There is only jdk14.0.1

Java Platform 1.8.0 or JRE 8 is discontinued but still receive update even in my Windows 11.

The last Oracle JRE implementation, regardless of its licensing scheme, was 9.0.4.

There is no separate JRE for Java 9 and above， you can create your own Java runtime using jlink

 

[Theera]

Is there batch file(*. Bat) to create small custom jre? I'm non-expert and don't understand English well, after I have read this website.

Is the old project a B4J project?

 

[aeric]

You don't need JRE.
You can build standalone package to distribute or compile to exe using InnoSetup.

 

[aeric]

it has error.

Post the error message.

The project is not mine.I don't know its AppId. I need convert B4X Template Manager.jar to be exe file.

You need Java 1.8.x to run the jar. No need to convert to exe file.

I don't expect an upgrade from a Java 1.8 jar to be limited to a simple upgrade from Java 1.8 to Java 14. That might just be possible with a purely Java source-based jar. But a jar that is created for and uses one or more Android routines may run into new security rules and changed API calls for newer Android OS versions.
What problems do you encounter when using the original jar application?

There is the experts'examples about face dection need using java14, so I must upgrade it. After I came back to use B4X Template Manager tool to save the example, but it doesn't work again.I thinkB4XTemplateManager is useful for me as non-expert in coding.

Without some error message and example program where an error occurs, it is difficult to help you. It is also not entirely clear to me whether only the B4X Template Manager does not work or whether no programs work anymore after the update.
It is important that you have carried out the update exactly according to Erel's instructions and only use software from the indicated download links. This is because the links indicated have been specially prepared to completely install the B4X software. Do not deviate from the advice to use 7-zip, for example, and stick to the standard locations given. Then you could try a B4A program example to see if this works. If you still have problems with the B4X Template Manager, you could post the error message in this post on the forum and also provide a link to what you want to use

My problem is: there is not jre14.0.1 for running app. I can compile exe file by using theonline tool, but it can't run.

The problem is you have misunderstood.

You don't need to uninstall java 1.8!
You can still use it to open jar which is compiled with this version.

You can download java jdk 11, 14, 17, 22, etc and have multiple versions because these versions don't need to be installed. You just need to unzip them to a folder and configure the path in B4X IDE.

As I wrote before start to do exactly this instructions for B4A step by step, then you don't need JRE-14.
