Error "Driver class not found" when accessing MySQL: Solution? How to specify new java driver?

pstein-JavaNetSep 19 2018 — edited Sep 22 2018

I retieved an older backup from end of 2016 from my archive disk with SQL Developer v4.1.5 to access local MySQL Database v5.7.22 on 64bit Win 7 with installed 32 bit Java v1.8.0_181. MySQL and Java was NOT part of this backup archive file.

When I started this older SQL Developer I got an error popup:

"An error was encountered performing the requested operation:

Driver class not found

Verify your Driver location"

So I guess SQL Developer missed a newer MySQL java jdbc driver which matches the (meanwhile installed newer Java or MySQL).

Due to some reasons I don't want to use SQL Developer v18.2 yet.

So I must fix it for SQL developer v4.1.5

How do I get a newer, corresponding java driver for Java v1.8.0_181 and MySQL v5.7.22 and specify it in SQL Developer v4.1.5?

Check out Preferences, Shortcut Keys. For Mac, it looks like this:

It appears that <ALT>[ and <ALT>] are defined by default. (pressing <ALT> "either square bracket" will toggle between opening and closing bracket pair).

You have to have the cursor right next to a bracket for it to match its paired bracket.

Redefining one or other to <ALT>5 will kind of mimic vi, except it is <ALT>5 instead of vi's <SHIFT>5 (%).

Note: <ALT>5 may already be defined and this will override that.
