Data Source Connection Fails After Installing to a New Directory

Problem: After uninstalling Sybase Unwired Platform, then installing to a new directory, a data source connection fails in Unwired WorkSpace, with the message: java.lang.ClassNotFoundException: com.sybase.jdbc3.jdbc.SybDriver.

Explanation: This may happen if you use an old workspace, and an old JDBC connection profile with its jconn3.jar pointing to the old directory.

Solution:

  1. Once Sybase Unwired WorkSpace is installed, switch to a new workspace directory.
  2. Or, manually change the driver path by modifying the properties of the connection profile for a New Driver Definition.
