PowerDesigner fails to connect to oracle and reports Connection Failed

Today, when you are going to export the table structure of the project through powerdesigner, after configuring the data connection parameters, click "Test Connection" and always report "Connection Failed". After searching on the Internet, I finally found a solution. The main problem is to choose the path of the JDBC driver jar files. The solution is roughly as follows:

1. Put the Oracle driver jar package ojdbc14.jar in the installation directory of PowerDesigner15;

2. Re-edit the connection configuration , select the jar package in the installation directory;

3. Restart PowerDesigner15.

Because we will write ".;" at the front when setting the system environment variables, this ".;" refers to the current directory, so the Oracle driver jar package can be found in the PowerDesigner15 installation directory.
