Does PLX file have any compiled code

Question

What exactly is a plx file. I created a plx file giving the COMPILE_ALL option as
NO. I saved the plx and the pll in the libraries directory .
When i run my form i can see the changes. Does the plx have any code or is it just
a referece to the pll file.
thanks

Answer 1

the point with the security is a good point. I appended it in my blog:
our projects are normally applications for customers and never standard-software. So we have no problem with security. The application server with the deployed forms and libraries is secured as strong as the database, so that only admins have access.
### this is added in the blog - try the example on your machine ###
Other developer say: plx is only the compiled code, so nobody can steal my sourcecode or something valuable from within the code - in that case try this example:
Create a library with a package and this variable:
<pre>
PACKAGE Const IS
HiddenPW CONSTANT Varchar2 (100) := 'HiddenPW';
END Const;
</pre>
Generate the plx and open it in an editor. Search for "HiddenPW". You'll find the name of the variable and the string associated to the var. That's not save in my eyes. Only the sourcecode is hidden. I think, that a pll on an Application Server is secure enough.
If the application is standard software and is not for free, then you can use the plx-technique :-)
