B4J Question jServer-11.0.20 & jServer-11.0.21 packaging error

Chris2 · Jul 15, 2024

I've been trying out the updated versions of jServer posted by @tchart here (thanks for posting these @tchart!)
I've had no problems running my jRDC2 based app in debug & release mode but get the following errors when trying to build a standalone package:

Packaging error 1 with jserver-11.0.21:

The app still packages correctly with the original jServer v4.0 version supplied internally within the latest B4J.

Can anyone tell me what's causing these packaging errors and how I can fix them?
Do I need to add an extra #PackagerProperty?

I already have all the #PackagerProperty settings from the jServer v4.0 thread:

B4X:

    #PackagerProperty: AdditionalModuleInfoString = provides org.slf4j.spi.SLF4JServiceProvider with org.eclipse.jetty.logging.JettyLoggingServiceProvider;
    #PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.io.ssl.ALPNProcessor.Server with org.eclipse.jetty.alpn.java.server.JDK9ServerALPNProcessor;
    #PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.http.HttpFieldPreEncoder with org.eclipse.jetty.http2.hpack.HpackFieldPreEncoder, org.eclipse.jetty.http.Http1FieldPreEncoder;
    #PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.util.security.CredentialProvider;
    #PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.io.ssl.ALPNProcessor.Server;
    #PackagerProperty: IncludedModules = jdk.charsets, jdk.crypto.ec

Many thanks.

Solution Update: As well as the post marked as the solution, see also post #8 for an explanation of how the errors above were solved by @teddybear .
Update 2: As well as those listed in @teddybear's solution, I had to add java.desktop to the list of includedModules (#PackagerProperty: IncludedModules =...) to prevent an error (java.lang.NoClassDefFoundError: java/beans/PropertyChangeListener) when running the app from the package.
(possibly needed only with an MS SQL Server database in use)

To build a standalone package using jserver-11.0.21, you need to adapt some packages of the library for that.
1. A modified jserver-11.0.21 is attached
2.Add some modules to PackagerProperty if they are necessary

B4X:

#PackagerProperty: IncludedModules = jdk.charsets, jdk.crypto.ec,java.sql,java.instrument,java.xml,java.security.jgss,java.rmi,java.naming,java.management

Hi @Chris2 I dont use B4JPackager11 so Im only assuming here. Did you download the version I posted or did you configure it yourself?

Can you confirm youve got the jar files for http2?

And that its shown in the XML?

Chris2 · Jul 16, 2024

Thanks for your help @tchart.
I downloaded directly from your post, and all looks OK with the jar files & in the XML:

Update: Just to be clear, at this point I am still getting the same errors mentioned in my first post.

That seems to have sorted the problem for me, thanks @teddybear! With your jServer-11.0.21 version I can now package jRDC2.

For everyone's information can you say please what you changed within the jServer-11.0.21 files?
Based on the file modified dates, it looks to me like you've altered something in jetty-io-11.0.21.jar, jetty-alpn-java-server-11.0.21.jar, http2-server-11.0.21.jar, http2-hpack-11.0.21.jar, http2-common-11.0.21.jar, & jetty-alpn-server-11.0.21.jar?

tchart · Jul 17, 2024

@teddybear i’m also interested to know what you changed

aeric · Jul 17, 2024

Is it because of timezone difference so the file date is different?

teddybear · Jul 17, 2024

What I did was remove

What I did was remove the module info from these jars. and you can also do that for jserver-11.0.20.

tchart · Jul 17, 2024

Thanks @teddybear, so you just removed module-info.class from the jars? I'll make sure to do that next time I upload a new version.

tchart · Jul 17, 2024

In case you want to do this yourself, heres a batch file that will remove the file from all jar files in a directory using 7za.

INI:

@echo off

SET ZA=C:\Apps\7za\7za.exe

FOR /F "tokens=*" %%G IN ('dir /b *.jar') DO %ZA% d %%G module-info.class

pause
