Packaging the omni.ja

[RobertJ]

.
I made a tweak in the omni.ja file contents. How do I repackage it using the terminal on OSX?

Thanks

More info.

1. I removed the omni.ja file from the application
2. Unzipped it by changing "ja" to "zip" and double clicking.
3. I then rezipped the resulting omni directory without making any changes.
4. I used the terminal with the command zip -r omni.zip omni
5. Changed the resulting omni.zip to omni.ja
6. Placed the "new" omni.ja file into the application
7. Double clicked and FF crashed.
8. Placed the "original" omni.ja into the application
9. Double clicked and all was fine.

Must be something wrong with the way I'm repackaging.

Suggestions?

So this doesn't answer your question, but Don't Unpack and Repack omni.ja[r] (check the comments section).

Thanks. I would still like to know how the directory omni is packaged. Obviously it is not as simple as zipping it and renaming the suffix. I now there are other ways for certain things. This has now become one of those "puzzle" questions where you want to know simply to know.

Found this:

5. Save the file and repack omni.jar. Again, be a careful while you repack. Do not repack “omni” folder, but repack everything inside that folder. Compress it as zip, and then rename omni.zip as omni.jar

Try:
- rename omni.ja to omni.zip
- open with (in my case) WinZip, inside Application folder
- unzip files which you want to modified
- copy and overwrite modified files back to omni.zip
- rename omni.zip to omni.ja

This method works for me without crashes...

1 unzip /path/to/omni.ja -d omni
2 modified files
3 cd omni
4 zip -qr9XD omni.ja *

Back in the days of Firefox 4, I made the mistake of using compression when closing the omni.ja file after doing some mods. Firefox didn't like that.

That worked perfectly. Embarrassingly I knew that but haven't done in such a long time forgot.

Has anyone done this successfully recently? Whenever I rezip omni.ja, Firefox won't start.

Did you deoptimize the omni.ja file? And remember to purge the caches when you start up the application.

Here is an alternative to hacking the omni.ja file in some cases.

Per this MDN entry you need to use `zip -qr9XD omni.ja *`.

[therube]

(qr9XD might be the "Mozilla" way, but I wouldn't think it would matter if you simply "zip omni.ja * -r".
Hmm. And they're actually using -9, compressing, rather then -0, storing. I guess they know .)

I think you're going to have to copy/paste the link:

I successfully hacked the page title in the troubleshooting information aboutSupport.dtd file.

If I skip the deoptimize step, then the browser fails to start correctly.
