I remove nbuser32/ and my netbeans install install netbeans 3.2.1 fomr scratch start netbeans, setup using defaults goto update center update all packages (include db -- database explorer) netbeans restarts as usual goto runtime panel, database explorer, click on drivers node, i get a list of driver templates etc. ^^^ all of the above is normal. Then I proceed to install the postgresql jdbc jar I quit netbeans cd ~/lib/netbeans/lib/ext ln -s /usr/share/pgsql/jdbc7.1-1.2.jar jdbc7.1-1.2.jar then restart netbeans... then I get the exception (attached) I am using: $ rpm -q redhat-release jdk postgresql postgresql-jdbc redhat-release-7.1-1 jdk-1.3.1-fcs postgresql-7.1.2-5PGDG postgresql-jdbc-7.1.2-5PGDG
Created attachment 2678 [details] ide.log detailing the unexpected exception
I think the problem is that your are using a link to the JDBC driver jar insteand of the real driver jar and the security manager doesn't allow you to load the classes from the linked jar. Copy the driver to the lib/ext directory and it should work.
Closing as WORKSFORME. (for more info see the previous comment)
VERIFIED
Resolved for 3.3.x or earlier, no new info since then -> closing.
