Applet Security and Web Servers

843807Sep 17 2002 — edited Sep 25 2002
Hi,

I know that applets cannot read or write to the client's file system and cannot communicate with any network server other than the server from where the applet code is served.

My question is that given these security measures, is it possible to have an applet read the contents of a directory on the web server, and display this list of files in a browser window on a client machine?

I am doing this is Java 1.1 (so my users won't have to use the Java plug-in).

I don't think this should be a big deal, since the web server is where the Java code origianlly exists, and applets are not restricted from commimicating with their web servers.

Thanks,

Steve Cromer

It looks like table TEST1 is being used as a temp table.
In Forms, this should probably have been a GTT.
GTTs don't work in APEX dye to Connection Pooling. You'd use a Collection instead.
But, I'm just guessing about the purpose of TEST1.
(PS - you should probably have just done an INSERT... SELECT instead of parsing a cursor in a loop)

Dear Mike Kutz
I want to delete all the old records from test1. then i want to update the table with the latest Query data from test table. can you suggest how to insert the records using the procedure in Oracle Apex .
Delete all Data from A Table
Query on Table B and get the data
Insert the Query data into A Table.

APEX is stateless. It automatically calls COMMIT as needed (or ROLLBACK ).
I'd keep it simple, Sanjay (K.I.S.S.)

BEGIN
  DELETE FROM TEST1;

  INSERT INTO TEST1 (empno,name)
    SELECT empno, name FROM EMPLOYEE;
END;

As you are running this from a Dynamic Action it will be running in a different database session to that of your page. If your page hasn't committed it's data, the session in your DA will not see that data.
Is there a particular reason you are doing this work through a DA and not through a process?
