B4J Question Wasn't there a handy way to set the java compiler?

[sorex]

Hello,

Wasn't there a way to set the compiler to use inside a project?

I'm asking because I have some misery to get an ssd1306 oled display working that's included on a raspberry pi poe hat.

The culprit seems to be the removal of a shared secrets lib ( Caused by: java.lang.ClassNotFoundException: sun.misc.SharedSecrets ).

So I would like to try to compile this to open or oracle jdk 8.x without messing up other things.

Running it via jre8 on the pi doesn't work as it detects that it was compiled with a newer version.

Forum search for "java compiler" works

B4J v8.80 has been released 🍾

Download link: https://www.b4x.com/b4j.html Libraries tab improvements. Indicators to help understand the code flow with resumable subs. IDE performance improvements related to handling of b4xlibs. The deprecated jHttp and jHttpUtils2 libraries were removed. OkHttp updated. #JavaCompilerPath...

Look for

#JavaCompilerPath attribute. Allows setting a JDK other than the one set in the global settings. Syntax: <java version>, <path to javac.exe>. The exact version isn't important

indeed, this works

#JavaCompilerPath: 8, C:\Program Files\Java\jdk1.8.0_144\bin\javac.exe

can this be done for the execution through the bridge aswell?

now it compiles, runs, quits from the error.

then I have to see what number that AsyncInput file has and then use java -jar AsyncInput<number>

which mean constantly switching between windows, pi os at each compile.

Sorry, but the post above means nothing to me

B4J-Bridge uses the Java version that it was started with. It cannot be changed without restarting B4J-Bridge.
