How to solve an error in connection to the Oracle database with powerdesigner15

Today, a table is designed in powerdesigner15, and you want to connect to Oracle through powerdesigner, and then generate the table directly in the database. Set the connection options according to the methods provided on the Internet, and click the test button. The connection is always unsuccessful. The error message is: Non.
SQL error: cocould not load class. After checking the information on the Internet, I found that there was a problem with the powerdesigner15 design. This problem has something to do with the Oracle driver jar package. The solution is as follows:

1. Place the Oracle driver jar package ojdbc14.jar to the installation directory of powerdesigner15;

2. re-edit the connection configuration and select the jar package under the installation directory;

3. Restart powerdesigner15.

Note: When setting system environment variables, We will write at the very beginning ".; ", this ".; "indicates the current directory. Therefore, you can find the Oracle driver jar package in the powerdesigner15 installation directory.

The end!
