UPDATE with alias - P6Spy on JDeveloper

Thanks Vadim, but I have another problem.

I can't install P6Spy on JDeveloper. I tried using the instructions, but
in the P6Spy READ file don't exist about JDeveloper.

I tried replacing, in the JDeveloper connections, the PostgreSQL driver
"org.postgresql.Driver" by "com.p6spy.engine.spy.P6SpyDriver", and then
configuring the "spy.properties" file with the correct realdriver, but I
get the following message:

-----

Anyone know this? :(
