I deployed caArray 2.2.1 in eclipse and tried to test the program. When I clicked on the "Manage array design" , I got exceptions. The first part of the exceptions was like these:

answer}}Answer:{{answerEnd
This type of the exception could be caused by an empty caArray schema. User should verify if caArray schema has been setup properly by:

  1. Opening the caArray database to see if the tables have been installed.
  2. Querying a known caArray table in MySQL Client, see example below:

    SELECT * FROM category

    If the schema is indeed empty, it can be reinstalled via the steps below:

*1. * Shut down the caArray JBoss server

*2. *Run the following ant command from the software/build folder:

ant database:reinitialize
*3. * Restart caArray JBoss
