after (clean) installing SQLDev 3.2, I'm unable to add third-party drivers in the automated way (from Tools/Prefs/Ext/Check for up):
- tried (multiple times) with MSS and MySQL drivers,
- pop-up window (licenc-agrement) appears and
- nothing else happens.
Checking the <profile>\SqlDev mappa shows a dir named "temp\update" has just created and it contains the expected files (eg. oracle.sqldeveloper.thirdparty.drivers.sqlserver.58.17.zip) with 0 bytes.
The first thing that comes to mind in this case is a problem on the update centers, or some kind of firewall issue; but in your case there is also JDK 1.7 wich is currently not supported and has been reported to cause various issues, so before checking anything else I'd try to install and configure the latest JDK 1.6 and try again.
I guess there is some problems with the update center: drivers also cannot be installed with JDK 1.6.37 and other extensions install normally.
SQLDev works quite well with JDK1.7 (at least, I didn't find any "big" errors, some minor bugs are out there, of course),
moreover, it works also with MySQL-connector-5.1.22 :) - even though it's stated in the Rel.notes: "Do not use the latest MySQL driver 5.1. Use the 5.0.x drivers for MySQL."
And to confirm, you have this workikng with the new SQLDeveloper 3.2.20.09.87 just released? I had it working in prior version but cannot get it to connect with this latest version. Thanks in advance for your time.
