B4J Question Running Jar file on Windows 7 computer

[Pelky]

I posted previously about this and have tried compiling in release which created a .jar extension app:-

C:\DevX\Legals\LegalVisits\B4J\Objects\LegalVisits.jar

As I understand it this will only run on windows 7 and I cannot test it on a windows 11 computer

I used Java 8 when compiling.

I want to be able to install the app on a network shared drive which is all windows 7

Is there anything else I need when distributing it - Folders etc. or just put the .jar on the shared drive and create a link on the desktop?

I thank you all for your assistance.

Better to start with the integrated packager: https://www.b4x.com/android/forum/threads/integrated-b4jpackager11-the-simple-way-to-distribute-standalone-ui-apps.117880/ B4JPackager11 is a B4J non-ui program that builds a package with your app jar and an embedded modularized Java runtime. It...

that posting is somewhat meaningless... it states 2 ways to run it but only shows one... states create a json file = is that a text file with an extention or not?

I was told I had to go with java 8 as that is what is required for windows 7 but the posting b4jpackager11 does not say anything about java 8

will that packager do a java 8 version?

states create a json file

If you don’t understand or clear about the json file, you are welcome to ask. It is just a config file. Please try to understand first before drawing any conclusion.

I was told I had to go with java 8

Not sure how you were told. You are not forced to use Java 8. Java 11 can work in Windows 7 too.

I used Java 8 when compiling

What’s the reason to use Java 8? You want it to create an executable Jar file? If you create a package using B4JPackager11, you can create an installation exe (with Innosetup) and distribute your app. After installed, user can run the app using an exe executable.

Great and accurate answers @aeric. Thank you.

Sorry, my mistake, I always take the older post. It has a link to the newer tutorial. I will take note in the future.

thank you for your response. If I caused some offence with my previous response I apologise as that was not my intension - perhaps just letting the frustration get to me.

Having to use java 8 was a response that I got from a previous request for the same information. Maybe I read it wrong

Thank you for your response - If I caused some offence please accept my apologies, that was not my intension. Perhaps my frustrations coming out.

I received a response in a previous posting -
"No. Run the app in Release mode and it will create a jar file that you can distribute with two important nuances:-"

1. You need to compile with Java 8 (11+ will not work).
2. Java 8 needs to be installed on the user computer.

Perhaps I was just confused and took this response as the final say..... Once again my apologies

The installation is for a windows 7 computer on a shared drive using windows 7. I would like the best and simplest way to load this application allowing multiple users on the network to access and run it. I thought a standalone exe with associated folders was the easiest way.

so if I create an installation exe (with Innosetup) this will create an area/folder with everything I need to distribute this application? Also I can continue developing with java 11?
So just to get it right - I run b4jpackager11 and then Innosetup (found on the forum?)

I am sorry but I am just this side of 70 and all these new ways and naming conventions confuses me. I come from an historic mainframe environment where you just compiled the code (cobol) and copied the cob into where you want and you were off and running. I am a bit of a dinosaur.

Once again thank you for your assistance.


just out of interest - 'It is just a config file' - does that file have an extension or just a plain xxx.txt?

I would like to let you know that I found out what the b4jpackager11 was and then found the Innosetup application on the internet
and ran it ..... it looks good and is running..
I havent tried it on the windows 7 computer yet but just wanted to let you know that the setup and installation was just
what I was looking for and it all just seems so much more simple .....

Thank you so much for your assistance it is much appreciated

You have to reopen the Thread first ;-)

I wasn't clear. I meant that it is better to post the link to the built-in packager tutorial.
