Well, you can do it, but update4j uses a separate thread by design. If you copy the launch code and remove the thread spawning you might get it to work on your own.
This line spawns the thread. The actual launch can skip this step, it's just here to give the business application a separate context.

Thanks, I'll give this a shot.

@metzlerd_gitlab
@mordechaim I tried this but ran into troubles as the constructor for LaunchContext is not public, so I couldn't new up a LaunchContext outside of the package. Is that something you would be willing to change?
Mordechai Meisels
@mordechaim
I don't think I'm going to change this. You could sort-of reimplement the whole launch process with your own logic using my code as helpful pointers. Or you can fork the project.

Hello all i need help in how to use update4j in ant project
David Metzler
@metzlerd_gitlab
@mordechaim Thank you for considering. I have worked around this problem by using a two executable strategy that you documented in the Wiki and just using update4j for managing the upgrade process and not for launching. Wanted you to know that I still appreciated the work.
@foula_ly_twitter - could you be more specific? You could simply download the jar and include it as a dependancy. Not sure what is difficult about using upate4j in ant?

Hi, i have a modular application with openjdk 11 and i'm newby in the java world. Is it possible to update modular applications with update4j? I read link https://github.com/update4j/update4j/wiki/Documentation#integration-with-jlink but, i dont understand this. Do i have to replace bat/sh file generate jlink for the example in documentation?
thanks!
Mordechai Meisels
@mordechaim
@fkmurphy yes it is possible, but not when its part of the jlink image.
Julián Murphy
@fkmurphy
my application runs from the jlink generated script, therefore it is not possible. Alternatives?

Hi, my application ist a runnable jar built with jdk 1.8. Is it possible to use update4j for this? Is there a tutorial which shows the steps from a runnable jar to the auto-updating application?
Mordechai Meisels
@mordechaim
While update4j wasnt designed for jdk8 there are a few forks that packported the project. Check out here.
There aren't any special rules regarding runnable jar files, but update4j will not handle it as runnable. Namely, you'll need to supply the main class the update4j (if you use the default bootstrap setup).
Start update4j as a runnable jar to see a quick reference guide

Hi, I started to use update4j for update my application. I get the exemple bootstrap. I created my config.xml and make download functional. But I have a problem with the launch part
I want to start my application inside the current jvm (from bootstrap)
Currently I can start my business app with"java -classpath 'exemple.jar; exemple2.jar ..." com.me.MainClass
But with the bootstrap I don't succeed in launch it
I add classpath="true" in all jar inside config.xml but I have an error when I launch my businness app :
Caused by: java.lang.IllegalAccessError: class com.eukles.resoposte.AgentResoposteV2 (in unnamed module @0x6dc7625e) cannot access class com.sun.javafx.application.LauncherImpl (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.application to unnamed module @0x6dc7625e
Have you an idea to solve my problem please ?
Mordechai Meisels
@mordechaim
Are your example.jar files also liated in the config?
Do you use the default bootstrap or your own?
Mordechai Meisels
@mordechaim
*listed in the config
Sébastien Gonzalez
@SebGonzalez
Yes I have all my jar in the "<files>"
<files>
<file path="antlr-2.7.7.jar" size="445288" checksum="d0d1c0e2" classpath="true"/>
<file path="aspectjweaver-1.9.6.jar" size="2051606" checksum="b7eba520" classpath="true"/>
<file path="byte-buddy-1.10.19.jar" size="3497763" checksum="2de28ed8" classpath="true"/>
......
</files>
I take the demo-boostrap from here : https://github.com/update4j/demo-bootstrap

@SebGonzalez maybe this will help: https://stackoverflow.com/questions/59625091/javafx-module-does-not-export-to-unnamed-module
I do not know how to achieve this in update4j.
Sébastien Gonzalez
@SebGonzalez
I tried to add export on the file "javafx-graphics-16.jar" in the config but I have the same error
<file path="javafx-graphics-16.jar" size="306" checksum="3d6046ce" classpath="true">
<addExports>
<exports package="javafx.graphics/com.sun.javafx.application" target="ALL-UNNAMED"/>
</addExports>
</file>
Mordechai Meisels
@mordechaim
With not enough context information, can you try to not include your jars in the classpath from the start command? Just include update4j alone and let the launcher do the rest.
Sébastien Gonzalez
@SebGonzalez
If i don't include jars in the classpath when I try to launch with the "config.launch(this);" command i have the next result ;
Caused by: java.lang.ClassNotFoundException: com.eukles.resoposte.AgentResoposteV2
My main jar is not include so he dosn't know the main class
Mordechai Meisels
@mordechaim
As I said I'm missing a lot of context, but my best guess is to try using the DynamicClassLoader as explained here.
Sébastien Gonzalez
@SebGonzalez
I didn't understand how to use it
DynamicClassLoader dynamicClassLoader = new DynamicClassLoader(); ?
Mordechai Meisels
@mordechaim
$ java -Djava.system.class.loader=org.update4j.DynamicClassLoader <your commands here>
Sébastien Gonzalez
@SebGonzalez
I need to launch my bootstrap with this arg ? "-Djava.system.class.loader=org.update4j.DynamicClassLoader"
Sébastien Gonzalez
@SebGonzalez
When I try with this arg and remove all ".classPath()" method in the config.xml I get this error :

Astrid Sawatzky
@astridsawatzky_gitlab
can you add the export declaration from above to the call on commandline ?
Sébastien Gonzalez
@SebGonzalez
Yes it works thanks you @astridsawatzky_gitlab and @mordechaim !
Just a question if I want to inject the stage with @InjectSource I need that my main app implements Launcher ?
Mordechai Meisels
@mordechaim
Yes
