B4J Question Standalone App Not Sending Email (Sending from IDE Works)

[B4XDev]

I have an app that allows me to send email. When I run the app via the IDE and try to send the email, it sends successfully.

When I try to send it from the Standalone version, it does not work. I get this error message:

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

I'm not using obfuscation.

Anybody know what might be happening here and how to fix it?

Thank you!

[SOLVED] B4JPackager11 error javax.net.ssl.SSLHandshakeException

Hi, I build myapplication using java11 (downloaded from this site) and it run well when using java. When i package myapplication using B4JPackager11, it show error: D:\B4JPackager11\Objects\temp\build\bin>java.exe @release_java_modules.txt -m b4j/b4j.webapps.main...

Whenever the standalone packaged version of an app I create doesn't run, but it does in the IDE, I always refer to the tips in Integrated B4JPackager11 - The simple way to distribute standalone UI apps and in this case Tip 7 applies as @Mariano Ismael Castro has implied:

7. If you get an error that looks like: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure, add:

#PackagerProperty: IncludedModules = jdk.crypto.ec

Yes, that fixes my issue!

I should have known to search for that error message specifically instead of a general description of the problem. :-/

Thank you!
