jDeveloper - In a real Pickle??? Help

BenClark asked
Medium Priority
Last Modified: 2012-06-21
I have just inherited a web app that was written jDeveloper 10.
I have the source code and the jDeveloper IDE.
How do get started? I know the app compiles into ear files, but how do I setup
the app in the IDE and debug it?

Any help or suggestions would be greatly appreciated.

Watch Question

Hi Ben,

Questions   ???

Have you tried to put it into an IDE that you are using? And what problems are you experiencing?

Can you show the program here if it is not too long or can you give a  URL so as to be able to download it for study ?

Also, what is the meaning of  " into ear files" written above?



I tried loading it into the jDeveloper IDE.
It wants a startup file. I don't know which file that would be.
The entry point on the web server is the Index.html file. jDeveloper won't let
me pick that as a startup file.

The web site is an internal site for the company so I can't give you a URL.

When the old programmers were done with changes, they would compile the code
and jDeveloper would produce a .ear file. This file is placed on the Unix web server.
Thats all I know about it.

What I need to know is,
1. What would typcially be a startup file? I am asuming this would be a java script????
2. Is there something particular in a startup file that I can look for to identify the startup file?
3. Any other info that could possibly help me get started.


Hi Ben,

I know how frustrating things can be.  Really!!

Here is sources for your Q's  for "what does this mean? ".

option 1.

look at Java definitions: 0-9 A......Z

Take your time and browse around in the Java alphabetical listing of terms. I went to  "S" for startup.    It should put you on the correct track.

You can write the Roedy for further comments.


Option 2.

register (it's free) and then search for "Startup file"
a lot more to read.....


Hi Ben,

Have you had any progress on your search for a Startup file?





Without revealing what the program is (because it is not possible according to you),  show a list of errors that are shown when you attempt to compile the program,  then,  when you attempt to run the program. The entire list from each listing would be appreciated.



This is what i get when i try to compile.

Hi Ben,

Let me take a few very long guesses. You need a password to access this program.  The data files are still on the website.  It can't find a work space.

My advice is to find the original author,  make suitable requests to access the program and permissions to change it.

That said, I am at a loss to recreate this startup file.  

I therefore request that you ask "community support" at EE here to close this particular Q and refund you your points completely. I cannot help you.
