I am using virtual box configuration for this that Jim M put together.
I have everything installed and am trying to practice somethings. The first first thing is App Engine. So I created some new fields and the a table to update so I would not affect any of the PS tables. Then I created a simple App Engine program that just updates a field on the table using the SQL action with continue if no rows. I ran the program it finished ok but no update. I changed it to abort if no rows and it aborted. So I took the same code and ran through sql developer and there was an update.
So what I did then was changed the table to one that PS delivered and that was updated.
I am signed on in 2-tier to the data base I don't think I need to sign on the app server do I?
Just wanted to you an update after doing some more tests I created a page to insert data. Well something strange happens now when I run the app engine. The rows that were inserted using sql developer the rows were not changed but the rows I entered online were changed. So there is nothing wrong with the app engine.
Do you know if some parameter on sql developer has to be changed. using version 1.5.5.
