctly configured.

Hi Robert,

I long ago tired of playing this game with EOF.  Go here:

http://www.apress.com/book/bookDisplay.html?bID=248

Get the source code for our book (see sig).  Extract the file  
EOFJDBCConnectionAnalyzer.java and add it to your application.   
Create an instance in your Application constructor like this:

new EOFJDBCConnectionAnalyzer("modelName");

It won't fix the problem but it can determine the cause of the vast  
majority of them and suggest solutions.
