B4J Question Error making executable updating jGoogleMaps

[jGubern]

Hi guys,

I realized a few days ago that an old project where the jGoogleMaps library participates was not working properly for me (it did not load the map).

Adapt the code according to:
https://www.b4x.com/android/forum/threads/jgooglemaps-library.56744/

And the curious thing is that in debug mode, the program works correctly,
but when I try to make the release version or the packaging that generates the exe file, the final objective is not achieved.

When I compile in release mode I get in the log:

Error: An unexpected error occurred while trying to open file C:\...\Objects\geaDesktopComplete.jar

When I'm trying to generate the .exe package

B4JPackager11 Version 1.40
Exe name: geaDesktopComplete.exe
Only Java 11, 14 and 16 are supported (Tools - Configure Paths).

any suggestions?

Thank you

Tutorial was updated and you must upgrade to open jdk 19.

jGoogleMaps library

This library is similar to B4A and B4i GoogleMaps libraries. It is based on this open source project: https://github.com/dlsc-software-consulting-gmbh/GMapsFX/ (Apache 2 license). Under the hood it uses JavaFX WebView with GoogleMaps JavaScript API V3. Using the map is quite simple. You need...

Hello jahswant,
As you can see in the previous post, I already use that version of jdk...

It’s working good here. I had this issue I think I restart b4j maybe the computer and cleaned the project!

 

[jGubern]

It's the first thing I did at the beginning but it doesn't work for me.
Thanks

Only Java 11, 14 and 16 are supported (Tools - Configure Paths).

Use java 11, 14 or 16

 

[jGubern]

Thanks @DonManfred,
but,
Am I not forced by jGoogleMaps to use OpenJDK 19.0.2?

Am I not forced by jGoogleMaps to use OpenJDK 19.0.2?

maybe. But then you need to quit using the standalone installer.

 

[jGubern]

Likewise,
it is curious that my program works perfectly in debug mode and not in release mode......

 

[Erel]

You can use the standalone packager with JDK 19 and google maps.

Are you using B4J v9.8?

 

[jGubern]

yes, @Erel

 

[Erel]

It fails to unzip the compiled jar. Does it only happen with this project? Create a new project add the library and the required #PackagerPropery statements and run it.

FWIW, I've just built a standalone package with maps and JDK 19.0.2 and it works.

 

[jGubern]

Thanks for your interest, @Erel.
It is a case that only happens in this particular project.

Fortunately, I have already found the source of the error, and it is due to a file in my project with the name:

'Sin título-1.png'

If I delete or rename it without accent, I can use release mode and use standalone packager without problems.

It seems like an issue related to character encoding.....

Thank you very much to everyone for your help !!
