I want to read an .exe file generated by a java application through C++ but i don't know the formate of that file. when i open the file in text editor i can't see anything but the symbols.
Can anyone out there tell me what will be the file formate of .exe generated by java application or any other way out

Which Java application are you talking about that generates exes?
Or do you mean .class files instead, and you want to "read them" from C++?

Now we're getting somewhere. Still, a .ssf file is not a .exe file. And there are several different meanings for .ssf, as a quick google tells us.
Anyway, iIf you developed this application I would expect you to know the format. If you are using some library to generate whatever these ssf's are, then I would expect the documentation for that library to describe it. Finally, if you have downloaded this application, I would again expect its documentation to describe the format.
You cannot expect anyone here to magically know the spec of some file format if you haven't even identified which one you mean.

Nooo thanks.
Let me tell u some functionality of this application as i only have the jar file of this project.
It is a graphical application just like MS Paint but it only draw text with different colors, change background color etc.
i also generate some code of this project through a tool which convert .jar file to java code.
As i don't know much about java so i can't able to understand completely this code.
I am copying the code of action lister of open file menu....
if (e.getSource() == openMenuItem) {
ExampleFileFilter ssfFilter
= new ExampleFileFilter("ssf", "Sedao Scene Format");
chooser.setFileFilter(ssfFilter);
if (System.getProperty("PROPERTY_APPLICATION_KEY")
== "qc2.jar") {
if (getApplicationMode() == 0) {
if (System.getProperty("PROPERTY_LAST_SCENE_DIR")
!= null)
chooser.setCurrentDirectory
(new File(System.getProperty
("PROPERTY_LAST_SCENE_DIR")));
if (chooser.showOpenDialog(this) == 0)
open(chooser.getSelectedFile(), false);
} else if (!((SchedulePanel) schedulePanel).openSchedule())
JOptionPane.showMessageDialog
(this,
"There was an error loading the schedule file. please check it is a valid schedule file.",
"Error Loding Schedule", 0);
} else if (System.getProperty("PROPERTY_APPLICATION_KEY")
== "Overlay.jar") {
if (getApplicationMode() == 0) {
int returnVal = chooser.showOpenDialog(this);
if (returnVal == 0)
open(chooser.getSelectedFile(), false);
} else if (getApplicationMode() == 1) {
boolean result
= ((SmartScheduleDesigner) schedulePanel)
.openSchedule();
if (!result)
JOptionPane.showMessageDialog
(this,
"There was an error loading the schedule file. please check it is a valid schedule file.",
"Error Loding Schedule", 0);
}
}
chooser.removeChoosableFileFilter(ssfFilter);
}
The fact that your java application produced a .ssf file does not mean that all java applications produce a .ssf file. To know the format(whatever you mean by that) of your .ssf file, you have to consult the doc of your application as it is not a java related format but some format introduced to aid the development of your UI tool
Zeeshan, it is up to you to know what kind of ssf file your application works with. Surely there must be some documentation, unless you have reverse engineered this from something you are not supposed to have and reverse engineer - is that the case?
Anyway, giving you the benefit of the doubt... As you can see, there are at least 5 known different file formats using the same extension .ssf:
[url]
http://filext.com/detaillist.php?extdetail=SSF
[/url]
And all we can see in the code is "Sedao Scene Format" and "schedule file", which doesn't point to any of those 5 as far as I can see.
So again, the only one who can provide more info is you.
I don't have any documentation regarding this application, i only have the executable files (.jar) of this application. Yes reverse engineering is the only option for me but i can't because i am not able to read the output file (.ssf) in any text editor, it just displays the symbols with litle bit text.
by reading the whole code i got that (may be i am wrong) this application is not using any rules for this formate but it just concatinate .ssf with the file name, when saving and check this extension while openning. so can you please tell me that what will be the default fomate of file generated by such java applications which draw figures (like text, line, change color etc). So that i can apply reverse engineering on it.

There is no such thing as "default format of file". An application decides exactly which bytes to put in a file, and that's what it writes.
How can you not have any documentation? Where did you get this application? And don't you think that if you need to reverse engineer something to find out its file format, maybe you're doing something illegal?
lolz
i am not doing an illegal work. i don't have anything but the jar files because this code is written by one of my seniors and this is an assignment for me to read the file through c++ and i can't able to understand this file. i can send and output file of this application. if you want to c it.

I think you need to take a step back for a moment. Go and grab a coffee and a walk around. Then come back.
You have a jar file containing an application.
From what we can see, that application opens, displays and/or generated .ssf files.
These files apparently contain graphical information of some kind.
A Java program will not generate files in a "default" format. Neither would graphical information be generated in a "default" format.
A file format is designed in much the same way as an application; you decide on the requirements and define the format to accomodate those requirements.
If this is an assignment from your "senior" you should probably go back to him/her and discuss the problem further. Make a point of telling him that you do not know how to parse the file format.
It sounds as though you have been asked to write a C++ component that is able to parse and display the result of this .ssf file. If that's the case, be prepared for some long nights...

Oh my God!! i can't compromise on my nights <SMILE>
hey you come with a good understanding of my problem but u terrified me also <smile>
as i generate a code by this jar file .... can it help u guys to solve my problem
Try a hex dump of the file and look out for random stretches of text. If you see quite a few fully qualified class names (separated by dots, some lower case names followed by a capitalised name) it's probably serialised objects.
If that's the case it's fairly insane to try and read it with C++, write a conversion program in Java. It's going to be easier to learn a small amount of Java than to convert a serialized file without it.
If it's total garbage without strings, try running it through gzip. There's a Gzip stream filter in Java so it could be, say, a serialized file which has been defalated to save space.

The bottom line is that a parser could be written that does build c++ code based on the serialized object in the ssf file. It wouldn't be easy and would probably be a candidate for "worst assignment of the year", which incidentally, is probably how long it will take...
Trust me; It's going to be easier to learn enough java to convert this file than decode it using C++.
The contents of this file are almost certainly a serialised object stream representing a network of Java objects. The good news is that if you include the jar file of the original program on your classpath you can load this network of classes with about 5 lines of java.
If you use a java IDE like Netbeans (which is a free download, by the way) it will be able to analyse the classes in the jar for you and give you names for the various methods in the classes, which will hopefully allow you to understand what data is in the objects. You can then, if necessarilly, write them out in a more C++ friendly format.
