不能使用从代号一创建 CEF 浏览器

Question

My app is failing to run the BrowserComponent everytime I try to call it inside codename one. It gives me an error of failure to create CEF browser. Everything beside that is running just fine. I uninstalled and installed CEF as instructed in this link Codename One CEF Support I tried to fix my problem as I found it inside Known Issues from the previous link

I did as instructed and tried to fix the LD_LIBRARY_PATH

here is the output of my terminal after I did so:

[kagha@archbios ~]$ whereis java
java: /usr/bin/java /usr/share/java /usr/lib/jvm/java-8-jdk/bin/java
[kagha@archbios ~]$ echo $JAVA_HOME
/usr/lib/jvm/java-8-jdk
[kagha@archbios ~]$ echo  $LD_LIBRARY_PATH
/usr/lib/jvm/java-8-jdk/lib/amd64
[kagha@archbios ~]$ find /usr/lib/jvm/java-8-jdk/ | grep "libawt.so"
/usr/lib/jvm/java-8-jdk/jre/lib/amd64/libawt.so

but the problem is still there I am using the OS Arch Linux with Kernel version 5.10.32-1-lts and Apache netbeans 12.1 as an IDE

The code I am trying to run

Form hi = new Form("Browser", new BorderLayout());
BrowserComponent browser = new BrowserComponent();
browser.setURL("https://www.codenameone.com/");
hi.add(BorderLayout.CENTER, browser);*/

Here is the full error in the console:

I will appreciate any help and provide more information if needed, thanks in advance

Answer 1

You should use the new Maven support . This should fix issue as the Maven plugin will automatically add the needed entries to the LD_LIBRARY_PATH .

You can download a base template from https://start.codenameone.com and just paste your code there.
