PB2019R3, b2703
Window 10, 64 bit platform, VM


What is the way to integrate JDBC into the Database Painter?

We have installed Zulu Java, it's our replacement for Sun Java --> Oracle Java --> no longer free.
We have instaledd EBD PostgreSQL as our new database.
I just installed the EDB JDBC driver, then added the location of the JAR file to the PATH. I also created a CLASSPATH = jar file path,

Opened PB and expanded the JDBC section. Nada.

This is a list of our PostgreSQL databases using an ODBC driver.


   I kind of expected to see a JDBC administrator, like the ODBC administrator, but apparently that's not a real tool.  :(

   Anyway, I want to open the PostGresql databases using the JDBC driver inside the PB DB Painter in order to do some performance testing/comparisons. How do I do this?


Thank You,
Olan

Hi Olan,

DON'T !

Appeon is dropping all support for JDBC connections in the (soon) coming release.

Here's some extra information:

- Did you install the Zulu Java 32 bit driver?

- Did you add the necessary information in the Java tabpage within "Tools > System Options"?

For Postgres I recommend to use ODBC for two reasons: 1) ODBC is the officially supported interface to Postgres, and 2) Java support has been discontinued in PB 2022 and newer.

Wow! Thanks for the info, Armeen.

May I ask why we would drop support for JDBC?



Thanks,

Not much demand for Java features. Upkeep is extremely expensive with all the security problems.

Actually that's a very valid point Armeen.
