B4J Question B4J V. 9.30

[Dey]

Hello everybody,

where can I download version B4J 9.30?
i tried the new version 9.80 but i have problems with my app.
I have to find the time to convert it to the new version.
Thank you

The new version is 100% backward compatible. Which error have you encountered?

public static anywheresoftware.b4j.object.ServerWrapper _srvr = null;

bad class file: C:\Program Files\Anywhere Software\B4J\libraries\jserver.jar(anywheresoftware/b4j/object/ServerWrapper.class)

Please remove or make sure it appears in the correct subdirectory of the classpath.

thanks for your great help

Download jServer3 and use it instead of jServer.

jServer3 / jServer 4 - previous versions of jServer

jServer 5, based on Jetty 12.1.10, is included with B4J v10.7+. It requires Java 17+. Instructions: https://www.b4x.com/android/forum/threads/jserver-5-based-on-jetty-12-1.171536/ Previous versions of jServer: jServer4.1, based on Jetty 11.0.26: https://www.b4x.com/b4j/files/jServer4.zip...

When you are ready to switch to Java 11 (which is usually trivial to do), switch back to jServer.
