Hi everyone,
I have been thinking about creating a simple utility that can crack the existing bar file open and build the mqsicreatebar script based on the given BAR contents.
So finally found some time to do that and would like to share it in this community.
I think it may be very useful in some situations as it uses only generic Java apis from the JVMs and runs independently from the broker, toolkit and eclipse.
The way it works is in cmd console you launch the JAR file attached:
java -jar <Path>\BARCracker.jar
This brings up a dialog where user needs to specify a BAR file, workspace where the projects are(to be used in -data) and also can set some common flags (the flags may work or not work depending on the toolkit version you have).
When the "Generate" button is clicked the tool will create a mqsicreatebar script based on the BAR file data.
Then if run on Windows the script automatically can be opened in notepad. The script is saved to the same directory where the specified bar is.
If you want to try this utility please reply to this note and let me know the address where to send the jar file to.
My email is: kharlamov.eugene@gmail.com.
Thanks. |

Eugene,
Your proposal is technically infeasible. You do not have the generalized workspace name or the source available. Therefore, your attempt to build an mqsicreatebar command line would be inadequate.
There is no replacement for version control. Write source code, then save the source code to a version control system.
This post seems like spam to me, and wonder what actually the Jar does, since it cannot do what you purport it to do. You may be able to derive a command line out of the forensics, but you would not be able to recreate the source code files. What good would a command line do without source code ?
Lance

while you can make some reasonable guesses as to source names based on things like cmf file names and some of the path info, in the general case I agree that you can't make a firm link between the contents of a random bar file and the workspace resources that produced it.
In particular, it's going to be ... complicated at best to guess whether the contents of a JAR file represent workspace source files or project includes or etc. etc. etc.
Now, if the prerequesite is that you provide both the bar file in question AND the workspace that built it - which it seems slightly possible is what is described here, then it's an easier problem.
But then it doesn't seem a terribly useful tool for most purposes. |

Lancelotlinc,
From his description, you are supplying the location of the workspace where the .bar file was originally built. This possibly would allow the generation of a script as decribed.
Why don't you try it out in a VM and report back? I'm sure we'd all value your feedback...

I value my bank account and tax return info far more than BarCracker utility. ^^ This smells to me like a Trojan horse.

It's interesting how much you can deduce by just looking at the original post info:
"- It's useless;
- It's a Trojan;
- It would not work.
I applaude your deep insight 
Now in response to the quesions.
A. It does not care about the workspace. It needs the wokspace parameter just build the script (-data) ( I assume peple can just update th generated script manuallly if the workspace changes);
B. If you don't have anything there of course the script won't work when you try to execute it. But in order to create the script you actually don't need the projects or artefacts on the workspace.
C. It's not intended to replace any source control system.
D. I find it useful in the cases when my mqsicratebar script from the source control sytem does not work for some reason.
Often I saw it does not work because the script may be outdated compared to th source on the workspace.
And in these cases I use this utility to get me the script based on the exisig BAR and it will tell me what projects and artifats are expcted to be on the workspace.
And finally:
If you want to try you can send an e-mail to me. If you don't need it feel free to ignore me  |

It's possible I've considered the problem before.

Eugene, you have not provided enough detail to make even the smallest business case to consider your utility.
People who are smart enough to use Message Broker don't need a GUI tool to create a command line for them.
They should be smart enough to write their own command line and if not, find a new line of work.

Well, anyway this thing works for me. |

What would really be slick is a Ant generator utility run from Eclipse to create Ant scripts that build bar files.
Maybe what you have is the start of something more towards that end?
What would it take to integrate your utility to Eclipse and rather than create a command line, create an Ant file?

Dear Sir Lancelot,
Your point is taken. 
Please feel free to read anything else that fits your intelligence level. |
