[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)
class file has wrong version 55.0, should be 52.0
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

jServer3 library is the previous version of jServer library. It is the library that was included with B4J up until B4J v9.80. Starting from B4J v9.80, the included jServer library is jServer 4: https://www.b4x.com/android/forum/threads/jserver-v4-0-based-on-jetty-11.140437/#content. Main...

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